and classes for make ESLint custom rules. - -For examples: - -- [`getStaticValue`](https://eslint-community.github.io/eslint-utils/api/ast-utils.html#getstaticvalue) evaluates static value on AST. -- [`ReferenceTracker`](https://eslint-community.github.io/eslint-utils/api/scope-utils.html#referencetracker-class) checks the members of modules/globals as handling assignments and destructuring. - -## 📖 Usage - -See [documentation](https://eslint-community.github.io/eslint-utils). - -## 📰 Changelog - -See [releases](https://github.com/eslint-community/eslint-utils/releases). - -## ❤️ Contributing - -Welcome contributing! - -Please use GitHub's Issues/PRs. - -### Development Tools - -- `npm run test-coverage` runs tests and measures coverage. -- `npm run clean` removes the coverage result of `npm run test-coverage` command. -- `npm run coverage` shows the coverage result of the last `npm run test-coverage` command. -- `npm run lint` runs ESLint. -- `npm run watch` runs tests on each file

Each config array contains the information needed to determine the correct configuration for any file based on the filename. - -**Note:** This is a generic package that can be used outside of ESLint. It contains no ESLint-specific functionality. - -## Installation - -For Node.js and compatible runtimes: - -```shell -npm install @eslint/config-array -# or -yarn add @eslint/config-array -# or -pnpm install @eslint/config-array -# or -bun add @eslint/config-array -``` - -For Deno: - -```shell -deno add @eslint/config-array -``` - -## Background - -The basic idea is that all configuration, including overrides, can be represented by a single array where each item in the array is a config object. Config objects appearing later in the array override config objects appearing earlier in the array. You can calculate a config for a given file by traversing all config objects in the array to find the ones that match the filename. Matching is done by specifying glob patterns in `files` and `ignores` properties on each config object. Here's an example: - -```js -export default [ - // match all JSON files - { - name: "JSON Handler", - files: ["**/*.json"], - handler: jsonHandler, - }, - - // match only package.json - { - name: "package.json Handler", - files: ["package.json"], - handler: packageJsonHandler, - }, -]; -``` - -In this example, there are two config objects: the first matches all JSON files in all directories and the second matches just `package.json` in the base path directory (all the globs are evaluated as relative to a base path that can be specified). When you retrieve a configuration for `foo.json`, only the first config object matches so `handler` is equal to `jsonHandler`; when you retrieve a configuration for `package.json`, `handler` is equal to `packageJsonHandler` (because both config objects match, the second one wins). - -## Usage - -First, import the `ConfigArray` constructor: - -```js -import { ConfigArray } from "@eslint/config-array"; - -// or using CommonJS - -const { ConfigArray } = require("@eslint/config-array"); -``` - -When you create a new instance of `ConfigArray`, you must pass in two arguments: an array of configs and an options object. The array of configs is most likely read in from a configuration file, so here's a typical example: - -```js -const configFilename = path.resolve(process.cwd(), "my.config.js"); -const { default: rawConfigs } = await import(configFilename); -const configs = new ConfigArray(rawConfigs, { - // the path to match filenames from - basePath: process.cwd(), - - // additional items in each config - schema: mySchema, -}); -``` - -This example reads in an object or array from `my.config.js` and passes it into the `ConfigArray` constructor as the first argument. The second argument is an object specifying the `basePath` (the directory in which `my.config.js` is found) and a `schema` to define the additional properties of a config object beyond `files`, `ignores`, `basePath`, and `name`. - -### Specifying a Schema - -The `schema` option is required for you to use additional properties in config objects. The schema is an object that follows the format of an [`ObjectSchema`](https://npmjs.com/package/@eslint/object-schema). The schema specifies both validation and merge rules that the `ConfigArray` instance needs to combine configs when there are multiple matches. Here's an example: - -```js -const configFilename = path.resolve(process.cwd(), "my.config.js"); -const { default: rawConfigs } = await import(configFilename); - -const mySchema = { - - // define the handler key in configs - handler: { - required: true, - merge(a, b) { - if (!b) return a; - if (!a) return b; - }, - validate(value) { - if (typeof value !== "function") { - throw new TypeError("Function expected."); - } - } - } -}; - -const configs = new ConfigArray(rawConfigs, { - - // the path to match filenames from - basePath: process.cwd(), - - // additional item schemas in each config - schema: mySchema, - - // additional config types supported (default: []) - extraConfigTypes: ["array", "function"]; -}); -``` - -### Config Arrays - -Config arrays can be multidimensional, so it's possible for a config array to contain another config array when `extraConfigTypes` contains `"array"`, such as: - -```js -export default [ - // JS config - { - files: ["**/*.js"], - handler: jsHandler, - }, - - // JSON configs - [ - // match all JSON files - { - name: "JSON Handler", - files: ["**/*.json"], - handler: jsonHandler, - }, - - // match only package.json - { - name: "package.json Handler", - files: ["package.json"], - handler: packageJsonHandler, - }, - ], - - // filename must match function - { - files: [filePath => filePath.endsWith(".md")], - handler: markdownHandler, - }, - - // filename must match all patterns in subarray - { - files: [["*.test.*", "*.js"]], - handler: jsTestHandler, - }, - - // filename must not match patterns beginning with ! - { - name: "Non-JS files", - files: ["!*.js"], - settings: { - js: false, - }, - }, - - // specific settings for files inside `src` directory - { - name: "Source files", - basePath: "src", - files: ["**/*"], - settings: { - source: true, - }, - }, -]; -``` - -In this example, the array contains both config objects and a config array. When a config array is normalized (see details below), it is flattened so only config objects remain. However, the order of evaluation remains the same. - -If the `files` array contains a function, then that function is called with the path of the file as it was passed in. The function is expected to return `true` if there is a match and `false` if not. (The `ignores` array can also contain functions.) - -If the `files` array contains an item that is an array of strings and functions, then all patterns must match in order for the config to match. In the preceding examples, both `*.test.*` and `*.js` must match in order for the config object to be used. - -If a pattern in the files array begins with `!` then it excludes that pattern. In the preceding example, any filename that doesn't end with `.js` will automatically get a `settings.js` property set to `false`. - -You can also specify an `ignores` key that will force files matching those patterns to not be included. If the `ignores` key is in a config object without any other keys, then those ignores will always be applied; otherwise those ignores act as exclusions. Here's an example: - -```js -export default [ - - // Always ignored - { - ignores: ["**/.git/**", "**/node_modules/**"] - }, - - // .eslintrc.js file is ignored only when .js file matches - { - files: ["**/*.js"], - ignores: [".eslintrc.js"] - handler: jsHandler - } -]; -``` - -You can use negated patterns in `ignores` to exclude a file that was already ignored, such as: - -```js -export default [ - // Ignore all JSON files except tsconfig.json - { - files: ["**/*"], - ignores: ["**/*.json", "!tsconfig.json"], - }, -]; -``` - -### Config Functions - -Config arrays can also include config functions when `extraConfigTypes` contains `"function"`. A config function accepts a single parameter, `context` (defined by you), and must return either a config object or a config array (it cannot return another function). Config functions allow end users to execute code in the creation of appropriate config objects. Here's an example: - -```js -export default [ - // JS config - { - files: ["**/*.js"], - handler: jsHandler, - }, - - // JSON configs - function (context) { - return [ - // match all JSON files - { - name: context.name + " JSON Handler", - files: ["**/*.json"], - handler: jsonHandler, - }, - - // match only package.json - { - name: context.name + " package.json Handler", - files: ["package.json"], - handler: packageJsonHandler, - }, - ]; - }, -]; -``` - -When a config array is normalized, each function is executed and replaced in the config array with the return value. - -**Note:** Config functions can also be async. - -### Normalizing Config Arrays - -Once a config array has been created and loaded with all of the raw config data, it must be normalized before it can be used. The normalization process goes through and flattens the config array as well as executing all config functions to get their final values. - -To normalize a config array, call the `normalize()` method and pass in a context object: - -```js -await configs.normalize({ - name: "MyApp", -}); -``` - -The `normalize()` method returns a promise, so be sure to use the `await` operator. The config array instance is normalized in-place, so you don't need to create a new variable. - -If you want to disallow async config functions, you can call `normalizeSync()` instead. This method is completely synchronous and does not require using the `await` operator as it does not return a promise: - -```js -await configs.normalizeSync({ - name: "MyApp", -}); -``` - -**Important:** Once a `ConfigArray` is normalized, it cannot be changed further. You can, however, create a new `ConfigArray` and pass in the normalized instance to create an unnormalized copy. - -### Getting Config for a File - -To get the config for a file, use the `getConfig()` method on a normalized config array and pass in the filename to get a config for: - -```js -// pass in filename -const fileConfig = configs.getConfig( - path.resolve(process.cwd(), "package.json"), -); -``` - -The config array always returns an object, even if there are no configs matching the given filename. You can then inspect the returned config object to determine how to proceed. - -A few things to keep in mind: - -- If a filename is not an absolute path, it will be resolved relative to the base path directory. -- The returned config object never has `files`, `ignores`, `basePath`, or `name` properties; the only properties on the object will be the other configuration options specified. -- The config array caches configs, so subsequent calls to `getConfig()` with the same filename will return in a fast lookup rather than another calculation. -- A config will only be generated if the filename matches an entry in a `files` key. A config will not be generated without matching a `files` key (configs without a `files` key are only applied when another config with a `files` key is applied; configs without `files` are never applied on their own). Any config with a `files` key entry that is `*` or ends with `/**` or `/*` will only be applied if another entry in the same `files` key matches or another config matches. - -## Determining Ignored Paths - -You can determine if a file is ignored by using the `isFileIgnored()` method and passing in the path of any file, as in this example: - -```js -const ignored = configs.isFileIgnored("/foo/bar/baz.txt"); -``` - -A file is considered ignored if any of the following is true: - -- **It's parent directory is ignored.** For example, if `foo` is in `ignores`, then `foo/a.js` is considered ignored. -- **It has an ancestor directory that is ignored.** For example, if `foo` is in `ignores`, then `foo/baz/a.js` is considered ignored. -- **It matches an ignored file pattern.** For example, if `**/a.js` is in `ignores`, then `foo/a.js` and `foo/baz/a.js` are considered ignored. -- **If it matches an entry in `files` and also in `ignores`.** For example, if `**/*.js` is in `files` and `**/a.js` is in `ignores`, then `foo/a.js` and `foo/baz/a.js` are considered ignored. -- **The file is outside the `basePath`.** If the `basePath` is `/usr/me`, then `/foo/a.js` is considered ignored. - -For directories, use the `isDirectoryIgnored()` method and pass in the path of any directory, as in this example: - -```js -const ignored = configs.isDirectoryIgnored("/foo/bar/"); -``` - -A directory is considered ignored if any of the following is true: - -- **It's parent directory is ignored.** For example, if `foo` is in `ignores`, then `foo/baz` is considered ignored. -- **It has an ancestor directory that is ignored.** For example, if `foo` is in `ignores`, then `foo/bar/baz/a.js` is considered ignored. -- **It matches and ignored file pattern.** For example, if `**/a.js` is in `ignores`, then `foo/a.js` and `foo/baz/a.js` are considered ignored. -- **If it matches an entry in `files` and also in `ignores`.** For example, if `**/*.js` is in `files` and `**/a.js` is in `ignores`, then `foo/a.js` and `foo/baz/a.js` are considered ignored. -- **The file is outside the `basePath`.** If the `basePath` is `/usr/me`, then `/foo/a.js` is considered ignored. - -**Important:** A pattern such as `foo/**` means that `foo` and `foo/` are _not_ ignored whereas `foo/bar` is ignored. If you want to ignore `foo` and all of its subdirectories, use the pattern `foo` or `foo/` in `ignores`. - -## Caching Mechanisms - -Each `ConfigArray` aggressively caches configuration objects to avoid unnecessary work. This caching occurs in two ways: - -1. **File-based Caching.** For each filename that is passed into a method, the resulting config is cached against that filename so you're always guaranteed to get the same object returned from `getConfig()` whenever you pass the same filename in. -2. **Index-based Caching.** Whenever a config is calculated, the config elements that were used to create the config are also cached. So if a given filename matches elements 1, 5, and 7, the resulting config is cached with a key of `1,5,7`. That way, if another file is passed that matches the same config elements, the result is already known and doesn't have to be recalculated. That means two files that match all the same elements will return the same config from `getConfig()`. - -## Acknowledgements - -The design of this project was influenced by feedback on the ESLint RFC, and incorporates ideas from: - -- Teddy Katz (@not-an-aardvark) -- Toru Nagashima (@mysticatea) -- Kai Cataldo (@kaicataldo) - -## License - -Apache 2.0 - - - - -## Sponsors - -The following companies, organizations, and individuals support ESLint's ongoing maintenance and development.

They behave the same. - * - `*(foo|bar)` - Matches _n_ instances of `{foo,bar}`. - * - `+(foo|bar)` - Matches _n > 0_ instances of `{foo,bar}`. - * - `!(foo|bar)` - Matches anything other than `{foo,bar}`. - * - See https://www.linuxjournal.com/content/bash-extended-globbing. - * - * Globstar syntax: - * - Requires `{ globstar: true }`. - * - `**` - Matches any number of any path segments. - * - Must comprise its entire path segment in the provided glob. - * - See https://www.linuxjournal.com/content/globstar-new-bash-globbing-option. - * - * Note the following properties: - * - The generated `RegExp` is anchored at both start and end. - * - Repeating and trailing separators are tolerated. Trailing separators in the - * provided glob have no meaning and are discarded. - * - Absolute globs will only match absolute paths, etc. - * - Empty globs will match nothing. - * - Any special glob syntax must be contained to one path segment. For example, - * `?(foo|bar/baz)` is invalid. The separator will take precedence and the - * first segment ends with an unclosed group. - * - If a path segment ends with unclosed groups or a dangling escape prefix, a - * parse error has occurred. Every character for that segment is taken - * literally in this event. - * - * Limitations: - * - A negative group like `!(foo|bar)` will wrongly be converted to a negative - * look-ahead followed by a wildcard. This means that `!(foo).js` will wrongly - * fail to match `foobar.js`, even though `foobar` is not `foo`. Effectively, - * `!(foo|bar)` is treated like `!(@(foo|bar)*)`.

Here's an example: - -```js -// eslint.config.js -import { defineConfig, globalIgnores } from "@eslint/config-helpers"; - -export default defineConfig([ - { - files: ["src/**/*.js"], - rules: { - semi: "error", - "prefer-const": "error", - }, - }, - globalIgnores(["node_modules/", "dist/", "coverage/"]), -]); -``` - -## License - -Apache 2.0 - - - - -## Sponsors - -The following companies, organizations, and individuals support ESLint's ongoing maintenance and development.

Instead of defining `merge()` and `validate()`, assign a `schema` key that contains a schema definition, like this: - -```js -const schema = new ObjectSchema({ - name: { - schema: { - first: { - merge: "replace", - validate: "string", - }, - last: { - merge: "replace", - validate: "string", - }, - }, - }, -}); - -schema.validate({ - name: { - first: "n", - last: "z", - }, -}); -``` - -### Remove Keys During Merge - -If the merge strategy for a key returns `undefined`, then the key will not appear in the final object. For example: - -```js -const schema = new ObjectSchema({ - date: { - merge() { - return undefined; - }, - validate(value) { - Date.parse(value); // throws an error when invalid - }, - }, -}); - -const object1 = { date: "5/5/2005" }; -const object2 = { date: "6/6/2006" }; - -const result = schema.merge(object1, object2); - -console.log("date" in result); // false -``` - -### Requiring Another Key Be Present - -If you'd like the presence of one key to require the presence of another key, you can use the `requires` property to specify an array of other properties that any key requires. For example: - -```js -const schema = new ObjectSchema(); - -const schema = new ObjectSchema({ - date: { - merge() { - return undefined; - }, - validate(value) { - Date.parse(value); // throws an error when invalid - }, - }, - time: { - requires: ["date"], - merge(first, second) { - return second; - }, - validate(value) { - // ... - }, - }, -}); - -// throws error: Key "time" requires keys "date" -schema.validate({ - time: "13:45", -}); -``` - -In this example, even though `date` is an optional key, it is required to be present whenever `time` is present. - -## License - -Apache 2.0 - - - - -## Sponsors - -The following companies, organizations, and individuals support ESLint's ongoing maintenance and development.

They implement the correct interfaces to return from the `SourceCode#traverse()` method. - -The `VisitNodeStep` class is the more common of the two, where you are describing a visit to a particular node during the traversal. The constructor accepts three arguments: - -- `target` - the node being visited. This is used to determine the method to call inside of a rule. For instance, if the node's type is `Literal` then ESLint will call a method named `Literal()` on the rule (if present). -- `phase` - either 1 for enter or 2 for exit. -- `args` - an array of arguments to pass into the visitor method of a rule. - -For example: - -```js -import { VisitNodeStep } from "@eslint/plugin-kit"; - -class MySourceCode { - traverse() { - const steps = []; - - for (const { node, parent, phase } of iterator(this.ast)) { - steps.push( - new VisitNodeStep({ - target: node, - phase: phase === "enter" ? 1 : 2, - args: [node, parent], - }), - ); - } - - return steps; - } -} -``` - -The `CallMethodStep` class is less common and is used to tell ESLint to call a specific method on the rule. The constructor accepts two arguments: - -- `target` - the name of the method to call, frequently beginning with `"on"` such as `"onCodePathStart"`. -- `args` - an array of arguments to pass to the method. - -For example: - -```js -import { VisitNodeStep, CallMethodStep } from "@eslint/plugin-kit"; - -class MySourceCode { - traverse() { - const steps = []; - - for (const { node, parent, phase } of iterator(this.ast)) { - steps.push( - new VisitNodeStep({ - target: node, - phase: phase === "enter" ? 1 : 2, - args: [node, parent], - }), - ); - - // call a method indicating how many times we've been through the loop - steps.push( - new CallMethodStep({ - target: "onIteration", - args: [steps.length] - }); - ) - } - - return steps; - } -} -``` - -### `Directive` - -The `Directive` class represents a disable directive in the source code and implements the `Directive` interface from `@eslint/core`. You can tell ESLint about disable directives using the `SourceCode#getDisableDirectives()` method, where part of the return value is an array of `Directive` objects. Here's an example: - -```js -import { Directive, ConfigCommentParser } from "@eslint/plugin-kit"; - -class MySourceCode { - getDisableDirectives() { - const directives = []; - const problems = []; - const commentParser = new ConfigCommentParser(); - - // read in the inline config nodes to check each one - this.getInlineConfigNodes().forEach(comment => { - // Step 1: Parse the directive - const { label, value, justification } = - commentParser.parseDirective(comment.value); - - // Step 2: Extract the directive value and create the `Directive` object - switch (label) { - case "eslint-disable": - case "eslint-enable": - case "eslint-disable-next-line": - case "eslint-disable-line": { - const directiveType = label.slice("eslint-".length); - - directives.push( - new Directive({ - type: directiveType, - node: comment, - value, - justification, - }), - ); - } - - // ignore any comments that don't begin with known labels - } - }); - - return { - directives, - problems, - }; - } -} -``` - -### `TextSourceCodeBase` - -The `TextSourceCodeBase` class is intended to be a base class that has several of the common members found in `SourceCode` objects already implemented. Those members are: - -- `lines` - an array of text lines that is created automatically when the constructor is called. -- `getLoc(nodeOrToken)` - gets the location of a node or token. Works for nodes that have the ESLint-style `loc` property and nodes that have the Unist-style [`position` property](https://github.com/syntax-tree/unist?tab=readme-ov-file#position). If you're using an AST with a different location format, you'll still need to implement this method yourself. -- `getLocFromIndex(index)` - Converts a source text index into a `{ line: number, column: number }` pair. (For this method to work, the root node should always cover the entire source code text, and the `getLoc()` method needs to be implemented correctly.) -- `getIndexFromLoc(loc)` - Converts a `{ line: number, column: number }` pair into a source text index. (For this method to work, the root node should always cover the entire source code text, and the `getLoc()` method needs to be implemented correctly.) -- `getRange(nodeOrToken)` - gets the range of a node or token within the source text. Works for nodes that have the ESLint-style `range` property and nodes that have the Unist-style [`position` property](https://github.com/syntax-tree/unist?tab=readme-ov-file#position). If you're using an AST with a different range format, you'll still need to implement this method yourself. -- `getText(node, beforeCount, afterCount)` - gets the source text for the given node that has range information attached. Optionally, can return additional characters before and after the given node. As long as `getRange()` is properly implemented, this method will just work. -- `getAncestors(node)` - returns the ancestry of the node. In order for this to work, you must implement the `getParent()` method yourself. - -Here's an example: - -```js -import { TextSourceCodeBase } from "@eslint/plugin-kit"; - -export class MySourceCode extends TextSourceCodeBase { - #parents = new Map(); - - constructor({ ast, text }) { - super({ ast, text }); - } - - getParent(node) { - return this.#parents.get(node); - } - - traverse() { - const steps = []; - - for (const { node, parent, phase } of iterator(this.ast)) { - //save the parent information - this.#parent.set(node, parent); - - steps.push( - new VisitNodeStep({ - target: node, - phase: phase === "enter" ? 1 : 2, - args: [node, parent], - }), - ); - } - - return steps; - } -} -``` - -In general, it's safe to collect the parent information during the `traverse()` method as `getParent()` and `getAncestor()` will only be called from rules once the AST has been traversed at least once. - -## License - -Apache 2.0 - - - - -## Sponsors - -The following companies, organizations, and individuals support ESLint's ongoing maintenance and development.

Zakas](https://humanwhocodes.com) - -If you find this useful, please consider supporting my work with a [donation](https://humanwhocodes.com/donate) or [nominate me](https://stars.github.com/nominate/) for a GitHub Star. - -## Description - -The core functionality for humanfs that is shared across all implementations for all runtimes. The contents of this package are intentionally runtime agnostic and are not intended to be used alone. - -Currently, this package simply exports the `Hfs` class, which is an abstract base class intended to be inherited from in runtime-specific hfs packages (like `@humanfs/node`). - -> [!WARNING] -> This project is **experimental** and may change significantly before v1.0.0. Use at your own caution and definitely not in production! - -## Installation - -### Node.js - -Install using your favorite package manager for Node.js: - -```shell -npm install @humanfs/core - -# or - -pnpm install @humanfs/core - -# or - -yarn add @humanfs/core - -# or - -bun install @humanfs/core -``` - -Then you can import the `Hfs` and `Path` classes like this: - -```js -import { Hfs, Path } from "@humanfs/core"; -``` - -### Deno - -Install using [JSR](https://jsr.io): - -```shell -deno add @humanfs/core - -# or - -jsr add @humanfs/core -``` - -Then you can import the `Hfs` class like this: - -```js -import { Hfs, Path } from "@humanfs/core"; -``` - -### Browser - -It's recommended to import the minified version to save bandwidth: - -```js -import { Hfs, Path } from "https://cdn.skypack.dev/@humanfs/core?min"; -``` - -However, you can also import the unminified version for debugging purposes: - -```js -import { Hfs, Path } from "https://cdn.skypack.dev/@humanfs/core"; -``` - -## Usage - -### `Hfs` Class - -The `Hfs` class contains all of the basic functionality for an `Hfs` instance *without* a predefined impl. This class is mostly used for creating runtime-specific impls, such as `NodeHfs` and `DenoHfs`. - -You can create your own instance by providing an `impl` directly: - -```js -const hfs = new Hfs({ impl: { async text() {} }}); -``` - -The specified `impl` becomes the base impl for the instance, meaning you can always reset back to it using `resetImpl()`. - -You can also inherit from `Hfs` to create your own class with a preconfigured impl, such as: - -```js -class MyHfs extends Hfs { - constructor() { - super({ - impl: myImpl - }); - } -} -``` - -### `Path` Class - -The `Path` class represents the path to a directory or file within a file system. It's an abstract representation that can be used even outside of traditional file systems where string paths might not make sense. - -```js -const myPath = new Path(["dir", "subdir"]); -console.log(myPath.toString()); // "dir/subdir" - -// add another step -myPath.push("file.txt"); -console.log(myPath.toString()); // "dir/subdir/file.txt" - -// get just the last step -console.log(myPath.name); // "file.txt" - -// change just the last step -myPath.name = "file.json"; -console.log(myPath.name); // "file.json" -console.log(myPath.toString()); // "dir/subdir/file.json" - -// get the size of the path -console.log(myPath.size); // 3 - -// remove the last step -myPath.pop(); -console.log(myPath.toString()); // "dir/subdir" - -// iterate over the steps -for (const step of myPath) { - // do something -} - -// create a new path from a string -const newPath = Path.fromString("/foo/bar"); -``` - -## License - -Apache 2.0 diff --git a/node_modules/@humanfs/core/dist/errors.d.ts b/node_modules/@humanfs/core/dist/errors.d.ts deleted file mode 100644 index c885bbf..0000000 --- a/node_modules/@humanfs/core/dist/errors.d.ts +++ /dev/null @@ -1,64 +0,0 @@ -/** - * @fileoverview Common error classes - * @author Nicholas C.

Zakas](https://humanwhocodes.com) - -If you find this useful, please consider supporting my work with a [donation](https://humanwhocodes.com/donate). - -## Description - -A utility for seamlessly importing modules in Node.js regardless if they are CommonJS or ESM format. Under the hood, this uses `import()` and relies on Node.js's CommonJS compatibility to work correctly. This ensures that the correct locations and formats are used for CommonJS so you can call one method and not worry about any compatibility issues. - -The problem with the default `import()` is that it always resolves relative to the file location in which it is called. If you want to resolve from a different location, you need to jump through a few hoops to achieve that. This package makes it easy to both resolve and import modules from any directory. - -## Usage - -### Node.js - -Install using [npm][npm] or [yarn][yarn]: - -``` -npm install @humanwhocodes/module-importer - -# or - -yarn add @humanwhocodes/module-importer -``` - -Import into your Node.js project: - -```js -// CommonJS -const { ModuleImporter } = require("@humanwhocodes/module-importer"); - -// ESM -import { ModuleImporter } from "@humanwhocodes/module-importer"; -``` - -### Bun - -Install using this command: - -``` -bun add @humanwhocodes/module-importer -``` - -Import into your Bun project: - -```js -import { ModuleImporter } from "@humanwhocodes/module-importer"; -``` - -## API - -After importing, create a new instance of `ModuleImporter` to start emitting events: - -```js -// cwd can be omitted to use process.cwd() -const importer = new ModuleImporter(cwd); - -// you can resolve the location of any package -const location = importer.resolve("./some-file.cjs"); - -// you can also import directly -const module = importer.import("./some-file.cjs"); -``` - -For both `resolve()` and `import()`, you can pass in package names and filenames. - -## Developer Setup - -1. Fork the repository -2. Clone your fork -3. Run `npm install` to setup dependencies -4.

This function should return `true` if you want the call retried and `false` if not. - -```js -// this instance will retry if the specific error code is found -const retrier = new Retrier(error => { - return error.code === "ENFILE" || error.code === "EMFILE"; -}); -``` - -Then, call the `retry()` method around the function you'd like to retry, such as: - -```js -import fs from "fs/promises"; - -const retrier = new Retrier(error => { - return error.code === "ENFILE" || error.code === "EMFILE"; -}); - -const text = await retrier.retry(() => fs.readFile("README.md", "utf8")); -``` - -The `retry()` method will either pass through the result on success or wait and retry on failure. Any error that isn't caught by the retrier is automatically rejected so the end result is a transparent passing through of both success and failure. - -### Setting a Timeout - -You can control how long a task will attempt to retry before giving up by passing the `timeout` option to the `Retrier` constructor. By default, the timeout is one minute. - -```js -import fs from "fs/promises"; - -const retrier = new Retrier(error => { - return error.code === "ENFILE" || error.code === "EMFILE"; -}, { timeout: 100_000 }); - -const text = await retrier.retry(() => fs.readFile("README.md", "utf8")); -``` - -When a call times out, it rejects the first error that was received from calling the function. - -### Setting a Concurrency Limit - -When processing a large number of function calls, you can limit the number of concurrent function calls by passing the `concurrency` option to the `Retrier` constructor. By default, `concurrency` is 1000. - -```js -import fs from "fs/promises"; - -const retrier = new Retrier(error => { - return error.code === "ENFILE" || error.code === "EMFILE"; -}, { concurrency: 100 }); - -const filenames = getFilenames(); -const contents = await Promise.all( - filenames.map(filename => retrier.retry(() => fs.readFile(filename, "utf8")) -); -``` - -### Aborting with `AbortSignal` - -You can also pass an `AbortSignal` to cancel a retry: - -```js -import fs from "fs/promises"; - -const controller = new AbortController(); -const retrier = new Retrier(error => { - return error.code === "ENFILE" || error.code === "EMFILE"; -}); - -const text = await retrier.retry( - () => fs.readFile("README.md", "utf8"), - { signal: controller.signal } -); -``` - -## Developer Setup - -1.

If you still want to opt-in to support of such constructions, you can pass the following option: ```javascript -acorn.Parser.extend(jsx({ allowNamespacedObjects: true })) +var ast = acorn.parse(code, { + plugins: { + jsx: { allowNamespacedObjects: true } + } +}); ``` Also, since most apps use pure React transformer, a new option was introduced that allows to prohibit namespaces completely: ```javascript -acorn.Parser.extend(jsx({ allowNamespaces: false })) +var ast = acorn.parse(code, { + plugins: { + jsx: { allowNamespaces: false } + } +});

+Make it possible to use `visit.ancestor` with a walk state. + +## 3.1.0 (2016-04-18) + +### Bug fixes + +Fix issue where the loose parser created invalid TemplateElement nodes +for unclosed template literals. + +Properly tokenize the division operator directly after a function +expression. + +Allow trailing comma in destructuring arrays. + +### New features + +The walker now allows defining handlers for `CatchClause` nodes. + +## 3.0.4 (2016-02-25) + +### Fixes + +Allow update expressions as left-hand-side of the ES7 exponential +operator. + +## 3.0.2 (2016-02-10) + +### Fixes + +Fix bug that accidentally made `undefined` a reserved word when +parsing ES7. + +## 3.0.0 (2016-02-10) + +### Breaking changes + +The default value of the `ecmaVersion` option is now 6 (used to be 5). +

For questions +and discussion, please use the +[Tern discussion forum](https://discuss.ternjs.net). + +## Installation + +The easiest way to install acorn is with [`npm`][npm]. + +[npm]: https://www.npmjs.com/ + +```sh +npm install acorn +``` + +Alternately, download the source. + +```sh +git clone https://github.com/ternjs/acorn.git +``` + +## Components + +When run in a CommonJS (node.js) or AMD environment, exported values +appear in the interfaces exposed by the individual files, as usual. +When loaded in the browser (Acorn works in any JS-enabled browser more +recent than IE5) without any kind of module management, a single +global object `acorn` will be defined, and all the exported properties +will be added to that. + +### Main parser + +This is implemented in `dist/acorn.js`, and is what you get when you +`require("acorn")` in node.js. + +**parse**`(input, options)` is used to parse a JavaScript program. +The `input` parameter is a string, `options` can be undefined or an +object setting some of the options listed below. The return value will +be an abstract syntax tree object as specified by the +[ESTree spec][estree]. + +When encountering a syntax error, the parser will raise a +`SyntaxError` object with a meaningful message. The error object will +have a `pos` property that indicates the character offset at which the +error occurred, and a `loc` object that contains a `{line, column}` +object referring to that same position. + +[estree]: https://github.com/estree/estree + +- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be + either 3, 5, 6, or 7. This influences support for strict mode, the set + of reserved words, and support for new syntax features. Default is 6. + + **NOTE**: Only 'stage 4' (finalized) ECMAScript 7 features are being + implemented by Acorn. That means that most of the draft standard is + not yet being parsed. + +- **sourceType**: Indicate the mode the code should be parsed in. Can be + either `"script"` or `"module"`. + +- **onInsertedSemicolon**: If given a callback, that callback will be + called whenever a missing semicolon is inserted by the parser. The + callback will be given the character offset of the point where the + semicolon is inserted as argument, and if `locations` is on, also a + `{line, column}` object representing this position. + +- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing + commas. + +- **allowReserved**: If `false`, using a reserved word will generate + an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher + versions. When given the value `"never"`, reserved words and + keywords can also not be used as property names (as in Internet + Explorer's old parser). + +- **allowReturnOutsideFunction**: By default, a return statement at + the top level raises an error. Set this to `true` to accept such + code. + +- **allowImportExportEverywhere**: By default, `import` and `export` + declarations can only appear at a program's top level. Setting this + option to `true` allows them anywhere where a statement is allowed. + +- **allowHashBang**: When this is enabled (off by default), if the + code starts with the characters `#!` (as in a shellscript), the + first line will be treated as a comment. + +- **locations**: When `true`, each node has a `loc` object attached + with `start` and `end` subobjects, each of which contains the + one-based line and zero-based column numbers in `{line, column}` + form. Default is `false`. + +- **onToken**: If a function is passed for this option, each found + token will be passed in same format as tokens returned from + `tokenizer().getToken()`. + + If array is passed, each found token is pushed to it. + + Note that you are not allowed to call the parser from the + callback—that will corrupt its internal state. + +- **onComment**: If a function is passed for this option, whenever a + comment is encountered the function will be called with the + following parameters: + + - `block`: `true` if the comment is a block comment, false if it + is a line comment. + - `text`: The content of the comment. + - `start`: Character offset of the start of the comment. + - `end`: Character offset of the end of the comment. + + When the `locations` options is on, the `{line, column}` locations + of the comment’s start and end are passed as two additional + parameters. + + If array is passed for this option, each found comment is pushed + to it as object in Esprima format: + + ```javascript + { + "type": "Line" | "Block", + "value": "comment text", + "start": Number, + "end": Number, + // If `locations` option is on: + "loc": { + "start": {line: Number, column: Number} + "end": {line: Number, column: Number} + }, + // If `ranges` option is on: + "range": [Number, Number] + } + ``` + + Note that you are not allowed to call the parser from the + callback—that will corrupt its internal state. + +- **ranges**: Nodes have their start and end characters offsets + recorded in `start` and `end` properties (directly on the node, + rather than the `loc` object, which holds line/column data. To also + add a [semi-standardized][range] `range` property holding a + `[start, end]` array with the same numbers, set the `ranges` option + to `true`. + +- **program**: It is possible to parse multiple files into a single + AST by passing the tree produced by parsing the first file as the + `program` option in subsequent parses. This will add the toplevel + forms of the parsed file to the "Program" (top) node of an existing + parse tree. + +- **sourceFile**: When the `locations` option is `true`, you can pass + this option to add a `source` attribute in every node’s `loc` + object. Note that the contents of this option are not examined or + processed in any way; you are free to use whatever format you + choose. + +- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property + will be added (regardless of the `location` option) directly to the + nodes, rather than the `loc` object. + +- **preserveParens**: If this option is `true`, parenthesized expressions + are represented by (non-standard) `ParenthesizedExpression` nodes + that have a single `expression` property containing the expression + inside parentheses. + +[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678 + +**parseExpressionAt**`(input, offset, options)` will parse a single +expression in a string, and return its AST. It will not complain if +there is more of the string left after the expression. + +**getLineInfo**`(input, offset)` can be used to get a `{line, +column}` object for a given program string and character offset. + +**tokenizer**`(input, options)` returns an object with a `getToken` +method that can be called repeatedly to get the next token, a `{start, +end, type, value}` object (with added `loc` property when the +`locations` option is enabled and `range` property when the `ranges` +option is enabled). When the token's type is `tokTypes.eof`, you +should stop calling the method, since it will keep returning that same +token forever. + +In ES6 environment, returned result can be used as any other +protocol-compliant iterable: + +```javascript +for (let token of acorn.tokenizer(str)) { + // iterate over the tokens +} + +// transform code to array of tokens: +var tokens = [...acorn.tokenizer(str)]; +``` + +**tokTypes** holds an object mapping names to the token type objects +that end up in the `type` properties of tokens. + +#### Note on using with [Escodegen][escodegen] + +Escodegen supports generating comments from AST, attached in +Esprima-specific format. In order to simulate same format in +Acorn, consider following example: + +```javascript +var comments = [], tokens = []; + +var ast = acorn.parse('var x = 42; // answer', { + // collect ranges for each node + ranges: true, + // collect comments in Esprima's format + onComment: comments, + // collect token ranges + onToken: tokens +}); + +// attach comments using collected information +escodegen.attachComments(ast, comments, tokens); + +// generate code +console.log(escodegen.generate(ast, {comment: true})); +// > 'var x = 42; // answer' +``` + +[escodegen]: https://github.com/estools/escodegen + +### dist/acorn_loose.js ### + +This file implements an error-tolerant parser. It exposes a single +function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`. + +**parse_dammit**`(input, options)` takes the same arguments and +returns the same syntax tree as the `parse` function in `acorn.js`, +but never raises an error, and will do its best to parse syntactically +invalid code in as meaningful a way as it can. It'll insert identifier +nodes with name `"✖"` as placeholders in places where it can't make +sense of the input. Depends on `acorn.js`, because it uses the same +tokenizer. + +### dist/walk.js ### + +Implements an abstract syntax tree walker. Will store its interface in +`acorn.walk` when loaded without a module system. + +**simple**`(node, visitors, base, state)` does a 'simple' walk over +a tree. `node` should be the AST node to walk, and `visitors` an +object with properties whose names correspond to node types in the +[ESTree spec][estree]. The properties should contain functions +that will be called with the node object and, if applicable the state +at that point. The last two arguments are optional. `base` is a walker +algorithm, and `state` is a start state. The default walker will +simply visit all statements and expressions and not produce a +meaningful state. (An example of a use of state is to track scope at +each point in the tree.) + +**ancestor**`(node, visitors, base, state)` does a 'simple' walk over +a tree, building up an array of ancestor nodes (including the current node) +and passing the array to the callbacks as a third parameter. + +**recursive**`(node, state, functions, base)` does a 'recursive' +walk, where the walker functions are responsible for continuing the +walk on the child nodes of their target node. `state` is the start +state, and `functions` should contain an object that maps node types +to walker functions. Such functions are called with `(node, state, c)` +arguments, and can cause the walk to continue on a sub-node by calling +the `c` argument on it with `(node, state)` arguments. The optional +`base` argument provides the fallback walker functions for node types +that aren't handled in the `functions` object. If not given, the +default walkers will be used. + +**make**`(functions, base)` builds a new walker object by using the +walker functions in `functions` and filling in the missing ones by +taking defaults from `base`. + +**findNodeAt**`(node, start, end, test, base, state)` tries to +locate a node in a tree at the given start and/or end offsets, which +satisfies the predicate `test`. `start` and `end` can be either `null` +(as wildcard) or a number. `test` may be a string (indicating a node +type) or a function that takes `(nodeType, node)` arguments and +returns a boolean indicating whether this node is interesting. `base` +and `state` are optional, and can be used to specify a custom walker. +Nodes are tested from inner to outer, so if two nodes match the +boundaries, the inner one will be preferred. + +**findNodeAround**`(node, pos, test, base, state)` is a lot like +`findNodeAt`, but will match any node that exists 'around' (spanning) +the given position. + +**findNodeAfter**`(node, pos, test, base, state)` is similar to +`findNodeAround`, but will match all nodes *after* the given position +(testing outer nodes before inner nodes). + +## Command line interface + +The `bin/acorn` utility can be used to parse a file from the command +line. It accepts as arguments its input file and the following +options: + +- `--ecma3|--ecma5|--ecma6|--ecma7`: Sets the ECMAScript version to parse. Default is + version 5. + +- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise. + +- `--locations`: Attaches a "loc" object to each node with "start" and + "end" subobjects, each of which contains the one-based line and + zero-based column numbers in `{line, column}` form. + +- `--allow-hash-bang`: If the code starts with the characters #! (as in a shellscript), the first line will be treated as a comment. + +- `--compact`: No whitespace is used in the AST output. + +- `--silent`: Do not output the AST, just return the exit status. + +- `--help`: Print the usage information and quit. + +The utility spits out the syntax tree as JSON data. + +## Build system + +Acorn is written in ECMAScript 6, as a set of small modules, in the +project's `src` directory, and compiled down to bigger ECMAScript 3 +files in `dist` using [Browserify](http://browserify.org) and +[Babel](http://babeljs.io/). If you are already using Babel, you can +consider including the modules directly. + +The command-line test runner (`npm test`) uses the ES6 modules. The +browser-based test page (`test/index.html`) uses the compiled modules. +The `bin/build-acorn.js` script builds the latter from the former. + +If you are working on Acorn, you'll probably want to try the code out +directly, without an intermediate build step. In your scripts, you can +register the Babel require shim like this: + + require("babel-core/register") + +That will allow you to directly `require` the ES6 modules. + +## Plugins + +Acorn is designed support allow plugins which, within reasonable +bounds, redefine the way the parser works. Plugins can add new token +types and new tokenizer contexts (if necessary), and extend methods in +the parser object. This is not a clean, elegant API—using it requires +an understanding of Acorn's internals, and plugins are likely to break +whenever those internals are significantly changed. But still, it is +_possible_, in this way, to create parsers for JavaScript dialects +without forking all of Acorn. And in principle it is even possible to +combine such plugins, so that if you have, for example, a plugin for +parsing types and a plugin for parsing JSX-style XML literals, you +could load them both and parse code with both JSX tags and types. + +A plugin should register itself by adding a property to +`acorn.plugins`, which holds a function. Calling `acorn.parse`, a +`plugins` option can be passed, holding an object mapping plugin names +to configuration values (or just `true` for plugins that don't take +options). After the parser object has been created, the initialization +functions for the chosen plugins are called with `(parser, +configValue)` arguments. They are expected to use the `parser.extend` +method to extend parser methods. For example, the `readToken` method +could be extended like this: + +```javascript +parser.extend("readToken", function(nextMethod) { + return function(code) { + console.log("Reading a token!") + return nextMethod.call(this, code) + } +}) +``` + +The `nextMethod` argument passed to `extend`'s second argument is the +previous value of this method, and should usually be called through to +whenever the extended method does not handle the call itself. + +Similarly, the loose parser allows plugins to register themselves via +`acorn.pluginsLoose`. The extension mechanism is the same as for the +normal parser: + +```javascript +looseParser.extend("readToken", function(nextMethod) { + return function() { + console.log("Reading a token in the loose parser!") + return nextMethod.call(this) + } +}) +``` + +### Existing plugins + + - [`acorn-jsx`](https://github.com/RReverser/acorn-jsx): Parse [Facebook JSX syntax extensions](https://github.com/facebook/jsx) + - [`acorn-es7-plugin`](https://github.com/MatAtBread/acorn-es7-plugin/): Parse [async/await syntax proposal](https://github.com/tc39/ecmascript-asyncawait) + - [`acorn-object-spread`](https://github.com/UXtemple/acorn-object-spread): Parse [object spread syntax proposal](https://github.com/sebmarkbage/ecmascript-rest-spread) + - [`acorn-es7`](https://www.npmjs.com/package/acorn-es7): Parse [decorator syntax proposal](https://github.com/wycats/javascript-decorators) + - [`acorn-objj`](https://www.npmjs.com/package/acorn-objj): [Objective-J](http://www.cappuccino-project.org/learn/objective-j.html) language parser built as Acorn plugin diff --git a/node_modules/acorn-jsx/node_modules/acorn/bin/acorn b/node_modules/acorn-jsx/node_modules/acorn/bin/acorn new file mode 100755 index 0000000..cf4acd5 --- /dev/null +++ b/node_modules/acorn-jsx/node_modules/acorn/bin/acorn @@ -0,0 +1,65 @@ +#!/usr/bin/env node +'use strict'; + +var path = require('path'); +var fs = require('fs'); +var acorn = require('../dist/acorn.js'); + +var infile; +var forceFile; +var silent = false; +var compact = false; +var tokenize = false; +var options = {} + +function help(status) { + var print = (status == 0) ?

The primary method is `eslintScope.analyze()`, which takes two arguments: - -1. `ast` - the ESTree-compliant AST structure to analyze. -2. `options` (optional) - Options to adjust how the scope is analyzed, including: - * `ignoreEval` (default: `false`) - Set to `true` to ignore all `eval()` calls (which would normally create scopes). - * `nodejsScope` (default: `false`) - Set to `true` to create a top-level function scope needed for CommonJS evaluation. - * `impliedStrict` (default: `false`) - Set to `true` to evaluate the code in strict mode even outside of modules and without `"use strict"`. - * `ecmaVersion` (default: `5`) - The version of ECMAScript to use to evaluate the code. - * `sourceType` (default: `"script"`) - The type of JavaScript file to evaluate. Change to `"module"` for ECMAScript module code. - * `childVisitorKeys` (default: `null`) - An object with visitor key information (like [`eslint-visitor-keys`](https://github.com/eslint/js/tree/main/packages/eslint-visitor-keys)). Without this, `eslint-scope` finds child nodes to visit algorithmically. Providing this option is a performance enhancement. - * `fallback` (default: `"iteration"`) - The strategy to use when `childVisitorKeys` is not specified. May be a function. - * `jsx` (default: `false`) - Enables the tracking of JSX components as variable references. - Example: ```js -import * as eslintScope from 'eslint-scope'; -import * as espree from 'espree'; -import estraverse from 'estraverse'; - -const options = { - ecmaVersion: 2022, - sourceType: "module" -}; +var eslintScope = require('eslint-scope'); +var espree = require('espree'); +var estraverse = require('estraverse'); -const ast = espree.parse(code, { range: true, ...options }); -const scopeManager = eslintScope.analyze(ast, options); +var ast = espree.parse(code); +var scopeManager = eslintScope.analyze(ast); -const currentScope = scopeManager.acquire(ast); // global scope +var currentScope = scopeManager.acquire(ast); // global scope estraverse.traverse(ast, { - enter (node, parent) { + enter: function(node, parent) { // do stuff if (/Function/.test(node.type)) { currentScope = scopeManager.acquire(node); // get current function scope } }, - leave(node, parent) { + leave: function(node, parent) { if (/Function/.test(node.type)) { currentScope = currentScope.upper; // set to parent scope } @@ -74,101 +40,9 @@ estraverse.traverse(ast, { }); ``` -## API - -The following section describes the API for this package.

It manages all scopes in a given AST. - -#### Properties - -- `scopes` - An array of all scopes. -- `globalScope` - Reference to the global scope. - -#### Methods - -- **`acquire(node, inner)`** - Acquires the appropriate scope for a given node. - - `node` - The AST node to acquire the scope from. - - `inner` - Optional boolean. When `true`, returns the innermost scope, otherwise returns the outermost scope. Default is `false`. - - Returns: The acquired scope or `null` if no scope is found. - -- **`acquireAll(node)`** - Acquires all scopes for a given node. - - `node` - The AST node to acquire scopes from. - - Returns: An array of scopes or `undefined` if none are found. - -- **`release(node, inner)`** - Returns the upper scope for a given node. - - `node` - The AST node to release. - - `inner` - Optional boolean. When `true`, returns the innermost upper scope, otherwise returns the outermost upper scope. Default is `false`. - - Returns: The upper scope or `null` if no upper scope exists. - -- **`getDeclaredVariables(node)`** - Get variables that are declared by the node. - - `node` - The AST node to get declarations from. - - Returns: An array of variable objects declared by the node. If the node doesn't declare any variables, it returns an empty array. - -- **`isGlobalReturn()`** - Determines if the global return statement should be allowed. - - Returns: `true` if the global return is enabled. - -- **`isModule()`** - Checks if the code should be handled as an ECMAScript module. - - Returns: `true` if the sourceType is "module". - -- **`isImpliedStrict()`** - Checks if implied strict mode is enabled. - - Returns: `true` if implied strict mode is enabled. - -- **`isStrictModeSupported()`** - Checks if strict mode is supported based on ECMAScript version. - - Returns: `true` if the ECMAScript version supports strict mode. - -### Scope Objects - -Scopes returned by the ScopeManager methods have the following properties: - -- `type` - The type of scope (e.g., "function", "block", "global"). -- `variables` - Array of variables declared in this scope. -- `set` - A Map of variable names to Variable objects for variables declared in this scope. -- `references` - Array of references in this scope. -- `through` - Array of references in this scope and its child scopes that aren't resolved in this scope or its child scopes. -- `variableScope` - Reference to the closest variable scope. -- `upper` - Reference to the parent scope. -- `childScopes` - Array of child scopes. -- `block` - The AST node that created this scope. - -### GlobalScope - -The `GlobalScope` class is a specialized scope representing the global execution context. It extends the base `Scope` class with additional functionality for handling implicitly defined global variables. - -#### Properties - -- **`implicit`** - Tracks implicitly defined global variables (those used without declaration). - - `set` - A Map of variable names to Variable objects for implicitly defined globals. - - `variables` - Array of implicit global Variable objects. - - `left` - Array of References that need to be linked to the variable they refer to. - -### Variable Objects - -Each variable object has the following properties: - -- `name` - The variable name. -- `identifiers` - Array of identifier nodes declaring this variable. -- `references` - Array of references to this variable. -- `defs` - Array of definition objects for this variable. -- `scope` - The scope object where this variable is defined. - ## Contributing -Issues and pull requests will be triaged and responded to as quickly as possible.

In many ways, it is similar to JSLint and JSHint with a few exceptions: -- ESLint uses [Espree](https://github.com/eslint/js/tree/main/packages/espree) for JavaScript parsing. -- ESLint uses an AST to evaluate patterns in code. -- ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime. - -## Table of Contents - -1.

(If you are using an official Node.js distribution, SSL is always built in.) +Prerequisites: [Node.js](https://nodejs.org/en/) (>=4.x), npm version 2+. -You can install and configure ESLint using this command: +There are two ways to install ESLint: globally and locally. -```shell -npm init @eslint/config@latest -``` +### Local Installation and Usage -After that, you can run ESLint on any file or directory like this: +If you want to include ESLint as part of your project's build system, we recommend installing it locally. You can do so using npm: -```shell -npx eslint yourfile.js +``` +$ npm install eslint --save-dev ``` -### pnpm Installation - -To use ESLint with pnpm, we recommend setting up a `.npmrc` file with at least the following settings: +You should then setup a configuration file: -```text -auto-install-peers=true -node-linker=hoisted +``` +$ ./node_modules/.bin/eslint --init ``` -This ensures that pnpm installs dependencies in a way that is more compatible with npm and is less likely to produce errors. +After that, you can run ESLint on any file or directory like this: -## Configuration +``` +$ ./node_modules/.bin/eslint yourfile.js +``` + +Any plugins or shareable configs that you use must also be installed locally to work with a locally-installed ESLint. -You can configure rules in your `eslint.config.js` files as in this example: +### Global Installation and Usage -```js -import { defineConfig } from "eslint/config"; +If you want to make ESLint available to tools that run across all of your projects, we recommend installing ESLint globally. You can do so using npm: -export default defineConfig([ - { - files: ["**/*.js", "**/*.cjs", "**/*.mjs"], - rules: { - "prefer-const": "warn", - "no-constant-binary-expression": "error", - }, - }, -]); +``` +$ npm install -g eslint ``` -The names `"prefer-const"` and `"no-constant-binary-expression"` are the names of [rules](https://eslint.org/docs/rules) in ESLint. The first value is the error level of the rule and can be one of these values: +You should then setup a configuration file: -- `"off"` or `0` - turn the rule off -- `"warn"` or `1` - turn the rule on as a warning (doesn't affect exit code) -- `"error"` or `2` - turn the rule on as an error (exit code will be 1) +``` +$ eslint --init +``` -The three error levels allow you fine-grained control over how ESLint applies rules (for more configuration options and details, see the [configuration docs](https://eslint.org/docs/latest/use/configure)). +After that, you can run ESLint on any file or directory like this: -## Version Support +``` +$ eslint yourfile.js +``` -The ESLint team provides ongoing support for the current version and six months of limited support for the previous version. Limited support includes critical bug fixes, security issues, and compatibility issues only. +Any plugins or shareable configs that you use must also be installed globally to work with a globally-installed ESLint. -ESLint offers commercial support for both current and previous versions through our partners, [Tidelift][tidelift] and [HeroDevs][herodevs]. +**Note:** `eslint --init` is intended for setting up and configuring ESLint on a per-project basis and will perform a local installation of ESLint and its plugins in the directory in which it is run. If you prefer using a global installation of ESLint, any plugins used in your configuration must also be installed globally. -See [Version Support](https://eslint.org/version-support) for more details. +## Configuration -## Code of Conduct +After running `eslint --init`, you'll have a `.eslintrc` file in your directory. In it, you'll see some rules configured like this: -ESLint adheres to the [OpenJS Foundation Code of Conduct](https://eslint.org/conduct). +```json +{ + "rules": { + "semi": ["error", "always"], + "quotes": ["error", "double"] + } +} +``` -## Filing Issues +The names `"semi"` and `"quotes"` are the names of [rules](https://eslint.org/docs/rules) in ESLint. The first value is the error level of the rule and can be one of these values: -Before filing an issue, please be sure to read the guidelines for what you're reporting: +* `"off"` or `0` - turn the rule off +* `"warn"` or `1` - turn the rule on as a warning (doesn't affect exit code) +* `"error"` or `2` - turn the rule on as an error (exit code will be 1) -- [Bug Report](https://eslint.org/docs/latest/contribute/report-bugs) -- [Propose a New Rule](https://eslint.org/docs/latest/contribute/propose-new-rule) -- [Proposing a Rule Change](https://eslint.org/docs/latest/contribute/propose-rule-change) -- [Request a Change](https://eslint.org/docs/latest/contribute/request-change) +The three error levels allow you fine-grained control over how ESLint applies rules (for more configuration options and details, see the [configuration docs](https://eslint.org/docs/user-guide/configuring)). -## Frequently Asked Questions +## Sponsors -### Does ESLint support JSX? +* Site search ([eslint.org](https://eslint.org)) is sponsored by [Algolia](https://www.algolia.com) -Yes, ESLint natively supports parsing JSX syntax (this must be enabled in [configuration](https://eslint.org/docs/latest/use/configure)). Please note that supporting JSX syntax _is not_ the same as supporting React. React applies specific semantics to JSX syntax that ESLint doesn't recognize. We recommend using [eslint-plugin-react](https://www.npmjs.com/package/eslint-plugin-react) if you are using React and want React semantics. +## Team -### Does Prettier replace ESLint? +These folks keep the project moving and are resources for help. -No, ESLint and Prettier have different jobs: ESLint is a linter (looking for problematic patterns) and Prettier is a code formatter. Using both tools is common, refer to [Prettier's documentation](https://prettier.io/docs/en/install#eslint-and-other-linters) to learn how to configure them to work well with each other. +### Technical Steering Committee (TSC) -### What ECMAScript versions does ESLint support? +* Nicholas C.

You can set your desired ECMAScript syntax and other settings (like global variables) through [configuration](https://eslint.org/docs/latest/use/configure). +## Releases -### What about experimental features? +We have scheduled releases every two weeks on Friday or Saturday. -ESLint's parser only officially supports the latest final ECMAScript standard. We will make changes to core rules in order to avoid crashes on stage 3 ECMAScript syntax proposals (as long as they are implemented using the correct experimental ESTree syntax). We may make changes to core rules to better work with language extensions (such as JSX, Flow, and TypeScript) on a case-by-case basis. +## Code of Conduct -In other cases (including if rules need to warn on more or fewer cases due to new syntax, rather than just not crashing), we recommend you use other parsers and/or rule plugins. If you are using Babel, you can use [@babel/eslint-parser](https://www.npmjs.com/package/@babel/eslint-parser) and [@babel/eslint-plugin](https://www.npmjs.com/package/@babel/eslint-plugin) to use any option available in Babel. +ESLint adheres to the [JS Foundation Code of Conduct](https://js.foundation/community/code-of-conduct). -Once a language feature has been adopted into the ECMAScript standard (stage 4 according to the [TC39 process](https://tc39.github.io/process-document/)), we will accept issues and pull requests related to the new feature, subject to our [contributing guidelines](https://eslint.org/docs/latest/contribute). Until then, please use the appropriate parser and plugin(s) for your experimental feature. +## Filing Issues -### Which Node.js versions does ESLint support? +Before filing an issue, please be sure to read the guidelines for what you're reporting: -ESLint updates the supported Node.js versions with each major release of ESLint.

The most recent maintenance release of Node.js -1. The lowest minor version of the Node.js LTS release that includes the features the ESLint team wants to use. -1. The Node.js Current release +## Semantic Versioning Policy -ESLint is also expected to work with Node.js versions released after the Node.js Current release. +ESLint follows [semantic versioning](https://semver.org). However, due to the nature of ESLint as a code quality tool, it's not always clear when a minor or major version bump occurs. To help clarify this for everyone, we've defined the following semantic versioning policy for ESLint: -Refer to the [Quick Start Guide](https://eslint.org/docs/latest/use/getting-started#prerequisites) for the officially supported Node.js versions for a given ESLint release. +* Patch release (intended to not break your lint build) + * A bug fix in a rule that results in ESLint reporting fewer errors. + * A bug fix to the CLI or core (including formatters). + * Improvements to documentation. + * Non-user-facing changes such as refactoring code, adding, deleting, or modifying tests, and increasing test coverage. + * Re-releasing after a failed release (i.e., publishing a release that doesn't work for anyone). +* Minor release (might break your lint build) + * A bug fix in a rule that results in ESLint reporting more errors. + * A new rule is created. + * A new option to an existing rule that does not result in ESLint reporting more errors by default. + * An existing rule is deprecated. + * A new CLI capability is created. + * New capabilities to the public API are added (new classes, new methods, new arguments to existing methods, etc.). + * A new formatter is created. +* Major release (likely to break your lint build) + * `eslint:recommended` is updated. + * A new option to an existing rule that results in ESLint reporting more errors by default. + * An existing formatter is removed. + * Part of the public API is removed or changed in an incompatible way. + +According to our policy, any minor update may report more errors than the previous release (ex: from a bug fix). As such, we recommend using the tilde (`~`) in `package.json` e.g. `"eslint": "~3.1.0"` to guarantee the results of your builds. -### Where to ask for help? +## License -Open a [discussion](https://github.com/eslint/eslint/discussions) or stop by our [Discord server](https://eslint.org/chat). +[![FOSSA Status](https://app.fossa.io/api/projects/git%2Bhttps%3A%2F%2Fgithub.com%2Feslint%2Feslint.svg?type=large)](https://app.fossa.io/projects/git%2Bhttps%3A%2F%2Fgithub.com%2Feslint%2Feslint?ref=badge_large) -### Why doesn't ESLint lock dependency versions? +## Frequently Asked Questions -Lock files like `package-lock.json` are helpful for deployed applications. They ensure that dependencies are consistent between environments and across deployments. +### How is ESLint different from JSHint? -Packages like `eslint` that get published to the npm registry do not include lock files. `npm install eslint` as a user will respect version constraints in ESLint's `package.json`. ESLint and its dependencies will be included in the user's lock file if one exists, but ESLint's own lock file would not be used. +The most significant difference is that ESLint has pluggable linting rules. That means you can use the rules it comes with, or you can extend it with rules created by others or by yourself! -We intentionally don't lock dependency versions so that we have the latest compatible dependency versions in development and CI that our users get when installing ESLint in a project. +### How does ESLint performance compare to JSHint? -The Twilio blog has a [deeper dive](https://www.twilio.com/blog/lockfiles-nodejs) to learn more. +ESLint is slower than JSHint, usually 2-3x slower on a single file. This is because ESLint uses Espree to construct an AST before it can evaluate your code whereas JSHint evaluates your code as it's being parsed. The speed is also based on the number of rules you enable; the more rules you enable, the slower the process. -## Releases +Despite being slower, we believe that ESLint is fast enough to replace JSHint without causing significant pain. -We have scheduled releases every two weeks on Friday or Saturday. You can follow a [release issue](https://github.com/eslint/eslint/issues?q=is%3Aopen+is%3Aissue+label%3Arelease) for updates about the scheduling of any particular release. +### I heard ESLint is going to replace JSCS? -## Security Policy +Yes. Since we are solving the same problems, ESLint and JSCS teams have decided to join forces and work together in the development of ESLint instead of competing with each other. You can read more about this in both [ESLint](https://eslint.org/blog/2016/04/welcoming-jscs-to-eslint) and [JSCS](https://medium.com/@markelog/jscs-end-of-the-line-bc9bf0b3fdb2#.u76sx334n) announcements. -ESLint takes security seriously. We work hard to ensure that ESLint is safe for everyone and that security issues are addressed quickly and responsibly. Read the full [security policy](https://github.com/eslint/.github/blob/master/SECURITY.md). +### So, should I stop using JSCS and start using ESLint? -## Semantic Versioning Policy +Maybe, depending on how much you need it. [JSCS has reached end of life](https://eslint.org/blog/2016/07/jscs-end-of-life), but if it is working for you then there is no reason to move yet. We are still working to smooth the transition. You can see our progress [here](https://github.com/eslint/eslint/milestones/JSCS%20Compatibility). We’ll announce when all of the changes necessary to support JSCS users in ESLint are complete and will start encouraging JSCS users to switch to ESLint at that time. -ESLint follows [semantic versioning](https://semver.org). However, due to the nature of ESLint as a code quality tool, it's not always clear when a minor or major version bump occurs. To help clarify this for everyone, we've defined the following semantic versioning policy for ESLint: +If you are having issues with JSCS, you can try to move to ESLint.

See the [error handling document](ERROR-HANDLING.md) for more details. + +```js +fetch('https://domain.invalid/') + .catch(err => console.error(err)); +``` + +#### Handling client and server errors +It is common to create a helper function to check that the response contains no client (4xx) or server (5xx) error responses: + +```js +function checkStatus(res) { + if (res.ok) { // res.status >= 200 && res.status < 300 + return res; + } else { + throw MyCustomError(res.statusText); + } +} + +fetch('https://httpbin.org/status/400') + .then(checkStatus) + .then(res => console.log('will not get here...')) +``` + +## Advanced Usage + +#### Streams +The "Node.js way" is to use streams when possible: + +```js +fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png') + .then(res => { + const dest = fs.createWriteStream('./octocat.png'); + res.body.pipe(dest); + }); +``` + +In Node.js 14 you can also use async iterators to read `body`; however, be careful to catch +errors -- the longer a response runs, the more likely it is to encounter an error. + +```js +const fetch = require('node-fetch'); +const response = await fetch('https://httpbin.org/stream/3'); +try { + for await (const chunk of response.body) { + console.dir(JSON.parse(chunk.toString())); + } +} catch (err) { + console.error(err.stack); +} +``` + +In Node.js 12 you can also use async iterators to read `body`; however, async iterators with streams +did not mature until Node.js 14, so you need to do some extra work to ensure you handle errors +directly from the stream and wait on it response to fully close. + +```js +const fetch = require('node-fetch'); +const read = async body => { + let error; + body.on('error', err => { + error = err; + }); + for await (const chunk of body) { + console.dir(JSON.parse(chunk.toString())); + } + return new Promise((resolve, reject) => { + body.on('close', () => { + error ? reject(error) : resolve(); + }); + }); +}; +try { + const response = await fetch('https://httpbin.org/stream/3'); + await read(response.body); +} catch (err) { + console.error(err.stack); +} +``` + +#### Buffer +If you prefer to cache binary data in full, use buffer(). (NOTE: `buffer()` is a `node-fetch`-only API) + +```js +const fileType = require('file-type'); + +fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png') + .then(res => res.buffer()) + .then(buffer => fileType(buffer)) + .then(type => { /* ... */ }); +``` + +#### Accessing Headers and other Meta data +```js +fetch('https://github.com/') + .then(res => { + console.log(res.ok); + console.log(res.status); + console.log(res.statusText); + console.log(res.headers.raw()); + console.log(res.headers.get('content-type')); + }); +``` + +#### Extract Set-Cookie Header + +Unlike browsers, you can access raw `Set-Cookie` headers manually using `Headers.raw()`. This is a `node-fetch` only API. + +```js +fetch(url).then(res => { + // returns an array of values, instead of a string of comma-separated values + console.log(res.headers.raw()['set-cookie']); +}); +``` + +#### Post data using a file stream + +```js +const { createReadStream } = require('fs'); + +const stream = createReadStream('input.txt'); + +fetch('https://httpbin.org/post', { method: 'POST', body: stream }) + .then(res => res.json()) + .then(json => console.log(json)); +``` + +#### Post with form-data (detect multipart) + +```js +const FormData = require('form-data'); + +const form = new FormData(); +form.append('a', 1); + +fetch('https://httpbin.org/post', { method: 'POST', body: form }) + .then(res => res.json()) + .then(json => console.log(json)); + +// OR, using custom headers +// NOTE: getHeaders() is non-standard API + +const form = new FormData(); +form.append('a', 1); + +const options = { + method: 'POST', + body: form, + headers: form.getHeaders() +} + +fetch('https://httpbin.org/post', options) + .then(res => res.json()) + .then(json => console.log(json)); +``` + +#### Request cancellation with AbortSignal + +> NOTE: You may cancel streamed requests only on Node >= v8.0.0 + +You may cancel requests with `AbortController`. A suggested implementation is [`abort-controller`](https://www.npmjs.com/package/abort-controller). + +An example of timing out a request after 150ms could be achieved as the following: + +```js +import AbortController from 'abort-controller'; + +const controller = new AbortController(); +const timeout = setTimeout( + () => { controller.abort(); }, + 150, +); + +fetch(url, { signal: controller.signal }) + .then(res => res.json()) + .then( + data => { + useData(data) + }, + err => { + if (err.name === 'AbortError') { + // request was aborted + } + }, + ) + .finally(() => { + clearTimeout(timeout); + }); +``` + +See [test cases](https://github.com/bitinn/node-fetch/blob/master/test/test.js) for more examples. + + +## API + +### fetch(url[, options]) + +- `url` A string representing the URL for fetching +- `options` [Options](#fetch-options) for the HTTP(S) request +- Returns: Promise<[Response](#class-response)> + +Perform an HTTP(S) fetch. + +`url` should be an absolute url, such as `https://example.com/`.

Note that [this changed in Node.js 19](https://github.com/nodejs/node/blob/4267b92604ad78584244488e7f7508a690cb80d0/lib/_http_agent.js#L564) to have `keepalive` true by default. If you wish to enable `keepalive` in an earlier version of Node.js, you can override the agent as per the following code sample. + +In addition, the `agent` option accepts a function that returns `http`(s)`.Agent` instance given current [URL](https://nodejs.org/api/url.html), this is useful during a redirection chain across HTTP and HTTPS protocol. + +```js +const httpAgent = new http.Agent({ + keepAlive: true +}); +const httpsAgent = new https.Agent({ + keepAlive: true +}); + +const options = { + agent: function (_parsedURL) { + if (_parsedURL.protocol == 'http:') { + return httpAgent; + } else { + return httpsAgent; + } + } +} +``` + + +### Class: Request + +An HTTP(S) request containing information about URL, method, headers, and the body.

This is to ensure +that all members are given the opportunity to participate in all +membership decisions. If a WG member is unable to attend a meeting +where a planned membership decision is being made, then their consent +is assumed. + +No more than 1/3 of the WG members may be affiliated with the same +employer. If removal or resignation of a WG member, or a change of +employment by a WG member, creates a situation where more than 1/3 of +the WG membership shares an employer, then the situation must be +immediately remedied by the resignation or removal of one or more WG +members affiliated with the over-represented employer(s). + +### WG Meetings + +The WG meets occasionally on a Google Hangout On Air. A designated moderator +approved by the WG runs the meeting. Each meeting should be +published to YouTube. + +Items are added to the WG agenda that are considered contentious or +are modifications of governance, contribution policy, WG membership, +or release process. + +The intention of the agenda is not to approve or review all patches; +that should happen continuously on GitHub and be handled by the larger +group of Collaborators. + +Any community member or contributor can ask that something be added to +the next meeting's agenda by logging a GitHub Issue. Any Collaborator, +WG member or the moderator can add the item to the agenda by adding +the ***WG-agenda*** tag to the issue. + +Prior to each WG meeting the moderator will share the Agenda with +members of the WG. WG members can add any items they like to the +agenda at the beginning of each meeting. The moderator and the WG +cannot veto or remove items. + +The WG may invite persons or representatives from certain projects to +participate in a non-voting capacity. + +The moderator is responsible for summarizing the discussion of each +agenda item and sends it as a pull request after the meeting. + +### Consensus Seeking Process + +The WG follows a +[Consensus +Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making) +decision-making model. + +When an agenda item has appeared to reach a consensus the moderator +will ask "Does anyone object?" as a final call for dissent from the +consensus. + +If an agenda item cannot reach a consensus a WG member can call for +either a closing vote or a vote to table the issue to the next +meeting. The call for a vote must be seconded by a majority of the WG +or else the discussion will continue. Simple majority wins. + +Note that changes to WG membership require a majority consensus.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +'use strict'; + +module.exports = Transform; + +var Duplex = require('./_stream_duplex'); + +/**/ +var util = Object.create(require('core-util-is')); +util.inherits = require('inherits'); +/**/ + +util.inherits(Transform, Duplex); + +function afterTransform(er, data) { + var ts = this._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) { + return this.emit('error', new Error('write callback called multiple times')); + } + + ts.writechunk = null; + ts.writecb = null; + + if (data != null) // single equals check for both `null` and `undefined` + this.push(data); + + cb(er); + + var rs = this._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + this._read(rs.highWaterMark); + } +} + +function Transform(options) { + if (!(this instanceof Transform)) return new Transform(options); + + Duplex.call(this, options); + + this._transformState = { + afterTransform: afterTransform.bind(this), + needTransform: false, + transforming: false, + writecb: null, + writechunk: null, + writeencoding: null + }; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + if (options) { + if (typeof options.transform === 'function') this._transform = options.transform; + + if (typeof options.flush === 'function') this._flush = options.flush; + } + + // When the writable side finishes, then flush out anything remaining. + this.on('prefinish', prefinish); +} + +function prefinish() { + var _this = this; + + if (typeof this._flush === 'function') { + this._flush(function (er, data) { + done(_this, er, data); + }); + } else { + done(this, null, null); + } +} + +Transform.prototype.push = function (chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

[contributors](https://github.com/Reactive-Extensions/RxJS/wiki/Contributors). If you wish to contribute, check out our [style guide]((https://github.com/Reactive-Extensions/RxJS/tree/master/doc/contributing)). + +You can contribute by reviewing and sending feedback on code checkins, suggesting and trying out new features as they are implemented, submit bugs and help us verify fixes as they are checked in, as well as submit code fixes or code contributions of your own. Note that all code submissions will be rigorously reviewed and tested by the Rx Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source. + +## License ## + +Copyright (c) Microsoft Open Technologies, Inc.

The +difference is subtle but can be important when an application requires the +additional performance that `Buffer.allocUnsafe(size)` provides. + +### Class Method: Buffer.allocUnsafeSlow(size) + + +* `size` {Number} + +Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.

A zero-length Buffer will +be created if a `size` less than or equal to 0 is specified. + +The underlying memory for `Buffer` instances created in this way is *not +initialized*. The contents of the newly created `Buffer` are unknown and +*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such +`Buffer` instances to zeroes. + +When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances, +allocations under 4KB are, by default, sliced from a single pre-allocated +`Buffer`. This allows applications to avoid the garbage collection overhead of +creating many individually allocated Buffers. This approach improves both +performance and memory usage by eliminating the need to track and cleanup as +many `Persistent` objects. + +However, in the case where a developer may need to retain a small chunk of +memory from a pool for an indeterminate amount of time, it may be appropriate +to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then +copy out the relevant bits. + +```js +// need to keep around a few small chunks of memory +const store = []; + +socket.on('readable', () => { + const data = socket.read(); + // allocate for retained data + const sb = Buffer.allocUnsafeSlow(10); + // copy the data into the new allocation + data.copy(sb, 0, 0, 10); + store.push(sb); +}); +``` + +Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after* +a developer has observed undue memory retention in their applications. + +A `TypeError` will be thrown if `size` is not a number. + +### All the Rest + +The rest of the `Buffer` API is exactly the same as in node.js. +[See the docs](https://nodejs.org/api/buffer.html). + + +## Related links + +- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660) +- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4) + +## Why is `Buffer` unsafe? + +Today, the node.js `Buffer` constructor is overloaded to handle many different argument +types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.), +`ArrayBuffer`, and also `Number`. + +The API is optimized for convenience: you can throw any type at it, and it will try to do +what you want. + +Because the Buffer constructor is so powerful, you often see code like this: + +```js +// Convert UTF-8 strings to hex +function toHex (str) { + return new Buffer(str).toString('hex') +} +``` + +***But what happens if `toHex` is called with a `Number` argument?*** + +### Remote Memory Disclosure + +If an attacker can make your program call the `Buffer` constructor with a `Number` +argument, then they can make it allocate uninitialized memory from the node.js process. +This could potentially disclose TLS private keys, user data, or database passwords. + +When the `Buffer` constructor is passed a `Number` argument, it returns an +**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like +this, you **MUST** overwrite the contents before returning it to the user. + +From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size): + +> `new Buffer(size)` +> +> - `size` Number +> +> The underlying memory for `Buffer` instances created in this way is not initialized. +> **The contents of a newly created `Buffer` are unknown and could contain sensitive +> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes. + +(Emphasis our own.) + +Whenever the programmer intended to create an uninitialized `Buffer` you often see code +like this: + +```js +var buf = new Buffer(16) + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### Would this ever be a problem in real code? + +Yes. It's surprisingly common to forget to check the type of your variables in a +dynamically-typed language like JavaScript. + +Usually the consequences of assuming the wrong type is that your program crashes with an +uncaught exception. But the failure mode for forgetting to check the type of arguments to +the `Buffer` constructor is more catastrophic. + +Here's an example of a vulnerable service that takes a JSON payload and converts it to +hex: + +```js +// Take a JSON payload {str: "some string"} and convert it to hex +var server = http.createServer(function (req, res) { + var data = '' + req.setEncoding('utf8') + req.on('data', function (chunk) { + data += chunk + }) + req.on('end', function () { + var body = JSON.parse(data) + res.end(new Buffer(body.str).toString('hex')) + }) +}) + +server.listen(8080) +``` + +In this example, an http client just has to send: + +```json +{ + "str": 1000 +} +``` + +and it will get back 1,000 bytes of uninitialized memory from the server. + +This is a very serious bug. It's similar in severity to the +[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process +memory by remote attackers. + + +### Which real-world packages were vulnerable? + +#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) + +[Mathias Buus](https://github.com/mafintosh) and I +([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, +[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow +anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get +them to reveal 20 bytes at a time of uninitialized memory from the node.js process. + +Here's +[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) +that fixed it. We released a new fixed version, created a +[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all +vulnerable versions on npm so users will get a warning to upgrade to a newer version. + +#### [`ws`](https://www.npmjs.com/package/ws) + +That got us wondering if there were other vulnerable packages. Sure enough, within a short +period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the +most popular WebSocket implementation in node.js. + +If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as +expected, then uninitialized server memory would be disclosed to the remote peer. + +These were the vulnerable methods: + +```js +socket.send(number) +socket.ping(number) +socket.pong(number) +``` + +Here's a vulnerable socket server with some echo functionality: + +```js +server.on('connection', function (socket) { + socket.on('message', function (message) { + message = JSON.parse(message) + if (message.type === 'echo') { + socket.send(message.data) // send back the user's message + } + }) +}) +``` + +`socket.send(number)` called on the server, will disclose server memory. + +Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue +was fixed, with a more detailed explanation. Props to +[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the +[Node Security Project disclosure](https://nodesecurity.io/advisories/67). + + +### What's the solution? + +It's important that node.js offers a fast way to get memory otherwise performance-critical +applications would needlessly get a lot slower. + +But we need a better way to *signal our intent* as programmers. **When we want +uninitialized memory, we should request it explicitly.** + +Sensitive functionality should not be packed into a developer-friendly API that loosely +accepts many different types. This type of API encourages the lazy practice of passing +variables in without checking the type very carefully. + +#### A new API: `Buffer.allocUnsafe(number)` + +The functionality of creating buffers with uninitialized memory should be part of another +API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that +frequently gets user input of all sorts of different types passed into it. + +```js +var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! + +// Immediately overwrite the uninitialized buffer with data from another buffer +for (var i = 0; i < buf.length; i++) { + buf[i] = otherBuf[i] +} +``` + + +### How do we fix node.js core? + +We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as +`semver-major`) which defends against one case: + +```js +var str = 16 +new Buffer(str, 'utf8') +``` + +In this situation, it's implied that the programmer intended the first argument to be a +string, since they passed an encoding as a second argument. Today, node.js will allocate +uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not +what the programmer intended. + +But this is only a partial solution, since if the programmer does `new Buffer(variable)` +(without an `encoding` parameter) there's no way to know what they intended. If `variable` +is sometimes a number, then uninitialized memory will sometimes be returned. + +### What's the real long-term fix? + +We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when +we need uninitialized memory. But that would break 1000s of packages. + +~~We believe the best solution is to:~~ + +~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ + +~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ + +#### Update + +We now support adding three new APIs: + +- `Buffer.from(value)` - convert from any type to a buffer +- `Buffer.alloc(size)` - create a zero-filled buffer +- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size + +This solves the core problem that affected `ws` and `bittorrent-dht` which is +`Buffer(variable)` getting tricked into taking a number argument. + +This way, existing code continues working and the impact on the npm ecosystem will be +minimal. Over time, npm maintainers can migrate performance-critical code to use +`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. + + +### Conclusion + +We think there's a serious design issue with the `Buffer` API as it exists today. It +promotes insecure software by putting high-risk functionality into a convenient API +with friendly "developer ergonomics". + +This wasn't merely a theoretical exercise because we found the issue in some of the +most popular npm packages. + +Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of +`buffer`. + +```js +var Buffer = require('safe-buffer').Buffer +``` + +Eventually, we hope that node.js core can switch to this new, safer behavior. We believe +the impact on the ecosystem would be minimal since it's not a breaking change. +Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while +older, insecure packages would magically become safe from this attack vector. + + +## links + +- [Node.js PR: buffer: throw if both length and enc are passed](https://github.com/nodejs/node/pull/4514) +- [Node Security Project disclosure for `ws`](https://nodesecurity.io/advisories/67) +- [Node Security Project disclosure for`bittorrent-dht`](https://nodesecurity.io/advisories/68) + + +## credit + +The original issues in `bittorrent-dht` +([disclosure](https://nodesecurity.io/advisories/68)) and +`ws` ([disclosure](https://nodesecurity.io/advisories/67)) were discovered by +[Mathias Buus](https://github.com/mafintosh) and +[Feross Aboukhadijeh](http://feross.org/). + +Thanks to [Adam Baldwin](https://github.com/evilpacket) for helping disclose these issues +and for his work running the [Node Security Project](https://nodesecurity.io/). + +Thanks to [John Hiesey](https://github.com/jhiesey) for proofreading this README and +auditing the code. + + +## license + +MIT.

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional, but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. The +version `3.4.5` *would* satisfy the range, because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose for this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range matching +semantics. + +Second, a user who has opted into using a prerelease version has +clearly indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for the purpose of range +matching) by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any version satisfies) +* `1.x` := `>=1.0.0 <2.0.0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

All +options in this object are `false` by default. The options supported +are: + +- `loose` Be more forgiving about not-quite-valid semver strings. + (Any resulting output will always be 100% strict compliant, of + course.) For backwards compatibility reasons, if the `options` + argument is a boolean value instead of an object, it is interpreted + to be the `loose` param. +- `includePrerelease` Set to suppress the [default + behavior](https://github.com/npm/node-semver#prerelease-tags) of + excluding prerelease tagged versions from ranges unless they are + explicitly opted into. + +Strict-mode Comparators and Ranges will be strict about the SemVer +strings that they parse. + +* `valid(v)`: Return the parsed version, or null if it's not valid. +* `inc(v, release)`: Return the version incremented by the release + type (`major`, `premajor`, `minor`, `preminor`, `patch`, + `prepatch`, or `prerelease`), or null if it's not valid + * `premajor` in one call will bump the version up to the next major + version and down to a prerelease of that major version. + `preminor`, and `prepatch` work the same way. + * If called from a non-prerelease version, the `prerelease` will work the + same as `prepatch`. It increments the patch version, then makes a + prerelease. If the input version is already a prerelease it simply + increments it. +* `prerelease(v)`: Returns an array of prerelease components, or null + if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]` +* `major(v)`: Return the major version number. +* `minor(v)`: Return the minor version number. +* `patch(v)`: Return the patch version number. +* `intersects(r1, r2, loose)`: Return true if the two supplied ranges + or comparators intersect. +* `parse(v)`: Attempt to parse a string as a semantic version, returning either + a `SemVer` object or `null`. + +### Comparison + +* `gt(v1, v2)`: `v1 > v2` +* `gte(v1, v2)`: `v1 >= v2` +* `lt(v1, v2)`: `v1 < v2` +* `lte(v1, v2)`: `v1 <= v2` +* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent, + even if they're not the exact same string. You already know how to + compare strings. +* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`. +* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call + the corresponding function above. `"==="` and `"!=="` do simple + string comparison, but are included for completeness. Throws if an + invalid comparison string is provided. +* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if + `v2` is greater. Sorts in ascending order if passed to `Array.sort()`. +* `rcompare(v1, v2)`: The reverse of compare. Sorts an array of versions + in descending order when passed to `Array.sort()`. +* `diff(v1, v2)`: Returns difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Comparators + +* `intersects(comparator)`: Return true if the comparators intersect + +### Ranges + +* `validRange(range)`: Return the valid range or null if it's not valid +* `satisfies(version, range)`: Return true if the version satisfies the + range. +* `maxSatisfying(versions, range)`: Return the highest version in the list + that satisfies the range, or `null` if none of them do. +* `minSatisfying(versions, range)`: Return the lowest version in the list + that satisfies the range, or `null` if none of them do. +* `minVersion(range)`: Return the lowest version that can possibly match + the given range. +* `gtr(version, range)`: Return `true` if version is greater than all the + versions possible in the range. +* `ltr(version, range)`: Return `true` if version is less than all the + versions possible in the range. +* `outside(version, range, hilo)`: Return true if the version is outside + the bounds of the range in either the high or low direction. The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the ranges comparators intersect + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so the version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string, and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). diff --git a/node_modules/semver/bin/semver b/node_modules/semver/bin/semver new file mode 100755 index 0000000..801e77f --- /dev/null +++ b/node_modules/semver/bin/semver @@ -0,0 +1,160 @@ +#!/usr/bin/env node +// Standalone semver comparison program. +// Exits successfully and prints matching version(s) if +// any supplied version is valid and passes all tests. + +var argv = process.argv.slice(2) + +var versions = [] + +var range = [] + +var inc = null + +var version = require('../package.json').version + +var loose = false + +var includePrerelease = false + +var coerce = false + +var identifier + +var semver = require('../semver') + +var reverse = false + +var options = {} + +main() + +function main () { + if (!argv.length) return help() + while (argv.length) { + var a = argv.shift() + var indexOfEqualSign = a.indexOf('=') + if (indexOfEqualSign !== -1) { + a = a.slice(0, indexOfEqualSign) + argv.unshift(a.slice(indexOfEqualSign + 1)) + } + switch (a) { + case '-rv': case '-rev': case '--rev': case '--reverse': + reverse = true + break + case '-l': case '--loose': + loose = true + break + case '-p': case '--include-prerelease': + includePrerelease = true + break + case '-v': case '--version': + versions.push(argv.shift()) + break + case '-i': case '--inc': case '--increment': + switch (argv[0]) { + case 'major': case 'minor': case 'patch': case 'prerelease': + case 'premajor': case 'preminor': case 'prepatch': + inc = argv.shift() + break + default: + inc = 'patch' + break + } + break + case '--preid': + identifier = argv.shift() + break + case '-r': case '--range': + range.push(argv.shift()) + break + case '-c': case '--coerce': + coerce = true + break + case '-h': case '--help': case '-?': + return help() + default: + versions.push(a) + break + } + } + + var options = { loose: loose, includePrerelease: includePrerelease } + + versions = versions.map(function (v) { + return coerce ?

If not specified, arguments will be placed in the same order as the placeholders in the input string. +* An optional `+` sign that forces to preceed the result with a plus or minus sign on numeric values. By default, only the `-` sign is used on negative numbers. +* An optional padding specifier that says what character to use for padding (if specified). Possible values are `0` or any other character precedeed by a `'` (single quote). The default is to pad with *spaces*. +* An optional `-` sign, that causes sprintf to left-align the result of this placeholder. The default is to right-align the result. +* An optional number, that says how many characters the result should have. If the value to be returned is shorter than this number, the result will be padded. When used with the `j` (JSON) type specifier, the padding length specifies the tab size used for indentation. +* An optional precision modifier, consisting of a `.` (dot) followed by a number, that says how many digits should be displayed for floating point numbers. When used with the `g` type specifier, it specifies the number of significant digits. When used on a string, it causes the result to be truncated. +* A type specifier that can be any of: + * `%` — yields a literal `%` character + * `b` — yields an integer as a binary number + * `c` — yields an integer as the character with that ASCII value + * `d` or `i` — yields an integer as a signed decimal number + * `e` — yields a float using scientific notation + * `u` — yields an integer as an unsigned decimal number + * `f` — yields a float as is; see notes on precision above + * `g` — yields a float as is; see notes on precision above + * `o` — yields an integer as an octal number + * `s` — yields a string as is + * `x` — yields an integer as a hexadecimal number (lower-case) + * `X` — yields an integer as a hexadecimal number (upper-case) + * `j` — yields a JavaScript object or array as a JSON encoded string + +## JavaScript `vsprintf` +`vsprintf` is the same as `sprintf` except that it accepts an array of arguments, rather than a variable number of arguments: + + vsprintf("The first 4 letters of the english alphabet are: %s, %s, %s and %s", ["a", "b", "c", "d"]) + +## Argument swapping +You can also swap the arguments.

At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out. + + +## Maintainers + +- [Sindre Sorhus](https://github.com/sindresorhus) +- [Josh Junon](https://github.com/qix-) + + +## License + +MIT diff --git a/node_modules/string-width/node_modules/strip-ansi/index.js b/node_modules/string-width/node_modules/strip-ansi/index.js new file mode 100644 index 0000000..96e0292 --- /dev/null +++ b/node_modules/string-width/node_modules/strip-ansi/index.js @@ -0,0 +1,4 @@ +'use strict'; +const ansiRegex = require('ansi-regex'); + +module.exports = input => typeof input === 'string' ? input.replace(ansiRegex(), '') : input; diff --git a/node_modules/string-width/node_modules/strip-ansi/license b/node_modules/string-width/node_modules/strip-ansi/license new file mode 100644 index 0000000..e7af2f7 --- /dev/null +++ b/node_modules/string-width/node_modules/strip-ansi/license @@ -0,0 +1,9 @@ +MIT License + +Copyright (c) Sindre Sorhus (sindresorhus.com) + +Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
