raven-table

Renders rows as an aligned text table. Columns size themselves to their widest cell, the header is bold, and short rows are padded out. It uses raven-color for the bold header.

Install

[dependencies]
"github.com/martian56/raven-table" = "v0.1.0"

That pulls in raven-color as well.

Usage

import "github.com/martian56/raven-table" { Table }

let t = Table.new(["Name", "Age", "City"])
t.row(["Alice", "30", "New York"])
t.row(["Bob", "25", "Boston"])
print(t.render())

which lays out as (the header bold, not shown here):

Name   Age  City
-----  ---  --------
Alice  30   New York
Bob    25   Boston

For a file or a pipe where you don't want the escape codes, build the table with .plain():

Table.new(["A", "B"]).plain()

How it works

Table.new(headers) starts a table, row(cells) adds a row (and returns the table, so you can chain the calls or not), and render() hands back the string. A short row leaves its missing cells blank, and no line ends with trailing whitespace.
