Inline comments:
In `@lua/fff/conf.lua`:
- Around line 376-380: Update M.preview_enabled to validate that config and
config.preview are tables before indexing, using vim.validate(). Ensure missing
preview.enabled defaults to true and the function always returns a boolean,
including for empty preview tables.
In `@lua/fff/core.lua`:
- Around line 100-107: Update change_indexing_directory to validate new_path as
a string with vim.validate() before calling vim.fn.expand(), while preserving
the existing empty-path notification and return behavior.
In `@lua/fff/layout.lua`:
- Around line 102-104: Update the preview_position validation in the exported
M.calculate_dimensions function to use vim.validate for user-provided input
instead of raising a direct error, or normalize invalid values to the existing
'right' fallback consistent with resolve_preview_position. Preserve valid left,
right, top, and bottom behavior.
In `@lua/fff/main.lua`:
- Line 212: Update M.change_indexing_directory to preserve its documented
boolean failure contract by catching failures when loading fff.core, including
unavailable fff.fuzzy or Rust backend dependencies, and returning false instead
of propagating the require error; retain the delegated change_indexing_directory
result on successful loading.
In `@lua/fff/picker_ui.lua`:
- Around line 2201-2208: When recreating file_info_win in the setup flow, apply
the same window-local options configured by M.setup_windows—including wrap,
cursorline, number, signcolumn, foldcolumn, and winhighlight—after
nvim_open_win, matching the open_preview initialization behavior and preserving
the hl.normal, hl.border, and hl.title highlights.
- Line 2461: Wrap the change_indexing_directory call in the base_path branch
with protected-call handling, matching the existing pcall behavior used by
fff.core’s DirChanged handler, so invalid paths do not propagate a traceback or
crash the picker.
- Around line 131-162: Make preview_config nil-safe in the cursorlineopt
resolution within open_preview by using the same optional-table contract as the
line-number expression. Preserve the existing default and validation behavior
when preview_config or cursorlineopt is absent.
In `@README.md`:
- Line 231: Update the min_list_height configuration comment to accurately state
that below the threshold the preview and file-info windows are hidden while the
prompt/input and list remain visible.
In `@tests/picker_ui_snap.lua`:
- Around line 103-105: Shorten the added comments in tests/picker_ui_snap.lua at
lines 103-105 and 192-195 so each is no more than two lines, preserving their
essential guidance about prompt-position coverage and scrollbar keys.

Neovim vim.fn.expand Lua non-string argument behavior vim.validate string
💡 Result:
In Neovim, vim.fn.expand is a wrapper around the Vimscript expand function [1][2]. When called from Lua, it expects its argument to be a string [2]. If you pass a non-string argument (such as nil, a number, or a table), Neovim will typically throw an error because the underlying Vimscript function cannot process the input [3][2]. While vim.fn.expand does not automatically validate its inputs using vim.validate, it is common practice to ensure that your arguments are strings before calling it, especially when dealing with dynamic values that might be nil [3][4]. To handle this safely and validate that a variable is a string in Lua, you can use vim.validate [5][6]: -- Example: Validating that 'path' is a string before passing to vim.fn.expand local path =... -- some variable vim.validate({ path = {path, 'string'} }) local expanded_path = vim.fn.expand(path) Key considerations: 1. Error Handling: vim.fn.expand can throw Vim errors (such as E348: No string under cursor or E944: Reverse range in character class) if the expansion fails or if the string contains characters interpreted as invalid patterns [4][7]. It is often robust to wrap such calls in pcall to prevent the entire Lua execution from aborting [8][4]. 2. vim.validate: This utility is specifically designed to check function parameters [5][6]. The standard form is vim.validate({name = {value, 'type'}}) [6]. Note that Neovim is moving toward a more streamlined form for vim.validate, but the 'string' type check remains a standard usage [9][6]. 3. Alternative: If you are simply checking for a string in your own code, standard Lua type(val) == 'string' is often sufficient unless you specifically need the error formatting provided by vim.validate [6].

error() in a public layout function will kill the picker.
M.calculate_dimensions is exported and receives config-derived values. A bad preview_position from a user function raises a hard error during create_ui. Use vim.validate or fall back to 'right', consistent with resolve_preview_position.
As per coding guidelines: "Use vim.validate() for validating user inputs in public functions".

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Recreated file-info window loses its window options.
M.setup_windows applies wrap, cursorline, number, signcolumn, foldcolumn and winhighlight to file_info_win. This branch opens a new window and skips all of them. After a resize that brings the panel back, it renders with default highlights instead of hl.normal / hl.border / hl.title. open_preview does this correctly; do the same here.
Proposed fix
M.state.file_info_win = vim.api.nvim_open_win(M.state.file_info_buf, false, win_configs.file_info)
+ local hl = M.state.config.hl
+ local win_hl = string.format('Normal:%s,FloatBorder:%s,FloatTitle:%s', hl.normal, hl.border, hl.title)
+ for opt, val in pairs({
+ wrap = false,
+ cursorline = false,
+ number = false,
+ relativenumber = false,
+ signcolumn = 'no',
+ foldcolumn = '0',
+ winhighlight = win_hl,
+ }) do
+ vim.api.nvim_set_option_value(opt, val, { win = M.state.file_info_win })
+ end📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Unprotected call. A bad base_path now throws a traceback.
The removed picker-local implementation notified the user on failure. This call has no pcall. fff.core's own DirChanged handler wraps the same function in pcall, so the failure mode is known. Do the same here.

Describe the threshold behavior accurately.
The layout hides the preview and file-info windows. It still renders the prompt/input and list. “Do not display anything except the list” is false.
