Add Support for Pattern Searching Against Only File Names

[joeyagreco]

Is your feature request related to a problem? Please describe.

I love using this plugin like so:

keymap.set(
	"n",
	"<leader>fs",
	telescope.extensions.live_grep_args.live_grep_args,
	helpers.combine_tables(default_options, { desc = "search for words" })
)

This is great for searching for text inside files.

I would like something like this but for searching for files.

Currently I use this from telescope

keymap.set("n", "<leader>ff", telescope_builtin.find_files, helpers.combine_tables(default_options, { desc = "find files" }))

Which does not support ripgrep.

The feature I'm describing was best described here and the solution that I believe makes the most sense is here in the same thread.

Simply adding --files to a pattern does not give the required behavior.

Per rg -h

--files Print each file that would be searched.

The desired behavior is to Print each file where that file name matches the pattern given.

---

Describe the solution you'd like

Allow for prefixing a search with rg --files | rg so that the search returns filenames that match the pattern given, not filenames that contain matches for the pattern.

This could be in the form of a helper function similar to quote_prompt in telescope-live-grep-args.actions

Which would allow users to configure something like this

local live_grep_args_shortcuts = require("telescope-live-grep-args.shortcuts")
keymap.set("n", "<leader>ff", live_grep_args_shortcuts.grep_for_files)

Ideally, this would work just like telescope.extensions.live_grep_args.live_grep_args but with the above mentioned functionality of only applying the pattern search on file names and only returning file names.

---

Describe alternatives you've considered
I tried essentially recreating this plugin but for files using Telescope functions.

This was kind of a hassle but I was able to get it somewhat working.

Thanks!

I was not able to get --files to work with ripgrep inside live grep. So I came up with "" -g "//" -g "/*" -m1. The actual search happens with -g followed by -m1 to limit only 1 result for each file.
