Introduction

As a Neovim user, you might be familiar with the Telescope plugin, which provides an efficient way to search and navigate through your files. One of its powerful features is the live_grep function, which allows you to search for a pattern in your files using Ripgrep, a fast and efficient search tool. However, by default, Telescope's live_grep function uses the default Ripgrep command, which might not be suitable for all use cases. In this article, we will explore how to pass a custom glob to Ripgrep when using Telescope's live_grep function.

Understanding Telescope's live_grep

Telescope's live_grep function is a powerful tool that allows you to search for a pattern in your files using Ripgrep. By default, it uses the following command:

rg --vimgrep --no-heading --no-line-number --column --smart-case --hidden --follow --no-ignore-vcs-ignores --no-ignore {query}

This command is a combination of various Ripgrep options that are optimized for Neovim's :grep command. However, you might want to customize this command to suit your specific needs.

Using the find_command argument

One way to customize Telescope's live_grep function is to use the find_command argument. This argument allows you to pass a list of arguments that will be used to construct the Ripgrep command. By default, Telescope's live_grep function uses the following find_command:

local telescope = require('telescope.builtin')
local find_command = telescope.find_command('live_grep', {
  find_command = { 'rg', '--vimgrep', '--no-heading', '--no-line-number', '--column', '--smart-case', '--hidden', '--follow', '--no-ignore-vcs-ignores', '--no-ignore' },
  initial_mode = 'insert',
  selection_caret = '^',
  selection_strategy = 'reset',
  sorting_strategy = 'ascending',
  layout_strategy = 'horizontal',
  layout_config = {
    horizontal = {
      prompt_position = 'top',
      preview_width = 0.5,
      results_width = 0.5,
    },
  },
  border = 'rounded',
  borderchars = { '─', '│', '─', '│', '╭', '╮', '╯', '╰' },
  color_devicons = true,
  path_display = 'smart',
  win_config = {
    border = 'rounded',
    borderchars = { '─', '│', '─', '│', '╭', '╮', '╯', '╰' },
    results_height = 10,
    preview_height = 10,
  },
  mappings = {
    i = {
      ['<C-u>'] = false,
      ['<C-d>'] = false,
    },
    n = {
      ['j'] = false,
      ['k'] = false,
      ['l'] = false,
      ['h'] = false,
    },
  },
})

As you can see, the find_command argument is a list of arguments that are used to construct the Ripgrep command. You can customize this list to suit your specific needs.

Passing a custom glob to Ripgrep

To pass a custom glob to Ripgrep, you can modify the find_command argument to include the glob pattern. For example, let's say you want to search for files that match the glob pattern *.txt:

local telescope = require('telescope.builtin')
local find_command = telescope.find_command('live_grep', {
  find_command = { 'rg', '--vimgrep', '--no-heading', '--no-line-number', '--column', '--smart-case', '--hidden', '--follow', '--no-ignore-vcs-ignores', '--no-ignore', '--glob', '*.txt' },
  initial_mode = 'insert',
  selection_caret = '^',
  selection_strategy = 'reset',
  sorting_strategy = 'ascending',
  layout_strategy = 'horizontal',
  layout_config = {
    horizontal = {
      prompt_position = 'top',
      preview_width = 0.5,
      results_width = 0.5,
    },
  },
  border = 'rounded',
  borderchars = { '─', '│', '─', '│', '╭', '╮', '╯', '╰' },
  color_devicons = true,
  path_display = 'smart',
  win_config = {
    border = 'rounded',
    borderchars = { '─', '│', '─', '│', '╭', '╮', '╯', '╰' },
    results_height = 10,
    preview_height = 10,
  },
  mappings = {
    i = {
      ['<C-u>'] = false,
      ['<C-d>'] = false,
    },
    n = {
      ['j'] = false,
      ['k'] = false,
      ['l'] = false,
      ['h'] = false,
    },
  },
})

In this example, we added the --glob option to the Ripgrep command, followed by the glob pattern *.txt. This will search for files that match the glob pattern *.txt.
