How to configure this plugin?

[ghillb]

Currently there doesn't seem to be a way to pass default parameters. For example one has to always type --hidden when searching in dotfiles. Also the rg flag -. (short for --hidden) does not work.

It would be nice, if this plugin could inherit the vim_grep_arguments setting from the default telescope live_grep function.

@ghillb funny thing, I was just migrating from builtin.live_grep to telescope-rgg.nvim and had the same problem. Couldn't find any docs but taking a look in the code I check there are some ways to do that. You can check the commit if you want, in any case here are some examples:

TLDR: One is to simply pass the new command in the option vimgrep_arguments like that:

:lua require('telescope').extensions.live_grep_raw.live_grep_raw({ vimgrep_arguments = { 'rg', '--hidden'} })

You can also create a function for it, and you can custom whatever you want, for example, you can set default values just like that:

local M = {}
function M.custom_live_grep_raw (opts)
  local defaults = {
    vimgrep_arguments = { 'rg', '--hidden'}
  }
  opts = vim.tbl_extend("force", defaults, opts or {})
  require('telescope').extensions.live_grep_raw.live_grep_raw(opts)
end
return M

And then you could call it by running something like:

:lua require'my.own_module'.custom_live_grep_raw()

As any other picker, you can also customize even more, like adding theme, custom path_display, layout_configs, and so on:

function M.live_grep_raw(opts)
  local defaults = {
    vimgrep_arguments = vim.split(M.vimgrep_arguments, ' '),
    path_display = M.my_custom_path_display,
    theme = 'dropdown',
  }
  opts = vim.tbl_extend("force", defaults, opts or {})
  opts = require("telescope.themes")["get_" .. opts.theme](opts)  -- Apply theme
  require("telescope").extensions.live_grep_raw.live_grep_raw(opts)
end

I also started a fork changing the plugin to make it possible to configure it through the common extension setup recipe. Soon I'll create a PR for this:

telescope.setup{
  extensions = {
    live_grep_raw = {
      vimgrep_arguments = {...}
    }
  }
}
telescope.load_extension('live_grep_raw')

Here is the PR #10

@alefpereira
Seems like a solid solution, but I tried both, the mapping:

vim.keymap.set({ "n", "v" }, "<c-a-p>", function()
  telescope.extensions.live_grep_raw.live_grep_raw({ vimgrep_arguments = { "rg", "--hidden" } })
end)

and the the config with your branch:

extensions = {
  live_grep_raw = {
    vimgrep_arguments = { "rg", "--hidden" },
  },
}

and both had the following effect:

[alefpereira]

I see, this behavior also happens with builtin.live_grep. This is because rg must have some options for it to output in correct format to be parsed. The "minimum" recommended command is the following:

{
  "rg",
  "--color=never",
  "--no-heading",
  "--with-filename",
  "--line-number",
  "--column",
  "--smart-case"
}

You can check vimgrep_arguments help more details:

:help vimgrep_arguments

I'll include this detail about vimgrep_arguments in the README.md pointing to the help, also going to change the examples to consider this.

live_grep_args now supports the additional_args arg (ha ha) 🙂 See #86 . You can pass args, that are not visible inside the prompt but forwarded to the grep command.
