Feature Request: Accept a custom prompt_parser

[zcag]

I would like to have the ability to provide a custom prompt_parser to further customize this plugin. It'll be extra nice if the parser can return some extra arguments to be passed on to vimgrep_args

Example Use case:

I want to just type what i want into the field and not think about quotes and globs and break the flow when I'm in the middle of debugging something.

Here's my test implementation of prompt_parser. Probably buggy and misses some corner cases but I used it on a whole day of work and it seemed fine.

I'll add the ability to escape / and starting - in the future.
Maybe we can have this kind of 'quoteless mode' as a feature on the plugin.

opts.prompt_parser = require('plugins.my-custom-prompt-parser')
require('telescope').extensions.live_grep_args.live_grep_args(opts)

-- plugins/my-custom-prompt-parser.lua
local M = {}

M.parse = function(prompt, _)
  local parts = ''
  local args = {}
  local path = nil

  path_index = prompt:find("/")

  if path_index then
    path_start_index = prompt:sub(0, path_index):find('%s[%S]*$')
    path_end_index = (prompt:find('%s', path_start_index+1) or 0)-1
    path = prompt:sub(path_start_index+1, path_end_index)
    if path:sub(-1) == '*' then path = path .. '/' end
    if path:sub(1, 1) == '/' then path = path:sub(2, -1)  end

    new_prompt = prompt:sub(0, path_start_index-1)
    if path_end_index ~= -1 then new_prompt = new_prompt .. prompt:sub(path_end_index+1, -1) end

    prompt = new_prompt
    table.insert(args, '--glob='.. path .. '**')
  end

  arg_index = prompt:find("%s%-")
  if arg_index then
    table.insert(args, prompt:sub(arg_index+1, -1))
    parts = prompt:sub(1, arg_index-1)
  else
    parts = prompt
  end

  return { args }, { parts }
end

return M

Example implementation:

I'm not sure if it's a good idea to do it like this, but just wanted to test the functionality, here's the PR: #52

Closing since we have a pr for this already #49
