[Feature] how about add a feature for search content in the frecency files?

[cstsunfu]

Thanks for the good job. I have used this plugin long time and this is a pretty good plugin to find the recent files.

But sometimes I am not remember the file name but a string in the content. It is better for me to search the content in the recent files. I am not good at telescope, so I only write a ugly code to make it work at git commit 'a3e818d0', but when the plugin is update it does not work anymore. So could you provide this as a builtin feature? Thanks

Almost the same idea is issued on #125. I'm thinking an idea that I will introduce a “query” function to get entries from the DB.

local files = require("frecency").query {
  limit = 100,
  order_by = "score",
}

and this contains such as……

[
  "/path/to/foo.txt",
  "/more/path/to/bar.md",

  ……
  -- up to 100 files
]

Then your code can be shorten like this.

local frecency_file_path = require("frecency").query { …… }
local live_grepper = finders.new_job(function(prompt)
  if not prompt or prompt == "" then
    return nil
  end

  return vim.tbl_flatten({ args, "--", prompt, frecency_file_path })
end, make_entry.gen_from_vimgrep({}), 1000, "/")

pickers.new(……):find()

I see some people want to output entries from DB to use outside this plugin (#157), so this function can also be a solution for it.

How do you think this? Can this satisfy your purpose?

Yes, I think this is a great solution. This is very helpful for my issue, and this will used on many other purpose.

[delphinus]

I am still implementing #217 experimentally, but I can see it achieves your purpose with simple code.

(And I also found telescope's builtin live_grep picker accepts filenames to search.)

vim.keymap.set("n", "<Leader>tg", function()
  local frecency = require("telescope").extensions.frecency
  require("telescope.builtin").live_grep {
    -- HACK: `search_dirs` can accept files to grep nevertheless its name
    search_dirs = frecency.query {},
  }
end)

[delphinus]

I added query() to get entries from DB. Check it.

It works. Thanks for your awesome job.
