telescope-frecency.nvim

An implementation of Mozillas Frecency algorithm for telescope.nvim.

Frecency: sorting by "frequency" and "recency"

Frecency is a score given to each unique file loaded into a Neovim buffer. On each load a timestamp is recorded to a database. The score is calculated using the age of each of the timestamps and the amount of times the file has been loaded:

Recency_score =

Timestamp age	Value
4 hours	100
1 day	80
3 days	60
1 week	40
1 month	20
90 days	10

final_score = frequency * recency_score / max_number_of_timestamps

WIP

TODO

• Implement sorter based on frecency score
• Check file entries are valid via async job on VimClose

Requirements

• telescope.nvim (required)
• sql.nvim (required)

Timestamps and file records are stored in an SQLite3 database for persistence and speed. This plugin uses sql.nvim to perform the database transactions.

Installation

TODO:

use {
  "sunjon/telescope-frecency",
  config = function()
    require"telescope".load_extension("frecency")
  end
}

Configuration

Function for keymaps

lua require("telescope").extensions.frecency.frecency(opts)
