telescope-frecency.nvim

A telescope.nvim extension that offers intelligent prioritization when selecting files from your editing history.

Using an implementation of Mozilla's Frecency algorithm (used in Firefox's address bar), files edited frecently are given higher precedence in the list index.

As the extension learns your editing habits over time, the sorting of the list is dynamically altered to prioritize the files you're likely to need.

What about files that are neither ‘frequent’ or ‘recent’ ?

Frecency naturally works best for indexed files that have been given a reasonably high score.

New projects or rarely used files with generic names either don't get listed at all or can be buried under results with a higher score.

Frecency tackles this with Workspace Filters:

The workspace filter feature enables you to select from user defined filter tags that map to a directory or collection of directories. Filters are applied by entering :workspace_tag: anywhere in the query. Filter name completion is available by pressing <Tab> after the first : character.

When a filter is applied, results are reduced to entries whose path is a descendant of the workspace directory. The indexed results are optionally augmented with a listing of all files found in a recursive search of the workspace directory. Non-indexed files are given a score of zero and appear below the 'frecent' entries. When a non-indexed file is opened, it gains a score value and is available in future 'frecent' search results.

If the active buffer (prior to the finder being launched) is attached to an LSP server, an automatic LSP tag is available, which maps to the workspace directories provided by the language server.

Requirements

NOTE: fd or ripgrep will be used to list up workspace files. They are extremely faster than the native Lua logic. If you don't have them, it fallbacks to Lua code automatically.

Installation

This is an example for Lazy.nvim.

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

See :h telescope-frecency-configuration to know about further configurations.

Usage

:Telescope frecency
" Use a specific workspace tag:
:Telescope frecency workspace=CWD
" You can use with telescope's options
:Telescope frecency workspace=CWD path_display={"shorten"} theme=ivy

Filter tags are applied by typing the :tag: name (adding surrounding colons) in the finder query. Entering :<Tab> will trigger omni completion for available tags.
