URL Eater

Clean unnecessary parameters from URLs copied to clipboard

Usage

Run with a filter file that specifies which parameters should be removed:

url-eater denylist.kdl

An example filter file:

category "Spotify" {
	params "context@open.spotify.com" "si@open.spotify.com"
}
category "Campaign tracking (itm)" {
	params "itm_*"
}
category "Campaign tracking (stm)" disabled=true {
	params "stm_*"
}

Categories are used to structure filter lists and allow disabling/enabling filters in groups. Each parameter applies to all URLs, unless a domain like @example.com is specified at the end. Both the parameter and the domain parts can contain wildcards. Use * to match 0 or more characters, and ? to match exactly one character.
The structure is based on NeatURL's format, with a few differences (aside from a different file format):

• Single character matching (?) is supported.
• $ and ! rules are currently unsupported.

The intended use case is running the program as a background service.

Usage example

This repository also contains a Nix flake. It can be used in a NixOS configuration like this:

1. Add flake to inputs:

url-eater.url = "github:AgathaSorceress/url-eater";
url-eater.inputs.nixpkgs.follows = "nixpkgs"; #optional

2. Adding output:

  outputs = inputs@{ self, nixpkgs, url-eater, ... }:

3. Import NixOS module

imports = [ url-eater.nixosModule ];

4. Configure the module:

{ ... }: {
  services.url-eater = {
    enable = true;
    filters = ''
      category "Spotify" {
      	params "context@open.spotify.com" "si@open.spotify.com"
      }
      category "Twitter" {
      	params "cxt@*.twitter.com" "ref_*@*.twitter.com" "s@*.twitter.com" "t@*.twitter.com" "twclid"
      }
    '';
  };
}
