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 "[e-mail]" "[e-mail]"
}
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.
