Shucker is a tracking-param filtering library, designed to strip URLs down to their canonical forms. It contains internally a set of rules derived from the AdguardFilters TrackParamFilter set, and then stripped down be able to be runnable outside of a browser. Note that although the original filters were designed for Javascript-based browser extensions, Shucker's core is a pure-Rust implementation for raw speed (some testing done against Hyperfine, but certainly seems fast enough so far i.e. < 1ms).
There is an example command line tool provided (cargo run --bin shuck <list of urls>) but the main usage will either be via the shucker::shuck fn, or the Python shucker library with shucker.shuck (which is mostly a thin wrapper over the Rust code), both of which take a URL and return a version of it without the ad-tracking.
make rebuild_rules will pull the latest upstream rules and rebuild.
The actual core Shucker code (i.e. everything except the external/adguardfilters folder) is licensed under the LGPL v3. However, the external/adguardfilters code is GPL v3 and as that is used as part of the build-time generation of Shucker currently, the overall library is therefore GPLv3. This might change in the future if we remove said build-time requirement though.
