lacbd

lacbd is a Python library written in Rust that implements the Aho Corasick algorithm for fast subsentence matching of many keywords against one string.

You can find the actual Rust library as nitros12/like-aho-corasick-but-different.

Features

• Supports arbitrary values associated with each keyword
• Operates on Unicode word bounds, rather than naïve substring matching
• Case insensitive
• 10× faster than an equivalent regex

None of the existing python libraries fit my needs.

License

This library is AGPLv3+ licensed. That may seem like an odd choice for a library. However, doing so ensures that users of this code must make their application open source, even if run as a service (such as in a Discord bot). If you want to use this to make proprietary software, look somewhere else.
