Pomsky 0.12

Nov 10, 2025 - 7 min read

I am happy to announce version 0.12 of Pomsky, the next level regular expression language! Pomsky makes it easier than ever to write correct and maintainable regular expressions. Pomsky expressions are transpiled to regexes and can be used with many regex engines. This release comes packed with new features and improvements. Here are the highlights:

The RE2 flavor, used for Go’s regexp package, is now supported
Intersection of character sets
Improved Unicode support with Script Extensions
A convenient pomsky test subcommand for running unit tests
Powerful optimizations for repetitions, character sets, and alternatives
New IDE capabilities for the VSCode extension
New installers, including an npm package

With this release, we’re celebrating 1000 stars on GitHub! This is an important milestone, so I would like to take this opportunity to thank everyone who has supported me along the way: My siblings who always cheer me up, my colleague who gave me legal advice, everyone from the Rust community who provided useful feedback to me, the people who sent me pull requests, reported bugs, proposed new features, or reported vulnerabilities, and DALL·E for designing our logo. Thank you! Pomsky has a Discord server now. Stop by if you have a question, want to help, or just want to chat with the maintainers (currently only me) or other users!
