regexq
# Instead of writing: ^(?P<user>\w+)@(?P<domain>\w+)\.[a-zA-Z]{2,}$
# Write this:
$ regexq start named:user word end_named literal '@' named:domain word end_named literal '.' letters end
^(?P<user>\w+)@(?P<domain>\w+)\.[a-zA-Z]+$

Features

Built for developers who hate debugging regex

Every design decision optimizes for clarity and composability.

Blazingly Fast

Single Python file, zero dependencies. Instant regex generation with no startup cost.

Composable

Operations chain left to right, just like regex reads. Build complex patterns from simple parts.

Deterministic

Same input always produces the same regex. No AI, no guessing, no magic.

Zero Dependencies

Only Python 3.10+ standard library. Nothing to install, nothing to break.

Test Mode

Validate patterns against sample strings with --test. See matches and misses instantly.

Unix-Friendly

Outputs to stdout. Pipe to grep, sed, awk, or your clipboard. Fits any workflow.

Examples
