Non-Sticky Regex Pass-Through
A helper that compiles JavaScript source while applying a sticky-regex transform, ensuring regex literals without the y flag stay untouched.
Capabilities
Leaves plain regex unchanged
- Transforming
const re = /abc/;returns code that still contains/abc/;with no constructor wrapper. @test
Preserves other flags without stickiness
- Transforming
const re = /foo/gim;keeps the literal as-is, preserving its flags without wrapping it. @test
Converts sticky regex
- Transforming
const re = /bar/y;emits a constructor form that keeps the same pattern and includes theyflag. @test
