Sticky Regex Rewriter

A small transformer that rewrites sticky regex literals in JavaScript source code into equivalent constructor calls while leaving other expressions untouched.

Capabilities

Rewrites sticky regex literals

• Source containing /foo/y is emitted as new RegExp("foo", "y") in the transformed output. @test

Preserves combined flags

• Source containing /ab+c/gy is emitted as new RegExp("ab+c", "gy"), keeping both flags intact. @test

Leaves non-sticky regex unchanged

• Source containing /bar/g stays as the same regex literal in the output. @test

Ignores constructor usages

• Source using new RegExp("foo", "y") remains unchanged after transformation. @test
