🚀 Features

• Added support for interpolating a standalone subroutine definition group via pattern. (#34)
• Interpolated regexes and patterns avoid adding a (?:…) wrapper in more cases when it's not needed.

• ./internals: Update plugin argument types.

This version's breaking changes don't affect direct use of the library, so they won't affect most users. The modified APIs are used by tools that build on top of Regex+.

🚨 Breaking

• Plugins: Expected return value changed from a string to an object with string property pattern.
• Plugins: Hidden capture indices are now explicitly provided/returned, rather than embedded via markers in the pattern.
• ./internals: Removed RegExpSubclass's undocumented support for capture transfer.
• ./internals: Removed emulationGroupMarker; markers are no longer used for hidden captures.
• rewrite: Renamed the returned expression property as pattern.

🚀 Features

• Improved performance of the subclass option, especially with long patterns that contain extended syntax.

🐞 Fixes

• Edge case fix for emulation-only capturing groups with transfer markers (for libraries that use Regex+ internals).

🚀 Features

• Export emulationGroupMarker in ./internals.
• Add support for emulation groups with capture transfer to RegExpSubclass.
  • Intended for use in libraries that build on Regex+ internals. This feature is undocumented and experimental.

🚀 Features

• Enables better tree shaking for ./internals.

🚀 Features

• Minor improvements for subclass types and error handling.
• Updated logo for new library name.

This library was renamed from just regex to Regex+, to make it easier to refer to the library and its regex flavor. The package and tag name remain regex as before, so this has no effect on code.

Version 5 is a minor update with small breaking changes that won't affect most people.

🚨 Breaking

• Type files (d.ts) were moved from ./types to ./dist/esm and ./dist/cjs.
• The undocumented ./atomic export added in v4.4.0 was renamed as ./internals.

🚀 Features

• RegExpSubclass was made available via ./internals.

🐞 Fixes

• Type resolution works correctly when using the library as CommonJS. (#29, @tao-cumplido)
• When using option subclass and flag d, resulting subpattern indices are adjusted to account for emulation groups.

🚀 Features

• Added ./atomic to exports, allowing direct use of the atomic and possessive plugins in other libraries.

🚀 Features

• When an invalid regex throws, always include the generated source and flags in the error message (some browsers automatically include them, but Firefox and Safari don't).

🐞 Fixes

• Convert numbers interpolated in enclosed \u{…} to hexadecimal. In other words, although interpolating a string like regex`\u{${'160'}}` returns /\u{160}/, interpolating the number regex`\u{${160}}` in this context returns /\u{A0}/. (#24, @graphemecluster)
