NOTE: Regexes must be simple enough that they can be easily translated to JavaScript
|
|
RegExp syntax. In addition to JS-compatible syntax, the following features are available:
|
|
|
|
* Named groups will be converted to numbered groups automatically
|
|
* Inline-regex flags will be stripped, and where possible translated to RegExp-wide flags
