Generator Fails to Parse Regular Expressions #2

Open JCKortlang opened 3 months ago

JCKortlang commented 3 months ago

Generator fails to generate code when parsing regular expressions.

Specifically... PlotJs source code:

CSC : error CS8785: Generator 'JSInteropGenerator' failed to generate source. It will not contribute to the output and compilation errors may occur as a result. Exception was of type 'ParserException' with message 'Line 5655: Invalid regular expression'.

Problematic code:

    const reCombiner = /[\p{Combining_Mark}\p{Emoji_Modifier}]+/uy;
    const rePictographic = /\p{Extended_Pictographic}/uy;

Full stack trace by reproducing in unit tests.

Pulled this package locally and updated the underlying dependencies but the issue persists.

Opened an issue against Jint: https://github.com/sebastienros/jint/issues/1899

@JCKortlang Thanks for reporting this and the underlying issue, will get this fixed by end of week (currently out of country)
