Generator Fails to Parse Regular Expressions #2

Closed JCKortlang closed 1 week ago

JCKortlang commented 5 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)

@JCKortlang Sorry took so long, got massively sidetracked, JInt upgraded to newish version that fixes this issue, v2.0 is out which also changes the way the .json file works, hope it makes sense.
