I changed the "language" to be CSharp2 and that fixed the illegal escape equence (thank youl) but now the following will not compile:
public ECMAScriptParser(ITokenStream input)
: this(input, new RecognizerSharedState()) {
}
public ECMAScriptParser(ITokenStream input, RecognizerSharedState state)
: base(input, state) {
InitializeCyclicDFAs();
}
It seems that RecognizerSharedState is no longer recognized. Any substitutes?
Thanks again.
