[antlr-interest] Antwort: Single quote and MismatchedTokenException

[lars.vonwedel at bayertechnology.com]

Mmmh, seems like it the quote rule is competing with the string rule which 
has quotes as delimiters and expects another quote at the end of the 
string. Now that I have stripped a trailing \n at the end of the line to 
scan, it seems to work.

Regards,
Lars

[antlr-interest] Single quote and MismatchedTokenException







Hello, 

I have a lexer where a quote is defined as 

QUOTE        :        '\''; 

running some simple text through the lexer (just repeatedly calling 
NextToken) works fine. 

However, when I run that lexer as part of an application (a Visual Studio 
Language Service in fact), the line 

   Match( '\'' ); 

in the generated Lexer method mQUOTE() throws an 
Antlr.Runtime.MismatchedTokenException. 

Any ideas what goes wrong here and what I can try to solve that problem ? 

Freundliche Grüße / Best Regards
Lars
