Hi,
I have an issue with antlrworks (1.4.2), where for a specific grammar,
it requires a whitespace.
I upgraded from antlrworks 1.1.7 where the same did not asked for the
whitespace.
example:
'?' string
| '%' string ':' percentage=INT
| ...
string : '"' LOWID '"';
LOWID : ('a'..'z'|'\-')+;
INT : ('0'..'9')+ ;
If I call my example rules with:
?\"acgt\"
it works fine
but if I call
%\"acgt\":30
If fails.
At least if I add a whitespace between % and \"acgt\", it works:
% \"acgt\":30
I really can't understand why a whitespace is required here, and only
here....
Thanks for your help
Olivier
