Amar Gurung commented on FREEMARKER-106:
----------------------------------------
Much appreciated.Thanks for the prompt reply Daniel. Use case is - I have a
bash script which has variables say for example to find length of an array
${#array[@]} and based on length do some validation. Also, it contains some
valid variables like ${X_a} etc.
I agree that variable references can't contain #. Could you please suggest me
some work around how to continue on exception.
I tried
cfg.setTemplateExceptionHandler(TemplateExceptionHandler.IGNORE_HANDLER); but
it's not working.
I'm short I want parser to continue parsing next sequence of tokens even if it
fails to parse some variable/token.
