Hi,
I would need your help to create a lexer for a simple templating language that would
eat up everything that is not between two dollars ($), but replaces two dollars to a
single dollar.
For example:
blabla$something$$$blabla$something2$bla$$bla
should be lexed as (blabla) (something) ($blabla) (something2) (bla$bla).
My lexer grammar is:
TEXT : ( ~('$') // Not dollar
| '$'! '$' // Or two dollars
)+ ;
DOLLAR : '$' ;
AntLR says:
warning: lexical nondeterminism between rules TEXT and DOLLAR upon
template.g: k==1:'$'
template.g: k==2:<end-of-token>
That I don't understand. If there is only a single $, it should be matched as DOLLAR of
course.
Thanks for your help.
