[antlr-interest] second lexical pass

[idontwantanidwith2000init]

Is there an elegant way to do a second lexical path instead of 
writing two lexers?

For instance:
STRING_LITERAL:
'"' (~('\r'|'n'|'\\') | '\\' .) '"' ;

now STRING_LITERAL will colide with any special string you'd like to 
match, for instance:
DATE_TIME : '"'YYYY-MM-DD hh:mm:ss'"'

I've managed to merge it with: 
'"'(LETTER)*'"'
'"'(LETTER)*'.'(LETTER)*'"'
'"'(LETTER)*'-'(LETTER)*'"'
Which was a diffucult task but doable.


I thought about it and merging these rules is possible, but it will 
take me days to write it and we haven't talked about validation.
(It is a good to write down my thoughts I'm starting to convince 
myself that it is a good idea)

What do you think is a proper solution?

Tal.
