SUBJECT: multiple lexer
I am wokring on a project to parse expressions which is part
of the doc. So I wrote a seperate parser for the expression.
And use multiple lexer. The problem I have is that when
switch back, one token is eaten from the expression parser.
Here is my doc syntax: main parser:
EXP { '1.2+3.5' T; '3.6+6.8' H;} So the main parser rule:
expression: EXP LCURLY ( SINGLE_QUOTE {
_selector.select("expressionLex"); expressionParser.Parse();
