Hi All
I have a source code that is written in ANTLR V2. I want to migrate the code
from V2 to V3.
What are the procedures that needs to be followed? What all I need to
install?
Currently I am facing a problem with Comments.
When I instrument the code which is having comment , after instrumentation
all the comments are getting
removed.
I want to retain the comments after instrumentation of code.
The below is the grammar I am using in ANTLR v2.
// Single-line comments
SL_COMMENT
: "//" (~('\r'|'\n'))* {$setType(Token.SKIP);}
;
// multiple-line comments
ML_COMMENT
: "/*"
(options {generateAmbigWarnings=false;}:
{ LA(2)!='/' }? '*'
| EndOfLine
| ~('*'|'\n'|'\r')
)*
"*/" {$setType(Token.SKIP);}
;
if I use $Channel= HIDDEN instead of {$setType(Token.SKIP);}
it throws a error "Undefined token $"
I think this error could be because of using ANTLR 2
It would be nicer if the solution is in ANTLR 2 itslef.
I want to know how to retain comments in the instrumented code.
Vasanthi.
