[antlr-interest] Java Target Generation Problem

[Jim Idle]

Actually it is because it thinks it is a documentation comment like Javadoc and you can only have one. The new parsres we are working on will give better error messages about such things.

 

If you used:

/* *****************

 

Then you won't get the issue - the lexer looks for /** at the comment start.

Hello,

 

ANTLR Version 3.2

Error -  Cannot generate the grammar because:

error(100) : ... : syntax error: antlr: ... : unexpected token: /************* comment 2 *********/

 

This is a very minor issue you could assign a priority of -1 to. Placing block comments in a grammar file with nothing between them will cause a generation error. e.g.

 

 

prog   :           test;

 

/******

 comment 1

******/

 

/*********

 comment 2

*********/

 

test     :           'a' ;
