Hi,

I'm working on a CSS-Grammer and while in most parts of the CSS-Syntax
the whitespace has no meaning in a certain area. I've for now turned off
the WS-hidden and added WS all over but that clutters my grammer and
makes less easy to read.

The grammer is found on my github repository [1] and the only area where
WS has a meaning is inside the selector-rule. I'd appreciate any
pointers on how to solve it.

Hi Tom,

you can use the hidden-clause per rule, e.g.

grammar org.mycompany.Lang with ..common.Terminals

Model:
name=QualifiedName
..
;

QualifiedName hidden():
ID ('.' ID)*
;

Did you try that?

Regards,
Sebastian

Hi Sebastian,

Sometimes it's just so easy. It works perfect.
