Hi mjido,

formattingconfig.setWhitespaceRule(grammarAccess.getWSRule() );

While formatting, the formatter sometimes has to insert whitespaces into
the document. This tells which terminal rule would match them.

cheers,
Moritz

But when i define a terminal in my grammar like this:

terminal TwoSpaces:
' ';

and i do formattingconfig.setWhitespaceRule(grammarAccess.getTwoSpace sRule() );

It doesn't work why?

Hi Mjido,

the configured WhitespaceRule is expected to match any whitespace -
especially a single one. The default formatter implementation will
insert single whitespaces and cannot handly other configurations. Please
file a ticket and describe your usecase.

Regards,
Sebastian
