Hi,

I create a grammar using XBlockExpression.
And I have own Formatter but I want to avoid my formatting rule to impact the text of XBlockExpression.
I want to keep it unchanged.

How can I do that?

Best wishes,
Oliver

Is it not supported, right?

Basically no, that is not supported. You would have to create rules that
allow a flexible amount of space/linebreaks for the particular positions
in your grammar where you want the formatter to "accept text as it is".

It may be possible to override how things are fed to the formatter and
flip the "preserveWhitespace" flag while feeding the formatter the
section you want to be verbatim. (One difficulty being when the
serializer has no INode's (i.e. no source text), in which case you must
provide a default formatting.

If you are bit adventurous you could try the formatter I developed for
cloudsmith/geppetto @ github where this would be easy to achieve as it
provides both rule driven (CSS like) formatting and semantic formatting.
