[Xtext formatting] Ignore indentation in special cases and how to disable autowrap [message #730970]

Hi,
I created a formatter for my language definition by inheriting from AbstractDeclarativeFormatter. In the default generated formatter the following pattern is used for selecting pairs for indentation:

for( Pair<Keyword, Keyword> pair : f.findKeywordPairs( "{", "}" ) )

Is there a way to filter the result because I use also the curly brackets for array initialization.

I fixed this by introducing a terminal rule for the curly brackets and define the behaviour for each bracket occurence but when doing so I have to define it this way:

c.setLinewrap().after( f.get...().getOPEN_CURLY_BRACKETTerminalRuleCall_5() );
c.setIndentationDecrement().before(...
c.setIndentationDecrement().before(...

Thats ok, but when I make changes in my grammer definition, it is possible that the numbers at end changes which leads to compile errors.
Is there a better way?

Another question is how to disable the autowrap functionality in a global scope. The documentation says that it can be overridden for local elements. Isn't there a global setting?

Kind regards
Michael

Hi,

seems ok from my point. these compile errors are a feature and not a bug - consider having the same keyword more than once in a rule - and want to have different formatting rules. but afaik you dont need a own terminal rule

Hi,
as I already said it works great for me and only changes at the grammer could lead to compile errors and I hoped that there is a better way. Thanks for the reply.

Any ideas for the disabling of the autowrap functionaly?

Kind regards
Michael

Hi,

what do you mean with autowrap? linewrapping

c.setNoLinewrap();
does dont work globally

what about c.setAutoLinewrap(Integer.MAX_VALUE)

OK, also a solution but it also wraps after a big amount of tokens. A complete disabling would be better.
BTW. I tried it with a negative value which kills my runtime workspace (doesn't react any more).

Kind regards
Michael
