Creating assembler language [message #644843]

Hi

I need some help with auto-complete and syntax coloring.

Cant get auto-complete to recognize my registers. When I hit control+space it offers %r but not the numbers.

About syntax coloring how to make registers and memory color different then st_w color. This is my first day with xtext so any help is welcome.

...

Data:
	Memory | Register ;
Store_Word:
	'st_w ' lo=Data ro=Data ; 
Register:
    GPR | SPR  ;

GPR:
	'%r' num=(NUM_0_7 | NUM_8_15 );

terminal NUM_0_7 returns ecore::EInt:
	'0'?('0'..'7');	

terminal NUM_8_15 returns ecore::EInt:
  '0'?('8'..'9') | '1'('0'..'5');

...

Hi,

there is no automatic code completion for non-standard terminal rules. You would manually implement the proposal rule for Register, GPR or SPR.

The highlighting you want will have to be done via semantic highlighting. There are forum entries, Xtext documentation and at least one blog post (if a bit outdated) http://blogs.itemis.de/stundzig/archives/467 that you may want to study.
