Hi,

I want to write an xtext terminal rule for '&' which should have prefix and suffix.

Example: a&b

How to write terminal rule for it?

Did you read the Xtext Grammar documentation http://help.eclipse.org/mars/topic/org.eclipse.xtext.doc/contents/301_grammarlanguage.html?cp=85_2_0 already?
terminal XYZ:
  ('a'..'z'|'A'..'Z')+ '&' ('a'..'z'|'A'..'Z')+;

(assuming prefix and suffix can be any sequence of 1 or more letters)

Hi,

a=b&c or a=b &c or a = b & c

you dont allow spaces in your grammar? it it linebased? then you should consider rewriting the WS rule

Need professional support for Xtext, Xpand, EMF?
