[news.eclipse.technology.imp] IMP LPG editor syntax errors on %options d

[Brian Payton <bpayton@xxxxxxxxxx>]

Hi,

I'm starting to use the IMP LPG source editor, and I noticed the editor 
shows syntax errors on certain input that LPG accepts, particularly in 
the %options declarations.  Here's the lines showing errors, plus the 
error messages.

Line:
  %options action=("DB2ZQueryParser.java", "/.", "./")
Error:
   Multiple messages: misplaced construct(s): "ERROR_TOKEN" {0} is 
invalid: "%options action" {0}
 expected after this token: "DISJOINTPREDECESSORSETS_KEY"

Line:
  %options ParseTable=%options ParseTable=lpg.lpgjavaruntime.ParseTable
(Note: this options line doesn't make much sense to me, so it might be 
an error in the source file.  However LPG doesn't complain about it.)
Error:
  Multiple messages: {0} unexpected token(s) ignored: "ERROR_TOKEN" {0} 
is invalid: "%options ParseTable=%options "

Line:
  %options var=nt,automatic_ast,visitor,parent_save
Error:
  {0} is invalid: "%options var"

Line:
  %options or_marker='|'
Error:
  {0} is invalid: "%options or_marker='"

I also noticed that the editor doesn't hilight as keywords the "no" 
prefix on keywords such as "noserialize", "nogoto_default", and 
"noerror-maps"
