You must escape ( ...
[condition][]\(=(
But I'm not sure it will work, because expansion is doing nothing... I
mean, text before and after expansion is the same and the system was
designed to check for changes...
Do you need to have ( alone in a line? Can't you use a more textual
representation for "( or"? Like:
rule XYX
when
Either
Condition_1
Condition_2
End_Either
then
Action_1
end
So you can map Either to "( or" and End_either or whatever word you chose
to ")"?
Just trying to find alternate ways.

This doesn't work. :(
Acutally I am using the eclipse plugin and the DSL viewer shows that
the source code looks fine. The code I put in my first email was taken
from the DSL viewer.
but when I add the three lines:
[condition][](=(
[condition][])=)
[condition][]or=or
The DSL viewer refuses to work and shows the following msg:
DSL Rule Translation Error!
Reason:
java.util.regex.PatternSyntaxException: Unclosed group near index 13
(\W|^)((\W|$)
I think it means "(" in the last word.
I also tried "("="(", and '(', didn't work either.
So I can't add the three mappings this way. Any ideas? Thanks!
