Hi eclipse.modeling.tmf group.
Sorry for yet a question but I am still struggling with using TCS with my
DSL.
In my sample file I have such a statement:
sharedVariables {?response, ?output}
But after doing a quick "Inject WSMO File to WSMO Model" and then "Extract
WSMO Model to WSMO File (.wsml)" it comes out like:
sharedVariables {"?response", "?output"}
I don't need or want these double-quotes on the output. I did have to add
a |'?' to the %protected ALPHA in the lexer to get it to recognize ? at
all within strings - and same for # which occurs in some of my strings. I
know I can just move ? to the syntax but this occurs elsewhere with other
symbols within the middle of strings so is a larger issue I need to
address.
For instance, I have some attributes with # in middle of the string (e.g.
dc#title or dc#contributor) and TCS also places double-quotes around those
strings on output.
Is there anything systematic I can do to stop this from occurring?

But I guess if I pass the <param name="identEsc" value=""/> parameter to
the extractor it would avoid using double-quotes on all strings, correct?
Even those for other attributes, some with spaces, where the double-quotes
are acceptable, or even necessary (and exist in the input samples)?
In my DSL, there are only two types of strings with this issue, the
examples are ?string (variable) and stringA#stringB (CompactURI), which I
need to treat as simple strings, where the show up, not to be delimited by
double-quotes. Basically, I'd prefer if TCS would consider ? and # as
just plain alpha characters in a string. Is there possibly a solution
using tokens?

Hi,
I see your point: the extractor should take into account the lexer.
Please, open a bug for this.
That being said, I believe your problem can be easily solved:
- Use stringSymbol for every string that must be quoted (you may need to
change the lexer so that double quotes are used for strings, and not for
identifiers).
- Use identifier for strings that must not be quoted, and pass <param
name="identEsc" value=""/> to the extractor.
Alternatively, you could extract the "?" from the identifier (as I
mentioned in my previous reply), and consider stringA#stringB as:
uri "#" fragment
with stringA and stringB in separate attributes.
Regards,
Frédéric Jouault

Thanks very much. I'll give that a try.
