Anybody got a simple SyntaxLanguage derived implementation?

Kelly,

I was in a similar position a little while back. See my post titled 'Questions on SimpleLanguage example' of 12 November 2006.

There is some helpful information in the resulting discussion. The biggest help to me though was that Actipro support shared code from their CSharpSyntaxLanguage implementation. That is what cracked the nut for me. I don't know if they plan to make it publicly available but why wouldn't they? I'm just a regular customer and it got me going. Should be part of the help.

Also note that the class NonMergableTokenBase that helps greatly has been lifted from CSharpSyntaxLanguage and is now in the core product. That is an important part of the puzzle.

Regrettably I can't share my end result as it is for a commercial product. It also isn't that easy to lift out a self-contained bit of code from what is a largish project.

Suffice to say I plugged away and with the CSharpSyntaxLanguage example it all fell into place for me pretty quickly.

Hang in there because the other side of the learning curve is a nice place to be.

Kelly,

I just emailed you the internal sample code we have for C# that Paul mentioned, which should definitely get you going. We'll try and improve the docs and code to include a low-level sample like this in the future.

But if anyone else would like to post samples, that would be wonderful too!

could I get some of that sample code too?

I never did get this working... I'm still using a mergeable non-dynamic language.

Any chance we'll get an example soon? Can the example have more than one lexical scope / state?

Hi Kelly,

We emailed you that C# sample a couple months ago. Did you get it?

Yes, I did. However, no matter what I did, I couldn't get it to work exactly the way I wanted it to. I'll see if I can set aside some time to give you an simple, but exact test case that has the same problems I was running into.

Mainly, I was having problems wherein the lexer could not recognize the final token in the document correctly. Even though the lexer was telling the "lexicalParseTarget" that the token was valid, the implementing class for lexicalParseTarget would not change the final token from an invalid token to the token I told it I found.

All that was before I even tried dealing with lexical contexts and stuff like that. This was just trying to get the lexer to work properly by itself.

I was just hoping you'd worked on a watered down example and fixed all the strange issues I was running into already ;)

Thanks,

Hi Kelly,

Yes if you wouldn't mind, emailing over a simple project showing the problem would be the best course of action here. Thanks!
