c++ generation Follow

Now it isn't possible. But if you create a language, corresponding to C+, and text generation layer for C+, it will be possible. In short you should do following things:

1. Create a C++ corresponding language in the MPS.

2. For each its concept create a class ConceptName_TextGen, derived from jetbrains.mps.textGen.SNodeTextGen;.Method names are quite straightforward, and it I hope it's possible to do without looking for example. If not, ask us, and we provide several examples.

May be stupid question :-)

Konstatin, could you explain what does "create a class ConceptName_TextGen, derived from jetbrains.mps.textGen.SNodeTextGen" mean ?

What should I do to create it ?

take a look at this discussion

http://www.intellij.net/forums/thread.jspa?threadID=264893&tstart=0

you will find the complete example of simple 'target' language.

igor.

OK. Thank you!

But now I've got another problem with generators :-)

- I create concept of target language and mark it with one property macro

- Then I create mapping rule, write source query. Everything is still OK

- But when I try to select template, I press Ctrl+Space, select template but then I get such error messages:

*  ERROR - s.ide.command.CommandProcessor - Exception during executing command Unnamed

java.lang.RuntimeException: Couldn't set referent node: SimpleFunction [1167208921925] in sourceLang.gen

What's wrong ?

I've remade everything. And now it's OK !

fine! thax for letting us know

hi derUser, i am also be interested in c++ code generation. would you be willing to share your development?
