Hello all,
I want to generate c code from a dsl.
I can't find somewhere resources that shows a way to generate something following my
requirements which I will analyse in the following lines.

In the following lines I will give more informations:
Lets say that I have the following dsl program.
a; b; c; //three statements
and for those statements I want to generate an other program with the statements
A; B; C. And I want this file to have an extention ".c".
How can I do that?

What I sould write where the dots are?

override void doGenerate(Resource resource, IFileSystemAccess fsa) {
// fsa.generateFile(..........???????..............)

}

Thanks.

Hi I am not sure if I get your question.
I assume you don't use xbase.

Generating code is generating text. So it does not matter if you
generate a test.java or a test.c or a test.h file or whether these
files contain java or c or something else

Did you do the Xtext tutorials from the docs generating code? If you
need specific help you should at least share your grammar.
Regards Christian

Thanks.
Lets say that I want to generate text A;B;C in my example, which is independent of the original dsl code a;b;c
And I want to generate just one file (not many as in one example I have seen).
To do it more concrete lets say that I want to always generate the following peace of code
(*independent of what the dsl user have writen.)

#include <stdio.h>
int main() {
return 0;
}

How can I do it? If I knew that, I beleive that I could make a start.

Thanks a lot
Antonis.
