Generator using external compiler [message #1707223]

Hi!

The default Xtext generator implementation relies on our IGenarator to create files through IFileSystemAccess and provides in the background a lot of functionality like handling 'clean' builds and keeping track of already generated files.

We have a language that already has a toolset for compiling the sources. My generator just calls the compiler, but then we don't get the nice extra stuff from the builtins. I can't see a way to "hook" into that, except reading the generated file contents and recreating through IFileSystemAccess, which feels too much of a hack.

So I wonder if there is some other way to use the existing functionality of the generator, while letting the external compiler do the actual generation.

best regards,
Vlad

Hi,

can you elaborate a bit more on your external compiler?
of course you could simply call it (parameterized) from your IGenerator or IXtextBuilderParticipant

Hi,

Yes, it's not a problem to call it and it works fine. The issue is that if I create the output files via IFileSystemAccess, I get help with things that otherwise I need to implement myself: keep track of generated files to clean up when required, keep track of resource change history, handle output configurations, etc. It would be nice and helpful if I could use the existing implementation. I can't see a way, but that doesn't mean it doesn't exist Smile

And your compiler has no interface that acceps a stream or something like that?

No, it's a python script. It also generates multiple files, so it's not very easy to just make it output to stdout. I already have asked the respective developers, but I thought I'd try to see if there was another way.
