Editing the baseLanguage.mpr with MPS

Hi MPS team!

I'm trying to modify the baseLanguage itself and build my own custom MPS from sources.

I tried to simply open the MPS_SRC/baseLanguage/baseLanguage/baseLanguage.mpr project in MPS, but it works not the way I expected - the baseLanguage language is still marked as (packaged), I get some NPE's while trying to regenerate the language, plus wrong paths errors and so on. I guess I'm not doing it right.

I wonder how do you edit the baseLanguage itself?

Best wishes,

Alexander.

Hello Alexander

You can start MPS from souces.

Open MPS.ipr file in Intellij Idea and start MPSLaucher run configuration.

Then you can edit any language in sources.
