Is it possible to create a workflow-like DSL with MPS?
As far as I understand JetBrains MPS is a tool for creation of DSLs. The DSL created with this tool can be absolutely different: it may contain some 'new' operators to extend classic Java, for example, or even some new graphical symbol to account for such an extension.
What I want is to create a DSL to account for building workflow.
I have heard Jetbrains professionals have completed this task for YouTrack workflows. May be I can check that somewhere?
May be, there is a tutorial on creating 'visual' DSLs in MPS?
May be, there are some examples of this?

Hi Dmitry,
yes, MPS is definitely capable of this. You may check out a video on the YouTrack workflow editor - https://www.youtube.com/watch?v=KDtxSYey-Eg
The "componentDependencies" sample project (bundled with MPS) illustrates the possibility to create graphical (i.e. diagrammatic) notations with MPS. The feature is described at https://confluence.jetbrains.com/display/MPSD20172/Diagramming+Editor
For learning MPS, I would recommend starting with the Fast Track at https://confluence.jetbrains.com/display/MPSD20172/Fast+Track+to+MPS

Thank you Vaclav!
I have started the tutorial, now looking at Kaja Project :)
Could you please clarify two points.
1. as far as I understand MPS generates Java code from DSL code. Where can I look at the code generated? For example, I want to check Kaja robots code, I mean real Java code to be ran on my machine.
2. Is it possible with MPS generate some other language than Java? For example, I want to 'extend' BRMS Rules, or XML, or something else? What do I need for this?
Hi Dmitry,
1. Right-click in the editor and choose "Preview generated text"
2. Yes, you can generate code in any language that you have installed in MPS. Java and XML come bundled, C and JavaScript are available as open-source projects.
