I wish the resolution be better but Sebastien's comments are quite insightful and enjoyable.

Check it out! The latest build is available here.

P.S. In addition to my Russian blog here. I have an English blog on MPS here. I will mostly write to it because wordpress provides spam protection and has better interface than movable type.

It is about two weeks since previous build and we are planning to fire fresh builds more often then before: on bi-weekly basis or about that.

The second good news is that MPS bug-tracker is now open for external submitters. (I repeat myself but can’t help mentioning that the JetBrains bug tracker is developed using MPS).

I also would like to thank Tracy Snell for composing of updated Getting Started with MPS tutorial.

It is actually first ever external contribution to the MPS project!

http://www.jetbrains.net/confluence/display/MPS/JetBrains+MPS+Download+Page

The most important new features:


  • It's possible to work with MPS without IntelliJ IDEA

  • Generator tracer: easy way to find out why generator behaves this way.

  • Improved transient models saving

  • Unified DotExpression across the languages.

  • Ability to write Intentions

  • Ability to write custom Find Usages

  • Ability to write plugins from MPS

  • Logable refactoring language: it's possible to define refactorings which will be written to a log and replayed later

  • Improved editor UI: inspector now behaves in a different way

  • New example: language for complex numbers support

]]> Konstantin Solomatov 2008-03-27T18:10:53+03:00 The first real life LOP application! http://www.sergeydmitriev.com/mps/blog/archives/2008/03/the_first_real.html Today TeamCity project migrated to a new bug tracker system. TeamCity is an amazing product and Jolt finalist in Collaboration/Project Management tools categories, but it is not the point.

This event is noteworthy because the bug tracking system the TeamCity project has migrated to (codename Charisma) is a product which is completely developed in MPS.
It is not a ‘Hello world’ kind. It is quite exquisite and capable web application which we have been using internally for a while and now it is available for external users.

Charisma is 100% developed using the language oriented approach and its deployment code is 100% generated. Really, it's the 200% LOP application!:)

The Charisma solution includes about 50 model files of total size about 10MB. Concurrently, the Charisma team created dozens of DSLs which cover all required problem domains from general domains like XML to more narrow ones like RSS to most specific like ‘user management’.

The Charisma development has also generated a great deal of feedback which led to vast improvements of MPS performance, UI and ‘language design’ languages (aka bootstrap languages). MPS is becoming a really great tool!

New features:


  • MPS modules reference each other by their fqname rather than by path relative to a reference file

  • Performance optimizations for large models

  • meet and join types in HELGINS

  • Language development is now possible almost without Java IDE. Only weaving rule context queries have to be written in Java
  • New Helgins typesystem. You can now write BaseLanguage code in helgins rules.
  • New introduction to MPS. You can read it online here or open it from help menu in MPS.

]]> Konstantin Solomatov 2007-01-09T18:53:04+03:00 External DSLs - easy http://www.sergeydmitriev.com/mps/blog/archives/2006/12/external_dsls_-.html After Martin Fowler's recent JAOO speech some people got impression that external DSLs will hardly get steam because they are to complex to develop, that they need parsers and hard to teach, learn and maintain.
I can't agree.
First of all, mentioning of parsers is not relevant if we are talking about MPS. We don't use parsers technology.
Second, learning of new language is easy because of the tool support and because DSL expresses concepts of target domain better then GPL.
And last but not least, process of creation of a DSL (in MPS) is highly iterative (because of constant feedback) and much more funny then, say, development of an API using GPL.

Happy New Year to everybody!

]]> Igor Alshannikov 2006-12-20T19:51:46+03:00 90 minutes' DSL challenge! http://www.sergeydmitriev.com/mps/blog/archives/2006/12/90_minutes_dsl.html That must be interesting.
Famous Juha-Pekka Tolvanen is going to define a non-trivial DSL (20+ concepts with generator to working application) in just 90 minutes at his hands-on session.

He will bring MetaEdit with him but everybody is invited to bring his/her own tool.
I wonder if there is somebody out there who will bring MPS.
We can provide the latest build and 24/7 technical support:)

Since that I’ve got more experience in using of our collections language and can say that sometimes they DO offer improvements over Java, and may be even over C# collections.
I can show an example.
It is real description of custom auto-completion menu of one of the node editor’s cell.

In the 1st line I got all languages from input model (the 1st line is next to the "parameter objects : ...." caption).
In the 2nd line I got all structure-models from those languages.
And finally, in the 3d line I got all concepts declared in those structure-models.

Isn’t it beautiful?
