Since the JetBrains MPS migration guide is not entirely exhaustive (or I couldn´t easily extract exhaustive information from it) about when it switches the JDK/JRE version it uses, here is a short list, at least from versions 2018.2 until 2023.2:
End of last year, itemis retired their https://projects.itemis.de/ server for JetBrains MPS usage. Instead, they introduced the https://artifacts.itemis.cloud/ server, which has a much nicer overview of all the downloadable opensource artifacts. Usually, when I want to get IETS3 (most of it for KernelF-purposes) artifacts, I can simply download everything through the dependency tree. The most … Read more
It has been a while since any updates, but this one is somewhat bigger. Today I have released a (very prototypical) first version of a MARTE (UML-Realtime) DSL. Since MARTE is based on the old and proven ROOM concepts, I hope that this DSL can be used and further developed into a good base for … Read more
While giving courses and helping colleagues, Eugen and me have noticed that it can be challenging to grasp the basic MPS project concepts and their relations. They are thoroughly explained by JetBrains here, but we often found ourselves drawing this diagram, so we decided to share it and hopefully help more people. The same holds … Read more
If you try to connect using the Cloud tool window of Modelix to a model repository that is served through a web server that has a custom SSL certifcate (something that would be typical to a company-internal webserver), then (at least at the moment of this writing), you will get an exception from the Modelix … Read more
Finally, I have finished editing the whitepaper on various debugging techniques in JetBrains MPS. Thanks go out to Sergej Koščejev for contributing to this whitepaper. You should also check out his complementary post at specificlanguages.com.
A brief update on how the artifacts of mbeddr, mbeddr.platform, and IETS3 have been changed (for the people that have to deal with older MPS models made using one of the mentioned extension packages): up until MPS 2019.2, it was possible to download all artifacts from build.mbeddr.com. Today, I was trying to do this as … Read more
Markus Völter has written a really nice Medium article about making the core of the functionality of a system (he states software system, but I think this can be generalized to system) where the domain is concerned explicit. He calls this embodiment of the accrued expertise of a company (or a person) Fachlichkeit. Since this … Read more
Let me tell you about something awesome that I have been working on with Mike Vlassiev from the JetBrains people (or rather, they have been working on it and I have done testing and provided feedback): the MPS Extensions (https://github.com/JetBrains/MPS-extensions) are now automatically made available on the JetBrains marketplace on every new MPS and MPS … Read more
Between MPS major versions, the MPS global caches are nicely separated (e.g. for MPS 2017.1, the cache directory is $HOME/.MPS2017.1 and for MPS 2017.2, the cache directory is $HOME/.MPS2017.2, where $HOME is your home directory, e.g. C:\Users\<yourusername> on Windows or /home/<yourusername> on Linux). Sometimes, there are reasons why you would want to change the cache … Read more
