Try the MPS 2017.2 EAP 3

MPS 2017.2 EAP3 is ready!

Sweet functions came in this EAP. Now you can specify matching text and in-editor textual presentation for references directly in the editor aspect. Your time is valuable, so type less and code more with our shiftless code completion.

We know that sometimes it is hard to track the action in the completion and context assistance, that’s why we implement a new way to visualize the trace in the project tool.

To see the complete list of new features go to What’s new in MPS 2017.2Bugs fixed.

If you have any question send us an email.

Plugin spotlight: Generate Python or Ruby with MPS-plaintextgen

The guys of DSLFoundry have brought my attention to the MPS-plaintextgen plugin recently. The plugin offers a language that models textual documents as collections of lines and words, supports layouts, alignment and indentation, and in addition to that, it comes with decent editing experience built in.

The binaries of the plugin can be obtained from the JetBrains plugin repository.

The language is primarily meant to be used in generators to ease transformation of complex models into text. Unlike with the TextGen aspect in MPS, the plaintextgen language allows you to leverage the model-to-model capabilities of the MPS Generator and enjoy the comfort of the projectional editor when defining the transformations. You simply model the output document and parametrize it with values from the input model.

This can be useful in several interesting ways:

  • generate textual documents from your models without the need for TextGen
  • quickly mock the generator for your prototype languages during development
  • generate code of limited complexity in general-purpose languages, for which MPS does not have support

As a proof-of-concept, I’ve created a sample project that uses the MPS plaintextgen language to generate Python and Ruby as well as plain text. You can check out the MultiLangEntities project on GitHub.

Releasing JetBrains MPS 2017.1

Today marks another milestone in the MPS history. MPS 2017.1 – the first release under a new version scheme, has just been released. We have loaded it with handy new features and useful enhancements:

  • HTTP support plugin lets you conveniently share urls to nodes and files
  • The generator plans have progressed nicely to give flexibility to your generation process
  • The migration to the new Transform Menu Language that defines side-transformations and node substitutions has been completed
  • Extending the Editor language has become more straightforward thanks to careful refactoring of its generator
  • The changes introduced to your project by migrations can be reviewed, corrected or reverted through Local History.
  • Languages and solutions can be easily cloned with a single mouse-click.
  • and a few more…

The What’s new page will give you full details of all the features in the MPS 2017.1 release.

We hope that you will enjoy using this new version of MPS at least as much as we have enjoyed creating it.
