Let’s take a look at the new functionality we prepared. DOWNLOAD MPS 2020.3 EAP1 Improved root annotation in VCS The old root annotation algorithm used the results of the annotation obtained from the model text file. It worked for text-persisted models

The feature freeze is ready, which means that we will now be focussing on stabilizing the product so you can have a bugless (at least close to it) MPS 2020.2. Here are some of the features that you can expect for this major version. DOWNLOAD MPS 2020.2 EAP Test quick fixes in an editor test case The editor test language has been extended with the ApplyQuickFix concept. Use it in the code section

Here's a brief announcement of an upcoming feature that we would like to know your opinion on. One of the more visible changes that we’re preparing for 2020.1 is a set of enhancements to BaseLanguage that have been inspired by the Java language. You can look forward to: try with resources catch multiple exceptions string switch natively supported in the generated code local variable

Little progress can be made without honest feedback. The MPS online documentation was migrated to a new JetBrains platform earlier this year. Along the way, the MPS team has been putting effort into making the documentation more complete and up-to-date. To move forward with the documentation, we need your help: If you fail to find documentation for a certain feature. If you discover wrong

Deprecated code smells like rat. It is not a good sign to be using deprecated code in a projects for several versions. Here are a few tips that show how MPS can help you get rid of deprecated code. The handy migrations The Migration menu contains a Deprecated Code submenu with three migrations. The action Find Usages of Deprecated is undoubtedly the most useful one if you want to eliminate us

This is one recent feature that perhaps deserves some more popularization - jetbrains.mps.baselanguage.logging has been enhanced with two logging statements, which replace the now deprecated logging statements like error, warn, info and others: message outputs a logging message into the MPS Messages view and so provides a very convenient instant way to trace your code. If multiple projects are

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 langu

Here's another handy new little feature in 3.4 that we want to introduce to you - the Icon description language. This language helps describing and instantiating icons for various MPS elements: concepts, actions etc. Again, mbeddr has inspired us here, namely their iconchar language. The langage has two aims: 1. Allow for quick icon prototyping (e.g. making new icons for concepts) 2. Make ico
