Our release of MPS 2021.3 will be delayed until next year. That said, we can’t finish the year without giving you a glimpse of what you can look forward to. DOWNLOAD MPS 2021.3 EAP Experimental Kotlin language support An experimental Kotlin implementation is now bundled with MPS. While it supports most of the structure elements in the language (and their text generation), it still remains only partially supported. Stubs in common Kotlin code are also supported. On the JVM side, baseLanguage constructs (code and stubs) can be referenced in Kotlin through the jetbrains.mps.kotlin.javaRefs langua

Today we’re rolling out the last build in the Early Access Program for MPS 2021.1, and these are the last few features that will be included in the release. Try them out. Zoom in and Zoom out The font size can be quickly adjusted in the currently open editor window by holding Control/Command and rolling the mouse wheel. Font size is not persistent, so when you reopen the file, the text size will be reset to the default value. You can enable/disable the feature in settings in the Editor -> General section: Change font size with Ctrl/Cmd+Mouse Wheel. Improved performance on indent layout The

We are getting ready for the major release of MPS 2021.1, and the Early Access Program (EAP) is our way of sharing with you the new functionality that we have been working on in recent months. Here are the new features we’ve implemented in this version. Model viewer in diff dialog The MPS model viewer is enabled for merged commits in Git log. The viewer displays three panels – the center panel for the merged model and, the left and right panels for the models of the two merged branches. Revisions graph used for root annotation and root/node history The root annotation and root/node history al

The Early Access Program is an important part of our product development process for identifying critical issues with the new release features. If you encounter any problems, please report them to our issue tracker. Check out the new functionality that we have prepared for you. Improved access to $LOOP$ macro variables It is now possible to refer to the input node of a LOOP macro by using a LOOP.inputNode expression, removing the need to use a VAR macro. The index of the LOOP can also be accessed under the same namespace by using LOOP.index and replacing the previous user-defined context varia

Over the past few months we have been working to make MPS more usable, and we’ve been fixing issues reported by users. In this blog post, we describe this version's new functionality, and you can also watch our screencast with the main features. DOWNLOAD MPS 2021.1 New generator macro There's a new macro named $CALL-SITE$ that facilitates the insertion of a node attributed with a SWITCH/CALL macro into a designated place in the invoked template. Prior to the change, the template node with a SWITCH/CALL macro attached was generally ignored. Now if an invoked template/switch tries to use 'c

The Feature Freeze version contains the last features that will be included in MPS 2020.3. Let’s take a look at what we’ve prepared for you. DOWNLOAD MPS 2020.3 EAP Dynamic usages highlighting in the editor Dynamic highlighting, a long-awaited feature, has arrived. This feature is very similar to the existing Highlight Usages action (Ctrl/Cmd+Shift+F7). The difference is that dynamic highlighting works automatically as you type or navigate through the code. References to the node under the cursor are highlighted in the edited document almost immediately. You can still use the original Highli

We have begun our new Early Access Program for MPS 2020.3. Throughout this program we will focus on building stable new features for MPS 2020.3. 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 only and was not quite correct in the majority of cases. With the new approach, the annotation is constructed by comparing the models from different revisions. Error strip on project pane We are intr

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 of your test case as if you were testing an intention. You can choose to either run the quick-fix that is available on the selected node or you can choose a concrete quick-fix to run explicitly. Spe

Our Early Access Program for MPS 2020.2 has started, and the latest version brings a new set of features that we’re excited to introduce. DOWNLOAD MPS 2020.2 EAP   UI improvements to the VCS We’ve improved the windows in the Version Control System. The width of the editor area is no longer fixed, so the splitter now moves in both directions. The way changes are highlighted has also been improved. Additionally, we have replaced the triangles and trapezoids in the splitter area with smooth polygons. Tooltips for the changes are displayed both in the editor area and in the splitter a
