New in JetBrains MPS 2023.2 232.8660.471 EAP (Aug 21, 2023)

New in JetBrains MPS 2022.3 Build 223.8836.1185 (May 2, 2023)

The constraint rules update (Client sponsored):
The Constraint Rules language was created to address Constraint language deficiencies. For this release, the Constraint Rules have taken a step forward in improving the usability of the language.
The constraint rules definitions can now be referred to from NodeTestCases. Previously, this was not possible.
The experimental constraint rules definitions allow logging messages to be specified in the Inspector window for better tracing and debugging.
The error message for constraint rules can be targeted for specific nodes’ properties or references. Instead of the error highlighting the whole node, it can be configured to highlight only a property or a reference.
Improved Module Class Loading:
MPS modules serve different purposes, ranging from a sandbox to play with your language to an active plugin code to alter MPS or IntelliJ IDEA platform behavior. To address this range of tasks, MPS relied on a few scattered and confusing flags and settings, like SolutionKind, IDEA Plugin Module Facet, Compile In MPS, and many more (see MPS-20726).
In MPS 2022.3, we’ve brought all these under a single umbrella. The Java Facet page for the Solution module was reworked to house all relevant settings and identify common scenarios to help language designers and users easily recognize a module’s intended use. IDEA Plugin Module Facet has been deprecated and will no longer be used. We’ve exposed the settings for Solution modules only – both Language and Generator modules take the same approach, but have their settings configured implicitly.
“Compilation” determines whether MPS will compile generated sources or if there’s another mechanism that compiles classes and MPS shouldn’t compile anything. Still, MPS assumes there are classes for the module in the case when “External Compiler” is selected. If your module is not expected to deliver classes for MPS use, like for a sandbox or a solution that the generated sources are part of another project, use “None”
The “Class loader” setting determines whether MPS is responsible for creating a class loader or if classes are loaded by code that contributes a module. One of the most common module contributors is IDEA Plugin. In this case, the “Module Contributor” setting tells MPS to use the IDEA Plugin class loader to access module classes
The last setting, “Contributes extensions to MPS”, determines whether MPS will try to load its plugins and extensions from the module. This is most common for pluginSolution and is implicit for Languages
Unless your module provides extensions, keeping the setting on “No” avoids unnecessary overhead from extension look-up. Classes are still available for any code that depends on a solution. Language runtime solutions or a solution with stub models are examples of modules that comes with classes but don’t provide MPS extensions
There’s also a migration that updates project module descriptors to reflect these settings in an explicit form for all module types, including Languages and Generators. We’ll keep old values (solutionKind and compileInMps attributes) in XML for a transition period until the next MPS release.
Migration sync with MPS extensions:
MPS has always had an active community that brings value to the ecosystem and we have always encouraged users to use external libraries to enrich the product’s functionality. Third-party libraries, such as MPS Extensions, have been key to improving the user experience for products built with MPS. Even though this has brought many benefits to the community, there is a significant downside – the user needs to wait for the migration of the third-party library to update the MPS version. We’ve been working together with itemis, our official partner and main MPS extension maintainer, to synchronize our releases for smoother migration to the newest version of the product.
Additional utility methods in the language definition:
Language designers can now reduce the amount of repetitive code by extracting it into helper methods right inside the definition root node. These additional methods can be defined in:
Constraints
Transformation and substitute actions
Inference and checking rules
Quick-fixes
Intentions
Intentions also allow for additional fields to preserve the values calculated in the isApplicable method to be used in the execute method.
Kotlin stubs for JVM:
It ‘s now possible to import stubs from compiled Kotlin/JVM libraries, while it was previously only possible to import Kotlin/Common libraries. With this improvement, it’s possible to use libraries compiled to JVM (Java, Kotlin, or mixed) through the Kotlin JVM model root in your module options.
For example, the Kotlin UI DSL has been loaded as stubs into jetbrains.mps.kotlin.ui.dsl module. While this library was already available as Java classes, this module allows you to reference it using Kotlin.
For a pure Java library, it doesn’t make any difference whether you use Java Classes or Kotlin JVM. The new functionality applies only to using Kotlin in the loaded library.
Kotlin edition improvements
Several minor changes and improvements have been bundled with this new version of MPS:
Kotlin classes are now rootable nodes and have their own icons.
Kotlin code can now refer to Java enum entries.
The this expression can now correctly refer to a label (e.g. this@SomeClass).
withKotlin flags in build scripts now ask for a $kotlinc_home macro instead of a previously hardcoded location.
Stubs have been improved:
Excluding / Including packages in the stub options now functions as it would with Java stubs.
Several methods with unstable IDs, leading to broken references, have been fixed.
Transformation to create a constructor from a type:
It’s now possible to create a constructor call for a given call using a right transformation by typing left parenthesis. This can work for any Kotlin type that supports this operation (this is extensible for user types) and can facilitate creating a default expression for a given type, like when creating a lambda from a functional interface type.
Improvements to extension functions in Scopes:
Extension functions were not always handled correctly in scopes, leading to some situations where it was not possible to select the right function.
These scopes have been changed to not exclude compatible methods in scopes. This comes at the cost of having some items in scopes that are not applicable due to the performance of the current type of system implementation.
The automatic resolution of function references can fix references in case a non-applicable function is selected.
Together with this new functionality, we’ve fixed a long list of bugs. Try the new version and give us feedback on our issue tracker. As for every release, don’t forget to review our Migration Guidelines before updating to the latest version.

New in JetBrains MPS 2022.2 Build 222.3345.1295 (Nov 1, 2022)

New in JetBrains MPS 2022.2 Build 222.3345.848 EAP 1 (Aug 23, 2022)

New in JetBrains MPS 2021.3.1 Build 213.7172.958 (May 3, 2022)

New in JetBrains MPS 2021.3 Build 213.6777.846 (Feb 15, 2022)

Experimental Kotlin language support:
An experimental Kotlin implementation is now bundled with MPS. Although it supports most of the structure elements in the language (and their text generation), it 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 language.
Hide revision action in annotate:
Some revisions may contain low-level migrations, and when they affect the whole root, it might be undesirable to see them in the ‘annotate’ column. The existing action Annotate previous revision opens the editor in a separate tab for a root at the selected commit. The new action Hide Revision allows you to exclude a revision from the annotation result in-place and show the result in both the editor and gutter. The excluded revisions can be restored with the opposite action Restore Hidden Revisions.
Information about hidden revisions is displayed in the notification panel at the top of the editor. It is also possible to restore hidden revisions by clicking on the corresponding link in the notification panel.
Optimization of Annotate revision action results:
The Annotate action in MPS is not as fast as the git blame operation for text files since the annotation result is constructed for the models. Annotate revision and Annotate previous revision actions use the same algorithm for constructing the result as the Annotate action and were slow as well. The result for the Annotate revision and Annotate previous revision actions can be constructed instantly using the result obtained from the initial Annotate actions.
Details dialog in merge roots:
The Show Details action has been introduced to give more details about the branches during merging. The action is accessible from the Merge revision window.
Short change descriptions in tooltips in Diff dialog:
We’ve introduced a new action that can change the description of the changes in the Diff dialog tooltips. The description is shorter and more readable.
Enhanced editor tooltips:
Now it’s possible to click on the links inside the tooltips, and the tooltips popup window stays inside the main application window. You can also scroll inside a tooltip if it has a lot of text.
New diff algorithm in the merge process:
A new algorithm for calculating changes between two models was introduced in v2020.3. The algorithm allows you to detect node movements and define new change types. Since node movement is often a result of wrapping the node with a new parent node, new change types were introduced for wrapping changes, as well.
The new algorithm was developed to find conflicting, non-conflicting, and symmetric changes for changes of new types. We’ve introduced a UI mechanism for switching between the algorithms with and without node movement tracking in the Merge window.
Nested wrapping and unwrapping changes detected in diff dialog:
Even though it was previously possible to detect internal insertions, deletions, and moves inside the wrapping or unwrapping change, nested wrapping changes were not detected. Now it is possible to detect nested wrapping and unwrapping changes.
Reorganized VCS settings:
VCS settings have been reorganized to make them more discoverable and usable. In Preferences / Settings | Version Control you will now find a list of the available settings to configure your VCS. Additionally, we’ve added a separate node for Directory mappings, and the background operations are now switched on by default.
Generation of compatible closures into Java lambdas:
MPS closures are now generated into Java lambda expressions if they are compatible. Incompatibilities include the usage of:
Yield operations
“Functional” abstract classes
Annotations
Local variables conflicting with parent scope
Mapping label for tuples:
We’ve introduced experimental functionality to use a pair of nodes as a key for the mapping, ‘node<>, node<> –> node<>’. This is useful in situations where you need to support two source concepts. If you would like to give it a try, it’s used the same way you use labels with one key node. You only need to add the second key by typing ‘,’ to get the second field.
Access all values of two key mappings in generators:
Besides the Mapping label for tuples feature, we now support a query to access all known mappings for given two keys, genContext.get output list LABEL for (node1, node2).
Performance trace reports time spent resolving dynamic references:
Because of numerous scope evaluations, resolving dynamic references often slows down model-to-model transformation. Performance trace hides this vital piece of information under a vague “restoring references” title. Now, the time spent restoring dynamic references is reported separately from time spent restoring regular or static references.
Project migration improvements:
In previous versions of MPS, for project migrations you had to create an ApplicationComponent class and register it in the plugin.xml. This was quite tricky, as you had to modify the folder structure of the plugin folder and copy over some files manually.
We have simplified the process of creating project migrations in this release. You only need to create a plugin solution, write the migration and application plugin root, and include this plugin solution with the build script.
Ant <migrate> task improvements:
The Ant <migrate> task now supports multiple project specifications and can migrate several projects at once. You can either use nested <project path=””/> elements or regular Ant’s <dirset> to enumerate project locations for the task.
Method references:
You can now use method references for baseLanguage methods with the jetbrains.mps.baseLanguage.methodReferences language. Like closures, they can be used as substitute for functional interfaces, function types, and functional abstract classes.
Closure untyped parameters:
Closure parameters’ types can now be specified as “var”, which means the type can be inferred automatically. Partial support for this already existed with SmartClosureParameterDeclaration (for collection language and simple function calls), but the new notation can be used in any context where closures are supported.
Checkout and Rebase onto Current for remote branches:
The action to Checkout and Rebase onto Current lets you check out the selected branch and rebase it on top of a branch that is currently checked out. This was possible only for local branches before, but in MPS 2021.3 you can use it with remote branches as well.
New Changes tool window:
In MPS 2021.3, the IDE shows the difference between commits in a separate Changes tool window located on the left of the editor.
New Push All up to Here action:
This feature allows you to push only the commits you are confident about and leave the rest for later. To use it, pick the commit you want to stop at, right-click on it to call the context menu, and select the new Push All up to Here action.

New in JetBrains MPS 2021.1 Build 211.6556.759 EAP 3 (Mar 29, 2021)

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 algorithms were based on the ordered list of file revisions, calculating the changes for the root between two adjacent revisions. It was possible, however, for these revisions to be from two different branches, in which case the obtained changes made no sense. Merge revisions also were not handled correctly. The changes from the older rounds of revision could be erroneously displayed as changes from the newer merge revision. Now the algorithm considers the revisions graph when it calculates the change history.
Method signature refactoring improvements:
The Method Signature refactoring dialog now includes a way to specify default values for new arguments or arguments whose types have changed. When a parameter is removed but is still used in the method, a new local variable is introduced so the reference is not lost. In addition, vararg type parameters are now handled.
When the call of a method does not match its signature, an intention action allows you to change the method signature according to the call. This intention action has been improved. It now maps the existing parameters more intelligently, so the maximum number of existing parameters are reused and their references are kept.
New options in BaseLanguage comments:
The lang.text language has been enhanced with several new capabilities, which directly enhances single and multi-line comments in BaseLanguage:
Text selection now allows you to select only parts of lines when selecting up and down.
Actions such as bold, italicize, and underline work on selection.
Copy/paste from and into plain text has been implemented.
Bullet and numbered lists are now supported.
Improved expressions in lang.smodel:
The expressions model.roots(), model.rootsIncludingImported() and model.nodesIncludingImported() now support #expression for specifying concepts, just as model.nodes() does.
Compiled generators:
Generator Preferences in the IDE contains an option called “Warn when child cannot be placed into role”, which checks whether the nodes template that is produced fits into the proper role of a parent node. The option is available through build project settings as well. The generator may issue a warning, which usually indicates there’s some inconsistency in the templates, such as an improperly placed Template Fragment or COPY-SRC annotation.
Compiled templates, however, didn’t perform the check. With MPS 2021.1, compiled templates now go the extra mile and check whether children are properly placed into parent nodes if the option is active.
Apple Silicon Support:
You can now use MPS on Macs that have an M1 chip. To get started, download the installer for JetBrains MPS for Apple Silicon directly from our website or get it from the Toolbox App.
Space is here:
The Space plugin is now bundled with MPS 2021.1.
Auto-import settings:
With MPS 2021.1, the Import Settings dialog that appears every time you install a new version of MPS will only be shown when the user doesn’t have the appropriate settings and configurations.

New in JetBrains MPS 2020.3.3 Build 203.7717.1351 (Mar 24, 2021)

New in JetBrains MPS 2021.1 Build 211.4961.341 EAP 1 (Feb 16, 2021)

New in JetBrains MPS 2020.3 Build 203.5891.1014 (Jan 11, 2021)

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 ‘call site node’, the node is processed as a regular template and the outcome is supplied to the invoked template/switch as an implicit argument that can be inserted into the desired location.
There’s also now an invocation of the reduce_Expressions switch, parameterized with a template node (trace method call) with a property macro and reference macro (that makes the method call point to a proper method declaration elsewhere)
Template and Switch declarations have a flag, which is toggled by intention, that indicates that it would like to use the call site node. It’s an error to use the $CALL-SITE$ macro inside a template/switch that didn’t flag the need to get $CALL-SITE$. There’s no need to specify an explicit argument in CALL/SWITCH – the MPS generator can tell if the template/switch being invoked needs a call site and further evaluates the template, including the macros, of CALL/SWITCH prior to processing it.
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 Highlight Usages action to "pin" usages of the currently selected node while you navigate away from it. When you do, dynamic highlighting will continue to highlight the node under the cursor.
This feature can be turned on or off in the MPS Editor settings with the Highlight selected node checkbox.
Improved switch statement in BaseLanguage:
In addition to some editor improvements, the switch concept now supports using multiple cases for the same statement.
Error strip on project pane:
We are introducing a new way to display errors, warnings, and messages in the Project pane. The Error strip helps to organize the messages on the Project pane. You can deactivate it via the Logical View setting button.
Changes to how module facets are handled:
MPS no longer forces you to use any specific module facet with a given module. Facets associated with a module are recorded inside the module descriptor file, which is now the ultimate source of information. We had already made the Tests facet completely optional in previous releases, and now the last one, Java, will no longer be enforced. Please note however, that unchecking the Java module facet in the Language module properties will exclude the language from the class loading mechanism and render a completely different experience. We’ve implemented this change to facilitate unobtrusive support for target languages other than Java.
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 in the majority of cases it was not always correct. With the new approach, the annotation is constructed by comparing the models from different revisions.
Tracking moved nodes in the Diff dialog window:
The previous algorithm for calculating changes between the two models could not detect certain types of changes. Node movement was detected as two independent changes: insertion and deletion. It is now possible to show the node movement as one movement. Furthermore, it is also possible to detect internal changes inside the moving piece
New welcome screen:
We’ve updated the look and feel of the Welcome screen. It now includes not only project selection but also a variety of dialogs to help you customize your IDE to your needs. First and foremost, the Projects page has more space, making room for extra projects. It is also easier to search for the desired project from the search field. The Customization page takes you through the primary interface settings, like the color theme, IDE font, import actions, and sharing preferences.
Other improvements
VCS menu reordering:
The VCS menu has been renamed to match the version control system that you are currently using.
Commit and Push button:
Now the two most popular buttons – Commit and Commit and Push… – are explicitly shown on the Commit screen. You can push the changes to the remote repository immediately after the commit, you no longer have to scroll through a drop-down list to reach the Commit and Push button.
Improved branches:
This release comes with several enhancements for branches. The IDE now automatically corrects unaccepted symbols in the names of new branches and you can now see all the actions related to the current branch.
Splitting the editor with drag and drop tabs
Having several tabs open is always convenient while working on a big project. With MPS 2020.3, you are able to split the main editor screen either horizontally or vertically by dragging and dropping a tab to the desired position. When you are dragging a tab, the editor will highlight possible locations to drop it. The IDE displays pinned tabs at the beginning of the tab bar.
We fixed and investigated a long list of bugs. Let us know what you think in the comment section and report any problems to our Issue Tracker. Download MPS 2020.3 and give it a try, or install it using the Toolbox App.

New in JetBrains MPS 2020.2 Build 202.6397.948 (Sep 14, 2020)

UI improvements to the VCS:
We’ve improved the look and feel of the Version Control System. The width of the editor area is no longer fixed, so the splitter can now be moved in both directions. The way changes are highlighted has also been improved. Tooltips for the changes are displayed both in the editor area and in the splitter area. Additionally, we have replaced the triangles and trapezoids in the splitter area with smooth polygons.
Improved root and node histories in VCS:
The existing "Show Root History" action in VCS did not always display results that were correct. With this fix, the models are compared instead of the source files, which results in the output always being meaningful. Furthermore, it is now possible to display the history for any node, not just root nodes.
New change type in VCS:
MPS is now able to structurally diff/merge non-referenceable parts of BaseLanguage models. For any instances of BaseLanguage concepts that are not supposed to be reference targets (e.g. BlockStatement or ForStatement), the MPS diff/merge algorithm will ignore the ID of the node and compare the actual node structure instead. This will prevent MPS users from struggling with structurally identical changes leading to merging errors.
Therefore, we’ve added a special way for these non-functional ID changes to be handled in VCS. Changes to the new type can be hidden in the Diff dialog with the help of the new toolbar button. Additionally, during the merge process, changes in two branches are considered to be non-conflicting if they differ only with respect to the IDs of nodes which cannot be a target for the reference.
We are going to improve the algorithm even more in upcoming MPS releases.
Select next sibling:
It is now possible to use Shift + Left/Right to select multiple sibling nodes. This shortcut can be used for method parameters, array literal values, or statement siblings.
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 either to run the quick-fix that is available on the selected node or you can choose a concrete quick-fix to run explicitly.
Specific Fix:
The fix that is available on the selected node:
Color scheme switcher and font settings
You now have the option to switch the editor’s color scheme without changing the IDE theme. The new settings can be found in Settings -> Editor -> Color Scheme.
Font settings have been moved from Settings -> Editor -> General to Settings -> Editor -> Font (as they have in all other JetBrains IDEs). And under Settings -> Editor -> Color Scheme there are two additional sub-settings: Color Scheme Font and Console Font, which can be used to configure the font in the editor and the terminal (the MPS console is considered an editor for now). And yes, ligatures have finally come to the MPS editor!
You may notice that some checkboxes are missing from Settings -> Editor -> General. They‘ve actually just been moved :
Antialiasing can be configured in Settings -> Appearance & Behavior -> Appearance in the Antialiasing section, and they can be configured separately for the IDE and for the Editor
Power Save Mode has already been added in Main Menu -> File -> Power Save Mode – the redundant duplication was removed from the settings
And one last thing – switching the theme or the color scheme of the IDE no longer requires restarting the IDE for the changes to take effect!
Enhancements to Generation Plans:
The ‘Show Generation Plan’ action offers a handy resource for understanding the exact steps involved in the transformation of a model. Now, in addition to transformation steps, the action also identifies where the generation plan comes from (e.g. from a custom module facet or a devkit), and gives its name along with a link to the generation plan node.
Moreover, the transformation steps keep the name of the generator module when the name of the template model is not qualified, which helps keep similarly named models distinct.
One common complaint has been that it is difficult to find languages excluded from a model transformation due to the restrictions of a generation plan. We are happy to report that we’ve addressed this issue. Languages that are used in the model but that are not covered by the associated plan are now included in the result of the ‘Show Generation Plan’ action. In addition, the ‘Used Languages’ tab in the Model Properties section also offers a warning about such languages.
Improvements to the Build language:
There’s now an option to use macros for version parts in idea branding (BuildMps_Branding). The ${version.major}, ${version.minor}, ${version.bugfixNr} and ${version.eap} macros have been added to the MPS build script. The old version format still works, but it is deprecated. To switch to the new version in your build script, use the "Convert deprecated branding version to the new format" intention.
Other improvements:
Full GitHub pull request support:
The details of open pull requests are now one click away in a separate vertical tool window. The main editor window shows the conversation, and you can add comments directly. Pre-commit check results are displayed at the bottom of the window. If you have permission to manage pull requests, you can now browse, assign, manage, and merge them, view and submit comments, and accept changes right from inside the IDE.
Improved Git Actions dialogs:
For this release, we’ve revised the visual consistency for merge, pull, and rebase dialogs. We’ve also improved the dialogs so that they clearly identify what Git commands will be executed, and we’ve included some missing options. We’ve also added –rebase and –no-verify to the pull and merge dialogs, respectively.
Squash and drop local commits from the log:
You can now select multiple commits from a local branch and squash them. In the Git tool window, open the Log tab, select local commits, and choose Squash Commits. If you decide to change the commit message, all the changes in those commits will be put into one single commit together with the updated message. In addition, you can now drop commits from the Git log.
Improved result display for the Compare Branches action:
When you compare two branches in MPS 2020.2, the IDE shows their commits all in one view by opening their logs in the editor. In contrast to the VCS tool window, this view has enough space for a full report on what commits are in each branch and which files are affected.
Authorization:
We’ve switched GitHub authorization from the password-based system, which is deprecated and will stop working soon, to OAuth.

New in JetBrains MPS 2019.3 Build 193.1166 (Dec 23, 2019)

Model unloading:
In previous versions, MPS wasn’t able to unload models. This meant that if you had been working with MPS for a long time and had accessed many models, all these models would be loaded into memory. So, memory consumption would grow over time, which also affected garbage collector pauses.
Now it’s possible to remove all models from memory explicitly by clicking the memory indicator or by setting a scheduled cleanup in preferences. This feature is currently experimental, and we’ll continue to improve it in future releases.
Concept and Interface conversion:
We’ve added a new intention that converts a concept to an interface concept and vice versa. This can be used when creating a language structure, and it does not change usages.
Quick Definition Action:
Quick Definition is similar to its counterpart in IntelliJ IDEA. Click on a node, press and hold Ctrl-Shift-I, and you will get a popup with the definition of the node. In this popup, you can navigate, select other nodes, and perform the Find action. This way, you don’t need to open a new tab every time you want to have a quick glance at the node.
Quick Definition works in completion menus as well. If you don’t know what the node refers to, you can press Ctrl-Shift-I and see its definition alongside the completion menu. As you navigate through the completion menu, the contents of the popup will change accordingly.
Standalone generator modules and multiple generators per language:
Now you can create more than one generator for a language, and either host them inside a language (as in previous versions) or add them next to a language as a regular top-level module. Using generator plans allows you to take full advantage of multiple generators. To help with the transition, only one of the language generators will continue to be involved for a model without an explicit generation plan. The new generator can be created from the language context menu, and the following dialog has a new checkbox you can use to make it standalone.
Create from usage:
Now it’s possible to create concepts, methods, and classes from usages in code. The intention can create a class on new statements, methods in expressions, as well as concepts and interfaces in child/reference roles and in extends/implements.
Generating valid java identifiers from INamedConcepts:
A new generator statement allows you to generate a valid Java identifier from any INamedConcept. This will create a unique name by removing illegal symbols, capitalizing, and adding a prefix if needed.
Find Usages: new statement to report arbitrary search results when writing a finder:
In previous MPS versions, the add result statement on the finder only allowed for node<>-based search results. Now with add raw result, the language designer can display any result that the Find Usages view is capable of visualizing.
New Plugins from the IntelliJ Platform:
Settings repository – Lets you share your settings between different instances of your IDE.
Task Management – Allows you to manage your tasks from an issue tracker.
Change Reminder – Predicts files that you may have forgotten to modify based on your commit history.
What’s been fixed:
Generator: control the dynamic reference warning:
For a long time, the MPS generator has had the ‘Resort to static reference’ setting, which helps to address performance issues. The MPS generator issues a warning when it tries to resolve a dynamic reference but fails, and this causes a lot of warnings given the fact that not all generators adhere to a strict reference construction approach using label mappings (i.e. they instead stick to plain strings for identifying the reference target). Therefore, we’ve added a new setting to control whether the warning appears. (“Warn static reference could not replace dynamic”, is off by default). This issue was among those that received the most votes in the Generator subsystem.
JavaStubs loading performance improved:
We have significantly improved performance when loading stub models, especially from large sets of jars and jars with highly dependent packages. Loading times are now 2 to 3 times faster on our target project (from 18 seconds down to 6 seconds), and this boost has also been backported to versions 2019.1 and 2019.2
Build language: explicit model roots:
MPS used to treat only a specific set of files as models, namely *.mps and *.mpsr. However, with custom model persistence, the file names differ. To make sure that all the necessary model files get bundled when a module is built, there’s an explicit model root declaration for a module in the build script that facilitates custom file name patterns.
Documentation:
The custom-persistence samples and documentation for the new build solution wizard have been updated. The generation-time errors in the Math sample and the broken links on the documentation pages have been fixed. Several dialogs and tool windows have also been corrected.
Base Language:
Binary and octal literals are now supported, and type parameters in Javadocs are handled correctly. Many other issues have been fixed as well.
Quick-fix to update module/model identity objects:
There are concepts in the SModel Language that identify models/module and bridge the node to Java. These concepts preserve the names of target objects and names that could become obsolete when a target is renamed. MPS detects outdated names and provides a quick-fix to bring them up to date for objects from SModel Language.
Module Facet update:
For a long time, ‘Java’ and ‘Tests’ module facets were unavoidable attributes of a module. Using filesystem locations requires hard-coding them in implementation. We are moving toward giving language designers greater control over various aspects of modules. Therefore, we’ve made a change in MPS to store these facets and their settings explicitly. With the ‘Tests’ module facet, language designers now have complete freedom, and MPS no longer demands that the facet be present for the Language module. To ensure a smooth transition, we still force the Language module to keep the ‘Java’ facet at all times. We are going to lift this restriction in the next release. The change also helps with module deployment by controlling the deployment platform of a module.
Surround with:
The Surround with… action is now available when multiple nodes are selected. Previously it was enabled only for selections containing a single node.
Show Affected Files action in Root History dialog:
For a revision in the root history, you can now look at the other files that were changed in the same revision.
Root History for models in per-root persistence:
When it was introduced in 2019.2, the Show Root History action, was only available for roots from models kept in a single file. Now, models in per-root persistence are supported as well.
Update of the Favorites view:
The old Favorites view was fairly outdated and full of issues. We decided to get rid of it completely and integrate the stable and well-maintained IntelliJ Platform Favorites view in its place. At the moment, we support modules, models, nodes, and properties as entries that can be added to favorites. We are planning to extend this integration to allow more functionality over the elements from the Favorites view, to improve the control users have over projects and provide them with more ways to access frequently used project elements.
Meta-languages styling:
All meta-languages now offer the same style and editing experience with respect to, among other things, keyboard navigation, placeholder cell behavior in editors, and “New Root” appearance.

Merge Driver:
We advise installing this bug fix and update the merge driver. You can update the merge driver by clicking on the VCS add ons notification. Then choose the “Get merge driver and settings” from the dialog. This does 2 things: it updates/creates project settings to point for actual merge driver and updates merge driver itself.
Migration Scripts:
This version comes with some fixes for the migration scripts. If you encounter problems in the migrated code from MPS 2019.2, you can revert the problematic changes and invoke ‘Execute Re-Runnable Migrations’.

Custom style and priority of completion items
Language designers can set the style and priority for the items in the completion menu. It’s possible to change the background and text color, bold and italic formatting, and it’s even possible to hide items. Note this feature is experimental and its design may undergo changes in the future. Learn more about it.
Generator Language:
Support for automatic type inference introduced for new VAR macro:
VAR macro now supports multiple variable declarations per macro in the Generator language. The type is deduced from the declaration query unless it is overridden.
Plugins support
Client Sponsored:
Use MPS plugins from the migration ant task:
Now, if a plugin is needed for a project to migrate, this can be specified in the <migrate> ant task. The corresponding plugin will be enabled, together with its dependencies. We’ve also integrated this feature into 2018.3.5 following a client support request.
Client Sponsored:
Plugin deploy support in the "run code from solution" build script instruction
The "run code from solution" instruction allows you to enable plugins in the MPS instance that will run the code. The dependencies of the plugin will be included. This feature was also integrated into 2018.3.5 following a client support request.
IDE Improvements
Create a custom UI theme:
Add a touch of color to your day! The IntelliJ Platform has just introduced this cool feature, and since MPS is based on it, now you can customize the UI themes for your IDE too.
Import the new predefined themes as plugins or create your own from scratch with IntelliJ IDEA. Try our new Cyan Light Theme and Dark Purple theme.
JUnit run configuration now accepts plugins to deploy:
Similar to an MPS Instance run configuration, now you are able to provide a list of IntelliJ IDEA plugins to be deployed on test execution. The ‘before launch’ task, ‘Assemble Plugins’, is available in JUnit run configuration as well. It automatically builds the plugins being deployed and copies the artifacts to the settings directory.
Client Sponsored:
Sorting in the ProjectPane:
We've added TreeNodeSortService to manage ChildComparatorProvider contributions which gives you full control over the MPSTreeNode children in the ProjectPane tree. Users will now register/unregister providers from their plugin’s application or project parts.
Indication of incoming and outgoing commits:
The IDE now indicates if the incoming and outgoing commits are available for individual branches in the Branches popup. Simply enable the new ‘Mark Branches that have incoming/outgoing commits in the Branches popup’ option in Preferences/Settings | Version Control | Git.
BaseLanguage:
Static Methods in baseLanguage Interfaces:
MPS now allows you to create static methods in interfaces. Remember to import baseLanguage to use this feature.
Miscellaneous:
Goodbye Confluence, hello Help Center:
Since forever, Confluence has been the home of the MPS documentation. Now it’s time to grow up and move out to our own place. We are migrating all the documentation to our Help Center; the User guide and Fast Track Tutorial are already accessible there. Expect more documentation improvements in future releases.
Stub methods signature:
The return type of the method was removed from the MPS node IDs created in Java stub models. From now on, the true method signature defined by the Java language specification is used to identify methods. You don’t have to resave all models, referencing a method from sub model, if the return type was changed in a new version of the library. Automatic migration will resave all MPS models and correct all existing references to stub model methods.
New meaning for the 'Compile in MPS' checkbox:
If the 'Compile in MPS' checkbox in module properties is not selected, this no longer implies there's a connected IntelliJ IDEA instance to perform code compilation. The checkbox can be understood as "either compile in MPS or do not compile at all".
MPS shows aggregated languages automatically:
Structure aspects now manifest the languages they incorporate by aggregation (i.e. using a foreign concept in a child role). It’s no longer necessary to import such languages explicitly into a model that uses an aggregated language will be automatically used while editing.

SModel language enhancements:
In some cases, you have to deal with raw pointers (like SNodeReference or SModelReference). Working with them can be puzzling since it's hard to create and operate them. To make working with pointers easier we bring new types and operations in SModel language.
Node pointer:
We have made working with node pointers easier, by introducing a new "node-ptr<>" type. These pointers can be resolved to the actual nodes via the "resolve" operation. The "node-ptr/ ... /" expression is a replacement for the old "nodePointer/ ... /" construct, which is already deprecated. Migration scripts are created to take care of the conversion of the expressions.
Setting references with pointers:
When setting a target to a reference link, there is no need to access the target node. A pointer to the target is enough. The "set ptr" operation applicable to reference link access expressions sets the reference target to the specified pointers. To check that a node is the one specified by a node pointer, the new "is" operation should be used.
Strict typing rules for smodel types:
The typing rules for SModel types have been made stricter. The SNodeReference interface methods are no longer available on “node-ptr" values. The downcast operator should be used to explicitly obtain SNodeReference. Additionally, the "pointer" operation on node instances now returns "node-ptr" instead of the regular SNodeReference.
Node-ptr expressions in reference macro:
The reference macro was modified to accept node-ptr expressions. We verify the pointer type returned from the reference macro in accordance with the type of the reference.
Node Id to specify pointer:
Now you can use the model name and node ID to specify a pointer to a non-named concept instance or for hard coding a reference as a string.
Model pointers:
The "model-reference" type has been refactored into "model-ptr<>". This pointer can be resolved to the actual model via the "resolve" operation.
New Migration scripts:
We have introduced a couple of migration scripts that may help you migrate old SModel Language constructs like the node/.../` expressions, undesirable quotations or downcasts. To run them, go to Tools -> Scripts -> Enhancements... and choose "SModel Language Enhancements (node-ptr<> and model-ptr)". Also, in the same window, there is the "Use node pointers in reference macro queries" option available that handles old constructions in the generator macros.
Improved scoping for SModel queries:
Smodel queries now behave more intuitively towards the scope they operate on. If a scope is declared as a parameter to a specific query, the query is executed on the whole scope including any read-only models, not only from editable models, like it was before.
Editor:
Show reflective editor for the subtree:
Now you can show the reflective editor for a whole subtree. To do so, select the node and press Cmd/Ctrl+Shift+[ or choose “Show reflective editor for subtree” from the context menu. For going back to the regular editor, press Cmd/Ctrl+], Cmd/Ctrl+Shift+] or right-click the option “Show regular editor for the Subtree”. Showing the reflective editor for just the current node is still available by pressing Cmd/Ctrl+[ or from the context menu.
Transformation menu for property and reference cells:
The transformation menu language has been consistently enhanced to support property and reference cells. Property and reference transformation menu parts allow you to customize the menus for property and reference cells better than the “inline menus” used previously.
The two key advantages are:
They can be attached to any cell; not just property and reference cells.
They can be applied to the completion as well as to the other locations – context assistant, context menu, and side-transformations.

Defining Completion actions in Transformation Menu and New Substitute Menu Language:
New location named "completion" was added to the transformation menu language, so you can define regular transformation action for the completion menu.
New Substitute Menus language has been introduced. Substitute Menus are now defined in the editor aspect and could be referenced from the transformation menu.
Generator - attribute handling
Generator used to copy node's attributes "as-is" during transformation of a node. With growing adoption of attributes and attributes getting more complicated it became apparent we need to treat attributes more carefully. Now, generator tries to update references of an attribute the same way it treats references of any other copied node (i.e. if a reference points to an object inside transformed model, Generator redirects it to corresponding node of an output model). Besides, child nodes of an attribute are subject to regular transformation sequence, i.e. they are checked against Reduction Rules and transformed accordingly. Note, however, use of complicated attributes (with references and children) is not endorsed. It's very easy to over- and misuse attributes, think twice before you put too much logic there.
Cross-model generation - debug information about mapping labels in checkpoint models:
To ease debug of cross-model generation scenarios, it's handy to know mapping labels actually exposed at a given checkpoint. You may have noticed a dedicated root inside each checkpoint model that lists mapping label names along with pointers to input and output nodes. Thus, next time your cross-model reference doesn't resolve, inspect corresponding checkpoint model to see if there's indeed a label for your input.
Find usage for solutions and devkits:
It was possible to find usages of a language right from the Project Pane with Alt-F7 for quite some time. Solutions and devkits, however, lack a mechanism to discover their uses. With DevKits that associate generation plans and solutions that holds these plans, we were surprised to find out one can't easily discover e.g. all models that would be generated with a given plan, and rushed to add 'Find usages' action to these modules as well.
Generating simple icons:
There was always a way of specifying an icon for concept. Previously, one should have created a .png file to add an icon for a concept. Now, there's a possibility to describe simple icons with text and get them drawn at generation time (i.e. to "generate" icons). The icons should start being displayed right after generation.
It's also possible to use icons, either described with text or loaded from a png file, in any UI component, action etc. There's an "icon{}" expression in resources language for that. It converts an abstract "icon description" to javax.swing.Icon

New in JetBrains MPS 3.1 Build 135.944 (Jun 30, 2014)

Support for diagram editor:
Diagrams can be used within the context of projectional editor
Basic diagram editing support: add, remove, copy, paste diagram elements
Code completion aid for new elements creation
Linking diagram elements with drag and drop
Type checking error highlighting
Customizable shapes and support for custom shape libraries
Automatic orthogonal edge routing
Diagram palette for quick elements creation (experimental)
Generator performance and usability improvements:
In-place transformations:
With in-place transformations, generator avoids copying large models between generation phases and instead applies changes directly to the original model. This makes generation faster and more memory-efficient.
Note: in-place transformations is not compatible with any code that makes an assumption that an output model exists on every generation step. You can opt-out of in-place transformations in generator preferences.
New generation trace:
Generation trace was updated to only contain information about the steps where actual modifications were made for each node. This results in the huge memory saving during generation, and also produces much more usable results for the "Generation trace/Generation traceback" viewer.
Parameters in template switch:
template switch now supports parameters similar to the template declarations. Use the new $SWITCH$ macro to pass parameters to the template switch, same way you do with $CALL$ macro. The old $SWITCH$ macro was deprecated, and can be migrated to the new one by the intention or the migration script.
Generator options in build language:
You can now specify generator options from within the MPS build script.
Editor improvements:
Text-like expressions editing:
MPS automatically applies side transforms for parentheses in BaseLanguage, making expressions editing very much "text-like" experience, despite projectional nature of the MPS editor.
Better formatting within comments:
Thanks to improved style inheritance mechanics, MPS now properly colors and stylise keywords, and other BaseLanguage elements placed within the comments.
Automatic reference re-resolving:
MPS editor now tries to automatically re-resolve broken and out-of-scope references in the background. This eliminates the need to update each broken reference manually one by one (with Ctrl-Space) after the valid reference target becomes available in the scope.
Styles improvements:
Style priorities and selective property inheritance
Support for custom style attributes
Testing framework improvements:
Navigation to code:
Clicking on a failed test in the error report window will now navigate directly to the failed check attribute in this test, so you can easily identify the cause of the test failure.
Constraints checking in tests editor:
Tests editor now validates scope visibility rules, as well as other structural constraints.

New in JetBrains MPS 3.0 Build 129.350 (Sep 23, 2013)

With MPS 3.0 plugin you can extend your existing Java applications with the power of MPS DSLs, without leaving IntelliJ IDEA.
Using MPS DSLs from Java:
With the version 3.0, MPS provides seamless integration between MPS BaseLanguage and Java within IntelliJ IDEA. As with Kotlin and Groovy, you can reference BaseLanguage classes and libraries from the native Java code and back, and use the full power of IntelliJ IDEA refactorings and navigation.
Switching from Java to MPS BaseLanguage:
MPS 3.0 allows you to convert selected Java classes to BaseLanguage classes. Your Java code will be parsed, transformed into BaseLanguage and saved to MPS model. All references will be re-resolved automatically. From this moment you’ll be able to use DSL extensions within the converted classes.
No need to create separate MPS models:
You can now create MPS BaseLanguage classes, interfaces, and any other root nodes directly under Java packages, - no more need to wrap them within a separate MPS model. This cleans up project structure, and simplifies version control and merging.
Adding MPS modules as libraries in IntelliJ IDEA:
You can now add dependencies from any project module in IntelliJ IDEA to the packaged MPS modules using MPS Modules Library.
MPS generator uses IntelliJ IDEA out-of-process make:
MPS DSL generator performance was improved by switching to IntelliJ IDEA out-of-process make.
Editor:
Multiple editors, default editor, and more
Overriding editor components:
Editors are frequently composed of reusable editor components. Extending languages can now override some of these components defined in the extended language, while reusing the other components and preserving the overall editor layout.
From version 3.0, MPS allows language designers to define more than one editor for the concepts within their DSLs. The user of that DSLs will then be able to choose the editor which suits their needs the best, via popup menu. It's even possible to have several editors open at the same time. The contents of these editors will be updated synchronously.
New way of handling editor selection:
It's now possible to customise the behaviour of cursor positioning in editor.
It can be done in two steps:
(Optionally) tag any editor cell with the Custom ID;
Use node.select operation in action handler to precisely position the cursor.
Default editor:
If no editor is defined for a concept, MPS is now using a so-called default editor, which allows to view and edit node hierarchy as a tree structure. This editor is also used as a fall-back solution in case of any problems with the user-defined editors.
Open API:
MPS 3.0 introduces the Open API, which provides read-only access to the whole project and models structure. This API is now used everywhere across MPS, and is also intended to be used by any MPS extension.
Custom persistence API:
MPS models are now well separated from the underlying data storage, allowing for custom formats. These can be provided through Open API and alter the way models get persisted. Two types of persistent formats come bundled with MPS:
the traditional XML format;
a new, more efficient binary format.
