Dependencies analyzer can be called from main menu or from popup menu on a set of modules/models::
The lower panel shows usages of items selected in the right panel in the left tree scope selection
With this tool it is possible to overview all the module (or set of modules) dependencies and used languages, detect cyclic dependencies as well as see in details paths that lead to the given dependency. The tool can be invoked from the project pane when one or more modules selected there.
Module Dependency Tool shows in the left panel all transitive dependencies of module and optionally all used (directly or indirectly) languages. It is possible to expand any dependency node and get all dependencies of the expanded node as children. These will be again transitive dependency but for the expanded node.
Select one of dependency nodes or set of nodes in the left panel. Right panel shows paths to the each selected module from its "parent" module. You can see brief explanation of each relation between modules in the right tree. It can be depends on, uses language, exports runtime, uses devkit, etc. For convinience the name of the target dependent module is shown in bold.
There are two types of dependency paths: Dependency and Used Language. When you select module in the Used Language folder in the left tree right tree shows only dependency paths making "used language" relation for the given module. To show "ordinary" dependencies on language as a module you should choose it out of Used Languages folder (like jetbrains.mps.lang.core in the picture below). It is possible to select several nodes (e.g. the same language dependency inside and outside Used Language folder), then you get union of paths.
If you want to track not only "visible" but also runtime dependencies you should check "runtime" option in toolbar. Only runtime dependencies are marked with "(runtime)" comment in the left tree.
By default dependency paths are shown in "from the shortest to longest" order. But there are still paths that are not shown: paths with the same tail part as one of the already shown path. It is still possible to see all such paths in the right tree with the "Show all paths" option. Only starting (distinct) part of path is shown, symbols "... -->" mean that there is continueation of the path already shown in the tree; you can follow path by double clicking its last element.
Modules participating in dependency cycles are shown in red color in the left tree. It is possible to see paths in cycle by selecting module dependency equal to parent or for convinience by using popup menu:
For some types of dependencies it is possible to show usages or safe delete with popup menu. For "depends on" (dependency without re-export) Dependencies Analyzer will be invoked on Show Usages.
UI for getting refactoring parameters now is removed from refactoring language. Now choosers for parameters are not called, it is not allowed to show UI in
ask boolean), keystroke has no effect. All this functionality should be moved to an action correspondent to the refactoring.
The following constructs added to the refactoring language:
is applicable refactoring<
isApplicablemethod, and there is no refactoring that overrides current refactoring for this target.
It is necessary to manually migrate user refactorings. Migration consists of
isApplicableclause to the action created; usually it is just
is applicable refactoring< >
executeclause to the action created; all the parameter preparations that were in
initof refactoring should be moved here; at the end it is necessary to execute refacoring with prepared parameters (with
execute refactoring< >
initof refactoring, they should be ready on entry to
init; you can still validate parameters and return false if validation fails
It is possible to suppress errors in editor (and in model checker) now.
If node is instance of a concept which implements ISuppressErrors interface, then all errors in this node and it's children won't be shown. It is also possible to define child roles, where errors should be suppressed, by overriding interface boolean method suppress(node<> child).
Also if node has attribute of concept implementing ISuppressErrors, errors in such node will be suppressed too.
There is default implementation of ISuppressErrors node attribute. It can be applied only to nodes that are instances of ICanSuppressErrors.
