What is m+ plug-in?

m plus plug-in supports model driven development (MDD)*1 with the modeling tool Astah. This plug-in is free for both personal and commercial use.

Functions

Code generation

- Generates C++ / C# / Crystal / Golang / Java / JavaScript / Kotlin / Python / Ruby / Scala / Swift / TypeScript / Alloy / VDM++ code from UML model elements.
- Generates code from static structural elements (such as classes and relationships) in a model.
- Generates one file from one class basically. In Alloy, the plug-in generates one file from one package.
- Inserts User Code Area *2 into the generated code. The User Code Area is an area enclosed by "˅" and "˄". Handwritten code is allowed only in the User Code Area. The code in the User Code Area remains after re-generation.
- Supports programming language-specific extensions (e.g., enumerations in Python and decorators in TypeScript) using stereotypes and tagged values.
- Does not support round-trip engineering or executable UML method.

See the Usage and Tips sections.

Structural diagram creation

- Previews a structure of model elements using PlantUML*3 and Graphviz*4.

See the Usage section.

Directed graph creation

- Shows the reference relationship between model elements in a directed graph.

See the Usage section.

Diagram map creation

- Shows links between related model elements and diagrams across diagrams.

See the Usage section.

Relationship matrix creation

- Shows relationships between structural elements in a matrix format.

See the Usage section.

*1: Model driven development (MDD) is a set of software development approaches based on model driven architecture (MDA).*2: User Code Area is the same as what is called Protected Region or Protected Area.*3: m plus plug-in includes PlantUML under the MIT license.*4: If you are on Mac or Linux, you need to manually install Graphviz.
