Event Modeling Tools

The project combines multiple tools helping you with Event Modeling, such as Domain Specific Language (DSL).

Note

Previously the project's name was event-modeling-dsl.

Domain Specific Language

Domain Specific Language (DSL) for writing Event Modeling models. The DSL in textual format can be translated to various outputs, mainly to a diagram.

Event Modeling model file is usually defined in a text with prefered .evml file extension or as a Markdown code block marked with evml.

VS Code Extension

There is VS Code compatible extension published.

Note

There is a deprecated extension available under event-modeling-dsl identifier. Use the one with event-modeling-vscode-extension.

For VS Code use its official Marketplace. Hit Ctrl+P and type:

ext install LadislavGazo.event-modeling-vscode-extension

For VS Codium use Open VSX Registry.

Command Line Interface

The command line interface can generate SVG file out of .evml text definition.

Just call the CLI script like this:

./packages/cli/bin/cli.js svg ./packages/layout-headless/test/multiple-source-frames.evml
