Tests

Purpose

This project aims to build a Xtext definition of the PlantUML sequence diagram language with some minor extensions, like builtin support for typed http request/response message annotations.

Limitations

Currently, this grammar has the following limitations:

  • TEOZ PlantUML is not supported as of yet since it is still in alpha
  • Multiline ref/title/note syntax of the form 'ref ... end ref' is not supported, please use \n to create multiline content
  • Multiline skinparam using '{}' is not supported, please use multiple individual skinparam lines

Usage

Setup

$ git clone <repo>
$ cd <repo>
$ ./gradlew jettyRun

Then open to the generated puml web code editor by opening localhost:8080 in your browser.

Test

$ ./gradlew test

Debug Grammar

Firstly, you have to generate a debugable ANTLR Grammar file, by adding the debugGrammer = true flag to parserGenerator settings in GeneratePlantUML.mwe2:

component = XtextGenerator {
  configuration = { ... }
  language = StandardLanguage {
    ...

    parserGenerator = {
      debugGrammar = true
    }
  }
}

Afterwards, the task $ ./gradlew xyz.elite.xtext.languages.plantuml:generateXtext will also generate the file: xyz.elite.xtext.languages.plantuml/src/main/xtext-gen/xyz/elite/xtext/languages/plantuml/parser/antlr/internal/DebugInternalPlantUML.g. You may load this file and debug it like you would any other ANTLR Grammar, e.g. by using ANTLRWorks
