antlr4-rddl

An ANTLR4 grammar for RDDL files.

Installation

The antlr4ng package is required for TypeScript code generation. It can be installed via

npm i

For the generation of Java code, the ANTLR4 grammar syntax support package is used. To adopt the folder structure as specified in this repository, you must add the following to your settings.json

  "antlr4.generation": {
    "outputDir": "../../generated/Java",
    "mode": "external",
    "listeners": true,
    "visitors": true
  }

Code Generation

Java code is automatically generated as soon as one of the .g4 files is saved.

For TypeScript code, either run

npm run build

or use the following command

antlr4ng -Dlanguage=TypeScript -o src/main/generated/TypeScript/ -visitor -listener -Xexact-output-dir src/main/grammar/antlr4/RDDLLexer.g4 src/main/grammar/antlr4/RDDLParser.g4
