Osmium is a syntax highlighter generator for ANTLRv4 grammars. It aims to support outputting TextMate highlighters (XML) and Pygments highlighters (Python).

You can run Osmium by simply running the following command:

java -jar osmium-<version>.jar [options]

If you need a list of all available options, run the tool with the -? option.

In order to build the tool, you can simply run the following command after cloning the repository:

./gradlew build --info --no-daemon

or the following if you are using cmd under Windows:

gradlew build --info --no-daemon

This will produce three different JAR files under build/libs in the project directory. The slim version can be used for development/embedding since it does not contain all the shadowed dependencies.
