Getting started

• Follow the instruction in CONTRIBUTING.md to install Penrose.
• Run roger trio packages/examples/src/set-theory-domain/tree-euler.trio.json from the repo root. The output SVG will appear in the console.

Using roger for local development

• If you are developing a module in core, you can run yarn start in the project root direcory, which will continuously watch your changes in core and update your build.
• Check the console before you run roger to make sure your changes in core are not causing any errors.
• If the build is successful, roger will now be using the most recent version of core when batch-processing Penrose programs.
