Ratio ESL

Ratio support for the Elephant Specification Language (ESL) in Python.

Quickstart

Installation

RaESL can be installed using pip install raesl[all] for any Python version >=3.11. For managed projects you can use:

• uv: uv add raesl[all]
• Poetry: poetry add raesl -E all

For RaESL's different subcommands and functionality, the wheel provides extras which you could provide instead of the all used above:

• doc: documentation generation using pandoc, Markdown and optionally LaTeX.
• jupyter: a Jupyter ESL kernel.
• pygments: an ESL syntax highlighter for pygments.
• rich: Rich doc output in the form of Plotly images.
• server: A language server to parse documents.

The default raesl compile command is always available.

Please refer to the usage documentation for more info on how to use RaESL.
