Grammars / syntax highlighting

PRQL contains multiple grammar definitions to enable tools to highlight PRQL code. These are all intended to provide as good an experience as the grammar supports. Please raise any shortcomings in a GitHub issue.

The definitions are somewhat scattered around the codebase; this page serves as an index.


Since the Elm language coincidentally provides syntax highlighting suitable for PRQL, it may look better to mark PRQL code as Elm when the above definition files are not available.

For example, the following Markdown code block will be nicely highlighted on GitHub, Pandoc, and other Markdown renderers:

  1. ```elm
  2. from employees
  3. filter start_date > @2021-01-01
  4. ```

We hope that in the future these renderers will recognize PRQL code blocks and have syntax highlighting applied, and we are tracking these with several issues.
