# Rego

Rego language support in Zed is provided by the community-maintained Rego extension.

- Tree-sitter: FallenAngel97/tree-sitter-rego
- Language Server: StyraInc/regal

## Installation

The extension is largely based on the Regal language server which should be installed to make use of the extension. Read the getting started instructions for more information.

## Configuration

The extension's behavior is configured in the `.regal/config.yaml` file. The following is an example configuration which disables the `todo-comment` rule, customizes the `line-length` rule, and ignores test files for the `opa-fmt` rule:

    rules:
      style:
        todo-comment:
          # don't report on todo comments
          level: ignore
        line-length:
          # custom rule configuration
          max-line-length: 100
          # warn on too long lines, but don't fail
          level: warning
        opa-fmt:
          # not needed as error is the default, but
          # being explicit won't hurt
          level: error
          # files can be ignored for any individual rule
          # in this example, test files are ignored
          ignore:
            files:
              - "*_test.rego"
