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 extensions 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"
