Haskell Lint GitHub Action

An action that runs hlint checks over Haskell code.

If there are errors found in the Haskell code then the action will fail.

It will insert inline suggestions into the PR:

Usage

Example Workflow

workflow "Code Checks" {
  on = "push"
  resolves = ["haskell-lint"]
}

action "haskell-lint" {
  uses = "domdere/haskell-lint-action@master"
  secrets = ["GITHUB_TOKEN"]
}

The GITHUB_TOKEN checkbox must be explicitly checked so that the action can create GitHub Check Runs.

Configuration

Configuration is done by setting environment variables

Name	Description	Required/Optional(Default)
HLINT_ACTION_LOG_LEVEL	Sets the log level for the action, or debugging purposes, one of [trace, debug, info, warn, error, fatal]	Optional(info)
ACTION_TIMEOUT	The timeout duration in integer seconds before the hlint check declares a timeout result for the GitHub Check	Optional(15)

TODOs

• Opens proper GitHub check runs
• Annotates lines in PR with suggestions
• Support hlint.yaml in repos
• Support hlint.yaml by reference (from S3/GitHub/etc...)
