Checks-Out

Checks-Out is a simple pull request approval system using GitHub protected branches and maintainers files. Pull requests are locked and cannot be merged until the minimum number of approvals are received. Project maintainers can indicate their approval by commenting on the pull request and including "I approve" in their approval text. Checks-Out also provides integration with GitHub Reviews. An accepted GitHub Review is counted as an approval. GitHub Review that requests additional changes blocks the pull request from merging.

Development

Checks-Out is a fork of LGTM. Our git repository contains the commit history from the upstream project. We are actively seeking contributions from the community. If you'd like to contribute we recommend taking a look at the issues page. You can pick up an open issue and work on it, submit a bug, or submit a new feature request for feedback.

Features

Checks-Out has several features that distinguish itself from the parent LGTM project.

The most popular feature is the ability to specify multiple approval policies. Policies are based around the concept of organizations. An organization is a set of project maintainers. Various types of thresholds can be configured for organizations and boolean conditions can be used to combine policies. Policies can be configured to apply to specific file paths and/or git branches. Refer to the customization documentation for more information about policies.

Checks-Out has optional support for automatic tagging of merges. Tags can configured based on timestamp or semantic versioning.

Checks-Out has optional support for automatic merging of pull requests when all status checks have passed.

Checks-Out has changed the default behavior when new commits are added to a pull request. By default only comments that have a later timestamp than the latest commit are processed by Checks-Out. There is a configuration property to use the original LGTM behavior which is to consider all comments on a pull request.

Usage

.checks-out file

Each repository managed by Checks-Out must have a .checks-out file in the root of the repository. This file provides the configuration that Checks-Out uses for the repository. The configuration file is described in detail in the customization section of the online documentation.

This repository has an .checks-out file that you can use as an example. It is likely that you will need a simple .checks-out file, so you can use the following template:

approvals:
[
  {
    match: "all[count=1,self=false]"
  }
]

MAINTAINERS file

Each repository managed by Checks-Out should have a MAINTAINERS file that specifies who is allowed to approve pull requests. The format of the file is described in the maintainers section of the online documentation. Here is a sample MAINTAINERS file to get you started:

github-org repo-self

Build
