local_ci_plus

local_ci_plus improves Rails local CI for both developers and agents with parallel execution, fail-fast, resume, and plain output.

Add to your Gemfile:

gem "local_ci_plus"

Then run:

bundle install

local_ci_plus overrides ActiveSupport::ContinuousIntegration when it is loaded, so the default Rails bin/ci continues to work without changes. In plain/non-TTY mode, output is ASCII-only.

bin/ci

If your app does not already require the gem in bin/ci, run the installer generator:

bin/rails generate local_ci_plus:install

If you already have a bin/ci and want to patch it in place, run:

bin/rails generate local_ci_plus:update

If you want to edit bin/ci manually, add require "local_ci_plus" right after the boot file:

#!/usr/bin/env ruby
require_relative "../config/boot"
require "local_ci_plus"
require_relative "../config/ci"

-f, --fail-fast   Stop immediately when a step fails
-c, --continue    Resume from the last failed step
-fc, -cf          Combine fail-fast and continue
-p, --parallel    Run all steps concurrently
--plain           Disable ANSI cursor updates/colors (also used for non-TTY)
-h, --help        Show this help

Compatibility:
  --parallel cannot be combined with --fail-fast or --continue

By default, the first failing step is stored in tmp/ci_state. Set CI_STATE_FILE to override the path. To reset the resume point, delete the file.

Run tests:

bundle exec ruby -Itest test/continuous_integration_test.rb

Run linting:

bundle exec standardrb

Or run them both:

bin/ci --parallel

1. Bump the version in lib/local_ci_plus/version.rb.
2. Build and push:

gem build local_ci_plus.gemspec
gem push local_ci_plus-X.Y.Z.gem

This project is based off of ActiveSupport::ContinuousIntegration.

Many thanks to the Rails team for shipping the original work.
