LuckyCli

A Crystal library for creating and running tasks

Installing the CLI

  1. Install homebrew
  2. Run brew tap luckyframework/lucky
  3. Run brew install lucky

Run which lucky from the command line to make sure it is installed.

If you're generating a Lucky web project, install the required dependencies. Then run lucky init {project_name}

Using LuckyCli in a non-Lucky web app

Add this to your application's shard.yml:

dependencies:
  lucky_cli:
    github: luckyframework/lucky_cli

Create a file tasks.cr at the root of your project

require "lucky_cli"

# Using `lucky` from the command line will do nothing if you forget this
LuckyCli::Runner.run

Creating tasks

In tasks.cr

class App::SendDailyNotifications < LuckyCli::Task
  # What this task does
  summary "Send notifications to users"

  # Name is inferred from class name ("app.send_daily_notifications")
  # It can be overriden if desired:
  #
  #    name "app.send_daily_notifications"

  def call
    # Code that sends notifications to all your users
    puts "Sent daily notifications!"
  end
end

# LuckyCli::Runner.run is below this

This will create a task that can be run with lucky app.send_daily_notifications. The name is inferred from the name of the class unless explicitly set with name.

You can see all available tasks by running lucky --help

Contributing

  1. Fork it ( https://github.com/luckyframework/lucky_cli/fork )
  2. Create your feature branch (git checkout -b my-new-feature)
  3. Install docker and docker-compose: https://docs.docker.com/compose/install/
  4. Run script/setup to build the Docker containers with everything you need.
  5. Make sure specs pass: script/test. This will take a long time.
  6. Commit your changes (git commit -am 'Add some feature')
  7. Push to the branch (git push origin my-new-feature)
  8. Create a new Pull Request

Testing Deployment to Heroku

Testing deployment to Heroku is skipped locally by default. The easiest way to run the deployment tests is to push up a branch and open a PR. This will run tests against Heroku to make sure deployment is working as expected.

If you want though, you can also test deployment locally:

  1. Sign up for a Heroku account and install the CLI.
  2. Run heroku authorizations:create --description="Lucky CLI Integration Tests".
  3. Grab the token from that command and put it in the generated .env file.
  4. Change RUN_HEROKU_SPECS from 0 to 1 in the .env file.
  5. Run script/setup to rebuild the Docker container
  6. Run script/test to test everything, or run script/test specs/integration/deploy_to_heroku_spec.cr
