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
  banner "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
