Chronis

As cron expressions are not easy to understand and write, Chronis will help you define cron jobs using natural language and will generate crontab files for you.

This will also allow you to verison control your cron job definitions in a structured file (YAML) and generate crontabs during your deployment process.

Usage

Prerequisites

PHP 7 is required for Chronis to run.

Installing

To include Chronis in your PHP project:

composer require mylk/chronis

You can also install Chronis as a global command and not as a project's dependency:

composer global require mylk/chronis

Run

To execute Chronis and get some help:

vendor/bin/chronis list

To execute Chronis when installed as a global command, first make sure that $HOME/.config/composer/vendor/bin/ is in your system's $PATH. Then you can execute Chronis from anywhere:

chronis list

Then, you will need to have a yaml file to define your cron jobs. You can begin with this as an example.

To dump the crontab:

vendor/bin/chronis dump --config=YOUR_YAML_FILE_PATH

To export the crontab:

vendor/bin/chronis export --config=YOUR_YAML_FILE_PATH --output=my_crontab

The --output argument is not necessary. If not given, the crontab will be exported to a file named crontab in the current directory.
