cron2english

Cron2English is a Ruby library for turning crontab schedules into English text.

It is roughly a Ruby port of Sean Burke's crontab2english Perl script, except its interface is a Ruby method rather than an executable, and it parses only time specs, not all the other things you might find in a crontab (comments, variable definitions, and the commands to run).

You can convert a time spec to English like so:

english = Cron2English.parse("40 5 * * *")

This will yield an array of strings, in this case the following:

["5:40am", "every day"]

These strings are chosen so as to sound vaguely human if you say:

Cron2English.parse("40 5 * * *").join(" ")

Cron2English understands just about anything you'll find in a crontab, including non-POSIX extensions. It can parse:

• 1-20/3 * * * *
• 1,2,3 * * * *
• 1-9,15-30 * * * *
• 1-9/3,15-30/4 * * * *
• 1 2 3 4 mON
• 1 2 3 4 mON-fri
• 1 2 3 jan 5
• 1 2 3 jan-apr 5
• @reboot
• @yearly
• @annually
• @monthly
• @weekly
• @daily
• @midnight
• @hourly
• */3 * * * *
