Allows to manipulate crontab from comfortably from ruby code. You can add/modify/remove (aka CRUD) named crontab entries individually with no effect on the rest of your crontab. You can define cron entry definitions as standard text definitions ‘10 * * * * echo 42‘ or using Hash notation {:minute=>10, :command=>’echo 42’} (see CronEntry ::DEFAULTS) Additionally you can parse cron text definitions to Hash.
From other features: CronEdit allows you to make bulk updates of crontab; the same way you manipulate live crontab you can edit file or in-memory definitions and combine them arbitrarily.
Class methods offer quick crontab operations. Three examples:
CronEdit::Crontab.Add 'agent1', '5,35 0-23/2 * * * echo agent1'
CronEdit::Crontab.Add 'agent2', {:minute=>5, :command=>'echo 42'}
CronEdit::Crontab.Remove 'someId'
Define a batch update and list the current content:
cm = CronEdit::Crontab.new 'user'
cm.add 'agent1', '5,35 0-23/2 * * * echo agent1'
...
cm.add 'agent2', {:minute=>5, :command=>'echo 42'}
cm.commit
p cm.list
see CronEdit::Crontab class for all available methods
You can do a bulk merge (or removal) of definitions from a file using CronEdit::FileCrontab
fc = FileCrontab.new 'example1.cron'
Crontab.Merge fc
p Crontab.List
Crontab.Subtract fc
Similary to CronEdit::FileCrontab you can you also CronEdit::DummyCrontab for in-memory crontabs. Above all, you can combine all three crontab implementations Crontab, FileCrontab, DummyCrontab arbitrarily.
