Hubot Cron Events Plugin
This plugin is a generic event emitter scheduled using cron job. It's very similar to hubot-cron, but instead of sending messages it emits events.
This plugin can be very handy when combined with other plugins that will receive the emitted events.
There is another similar plugin named hubot-at-events that applies the same principle for one-time actions at given dates.
In your hubot directory:
npm install hubot-cron-events --save
If you use hubot-auth, the cron configuration commands will be restricted to user with the
But if hubot-auth is not loaded, all users can access those commands.
It's also advised to use a brain persistence plugin, whatever it is, to persist the cron jobs between restarts.
Commands prefixed by
.cron are here taking in account we use the
. as hubot prefix, just replace it with your prefix if it is different.
.cron version gives the version of the hubot-cron-events package loaded .cron <name> <period> <eventname> .cron <name> <period> <eventname> <tz> .cron <name> <period> <eventname> [<tz>] with param1=value1 .cron <name> <period> <eventname> [<tz>] with param1=value1 param2=value2 .cron <name> <period> <eventname> [<tz>] with param1=long value with spaces param2=value2 will create or update a job with unique identifier <name> the <period> has to match a valid cronjob syntax of type * * * * * if 6 items are provided (ie. * * * * * *), the first one will be the seconds the optional <tz> will be applied if provided if no eventname is provided, the job will not emit anything This also can be used to modify an existing job. If the tz and data are omitted they will not be changed Data params can be provided if you add 'with' and a list of attributions. There is a drawback, which is that in the current implementation, the values can't contain an equal sign ('=') example: .cron blah */5 * * * * * cron.message will emit a cron.message every 5 seconds that event requires 2 data params, room and message: .cron blah room = shell .cron blah message = tick tack or .cron blah */5 * * * * * cron.message with room=shell message=tick tack .cron start blah activates the job, which will run every 5 seconds .cron blah * * * * * modifies the job blah to run every minutes instead and it will emit the same event cron.message and it will keep the already set data note that modifying a job stops it, so it has to be restarted afterward .cron start blah now the job is active and will run every minute .cron status <name> tells if the job is running or paused .cron info <name> .cron show <name> gives the details about a job .cron list [<term>] lists all the jobs, or only the jobs with names matching <term> .cron stop <name> .cron pause <name> stops the job <name> .cron start <name> .cron resume <name> starts the job <name> .cron delete <name> delete the job <name> .cron <name> <key> = <value> sets a key-value pair in the job data if the key already exists, its value will be changed if you change the data for job that is currently running it will be stopped and restarted .cron <name> drop <key> removes a key-value pair form the job data this will also restart the job if it's running
Some events receivers are also provided for testing purposes:
cron.message requires data: - room - message it will just say the message in the given room cron.date requires data: - room it will tell the date on the room
npm install # will run make test and coffeelint npm test # or make test # or, for watch-mode make test-w # or for more documentation-style output make test-spec # and to generate coverage make test-cov # and to run the lint make lint # run the lint and the coverage make
