Cucu, a tiny module to schedule repeated execution of ( single process ) methods/tasks.
$ npm install cucu [-g]require:
var Cucu = require( 'cucu' );$ cd cucu/
$ npm testCucu()
// or
new Cucu()/*
* The current number of running tasks.
*/
Cucu.running : Number
/*
* Task table, an obj/hash containing tasks by id/key/name.
*
* A table entry for a task named 'id' is an obj/hash like:
*
* ttable[ 'id' ] = {
* id : 'id'
* , fn : fn
* , interval : Number
* , args : Array
* , scope : Object
* , status : Number | Object
* , repeat : Number
* // timestamps for task start, current iteration and task stop/halt/end.
* , stime : Number
* , itime : Number
* , etime : Number
* // get task time infos
* , timetable : Function
* // Cucu method shortcuts
* , run : Function
* , stop : Function
* , del : Function
* };
*
* NOTE: Every entry contains shortcuts to Cucu#run, #stop and #del methods, already
* curried with their own ids. For example, if exists a task named 'dumb' in the task
* table, you could also use the methods below, for running, stopping or deleting an
* existing task:
*
* Cucu.ttable.dumb.run( [ Number interval [, Array args [, Number times ] ] ] ) : Number
*
* Cucu.ttable.dumb.stop() : Array
*
* Cucu.ttable.dumb.del() : Array
*
*

Cucu.ttable : ObjectArguments within [ ] are optional.
/*
* Add a task; a task will be added only if there is no other task already running
* with this name/id.
* It returns 1 if task is added, 0 if the same task id is already running, -1 if
* an error occurs.
*/
Cucu#add( String id, Function fn [, Array args [, Object scope [, Number interval ] ] ] ) : Number
/*
* Run a task by name/id. Optionally you can specify interval, function arguments and
* the max number executions for a task.
* It returns 1 if task is started, 0 if the task is already running, -1 if no task
* exists.
*
* NOTE: if 'times' option is specified, the scheduled function 'fn' will get, as the
* first argument, a function to execute when task will be done.
*/
Cucu#run( String id [, Number interval [, Array args [, Number times ] ] ] ) : Number
/*
* Remove tasks by id/name; a task will be removed only if it is not currently running.
* It returns a list of ids/names for all the removed tasks.
*/
Cucu#del( String id | Array ids ) : Array
/*
* Stop a running method/task by name/id.
* It returns a list of ids/names for all the stopped tasks.
*/
Cucu#stop( String id | Array ids ) : Number
/*
* Start all non-running tasks.
* It returns the total number of non-running tasks started.
*/
Cucu#awake() : Number
/*
* Halt all running tasks.
* It returns a list of ids/names for all the stopped tasks.
*/
Cucu#halt() : Array
/*
* Stop and delete all tasks.
* It returns the list of ids/names for all the removed tasks.
*/
Cucu#flush() : Array
/*
* Get a list of names/ids for all the currently active/running tasks.
*/
Cucu#active() : Array
/*
* It returns the total number of tasks.
