The "event" library is meant to
|
||
|
|
mirror that of OpenOS in some ways,
|
||
|
|
while being distinct in others, such
|
||
|
|
as its optional nature.
|
||
|
|
|
||
|
|
The event library returns a function,
|
||
|
|
which you then call with the process
|
||
|
|
NEO table, which then actually gives
|
||
|
|
the event table, after wrapping
|
||
|
|
the neo.requestAccess function in
|
||
|
|
order to ensure that events are
|
||
|
|
caught during that loop (as the only
|
||
|
|
direct event-loop in the kernel
|
||
|
|
API, with requireAccess using the
|
||
|
|
requestAccess in your NEO table).
|
||
|
|
|
||
|
|
This amounts to:
|
||
|
|
|
||
|
|
local event = require("event")(neo)
|
||
|
|
|
||
|
|
This is what's in the event table:
|
||
|
|
|
||
|
|
listen([p1, ] cb): This has 2 forms.
|
||
|
|
It can be first-arg string, second
|
||
|
|
callback, or just a callback.
|
||
|
|
This is determined by the type of
|
||
|
|
the second argument.
|
||
|
|
If it's a function, then that - the
|
||
|
|
callback - is only called for
|
||
|
|
events of the type in the first
|
||
|
|
argument.
|
||
|
|
Otherwise, the callback is the 1st
|
||
|
|
argument, and the function is the
|
||
|
|
second argument.
|
||
|
|
|
||
|
|
ignore(cb): Deletes a callback. Yes,
|
||
|
|
this works even if a filter was
|
||
|
|
added onto it.
|
||
|
|
|
||
|
|
pull(...): Waits for an event whose
|
||
|
|
first parameters are.
|
||
|
|
Rather than using this for sleep,
|
||
|
|
you should use runAt or sleepTo.
|
||
|
|
|
||
|
|
runAt(time, func): At a given uptime
|
||
|
|
in os.uptime() units, runs func.
|
||
|
|
|
||
|
|
sleepTo(time[, earlyWake]): Runs
|
||
|
|
until either earlyWake() returns
|
||
|
|
true (if given), or os.uptime() >=
|
||
|
|
the time given, using a timer.
