timer

Easy timers in Lua. Spiritual successor to kikito's cron.lua

Public domain! Who needs an IP anyhow?

Usage

Can be mostly used as a drop-in replacement for kikito's cron.lua, but that misses the biggest benefit, which is the timer library itself managing timers, including discarding expired timers:

timer.after(time, function, ...) -- runs once after time
timer.every(time, function, ...) -- runs repeatedly, every time

timer.update(delta)              -- increment, run functions, discard expired..

A timer can be excluded from timer.update, in which case it must be manually updated:

local my_timer = timer.every(time, function, ...)
my_timer.manual = true

my_timer:update(delta)

timer.update returns a table of expired timers. Example:

local my_timer = timer.after(time, function, ...)

local expired = timer.update(delta)
if expired[my_timer] then
  -- idk, whatever you needed
end

Timers can have their time set to a new value with my_timer:reset(time). If nothing is passed, they will be set to 0.

Incompatibilities / Changes from kikito's cron.lua:

Number values are not checked or restricted.
Different error message for callback not being callable.
If a one-time timer is run by timer.update, it will no longer be updated by timer.update, even if reset.

Ideas / Tasks

Make an import/export format and add save/load functions - resumable timers.
- Make it possible to save/load with a unix timestamp. (Dangerous.)
Make an access function get_run_time
Make functions optional
