# 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](https://github.com/kikito/cron.lua),
|
|
but that misses the biggest benefit, which is the timer library itself managing
|
|
timers, including discarding expired timers:
|
|
|
|
```lua
|
|
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:
|
|
```lua
|
|
local my_timer = timer.every(time, function, ...)
|
|
my_timer.manual = true
|
|
|
|
my_timer:update(delta)
|
|
```
|
|
|
|
`timer.update` returns a table of expired/unexpired timers. Example:
|
|
```lua
|
|
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.
