This is simple implementation of signal in Lua.
To install this library, simply copy/symlink src/signal.lua into your luarocks folder.
For example, installing signal library globally on Linux:
git clone https://github.com/VALAD47/signal.git
cd signal
sudo cp src/signal.lua /usr/share/lua/5.4/
First of all, require this library:
local signal = require("signal")
To create a signal, do this:
local foo = {}
foo.foo_signal = signal.new()
To create a connection to signal, do this:
foo.foo_signal:connect(f)
Where f is your function. This function can claim any arguments.
To fire a signal, do this:
foo.foo_signal:fire(...)
Where ... is any arguments you want.
When firing a signal, all functions that were connected to a signal will be called.
If you want to connection run in "multi-thread", you have to install library task, and set signal.MULTI_THREAD = true
