Re: python's twisted deferred : how to in Lua?

["Francisco Sant'anna" <francisco.santanna@...>]

Hello,
You might also look at LuaGravity.
This mechanism looks like a `link` between two Lua functions:

function a ()
    return 1
end
function b (v)
    return v * 2
end
function c (v)
    print(v)
end
link(a, b)
link(b, c)
a()

By executing `a`, when it returns 1, `b` is triggered receiving that value.
Then `b` returns 1*2 and `c` is called, printing 3.

Hello,
the twisted python framework provides a very elegant mechanism to do
asynchronous programming, through so called 'deferred'.
See doc here: http://twistedmatrix.com/documents/current/core/howto/defer.html

I was wondering if there's support for this programming style in the
language itself (looking at the doc I don't think so), or if
something similar is provided by Lua frameworks.

thanks,
