[OSC_dev] [ANN] Lua bindings for oscpack

[Gaspard Bucher]

Hi everyone,

I just released "osc", a Lua library to pack/unpack OSC messages. The
library is based on oscpack by Ross Bencina.

Compared to oscpack, this library adds support for sending key/value pairs
(hash). If anyone thinks adding Hash support to oscpack is interesting
outside of Lua, I can send a patch to Ross. Type values for a Hash are: '{'
(start hash), '}' (end hash). Encoding is simple it simply alternates
string (for key) and value type: {sfsfss}.

The library is really simple and has just two methods: pack and unpack.

Cheers,

Gaspard

Hi Gaspard,

Looks cool. Does it support OSC bundles?

Cheers,

Ross.

Hi Ross,

No, bundles are not supported. I could easily add support for them if
needed.

Lua code without bundles:

local url, ... = osc.unpack(data)
local fun = map[url]
if fun then fun(url, ...) end

This is the best API I could come with that is stateless, simple and avoids
the overhead of creating temporary tables with message arguments:

local timestamp = osc.unpackBundle(data, function(url, ...)
local fun = map[url]
if fun then fun(url, ...) end
end)
-- commit all changes, using timestamp or not.

packBundle would receive a list of messages and a timestamp.

Do you feel I should implement this ?
