Pineal
An engine for graphic live-coding on an audio stream, something between
Fluxus and Processing,
but in Python!
(ok that's not true, it was in Python, now it is mainly in a
pythonic Lisp dialect)
Example
(osc-source amp "/amp")
(osc-source bass "/bass")
(osc-source high "/high")
(stroke-weight 4)
(on my-layer
(fx [(scale (amp 1 1))]
(draw my-layer))
(fx [(scale (amp 4))]
(pwired 4 [0 1 1 1])
(psolid 4 [0 0 0 0.1]))
(fx [(scale (bass 2))]
(pwired 4 [0 1 0 1])
(psolid 4 [0 0 0 0.1]))
(fx [(scale (high 4))]
(pwired 4 [1 1 1 1])
(psolid 4 [0 0 0 0.1])))
(draw my-layer)

Warning
This project is heavily in development. You can use it, I use it in "production" (coding at parties). But be prepared to continuous and unexpected changes in syntax (it's getting even more functional) and new features that randomly appear or disappear.
In case of doubt you can look at sample.hy
or the examples/
folder, they
should always work.
