Using Janet In Monolith
This is a general overview for using Janet in Monolith.
Janet was introduced as an alternative language interface to Scheme. It's still in the early stages, but has proven itself to be a very promising language with a flexible C API.
Here is just enough code to be able to evaluate runt code to produce an audio file:
(monolith/runt-loader) (def rvl monolith/runt-eval) (rvl "patchwerk nodes") (rvl "440 0.5 sine") (rvl "\"sine.wav\" wavout bdrop ps") (monolith/compute (* 44100 10))
TODO Patchwerk Plugins with Janet
Janet can be used to build dynamically loadable patchwerk plugins. This makes it easier to develop experimental DSP algorithms.
The code below shows how to make a simple sine wave generator in patchwerk, wrapped inside of a Janet function.
INSERT CODE HERE.
This can be built using the internal JPM utility included
From here, the node can be managed using some of the janet-patchwerk bindings, included in monolith. Monolith also supplies some glue functions that allow the node to interact with Runt code:

TODO Drawing With Janet
Most drawing operations are implemented as Janet functions, rather than scheme ones. This was done in order to practice using Janet.
Calling Janet from Scheme
Yes, Janet can be controlled from inside of Scheme. Isn't that just terrible? This combo is used when creating audio-visual things. Scheme handles most of the audio side and pages, while Janet is used to produce the graphics, using channels to talk to one another.
First, Janet needs to be initialized using
From there, janet code can be evaluated using
TODO Using Jex
JEX, or Janet EXecute, is a runt word that allows a Janet function to be triggered from Patchwerk. Multi-threaded support in Janet is tricky, so this only works in offline mode.
