py4cl2 VS farolero

I... recently got that working: https://github.com/digikar99/py4cl2/tree/master/cffi - Yes, CFFI! Yes, passing CL array data by reference!

I ended up using a fair bit of matplotlib through college and with colleagues. I too don't want to use python, but I also don't like throwing away its libraries, and I'm too lazy to invest in other* plotting ecosystems. In effect, I use up using matplotlib through py4cl/2.

Note that it is not my aim to replace the python ecosystem; I think that is far too lofy a goal to be of any good. My original intention was to interoperate with python through py4cl/2 or the likes, but felt that one needs a Common Lisp library for "small" operations, while "large" operations can be offloaded to python libraries through py4cl/2.

Python: Blender and Panda3D (game engine used for Disney's Toontown way back when) are both scriptable with Python. I've been able to successfully call Panda from Py4CL2 (thanks digikar for the help with that), but I have not tried with Blender yet. I think it's doable.

While you are at it I may as well mention https://github.com/digikar99/py4cl2

If performance is absolutely not a concern, then third option is using python libraries through py4cl/2. To put it differently, if calling python from lisp is not the bottleneck, then this is a feasible option.

py4cl2 (not py4cl!) author here. From the v2.9.0 docs:

py4cl and py4cl2 represent a fairly pragmatic example of method 1, using an OS child process to communicate back and forth with your python code. Python is fairly popular and well-enabled with libraries, so you can delegate things to python that leverage those libraries.

If you can structure your code so that data de/serialization is not a bottleneck, then you could access the python libraries using py4cl/2.

You can use this library to get CL-style conditions and restarts in Clojure: https://github.com/IGJoshua/farolero

True, the CL REPL is more useful than the Clojure REPL, but CL has a 20-30 year head start in development. Plus, Clojure was developed as a hosted language, and runs on .NET, Javascript, JVM, and even Dart (in-progress).

Since exceptions are quite deeply integrated into those platforms (as opposed to conditions), it has "bled through" to the Clojure APIs, and, in turn, REPL.

Folks have written a CL-style condition/restart library for Clojure (https://github.com/IGJoshua/farolero) too.

conditions/restarts are also a possibility https://github.com/IGJoshua/farolero

Someone added conditions/restarts to Clojure: https://github.com/IGJoshua/farolero

It does allow errors to be caught by the Repl and just.hkw to handle them.

This is interesting tool[1] that allows much the same with Clojure

https://github.com/IGJoshua/farolero This uses derive hierarchies to enable general error handling.
