cepl VS ok

CEPL is great for something more advanced.

https://github.com/cbaggers/cepl (in Common Lisp - graphics and translating to GLSL shaders)

https://github.com/cbaggers/cepl There are a lot of videos of this being used, link is in the project's README.

I used to write software for image generators using GLSL and so I used to do some graphics projects using C, OpenGL, and GLSL. Later I discovered CEPL, which gave me a REPL to do GLSL-like graphics pipelines. That was an improvement but I don't find GLSL fun. But then I discovered April and APL in general and now I can dabble with image processing whenever I feel like it with minimal ceremony.

CEPL: A lispy and REPL-friendly Common Lisp library for working with OpenGL\ (8 comments)

If I was doing a course in computer graphics today I would sidequest with April and CEPL.

This - https://github.com/JohnEarnest/ok - can also be used sometimes...

If you want to try out K, there are some open source implementations, like John Earnest's oK which has a REPL and a calculator-like interface for mobile phones with a charting feature.

and have the programmer use the word "barchart", they instead prefer to use the definition itself. The word "barchart" has a specific meaning (here, an ascii "bar chart" of 0s and 1s, showing the relative sizes of the values of input array x), but "{x>\:!|/x}" might be useful for more than just bar charts. This idiom contains smaller idioms like "count til max" (!|/) which in turn contains "max" (|/).

Being able to see the code makes it easier to explore and tweak to your specific needs. But more importantly, there are no "official" names for concepts like "count til max". That's just my personal name for it. A python programmer would call it "range". You could come up with your own name for (!|/) that makes perfect sense to you. But that name will probably be longer than its definition, and less flexible.

check out oK[0] by John Earnest, who is the author of the content of this post

it is well-written manual and is a great jumping off point

there is a k-enthusiast element.io server[1] where you can ask any question you like. folks are friendly!
