cling VS mal

> The repl driven workflow is amazing and the lisp images are rock solid and highly performant.

do people not realize that basically everything vm/interpreted language has a repl these days?

https://pub.dev/packages/interactive

not to mention ruby, python, php, lua

hell even c++ has a janky repl https://github.com/root-project/cling

Interactive C++ with Cling, https://blog.llvm.org/posts/2020-11-30-interactive-cpp-with-cling/, https://github.com/root-project/cling/, Relaxing the One Definition Rule in Interpreted C++, https://dl.acm.org/doi/10.1145/3377555.3377901 (PDF: https://www.researchgate.net/publication/339463915_Relaxing_the_one_definition_rule_in_interpreted_C)

Want to see your mind blown? Check out cling, a (sort of) C and C++ interpreter (it's a REPL). Or the work in progress, live-developed clauf, a real C interpreter.

Cling: https://github.com/root-project/cling

Wanting to just test pure c or c++ functions that are hardware independent -> (solution that I'm using): cling just in time compiler, gives a shell that you can just experiment with C++ expressions

C++ source cannot contain a shebang, but you can make them executable with binfmt-misc, and have the kernel pass them to a C++ interpreter such as Cling upon execution. Pretty much the same as running Python or Bash scripts.

>Would be interesting to see how the interpreter works actually...

It's quite easy to see, there are interpeters for Lisp in like 20 lines or so.

Here's a good one:

https://norvig.com/lispy.html

(It has the full code in a link towards the bottom)

There's also this:

https://github.com/kanaka/mal

Here is one implementation of a lisp (mal specifically) in matlab: https://github.com/kanaka/mal/blob/dcf8f4d7b9cf7b858850a04a0...

Only 260 lines of code, pretty concise :)

have a look at the crafting interpreters book, plus make a lisp (lisp is a great first language to make a compiler/interpreter for, just google "lisp compiler/interpreter" and you'll find lots of resources)

If you're really okay with the limitations of a tree-walk interpreter, you might want to check out MAL, which will teach you how to write a tree-walk interpreter for a LISP. The code for MAL has been translated to most popular languages, so you can work through the creation of an interpreter in the language of your choice. JLox would give you a bit more detail and a more complex language, but I'm not convinced that it's all that important.

Write a small programming language (lisp (https://github.com/kanaka/mal) or brainfuck) in C++ to learn the syntax more. This will teach you a lot about programming languages in general.

So I started some hobbyist game dev using Unity and realised that the full process of making a game has dependencies on a mass of lower-level skills including lighting virtual environments. As a hobbyist photographer I could see some useful analogies from lighting studios and other scenes

So I pivoted, and eventually made money, not from selling a game, but from developing tutorials about digital lighting. I was also able to contribute to a project at work that was making a product based on commercial games engine, not by actually coding it, but by helping to better estimate the costs of the asset generation required.

Coding Unity object scripts in C# also got me back into programming, and I went on to successfully build a self-hosting lisp interpreter following the Make a Lisp guidelines [0].
