thirteen-letters VS cling

Note that Common Lisp doesn’t require functional programming. Mutation, side effects, etc. are fine. I just write imperative code for the most part.

My code was quick and dirty, so I don’t think anyone will learn anything from it, but it’s here: https://github.com/jaredkrinke/thirteen-letters

Thirteen Letters is a web-based, competitive word scramble game I made for the Lisp Game Jam (Spring 2023) [0].

The gameplay isn't novel, but it's a multiplayer browser game that's written in 100% Common Lisp (cf. the source code [1]). The front end uses Parenscript, Spinneret, and cl-css to translate s-expressions to JavaScript, HTML, and CSS, respectively. The back end is built using the Hunchentoot web server, Hunchensocket for WebSockets, and yason for JSON, running on SBCL.

I'm fairly new to Common Lisp, so I'm not qualified to dispense advice, but I found having a REPL on the live service to be convenient for monitoring activity, toggling settings, and fixing minor bugs on the fly. It's a lot of fun for hobby projects, although I'd be much more cautious with anything important--I definitely broke the live service a few times by not being careful! I posted a more thorough braindump elsewhere [2].

Let me know what you think! I'm happy to answer any questions. I'll play for a while, to hopefully give people a moderately worth opponent :)

> 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?

not to mention ruby, python, php, lua

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

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.

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.
