Here's my preferred leisure project in C++. I aim to create a small, imperative utility language for personal usage. Also, I dislike *nix shell script syntax so here I am.
Pre-Notes:

Nicely done 🙂

Oh nice! I've starred the repo -- did you follow a book like Crafting Interpreters or anything like that?

I've loosely followed the Crafting Interpreters book and lurked within the Programming Languages Discord. Though my VM is not purely a stack one since it simulates a "base pointer" per function's stack frame so local variables are handled properly.

Definitely going to be taking a look at your impl -- that's kinda what I'm working on right now too

I've added a semantic analyzer which detects undeclared names, return types vs. enclosing procedure result types, and some expression type checking.
It's now passing test sources up to test_3e

Currently working on adding native functions
now it's time to build and test even more...
half anchor
Native functions (added to the VM instance in native code) now can be pre-declared as "used". Now I can print numbers.

Will start working on while loop support. The only regret I have is making my IR steps 1 to 1 against my bytecode, so I'll have to refactor more of the codegen for complex reasons. 
half anchor
After some fixes for codegen, I can say that while loops are starting to work. Test 5 passes now, but I'll add more complex tests later.

what are those trailing commas for in the arguments?
half anchor
I'm on the fence about this design decision. Trailing commas look a bit weird coming from most other languages, but I was trying to get a minimal program running at first, resulting in shortcuts being taken. But I may enhance the parser later to have better error messages too.
half anchor
Got a simple array iteration to work, and this program running in the image is a debug build.

very nice!

After ~6 hours of on/off refactoring and debugging, I have got my compilation logic and VM to handle imported procedures from other "TUs". It is 4am rn, time to crash out. 😴
My biggest regret was hardcoding things to only address one source file in any program in the toy language.

I'm on hiatus for now (just passed summer midterms). I'll be back working on this possibly next week or so, and when I do, I'll continue by the roadmap.

very cool!

working on my AST for my c compiler

Just returned to the project this morning and managed to remove trailing commas from the syntax.
Will update the main branch later

yey

Up next if I can find a lull in my summer homework...
Improve parser error messages to notify what are "expected" tokens for certain bits of syntax (0.7.1b)

Pretty good code

i went through the code for your interpreter. looks very organized and clean to me! good job so far

Thanks 🙂
I'm on hiatus for this one currently since I've gotten sidetracked into implementing a toy minecraft server. Though I do intend to finish the roadmap eventually.

sounds like a fun project too

It is... as long as I keep my goals simple. The protocol has over 200 packet types, over a dozen encoded types, and uses a very stateful connection.
