Indian high schooler here, currently prepping for JEE, thought itd be nice to share here.
Three years ago in 9th/10th grade I got a knack for coding, I taught myself and made a custom compiler with LLVM to try to learn C++. So I spent a lot of time learning LLVM from the docs and also C++. It's not some marvelous piece of engineering,
I designed the syntax to be a mix of C and what I wished C looked like back in 9th grade.
It has:
- Basic types like bool, int, double, float, char etc. with type casting
- Variables, Arrays, Assign operators & Shorthands
- Conditionals (if/else-if/else), Operators (and/or), arithmetics (parenthesis etc)
- Arrays and indexing stuff
- C style Loops (for/while) and break/continue
- Structs and dot accessing
- extern C interop with the "extern" keyword
- Emscripten and WASM, as I also had to make it run on my demo website
- Learning typescript and all for the website (lol)
- Custom parser with basic error reporting and Semantic analysis was a PITA for my undeveloped brain (I was 15)
- Learning LLVM from the docs
- Testing is a very important aspect of making software, I skipped it - big regret
- Learning how computers interpret text
- Programming in general was a new tour for me
- I appreciate unique_ptrs and ownership
Its on my github and there's a link to my web demo (https://vire-lang.web.app/), it might take some time to load the binary from firebase.
Very monolithic, ~7500 lines of code, I’d really appreciate any feedback, criticism, or pointers on how I could’ve done this better.
