Indian Highschooler 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, So I taught myself made a custom compiler with LLVM to try and learn C++. so I spent a lot of time learning LLVM from the docs and also C++ so its not some marvelous piece of engineering,

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

Some challenges I faced:

  - 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
  - Learning LLVM from the docs

Important Learnings:

  - 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

Github: <https://github.com/xeouz/virec> 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 pointer
