alveelan
A programming language for Bangla-speaking kids. Bangla keywords, digits and error messages, compiled to native code through LLVM.
source ↗2026
What it is
Most children in Bangladesh meet programming through English keywords. In alveelan the whole language is Bangla: ধরি declares a variable, যদি / নাহলে branch, যতক্ষণ loops and দেখাও prints. Numbers can be written with ০–৯, and programs answer in ০–৯ too.
How it works
The compiler is written in Rust and goes from source to a native executable:
- Lexer: Bangla keywords, Unicode identifiers, and Bangla digits normalised to ASCII.
- Parser: recursive descent with precedence climbing.
- Semantic analysis: scopes, types and function signatures, with errors written in Bangla.
- Code generation: LLVM IR through inkwell, then an object file linked with a tiny C runtime that prints numbers in Bangla digits.
Highlights
- Every example program is compiled and run in CI, and its output is checked against expected files.
- Errors name the variable or type in Bangla and give the line number in Bangla digits.
- Builds against LLVM 18–21 through Cargo features.
