Minimal C subset → VHDL translator

git clone https://github.com/cmelnulabs/compi.git
cd compi && mkdir build && cd build
cmake .. && make
./compi input.c output.vhdl

• Recursive-descent parser with full operator precedence
• Control flow: if/else, while, for, break, continue
• Functions, structs, and arrays
• VHDL entity/architecture generation
• Multi-level error diagnostics
• 35 unit tests (GoogleTest)

./run_tests.sh    # Build and run all tests
./build_docs.sh   # Build documentation

src/       — Parser, lexer, codegen, error handler
tests/     — GoogleTest unit tests
docs/      — Sphinx documentation
examples/  — Sample C files

• No global variables
• No nested structs or arrays of structs
• Basic VHDL output (no optimization)

See ROADMAP.md for planned features and docs/ for full documentation.
