The official C0 and O0 format standards (Chinese):

• C0 spec & homework description: https://github.com/BUAA-SE-Compiling/c0-handbook
• O0 spec: https://github.com/BUAA-SE-Compiling/c0-vm-standards
• O0 virtual machine: https://github.com/BUAA-SE-Compiling/c0-vm-cpp

Usage

# Parse and compile a c0 source file to `out` as c0 binary
$ chigusa <file> -o <output_file>

# Compile the file as c0 assembly
$ chigusa <file> -s -o <output_file>
# or
$ chigusa <file> --emit s0 -o <output_file>

Chigusa's implementation

Chigusa uses a handwritten recursive-descending parser to parse C0 programs.
