A small, self-hosting C interpreter written in C, inspired by and largely based on c4, accompanied by a step-by-step tutorial series (in English and Chinese) explaining how it is built. It is primarily an educational project for learning how interpreters and compilers work.

Use cases

• learn how to write a C interpreter
• understand how compilers and interpreters work
• study a small self-hosting interpreter codebase
• follow a step-by-step compiler construction tutorial
• learn lexing and recursive descent parsing
• build a simple virtual machine in C

When to choose

• you want to learn interpreter/compiler fundamentals from readable, minimal code
• you prefer learning by reading a guided tutorial alongside the source
• you want a small self-hosting C interpreter to experiment with

When to avoid

• you need a production-grade C compiler or interpreter
• you need full C standard compliance or performance
• you want a maintained tool for running C code in real projects
