CLang

The CLang is an interpreter-based implementation of C written in TypeScript.

It supports the following features of C:

Primitives: (unsigned) char, short, int, float, double, long
Derived types: strings and arrays (both statically/dynamically allocated)
Function declaration/application, Variable declaration/initialization/assignment
Operators: arithmetic (<. <=. ==, +, -, etc.), logical (&&, ||), variable address (&), assignment(=, +=, /=, etc.) sizeof, pointers
Loops: while, for, do while
Conditionals: if else, switch case statements
Memory management: pointers, pointers-to-pointers, dynamic memory allocation with malloc
IO: printf, print_stack, print_heap

Usage

To build:

git clone https://github.com/DavidVin357/c-lang.git
cd c-lang
npm i
npm run build

To use the interpreter with CLang Frontend, run npm link

Alternatively, you can also try out the CLang in its playground at https://DavidVin357.github.io/c-frontend

Run npm test to see the execution of the jest tests on samples in tests/test.ts
