webc is a compiler for C99 that outputs WASM and a JS runtime for both servers and browsers. The goal of webc is to create a runtime similar to native C that can be run either in the browser or on the server (with Node.js, Bun etc.) with features such as a virtual filesystem, C style error handling (errno), and support for signals from JavaScript.

Currently in active development

Installation

The only requirements for webc is having Go installed on your system, other than that you can install it with:

git clone https://github.com/grqphical/webc
cd webc
make build

Usage

Simply run the compiler with a C file and it will output a WASM binary as well as an HTML/JS file to run the program

You can use -s to create a server runtime that can be run with Node.JS or a similar JS runtime

You can use the -o flag to change where the output binary will be.

Features/Roadmap

• Main function
• Integer variables, arthimetic, and variable modification
• Floating point variables, arthimetic, and variable modification
• Character variables, arthimetic, and variable modification
• Constant variables
• Long (64 bit Integer) variables, arthimetic, and variable modification
• Unsigned Integer/Long variables, arthimetic, and variable modification
• If/Else-If/Else Statements
• For/While loops
• Functions
• Preprocessor (include, define, ifdef, etc.)
• Dynamic Memory (malloc/free)
• Structs, Unions, Typedefs
• Static variables

Contributions

Any contribution is welcome, just make sure to run make format before you commit to ensure the code style remains consistent
