picoc-web

PicoC interpreter compiled to WebAssembly for running C code in web browsers and Node.js.

Overview

This project ports PicoC to the web using Emscripten. PicoC is a very small C interpreter originally designed for embedded systems and scripting applications.

Usage

``javascript
import {
RunDefault,
RunWithInput,
RunWithOutput,
RunWithInputOutput,
RunInteractively,
} from "./Picoc";

// Test 1: RunDefault - Basic hello world
console.log("=== Test 1: RunDefault ===");
const helloCode =
#include
int main() {
printf("hello world \\n");
return 0;
};

const result1 = await RunDefault(helloCode);
console.log("Output:", result1);

// Test 2: RunWithInput - Read user input
console.log("\n=== Test 2: RunWithInput ===");
const inputCode =
#include
int main() {
char name[100];
printf("Enter name: ");
scanf("%99[^\\n]", name);
printf("Hello %s\n", name);
return 0;
};

const result2 = await RunWithInput(inputCode, "Alice");
console.log('Input: "Alice"');
console.log("Output:", result2.stdout);

// Test 3: RunWithOutput - Custom output handler
console.log("\n=== Test 3: RunWithOutput ===");
const countCode =
#include
int main() {
for(int i = 1; i <= 3; i++) {
printf("Count: %d\n", i);
}
return 0;
};
);

console.log(result.stdout); // "Hello, World!"
console.log(result.stderr); // Any error output
```
