library0.1.3jsnpmunverified

A transpiler that converts Processing (Java) source code to p5.js (JavaScript). Current stable version 0.1.3 transforms syntax like void functions, size(), and Processing APIs into p5.js equivalents. Released as an early-stage tool with TypeScript type declarations. Suitable for migrating Processing sketches to the browser. Does not cover all Processing features; manual adjustments may be needed.

Named export; TypeScript types included.

Transpile a simple Processing sketch with setup() and draw() to p5.js code.

import { transformProcessing } from 'processing-to-p5js'; const processingCode = ` void setup() { size(400, 400); background(220); } void draw() { ellipse(mouseX, mouseY, 20, 20); } `; const p5jsCode = transformProcessing(processingCode); console.log(p5jsCode);

Debug
Known issues
gotchatransformProcessing replaces Processing built-in functions like size(), background(), ellipse() but does not handle all Processing APIs.
fix
Review output for untranslated functions and manually implement p5.js equivalents.
affects: >=0.1.0
gotchaThe package does not transform Java language features beyond basic syntax (e.g., classes, generics, libraries).
fix
Rewrite complex Java patterns manually.
affects: >=0.1.0
deprecatedtransformCode() function is experimental and may change in future versions.
fix
Prefer transformProcessing() for full transformation.
affects: 0.1.0
Errors
Common errors & fixes
TypeError: (0 , processing_to_p5js.transformProcessing) is not a function
Incorrect import due to mistaken belief that package has default export.
fix
Use named import: import { transformProcessing } from 'processing-to-p5js'
Cannot find module 'processing-to-p5js' or its corresponding type declarations.
Missing installation or TypeScript not configured for ESM.
fix
Run 'npm install processing-to-p5js' and ensure 'moduleResolution' is 'node16' or 'bundler' in tsconfig.json.
