Pseudocode Converter: Convert Code to IB‑Compliant Pseudocode

Overview

Pseudocode Converter is a web application that transforms source code into standardized, IB‑compliant pseudocode suitable for teaching, assignments, and exam preparation in Computer Science. It helps students and instructors quickly produce clear, consistent pseudocode from familiar programming languages.

Features

IB‑style pseudocode conversion for Python and Java
Standardized keywords and block structure for readability and assessment
Coverage for core control flow: conditionals, loops (FOR / WHILE / REPEAT–UNTIL)
Procedures/functions, arrays/lists, and boolean expressions
Instant output ready to copy into reports, worksheets, or exam responses

Tech Stack

Next.js (UI) + TypeScript
AST‑based conversion pipeline that analyzes code structure
Fully serverless: static hosting on Cloudflare Pages; no backend; conversion runs client‑side in the browser
Modular, self‑authored npm libraries for language support:
- java2ib — Java → IB‑style pseudocode (MIT)
- python2ib — Python → IB‑style pseudocode (MIT)
Cloudflare Pages deployment for fast, reliable delivery

Design & Architecture

Uses AST (Abstract Syntax Tree) analysis to understand control flow, declarations, and expressions before mapping them to IB‑compliant pseudocode
All parsing and conversion runs entirely in the browser (client‑side); input code is never sent to any server
Parsers are split into independent npm libraries to keep the main repo lean and extensible:
- java2ib: converts Java AST to IB‑style pseudocode
- python2ib: converts Python AST to IB‑style pseudocode
Both parser libraries are self‑authored in TypeScript and published under the MIT license
Why separate libraries?
- Extensibility: add new languages in the future without bloating the core project
- Maintainability: version, test, and release each parser independently
- Reusability: others can import the libraries directly in their own projects
- Licensing: both libraries are published under MIT for open use

How It Works

Paste Python or Java code into the editor.
Click Convert to generate IB‑style pseudocode via AST‑based parsing powered by the language libraries.
Review the output and copy it directly into your assignment or notes.
If something looks off, report the case so it can be improved.

IB Pseudocode Alignment

Follows widely used IB Computer Science pseudocode conventions (keywords, block structure, indentation)
Emphasizes clear naming and language‑agnostic constructs
Conservative handling of edge cases to avoid ambiguity
School‑specific differences can be accommodated over time
