These are well-known open source PHP libraries — from small utilities to large frameworks. Each one represents the kind of real-world codebase Pext is designed to handle.
PHP dependency manager. Resolves, downloads, and autoloads packages across the PHP ecosystem.
Exercises file system, process execution, and HTTP at scale.
PHP testing framework with assertions, mocking, data providers, and code coverage reporting.
A flagship target — transpiling PHPUnit itself would validate nearly every language construct Pext supports.
PHP API extension for DateTime — a widely adopted date/time manipulation library in the Laravel ecosystem.
Heavy use of traits and magic methods. Requires full DateTime runtime parity.
Arbitrary-precision arithmetic library built on BCMath. Immutable value objects for integers, decimals, and rationals.
No side effects, no I/O — pure computation. Ideal for showcasing runtime correctness.
Computes and renders the difference between two strings or arrays using Myers and Longest Common Subsequence algorithms.
Pure OOP with no web or extension dependencies — a clean, self-contained target.
Exports PHP variables for visualization. Used internally by PHPUnit for assertion output formatting.
Exercises type juggling and reflection — core Pext strengths.
