Phlex
Object-oriented views in Ruby
Phlex is a Ruby-based framework for building HTML and SVG views using object-oriented programming principles, offering a unique alternative to traditional template systems like ERB. It allows developers to write UI components entirely in Ruby, providing full control over structure, logic, and rendering without mixing HTML and templating syntax. One of its key advantages is performance, as it can render HTML extremely quickly while maintaining predictable scaling even with complex component hierarchies. Phlex integrates seamlessly with Ruby on Rails and supports common tools such as Tailwind CSS, Stimulus, and Turbo, making it easy to incorporate into modern Rails applications. It also emphasizes safety and maintainability by preventing common issues such as cross-site scripting through structural design and strict data handling. Developers benefit from reusable components, modular architecture, and the ability to stream content for improved performance and user experience. -

PhotoJShop
Photo editing JavaScript library
PhotoJShop is a JavaScript library for photo editing using the canvas and kernel convolution matrixes, aiming to reproduce the most usual filters. A demo of its capabilities can be seen in Nuophoto, a project that uses this library for all the editing. The idea is to provide a simple library to developers that will allow quick integration of photo filters to their website. After including jQuery, include photojshop.jquery.js. Once loaded you simply need to call it on a valid element. You have to ensure that the element has loaded, $(document).ready() doesn't mean images have loaded. -

Pinject
A pythonic dependency injection library
Pinject is a lightweight dependency-injection library for Python that favors explicit wiring and testability over magic. Instead of global singletons, you declare providers (bindings) that describe how to construct objects, and Pinject resolves the graph by inspecting call signatures. Its container supports constructor injection and fine-grained scoping so you can share expensive resources while keeping tests isolated. The library leans on Python’s introspection to minimize boilerplate, making it natural to adopt in codebases that already rely on type hints or keyword arguments. Because bindings are just Python functions and classes, refactoring remains straightforward and the DI graph is easy to reason about. Pinject is particularly useful for medium-to-large services where configuration, logging, data clients, and business logic need clean separation without resorting to manual plumbing. -

Pipeline Model Definition Plugin
Dfine CI/CD workflows using Jenkinsfile

Play-With-Sort-OC
Repository implemented in Objective-C with sorting algorithms
Play-With-Sort-OC is a learning-oriented repository implemented in Objective-C that demonstrates several classic sorting algorithms with code examples (selection sort, bubble sort, insertion sort, quick sort variants, heap sort, etc). The goal is educational; by showing how each algorithm works with animations or clear visualizations in an iOS/Objective-C context, the author helps developers understand not just the “how” but also the “why” behind each algorithm. The repo is especially suited for developers working in the Apple ecosystem (Objective-C, Xcode) who want to build foundational knowledge in data structures and algorithms. By making the code accessible, it lowers the barrier to exploring algorithm performance, variant comparisons, and understanding underlying complexity. For learners, it offers a bridge between abstract algorithm descriptions in textbooks and real code you can compile, run, tweak, and visualize. -

Playground Cheatsheet for Python
Playground and cheatsheet for learning Python
learn-python is another repository by Oleksii Trekhleb that serves as both a playground and an interactive cheatsheet for learning Python. It contains numerous Python scripts organized by topic (lists, dictionaries, loops, functions, classes, modules, etc.), each with code examples, explanations, test assertions, and links to further readings. The design supports “learn by doing”: you can modify the code, run the tests, see how behavior changes, and thus internalize Python language features, idioms, and good style practices (including linting and PEP8). Because it is organized in bite-sized chunks, it’s ideal for beginners or people refreshing their Python skills who want to revisit syntax and common patterns before moving into larger frameworks or applications. It also supports usage as a reference: if you forgot how a list comprehension works or how decorators behave, you can quickly open the relevant script. -

PleaseWait.js
JavaScript library to display customizable splash/loading screens
PleaseWait.js is a minimalist JavaScript library for showing splash-loading screens during the initialization of single-page applications (SPAs). It allows developers to define background colors, logos, and HTML content (like spinners) while delaying the main UI presentation. Once content is ready, it removes the loader and reveals the app. Installable via npm, Bower, or CDN. -

Plog
Portable, simple and extensible C++ logging library

Plumbing
Prismatic's Clojure(Script) utility belt
Plumbing is a general-purpose Clojure utility belt and data transformation library endorsed for its pragmatic approach to everyday tasks. It offers a toolkit of macros and functions that simplify common data manipulation patterns, and includes a “Graph” abstraction for structured computation flows. Most of it is also compatible with ClojureScript. Graph is a simple and declarative way to specify a structured computation, which is easy to analyze, change, compose, and monitor. Here's a simple example of an ordinary function definition, and its Graph equivalent. A Graph encodes the structure of a computation, but not how it happens, allowing for many execution strategies. For example, we can compile a Graph lazily so that step values are computed as needed. Or, we can parallel-compile the Graph so that independent step functions are run in separate threads. -
23
PocketSVG
Easily convert your SVG files into CGPaths, CAShapeLayers, etc.
A simple toolkit for displaying and manipulating SVGs on iOS and macOS in a performant manner. The goal of this project is not to be a fully compliant SVG parser/renderer. But rather to use SVG as a format for serializing CG/UIPaths, meaning it only supports SVG features that can be represented by CG/UIPaths. Thoroughly documented. -

Polysemy
Higher-order, no-boilerplate monads
Polysemy is a high-performance, zero-boilerplate effect system for Haskell, designed to simplify the handling of side effects in functional programs. Unlike traditional monad transformer stacks, Polysemy uses a modern approach based on freer monads and interpreters, allowing developers to define, compose, and interpret effects in a more modular and testable way. It aims to offer both flexibility and performance without sacrificing type safety or expressiveness.
