Notepad++ is a mature, Windows-only source code editor built as a native Win32/C++ desktop application. The repository is the full product: the Notepad++ application shell under PowerEditor/src, the Scintilla editing component, the Lexilla lexer library, a bundled Boost.Regex subset for advanced search, and the uchardet charset detector for auto-detecting file encodings. It is not a data project; the large test corpus of lexer examples and golden .styled/.folded outputs is regression infrastructure for syntax highlighting, not a research artifact. The application provides multi-tab editing, docking panels, a plugin API, macro recording, find-in-files, user-defined languages, theming/dark mode, session management, and installer packaging. Entry points include winmain.cpp, Notepad_plus_Window.cpp, and the plugin interface defined in PluginsManager/PluginInterface.h.
fylepad is a note-taking application built with Vue 3 and Tauri that provides a rich text editing experience with AI integration. It functions as both a web application and cross-platform desktop app, offering features like markdown editing, diagram support (Mermaid, PlantUML), media embeddings (YouTube, Spotify), and AI-powered text assistance. The application uses a local-first approach with IndexedDB/SQLite storage and optional cloud synchronization. The architecture follows a component-based pattern with Vue.js, utilizing Tiptap for the core editor functionality and numerous extensions for specialized features. State management is handled through Vue composables, and the UI is built with @nuxt/ui components. The application includes sophisticated features like offline support, conflict resolution, and a responsive interface that adapts between web and desktop contexts.
TiddlyWiki5 is a mature, extensible personal wiki application that runs entirely as a single HTML file in the browser or as a Node.js server. It manages content as individual 'tiddlers' — small, addressable pieces of text with metadata — and provides a powerful custom filter language for querying, transforming, and aggregating them. The application features a widget-based UI rendering engine, a pluggable wiki-text parser with dozens of rules, a built-in HTTP server with REST-like endpoints, encryption, and extensive integration plugins (geospatial maps via Leaflet/Turf, math typesetting via KaTeX, Markdown parsing, CodeMirror editing, QR codes, etc.). The architecture is highly modular: core functionality is implemented via module types (widgets, filter operators, parser rules, startup hooks, saver backends) that can be extended or overridden by plugins. The codebase has been continuously developed since 2011 and supports both client-side single-page application mode and server-side wiki mode. Despite its impressive extensibility and long history, the codebase shows signs of technical drift. The boot kernel (boot/boot.js) is a large monolithic file that mixes utility functions, the wiki store, module loading, and platform-specific startup logic. Many third-party libraries (e.g., JSZip v2.6.1, Leaflet.markercluster 1.5.3, minified CodeMirror modes) are vendored and outdated, requiring manual patching. The code style is inconsistent, with some modules using modern ES6+ features while others remain in ES5. The filter language and widget infrastructure are well-architected and reusable, but the tight coupling between core modules makes extraction for external use non-trivial. The project remains actively maintained with frequent commits, a large community, and an extensive test suite, making it a solid foundation for knowledge management applications, though significant refactoring would be needed to bring it to contemporary best practices.
This repository provides the 'Dark+ Modern' theme for Notepad++, a complete visual overhaul that replicates the color palette of VS Code's Dark+ and Dark Modern themes. The core deliverable is a single large XML file (`Dark+ Modern.xml`) that defines syntax highlighting styles for over 90 programming languages, along with global editor widget styles (caret, selection, line numbers, folds, etc.). Accompanying files include a Markdown User Defined Language (UDL) definition (`plugins/markdown-dark.xml`), a CSVLint plugin configuration (`plugins/CSVLint.xml`), an automated install script (`install.cmd`), and a comprehensive set of screenshots with sample source files. The theme is not a software application but a configuration artifact; its architecture is a flat XML schema with no code logic, tests, or build system. It is well-documented, actively maintained, and directly installable into Notepad++.
