Markdoc is a documentation content framework that extends standard Markdown with custom tags, typed schemas, and reusable components, parsing content into an abstract syntax tree and rendering it as React elements or HTML. It provides a structured authoring system where documents are processed through an AST-based pipeline, enabling validation, transformation, and flexible output generation. The framework distinguishes itself through a schema-driven validation pipeline that checks document structure and attribute values against defined rules, and a pluggable renderer architecture that accepts

This is a reference guide for GitHub Flavored Markdown syntax, focused on formatting README files and other repository documentation. It covers the full range of Markdown elements supported on GitHub, including tables with column alignment, images, hyperlinks, emoji shortcodes, inline code, and badges from external services. The guide explains how to create structured content such as alert blocks with NOTE, TIP, WARNING, and CAUTION labels, as well as diff blocks that highlight added and removed lines. It also covers centering content on the page and using reference-style links for reusable l

QOwnNotes is a desktop note editor that stores each note as a plain-text Markdown file on the local filesystem, avoiding proprietary formats and enabling direct file access. It functions as a Nextcloud Notes client, syncing notes and metadata with Nextcloud or ownCloud servers through a companion API service for versioning and sharing. The application also integrates with AI providers and exposes a local MCP server for external agents to search and fetch notes, and includes a companion browser extension for capturing web content, bookmarks, and screenshots. The editor distinguishes itself thr

Codehike est un framework de documentation basé sur React et un outil de walkthrough de code interactif. Il fonctionne comme un orchestrateur de contenu markdown qui transforme le markdown décoré en données structurées et en composants React, servant de couche de visualisation pour mettre en évidence des plages de code, des diffs et des erreurs de compilation. Le projet se distingue par sa capacité à créer des expériences de "scrollycoding" et des tutoriels techniques étape par étape. Il propose des animations au niveau des tokens qui démontrent visuellement l'évolution de la logique entre les versions de code et fournit un système pour synchroniser l'état de l'UI avec la position de défilement du navigateur. Le framework couvre un large éventail de capacités de visualisation, incluant la création de diaporamas de code, des mises en page en surbrillance et des blocs de code à onglets. Il supporte l'annotation détaillée via des tooltips, des callouts et des notes de bas de page, ainsi que des utilitaires fonctionnels comme des sélecteurs de langage, la transpilation de code et l'intégration de données de compilation en temps réel. Le système utilise une validation basée sur des schémas pour garantir la sécurité des types et la cohérence des données extraites des fichiers markdown.

This project is a markdown syntax cheatsheet and reference guide designed for writing documents with a focus on GitHub Flavored Markdown. It serves as a formatting reference and documentation template for creating technical content and project landing pages. The guide provides a comprehensive collection of examples for GitHub specific extensions, including task lists and callout alerts. It functions as a visual directory for implementing structured layout elements such as tables, mathematical equations, and code blocks. The reference covers broad capability areas including content and media

react-syntax-highlighter is a React component that renders source code with language-specific syntax coloring. It wraps the Prism and Highlight.js syntax highlighting libraries, tokenizing source code using their language grammars and mapping each token to a styled React element. The component operates in two styling modes: inline style objects applied directly to each token, or CSS class names that can be themed via external stylesheets. This dual-mode approach makes the highlighter portable across environments where CSS class injection may or may not be available. The component is built aro

Streamdown is a streaming markdown renderer for React that transforms incoming markdown text into sanitized HTML in real time, handling incomplete blocks as they arrive. It parses GitHub-Flavored Markdown syntax including tables, task lists, and footnotes, and renders LaTeX math expressions using KaTeX, Mermaid diagrams as interactive SVGs, and code blocks with Shiki-based syntax highlighting supporting over 200 languages with dual light and dark themes. The renderer includes an XSS-safe HTML sanitizer that strips dangerous tags and validates URLs to prevent injection attacks. What distinguis

Python-Markdown is a library that converts Markdown text into HTML or XHTML documents. It functions as a Unicode text processor, supporting all Unicode-based languages and bi-directional text to ensure global compatibility. The project is an extensible markdown processor that allows developers to add custom syntax and formatting rules through a plugin architecture. This system enables the registration of new parsing rules, the modification of parser behavior, and the implementation of custom document syntax such as tables and footnotes without altering the core source code. The tool provides

This project is a Python library and command-line tool designed to convert Markdown text and files into structured HTML fragments. It functions as a Markdown-to-HTML converter and parser that transforms piped text or source files into web-ready documents. The project is an extensible text processor featuring a pluggable API for defining custom inline and block syntax. This modular framework allows for the registration of specialized syntax extensions, such as tables and footnotes, and provides a system for managing runtime configuration settings. The conversion process covers multilingual te
