📚 Markdown Standardization and Evolution
History and Standardization of Markdown
Markdown was created by John Gruber in 2004 as a simple and readable text format. It was designed to avoid HTML's complex syntax, making it easy for anyone to write. Its versatility and ease of use have led to widespread adoption across blog platforms, development documentation, static site generators, and many other fields.
CommonMark Standard: Pursuing Consistency
Initially, Markdown lacked clearly defined specifications, leading to compatibility issues between different implementations. To address this, the CommonMark project was launched in 2014. CommonMark is a unified specification with the following features:
- Strict specification: Eliminates ambiguity and ensures consistency across different environments
- Comprehensive test suite: Over 650 test cases verify implementation accuracy
- Extensibility: Designed for easy custom extensions and new feature additions
Tools compliant with CommonMark guarantee identical conversion results, enhancing portability between projects.
GitHub Flavored Markdown (GFM): Pursuing Practicality
GitHub introduced GitHub Flavored Markdown (GFM), adding useful extensions to CommonMark for real-world development workflows. GFM is used throughout GitHub (README.md, Issue comments, etc.) and has become a de facto standard for developers.
- Tables: Pipe-delimited table format for data presentation. Very useful for documentation and API specifications.
- Strikethrough: Display completed checklist items or deprecated information with ~~text~~.
- Task Lists: Progress tracking with - [ ] or - [x]. Used for project management and issue tracking.
- Auto-linking URLs: URLs become links automatically without brackets or symbols. Perfect for casual communication.
- Language-specific code blocks: Specify language like ```javascript for syntax-highlighted HTML generation.
- Mentions & issue references: Auto-link @username or #issue-number. Significantly improves team communication efficiency.
This Markdown→HTML converter uses marked.js to comply with CommonMark standards while supporting GFM extensions (tables, strikethrough, task lists, etc.). This ensures you can safely use standard Markdown and GitHub syntax.
