It exists to make Markdown behavior testable, portable, fast, and consistent across implementations. ### Project history CommonMark grew out of the need for an unambiguous Markdown specification after years of divergent Markdown implementations. The CommonMark site says the effort started in 2014 with implementers and large-scale Markdown users, and the cmark README credits John MacFarlane with the original library and program alongside contributors to parsing, optimization, links, emphasis, APIs, and tests. ### Adoption history The CommonMark site reports implementations for dozens of programming languages and lists adopters including Discourse, GitHub, GitLab, Reddit, Qt, Stack Overflow/Stack Exchange, and Swift. The batch input lists cmark packages across Homebrew, Alpine, Debian, Fedora, MacPorts, Nix, Arch, Ubuntu, and openSUSE/zypper. ### How it is used The cmark program parses CommonMark documents and renders HTML, groff man, LaTeX, CommonMark, or XML AST output. The library exposes an AST for programmatic manipulation and is wrapped by bindings for multiple languages; the README also documents security behavior around raw HTML and unsafe links. ### Why package nerds care cmark is important because it gives package ecosystems a small, fast, C99, dependency-light implementation of a standardized Markdown dialect. It is a common build or test dependency for projects that want Markdown rendering without inheriting each host language's quirks. ### Timeline - 2004: Markdown is released by John Gruber with Aaron Swartz, providing the background problem CommonMark later addresses. - 2014: CommonMark publishes early spec versions, with 0.5 and 0.6 appearing in October. - 2015: the current commonmark/cmark GitHub repository is created. - 2024: CommonMark spec 0.31.2 is listed as the latest spec version on spec.commonmark.org. ### Related projects - cmark is related to the CommonMark spec, commonmark.js, cmark-gfm, Markdown.pl, Babelmark, and language bindings for Go, Haskell, Ruby, Lua, Perl, Python, R, Scala, and PHP listed in the README. ### Sources -
