Its upstream material describes it as a powerful Markdown processor geared toward IETF documents, but also usable for books and technical documentation. The IETF authors' tools catalog lists mmark as a Markdown-to-RFCXML tool, credits Miek Gieben as author and maintainer, and classifies it as a maintained command-line/build tool. ### Project history The tool's main milestone is support for the RFC 7991 XML vocabulary used by xml2rfc v3. Mmark takes an extended Markdown dialect with title blocks, special sections, citations, XML references, BCP14 keyword handling, captions, figures, includes, indexes, and cross references, then emits RFCXML, HTML5, or manual-page output. The generated RFCXML is meant to be passed to xml2rfc for final text, HTML, PDF, or other RFC outputs. ### How it is used Mmark belongs to the small ecosystem of tools that let IETF authors write Internet-Drafts in lightweight text formats instead of raw XML. It sits near kramdown-rfc and metanorma-ietf, with a package-manager niche as a single CLI for authors who want local Markdown-to-RFCXML conversion in scripts, Makefiles, and continuous document builds. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** mmark - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Debian apt - golang-github-mmarkdown-mmark-dev - 2.2.25+dfsg1-2: normalized package name match | Debian stable package indexes: golang-github-mmarkdown-mmark-dev from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | powerful markdown processor in Go geared towards the IETF (library) | https://github.com/mmarkdown/mmark - Debian apt - mmark - 2.2.25+dfsg1-2: normalized package name match | Debian stable package indexes: mmark from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | powerful markdown processor in Go geared towards the IETF (program) | https://github.com/mmarkdown/mmark - Nix - mmark: normalized package name match | nixpkgs package indexes: pkgs/by-name/mm/mmark/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - golang-github-mmarkdown-mmark-dev - 2.2.25+dfsg1-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: golang-github-mmarkdown-mmark-dev from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | powerful markdown processor in Go geared towards the IETF (library) | https://github.com/mmarkdown/mmark - Ubuntu apt - mmark - 2.2.25+dfsg1-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: mmark from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | powerful markdown processor in Go geared towards the IETF (program) | https://github.com/mmarkdown/mmark - MacPorts - mmark: normalized package name match | MacPorts ports tree: textproc/mmark/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [github-markdown-toc](https://www.automicvault.com/pkg/brew/github-markdown-toc/) - Shares av.db curated category or tags: cli, developer-tools, documentation, markdown. - [grip](https://www.automicvault.com/pkg/brew/grip/) - Shares av.db curated category or tags: cli, developer-tools, documentation, markdown. - [mandown](https://www.automicvault.com/pkg/brew/mandown/) - Shares av.db curated category or tags: cli, developer-tools, documentation, markdown. - [gtree](https://www.automicvault.com/pkg/brew/gtree/) - Shares av.db curated category or tags: cli, developer-tools, documentation, go, markdown. - [xml2rfc](https://www.automicvault.com/pkg/brew/xml2rfc/) - Shares av.db curated category or tags: cli, developer-tools, documentation, ietf, rfc. - [action-docs](https://www.automicvault.com/pkg/brew/action-docs/) - Shares av.db curated category or tags: cli, developer-tools, documentation, markdown. - [cheat](https://www.automicvault.com/pkg/brew/cheat/) - Shares av.db curated category or tags: cli, developer-tools, documentation, go. - [cmark](https://www.automicvault.com/pkg/brew/cmark/) - Shares av.db curated category or tags: cli, developer-tools, documentation, markdown. ## Combined YAML source View the package source record on GitHub.
