history
Project history and usage
gemgen is a small command-line converter from CommonMark Markdown to Gemtext, the lightweight markup used by Gemini protocol capsules. Its history is best understood as part of the early-2020s tooling wave around maintaining text-first Gemini sites from more common Markdown source material.
Project history
The SourceHut repository began in August 2021 and reached tagged releases through v0.6.0 by February 2022. The README describes a Go tool built on goldmark and a companion goldmark-gemtext renderer, with options for preserving or adapting Markdown constructs to produce readable Gemtext rather than a purely mechanical dump.
The project scope stayed deliberately narrow: it converts files concurrently or streams Markdown from standard input to Gemtext on standard output, with extra support for link rewriting, templates, wiki-style links, and formatting choices useful when publishing static Gemini content.
Adoption history
gemgen's adoption evidence is modest and niche. The upstream README lists Arch AUR and Homebrew packaging, and Go package metadata identifies it as a command module rather than a widely imported library.
How it is used
Practitioners use gemgen to keep Markdown as the editable source for Gemini capsules, then generate `.gmi` output during publishing. The tool pays special attention to Gemtext conventions: links are placed after paragraphs, headings and lists are simplified, emphasis can be removed or retained, and code blocks are emitted in fenced Gemtext form.
Why package nerds care
For package maintainers, gemgen is a compact example of Gemini-era publishing tooling: a single-purpose CLI, small Go dependency tree, manpage-oriented installation, and enough release discipline to appear in Homebrew despite its narrow audience.
Timeline
