It converts Markdown into HTML5, roff formats, LaTeX, Gemini text, OpenDocument, and ANSI/UTF-8 terminal output, and it also exposes a C library API. ### プロジェクトの歴史 The official GitHub README states that lowdown is a fork of hoedown, but that its parser and front ends have changed significantly. The official project site describes it as a BSD.lv text-processing project and points to the GitHub repository for development, while directing stable releases, documentation, and general information to kristaps.bsd.lv. A key design point in the official site is that lowdown internally converts Markdown to an AST rather than directly formatting output. That architecture supports semantic analysis such as the `lowdown-diff` Markdown tree differ, and it helps explain why the project grew beyond a simple one-format Markdown renderer. ### 採用の歴史 The official site advises users to check their system package manager before building from source, and the batch input records packaging across Homebrew, Alpine, Debian/Ubuntu development packages, Fedora, MacPorts, Nix, Arch, and openSUSE. That broad packaging fits lowdown's profile as a small C tool and library useful in Unix documentation pipelines. The repository was created on GitHub in 2016. The project site reports version 3.0.1 and says lowdown has no dependencies, with portability across OpenBSD, NetBSD, FreeBSD, Mac OS X, Linux with glibc and musl, Solaris, and Illumos through `oconfigure`. ### 使われ方 As a CLI, `lowdown` can render Markdown to terminal output for quick review, standalone HTML5, roff `ms` or `man` output for PDF/manpage workflows, LaTeX, OpenDocument, Gemini text, and more. The site gives examples such as `lowdown -t term README.md | less -R`, `lowdown -s -o README.html README.md`, and roff/LaTeX pipelines for PDF generation. As a library, `lowdown(3)` exposes the parser and renderers used internally by `lowdown(1)` and `lowdown-diff(1)`. The language manual `lowdown(5)` documents Markdown features and extensions including autolinks, fenced code, tables, footnotes, smart typography, metadata, definition lists, task lists, admonitions, and templating. ### パッケージ好きにとっての重要性 lowdown is significant to package people because it is a compact, portable Markdown engine in C with no runtime dependency chain and many output back ends. It sits naturally beside `mandoc`, `groff`, and static-site/documentation tools, and its library packages make it useful both as a CLI and as an embeddable renderer. ### タイムライン - 2016: `kristapsdz/lowdown` repository created on GitHub. - 2020s: Version 2.0.0 adopts semantic versioning according to the official site. - 2026: Official site reports version 3.0.1 and repository metadata shows active maintenance. ### Related projects - hoedown is the fork source named by lowdown's README. - mandoc, groff, LaTeX, Gemini, and OpenDocument are important output or workflow neighbors named in the official docs. - oconfigure is the portability/build framework linked from the official site. ### ソース -
