プロジェクトの歴史

The changelog traces the project back to `src2css` 0.1 in April 2002, followed by `highlight` 0.1 in July 2002 and `highlight` 1.0 in August 2002. Early releases added batch conversion, XHTML, RTF, TeX/LaTeX output, and more language definitions.

The 2.x line expanded output formats, language coverage, shared-library targets, filetype mapping, compatibility options for GNU source-highlight, and a rewritten Qt GUI. In 2009, the changelog records a license move from GPLv2 to GPLv3.

The 3.0 beta in June 2010 was a structural change: language definitions, themes, and filetype configuration were converted to Lua scripts, and a plug-in option was added. The 4.x line continued the Lua-script model while adding service-mode, LSP-related improvements, more languages, CMake/Meson work, and C++17 refactoring.

採用の歴史

highlight spread through Unix package managers because it is useful in documentation pipelines, static-site generation, editor/tool integrations, and terminal workflows. The input package map lists Alpine, Homebrew, Chocolatey, Debian/Ubuntu, Fedora, MacPorts, Nix, Arch, Scoop, and openSUSE-style packages.

Official extras also show integration beyond one-off CLI use. The Pandoc example demonstrates using highlight as an external highlighter inside document preprocessing, including importing external source files and inline themes.

使われ方

Common use is `highlight -i main.cpp -o main.cpp.html` for HTML, `highlight < main.cpp > main.cpp.html --syntax cpp` for standard-input workflows, or `highlight -O latex` for TeX/LaTeX output. Batch and recursive options let it process trees of source files.

Users customize behavior through language definitions, themes, plug-ins, file mappings, and output-format flags. The manual documents terminal truecolor and xterm256 output as well as document formats, making the tool relevant both on the command line and in generated artifacts.

パッケージ好きにとっての重要性

highlight is package-nerd material because it is old-school Unix plumbing that still tracks new languages and output targets. It can sit behind manpage/documentation generation, static websites, code samples, and terminal previews without forcing a runtime-heavy web stack.

Its Lua-definition architecture is also useful for downstreams: language and theme behavior can be patched or extended as data files, which fits distribution packaging better than editing core parser code for every syntax tweak.
