Its package-manager niche is old-school TeX automation: a portable C command that can be dropped into documentation pipelines when compact HTML output is preferable to image-heavy conversions. ### Project history The official site presents TtH as a translator from TeX, especially mathematical TeX, into browser-readable HTML. The site's own pages are generated by TtH, and the homepage notes that the manual can be translated in real time from TeX source. Hutchinson's web-math overview records an original version in November 1997, with updates in 1998 and 2002, placing TtH in the first wave of tools trying to make scientific and mathematical documents practical on the web before browser-native math support was common. The distribution page describes TtH as portable to essentially any operating system, available as executables or C source, and still developing. The change log records version 4.00 on 5 December 2010, version 4.01 as the GPL2 public-source release, and version 4.16 on 25 July 2022. ### Adoption history TtH's adoption came from a specific web-publishing problem: TeX was strong for mathematical authoring, while early HTML lacked reliable math rendering. The official comparison page argues for native HTML using symbol fonts and tables as a fast, convenient alternative to PDF pages or image-based equations. The supplied package facts show TtH distributed through Homebrew, Debian, Fedora, MacPorts, and Ubuntu, evidence that it survived as a compact Unix-style converter even as newer TeX-to-web systems appeared. ### How it is used The official manual describes TtH as translating Plain TeX and LaTeX documents into HTML, including document structure, hyperlinks, equations, tables, bibliographies, indexes, graphics inclusion, and split output. The site emphasizes that TtH translates equations rather than rendering them as images, producing compact and fast-viewing web documents. The official examples include large lecture notes, a Plain TeX test document, and the TtH manual itself served from TeX source. ### Why package nerds care For package maintainers, TtH is valuable because it is a small, portable command-line converter with a long release history and very few moving parts compared with browser-driven or image-generation workflows. It is also historically interesting because the project pages are themselves artifacts of the tool: generated HTML pages that document the same TeX-to-HTML problem the package solves. ### Timeline - 1997: Hutchinson's web-math overview lists the original version of the discussion around TtH's approach. - 2006: The distribution page was generated by TtHgold 3.77 and described ongoing development and C-source distribution. - 2010: Version 4.00 released. - 2010: Version 4.01 released as the full public GPL2 source version. - 2022: Version 4.16 released. ### Related projects - TtM is the companion TeX-to-MathML translator linked from the official TtH homepage. - The official web-math comparison discusses LaTeX2HTML and TeX4ht as neighboring TeX-to-web converters. - TtHfunc is the function-callable version for integrating the translator into other executables. ### Sources - - - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. -
