TeX4ht

I am a developer of TeX4ht, a converter from LaTeX to HTML, OpenDocument Format, and other XML-based formats.

Supporting Packages

• make4ht – main conversion script for running TeX4ht. Documentation.
• tex4ebook – conversion script for creating Epub files.
• make4ht action – run make4ht in Github Actions.
• Mjcli – command line MathJax compiler. It can be used with the mjcli extension for make4ht.
• Siterebuild – tool to detect which LaTeX files needs to recompile. Useful in automated environments.

Documentation and Showcases

• Documentation / sources.
• Sample blog – this blog is published directly from LaTeX sources published to Github. See the sources for the setup.
• Conversion of Overleaf documents using Github Actions.
• PythonTeX Gallery compiled by TeX4ht.
• Tufte LaTeX to HTML using TeX4ht / Sources.

LuaXML

LuaXML is a XML and HTML parser for Lua. It consists of several libraries.

LuaXML Libraries

• The luaxml-domobject library provides an interface to parse, manipulate, and traverse XML and HTML documents as a Document Object Model (DOM) tree, allowing structured access to the XML elements and their attributes.
• The luaxml-transform library applies XSLT-like transformations to the DOM object, enabling conversion of XML data into different formats or structures based on specified templates.

LaTeX Packages

My LaTeX packages that are not related to LaTeX to HTML conversion:

• BibLaTeX ISO 690 – ISO 690 style for BibLaTeX
• Ctanbib – extract BibTeX information from CTAN entries of LaTeX packages
• Linebreaker – prevent overfull boxes with LuaTeX
• Lua-UCA – Unicode collation algorithm for LuaTeX
• Luavlna – prevent line breaks after single-letter words, units, or academic titles
• ODSFile – Read OpenDocument Spreadsheet documents as LaTeX tables
• Responsive – idea is to allow design of page layout and font sizes in LaTeX document depending on the paper size, similar to responsive design in CSS.
• Rmodepdf – typeset HTML files with LuaLaTeX. It can remove unnecessary content from web pages thanks to Rdrview (similarly to reader mode in Firefox).
• Sectionbreak – insert asterism or other characters as dividers between sections
• TeXbBlend – this tool compiles individual files that are included as parts of larger documents. It utilizes the preamble of the main document but disregards all other included files.
• Uninormalize – Unicode normalization for LuaTeX

Vim

• Vim-zettel – Zettelkasten plugin, based on Vimwiki
• Vimwiki sync – synchronize Vimwiki and Git

Unfinished Projects and Work in Progress

I have a habit to start lot of projects in my hyper-focus seasons. Unfortunately, I often left then unfinished, or mostly finished, but without documentation. Here is a list of these, that are most interesting for me.

• Rdfref – referencing system for LaTeX, inspired by RDF. It has a query language inspired by Sparql. Documentation is missing, some info is only in my answers on TeX.se: Analysis of cross-reference/link network within a single document, Define a command (like table of contents) but for attendees, Show graph of references inside a document and Is there a software in Ubuntu that can analyse the cross references (theorems, lemmas, equations, etc.) in a tex project?.
• Linemarkup – LuaLaTeX package for support of line oriented markup languages (such as Gemini or Subtext.
• Luaepubreader – Epub reader for LuaLaTeX. It should enable for direct typesetting of Epub files. It is in an early stage of development, it can read list of files in the Epub files, but nothing more. It depends on the finishing of the HTML parser.
• Cooklang-lua – Lua parser for the Cooklang. Parser works, but it needs a LaTeX interface.
• Luaspreadsheet – Lua module for reading of spreadsheet files. Currently, it supports only reading of XSLT files.
• Lualiterate – support for API comments in LaTeX packages. In a proof-of-concept state.
• TeXparser – Lua parser for LaTeX. Idea was to strip LaTeX commands, create a text file useful for grammar checking or other tools that don't support LaTeX syntax, and then apply changes in that text file back to LaTeX sources.

Other Projects

I have more FOSS projects on my GitHub page.

About

I am Michal, a librarian and FOSS developer from Prague, Czechia. I have wanted to create a proper homepage for a long time, but I always had overly ambitious plans, and I ended up procrastinating on other projects instead. As it became evident that I was not going to accomplish all of my plans, I decided to create a minimal page and start from there. I will gradually add more information and, hopefully, also some articles in the future.

What is Kodymirus

Kodymirus was an arthropod that lived in the Lower Cambrian period in the area of today's Brdy Hills in central Bohemia. It is one of the oldest fossils that can be found in the Czech Republic. Why did I choose this name for this site? It doesn't have any deep meaning. I just like the Brdy Hills and paleontology and found this name amusing. That's all.
