2023-12-17 – The Responsive Package is Now on CTAN

I've released the Responsive package on CTAN. Provided features include font size adjusting for different page sizes, changes of line spacing, typographic scales and media queries.

My talk about the Responsive package is now available on Youtube.

2023-11-28 – New Tool on CTAN

I've released a new tool, TeXBlend. 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.

2022-11-17 – Automatic typesetting using LuaLaTeX

At the CSTUG general meeting, I gave a talk on responsive design and automated typesetting using LuaLaTeX. I demonstrated the use of the Responsive, Luavlna, Linebreaker, and Lua-widow-control packages. You can find a recording of the talk and slides on the CSTUG website or on Youtube. Unfortunately, they are only available in Czech, but I hope they can still be useful to someone.

Projects

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.

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
LuaXML – handle XML files with LuaTeX
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.
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?.
HTML parser for LuaXML – it works and will be included in the next LuaXML release.
Rmodepdf – typeset HTML files with LuaLaTeX. It can remove unnecessary content from web pages thanks to Rdrview (similarly to reader mode in Firefox).
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.
