Hi, my name is Libor JelĂ­nek. I'm just a programmer do love documentation. I was born and live in the Czech Republic. I'm datetime.date.today().year - 1984 years old.

In past, I spent 10 years in Java, the last 5 years doing Python and JavaScript. My main job now is tech writing, but I still actively contribute to a number of open-source projects.

During my career, I led many computer training, wrote a few books, and translated others from English to Czech.

I founded Documatt, an online tool for authoring docs, manuals and books for tech and novel writers.

Sphinx doc extensions.

I wrote few extensions for Sphinx documentation.

  • sphinxcontrib-constdata (documatt.gitlab.io/sphinxcontrib-constdata/). Allows showing values, listing tables, and generating links from CSV, JSON and YAML files. Python
  • sphinx-reredirects (documatt.com/sphinx-reredirects). Handles redirects for moved pages. It generates HTML pages with meta refresh redirects to the new page location to prevent 404 errors if you rename or move your documents. Python

Misc smaller projects.

Small or in-progress side projects.

  • Page Counter (github.com/liborjelinek/page-counter). Python library and commandline tool to count number of standard pages in the text, files and folders. Python
