Installation

pip install texmark

External dependencies

texmark itself is pure Python, but it shells out to a few external tools to produce the final PDF.

• pandoc — the markdown → tex engine. The easiest install is pip install pypandoc_binary, which ships the pandoc binary as a PyPI wheel (no system package manager, no sudo, same on Linux/macOS/Windows, recent pandoc 3.x). If you'd rather have a single shared install across venvs, use your system package manager instead (see below) — texmark picks up either.
• A LaTeX distribution providing pdflatex, bibtex, and latexmk (texmark's default driver) plus the standard package set (hyperref, natbib, amsmath, graphicx, geometry, microtype, booktabs, caption, mathptmx, newtxtext, newtxmath, apacite, draftwatermark, mdframed, tikz, xcolor, appendix, lineno, epstopdf, …). Optionally tectonic as a single-binary alternative (see Build backends).

On Debian / Ubuntu:

sudo apt install pandoc \
    texlive-latex-extra texlive-bibtex-extra \
    texlive-publishers texlive-fonts-extra

…or just texlive-full for the easy answer.

On macOS (Homebrew):

brew install pandoc
brew install --cask mactex     # or basictex + tlmgr install <packages>

A handful of LaTeX packages that aren't in TeX Live's smaller installs (notably trackchanges, algorithm / algorithmicx, jabbrv) are bundled with texmark under texmark/templates/<journal>/ and copied into the build directory automatically, so you don't need to install them separately.
