Is there a way to automatically generate a colophon information in LuaTex?

Ideally I would like to automatically generate a file (plain text) that will list the different font and font-families that actually appear in the tex (LuaTex) document incase latex substitutes missing fonts or if a particular fonts family isn't declared.

Thank you!

    That information is generated in the .log already. Do you mean you want this for diagnostic purposes or that you want to generate a colophon in the actual output?

  • Thank you. My primary goal is for diagnostic purposes. I tried 'grep font ' on the log and it wasn't as informative as I would like. I would prefer a more cleaner output -with the option for output- if it can be done easily.

    Well, you can do pdffonts myfile.pdf to get a the font info. But the .log tells you about the substitutions that were made so you can fix the problems (if any).

You can put pdffonts in a script so that after you compile the document it automatically generates the text file you want, texfonts.sh:

set -e


latexmk -pdf -lualatex "$INFILE"
pdffonts "${INFILE%.tex}.pdf" > "${INFILE%.tex}-fonts.txt"

Here's a sample file to demonstrate, test.tex:


\setmainfont{TeX Gyre Pagella}
\setsansfont{TeX Gyre Heros}
\setmonofont{TeX Gyre Cursor}
\newfontfamily{\greekfont}{EB Garamond}






    Greek & {\greekfont λόγος} \\
    Mandarin & {\chinesefont 我们爱狗。} \\




Run sh texfonts.sh test, and there will be two outputs: the text file test-fonts.txt and the PDF.

  • Is that cross-platform, without needing to install other software?

  • If you install TeXLive from tug.org you'll have latexmk. For the script you need a Unix-like shell and the pdffonts program. Most Linux systems will have both already installed. Mac OSX provides a shell (Terminal app) but you have to install pdffonts separately: stackoverflow.com/questions/32420994/…. I don't know about Windows. Apr 9 '18 at 13:21
