asciidoctor-mathematical

Alternative stem processor for asciidoctor based on Mathematical.

asciidoctor-mathematical processes latexmath and stem blocks and inline macros and replaces them with generated SVG or PNG images, thus enables stem contents on a much wider range of asciidoctor backends. Currently, it is tested to works well with the html, docbook, pdf and latex backends. For stem blocks and macros, only the latexmath type is supported.

These attributes can be set to tweak behaviors of this package:

asciidoctor-pdf -r asciidoctor-mathematical -o test.pdf sample.adoc

asciidoctor-mathematical is now available on RubyGems. Installation is done by gem install asciidoctor-mathematical. Install dependencies first.

make, gobject, glib, gio, gdk-pixbuf, gdk, cairo, pangocairo, libxml, bison, flex

For the runtime, the following ttf fonts should be installed: cmr10, cmmi10, cmex10 and cmsy10. They are provided by the lyx-fonts package in fedora, and the fonts-lyx (or previously ttf-lyx) package in debian/ubuntu. In Arch Linux you can install the ttf-computer-modern-fonts package from AUR, you also have the lyx package in extra repo though; both are providing required Computer Modern fonts.

Make sure you brew install glib gdk-pixbuf cairo pango cmake

You can install the font dependencies by using

cd ~/Library/Fonts
curl -LO http://mirrors.ctan.org/fonts/cm/ps-type1/bakoma/ttf/cmex10.ttf \
     -LO http://mirrors.ctan.org/fonts/cm/ps-type1/bakoma/ttf/cmmi10.ttf \

If you experience any compilation errors (caused by Mathematical) try running: brew link gettext --force (you can unlink the libraries later if you want).

The mathematical gem cannot currently be installed on Fedora 29.

The mathematical gem, which is a hard dependency of asciidoctor-mathematical, may fail to build because of its over-writing of strdup. Whether it fail depends on the system. In case it fails, use the following command to install mathematical (see gjtorikian/mathematical#64 for the details):

MATHEMATICAL_SKIP_STRDUP=1 gem install mathematical
