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:
| attribute | description | valid values | default value |
|---|---|---|---|
| mathematical-format | format of generated images | svg, png | png |
| mathematical-ppi | ppi of generated images, only valid for png files | any positive number | 300.0 |
| mathematical-inline | if present will inline equations as svg (only useful for HTML output) | true/false | false |
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 ttf-lyx package in debian/ubuntu.
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 \

If you experience any compilation errors (caused by Mathematical) try running:
brew link gettext --force (you can unlink the libraries later if you want).
sudo apt-get -qq -y install bison flex libffi-dev libxml2-dev libgdk-pixbuf2.0-dev libcairo2-dev libpango1.0-dev ttf-lyx
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
