with the following added languages in anticipation of document expansion:
apache dockerfile dos less php powershell python tex yaml
To reproduce docs/static/js/highlight.pack.js on Debian/Ubuntu:
$ sudo apt-get install nodejs npm
$ wget https://github.com/isagalaev/highlight.js/archive/9.0.0.tar.gz
$ tar xzf 9.0.0.tar.gz
$ cd highlight.js-9.0.0/
$ npm install
$ nodejs tools/build.js markdown asciidoc xml css javascript \
ini yaml json go bash diff dockerfile dos powershell makefile \
apache nginx tex http php python ruby django haml handlebars \
scss less coffeescript
Then, copy the resulting build/highlight.pack.js as well as
src/styles/monokai-sublime.css to the appropriate Hugo docs directories.
The GitHub:buttons JavaScript code docs/static/js/buttons.js
from https://github.com/ntkme/github-buttons was referenced
in docs/layouts/partials/footer.html but never used.
Apparently, the actual code for the GitHub buttons on the upper-left
corner of gohugo.io documentation was written by @spf13 in
docs/static/js/scripts.js.
