Material developed for the AST400A course (one semester) at the Department of
Astronomy and Steward Observatory of the University of Arizona (Fall
semester 2024/Spring semester 2025).
The lecture notes are written as emacs org files available in
./org-content and exported to html (available online here, the output
of the export also relies on the css and html templates in
./html-content), and in pdf (compiled with LaTeX) for printing and
annotating before I give a lecture.
The script build.sh is the main script to build the website. It first
checks if the flag all was passed as an argument, in which case it
will build all the org files, otherwise it will look for the org-files
that have been modified using git diff and only build those.
The script actually calls emacs to do the build (with -Q flag so the
process does not depend on my specific emacs configuration), which is
run by build.sh in script mode to run the elisp script build-site.el.
build-site.el checks for the htmlize and ox-publish packages, and
installs them locally if they are not available, then exports to html
the appropriate files (either all the org files or the ones modified
since the last commit) to the folder html-content, and hands back the
control to build.sh, which finishes things by pushing to this repo and
rsync the html files from the server where I host the website (this is
just because the server is very old and I cannot have a modern version
of emacs to build directly there).
Each semester’s website is archived as a release. The Fall 2024 semester corresponds to release v1.0.
