Image processing relies on the binary program convert, from
imagemagick. The built program that generates the static website
assumes that the binary convert is available somewhere in user’s
path; it will crash without warning if it is not the case!
This builds a static website. All the website files are pushed in the
subdirectory _site.
make
To force a full rebuild:
$ make rebuild
The build rule watch loads the built static website in a local web
server, and automatically rebuilds the target files when changes are
detected in the source files.
$ make watch
The subdirectory site is a git submodule. Its contents are synced
from the contents of subdirectory _site. The purpose of the site
submodule is to be pushed on remote repository services such as github
pages, for hosting static websites.
