Just knocked up (really mostly borrowed) a quick solution to mirror my gemlog to my https site.
Several people seem to go from some other source to both '.gmi' and '.html', or run a proxy. As my web site is on a slow machine a conversion is better, but I want '.gmi' to be the primary format. Sounded like a job for an awk script, and a bash script, so I searched and found:
https://gist.github.com/dracometallium/bf70ae09b4dd9a857d33e93daa2810c4
Thanks to dracometallium for posting that. I adapted it a bit, and then wrote a simple bash wrapper script. The wrapper script copies everything from my 'gemlog' directory of my capsule to the 'blog' directory of my site and does the conversions:
#!/usr/bin/env bash
set -u
SOURCE="."
TARGET="/home/dave/html/blog"
echo "Gemlog to Weblog conversion"
echo
echo "With thanks to dracometallium on GitHub for their AWK script!"
echo
echo "Removing old target dir: ${TARGET}"
rm -rf "${TARGET}"
echo "Creating new target dir: ${TARGET}"
mkdir -p "${TARGET}"
cp -a ${SOURCE}/* "${TARGET}"
for g in $(find "${TARGET}" -name '*.gmi'); do
h="${g%.gmi}.html"
echo "Converting ${g} to HTML"
gawk -f ./convert.awk "${g}" > "${h}"
rm "${g}"
done
echo
echo "Done"
echo
The awk script that I borrowed, and adapted is also below for posterity:
#!/usr/bin/gawk -f
