Moving talks.jvt.me to reveal-hugo

As part of the Merge Request Convert Reveal.JS slides to reveal-hugo, talks.jvt.me is now built using Josh Dzielak's project reveal-hugo.

This makes the setup of the project much more simple, and means I now have a well tried-and-tested structure for creating Reveal.JS presentations.

As mentioned in the merge request description:

Instead of using a homegrown, overly engineered setup for my slides, it's easier to re-use existing setup such as reveal-hugo, especially as I now use Hugo for jvt.me.

My original setup was creating revealjs-starter which used Ruby's ERubis templating language with a custom YAML config file and a Rakefile to tie together the build process, which was then served with Rackup. Most of these would be symlinks from the starter project so there wouldn't need to be as much duplication, but it wasn't really the best practice for a lot of repetition.

This was partly as Ruby is my new favorite scripting language, but also as I didn't want to use something like generator-reveal as it was a bit Node-heavy and I wasn't a fan.

When I got used to my horrible Ruby setup, it was pretty straightforward to work with, but after months of not touching a presentation it was not as fun coming back to the repo, as I would have to re-learn how it all works.

As part of the move to reveal-hugo, it also meant that I needed to script the conversion of the existing setup to reveal-hugo's expected setup. And this migration needing quite a lot of scripting also showed just how bad the original setup was.

This also means I have the blazing fast speed of Hugo, as well as making it much easier to manage GitLab CI setup:

Which wasn't very scalable, as each new presentation requires a build step and a deploy step.

Where I previously had these two files to orchestrate the build steps .ci/build-reveal-site.sh:

#!/usr/bin/env sh

cd "$1"
# Install front-end dependencies
npm install
./node_modules/bower/bin/bower --allow-root install
# install rake+erubis
bundle install --path vendor/bundle
bundle exec rake

Which is then "deployed" by .ci/deploy-reveal-site.sh into the right folder, and adding a link to the index.html:

#!/usr/bin/env sh

# `-L` to resolve symlinks and output the files as they are
cp -LR "$1/out" "public/$1"
mv "public/$1/slides.html" "public/$1/index.html"
echo "<a href='$1/'>$2</a>" >> public/index.html

reveal-hugo also has an easier ability to customize the setup for Reveal.JS itself on a per-presentation basis which is much easier than the existing setup I had which wasn't as flexible.

I'm really enjoying the developer experience of reveal-hugo in comparison to my existing setup!
