To develop new features, it's nice to work on a local devserver. This project uses jekyll to generate the static webpages and npm/TS/rollup to bundle the Javascript. If you just want to work on the HTML/CSS/jekyll part of the project, you just need to install jekyll. If you want to also work on the scripts, you will also need to install npm and the dependencies.

Follow https://en.terminalroot.com.br/how-to-properly-install-ruby-bundler-and-jekyll-on-ubuntu-linux/ to install ruby and jekyll. You will need ruby 2.x.x for jekyll to work with github pages. That's why I recommend installing ruby through rvm (the ruby version manager) to easily switch between ruby versions.

Once you have ruby installed, clone the repo, move to the docs/ directory and run bundle install. bundle should detect that you are in a ruby directory and install the correct dependencies. Then test that jekyll is working with bundle exec jekyll serve --config _config.yml,_config_dev.yml. This should start the local dev server. Try to nagivate to the shown url to see the blog.

1. Install npm with you favourite tutorial.
2. Move to docs/ts/ and run npm i to install the node dependencies.
3. Test that everything works with npm run buildnwatch

Adapted from https://jekyllrb.com/docs/installation/windows/

1. Download ruby and devkit 2.x.x from https://rubyinstaller.org/downloads/. At the time of writing, this is Ruby+Devkit 2.7.5-1 (x64)
2. Install it and keep the ridk install box ticked. When asked, install the #3 option in the prompt
3. clone the repo, move to the docs/ directory and run bundle install. bundle should detect that you are in a ruby directory and install the correct dependencies.
4. If it fails you might need to run gem install unf_ext -v '0.0.8' --source 'https://rubygems.org/' to install a needed library for Ruby.
5. Test that jekyll is working with bundle exec jekyll serve --config _config.yml,_config_dev.yml. This should start the local dev server. Try to nagivate to the shown url to see the blog.

Same as for ubuntu (see above)

• Watch the ts code and rebundle when their is a change: cd docs/ts && npm run buildnwatch
• Jekyll devserver in watch mode cd docs && bundle exec jekyll serve --config _config.yml,_config_dev.yml
• Watch the scss code to compile it instantly to css cd docs && sass --watch ./sass/main.scss:./generated/css/style.css --style compressed

With these 3 commands in parallel, you can work on the site and see your changes without manually running extra commands.
The ts code is transpiled to js, bundled and minified but the sourcemap to the ts code is served when using the development server.
