gojekyll VS just-the-docs

No, plugins are not supported in any meaningful way. With Jekyll I can write "_plugins/foo.rb" and put any code in there, and even monkey-patch core Jekyll code.[1] I can't do this with GoJekyll, because Go doesn't really provide a good mechanism for this.

What it does have is a bunch of optional features that are typically provided by plugins in Jekyll[2], but this is a very different meaning of "plugins" that Jekyll has.

[1]: Whether you should be doing this is a different issue, but I would argue that for a static website builder it's fine, especially since you can just lock the Jekyll version with little downsides, and it doesn't change that often in the first place.

[2]: A list of them: https://github.com/osteele/gojekyll/blob/main/docs/plugins.m...

I think GitHub Pages only supports a whitelist of plugins, so you might have some more difficulties solving it well without any plugins. I use Netlify for my site, which does support arbitrary plugins.

One quick way to make it faster is to include that "_includes/nav.html" only in a nav.html, and then use an iframe to load that on every page, or something like that.

Anyway, I'm not the first to notice this it seems, although even "twice as fast" would still be quite slow: https://github.com/just-the-docs/just-the-docs/issues/1323

If it can help, there was a commenter earlier who suggested trying out a Doc-style github page that you can easily fork. It also has its own built-in search. Comment here. Github page here.

So the basic idea is I use the Jekyll site generator (which is already built into GitHub pages, but you can also install locally), and this is the theme I use: https://just-the-docs.github.io/just-the-docs/

That's certainly an option. Games like Liminal Horror and Into the Dungeon Revived host versions on GitHub. You can then render it to a GitHub.io page using something like Just the Docs.

The pages are written in markdown and the site has an in-built search feature. I am using the https://github.com/just-the-docs/just-the-docs jekyll theme.

The only people that like confluence have Stockholm syndrome. I'd argue that a wiki is the old people way of thinking. In most orgs a wiki is where data goes to die but some asshole keeps throwing data in there to appease some other asshole. I rather search slack, https://github.com/just-the-docs/just-the-docs, project boards in github, anything is better than confluence and I couldn't agree more that confluence search is the biggest piece of shit ever, it's worse than useless, it wastes your time.

Especially if you're already familiar with Jekyll. Bonus points for being able to deploy on GitHub Pages!

You can use 'Just the Docs' (https://github.com/pmarsceill/just-the-docs) for documentation - it's a Jekyll-based theme for documentation and has built-in search.
