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.

Or some variant of that, in your preferred language. There's loads of things you can do wrong in Jekyll even without any plugins, and this applies to most static site generators.

Anyway, I have a list of plugins at [1]; some are as simple as "don't use leading 0 for dates but a space" so it looks nicer but still aligns well, and others are a bit more crazy such as "use Vim's :TOhtml for syntax highlighting because I think Rouge looks horrible".

Stuff like "show all posts with the same tag as the current post" could be done in pure Liquid template too, but this is usually a lot more awkward and a lot slower, and convenience tags like {% warning %}Watch out!{% endwarning %} are completely unnecessary as such, but it's just convenient and nice.
