I wouldn't start from here

The tidying of the BlogMore source carries on; sometimes by hand, but also sometimes by using either Copilot/Claude or Gemini to decide how best to nudge the codebase in a desired direction. When I do the latter, if I like the suggestions the agents make, but it looks like a bunch of work and I can't be faffed with all that typing, I get them to do the work; otherwise, I'll do it myself.

I am, however, seeing lots of evidence of what I expected to happen, and anticipated happening: to get to where I would like the code to be, I wouldn't have started here.

I'll stress again, for anyone who hasn't been following along, for anyone who might have landed into the middle of this long thread of AI experimenting, that this was the point and purpose. I wanted to use this tool to build something relatively inconsequential, and which I could likely build myself given the time and the inclination, and also something I would actively use.

So where am I at? My main distaste at the moment is the core generation code. Just a few days ago this was a couple of thousand lines of repetitive code that did the job, but which was a bit messy. There's no question that I would not have written it anything like this. Because of this I've been on a push to try and break it up and tidy it up. While doing this I've been playing Copilot/Claude and Gemini off against each other, to see who does what.

As of the time of writing, the generator is split up, but in a way I wouldn't have done myself either. It's pretty much half a dozen mixin classes in a trench coat, all pretending to be one cohesive class. I feel that's a reasonable solution given where I started, but honestly I wouldn't have started there had I been coding this by hand.

Right at the moment I'm working out the best way forward to tidy up an outcome of this approach that I really don't like. The generator code is littered with lots of # type: ignore[attr-defined] to keep mypy happy, because that's what Claude did when it built all those little mixins. To borrow from the explanation in AGENTS.md, the current makeup looks like this:

MinifyMixin
  └── AssetsMixin          (adds icons, file copying)

DateArchivesMixin
  └── ListingMixin         (adds tag/category listings)

OptionalPagesMixin
  └── PagesMixin           (adds core post/page/index/archive)

SiteGenerator(
    AssetsMixin, ContextMixin, GroupingMixin,
    ListingMixin, PagesMixin, PathsMixin
)

The issue is (for example) that MinifyMixin defines a method _write_html. Meanwhile OptionalPagesMixin and ListingMixin and so on make use of self._write_html. But because there's no direct connection between those two classes and MinifyMixin, mypy complains that _write_html isn't defined. Of course, it isn't defined, because it only becomes available when all those classes climb into the SiteGenerator trench coat and pretend to be a real class.

The ignore direction solves the problem, but it's ugly and it's cheating.

So I then set the two different agents on the path of proposing a solution to this. Both were quite different. Claude (via Copilot) decided that an abstract base class was the solution. Gemini decided that a protocol was the solution. I think I'm siding with Gemini on this one because this is a provides/needs problem, not a "kind of" problem. Even then though, while I sense Gemini has the right approach, I'm not always happy with its implementation of it¹, and once again: it's a cleanup of something I'd sooner not be cleaning up in the first place.

So here's the thing, and this harks back to wondering if the code is that bad: it isn't... but it's also generating work if you look at the code and decide that you want it clean and maintainable.

To get to where I want to go, I wouldn't start from here.

I get why I'm seeing the odd report here and there of people abandoning their code bases, or deciding to rebuild them from scratch by hand. Part of me wants to start a fresh branch, remove almost everything, and rewrite the code so it has feature-parity but in a way where I feel the code is tidy and elegant.

The experiment is working as planned.
