Switch Theme To Furo

[GrahamSH-LLK]

Furo

• Is a noticeably better looking theme than RTD
• Waaaay easier to navigate sidebar
• Table of contents on the side (currently unused space on rtd-theme)
  • Makes viewing and finding content on long pages WAY easier
• Is significantly more responsive on small screens
• Has a built in and good looking dark mode
• Is more maintained than RTD-theme (often taking months to release new version that are compatible with sphinx)
• More modern looking admonitions
• Better colors and font
• Used by CTRE :)

I think @Daltz333 might be the best judge if and how this change could be made. As is there are multiple things I don't like about the current implementation:

• The upper left logo looks bad and is far too elongated. I think a lot of effort has gone into the previous one and it should be very similar to that:
  
• Is there any way we can keep the font sizing more similar. It seems to have made many things bigger which throws some things off. For example the "FIRST Robotics Competition Control System" on the home page now is taking two line as opposed to 1.
• On my screen it seems like it has semi centered the page. More gap on the right than left. I think I prefer left justified but not a hill I would die on maybe I am just resistant to change.
• The rounded search box looked better to me.
• The scroll on the left hand side only moves the topics and not the logo above. I don't think we need to see the logo the whole time.
• It seems like the spacing and size of the items on the left is larger and you now need to scroll forever to reach the bottom.
• Do all the links have to be underlined? That seems like it sets them even further apart from the text where as the old theme blended better.

Overall I like many of the features this brings I think we just need to have a deeper discussion on many of the "fine" points.

Check out the sidebar changes I just pushed. It looks way better to me. The rest I'd like to get some more opinions before changing, as I've heard very different takes on them from different people.

On the topic of looks, the people who's opinion matters most are @Kevin-OConnor (FiRST) and @arbessette (WPI). I suspect they're both busy until after championships.

[Kevin-OConnor]

Yep, pretty swamped through Champs and recovering the week after. Just set myself a calendar notification for the 29th to look at this. Sorry for the delay!

Overall I think this looks much better than when I first looked at it. Couple comments:

• On my laptop screen the sidebar looks a little odd. I think it's a result of the overall content being centered, but the padding on the left that's the dark blue sidebar color stands out much more than the white/black padding on the right. I've included an image below. I'm not sure what exactly to do different though.
• In dark mode the green/teal headers on the homepage look a little ugly to me. I don't think this should be a blocker to merging, this is always something that could be changed later.

I like the "On this page" mini table of contents that's part of this. I like the larger text size for the title, I think it helps convey the hierarchy a little better, the text sizes are pretty close between titles and various heading levels in the current theme.

It doesn't look particularly weird to me on my laptop, but I can see how it would to others/on different resolutions. I'm not entirely sure how to fix this either- we could reduce the padding, but I feel like that might look worse.

I can definitely change colors. Which color specifically?

Before merging I would like to get somebody who understands one of the RTL language(s?) to make sure I didn't break anything in the change. I tried to keep everything looking like it did on the old version, but it is very possible that I missed something.

Is there a way to build the Hebrew translation with the changes here? I can see if it's broken, but I'm not familiar enough with RTD/CSS/etc to know in advance.

Does furo use system fonts by default?

[Starlight220]

@GrahamSH-LLK thanks for the build!

Some panel buttons on the homepage lost the framed link:
It seems to be that way with all the Hebrew buttons on that page; I'm starting to suspect that a lot got broken.

The headings sidebar opens properly, but the TOC sidebar doesn't open.

Another note (not only RTL), I'm not sure I'm a fan of the blockquoting here:

This might be a problem in the source itself (note the difference in capitalization of the language labels):

Believe it or not, those buttons seem to be missing on stable Hebrew too. I'm not sure if this is intentional, but it's not a regression in this PR.

That was just fixed (see https://he.grahamsh.com)

What do you dislike exactly?

That must be a mistake from an earlier PR of mine where sphinx tabs were migrated. I'll send a PR to make it consistent soon.

Buttons: bummer it's an upstream limitation, but oh well.

TOC sidebar: fixed; thanks!

Changelog blockquote: I'm not entirely a fan of the seemingly-arbitrary blockquoting of nested lists. Why not keep it without blockquotes? Just seems a bit weird imo that part of the changelog is quoted and some isn't, but it's probably a matter of taste so I won't object.

Tab labels: sounds good.

Overall, LGTM!

sphinx-rtd-theme should be able to be removed from pyproject.toml

I agree, that looks weird. That doesn't happen here with nested lists: https://sphinx-themes.org/sample-sites/furo/kitchen-sink/lists/

This is why: pradyunsg/furo#190

Should probably find places with 4 space indents and fix, seems like it could show up many places.

There's conflicts to resolve

The interactive pid tuning is broken

[rzblue]

The js files are being added to the html past the content, so they're not available at the js entrypoint in the article. Wrapping the entrypoint in a load event listener fixes it
e.g.

<script>
   addEventListener("load", (event) => {
      flywheel_pid = new FlywheelPIDF("flywheel_feedforward", "feedforward");
   });
</script>
