Update ruleset for consistency and ease-of-use

[ghost]

I recommend making a few changes to the ruleset.xml file so that test runs are more consistent and easier to use/read:

• Use colours for reports by default ('cause why not?)
• Ignore .git directories
• Remove comment about phpcbf (either the comment's not ture and we should remove it, or it is and we should remove the line it refers to as well)
• Remove 'BETA' reference, since we're using this for all PRs in core now

Hey, congratulation for opening issue #1 in this repo! 🎉

All fine with your PR (btw the comment about phpcbf is true, but I don't mind removing it).

Maybe some more feedback re colors turned on by default and removing beta state would be nice.

Well to me, 'beta' means something is still in development and isn't production-ready. And yet that's exactly what we're using this repo for - checking production code before it's committed. Yes we might still change/tweak/fix things as we go, but that's the same with Backdrop, etc. too.

The phpcbf comment says of the following line: "This cli arg is only relevant for phpcbf." The line is: <arg name="tab-width" value="2"/> If that is indeed true, and we're not actually using phpcbf (AFAIK), then should we remove that 'tab-width' argument line then?

As for using colour, here's an example without colour:

And here's one with colour:

So not a big difference, but I think it helps differentiate between errors and warnings, if nothing else.

Re colors: they only work fine with dark mode, otherwise text gets partly unreadable. That's why more feedback makes sense.

Beta or not? Not sure, yet. Honestly, I still think this ruleset is in an early stage of development. That doesn't necessarily mean, we can't declare it "stable". 😏

I use dark mode regularly but still the contrast for red is never good for accessibility whatever the background:

• 4:1 for white
• 5.3:1 for black
• 4.5:1 is pass rate for AA regular text (WCAG 2.1)
• 7:1 is pass rate for AAA regular text.
