Support for Microsoft Windows High contrast mode in iddiff

[SpencerDawkins]

Description

This may be the lowest priority enhancement request you get in the 2020s, but I wanted to let someone know what I know.

I happened to notice that Windows 10 supports a "High Contrast" setting this morning, and turned it on. Yes, I know this means I am old. 😉

It seems to work well enough for me to want to leave it turned on, but I was just assigned an ART-ART re-review of https://datatracker.ietf.org/doc/draft-ietf-alto-new-transport/, so the next thing I did, was to select the "htmlized" format, and look at a side-by-side diff of -01 (which I had previously reviewed) and -07.

This is what I was looking for (assuming you have something like normal color settings on your computer):

https://author-tools.ietf.org/iddiff?url1=draft-ietf-alto-new-transport-01&url2=draft-ietf-alto-new-transport-07&difftype=--html

This what I got (assuming that I'm attaching a screenshot correctly):

In case the screenshot isn't clear for you, I don't see any color differentiation for new or deleted text, etc. between the two versions.

I have more than one computer, and I can easily enough go find another computer to write my review, or (if I'm traveling and have access to only one computer), turn High contrast mode OFF, but I don't know whether any current or future IETF participants need High contrast mode as more than a convenience, so I thought I'd leave this here, in case the enhancement matters more to other people than it does to me.

Thanks for all you do, by the way. I know these tools don't write, enhance, or fix themselves.

Code of Conduct

• I agree to follow the IETF's Code of Conduct

If this enhancement seems interesting to anyone reading this, most of the people I know who work on IETF tools use iOS computers, so if you'd like someone to investigate further on Windows systems (for example, check out High contrast on Windows 11), please hit me up. I'd be happy to do so ...

We will need to comeup with better colour scheme.

@kesara - thank you for taking a look at this.

I wasn't sure whether changing the colour scheme would fix this problem, or whether High Contrast on Windows was keying off something else. This is what GitHub looks like, in High Contrast, for instance.

Does this look like the colours are being used to show the sharp delimiters (say, around this text box, or is something else happening?

(I ask, because UI is FAR from my area of clue!)

@SpencerDawkins Thanks for offering to help to test on the Windows platform.
Do you have the same issue with
Can you compare outputs:

• https://author-tools.ietf.org/iddiff?url1=draft-ietf-alto-new-transport-01&url2=draft-ietf-alto-new-transport-07&difftype=--html (rfcdiff output)
• https://author-tools.ietf.org/iddiff?url1=draft-ietf-alto-new-transport-01&url2=draft-ietf-alto-new-transport-07&difftype=--html&iddiff=1 (iddiff output)
  Both are worse or if any of those any better?

[SpencerDawkins]

@kesara - my apologies for an insanely late reply (jet lag plus another run through COVID-19 after arriving back in DFW was not helpful).

I took a quick look at the links you provided, and I can't see the difference (nor can I see additions and deletions using either version of the diff tool).

This is iddiff=1

[SpencerDawkins]

I should also say that I turned on high contrast mode with no changes to the default colors. This is what I'm using - it's not clear whether any other colors might be better or worse.

[SpencerDawkins]

Windows 10 has 4 themes - High Contrast ietf-tools/ietf-at-ui#1, ietf-tools/ietf-at-ui#2, White, and Black. I happen to like High Contrast ietf-tools/ietf-at-ui#1 the best, but none of them show any differences between URL 1 and URL 2.

@SpencerDawkins thanks for testing and confirming the issues.

I can confirm it because I am the youngest generation who has gone to work with his elders.
