Add support for icdiff - side by side colorized diffs!

[rcampbel3]

tig is great! But since I've discovered icdiff, I really prefer to see my diffs side by side. It would be great if there were an option to support using a different diff tool - specifically icdiff.

Thanks!

some form of side-by-side diff would make tig perfect for me, personally I'm not very used to raw-diff viewing.

We got it. Please consider providing a patch / more constructive feedback, instead of posting useless comments. There is a way to just +1 the issue itself or other comments for a reason.

There is not much to expect from posting "+1", except for a rant like this and having wasted time across the glob for people having to read it. And please do not follow up on my comment, except for with a link to a PR or something more constructive.

To conclude: a lot of people seem to like side-by-side, but nobody has done it yet. You might guess that @jonas uses a small screen by default himself maybe, where this is less useful.. ;)

To provide alternatives in this ticket, I'll throw in ydiff, as I prefer its side-by-side diffs compared to icdiff.

ydiff -s -w80 --wrap -U10

Ultimately, I would prefer vimdiff integration (https://github.com/jonas/tig/issues/26), but this would be a good first step.
