Render indent depth changes more clearly Summary: Ref T13161. See PHI723. Our whitespace handling is based on whitespace flags like `diff -bw`, mostly just for historical reasons: long ago, the easiest way to minimize the visual impact of indentation changes was to literally use `diff -bw`. However, this approach is very coarse and has a lot of problems, like detecting `"ab" -> "a b"` as "only a whitespace change" even though this is always semantic. It also causes problems in YAML, Python, etc. Over time, we've added a lot of stuff to mitigate the downsides to this approach. We also no longer get any benefits from this approach being simple: we need faithful diffs as the authoritative source, and have to completely rebuild the diff to `diff -bw` it. In the UI, we have a "whitespace mode" flag. We have the "whitespace matters" configuration. I think ReviewBoard generally has a better approach to indent depth changes than we do (see T13161) where it detects them and renders them in a minimal way with low visual impact. This is ultimately what we want: reduce visual clutter for depth-only changes, but preserve whitespace changes in strings, etc. Move toward detecting and rendering indent depth changes. Followup work: - These should get colorblind colors and the design can probably use a little more tweaking. - The OneUp mode is okay, but could be improved. - Whitespace mode can now be removed completely. - I'm trying to handle tabs correctly, but since we currently mangle them into spaces today, it's hard to be sure I actually got it right.

Track a "Done" state on inline comments Summary: Ref T1460. This just barely works, but throwing it up in case any of it sounds mechanically crazy before we build integrations/UI/etc. Specifically, these are the behaviors: - You can mark your own draft comments as "done" before you submit them. The intent is to let reviewers mark their stuff advisory/minor/not-important before they submit it, to hint to authors that they don't expect the feedback to necessarily be addressed (maybe it's a joke, maybe it's just discussion, maybe it's "consider.."). - You can mark others' published comments as "done" if you're the revision/commit author. The intent is to keep this lightweight by not requiring an audit trail of who marked what done when. If anyone could mark anything done, we'd have to have some way to show who marked stuff. - When you mark stuff done (or unmark it), it goes into a "draft" state, where you see the change but others don't see it yet. The intent is twofold: - Be consistent with how inlines work. - Allow us to publish a "epriestley updated this revision + epriestley marked 15 inlines as done" story later if we want. This seems more useful than publishing 15 "epriestley marked one thing as done" stories. - The actual bit where done-ness publishes isn't implemented. - UI is bare bones. - No integration with the rest of the UI yet.

Behold! Copy text from either side of a diff! Summary: Ref T12822. Ref T13161. By default, when users select text from a diff and copy it to the clipboard, they get both sides of the diff and all the line numbers. This is usually not what they intended to copy. As of D20188, we use `content: attr(...)` to render line numbers. No browser copies this text, so that fixes line numbers. We can use "user-select" CSS to visually prevent selection of line numbers and other stuff we don't want to copy. In Firefox and Chrome, "user-select" also applies to copied text, so getting "user-select" on the right nodes is largely good enough to do what we want. In Safari, "user-select" is only visual, so we always need to crawl the DOM to figure out what text to pull out of it anyway. In all browsers, we likely want to crawl the DOM anyway because this will let us show one piece of text and copy a different piece of text. We probably want to do this in the future to preserve "\t" tabs, and possibly to let us render certain character codes in one way but copy their original values. For example, we could render "\x07" as "␇". Finally, we have to figure out which side of the diff we're copying from. The rule here is: - If you start the selection by clicking somewhere on the left or right side of the diff, that's what you're copying. - Otherwise, use normal document copy rules. So the overall flow here is: - Listen for clicks. - When the user clicks the left or right side of the diff, store what they clicked. - When a selection starts, and something is actually selected, check if it was initiated by clicking a diff. If it was, apply a visual effect to get "user-select" where it needs to go and show the user what we think they're doing and what we're going to copy. - (Then, try to handle a bunch of degenerate cases where you start a selection and then click inside that selection.) - When a user clicks elsewhere or ends the selection with nothing selected, clear the selection mode. - When a user copies text, if we have an active selection mode, pull all the selected nodes out of the DOM and filter out the ones we don't want to copy, then stitch the text back together. Although I believe this didn't work well in ~2010, it appears to work well today. Test Plan: This mostly seems to work in Safari, Chrome, and Firefox. T12822 has some errata. I haven't tested touch events but am satisfied if the touch event story is anything better than "permanently destroys data".

Behold! Copy text from either side of a diff! Summary: Ref T12822. Ref T13161. By default, when users select text from a diff and copy it to the clipboard, they get both sides of the diff and all the line numbers. This is usually not what they intended to copy. As of D20188, we use `content: attr(...)` to render line numbers. No browser copies this text, so that fixes line numbers. We can use "user-select" CSS to visually prevent selection of line numbers and other stuff we don't want to copy. In Firefox and Chrome, "user-select" also applies to copied text, so getting "user-select" on the right nodes is largely good enough to do what we want. In Safari, "user-select" is only visual, so we always need to crawl the DOM to figure out what text to pull out of it anyway. In all browsers, we likely want to crawl the DOM anyway because this will let us show one piece of text and copy a different piece of text. We probably want to do this in the future to preserve "\t" tabs, and possibly to let us render certain character codes in one way but copy their original values. For example, we could render "\x07" as "␇". Finally, we have to figure out which side of the diff we're copying from. The rule here is: - If you start the selection by clicking somewhere on the left or right side of the diff, that's what you're copying. - Otherwise, use normal document copy rules. So the overall flow here is: - Listen for clicks. - When the user clicks the left or right side of the diff, store what they clicked. - When a selection starts, and something is actually selected, check if it was initiated by clicking a diff. If it was, apply a visual effect to get "user-select" where it needs to go and show the user what we think they're doing and what we're going to copy. - (Then, try to handle a bunch of degenerate cases where you start a selection and then click inside that selection.) - When a user clicks elsewhere or ends the selection with nothing selected, clear the selection mode. - When a user copies text, if we have an active selection mode, pull all the selected nodes out of the DOM and filter out the ones we don't want to copy, then stitch the text back together. Although I believe this didn't work well in ~2010, it appears to work well today. Test Plan: This mostly seems to work in Safari, Chrome, and Firefox. T12822 has some errata. I haven't tested touch events but am satisfied if the touch event story is anything better than "permanently destroys data".
