http://en.wikipedia.org/w/index.php?title=Ares_I&action=historysubmit&diff=317703369&oldid=317700423 Note that the highlighted lines are not the lines which have changed. This is minor and probably a lot more than trivial to fix. However, the lines above any of the changes are also highlighted as changed. What's going on here? If I missed a dupe forgive me, I searched and came up with naught.
Differences in whitespace will show up like that. EG, in the first large block of text is in the old revision is: {{Cite web |url= In the new revision: {{Cite web| url= It's kinda of hard to make whitespace in red to show that it changed. Likely INVALID as described.
Well I take that back, since a printable has moved, in this case usually a pipe, if it showed up highlighted it'd make this more apparent. Changing component to wikidiff2.
AutoWikiBrowser has solved this by introducing a darker shade of yellow or green on the characters themselfs. So if: {{Template |Param=Foo |Eater=Bar changed to: {{Template | Param = Foo | Eater = Bar those spaces would would have a darker backgroud color and the diff-view itself is also in Pre-whitespace so not only is in AWB visible where the whitespace has changed also how many. That would make great addition to the difference engine of MediaWiki.
A quick note on how AWB's diff system works. It employs a 3-pass system, as opposed to MediaWiki's 2 steps: 1) Line-level diff 2) Word-level diff 3) Whitespace diff, where whitespace at the end of otherwise matching words is diffed. To render highlighted whitespace properly, it's replaced with non-breaking spaces, thus copy-pasting from diffs can yield unexpected results. Note that I wrote AWB's diff system based on wikidiff2, not PHP diff so if they're different...
Created attachment 10417 [details] The diff with 1.19wmf1 (r114429) and gadget "Display diffs with the new yellow/blue color scheme and design that improves accessibility. (based on r133098)" This looks fixed (since a while ago) with the new wikidiff, made clearer by the new colours of bug 11374. The character where there's a difference seems to always be detected correctly, and the removed/added spaces are mostly correctly highlighted in the relevant column, too. See for instance "Avionics| publisher" -> "Avionics |publisher" and "mdy}}| accessdate" -> "mdy}} |accessdate": correct point highlighted in both, but in the second only the pipe and spaces are not highlighted.
Created attachment 10418 [details] Same diff of "Contractor selection" without style improvements With the old style some parts of the diff were less clear but that wasn't fault of wikidiff anyway.
