Wikipedia:History bug reports

Diff colors

Diff pages speak of green and yellow being the colors of respectively the changed text and the old text. This is useless to those who set their own text colours and not very nice to visually impaired people working on wikipedia. It would be handier if the main way to recognize which is which would be a text (such as: "The new text:" and "The old text:"). Of course, colours could still be used complementary, but they should not be the primary way of distinguishing the two atoms of a diff.--branko

Currently, a - or + will appear next to a deleted or added line. So the bug is not in diff but rather in the documentation. Anyone want to fix it? --Damian Yerrick

Zero disappearing from diffs

The numeral "0" doesn't show up in the text of a diff when it comes immediately after a bracketing delimiter ("(", "[", "{"). See the history of unit interval for examples of each of these. In the HTML source of the diff file, the "0" simply isn't there. The problem doesn't happen with other numerals. -- Toby (2002/04/17)

There's a fun "feature" in PHP whereby the string "0" is sometimes considered to be equal to the empty string "" because, as far as I can tell, a numerical comparison is being used. This sounds suspiciously like an instance of that problem; I'll look into it... Brion VIBBER, Wednesday, April 17, 2002
