Diff Feature Comparison
- This feature comparison matrix in it's current existence looks really superficial. It's a good idea, but I don't think very many software articles on WikiPedia serve as running software reviews of different packages. Most of these diff applications are graphical interfaces anyway.
Diff on WikiPedia
NEone know what diff program Wikipedia uses for its page histories, which shows the spefic location in a line where text begins to differ, or what such a program would be called? This seems to be slightly different from the UNIX program which only shows differing lines but not where in the line it differs.
- Wikipedia currently doesn't use diff at all, the history functionality is being done by MediaWiki and is code written in PHP. I imagine this includes the functionality showing results on a word-by-word basis -- 132.198.104.111 17:38, 13 Jul 2004 (UTC)
Layman's Terms
Could some one explain this in layman's terms?
- The diff algorithm is an implementation of the Longest-common subsequence problem, which is now linked to in Diff's "See also" section.
- I've added an example for clarity. I don't say it's a good (or realistic) example, but it will do for now. Without an example it's not clear what a diff really is, or looks like. Shinobu 18:14, 28 Mar 2005 (UTC)
Binary v. Text Sentence in Intro
Apart from that, shouldn't The first editions of the program were designed for line comparisons in text files. By the 1980s, support for binary files was necessary resulting in a shift in the application's design. be in the History section? Just a thought. Shinobu 18:14, 28 Mar 2005 (UTC)
- I agree it seems out of place, but I think it's necessary to somehow mention in the intro that diff handles text and binary data. The sentence is just being a little more specific. No worries.
Why I deleted Unix and the $-sign
I deleted Unix from the intro because there are diffs for every platform. The Unix heritage is discussed in the History section so I think that's okay. I removed the $-sign, because prompts look different on every system (even if one compares two Unixen). Apart from that, most texts illustrating a command to be entered don't display the prompt, because it might be confused with input that has to be entered by the user.
