Why jumping around in text is hardWhy jumping around in text is hardPosted Feb 26, 2008 15:25 UTC (Tue) by anand21 (guest, #38076)In reply to: Why jumping around in text is hard by eru Parent article: Emacs news: new maintainer, version 22 pretest
If you do need to browse a large log file, less is your friend. Editing is a hard problem. Modern editors do a lot of formatting and storing that information takes a lot of space. Concurrent access could be solved by locking but it wouldn't help because the editor must still load the whole file, and then parse it and store temporary information, for providing a consistent view.

Why jumping around in text is hard Posted Feb 28, 2008 20:03 UTC (Thu) by nix (subscriber, #2304) [Link] Locking text files is *really unfriendly*, too. Shades of Windows. (Note that less also sucks the whole file into RAM, so if it's huge less won't do the trick either.) (Emacs doesn't do a lot of *formatting*, as such, but both the Emacsen *can* attach properties/extents/whatever to regions of buffers, and both also have to handle multibyte support to the extent of having single buffers with many encodings in. All of these things push up the memory consumption somewhat, especially the latter.)
