However regardless of that you should never re-/untabify the result of diff because patch thinks there are difference and won't apply the chunk. Neither of course should you break lines. I failed hand applying your patch (i.e. get weird errors where the DEFSUBR in syms_of_gpmevent calls assert). Could you please make a new patch? > > How do you suppose this gets enabled?

BTW I don't like the idea of making gpm-mode a C function. You really should do the interface in lisp. Then you can much easier do things like call hooks and avoid loading the C module if we are not on a linux tty etc. > > 0. make sure the case when we have frames on more than one VC works > > There is no way to get this working using GPM, because it requires you to > use a GPM function to read characters from the terminal :-( Jan

That is important too. (if you do a full make you see those too). Jan

Nope, that's not how it works - you tell it what method and it automatically constructs the function name from the console type (tty) and method name (set_mouse_position). I just cheat a little and set the method slots directly. -Bill P.

However if you want to progress from mere coolness to utter enlightenment then you should 0. make sure the case when we have frames on more than one VC works 1. make sure the xterm mouse stuff works. 2. [Bonus points] include the xterm only file that libgpm supports in the source so that if you are not on Linux you still get xterm mouse support. 3. Make XEmacs support the GPM selection protocol.

Unicode changes, non-GNU diffs, non-diff > comparison programs, .... No, I am dead serious. Diff compares text files, if your text encoding has various encodings for the same thing it needs to deal with that. I am all for making sure XEmacs not making gratuitous changes, but if the cost is too high, so be it. Jan

Well, (global-set-key 'backspace 'delete-backward-char) doesn't cut the mustard. Despite "stty erase ^?". However, (global-set-key "\C-h" 'delete-backward-char) works.
