XEmacs Info node missing ? 25 years, 9 months

Ian MacKinnon

When I click on the Xemacs node after having done "C-H i" I get "No such node Xemacs", and sure enough in the info directory it's not there. Where does this come from ? All I downloaded was xemacs-21.0-b46.tar.gz This is on NT + cygwin --- Ian

[PATCH] 21.0-b46: hacking on the hook fixes 25 years, 9 months

Kyle Jones

The run_hook_with_args_in_buffer patch neglected the nil case. Ben pointed out a problem with the remove-hook patch.

I am terribly sorry for Andy as looked I was pretend him... It was NOT my intention to pretend someone when I sent previous mail. It is just my post against the Andy's post which is <3.0.3.32.19980630134108.00f74878(a)exchange.parallax.co.uk> Again, sorry for everyone, --HOYANO

Re: Where do you want to go tomorrow? 25 years, 9 months

Michael Sperber

[ Ben: Changing the Lisp engine is not going to affect users much. ] I totally agree with Ben that there are more important immediate issues in XEmacs development than replacement of the Lisp engine, even though swapping the Lisp engine could make a lot of development issues considerably easier. Unexec (first on Ben's list) should be one of first. I disagree, however, that changing the Lisp engine is not going to affect users. The immediate consequence of a new engine is going to be performance; XEmacs runs dog-slow in many areas, and (long-term, not ignoring the recent improvements) it has become slower faster than machines have been getting faster. People have been complaining about other aspects of the system which can only be fixed with a new substrate. Multithreading comes to mind. Also, Emacs Lisp currently is hampering the development work I can do for XEmacs. Programming idioms common among modern programming languages are painful in Emacs Lisp, and as such Emacs Lisp development is, for me, currently at least 3 times as slow as it should be, and considerably less fun. I don't enjoy it much, and thus don't do things which I otherwise would tackle. I'm aware that there are people who say they're currently happy with XEmacs Lisp, but I suspect that there are others who feel as I do, and would produce more and better code if the language substrate were different. I also conjecture that more developers would hack on XEmacs if its extension language weren't so arcane. This kind of thing would indeed affect users. I don't think it'll be necessary to halt all (or even most or a lot of) development in order to prepare and finally do the swap. I, for one, am not very interested in hacking on most of the issues you mention (not because I don't consider them important---for purely personal reasons), but have spent, am spending, and will spend considerable time and effort on the design and implementation issues involved in a swap. None of it has currently been fed into the XEmacs development process; I'll wait until I have something immediately usable. -- Cheers =8-} Chipsy Friede, Völkerverständigung und überhaupt blabla

You're patch is also applied (the one which adds something with gui-default into x-faces.el).

This is a general problem with drafts -- they save no information other than buffer text. In normal cases, this is enough, but it is insufficient for the more advanced Emacs features, where some data is stored in extents/text properties. The same problem will likely pop up when Lars introduces MIME composing to message. -- Hrvoje Niksic <hniksic(a)srce.hr> | Student at FER Zagreb, Croatia --------------------------------+-------------------------------- Personifiers Unite!
