Re: What to do with modules now ... 25 years, 10 months

My feeling is that if this is the sort of thing that can be free, or nearly free in terms of implementation cost, cool. Otherwise, it's probably not worth it.

The sort of people who don't like X11 (and GUI) code in Emacs are the ones who tend to not use XEmacs. My only uses of XEmacs in a fielded commercial setting haven't involved usage with X11, but it hasn't been a hardship building it without X11 in the first place. > It's hard to believe that the bug count would decrease as a result > of this, either.

Using CVS 25 years, 10 months

Alastair Burt

Could anyone point me to some information on getting the XEmacs versions from the CVS repository. I have just tried to install XEmacs 21 with Mule using this method and failed. XEmacs without Mule compiled and installed OK. Maybe I need get a Mule package first? Could someone also please tell me the tricks I need to get Mule and non-Mule versions of XEmacs to be installed in the same tree without the DOC files clashing. --- Alastair

Re: Beware of modules. 25 years, 10 months

Olivier Galibert <galibert(a)pobox.com> writes: > May I hear technical arguments _for_ modules for a change ? > > OG. Yes, here's one. As part of my research, I am working on a multi-lingual program analysis engine. I need a front-end. Actually, I need many front-ends: an editor, a couple of graphical tools, may be a batch tool. So, what do I do? Invent an extension engine? 10 years ago I would have done just that, but now I a have more appealing alternative: I instrument the analysis engine as a dynamic library with language bindings du jour. You want to hack in perl? I give you perl bindings. Tcl? No problem. Java? We have that. An editor? XEmacs! This is why *I* want modules in XEmacs. I don't really care about TTY code not being loaded when I am using X; or vice versa. (Although I admit that splitting things like HTML parser would be a good engineering decision). I need extensibility; I need even more extensibility than XEmacs lisp gives me, and modules do just that. Marat.

I hoped you wouldn't ask this. The short answer is: no, it's not a bad idea at all. Long answer: when designing `delete-key-deletes-forward', one of the more important design goal was for it to be safe to set it to t, no matter what, and have the underlying mechanism do the right thing. One of the reasons reasons I refuse to have backspace generate delete is to catch bugs of this sort. > If the problem is with t being the default, then maybe the default > should be changed from t to something which checks the value of > (x-keysym-on-keyboard-p 'backspace) under X. No, the default value of t is exactly right. If everything is coded correctly (like c-mode is), everything will work, even with multiple consoles.

Re: BAD BAD bloat (was Re: What to do with modules now ...) 25 years, 10 months

Tor Arntsen

(Warning, I'm an old-time Linux user and my rantings may not be so interesting for everybody :-) >: Linux workstation), all in 32MB of memory. ... >I've managed to do some fairly serious development on a 32Mb P233 >Linux box with X, XEmacs, make and egcs going full tilt. I think this ... My box is a 16MB Linux 486 PC, by making the kernel as small as possible and using fvwm1 I'm doing fine. xemacs, tons of xterms (all running -sl 1024 scrollback buffer), compiles, ddd, intranet web server (wn), http proxy, ntp proxy, firewall. Everything always running, and used, 24*7. NO problem. XEmacs is slow to start, but fine after that. Netscape is really too slow to start. When it's running it's fine, although I hate using the mouse more and more so I prefer lynx now (must faster anyway). This box has run Linux since April/May 1992, and I have used it full time (in my job) since June the same year. It is incredible what you can do with 16MB in Linux, *if* you just shrink the kernel a bit and avoid the bloated window managers and all that. And how reliable these old boxes (1991 model) are.. I've had uptimes over a year. Only a power break can stop it. I have this 32 MB Indy in the corner, it was always much slower to work with (I could type faster than XEmacs could update the screen). Haven't had it powered up for a year or two, except for checking up on the clock battery. On the road I use a 20MB 486 laptop, XEmacs runs fine there as well. I *am* going to (finally) get a new machine, not because of the fact that I can't add more memory to the box (no problem, hey I compiled Mozilla!), it's because 1) you can't buy any decent vga adapters for ISA anymore (and my old tseng's slow xterm scrolling is finally getting on my nerves), and 2) I'm doing more and more of really big compiles and I'm getting a bit impatient. The new boxes seems to be quite fast now.. (on the other hand I doubt they can build xemacs in two minutes yet, as I did on an SGI PChallenge.. or maybe they can? Hm, should get myself an SMP box I think). Of course it matters a bit that the other guys in the next offices are finally getting ahead of me, as they now have new fast Linux PCs instead of those slow bloated Suns, Indys and HPs they used to have (my PC was better than any of them). Small is fine, but if the executable only loads a few of its (many) disk pages anyway then that *is* small.. Linux VM is good. - Tor
