Even disregarding the principle of not making the feature *too* clever, he has actually come up with an example where your logic would fail (emacs -> EMACS).

Micheal, is it possible to change the underlying implementation and Lisp API, but still have `-u' work? For instance, we could have a `user-startup-directory' that defaults, say, to "~/", and which `xemacs -u joe' would set to "~joe/", etc. Then correct startup code would do things like: (expand-file-name ".gnus" user-startup-directory) A note for Didier and Kyle: please note that Michael is right about the code already not using `-u' correctly. I'm fairly certain that it never worked right with Gnus. Even if we don't lose the feature, it could certainly stand changing.

The behavior you want appears to me very likely to change from search to search. That's the reason why I hate case-fold-search. It says more or less "you (don't) want case sensitivity all the time". It's stupid. Case sensitivity is heavily dependant on the precise search you're doing right now. - A function argument would be fine, but these functions have already a prefix.

The whole point is that you can't tell. Maybe Joe wants lowercase `blabla' to be replaced (lie I do most of the time), or maybe not. You just can't tell. However, there's a big difference in finding an uppercase letter in FROM because there's no reason to type uppercase letters in there, unless you actually want case sensitivity. There, you *can* tell[1]. > i mean, if i don't put any uppercase letters in FROM but specifically > put some in TO, does it not mean i _want_ case-sensitivity ? Well, no. If I want to convert all instances of "emacs" and "Emacs" to "EMACS", sure I don't want case sensitivity. I'm happy to do a `replace "emacs" with "EMACS"' without case sensitivity. BTW, the real problem is that case-fold-search is an abomination though. We have to cope with it.

No. You search for a /pattern/, you replace with a /string/. If you have `case-fold-search' to non-nil, it's convenient that XEmacs notice the uppercase character in FROM, and deduce that you actually want case sensitiveness. Moerover it's coherent with what interactive searches do. It doesn't make sense to toggle case sensitiveness according to the TO string. > so it did after all what i wanted, but still it did match 'ObjectName' > which i didn't want it to match. actually i think it would make sense to > make it case-sensitive if there are case in any of the 2 arguments . Again, no, because what you want to do is more complex than what the feature is for. You actually want a different treatment for one character in the string, being uppercase or lowercase. That's the kind of thing query-replace-regexp is for. You can query-replace-regexp "object[n\\|N]ame", in which XEmacs will notice the uppercase letter and deduce you want temporarily case sensitiveness. This won't match "ObjectName". For really complex stuff, you'll have no choice but toggle manually case sensitiveness as you wish, but this is a good thing. Let's not complicate the existing functions. And writing `query-replace-with-case' takes 3 lines. > tell me i am wrong, or better make this an option, or am i so wrong i > don't deserve an option ? :-/ You're so wrong you don't deserve an option :-) -- / / _ _ Didier Verna http://www.inf.enst.fr/~verna/ - / / - / / /_/ / ENST, INFRES C201.1 mailto:verna＠inf.enst.fr /_/ / /_/ / /__ / 46 rue Barrault Tel. +33 (1) 45 81 73 46 75013 Paris, France Fax. +33 (1) 45 81 31 19

Two files need patching: glyphs-x.c: 4 instances where IMAGE_INSTANCE_X_MASK is used like this: IMAGE_INSTANCE_X_MASK (p) = <something>; The HP compiler gives this: Pixmap p ; void *val ; val = (void*) p ; // correct. (Pixmap)val = p ; // Wrong: Modifiable lvalue required for assignment operator (around lines 405, 843, 1375, 1981). redisplay-output.c: 2 instances where a struct is initialized from runtime computed values, which the compiler chokes on. (around lines 1240: struct display_box ,1248: struct display_glyph_area). I've #ifdef'ed the changes I made for HPUX10, but they should be safe for any compiler, although they may lead to additionnal warnings about conversions between pointers/integer in glyphs-x.c. Should I send the diff file with the ifdefs, without?

case-sensitivity: bug or feature in query-replace? 25 years, 3 months

Stef Epardaud

following the recent patch on isearch about case-sensitive searches, i've been using query-replace to fix a file where i typed 'objectname' instead of 'objectName' (the 'N' is important), but i already had about a thousand instances of 'objectName' around and several 'ObjectName' as well. so i wanted to replace all instances of 'objectname' with 'objectName', and the replace matched all three forms. now i know the replace is case-sensitive if the FROM argument has case, but should it not be case sensitive as well if the TO argument has case when the FROM does not have ? or would it make sense not to? anyways, the replace worked for all instances, because objectname => objectName ObjectName => ObjectName objectName => objectName so it did after all what i wanted, but still it did match 'ObjectName' which i didn't want it to match. actually i think it would make sense to make it case-sensitive if there are case in any of the 2 arguments . tell me i am wrong, or better make this an option, or am i so wrong i don't deserve an option ? :-/ -- # Stef Epardaud, # There is no limit to the power of computing ... # Java Defeater # ... except men maybe ? # Earth # Lunatech Research, # Solar System # soon we will quit researching and start finding...

I whole-heartedly agree with Kyle. I'm usually pissed off by backward compatibility, but this time I'm sure we can't afford losing "-u". It simply /is/ convenient for many things included the situations Kyle describes, and many others (debugging somebody else's code, using settings from a project's account etc). The fact that some stuff requires the location of ~/.xemacs before the command line is read sounds broken at a very low level. Isn't it possible to fix this, maybe even by making a special early treatment for -u ? -- / / _ _ Didier Verna http://www.inf.enst.fr/~verna/ - / / - / / /_/ / ENST, INFRES C201.1 mailto:verna＠inf.enst.fr /_/ / /_/ / /__ / 46 rue Barrault Tel. +33 (1) 45 81 73 46 75013 Paris, France Fax. +33 (1) 45 81 31 19
