Didier Verna <verna(a)inf.enst.fr&gt; writes: I agree with your proposal. Two comments: * You should make an obsolete isearch- alias so that old compiled code that uses the `with-caps-disable-folding' macro doesn't fail; * FSF Emacs has a different version of `isearch-no-upper-case-p', which perhaps works better. (our has a "fixme" comment.) This is problematic. For all I know, there can be valid user code that uses that macro. Adding an argument will make all that code fail. I think you should choose a different name, or perhaps a new macro (`with-caps-disable-folding-regexp'?) The argument that the changes are affordable because the packages don't use the macro does not stand because we don't know how much user code uses the macros. What we call "packages" is but one part of Lisp code written by our users. With your changes, otherwise perfectly valid code using documented interface will fail in various obscure ways. These two are wrong if you add the REGEXP argument. Didier, you can't add this blob to every function under the sun -- it will be a maintenance nightmare! You should write a modification of the `with-caps-disable-folding' macro and use it consistently. -- Hrvoje Niksic <hniksic(a)srce.hr&gt; | Student at FER Zagreb, Croatia --------------------------------+-------------------------------- "Beware of bugs in the above code; I have only proved it correct, not tried it." -- Donald Knuth
