[PATCH] Add window-utils.el with resize-temp-buffer-window to xemacs-base. 15 years, 8 months

This is a first draught, with the bug that temp-buffer-show-hook is normally ignored in both 21.4 and 21.5; it seems to be necessary to set a new value for temp-buffer-show-function, probably with the contents ofs #'show-temp-buffer-in-current-frame included. 2008-08-29 Aidan Kehoe <kehoea(a)parhasard.net> * window-utils.el: New. Import some functions from window.el and help.el in GNU. In particular window-buffer-height, count-screen-lines, fit-window-to-buffer, temp-buffer-resize-mode, resize-temp-buffer-window. Also the customizable variable temp-buffer-show-height. * Makefile: Add window-utils.elc.

Re: [COMMIT] sync up with latest GPLv2 version of eshell-mode (2.4.2) 15 years, 8 months

For things that we haven't implemented at all, it's more appropriate to put it elsewhere--help.el (where the code is in GNU) is in core, though, and there's nothing 21.5-specific about it, it would be better in xemacs-base somewhere. Maybe in a file on its own, none of the current files there seem like an expected home for it to me. -- ¿Dónde estará ahora mi sobrino Yoghurtu Nghé, que tuvo que huir precipitadamente de la aldea por culpa de la escasez de rinocerontes? _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-patches

[PATCH] (revised) Handle varalias chains, custom variables in #'user-variable-p. 15 years, 8 months

Aidan Kehoe

Ar an tríú lá is fiche de mí Lúnasa, scríobh John Paul Wallington: > > +\(defmacro portable-defvaralias (variable aliased &optional docstring) > > + \(if (featurep 'xemacs) > > + `(defvaralias ,variable ,＠(cons aliased (if docstring (list docstring)))) > > + `(defvaralias ,aliased ,＠(cons variable (if docstring (list docstring)))))) > > Are you sure about this? I was, but now that I check again I see that the existing variable I was using to check on GNU wasn’t actually available there, which led me astray, and your description is exactly right. Thanks for the correction, here’s a revised patch. SUPERSEDES 18607.61913.395428.309154(a)parhasard.net # HG changeset patch # User Aidan Kehoe <kehoea(a)parhasard.net> # Date 1219502331 -7200 # Node ID 052eccec3209acf24c8cd4235d770815a0aa3e03 # Parent c4fd85dd95bd72e8c7899ed48075c2fb26e365fa Handle varalias chains, custom variables in #'user-variable-p. src/ChangeLog addition: 2008-08-23 Aidan Kehoe <kehoea(a)parhasard.net> * eval.c (Fuser_variable_p): Moved to symbols.c * symbols.c (Fcustom_variable_p): Moved here from custom.el. (user_variable_alias_check_fun): Mapper function used in `user-variable-p'. (Fuser_variable_p): Moved here from eval.c, to allow it to examine the variable alias chain. Expanded to check each entry in the variable alias chain for signs of being a user variable; documentation updated, noting the differences between GNU's behaviour and ours (ours is a little more sensible) (map_varalias_chain): New. Given a C function, call it at least once for each symbol in a symbol's varalias chain, signalling an error if there's a cycle, and returning immediately if the function returns something other than Qzero. (Fdefvaralias): Correct the use of the word "alias" in the docstring and in the argument name. Motivate this in a comment.
