[Bug: 21.4.16] User-defined Eshell commands are ignored

================================================================ Dear Bug Team! I define several Eshell alias functions (elisp functions with names of the form 'eshell/foo' which are invoked on the eshell command line as 'foo') in my .emacs file. This worked fine in Emacs, but not in XEmacs, and I've tracked down the problem to the definition of the function `eshell-find-alias-function' in esh-cmd.el. Overridding it with the definition of this function from CVS Emacs' esh-cmd.el solved the problem for me. Here is that definition for your convenience: (defun eshell-find-alias-function (name) "Check whether a function called `eshell/NAME' exists." (let* ((sym (intern-soft (concat "eshell/" name))) (file (symbol-file sym))) ;; If the function exists, but is defined in an eshell module ;; that's not currently enabled, don't report it as found (if (and file (string-match "\\(em\\|esh\\)-\\(.*\\)\\(\\.el\\)?\\'" file)) (let ((module-sym (intern (file-name-sans-extension (file-name-nondirectory (concat "eshell-" (match-string 2 file))))))) (if (and (functionp sym) (or (null module-sym) (eshell-using-module module-sym) (memq module-sym (eshell-subgroups 'eshell)))) sym)) ;; Otherwise, if it's bound, return it. (if (functionp sym) sym)))) ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: FreeBSD niamh.cfhp.org 5.3-RELEASE FreeBSD 5.3-RELEASE #1: Mon Nov 8 12:49:38 PST 2004 root＠niamh.cfhp.org:/usr/obj/usr/src/sys/NIAMH i386 ./configure '--with-clash-detection' '--with-sound=native,nonas,noesd' '--site-includes=/usr/local/include' '--site-libraries=/usr/local/lib' '--with-ldap=no' '--with-site-lisp' '--with-database=berkdb' '--x-libraries=/usr/X11R6/lib' '--x-includes=/usr/X11R6/include' '--prefix=/usr/local' 'i386--freebsd' XEmacs 21.4.16 "Corporate Culture" configured for `i386--freebsd'.
