RE: resetting xemacs' idea of home directory

Another choice is to use a new env var set the way you want. Set A to /some/path and then open file $A/thesis. (Works in emacs 20.7.1 for Windows). And, FWIW, no reason not to have an A, B, C, D, ... or however many different path shortcuts you might need. ________________________________ From: Glynn Clements [mailto:glynn＠gclements.plus.com] Sent: Sat 4/26/2008 9:34 PM To: Tim Connors Cc: xemacs-beta(a)xemacs.org Subject: Re: resetting xemacs' idea of home directory Tim Connors wrote: Not easily. XEmacs caches the result of getenv("HOME"), and there isn't any way to un-cache it from lisp. Also, the variable which stores the home directory isn't a lisp variable, so you can't just set or bind it. You could modify e.g. find-file-noselect (e.g. with defadvice) to detect a filename beginning with "~/" and substitute your alternate home directory. You could even intercept expand-file-name if you want the change to affect everything. However, that will get a bit messy, as expand-file-name is a built-in function, so you can't use defadvice, and if you want to override the definition, you'll need to store (symbol-function 'expand-file-name) somewhere so that you can call it from your wrapper. -- Glynn Clements <glynn(a)gclements.plus.com&gt; "Misys" is the trade name for Misys plc (registered in England and Wales).
