The emacs pkg hg-histedit (pkg seems abandoned) now allows one to use this command entirely within emacs, the relevant code lines are (defcustom hg-histedit-executable "hg" And the crucial lines in the main function (let ((output-buffer (generate-new-buffer " *hg-histedit*")) (commands (if changeset `(,hg-histedit-executable "histedit" "--rev" ,changeset) `(,hg-histedit-executable "histedit")))) However when run it this way, the editing takes place in /tmp (which is the default for mercurial) and not in the directory of the repository in question. >From the command line this can be changed by 1. Bash TMP=$(hg root) hg histedit (or TMP="$(hg root)" hg histedit 2. Tcsh set TMP=`hg root`; hg histedit $argv Then histedit runs in the directory of said repository. Now my question is: how can I modify the lisp code to have this behavior I just described? The only kludge I found was to write a trivial shell script say myhghistedit.sh and change (defcustom hg-histedit-executable "myhghistedit.sh" But how can I do this in lisp?
