functionality. Am I wrong?
`cd' changes the "default directory" of the current
buffer - e.g., so when you `find-file' in that buffer,
the prompt will by default be pointed at that
directory, as the most likely place you would want to
look.
I don't really get what you want
Well, I have many projects which paths are long and it is very often
required to `cd' to one of them. Very often and time consuming. For a shell
I resolved such an issue by means of creating system user (I'm on Linux)
and now I can just (with auto completion and quite nice representation in
the PS1):
cd ~username
where username is a system user's home directory which is the project
root. Well, `username' in my case is just a project's name.
Such thing is quite good and handy for me and I would like the same but in
Emacs, thus I want to be able to change "default directory" of the current
buffer to the user's home directory.
I just wrote these simple functions which does allow to do described thing:
(defun system-users ()
(split-string
(shell-command-to-string "grep -o '^[^:]*' /etc/passwd | tr '\n' ' '") " "))
(defun cu (user)
"cd to the USER's home directory."
(interactive
(list
(completing-read "User: " (system-users))))
(setq default-directory
(replace-regexp-in-string "\n" "" (shell-command-to-string
(format "grep %s /etc/passwd | cut -f 6
-d :" user))))
(call-interactively 'ido-find-file))
Well, it doesn't change default-directory but just calls ido-find-file with
the user's home directory which is good.
Now I just wonder: is there any similar functionality in Emacs? Is there
any way to cd to specific user's home directory?
P.S. I'm sorry for the previous mail personally sent to you before.
- with dired, to show
the home directory's files:
(dired "~")
or perhaps:
(dired (getenv "HOME"))
- is that what you look for?
