I carry a USB stick to the job. It's got emacs installed on it and
there's a link on my desktop that I click (after inserting the stick)
and emacs fires up. It's nice. I use it every day. With the paucity
of decent editors from Windows, I *need* it.
There's a couple minor hassles though that I'd like to dispense with.
One is that I don't know a way to tell emacs what the HOME directory is.
In the past I've just gone into the registry and change some variable
there. I don't remember where that is or how to do it though. Besides,
I prefer to have the variable defined in my .emacs (which is at the
top-level directory on the USB stick). (After emacs loads, I do "M-x
loadfile RETURN e:/.emacs" and that little task loads up the rest of the
stuff emacs needs to know. But I don't know how tell emacs to make e:/
the home directory.
There is a library usb-setup.el in Emacs+EmacsW32 for this.
Can this .el file be downloaded separately from EmacsW32 to use with the
standard Emacs w32 build? Is it somewhere in nXhtml 1.97 or has it been
removed?
No, at the moment it is only in Emacs+EmacsW32 and I have not had time
to setup a repository for that.
However all that file does is to use the ideas from
http://at-aka.blogspot.com/2006/06/portable-emacs-22050-on-usb.html
and reorganises them a bit. So just look there instead.
Thanks, Lennart. I almost understand the stuff at that link but I can't
see how the variable 'data-directory refers to the right drive letter
until after Emacs is launched from the flash drive. The drive letter
could be G:\ when plugged in today and H:\ tomorrow.
With GnuW32 utils I got as far as producing:
df -a | tail -1 > usbemacs.bat
with the result:
STORE N GO 4021232 1850100 2171132 47% G:\
I am at a loss as to where I should go from here.
Thanks again,
Ed
I've never used emacs, and my Dos batch-writing skills are rusty, so
all I can offer is a conceptual solution. Presumably, your emacs
distribution contains a directory not found on any other drive (e.g.
<drive_letter>:\MyEmacsDir\). Any unique path will do. Simply have
the desk icon start a batch file that begins as follows:
dir C:\MyEmacsDir\
If error: directory not exist, continue : else set variable_1 to 'C'
and then goto Label_1:
dir D:\MyEmacsDir\
If error: directory not exist, continue : else set variable_1 to 'D'
and then goto Label_1:
dir E:\MyEmacsDir\
If error: directory not exist, continue : else set variable_1 to 'E'
and then goto Label_1:
...
Label_1:
set <Emacs_Home> to %variable_1%<desired_path>
execute %variable_1%:\<desired path_name + executable file_name>
