init file help

[DeSoya]

I'm trying to write bash scripts in emacs but Cygwin was having
problems interpreting the line endings. Someone suggested that I use
the command C-x RET f <unix> to fix the trouble. Sure enough it worked
like a charm. I tried to make this my default by editing my init file.
Unfortunately I'm on XP and there was no default init. I went ahead
and used C-x C-f ~/.emacs.d/init.el to create one. Then I typed (setq
default-buffer-file-coding-system 'unix), saved it and quit out of
emacs to test my creation. When I opened the program back up I got a
error message from my init file. Now it just reads "Invalid coding
system: Unix" in the buffer and I can't actually run any commands.
This means I can't edit the init.el file since I can't open anything.
Anyone have any insight?

It might be better not to specify the UNIX line endings form of all  
encodings but of one specific, for example:

	(setq default-buffer-file-coding-system 'iso-8859-15-unix)


The manual change request might have been interpreted as a wish to  
switch from some variant to the UNIX variant line endings, so it  
could succeed. In your init file no encoding was previously set, so  
there does not seem to be a sense in your statement.

Actually, this is not what the OP wants.  I think he wants this:

  (setq default-buffer-file-coding-system 'undecided-unix)

The advantage of the latter is that it doesn't fix the character
encoding, only the line-endings.

It seems as though my init.el file has disappeared. I can't open it in
emacs due to the error from the bad coding system. I can't find
the .el file using either cygwin or windows. I tried reinstalling but
predictably that didn't work. Is there any way that I can either find
and delete this init file or is there any way I can load using the -q
option through windows? I'm not using the command line since my cygwin
install doesn't seem to like the tar.gz file that I tried to use
before giving up and getting the windows .zip.

Just start Emacs with

   emacs -Q

(note the uppercase Q). Then in Emacs do

   C-x C-f ~/.emacs.d/init.el

to try to open the file. Or you can do

   M-: (file-truename "~/.emacs.d/init.el")

to see where it is.

I can't open the program using the command line for some reason. I
tried the "emacs -q" command in both cygwin and dos and get the
following error:

ndoyle@CMAXP /cygdrive/c/emacs/emacs-22.1/bin
$ emacs -q
bash: emacs: command not found

Use the full path to emacs.exe. It looks like it in your case in cmd.exe 
should:

   c:\emacs\emacs-22.1\bin\emacs -Q

Don't try that from the Cygwin shell prompt.  Instead, open a normal
Windows Command Prompt window, and do it from there.

You mentioned having installed from a *.zip file.  Where did it get
installed?

There should be an emacs or emacs-VERSION directory where the base
install was done.  So inside the emacs* directory you will find a
`bin' directory inside that is both an emacs.exe and runemacs.exe

On windows I think you need to execute runemacs.exe

From a cygwin window run the command using address where you emacs is
installed in place of MYBASE_INSTALL

 MYBASE_INSTALL/emacs/bin/runemacs.exe -Q

Should start your emacs with out loading any of your init files.

This won't find your missing file but at least you can use emacs.

To find the missing file ... from windows explorer right click your
C:\ drive and select `search' from the menu.

Insert the name of the init file.. it may take a while but will
probably find it unless you've installed on a different disk or
somehow moved the init to a different disk.

I think I see what the trouble was.
You were in /cygdrive/c/emacs/emacs-22.1/bin?

So in that case you must indicate the path with `./'

./runemacs.exe -Q

The init file is in your home directory.  Your home directory is
either the one pointed to by the HOME environment variable (if you set
that; Windows by default does not); or "C:\Documents and
Settings\YOUR-USERNAME\Application Data".

That latter part actually depends on the Emacs version. That is the default
location for the current Emacs version. In some older versions, the default
location is C:\.

Right. It should be in C:\Documents and Settings\YOUR-USERNAME
\.emacs.d but it's not. In fact, there is no .el file modified in 2008
on my computer. There was nothing in .emacs.d except for some auto
saved buffers. I tried making a file named _emacs but the program is
still finding this phantom init file. I'm very confused.

What does Emacs display if you type

  M-: (expand-file-name "~") RET

inside Emacs?

No, that's not true.  Emacs does NOT require quotes for .emacs.  Only
the Windows explorer does.

Thanks, I did not know that. But as you mention, Notepad does require it.
