Cygwin Emacs and windows paths

Cygwin Emacs and windows paths

[Leo]

Hi there

Recently I bit the bullet and made the switch from NT Emacs to Cygwin
Emacs. And with this finally the annoying bash error message "cannot
set terminal process group (-1): Inappropriate ioctl for device"
disappeared... :-)

Now my normal Windows paths copied from Windows Explorer don't work
anymore in Emacs - and vice versa. I know I can use `cygpath` to
convert /on the command line/, but is there any integration for this 
in Cygwin Emacs?

Many thanks, Leo

No.  There may actually be some obsolete Cygwin-specific code in 
files.el that's preventing this from working.  It's possible that emacs 
is trying to be too smart instead of letting Cygwin handle the file 
names.  (See, for instance, `convert-standard-filename'.)  I'll take a 
look at it when I get a chance.

But it's generally recommended that you use POSIX-style paths in the 
Cygwin environment.  For example, write `/cygdrive/c/foo' instead of 
`c:\foo'.  To save typing, you can put the following line into /etc/fstab:

   C: /c some_fs binary,posix=0 0 0

Then you can just type `/c/foo'.  See the Cygwin User's Guide for more 
information:

Are there some internal bindings already for this in Cygwin Emacs?

Please reply to the list instead of directly to me.  To avoid messing up 
the threading in the mailing list archives, I'm replying to the original 
thread, with your message to me pasted in.

I do think it's advisable to call cygpath, and I don't know of any 
bindings in the code that you can use.  But I had to do something 
similar once in order to make browse-url work properly on Cygwin.  (In 
that case I had to convert from POSIX paths to Windows paths.)  Take a 
look at the Cygwin-specific code in the function browse-url-file-url in 
lisp/net/browse-url.el.  You may be able to use a similar idea.

Extremely sorry about this. With Apple Mail I use a "modern" Mail client not anymore tailored to classic mailing lists - so I have to set things like Plain-text setting, 70-character wrapping and correct reply-to by hand…

Thanks heaps for this! I had a quick look at browse-url.el and it has the right stuff in there. Cool!

Cheers, Leo

I prefer to wrap everything in a shell script.  This is the one I use,
though I actually use "cygpath -w" because I still use NTemacs
because I don't always start X.

EVAL isn't needed but I make all my shell scripts work with -n or
--dry-run so I can see what would happen.

  #!/bin/sh
  ARGS=();  EVAL=eval;  EMACS=emacs;  AMP='&'
  while [ $# -gt 0 ]; do
      case "$1" in
          -e|--existing)    EMACS='emacsclient --no-wait';  AMP=  ;;
          -n|-nn|--dry-run) EVAL='echo #'                         ;;
          -*|+*)            ARGS[${#ARGS[*]}]="'$1'"              ;;
          *)                ARGS[${#ARGS[*]}]="'$(cygpath "$1")'" ;;
      esac
      shift
  done
  $EVAL $EMACS "${ARGS[@]}" "$AMP"

Ken, you still use NTEmacs? How does *your* NTEmacs cope with the new bash/cygwin environment? Don't you get the "Inappropriate ioctl for device" error?
It would be very convenient to find a way back to NTemacs with cygwin-bash inside it…

I've never seen that error.

But I guess you're talking about running bash inside emacs--which I
never do.  It's been my habit for years, whether on Linux or Cygwin,
to have multiple terminal windows open and to press ALT-TAB to get
to one of them when I need the command line.
