bug#8783: 24.0.50; emacsclientw.exe behaviour in win32 not the same as in linux

[Jason Lewis]

Hi,

When I try to launch emacs in win32 using emacsclientw.exe it does not
seem to work as expected.

on my linux box if I start emacs with either:

emacsclient -c -a ""
emacsclient -c -a "" somefile.txt

it will start emacs in daemon mode or start a client as necessary

however on windows with the slightly different version:

C:\Users\jason\AppData\Roaming>"c:\Program Files
(x86)\Emacs\emacs\bin\emacsclientw.exe" -c
--alternate-editor="c:\Program Files
(x86)\Emacs\emacs\bin\runemacs.exe" test.txt

it will open a new emacs instance editing text.txt

but then if you run:

C:\Users\jason\AppData\Roaming>"c:\Program Files
(x86)\Emacs\emacs\bin\emacsclientw.exe" -c
--alternate-editor="c:\Program Files
(x86)\Emacs\emacs\bin\runemacs.exe" someotherfile.txt

it fails to open someotherfile.txt in the existing frame (and does not
create a new frame either)

further more, while emacs is already running
if you run:

C:\Users\jason\AppData\Roaming>"c:\Program Files
(x86)\Emacs\emacs\bin\emacsclientw.exe" --alternate-editor="c:\Program
Files (x86)\Emacs\emacs\bin\runemacs.exe" test.txt    (no -c option)
emacs will correctly open the desired file

however:
C:\Users\jason\AppData\Roaming>"c:\Program Files
(x86)\Emacs\emacs\bin\emacsclientw.exe" --alternate-editor="c:\Program
Files (x86)\Emacs\emacs\bin\runemacs.exe"     (no -c option and no
file name to open)

emacs gives the error: file name or argument required, in a window and
then aborts and does not either open emacs, nor go to the emacs frame
if it is already running.

This does not seem to be the desired behaviour overall. it makes it
difficult to make 1 command to either launch emacs or open an existing
instance of emacs with a new file.
