I was wondering why I didn't have any CYGROOT set. I agree that
REG_EXPAND_SZ is "nicer" in terms of not hard-coding paths, but since
$CYGROOT is non-standard I don't see that it matters too much.
There's a couple of problems with it still, in the backspaces/quotes
department. Your .reg file installs the command:
"%CYGROOT%\\bin\\bash -c \"echo -n `/bin/cygpath -u
'%l'`>/dev/clipboard\"" + NewLine
When I run the command I get an error. The proper quoting is
"%CYGROOT%\bin\bash" -c "echo -n `/bin/cygpath -u '%l'`>/dev/clipboard"
You don't want to escape the double-quotes because they are there to
tell the windows shell to make all that stuff a single arg, after -c.
You need double quotes around the exe image in the off chance there's a
space in $CYGROOT. And there's the issue of the raw binary newline at
the end. The hexified version of that is
hex(2):22,25,43,59,47,52,4f,4f,54,25,5c,62,69,6e,5c,62,61,73,68,22,20,2d,63,20,22,65,63,68,6f,20,2d,6e,20,60,2f,62,69,6e,2f,63,79,67,70,61,74,68,20,2d,75,20,27,25,6c,27,60,3e,2f,64,65,76,2f,63,6c,69,70,62,6f,61,72,64,22,00

Anyway, the Right Way (IMHO) to do this would be something like the
following:
----- copy_cygpath.c -----
#include <sys/cygwin.h>
#include <windows.h>
int main(int argc, char **argv)
{
HGLOBAL hglbBuffer;
LPTSTR lptstrBuffer;
if(argc != 2) {
// usage: copy_cygpath [win32 path]
return 1;
}
hglbBuffer = GlobalAlloc(GMEM_MOVEABLE, (MAX_PATH +
1)*sizeof(TCHAR));
if (hglbBuffer == NULL) {
return 1;
}
lptstrBuffer = GlobalLock(hglbBuffer);
cygwin_conv_to_full_posix_path(argv[1], lptstrBuffer);
GlobalUnlock(hglbBuffer);
if(OpenClipboard(NULL) == 0) {
// failure!
GlobalFree(hglbBuffer);
return 1;
}
EmptyClipboard();
SetClipboardData(CF_TEXT, hglbBuffer);
CloseClipboard();
return 0;
}
------
$ gcc copy_cygpath.c -o copy_cygpath.exe -mwindows -luser32
$ mv copy_cygpath.exe /bin
Now your registry entry is just:
"%CYGROOT%\bin\copy_cygpath.exe" "%1"
or
------
REGEDIT4
[HKEY_CLASSES_ROOT\Directory\shell\CygPath]
@="&Copy LFN Cygwin Path"
[HKEY_CLASSES_ROOT\Directory\shell\CygPathLFN\Command]
@=hex(2):22,25,43,59,47,52,4f,4f,54,25,5c,62,69,6e,5c,63,6f,70,79,5f,63,79,67,70,61,74,68,2e,65,78,65,22,20,22,25,31,22,00
------
This has the advantage of loading a single process, rather than bash,
echo, and cygpath. You also eliminate the silly console window that
flashes open and then closes.
One might also want to change the C code to backslash escape spaces and
other non-[\w\d] characters. That way you could still work with the
long filenames at the command prompt. Alternatively you could have it
paste the path as '/path/with a/space' (with the quotes.)
