            Bug ID: 44373
           Summary: cmd's %0 path variables (e.g. %~dp0) don't match those
                    of Windows (w.r.t. case and quoting)
           Product: Wine
           Version: 3.0-rc6
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
          Assignee: wine-bugs at winehq.org
          Reporter: ryan.prichard at gmail.com

I'm filing this issue at Fabian Maurer's suggestion, after filing
https://bugs.winehq.org/show_bug.cgi?id=44369.

When %0 starts with a quote character, Windows tends to evaluate the %0 path
variables (%~d0, %~p0, ...) strangely. I think the Wine behavior makes more
sense, but it could also make sense to match Windows bug-for-bug.

Test program (you might have to fix up the C:\bin for your machine):

    C:\>mkdir Bin

    C:\Bin\ShowArg0.Cmd:

        @echo [%0] -------------------- [%~d0] [%~p0] [%~n0] [%~x0]

    C:\Bin\RunScript.Cmd

        @echo off
        setlocal
        set PATH=C:\bin;%PATH%
        cd \
        echo --- Wine and Windows roughly do the same thing.
        call showarg0
        call SHOWARG0
        call showarg0.cmd
        call SHOWARG0.CMD
        call C:\bin\showarg0
        call C:\bin\showarg0.cmd
        call c:\bin\showarg0.CMD
        call showarg0".cmd"
        call showarg0."cmd"
        call showarg0.c"md"
        call s"ho"warg0.cmd
        call s"ho"warg0
        call "C:\bin\showarg0.cmd"
        call "c:\bin\showarg0.CMD"
        echo --- Wine and Windows diverge here.
        call "showarg0"
        call "SHOWARG0"
        call "showarg0.cmd"
        call "SHOWARG0.CMD"
        call "showarg0".cmd
        call "sho"warg0.cmd
        call "sho"warg0
        call "C":\bin\showarg0.cmd
        call "C:"\bin\showarg0.cmd
        call "C:\"bin\showarg0.cmd
        call "c:\"bin\showarg0.CMD
        call "C:\bin\showarg0"

(I edited the script output to align the columns.)

Windows behavior (tested on XP and Win10.0.16299.125):

    C:\Bin>RunScript

    C:\Bin>RunScript

    ["C:\"bin\showarg0.cmd] ---- [C:] [\bin\] [showarg0] [.cmd]
    ["c:\"bin\showarg0.CMD] ---- [c:] [\bin\] [showarg0] [.CMD]
    ["C:\bin\showarg0"] -------- [C:] [\bin\] [showarg0] [.CMD]

I see two differences:

 - In most cases, when a path starts with a quote, Windows somehow doesn't
parse the path correctly and/or doesn't find the batch file in the PATH.

 - As long as Windows *does* find the batch file, it uses the canonical case
for the path, filename, and extension. It doesn't canonicalize the drive;
instead it uses the drive from the PATH or %0. I also tested a SMB share on XP
and Win10 (\\nAs\nAs and \\NaS\NaS), and Windows didn't canonicalize the server
name or share name. (Maybe it never does.)
