Description
Steps to reproduce
In the following, it is assumed that WinPython is located at C:\Progs\WPy64-3980.
- Open a Windows command prompt
- Change into a directory outside of the WinPython installation location
- Call
C:\Progs\WPy64-3980\Scripts\cmd.bat - This results in a syntax error:
Expected behaviour
The WinPython environment should have been set up successfully.
Reason
After some investigation it turns out that the problem is located in env_for_icons.bat and has been introduced by commit d5d7950
The syntax error is thrown here:
Lines 1382 to 1383 in e1b823e
There, %WINPYWORKDIR1:~-1% is expanded to a ", not \ or another allowed character as expected. This is since %WINPYWORKDIR1 is set in quotationsmarks now due to the commit mentioned above
Lines 1378 to 1379 in e1b823e
Solution
I am not a Windows batch expert but I guess changing
Line 1383 in e1b823e
to
if "%WINPYWORKDIR1:~-2,-1%"=="\" set WINPYWORKDIR1=%WINPYWORKDIR1:~0,-2%"should fix the problem. I tested this on my systems (Windows 8.1 and Windows 10 21H1) and it works. However, I do not overlook all possible side effects. @stonebig If you agree with this approach I can make a PR.
Background
I call cmd.bat from a menu entry in my Windows Explorer context menu "Open WinPython 3.9 command prompt here...". This worked well for years (up to at least WPy64-3950), with WPy64-3980 the mentioned problems occured.
