--- Comment #2 from Peter Wu <pe...@lekensteyn.nl> ---
Good point about PATHEXT, let's assume if an extension is present, the
interpreter should be correctly installed.
Here I found "ftype" and "assoc" commands which can be helpful:
https://stackoverflow.com/questions/1934675/how-to-execute-python-scripts-in-windows
Documentation in MSDN is a bit sad, the ASSOCF type points to the wrong page.
The shlwapi.h header does have the definitions though. AssocQueryString docs:
https://docs.microsoft.com/en-us/windows/desktop/api/shlwapi/nf-shlwapi-assocquerystringw
There are two potentially useful types, ASSOCSTR_COMMAND and
ASSOCSTR_EXECUTABLE. For ".py", these expand to respectively:
"C:\Windows\py.exe" "%L" %*
C:\Windows.py.exe
When used with unknown extensions and ASSOCF_NONE, it would expand to
respectively:
C:\Windows\system32\rundll32.exe
C:\Windows\System32\shell32.dll,OpenAs_RunDLL %1
C:\Windows\system32\shell32.dll
Use of ASSOCF_INIT_IGNOREUNKNOWN will make the function fail instead.
When used with .com, .exe, .bat, or .cmd, it will be:
"%1" $*
%1
>From what I have read, the Command string is interpreted by Internet Explorer,
but I have not found canonical documentation from MS. The executable value
seems good enough, it would work for .js, .pl, .py, .pyw, etc.
