I just install to the default c:\pythonxy directories (although I like
the idea of a common root) and I put NTFS hardlinks into my general
c:\tools directory which is on the path. The out-of-context hardlinks
work because of the registry settings which pick up the correct context
for each version.
Sorry to be daft here, but what do you mean by a "hardlink" ?
A windows "Shortcut" ?
I have just installed 2.7 and want to start upgrading some code, but
alas still want to maintain some 2.5 code too.
Hardlinks have always been present on NTFS, just not very widely advertised.
They are a way of saying that *this* file and *that* file are actually the
*same* file. (They must be on the same volume as they underlying
implementation
relies on pointing to the volume's master index -- the MFT).
They're not copies: if one changes, the other changes.
They're not shortcuts, which are a Shell (ie Desktop) mechanism, not a
filesystem one
I have hardlinks called python26.exe, python31.exe, etc. which point to
c:\python26\python.exe, c:\python31\python.exe etc. and also
a python3.exe which is another link to c:\python31\python.exe but which will
move when python 3.2 is released.
However, this is simply a convenience I use. It's perfectly possible to have
and to use several versions of Python concurrently without this. How you do
it depends on your working practice: whether you use an IDE or
double-click on
.py files or run from a cmd window, etc.
