[gregklanderman]

I would like to add an optional second argument to
os.path.abspath() to allow specifying the directory
with respect to which the path should be made
absolute. This would be much like the optional second
argument of the expand-file-name function in emacs:

(expand-file-name NAME &optional DEFAULT-DIRECTORY)

The patch is against python 2.2.2. I am running RH 6.3
linux
but that should not matter.

thanks

And don't forget riscospath.py found in the plat-risc directory in Lib in the source distribution. =)

i can submit a patch for those other versions of abspath.
but i'd rather know whether there is support for this change
before doing that.

Well, depends on what you mean by 'support'. I don't think
anyone seriously objects, but there doesn't seem to be
anyone who really cares either. That usually means that if
you care enough to create a complete implementation
(including tests and documentation changes) yourself, the
patch will be accepted. So please submit a new patch if you
do care enough.

What's your motivating use-case for this?

[gregklanderman]

Well, it's been 4 years and I'd pretty much forgotten about this.. but I believe I had a case where my program had some configuration item - the base directory w.r.t. which other files were to be found. So if you have one of those file names, it's convenient to use abspath() except you don't want it relative to the process' cwd, you want it relative to the configured directory. Anyway, it's no big deal, you can just close this if you want.
