Home directory has no space for .isochrones #170

Hi,

I have successfully installed isochrones (I think) on a remote server and have tried running nosetests. This fails because it attempts to save data to ~/.isochrones but my home directory has very limited space. Is there a way of changing the default directory for .isochrones?

I have exactly the same problem.

I may have just worked around it by editing the 'isochrones/config.py' file (installed by pip per the installation instructions). I changed

os.path.expanduser(os.path.join("~", ".isochrones"))

to

"my_path/.isochrones"

where my_path is the directory, other than /home, where I want .isochrones to be written.

So far so good, but hopefully that didn't break something else...

Rather than changing the source code (which will work for you, but isn't an ideal solution), you can also define an ISOCHRONES environment variable; e.g.

export ISOCHRONES=/path/to/dir/with/more/space/.isochrones

Another solution that I've used is to create a symbolic link from ~/.isochrones to wherever you want the data to go. I've used the same trick for other packages that create local caches.
