From the manpage:
Assume that your config file is ipythonrc-<name> (looks in
current dir first, then in IPYTHONDIR). This is a quick way to
keep and load multiple config files for different tasks, espe-
cially if you use the include option of config files. You can
keep a basic IPYTHONDIR/ipythonrc file and then have other
'profiles' which include this one and load extra things for
particular tasks. For example:
1) $HOME/.ipython/ipythonrc : load basic things you always
2) $HOME/.ipython/ipythonrc-math : load (1) and basic math-
3) $HOME/.ipython/ipythonrc-numeric : load (1) and Numeric and
Since it is possible to create an endless loop by having
circular file inclusions, IPython will stop if it reaches 15
The code in ipython which tries to answer what 'home' is follows (from
"""Return the closest possible equivalent to a 'home' directory.
For Posix systems, this is $HOME, and on NT it's $HOMEDRIVE\$HOMEPATH.
Currently only Posix and NT are implemented, a HomeDirError exception is
raised for all other OSes. """ #'
if os.name == 'posix':
elif os.name == 'nt':
# For some strange reason, win9x returns 'nt' for os.name.
# Use the registry to get the 'My Documents' folder.
import _winreg as wreg
key = wreg.OpenKey(wreg.HKEY_CURRENT_USER,
homedir = wreg.QueryValueEx(key,'Personal')
elif os.name == 'dos':
# Desperate, may do absurd things in classic MacOS. May work under DOS.
raise HomeDirError,'support for your operating system not implemented.'
All of this means that under win32, if $HOMEDRIVE\$HOMEPATH is not defined,
then the registry key
Folders\Personal is used. Whether this is a good idea or not, I don't know.
I putzed around until I got somehting that returned reasonable-looking
answers, and that was the end of it. I'm open to suggestions on better
choices for this. Under posix, you just get $HOME, and you're done.
Once this is answered, then ipython makes a .ipython/ subdir below this HOME
directory, and that's where it looks for profiles (which must be named
ipythonrc-FOO to be recognized by 'ipython -p FOO'). So the enthought profile
should be a file called 'ipythonrc-enthought', located in HOME/.ipython/.
FWIW on my friend's system, with a default install, this worked just right.
I hope this helps, and please let me know if you guys need anything else on this.
