I can use python to call the shell with "ipython profile create nbserver" and then to edit the resulting ipython_config.py file. However since I'm in python already, this seems roundabout - is it possible to just use the IPython API directly to do these things?

Is creating an ipython profile, and configuring it, a sensible thing to do using the API, and if so, can anyone give me some pointers?

Here is what we are doing: we added a flag to our program (calico --create-profile) that will create an IPython profile. The main iprofile_config.py only needed a couple of options (c.KernelManager.kernel_cmd) and so we create that file directly. We also recursively copy from a setup directory to the ($ipython locate)/profile_calico/   directory, so that if we ever want to have custom files, we can just drop them into our setup directory, and they'll get copied over when you --create-profile.


We are working on that. 

IPython 2.0 will allow you to create config file in json which will be easier to modify for non-python app and/or to automatize.
Right now the logic loop through all the possible configurable is not pretty and use print in lots of places (like for --help-all). 
So we could refactor it, but this will most-likely be for 3.0 or later. 

We plan on having a API to edit config at some point, but it is not in motion yet.
