3 * IPython/Magic.py (Macro): simplified Macro class to just
4 subclass list. We've had only 2.2 compatibility for a very long
5 time, yet I was still avoiding subclassing the builtin types. No
6 more (I'm also starting to use properties, though I won't shift to
7 2.3-specific features quite yet).
8
9 * IPython/iplib.py (InteractiveShell.post_config_initialization):
10 changed the default logfile name from 'ipython.log' to
11 'ipython_log.py'. These logs are real python files, and now that
12 we have much better multiline support, people are more likely to
13 want to use them as such. Might as well name them correctly.
14
15 * IPython/Magic.py: substantial cleanup. While we can't stop
16 using magics as mixins, due to the existing customizations 'out
17 there' which rely on the mixin naming conventions, at least I
18 cleaned out all cross-class name usage. So once we are OK with
19 breaking compatibility, the two systems can be separated.
20
21 * IPython/Logger.py: major cleanup. This one is NOT a mixin
22 anymore, and the class is a fair bit less hideous as well. New
23 features were also introduced: timestamping of input, and logging
24 of output results. These are user-visible with the -t and -o
25 options to %logstart. Closes
26 http://www.scipy.net/roundup/ipython/issue11 and a request by
27 William Stein (SAGE developer - http://modular.ucsd.edu/sage).
