And clean up some logic in `rule.py`. This is the place where the
"brains" of Copycat really live, it seems; Copycat can only succeed
at solving a puzzle if it can take the `Rule` it deduced and apply
it to the target string to produce a new string. And it can only
do that if the necessary *actions* have been programmed into `rule.py`.
Right now, it explicitly can't deal with "rules" that involve more
than one local change; that involve reversal; or more importantly,
IIUC, rules that involve "ascending runs", because the idea of a
successor-group is(?) known to the Slipnet but not to `rule.py`;
the latter deals only in "strings", not in "workspace objects".
This seems like a major flaw in the system... but maybe I'm missing
something.
You can now install Copycat into your Python virtualenv without even
checking out this repository! Just run this command:
pip install -e git+git://github.com/Quuxplusone/co.py.cat.git#egg=copycat
To check out a specific branch,
pip install -e git+git://github.com/Quuxplusone/co.py.cat.git@branch#egg=copycat
