[IPython-dev] Interactive input block handling

[Fernando Perez]

Hi folks,

here:

http://github.com/fperez/ipython/commit/37182fcaaa893488c4655cd37049bb71b1f9152a

is the code that Evan can start using now (and so can Omar as we
refactor the terminal code) for properly handling incremental
interactive input.  I ran out of time to add the block-splitting
capabilities for Gerardo, but that should be easy tomorrow.

It would be a good habit to get into for all new code, to attempt as
best as possible 100% test coverage:

(blockbreaker)amirbar[core]> nosetests -vvs --with-coverage
--cover-package=IPython.core.blockbreaker blockbreaker.py
test_dedent (IPython.core.blockbreaker.BlockBreakerTestCase) ... ok
test_indent (IPython.core.blockbreaker.BlockBreakerTestCase) ... ok

OK

In this case it actually helped me a lot, because in going from ~85%
to 100% I actually found that the untested codepaths were indeed
buggy.  As the saying goes, 'untested code is broken code'...
