This is an implementation of #1093. Usage example is in this notebook

I'm not sure the comment here match the regex below.

[mgaitan]

you are right. a careless copy&paste. fixing.

[Carreau]

I'm wondering wether there is some code that could be share/factored from
extract_hist_ranges in IPython/core/history.py, the behavior might be slighty different or to painfull to share code.

Just wondering.

[mgaitan]

Thanks @Carreau . as I thought the same thing I decided implement an independent extract_code_ranges and don't touch history.py .

Nice addition... and looks good.

[Carreau]

+1 too.

Looks like you have an editor configured to strip whitespace in blocks you are not actually editing. Can you rebase without these unhelpful changes?

[minrk]

Looks good to me, after rebasing without the large whitespace changes. This is fairly straightforward with:

alias git-rebase-nows='git rebase -i --exec="git format-patch -w HEAD^1 --stdout | sh -c \"git reset HEAD^1 --hard; git am -\""'
git-rebase-nows origin/master

[mgaitan]

@minrk the alias trick didn't work for me. (I got error: unknown optionexec=git format-patch -w HEAD^1 --stdout | sh -c "git reset HEAD^1 --hard; git am -"'`). I've forced the branch applying my last commit against master HEAD ignore whitespaces

$ git diff HEAD 4ef59c262 --ignore-space-at-eol > patch
$ git apply --ignore-whitespace patch

hope this would be ok. I'll config the editor/git to avoid this unhelpful changes.

[damianavila]

Great! Much cleaner now...

[mgaitan]

Please, could you review mgaitan/ipython@d4d4726 . I feel more comfortable with python than with english :)

Sorry if my example didn't work for you, may be a git version issue, or maybe I pasted it wrong. Anyway, thanks for your patience, merging now.
