Merge pull request #1361 from ellisonbg/nbissues A number of bug fixes for notebook issues that had crept up recently with all the major improvements done on multiple fronts. In closing #1359, we've changed slightly how Math() works: it now unconditionally surrounds its input with $$...$$, so that it always appears in displayed math mode. We have also introduced a new display object, Latex(), which does *not* add any latex markup, for other constructs beyond simple math expressions. This change makes Math() friendlier to use in simple cases and means that Math(sympy.latex(foo)) will produce the expected displayed math results without the user having to add any $ markup. Summary of fixes: Fixes #1344: Ctrl + M + L does not toggle line numbering in htmlnotebook. Fixes #1337: Tab in the notebook after `(` should not indent, only give a tooltip. Fixes #1339: Notebook printing broken. Fixes #1348: `Ctrl-m-Ctrl-m` does not switch to markdown cell Fixes #1359: [sympyprinting] MathJax can't render \root{m}{n}

CodeMirror in IPython

We carry a mostly unmodified copy of CodeMirror. The current version we use is (please update this information when updating versions):

CodeMirror c813c94

The only changes we've applied so far are these:

     var doubleDelimiters = new RegExp("^((\\+=)|(\\-=)|(\\*=)|(%=)|(/=)|(&=)|(\\|=)|(\\^=))");

In practice it's just a one-line change, adding \? to singleOperators, surrounded by a comment. We'll turn this into a proper patchset if it ever gets more complicated than this, but for now this note should be enough.
