Plotly introduces errors with magic syntax highlighting in Jupyter

[msftristew]

It looks like the init_notebook_mode() function introduces some conflicts with Jupyter that causes magics syntax highlighting in IPython to not work correctly. The issue is that Plotly seems to conflict with the mechanism that Jupyter uses for magics syntax highlighting.

Repro steps:

1. Make a simple IPython wrapper kernel and configure it to use syntax highlighting for a non-Python language in a cell with a particular cell magic, e.g. SQL syntax highlighting after the %%sql magic
2. Run init_notebook_mode in a cell
3. Try to run a cell with the %%sql magic; syntax highlighting will not work and errors will be logged to the JS console

Here are some screenshots for my machine. Syntax highlighting gets turned off after I run init_notebook_mode:

When I type %%sql in the cell, these errors get logged:

... so it looks like the call to init_notebook_mode is interfering with Jupyter's require.js machinery in some way.

I am wondering if this issue is related to issue 90 or if it happens to have been solved in this commit.

Hi @msftristew the commit you referenced should fix it, and that commit has been merged into plotly master

Thanks @jdfreder. When will the next version of plotly be released that will have this fix?

Hello, I am new to Jupyter as of this week and ran into the same error message. What does "ERROR: Cell magic 'sql' not found." indicate? This syntax based on previous inputs should work:

%%sql
SELECT start_time AS "exam start time"
FROM exam_answers;

Any ideas?

In my screenshot, the %%sql magic doesn't actually exist, I'm just using it as an example to show how this function breaks syntax highlighting.

Ping :)

Is there an ETA on the new version which will fix this?

Should work now!

It does! Thank you.
