Hey Ben,
You can do this by invoking some Javascript to get the notebook name, and
then using Javascript to call Julia back again. It's kind of neat. First,
in Javascript, you can get this directly via:
IPython.notebook.notebook_name
You can pull up your browser's javascript console inside an IJulia notebook
to see that this works. Next, you can send commands to computation kernels
such as Julia and Python straight from Javascript, (Which of course, is the
foundation upon which the IJulia and IPython notebooks are built upon) so
let's set a Julia variable called notebook_name to be equal to the
Javascript variable above:
IPython.notebook.kernel.execute('notebook_name =
"'+IPython.notebook.notebook_name+'" ');
Again, you can paste that into your Javascript console to run it directly
as Javascript. After doing so, try printing the Julia variable called
notebook_name; it will have magically appeared in your workspace.
Finally, let's get Julia to output the Javascript instead of us, so we can
put it in a cell at the top of our file and have everything "just work":
display("text/html", """<script
charset="utf-8">IPython.notebook.kernel.execute('notebook_name =
"'+IPython.notebook.notebook_name+'" ');</script>""")
I realize it gets a little heady as a one-liner, so here's a notebook
<http://nbviewer.ipython.org/github/staticfloat/notebooks/blob/master/julia_notebooks/NotebookNameTest.ipynb>
showing it off in action.
