Recently the project jupyter added the mime-type to the ipynb files: application/x-ipynb+json, and I'd like to launch easily these files without having to allways launch the terminal command:

cd /path/to/notebook
jupyter notebook

So I've adapted this blog post in order to:

  • launch a jupyter-notebook server when double clicking a ipynb file
  • add icon to ipynb files.
  • create a desktop Launcher to easily launch a jupyter notebook from a default folder or dragging and dropping a file or folder.

Here's how it looks, and see my answer below to understand how to do this.

1. Create a ipynb.xml mime-info file

<mime-info xmlns='http://www.freedesktop.org/standards/shared-mime-info'>
    <mime-type type="application/x-ipynb+json">
        <comment>IPython Notebook</comment>
        <glob pattern="*.ipynb"/> 
    </mime-type>
</mime-info>

Then store the file in ~/.local/share/mime and update the mime database.

cp ipynb.xml ~/.local/share/mime
update-mime-database ~/.local/share/mime

2. Create a jupyter.desktop file

Caution: Edit paths to adapt it to your system and habits.

[Desktop Entry]
Version=1.0
Type=Application
Name=Jupyter
Icon="$HOME/.icons/jupyter-sq-text.svg"
Exec=/path/to/jupyter notebook %F
Path="$HOME/Documents/Notebooks"
Comment=Jupyter notebook
MimeType=application/x-ipynb+json;
Categories=Science;
Terminal=true

Then install the desktop file:

desktop-file-install --dir="$HOME/.local/share/applications"  jupyter.desktop

3. Add the jupyter icon

I chose the svg version from the design repository of jupyter, and installed in ~/.local/share/icons

wget https://raw.githubusercontent.com/jupyter/design/master/logo/svg/jupyter-sq-text.svg -o $HOME/.local/share/icons/jupyter-sq-text.svg

Finally, link the mime-type icon to the system:

sudo ln -s $HOME/.local/share/icons/jupyter-sq-text.svg /usr/share/icons/gnome/scalable/mimetypes/application-x-ipynb+json.svg
sudo gtk-update-icon-cache /usr/share/icons/gnome/ -f

Hope that's help!
