I tried to follow the instructions given in the README file of the extension. Im using Windows and to open my notebooks I use the jupyter-notebook.exe stored in the directory

..\Anaconda3\Scripts

Within the Anaconda3 directory I go to the subdirectory

Anaconda3\Lib\site-packages\jupyter_contrib_nbextensions\nbextensions\snippets

and there change the code of the file "snippets.json" from

{
"snippets" : [
    {
        "name" : "example",
        "code" : [
            "# This is an example snippet!",
            "# To create your own, add a new snippet block to the",
            "# snippets.json file in your jupyter data directory under nbextensions:",
            "# $(jupyter --data-dir)/nbextensions/snippets/snippets.json",
            "import this"
        ]
    }
]
}

to

{
    "snippets" : [
        {
            "name" : "example",
            "code" : [
                "# This is a test if something changed",
            ]
    ]
}

Then I restart my notebook and insert the example snippet. But my changes weren't adopted, I still get the original example snipped.

What I am doing wrong?

  • Be aware there are many files "snippets.json" and you need to find that one which the server uses. You have probably changed not the right file. Detailed answer: https://github.com/ipython-contrib/jupyter_contrib_nbextensions/issues/1279. For some users, the following path worked: C:\Programs\Anaconda3\share\jupyter\nbextensions\snippets – Ilias Machairas May 07 '20 at 20:38

If you are using Anaconda, you don't necessarily need to go searching for directories. There is a template embedded in the "Nbextensions" tab.

  • Check "Snippets Menu" box
  • Scroll down to 'Parameters' and check the "Include custom menu...JSON string below" box
  • Insert whatever sample snippet you want
  • Refresh your notebook

Check out one of my snippets:

{
    "name" : "My favorites",
    "sub-menu" : [
        {
            "name" : "import packages",
            "snippet" : ["# import various packages"
                   "import os"
                   "import scipy"
                   "import pandas as pd"
                   "import numpy as np"
                   "import seaborn as sns"
                   "import matplotlib.pyplot as plt"

                   "%matplotlib inline"

                   "# plot settings"
                   "from pandas.plotting import register_matplotlib_converters"
                   "register_matplotlib_converters()"
                   "plt.rcParams['agg.path.chunksize'] = 10000"]
        },
        {
            "name" : "TeX can be written in menu labels $\\alpha_W e\\int_0 \\mu \\epsilon$",
            "snippet" : ["another_new_command(2.78)"]
        }
    ]
}

Also, be careful with the quotations and commas. Additional help on that can be found here.

In windows(os) jupyter notebook extension are hidden in programData folder (C:\ProgramData\jupyter\nbextensions\snippets)

To make changes in snippet just edit the snippets.JSON file accordingly: enter image description here

I think you are searching in the wrong directory.

  • In windows, run command jupyter --paths in anaconda prompt this will return the locations of config: data: & runtime:
  • search for the file snippets.json in the data: locations
  • in my case it is C:\ProgramData\jupyter\nbextensions\snippets

change and save the content in snippets.json and then restart your jupyter notebook it will work!
