It works on Windows 10/Anaconda(version=2019.10).

I've tried on AWS/Linux EC2, there was an issue.
Tested in two cases: on JupyterHub and on Jupyter notebok - the same result!
One point, I did it when JupyterHub and Jupyter was runnning, after failed I stooped and tried again - the same result!

Can this integration be used with a private github URL instead of the actual github.com? In other words, can the URL be configurable (leaving the default to github.com)?

Expected behaviour

If I open some-notebook.ipynb in /home/jovyan/some-folder from the Files tab, the working directory for the kernel will be /home/jovyan/some-folder.

Unexpected behaviour

If I open some-notebook.ipynb while browsing using the GitHub tab, it seems like the working directory for the kernel will always be /home/jovyan.

As it says in the title, I think this could be a useful feature?

I'm not 100% sold on the idea myself but thought I'd put it out there to see if it garners any support...

Files with spaces in their names need to be escaped, otherwise they fail to load.

Followed the instructions in the README. "jupyter labextension list" command shows github is disabled. Tried enabling with "jupyter serverextension enable --py jupyterlab_github". No luck. Any help would be appreciated.

Hi,
great plugin - thanks!

We would like to have a tab in our jupyterhub/jupyterlab setup, which directs users to example notebooks prepared especially for our clusters.

Therefore I would like to use your plugin with our own gitlab server.
How difficult do you think would it be to make this possible?

Best,
Jens

Hello,

we would like to use your jupyterlab-github extension in a multiuser jupyterhub installation on our cluster, which shows users example notebooks (same purpose as explained in #43).

Is it possible to set a default github repository at installation time for all users
which is linked to the Home-button instead of an ?

Best,
Jens Henrik

Using lab themes, the github logo can sometimes be hard to make out against the background. If possible, it would be better to use an SVG logo styled with CSS (https://css-tricks.com/cascading-svg-fill-color/).

PS: This also holds for the google drive logo in the driver extension.

On April 7th, 2020 at 19:31 (UTC) you used a password to access an endpoint through the GitHub API using python-requests/2.18.4:

I did not access my account on that specific hour . I even forgot about this website. How come i get such notice if I don’t use the account???

Currently we are only showing the repository default branch. It would be nice to be able to switch branches.

Maybe a div on the filebrowser that explains it.

I have done step by step according to this code file, installed labextension and got my personal access token from Github.
While in the step 3. after installing jupyter_github, generating a configuration file named jupyter_notebook_config.py in my directory and run this file, when I type in c.GitHubConfig.access_token = '< ACCESS_TOKEN >', it returned an error message.

Code:
PS C:\Users\Username.jupyter> jupyter labextension install @jupyterlab/github

PS C:\Users\Username.jupyter> pip install jupyterlab_github
PS C:\Users\Username.jupyter> jupyter serverextension enable --sys-prefix jupyterlab_github

Then generated jupyter_notebook_config.py in the directory of PS C:\Users\Username.jupyter

PS C:\Users\Username.jupyter> c.GitHubConfig.access_token = '< YOUR_ACCESS_TOKEN >'

Error Return:
c.GithubConfig.access_token : The term 'c.GitHubConfig.access_token' is not recognised as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name. or if a path was included, verify that the path is correct and try again.

Thank you!!!

Perhaps overlay a div on the filebrowser explaining the rate-limiting, with a time that the rate-limiting will be lifted.

One can get 403 errors from being rate-limited and from trying to open files larger than 1Mb. We need to properly distinguish those cases.

Using J-Lab in Safari with this plugin, i put a username and it does not show the available repos.
I verified via Chrome, that the plugin was installed successfully, as things work there.

Here's what the javascript console says:

Hi!
First, thanks for your software!
I used it today to browse the public repos of a github user and subsequently received this deprecation notice in my email:

On February 5th, 2020 at 23:32 (UTC) your personal access token using JupyterLab GitHub was used as part of a query parameter to access an endpoint through the GitHub API:
https://api.github.com/
Please use the Authorization HTTP header instead, as using the access_token query parameter is deprecated.
Depending on your API usage, we'll be sending you this email reminder once every 3 days for each token and User-Agent used in API calls made on your behalf.
Just one URL that was accessed with a token and User-Agent combination will be listed in the email reminder, not all.
Visit https://developer.github.com/changes/2019-11-05-deprecated-passwords-and-authorizations-api/#authenticating-using-query-parameters for more information.
Thanks,

I'm using jupyterlab-github 1.0.0 and jupyterlab 1.2.6.

I installed Jupyter lab in developer mode(version=1.0.0a1). and tried to install jupyterlab-github from extensions manager in jupyter lab. It is causing the following compatibility errors.:
**An error occurred installing @jupyterlab/github.

Hi @ian-r-rose,

What an amazing work ❤️

Would you consider updating the version in package.json for this extension to work with the current Jupyter labextension 0.12.0+ version? I currently have this error (JPLab 0.29.1) when trying to install the labextension:

Currently extension supports browsing the repo and opening the current repo either in binder or github itself. It would be useful to be able to clone the repo in current working directory or user defined directory.

In version 2.1.2 I can't find "Copy" item in the context menu of the Files Browser as it is shown in the documentation on the picture. "Cut" item is available though.

Is it possible that my installation is somehow misconfigured or it is a bug?

My config:

c.NotebookApp.ip = '0.0.0.0'
c.NotebookApp.port = 8888
c.NotebookApp.notebook_dir = '/app/home'
c.NotebookApp.password = 'sha1:salt:hash'
c.NotebookApp.open_browser = False
c.NotebookApp.allow_password_change = False
c.NotebookApp.allow_root = True

The app is launched as jupyter lab.

https://developer.github.com/enterprise/2.13/v3/#oauth2-token-sent-as-a-parameter

In trying to get this extention working with GHE (#34) access tokens appear to work when making api requests whereas the client_id/client-secret returns an unauthorized error:

{
  "message": "Must authenticate to access this API.",
  "documentation_url": "https://developer.github.com/enterprise/2.11/v3"
}

Hello,

thanks for the great extension. It plays an important role for our cluster-wide installation of JupyterHub/JupyterLab and allows users to browse example notebooks easily.

These example notebooks often include links to other notebooks in the same github repository in Markdown cells like this:

* [Notebook Basics](examples/Notebook/Notebook Basics.ipynb)
* [IPython - beyond plain python](examples/IPython Kernel/Beyond Plain Python.ipynb)
* [Markdown Cells](examples/Notebook/Working With Markdown Cells.ipynb)

This will lead to a generated but wrong/damaged link like this:
github:<notebook-path-on-github>/<relative-path-to-file>

This is also relevant, if notebooks refer to images, which are part of the repository.

Best,
Jens Henrik

Description

Hello, I am new to Python and I decided to use your environment.
An error appear when I try to install extensions.

"jupyter labextension install @jupyterlab/github"
"jupyter lab build"

I get the error :
jupyterLab failed to build

The log file shows an issue finding the module './_baseValues'
Error: Cannot find module './_baseValues'

I have not been able to find a solution.

I tried using
npm install ../_baseValues

This is really a great addition to Jupyterlab. I'm wondering if anyone has devised a way of setting the token in Jupyterhub (and specificity using the Zero to Jupyterhub helm chart)? Thanks in advance.

Hi,

I'm having an issue with Git submodules as described below:

Description

When a directory is a GIT submodule, an attempt to open it with the @jupyterlab/github extension
displays an error:

Reproduce

1. Create a GIT submodule on the file system typing something like this on the
   command line

# To add and clone a new submodule
$ git submodule add https://github.com/chaconinc/DbConnector
$ git clone https://github.com/chaconinc/MainProject
$ git submodule init
$ git submodule update

2. Open Jupyter Lab with the @jupyterlab/github extension installed.
3. Open the GIT panels and browse to the submodule
4. See error 'Cannot open <directory> because it is a submodule'

Expected behavior

Git submodules should be supported like regular Git modules. That would be extremely helpful!

Context

• Python package version:

  # packages in environment at c:\Miniconda:
  #
  # Name                Version               Build  Channel
  jupyterlab-github    1.0.0                 pypi_0    pypi
  

Thanks,

WetHat

There is a wrong text encoding if you try to open any file with non-english characters like russian or japanese. You can see that in README.md for github-repository on russian here: Skaarj7/netology or on japanese: gogotanaka/Primes. Just trash instead of cyrillic symbols or hieroglyphs.

I had this running fine for a while, but since a few weeks ago, I'm getting this error in my server log, despite the fact that browsing user's GitHub repos actually works?

/Users/klay6683/miniconda3/envs/py37/lib/python3.7/site-packages/traitlets/config/configurable.py:84: UserWarning: Config option `client_id` not recognized by `GitHubConfig`.

  self.config = config

I have an OAuth configured and have c.GitHubConfig.client_id and c.GitHubConfig.client_secret defined in jupyter_notebook_config.py.

My Jlab version is 1.1.4 and I have updated to the latest jupyterlab-github via the Jlab extension manager plugin.

This seems to be fixed in #48 but not for me...

I have access to all private repositories in an organization. I have created an access token (for my user, not for the organization) with full repo permissions and added it to jupyter as described in your README:

~:: cat ~/.jupyter/jupyter_notebook_config.py 
c.GitHubConfig.access_token = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

Still only public repos are listed for the organization in jupyterlab.

I'm running this extension successfully in a py36 conda env, with this minor hiccup that the tab name is blank:

My installed jupyter related versions are:

Some people have their config py files on their repo and use such files in their notebook, but this extension cannot import such py files. It will throw a ModuleNotFoundError.

At the very least, show an error if a user tries to open one.

We should detect if the server proxy is not installed and use the extension purely client-side (with a warning). Then the user could get a few minutes of use before being rate limited.

@ian-r-rose @dhirschfeld
We're building a similar plugin for GitLab and had a couple of questions about design choices you made in this repo. We would be grateful if you could answer some of these as it'll set us on the right path.

• I see that you are fetching repository contents via GitHub API and converting them into Jupyter models (Contents.IModel etc.). Why not simply run a git clone from the server extension? That way the contents would be available under the regular file browser of Jupyter

• Are the repository contents backed on disk somewhere? Does the refresh from repo overwrite the local edits?

• I'm wondering if we were to go git clone way, how hard/easy would it be to later support 2-way synch (commit/push to repo etc.). Maybe we could read the repository state on disk and allow users to do git add/commit/push etc. Maybe use the git extension on the top.

Feel free to mention anything else I should be aware of. Thanks for your time!

after i installed this github extension，filelists in the filebrowser disappeared。i've googled and tried a lot，but can't fix it ，finally had to reinstall jupyterlab and delete all the node_modules@jupyterlab . it returned to normal, i guess sth is not compatible with filebrowser.

To be something more specific/recognisable.

https://github.com/jupyterlab/jupyterlab-github/blob/master/schema/drive.json

I'd suggest github.json would better reflect the contents of the file.

Typing in my username in the username field, I only gets the first 30 repositories. This is irrespective of sorting order.

Edit: If I type in minrk, I only get to repo names starting with 'b' before being cut off ;)

For content from github, it really does not need refresh every 10 seconds.

As we have more than 1000 repos in an org, the list always changed back to repos of org even user enter a repo because the request of repos in org is longer than 10 sec.

I'm trying to view private repos for my org. I'm running JupyterHub in minikube with JupyterLab configured. I've also installed both the lab as well as server extensions by adding the following to my userimage dockerfile

RUN jupyter labextension install @jupyterlab/github

RUN pip install jupyterlab_github
RUN jupyter serverextension enable --sys-prefix jupyterlab_github

I've confirmed that the python package version is 0.6 and I am running jupyterlab version 0.32.0.

I've added my access token to helm values file as:

hub:
  extraEnv:
    JUPYTER_ENABLE_LAB: 1
  extraConfig: |
    c.KubeSpawner.cmd = ['jupyter-labhub']
    c.GitHubConfig.access_token = 'XXXXXXXXXXXXXXXXXXXXXXXX'

I cannot see any of the private repos.

I'm also seeing sporadic rate-limiting which makes me believe that possibly the server extension is not properly installed?

Any guidance would be appreciated.

Hi all,
I'm trying to pre-load the default github repo that is shown when a docker is loaded up using the something like the following in my dockerfile (and needless to say, not working):

#Set up github access (this is temporary; real version will request key at container runtime)
RUN echo "c.GitHubConfig.access_token = 'ToBeReplacedWithLineInRunTimeShellScript'" >> ~/.jupyter/jupyter_notebook_config.py

RUN mkdir -p ~/.jupyter/lab/user-settings/@jupyterlab/github && \

The extension is really nice to run a notebook directly from a GitHub repository.

I think a common use case is to create a local copy of a notebook so that it can be modified and saved locally. I can't find an easy way to copy a file from the GitHub drive to the local filesystem.

I tried to use "Copy" from the contextual menu (when right clicking on a file) and then "Paste" but nothing happens.

The only way I found so far is to open the notebook in a text editor, copy the content, create a text file, paste, and rename the file. Not super user friendly. Is there a better way to do that?

It would be nice if you could hook this extension up to GHE!

It seems this could perhaps be done by simply making GITHUB_API (and possibly GITHUB_BASE_URL) configurable:

This will give resources on GitHub a unique path from JupyterLab's perspective, and will allow, among other things, page refresh to work correctly.

@ian-r-rose ... was trying to install this via a Dockerfile, but hitting this error. Is the plan to post this as a package to npmjs.org? Thanks.

is this extension working??

Hi All,

I have installed the jupyterlab-github client and serverside extension as per the instructions in the ReadMe. The application is working great, but I am not able to access (or even view) my private repositories. Is private repository access currently supported, or in the works (hopefully)?

Thanks!

The github extension cannot show up on Microsoft Edge browser (but it works fine on Chrome).

When I try to open a notebook using the extension, I always get the error:

File Load Error for ....
undefined is not an object (evaluating 'value.cells')

If I download the file locally, I have no issue opening it.
I'm using (installed from conda-forge):

  - jupyter_client=5.2.3=py_1
  - jupyter_core=4.4.0=py_0
  - jupyterlab=0.35.4=py36_0
  - jupyterlab_server=0.2.0=py_0
  - notebook=5.7.2=py36_1000
  - pip:
    - jupyterlab-github==0.7.0

lab extension:
@jupyterlab/github v0.10.0  enabled  OK

Our GHE can be connect directly from browser. So if GITHUB_API is configurable, then we do not need server side proxy.
