Binder and Cocalc are tools for deploying Jupyter notebooks, R/shiny notebooks and Pluto notebooks. These binding tools do a lot more and do not leverage GNU Guix lightweight container infrastructure. In this project we want to create a binding-lite.
Key is to leverage what is in Guix and what we already have in GeneNetwork as much as possible.
We should create this separately from genenetwork because all we want to do is run notebooks in containers. We should be able to use and external authentication system, fetch notebooks from git elsewhere and push them on git elsewhere.
binding-lite will be packaged in GNU Guix. GeneNetwork will essentially be a 'rebranding' of binding-lite.
Later we'll add an API to create notebooks on the fly. That is a separate topic.
The current way of using guix-jupyter is to create a guix environment that contains the guix-jupyter kernel and jupyter.
The user can then run the `jupyter notebook` command which prints a url to the terminal for the user to copy/paste into the browser.
Once the url is opened in the browser, a user has to select the guix kernel and choose the notebook from the file manager menu.
The first goal is to fire up a jupyter notebook from a local git repository.
Afterwards, this would be implemented with a remote git repository.
We need a command line interface/tool and guile library to automate the process of opening a jupyter notebook from a local git repository.
Some of the tasks that `guix-notebook-launcher` will need to automate is preselecting the guix kernel and opening the browser to the notebook view
of the given url.
Here is an example of how the command line interface would be used:
$ guix-notebook-launcher file:///path/to/<git-repository>
To access the notebook, open this file in a browser:
file:///path/to/<git-repository>
or copy and paste one of these URLs:
http://localhost:8890/?token=fc21c17b9ec31eddbea28c06ce086cf71b5605a09610439b
or http://127.0.0.1:8890/?token=fc21c17b9ec31eddbea28c06ce086cf71b5605a09610439b
We'll need a manifest.scm file that will specify the dependencies needed by the guix-jupyter notebook.
Below is an example of the contents of a guix-jupyter notebook repository that can be given to `guix-notebook-launcher`:
$ tree <git-repository> . ├── LICENSE ├── README.md ├── index.ipynb └── manifest.scm
An example of the contents of manifest.scm:
(specifications->manifest
'("python-numpy"
"python-pandas"
"python-matplotlib"))
One possibility for easing the creation of a manifest.scm in the notebook repository is to parse the requirements.txt/setup.py,
in the case of a python notebook, and generate the manifest.scm file for the notebook user.
We would have to write similar manifest generators for Julia and R project dependencies in order to support this feature.
I will ask on the guix mailing lists for feedback on this idea.
Once we have this library we can start building binder-lite on top of it.
The use cases for `guix-notebook-launcher` are driven by the following design decisions:
`guix-notebook-launcher`, by users on their workstations.
Current Notebook Container Default Settings
Yes
A manifest! Which of course is just another record :)
scheme@(guix-user)> ,use (gnu packages) (guix profiles)
scheme@(guix-user)> (manifest? (specifications->manifest '("python-ipython")))

Should binder-lite be a distribution of GNU Guix System?
GeneNetwork can provide custom ISO and QEMU images that contain binder-lite ready to be deployed to bare metal or a VM.
This is inspired by the-littlest-jupyterhub distribution.
