Voilà template for Materials Cloud

This is the Voilà template for Materials Cloud, implements the standard header and CSS.

Three templates are provided:

• materialscloud-tool - highlights the WORK/Tools section in the header/breadcrumbs.
• materialscloud-discover - highlights the DISCOVER section in the header/breadcrumbs.
• materialscloud-iframe - just adds a simple "Hosted on Materials Cloud" note at the bottom.

Installation

pip install voila-materialscloud-template

This installs the templates in the correct Jupyter path (using copy_voila_template.py).

Usage

The main way is to use the voila --template option, e.g.:

voila --template=materialscloud-tool example.ipynb

Alternatively, you can write a voila.json file containing

{
  "VoilaConfiguration": {
    "template": "materialscloud-tool"
  },
  ...
}

and passing its path with

voila --Voila.config_file_paths=<...> example.ipynb

There are also other options, see the Voilà documentation for more information.

Development

Option 1:

pip install -e .[dev]

Note: this will copy the templates to the jupyter folder, and they need to be modified directly there or re-copied for changes to take effect.

Option 2:

It's more convenient to use a docker container and rebuild after modification:

cd docker
docker compose up --build

and access via http://localhost:8866/. The template and other voila configuration is specified in voila.json.

Note: maybe there is an easier setup, e.g. with live-reload or similar.

Making a new release

To release a new version, just make a new release on Github with the correct version tag, without updating any versions manually. This will start the GitHub action that will

• update version numbers in the repo and commits it;
• tags this new commit with the version, overwriting the tag that was made by the Github release;
• pushes commit & tag to Github;
• publishes new version on PYPI.
