@rafelyall/celltag2dom v0.1.1

celltag2dom

Transfer cell tag metadata to JupyterLab notebook HTML.

Usage

Adds two new commands, dom-tags-on and dom-tags-off (default keymappings Ctrl-Y and Ctrl-Shift-Y), which will add/remove classes to JupyterLab cell HTML elements based on celltag metadata. Cell tags must be prefixed with dom-, where the suffix will be used as the class ID: dom-myclass. This can be used to add custom styling to specific cells (code or markdown) based on the presence of cell tags, for example using the custom-css JupyterLab extension.

Alterations to notebook HTML are not persistent if the notebooks are closed and re-opened.

Requirements

• JupyterLab >= 2.0

Install

jupyter labextension install @rafelyall/celltag2dom

Contributing

Install

The jlpm command is JupyterLab's pinned version of yarn that is installed with JupyterLab. You may use yarn or npm in lieu of jlpm below.

# Clone the repo to your local environment
# Move to celltag2dom directory

# Install dependencies
jlpm
# Build Typescript source
jlpm build
# Link your development version of the extension with JupyterLab
jupyter labextension install .
# Rebuild Typescript source after making changes
jlpm build
# Rebuild JupyterLab after making any changes
jupyter lab build

You can watch the source directory and run JupyterLab in watch mode to watch for changes in the extension's source and automatically rebuild the extension and application.

# Watch the source directory in another terminal tab
jlpm watch
# Run jupyterlab in watch mode in one terminal tab
jupyter lab --watch

Now every change will be built locally and bundled into JupyterLab. Be sure to refresh your browser page after saving file changes to reload the extension (note: you'll need to wait for webpack to finish, which can take 10s+ at times).

Uninstall

jupyter labextension uninstall @rafelyall/celltag2dom
