Docs: https://developers.google.com/blockly/guides/overview Repo: https://github.com/google/blockly ## Requirements - JupyterLab >= 4.0.0 ## Install To install the extension, execute: ```bash conda install -c conda-forge jupyterlab-blockly ``` or ```bash pip install jupyterlab-blockly ``` #### Kernels - ipykernel - xeus-python - xeus-lua - [JavaScript](https://github.com/n-riesco/ijavascript#installation) - [JavaScript](https://github.com/yunabe/tslab) ## Uninstall To remove the extension, execute: ```bash conda uninstall -c conda-forge jupyterlab-blockly ``` or ```bash pip install jupyterlab-blockly ``` ## Contributing ### Development install Note: You will need NodeJS to build the extension package. The `jlpm` command is JupyterLab's pinned version of [yarn](https://yarnpkg.com/) that is installed with JupyterLab. You may use `yarn` or `npm` in lieu of `jlpm` below. ```bash micromamba create -n blockly -c conda-forge python nodejs=18 pre-commit jupyterlab jupyter-packaging jupyterlab-language-pack-es-ES jupyterlab-language-pack-fr-FR ipykernel xeus-python xeus-lua micromamba activate blockly # Clone the repo to your local environment # Change directory to the jupyterlab_blockly directory # Installing pre-commit to run command when adding commits pre-commit install # Install package in development mode pip install -e ".[dev]" # Link your development version of the extension with JupyterLab jupyter labextension develop . --overwrite # Rebuild extension Typescript source after making changes jlpm build ``` You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the extension. ```bash # Watch the source directory in one terminal, automatically rebuilding when needed jlpm watch # Run JupyterLab in another terminal jupyter lab ``` With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt). By default, the `jlpm build` command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command: ```bash jupyter lab build --minimize=False ``` ### Development uninstall ```bash pip uninstall jupyterlab_blockly ``` In development mode, you will also need to remove the symlink created by `jupyter labextension develop` command. To find its location, you can run `jupyter labextension list` to figure out where the `labextensions` folder is located. Then you can remove the symlink named `jupyterlab-blockly` within that folder. ### Packaging the extension See [RELEASE](RELEASE.md) --- _Source: https://npm.io/package/jupyterlab-blockly · Machine-readable twin of the npm.io package page.
