Extended Jupyter Cell Tags support in VS Code

This extension provides extended support for notebook cell tags and cell run groups in Visual Studio Code.

I needed more functionality and was tired of fussing with the Jupter/VSCode/Powertoys version hell, so I forked the repo implemented it myself. My pull request on the official repo is here: https://github.com/microsoft/vscode-jupyter-cell-tags/pull/40, but there seems to be no progress on merging it.

After this, I added custom run groups to work around https://github.com/microsoft/vscode-jupyter-powertoys/issues/90 and believe I improved the expierence (at least for myself) over the Jupyter Powertoys version, as it allows an arbitrary number of run groups with custom names.

This fork is available on marketplace here:

Name: Pho Jupyter Cell Tags
Id: phohale.pho-vscode-jupyter-cell-tags
Description: Extended Jupyter Cell Tags support for VS Code
Version: 0.3.6
Publisher: PhoHale
VS Marketplace Link: https://marketplace.visualstudio.com/items?itemName=PhoHale.pho-vscode-jupyter-cell-tags

or via github https://github.com/CommanderPho/vscode-jupyter-cell-tags here

Features:

Add a tag to the cell you're on by opening the Command Palette (Cmd+Shift+P) and selecting Add Cell Tag or by clicking + Tag on the cell
Add multiple tags to the cell you're on by opening the Command Palette (Cmd+Shift+P) and selecting Jupyter: Focus on Cell Tags View and clicking on +
Modify tags in the notebook's metadata (JSON format) by opening the Command Palette (Cmd+Shift+P) and selecting Edit Cell Tags (JSON) or by clicking out to it from the Cell Tags View
Cell Run Groups allow you to execute all cells with a given tag. You can select tags to run from the menu Excecute Tag Run Group or via the similarily named command. Tags that start with the "run-" prefix will appear first in the run list.
More undocumented commands available in the menus, documentation coming soon.

This extension replaces the forked extension that comes with the Jupyter extension for Visual Studio Code. You must first uninstall the official Microsoft version before installing this one.

2025-02-25 - on macOS, I had to remove `nodenv` from path (an alternative to `nvm` for managing node versions) and move `nvm` up onto path. Also ahve to run with `zsh` instead of `bash`.

2025-02-26 - IMPORTANT - Finally got extension debugging working reliably

https://vscode.dev/editor/profile/github/62d11f2ed58b3e59527093d8318c1847

In .vscode\launch.json, I had to add a fixed extension debugging profile: "--profile=PhoExtensionDev2025",

		{
			"name": "Run Extension",
			"type": "extensionHost",
			"request": "launch",
			"args": [
                // "--profile-temp",
				"--profile=PhoExtensionDev2025",
				"--extensionDevelopmentPath=${workspaceFolder}",
                // "--disable-extensions",
                "--enable-proposed-api",
                "phohale.jupyter"
			],
			"outFiles": [
				"${workspaceFolder}/out/**/*.js"
			],
			"preLaunchTask": "${defaultBuildTask}",
		},
