Test helper

This is a small VS Code extension that helps with managing Typst's test suite. When installed, for all .typ files in the tests directory, the following Code Lens buttons will appear above every test's name:

View: Opens the output and reference image of a test to the side.
Run: Runs the test and shows the results to the side.
Save: Runs the test with --update to save the reference output.
Terminal: Runs the test in the integrated terminal.

In the side panel opened by the Code Lens buttons, there are a few menu buttons at the top right:

Refresh: Reloads the panel to reflect changes to the images.
Run: Runs the test and shows the results.
Save: Runs the test with --update to save the reference output.

Installation

In order for VS Code to run the extension with its built-in Node engine, you need to first build it from source. Navigate to test-helper directory and build the extension:

bash

npm install    # Install the dependencies.
npm run build  # Build the extension from source.

Then, you can easily install it (and keep it up-to-date) via VS Code's UI:

Go to View > Command Palette or press Cmd/Ctrl+P,
In the drop down list, pick command "Developer: Install Extension from Location",
Select this test-helper directory in the file explorer dialogue box. VS Code will add the extension's path to ~/.vscode/extensions/extensions.json (or %USERPROFILE%\.vscode\extensions\extensions.json on Windows).
