VS Code tasks.json Generator

The VS Code tasks file lets you run project commands from the editor, with a shortcut and with the output captured. The real value is not saving a trip to the terminal — it is the problem matcher, which reads the output, recognises error messages and turns them into markers in the code and entries in the problems list.

Fill in the label, the type, the command and the group, and the page assembles the JSON with the correct schema version. The group is what makes the task appear under the run build or run test commands, and marking it as the group default is what allows firing it straight from the shortcut, without picking from a list.

The problem matcher field deserves attention. Leaving it empty makes the editor ask every time how to interpret the output, which gets tiring fast. Several matchers ship built in, and extensions add their own. When none fits, you can declare one with your own regular expression — and when the output has no errors to recognise, the right move is declaring an explicitly empty list so the editor stops asking.
