Development

This project uses Hatch for managing the development environment.

Prerequisites

Install xvfb for running the snapshot tests.

TODO: some more effort might be necessary to support Windows and macOS.

Run all tests

hatch test --all
hatch run test-minimal:run
hatch run test-snapshot:run

Create environment for IntelliJ

Create a development environment in .venv/ which can easily be used by IntelliJ or other IDEs:

hatch env create dev

Run development version

hatch shell
clipboard-processor

or

hatch run clipboard-processor

Troubleshooting

In case dependencies are not synced into an existing env, try removing all environments:

hatch env prune
