Development Environment Setup

It is recommended to use a virtual environment to setup the development environment for iBeatles. The following instructions are for setting up a virtual development environment using pixi. For detailed instructions on how to install pixi, please refer to the pixi documentation.

• Install pixi:

curl -fsSL https://pixi.sh/install.sh | bash

• Clone the iBeatles repository:

git clone [e-mail]:ornlneutronimaging/iBeatles.git

• Install the dependencies:

cd iBeatles
pixi install

Note that pixi install will install all dependencies, including the editable version of iBeatles.

By default, pixi is configured to use detached-environments so that you can build the conda packages directly in the repo. This settings can be changed by pixi config set detached-environments false if needed.

Run iBeatles

There are several ways to start the application:

• Use the entry script to start the GUI application.

pixi run ibeatles

• Use pixi tasks run to start the GUI application.

# to start GUI application
pixi run start
# to start CLI application
pixi run cli  <CONFIG_FILE>

• Use Python interpreter to start the GUI application.

# start GUI application
pixi run python -m ibeatles
# start CLI application
pixi run python -m ibeatles --no-gui <CONFIG_FILE>

Run Tests

To run the tests, use the following command:

pixi run test

Alternatively, you can always invoke the Python interpreter directly:

python -m pytest

Note: we recommend using pixi to run the tests as it will ensure that the correct environment is used.
