This is a minimal template repository for _ChRIS_ plugin applications in Python.

## About _ChRIS_ Plugins

A _ChRIS_ plugin is a scientific data-processing software which can run anywhere all-the-same:
in the cloud via a [web app](https://github.com/FNNDSC/ChRIS_ui/), or on your own laptop
from the terminal. They are easy to build and easy to understand: most simply, a
_ChRIS_ plugin is a command-line program which processes data from an input directory
and creates data to an output directory with the usage
`commandname [options...] inputdir/ outputdir/`.

For more information, visit our website https://chrisproject.org

## How to Use This Template

Go to https://github.com/FNNDSC/python-chrisapp-template and click "Use this template".
The newly created repository is ready to use right away.

A script `bootstrap.sh` is provided to help fill in and rename values for your new project.
It is optional to use.

1. Edit the variables in `bootstrap.sh`
2. Run `./bootstrap.sh`
3. Follow the instructions it will print out

## Example Plugins

Here are some good, complete examples of _ChRIS_ plugins created from this template.

- https://github.com/FNNDSC/pl-dcm2niix (basic command wrapper example)
- <https://github.com/FNNDSC/pl-adapt_object_mesh> (parallelizes a command)
- https://github.com/FNNDSC/pl-mri-preview (uses [NiBabel](https://nipy.org/nibabel/))
- https://github.com/FNNDSC/pl-pyvista-volume (example using Python package project structure and pytest)
- https://github.com/FNNDSC/pl-fetal-cp-surface-extract (has a good README.md)

## Contributing

The source code for the `main` branch of this repository is on the
[src](https://github.com/fnndsc/python-chrisapp-template/tree/src)
branch, which has an additional file
[`.github/workflows/src.yml`](https://github.com/FNNDSC/python-chrisapp-template/blob/src/.github/workflows/src.yml)
When tests pass, changes are automatically merged into `main`.
Developers should commit to or make pull requests targeting `src`.
Do not push directly to `main`.

This is a workaround in order to do automatic testing of this template
without including the `.github/workflows/src.yml` file in the template itself.
