For Developers

To run this project locally, you will need to install the prerequisites and follow the installation section.

Prerequisites

This Project depends on the poetry.

1. Install poetry, via homebrew or pipx:

   brew install poetry

   or

   pipx install poetry

2. Don't forget to use the python environment you set before and, if using VScode, apply it there.

3. It's optional, but we strongly recommend commitizen, which follows Conventional Commits

Installation

1. Clone the repo

   git clone https://github.com/pontikos-lab/process-dcm
   cd process-dcm

Bumping Version

We use commitizen. The instructions below are only for exceptional cases.

1. Using poetry-bumpversion. Bump the version number by running poetry version [part] [--dry-run] where [part] is major, minor, or patch, depending on which part of the version number you want to bump.

   Use --dry-run option to check it in advance.

2. Push the tagged commit created above and the tag itself, i.e.:

   ver_tag=$(poetry version | cut -d ' ' -f2)
   git tag -a v"$ver_tag" -m "Tagged version $ver_tag"
   git push
   git push --tags
