If you want to make a change, it's a good idea to first open an issue and make sure someone from the team agrees that it’s needed.
If you've decided to work on an issue, assign yourself to the issue so others will know you're working on it.
We use GitHub Flow as our collaboration process. Follow the steps below for detailed instructions on contributing changes to CHAMPAGNE.
If you are a member of CCBR, you can clone this repository to your computer or development environment. Otherwise, you will first need to fork the repo and clone your fork. You only need to do this step once.

cd CHAMPAGNE-
Install nextflow and singularity or docker if needed (biowulf already has these available as modules).
-
Install the python dependencies with pip
pip install .If you're developing on biowulf, you can use our shared conda environment which already has these dependencies installed
. "/data/CCBR_Pipeliner/db/PipeDB/Conda/etc/profile.d/conda.sh" conda activate py311
-
Install
pre-commitif you don't already have it. Then from the repo's root directory, runpre-commit install
This will install the repo's pre-commit hooks. You'll only need to do this step the first time you clone the repo.
Create a Git branch for your pull request (PR). Give the branch a descriptive
name for the changes you will make, such as iss-10 if it is for a specific
issue.
# create a new branch and switch to it
git branch iss-10
git switch iss-10Switched to a new branch 'iss-10'
Edit the code, write and run tests, and update the documentation as needed.
Changes to the python package code will also need unit tests to demonstrate
that the changes work as intended.
We write unit tests with pytest and store them in the tests/ subdirectory.
Run the tests with python -m pytest.
If you change the workflow, please run the workflow with the test profile and make sure your new feature or bug fix works as intended.
If you have added a new feature or changed the API of an existing feature,
you will likely need to update the documentation in docs/.
If you're not sure how often you should commit or what your commits should consist of, we recommend following the "atomic commits" principle where each commit contains one new feature, fix, or task. Learn more about atomic commits here: https://www.freshconsulting.com/insights/blog/atomic-commits/
First, add the files that you changed to the staging area:
git add path/to/changed/files/Then make the commit.
Your commit message should follow the
Conventional Commits
specification.
Briefly, each commit should start with one of the approved types such as
feat, fix, docs, etc. followed by a description of the commit.
Take a look at the Conventional Commits specification
for more detailed information about how to write commit messages.
git commit -m 'feat: create function for awesome feature'pre-commit will enforce that your commit message and the code changes are styled correctly and will attempt to make corrections if needed.

In the example above, one of the hooks modified a file in the proposed commit,
so the pre-commit check failed. You can run git diff to see the changes that
pre-commit made and git status to see which files were modified. To proceed
with the commit, re-add the modified file(s) and re-run the commit command:
git add path/to/changed/files/file.txt
git commit -m 'feat: create function for awesome feature'This time, all the hooks either passed or were skipped (e.g. hooks that only run on R code will not run if no R files were committed). When the pre-commit check is successful, the usual commit success message will appear after the pre-commit messages showing that the commit was created.

We recommend pushing your commits often so they will be backed up on GitHub.
You can view the files in your branch on GitHub at
https://github.com/CCBR/CHAMPAGNE/tree/<your-branch-name>
(replace <your-branch-name> with the actual name of your branch).
Once your branch is ready, create a PR on GitHub: https://github.com/CCBR/CHAMPAGNE/pull/new/
Select the branch you just pushed:
Edit the PR title and description.
The title should briefly describe the change.
Follow the comments in the template to fill out the body of the PR, and
you can delete the comments (everything between <!-- and -->) as you go.
Be sure to fill out the checklist, checking off items as you complete them or
striking through any irrelevant items.
When you're ready, click 'Create pull request' to open it.
Optionally, you can mark the PR as a draft if you're not yet ready for it to be reviewed, then change it later when you're ready.
We will do our best to follow the tidyverse code review principles: https://code-review.tidyverse.org/. The reviewer may suggest that you make changes before accepting your PR in order to improve the code quality or style. If that's the case, continue to make changes in your branch and push them to GitHub, and they will appear in the PR.
Once the PR is approved, the maintainer will merge it and the issue(s) the PR links will close automatically. Congratulations and thank you for your contribution!
After your PR has been merged, update your local clone of the repo by switching to the main branch and pulling the latest changes:
git checkout main
git pullIt's a good idea to run git pull before creating a new branch so it will
start from the most recent commits in main.
