How to contribute

Thank you for showing interest in contributing to the plutopy package! Below you will find some guidelines that will get you contributing to this repository in no time!

Getting Started

  • Make sure you have a GitHub account
  • Make sure you have Git installed
  • Make sure you have Anaconda installed
  • Fork the repository on GitHub
  • Clone the repository locally

Set up a local plutopy environment

Building the Anaconda Environment

Enter the cloned plutopy directory from the shell. Run the following command to build the required Anaconda environment.

conda env create -f environment.yml

Once the dependencies have been installed, you can activate the environment with activate plutopy-env on Windows, or source activate plutopy-env on mac / Linux. For more on Anaconda environments, see the documentation here.

Installing plutopy locally

Make sure you are in the root plutopy directory and that the plutopy-env is activated. Run the following command to install a local version of plutopy (include the .):

pip install -e .

This will allow you to import plutopy as long as the plutopy-env is activated.

Keeping your fork up to date

As the main plutopy repository cjtu/plutopy is updated, your fork <your_user>/plutopy will get out of sync. This could lead to merge conflicts when you try to open a pull request on GitHub. To update your fork of plutopy, you will need to add the main plutopy repository to an upstream branch. This only needs to be done once.

cd /your/path/to/plutopy
git remote add upstream git://github.com/cjtu/plutopy.git

Now, whenever you suspect there are changes to the main plutopy repository, you can run:

git fetch upstream

If changes were downloaded, you need to merge those changes into the branch you are working on. To merge, first switch to the branch you are working on, then merge in the changes from upstream/master. If you are working on branch master:

git checkout master # Switch to the branch you want to merge the changes into
git merge upstream/master # Merges changes from the master branch of upstream

In most cases this will be a fast-forward merge and you will be good to go. In some cases you will have a merge conflict, meaning the same line(s) in the same file(s) were altered. This is a quick guide on what to do when git fails during a merge. There are many of these online guides and even tools available to visualize merge conflicts. It basically amounts to manually editing the conflicted file(s) and committing the "fixed" file(s).

Finally your local plutopy fork is up to date, but this does not change your GitHub version of the fork. To have the updated local version reflected on GitHub, you need to push your updated fork to GitHub.

git push

For more info on these steps or if you're having trouble, see the following configuring a remote for a fork, syncing a fork, and resolving a merge conflict.
