Code Contribution Best Practices#
This guide is to inform new contributors about the best practices followed by moja global. Before making any contribution please go through these guidelines to ensure your contribution can be merged with minimal changes.
Make sure your commit is passing all the tests. If your commit is failing tests then please try to fix the same commit instead of making a new commit by using
Every commit should be directed to solve a single problem instead of trying to solve multiple issues at once. This encourages simplicity and also makes it easier for the reviewers to review.
If the code introduced in the commit decreases the coverage/requires tests, don’t forget to add them too.
Although it’s encouraged to make commits following these guidelines but
in case you missed, you can always fix your history using
git rebase -i.
Commit Message Guidelines#
Keep the commit message short but concise explaining your changes and the problem you are trying to solve.
Try to write the commit messages in an imperative tone for example:- ‘Fix’, ‘Update’, ‘Add’ instead of ‘Fixed’, ‘Updated’, ‘Added’.
Reference the issue solved in the commit message, for example:-
Fixes #8293: Add login api unit tests. This will automatically close the issue referenced when your pull request gets merged.
Developer Certificate of Origin#
moja global follows Developer Certificate of Origin(DCO) as a method to certify that the contribution you have submitted was created in whole or in part by you and you have the right to submit it under the open source license to moja global.
To apply this, please sign off all your commit messages with a line like this:
Signed-off-by: Random J Developer <email@example.com>
Alternatively, you may also add the
--signoff flag to the
git commit command that will automatically add this line to your
Code Style & Conventions#
This section will focus on the style guidelines and conventions used by moja global across its repositories.
Depending on the language of the repository you are working on, we have an array of tools and checks to ensure that the Code Style is not violated to promote further maintainability of code.
We encourage you to add the mentioned tools as plugins in your editor.
moja global follows the C++ style guide developed by Google for their open-source projects. The google style guide is aimed at enable coders to utilise the power of C++ while at the same time managing the potential complexity that can arise when coding in C++.
The style guide can be found at: https://google.github.io/styleguide/cppguide.html
It is possible that exceptions to the google style guide may be specified, in which case they will be listed here. Currently there are no exceptions.
Coding enforcement: We know that the style guides are long and detailed and not always easy to adhere to. As such, the intention is to use Clang-Tidy as a tool to check and correct code formatting as determined by the Google C++ style guide. This will be implemented as an automated check through the Continuous Integration system.
moja global follows the Python Style guide PEP8 that provides coding conventions for Python code. It is fairly common for Python code to follow this style guide. It’s a great place to start since it’s already well-defined.
This guide can be found at : https://www.python.org/dev/peps/pep-0008/
Coding enforcement: In order to enforce the PEP8 conventions along with error detection, Pylint as a tool can be used and can be integrated with your editor as well. This will be implemented as an automated check through the Continuous Integration system.
Whenever making a contribution, please add relevant documentation to support your contribution. You may also refer to this section for a guide on how to improve/add documentation for moja global. There are five levels of documentation under moja global. Depending on your contribution, you may choose to change docs in one or more of these levels:
Documentation in the codebase#
Whenever making a significant code change like adding a new function, it is recommended to add documentation for the same in the codebase itself in form of comments.
Before commenting in the code try to clarify the code with better naming and structuring.
Use comments mainly to provide context to the reader of the code
Ensure comments are easy to maintain
Documentation in Markdown files#
Whenever adding a contribution that requires future contributors to
refer that for installation and proper development of the repository, it
is recommended to include the contribution supporting docs in the
You may choose to include it in the
README.md file if the change
requires immediate attention or you may make separate
.md files as
per the guidelines below.
README.mdfile for documentation that changes the quick installation process, usage or description of the project.
Use separate md-files for documentation that needs change in any of the following :
Submit changes using a pull-request that will be reviewed by maintainers.
If the proposed contribution requires a change in the documentation that you are currently reading on readthedocs, then follow these steps to make the changes.
Fork and clone this docs repository from here.
Since readthedocs follows
.rstfile structure, please make sure the format of your documentation is right.
Submit a pull request under the above mentioned repository for the same. You may also check how the documentation build looks under the Pull requests checks tab.
Documentation in the repository wiki#
Use the repository wiki for information that can be changed by all collaborators without review, including
Make changes and commit directly to the wiki
Since this mode of adding documentation does not require any review, we urge you to proof-read and make sure the documentation added is accurate and simple enough to understand.
Documentation in Google Docs-files#
If your contribution involves changes in the following, you may change the Google Docs for the collaborative development of documents (text equivalent of features branches), including
You may make changes/suggestions in line with the guidelines provided in this template document. The maintainer then may decide to accept/reject the suggestions offered.
Documentation in PDF-files#
If your contribution involves changes in the following, you may change the PDF-files for documentation (text equivalent of a release), including
You may suggest changes to the document maintainer. Since these PDF files are released on a version basis from the Google Doc equivalent files, if there are any errors in the current PDF the changes pointed out by you will only be released in the next version.
