# Contributing Guidelines We love improvements to our tools! There are a few key ways you can help us improve our projects: ### Submitting Feedback, Requests, and Bugs Our process for submitting feedback, feature requests, and reporting bugs usually begins by discussion on [our chat](http://wiki.kiwix.org/wiki/Communication#Chat) and, after initial clarification, through [GitHub issues](https://help.github.com/articles/about-issues/). Each project repository generally maintains its own set of issues: https://github.com/kiwix//issues Some projects have additional templates or sets of questions for each issue, which you will be prompted to fill out when creating one. Issues that span multiple projects or are about coordinating how we work overall are in the [Overview Issue Tracker](https://github.com/kiwix/overview/issues). ### Submitting Code and Documentation Changes We still do not have [project guidelines](./guidelines/project_guidelines.md) for all of the projects hosted in our [GitHub Organization](https://github.com/kiwix), which new repositories should follow during their creation. Our process for accepting changes operates by [Pull Request (PR)](https://help.github.com/articles/about-pull-requests/) and has a few steps: 1. If you haven't submitted anything before, and you aren't (yet!) a member of our organization, **fork and clone** the repo: $ git clone git@github.com:/.git Organization members should clone the upstream repo, instead of working from a personal fork: $ git clone git@github.com:kiwix/.git 1. Create a **new branch** for the changes you want to work on. Choose a topic for your branch name that reflects the change: $ git checkout -b 1. **Create or modify the files** with your changes. If you want to show other people work that isn't ready to merge in, commit your changes then create a pull request (PR) with _WIP_ or _Work In Progress_ in the title. https://github.com/kiwix//pull/new/master 1. Once your changes are ready for final review, commit your changes then modify or **create your pull request (PR)**, assign as a reviewer or ping (using "`@`") a Lieutenant (someone able to merge in PRs) active on the project (all Lieutenants can be pinged via `@kiwix/lieutenants`) 1. Allow others sufficient **time for review and comments** before merging. We make use of GitHub's review feature to comment in-line on PRs when possible. There may be some fixes or adjustments you'll have to make based on feedback. 1. Once you have integrated comments, or waited for feedback, a Lieutenant should merge your changes in! ### Branching Our branching strategy is based on [this article](https://nvie.com/posts/a-successful-git-branching-model/) which we suggest you read. + **master** a history of releases, once merged to from develop and tagged we create a release on the play store & GitHub releases. + **develop** the actively worked on next release of the app, what we branch off of while working on new features and what we merge into upon feature completion + **feature/** or feature/\/ any branch under this directory is an actively developed feature, feature branches culminate in a PR, are merged and deleted. Typically a feature branch is off of develop and into develop but in rare scenarios if there is an issue in production a branch may be made off master to fix this issue, this type of feature branch must be merged to develop and master before being deleted. Branch names should be in the format **#\-kebab-case-title** All branches should have distinct history and should be visually easy to follow, for this reason only perform merge commits when merging code either by PR or when synchronising. If you wish to rebase you should be following the [Golden Rule](https://www.atlassian.com/git/tutorials/merging-vs-rebasing#the-golden-rule-of-rebasing) and ahere to the advice in the heading [Aside: Rebase as cleanup is awesome in the coding lifecycle](https://www.atlassian.com/git/articles/git-team-workflows-merge-or-rebase). ### Building The default build is `debug`, with this variant you can use a debugger while developing. To install the application click the `run` button in Android Studio with the `app` configuration selected while you have a device connected. All other build types but `release` can be ignored, the `release` build is what gets uploaded to the Google Play store and can be built locally with the dummy credentials/keystore provided. By default we fetch kiwix-lib, the key component for interacting with ZIM files from maven, but if you wish to use your own locally compiled version for testing purposes, then you can create the directory `app/libs` and place your .aar file inside it to have it used instead. ### Testing Unit tests are located in `app/src/test` and to run them locally you can use the gradle command: $ gradlew testKiwixDebugUnitTest or the abbreviated: $ gradlew tKDUT Automated tests that require a connected device (UI related tests) are located in `app/src/androidTest` & `app/src/androidTestKiwix`, to run them locally you can use the gradle command: $ gradlew connectedKiwixDebugAndroidTest or the abbreviated: $ gradlew cKDAT All local test results can be seen under `app/build/reports/` ### Code coverage To generate coverage reports for your unit tests run: $ gradlew jacocoTestKiwixDebugUnitTest To generate coverage reports for your automated tests run: $ gradlew createKiwixDebugCoverageReport Code coverage results can be seen under `app/build/reports/` ### Continous Integration All PRs will have all these tests run and a combined coverage report will be attached, if coverage is to go down the PR will be marked failed. On Travis CI the automated tests are run on an emulator. To learn more about the commands run on the CI please refer to [.travis.yml](https://github.com/kiwix/kiwix-android/blob/master/.travis.yml) _These guidelines are based on [Tools for Government Data Archiving](https://github.com/edgi-govdata-archiving/overview/blob/master/CONTRIBUTING.md)'s._
