# Contributing to iTop
You want to contribute to iTop? Many thanks to you! 🎉 👍
Here are some guidelines that will help us integrate your work!
## Contributions
### Subjects
You are welcome to create pull requests on any of those subjects:
* 🐛 bug fix
* 🌐 translation / i18n / l10n
If you want to implement a **new feature**, please [create a corresponding ticket](https://sourceforge.net/p/itop/tickets/new/) for review.
If you ever want to begin implementation, do so in a fork, and add a link to the corresponding commits in the ticket.
For all **security related subjects**, please see our [security policy](SECURITY.md).
All **datamodel modification** should be done in an extension. Beware that such change would
impact all existing customers, and could prevent them from
upgrading!
Combodo has a long experience of datamodel changes: they are very disruptive!
This is why we avoid them in iTop core, especially the changes on existing objects/fields.
If you have an idea you're sure would benefit to all of iTop users, you may
[create a corresponding ticket](https://sourceforge.net/p/itop/tickets/new/) to submit it, but be warned that there are lots of good
reasons to refuse such changes.
### 📄 License
iTop is distributed under the AGPL-3.0 license (see the [license.txt] file),
your code must comply with this license.
If you want to use another license, you may [create an extension][wiki new ext].

## 🔀 Branch model
TL;DR:
> **create a fork from iTop main repository,
> create a branch based on the develop branch**
We are using the [GitFlow](https://nvie.com/posts/a-successful-git-branching-model/) branch model. That means we have in our repo those
main branches:
- develop: ongoing development version
- release/\*: if present, that means we are working on a beta version
- master: previous stable version
- support/\*: maintenance branches for older versions
For example, if no beta version is currently ongoing we could have:
- develop containing future 2.8.0 version
- master containing 2.7.x maintenance version
- support/2.6 containing 2.6.x maintenance version
- support/2.5 containing 2.5.x maintenance version
In this example, when 2.8.0-beta is shipped that will become:
- develop: future 2.9.0 version
- release/2.8: 2.8.0-beta
- master: 2.7.x maintenance version
- support/2.6 containing 2.6.x maintenance version
- support/2.5 containing 2.5.x maintenance version
And when 2.8.0 final will be out:
- develop: future 2.9.0 version
- master: 2.8.x maintenance version
- support/2.7 : 2.7.x maintenance version
- support/2.6 containing 2.6.x maintenance version
- support/2.5 containing 2.5.x maintenance version
Most of the time you should based your developments on the develop branch.
That may be different if you want to fix a bug, please use develop anyway and ask in your PR if rebase is possible.
## Coding
### 🎨 PHP styleguide
Please follow [our guidelines](https://www.itophub.io/wiki/page?id=latest%3Acustomization%3Acoding_standards).
### 🌐 Translations
A [dedicated page](https://www.itophub.io/wiki/page?id=latest%3Acustomization%3Atranslation) is available in the official wiki.
### ✅ Tests
Please create tests that covers as much as possible the code you're submitting.
Our tests are located in the `test/` directory, containing a PHPUnit config file : `phpunit.xml.dist`.
### Git Commit Messages
* Describe the functional change instead of the technical modifications
* Use the present tense ("Add feature" not "Added feature")
* Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
* Limit the first line to 72 characters or less
* Please start the commit message with an applicable emoji code (following the [Gitmoji guide](https://gitmoji.carloscuesta.me/)).
Beware to use the code (for example `:bug:`) and not the character (🐛) as Unicode support in git clients is very poor for now...
Emoji examples :
* 🌐 `:globe_with_meridians:` for translations
* 🎨 `:art:` when improving the format/structure of the code
* ⚡️ `:zap:` when improving performance
* 🐛 `:bug:` when fixing a bug
* 🔥 `:fire:` when removing code or files
* 💚 `:green_heart:` when fixing the CI build
*`:white_check_mark:` when adding tests
* 🔒 `:lock:` when dealing with security
* ⬆️ `:arrow_up:` when upgrading dependencies
* ⬇️ `:arrow_down:` when downgrading dependencies
* ♻️ `:recycle:` code refactoring
* 💄 `:lipstick:` Updating the UI and style files.
## 👥 Pull request
When your code is working, please:
