# Contributing to this project

Please take a moment to review this document in order to make the contribution
process easy and effective for everyone involved.

Following these guidelines helps to communicate that you respect the time of
the developers managing and developing this open source project. In return,
they should reciprocate that respect in addressing your issue or assessing
patches and features.


## Using the issue tracker

The issue tracker is the preferred channel for [bug reports](#bugs),
[features requests](#features) and [submitting pull
requests](#pull-requests), but please respect the following restrictions:

* Please **do not** use the issue tracker for personal support requests (use
  [Stack Overflow](http://stackoverflow.com)).

* Please **do not** derail or troll issues. Keep the discussion on topic and
  respect the opinions of others.

## Bug reports

A bug is a _demonstrable problem_ that is caused by the code in the repository.
Good bug reports are extremely helpful - thank you!

Guidelines for bug reports:

1. **Use the GitHub issue search** &mdash; check if the issue has already been
   reported.

2. **Check if the issue has been fixed** &mdash; try to reproduce it using the
   latest `master` or development branch in the repository.

3. **Isolate the problem** &mdash; ideally create a [reduced test
   case](http://css-tricks.com/6263-reduced-test-cases/) and a live example (you can use something like [jsfiddle](http://jsfiddle.net/) or [jsbin](http://jsbin.com/)) .

A good bug report shouldn't leave others needing to chase you up for more
information. Please try to be as detailed as possible in your report. What is
your environment? What steps will reproduce the issue? What browser(s) and OS
experience the problem? What would you expect to be the outcome? All these
details will help people to fix any potential bugs.

Example:

> Short and descriptive example bug report title
>
> A summary of the issue and the browser/OS environment in which it occurs. If
> suitable, include the steps required to reproduce the bug.
>
> 1. This is the first step
> 2. This is the second step
> 3. Further steps, etc.
>
> `<url>` - a link to the reduced test case
>
> Any other information you want to share that is relevant to the issue being
> reported. This might include the lines of code that you have identified as
> causing the bug, and potential solutions (and your opinions on their
> merits).

## Feature requests

Feature requests are welcome. But take a moment to find out whether your idea
fits with the scope and aims of the project. It's up to *you* to make a strong
case to convince the project's developers of the merits of this feature. Please
provide as much detail and context as possible.

**Please, use the GitHub issue search** to check if the feature has already been requested.


<a name="pull-requests"></a>
## Pull requests

Good pull requests - patches, improvements, new features - are a fantastic
help. They should remain focused in scope and avoid containing unrelated
commits.

**Please ask first** before embarking on any significant pull request (e.g.
implementing features, refactoring code, porting to a different language),
otherwise you risk spending a lot of time working on something that the
project's developers might not want to merge into the project.

Code must follow, mostly, these [coding conventions](http://javascript.crockford.com/code.html) .

Adhering to the following this process is the best way to get your work
included in the project:

1. [Fork](http://help.github.com/fork-a-repo/) the project, clone your fork,
   and configure the remotes:

   ```bash
   # Clone your fork of the repo into the current directory
   git clone https://github.com/<your-username>/gridster.js
   # Navigate to the newly cloned directory
   cd gridster.js
   # Assign the original repo to a remote called "upstream"
   git remote add upstream https://github.com/ducksboard/gridster.js
   ```

2. If you cloned a while ago, get the latest changes from upstream:

   ```bash
   git checkout master
   git pull upstream master
   ```

3. Create a new topic branch (off the main project development branch) to
   contain your feature, change, or fix:

   ```bash
   git checkout -b <topic-branch-name>
   ```

4. Commit your changes in logical chunks. Please adhere to these [git commit
   message guidelines](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y)
   or your code is unlikely be merged into the main project. Use Git's
   [interactive rebase](https://help.github.com/articles/interactive-rebase)
   feature to tidy up your commits before making them public.

5. Merge or rebase the upstream development branch into your topic branch:

   ```bash
   git pull --rebase upstream master
   ```

6. Push your topic branch up to your fork:

   ```bash
   git push origin <topic-branch-name>
   ```

7. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/)
    with a clear title and description.

**IMPORTANT**: By submitting a patch, you agree to allow the project owner to
license your work under the same license as that used by the project.


#commit Message Guidelines
We use [automatic changelog creation](https://github.com/ajoslin/conventional-changelog), so it best if your commit messages follow the following conventions:

### Commit Message Format
Each commit message consists of a **header**, a **body** and a **footer**.  The header has a special
format that includes a **type**, a **scope** and a **subject**:

```
<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
```

Any line of the commit message cannot be longer 100 characters! This allows the message to be easier
to read on github as well as in various git tools.

### Type
Must be one of the following:

* **feat**: A new feature
* **fix**: A bug fix
* **docs**: Documentation only changes
* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing
  semi-colons, etc)
* **refactor**: A code change that neither fixes a bug or adds a feature
* **perf**: A code change that improves performance
* **test**: Adding missing tests
* **chore**: Changes to the build process or auxiliary tools and libraries such as documentation
  generation

### Scope
The scope could be anything specifying place of the commit change. For example `$location`,
`$browser`, `$compile`, `$rootScope`, `ngHref`, `ngClick`, `ngView`, etc...

### Subject
The subject contains succinct description of the change:

* use the imperative, present tense: "change" not "changed" nor "changes"
* don't capitalize first letter
* no dot (.) at the end

### Body
Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes"
The body should include the motivation for the change and contrast this with previous behavior.

### Footer
The footer should contain any information about **Breaking Changes** and is also the place to
reference GitHub issues that this commit **Closes**.

**Breaking Changes** are detected as such if the Body contains a line starting with
`BREAKING CHANGES:` The rest of the commit message is then used for this.
