###Coding standards
For the sake of consistency between contribution and general code readability, Friendica follows the widespread [PSR-2 coding standards](http://www.php-fig.org/psr/psr-2/) to the exception of a few rules.
Here's a few primers if you are new to Friendica or to the PSR-2 coding standards:
* Indentation is tabs, period (not PSR-2).
* By default, strings are enclosed in single quotes, but feel free to use double quotes if it makes more sense (SQL queries, adding tabs and line feeds).
* Operators are wrapped by spaces, e.g. `$var === true`, `$var = 1 + 2` and `'string' . $concat . 'enation'`
* Braces are mandatory in conditions
* No closing PHP tag
* No trailing spaces
Don't worry, you don't have to know by heart the PSR-2 coding standards to start contributing to Friendica.
There are a few tools you can use to check or fix your files before you commit.
####Check with [PHP Code Sniffer](https://github.com/squizlabs/PHP_CodeSniffer)
This tool checks your files against a variety of coding standards, including PSR-2, and ouputs a report of all the standard violations.
You can simply install it through PEAR: `pear install PHP_CodeSniffer`
Once it is installed and available in your PATH, here's the command to run before committing your work:
$> phpcs --standard=PSR2 <file or directory>
The output is a list of all the coding standards violations that you should fix before committing your work.
Additionally, `phpcs` integrates with a few IDEs (Eclipse, Netbeans, PHPStorm...) so that you don't have to fiddle with the command line.
####Fix with PHP Code Beautifier and Fixer (phpbcf) included in PHP Code Sniffer
If you're getting a massive list of standards violations when running `phpcs`, it can be annoying to fix all the violations by hand.
Thankfully, PHP Code Sniffer is shipped with an automatic code fixer that can take care of the tedious task for you.
Here's the command to automatically fix the files you created/modified:
$> phpcbf --standard=PSR2 <file or directory>
If the command-line tools `diff` and `patch` are unavailabe for you, `phpcbf` can use slightly slower PHP equivalents by using the `--no-patch` argument.
###Code documentation
If you are interested in having the documentation of the Friendica code outside of the code files, you can use [Doxygen](http://doxygen.org) to generate it.
The configuration file for Doxygen is located in the ```util``` directory of the project sources.

Run
$> doxygen util/Doxyfile
