Hello everyone, we agreed some time ago, that we would use PSR-2 code style for xRes development. http://confluence.app.infra.gs.xtrav.de/display/Entwicklung/Codestyles PSR-2 however is a very general recommendation. Many things we do intuitively, I believe it's time to extend a little bit a list of our rules, to make them more clear. My proposal is to partially adopt Symfony Framework Coding Stadard, since it shares a lot of rules with what we already do. https://symfony.com/doc/3.3/contributing/code/standards.html Specifically: - Follow the standards defined in the PSR-0, PSR-1, PSR-2 and PSR-4 documents. - Add a single space after each comma delimiter (E.g. func($a, $b, $c); or [$a, $b, $c]) - Add a single space around binary operators (==, &&, ...). I suggest always use spaces around concatenation as well. (E.g. $a . $b, $a == $b) - Place unary operators (!, --, ...) adjacent to the affected variable (E.g. !$a, not ! $a) - Use braces to indicate control structure body regardless of the number of statements it contains; (E.g. if ($a) { doThis(); }) - Declare class properties before methods; - Use parentheses when instantiating classes regardless of the number of arguments the constructor has; (E.g. new Obj(); not new Obj;) - Do not use spaces around [ offset accessor and before ] offset accessor. (E.g. $a[$b[1]], not $a[ $b[1] ]) - Use camelCase, not underscores, for variable, function and method names, arguments; - Prefix abstract classes with Abstract - Suffix interfaces with Interface - Suffix traits with Trait - Suffix exceptions with Exception - Use alphanumeric characters and underscores for file names (Letters and numbers, no special characters) - For type-hinting in PHPDocs and casting, use bool (instead of boolean or Boolean), int (instead of integer), float (instead of double or real); - Omit the @return tag if the method does not return anything; - The @package and @subpackage annotations are not used. These are just, what I believe we can easily agree on without much discussion. There are more rules in the Symfony document. If you feel some other should also be included - please let everyone know.
