Coding style

We chose to abide by the following coding style rules.

  1. Names representing classes must be in camel case: MyClass
  2. Variable and method names must be in lower case, using underscores to separate words: my_variable, my_method()
  3. Names of protected and private members must start with an underscore: _my_private_member, _my_private_method()
  4. File names must be in lower case, using underscores to separate words. A file which contains a class MyClass should be named my_class.hpp
  5. File structure mirrors namespace structure. For instance gen::MyClass is in the file gen/my_class.hpp
  6. Named constants (including enumeration values) must be placed in the cst namespace within the current namespace
namespace cst {
  static constexpr int a_number = 3529;
}
  1. Getters should have the name of the attribute: this->_objs should be accessed using this->objs()
  2. Setters should start with "set_" followed by the name of the attribute: set_objs(const std::vector& ov)
  3. The public section should be the first section of a class
  4. Type names defined using typedefs/aliases should end with "_t": iterator_t

Code formatting

We also follow the coding style rules enforced by clang-format and a custom configuration. See the format_code repository and software to follow this standard.
