source: pacpusframework/trunk/CODING_STYLE.txt@ 55

For the aspects not explained in this document, follow the coding style described in:
    http://llvm.org/docs/CodingStandards.html

== #include Style ==
* Avoid #includes in the header files. Use forward declarations if possible.
* Immediately after the header file comment (and include guards if working on a header file), the minimal list of #includes required by the file should be listed. We prefer these #includes to be listed in this order:
    1) Main Module Header
    2) Local/Private Headers
    3) <Pacpus/...>
    4) System #includes
* do not use 'using ...;' in header files

== Mechanical Source Issues ==
* use standard header-guard:
    #ifndef PACPUS_EXAMPLE_H
    #define PACPUS_EXAMPLE_H
    ...
    #endif // PACPUS_EXAMPLE_H
* use C++-style comments (//)
* ALWAYS use curly brackets with statements if, for, etc.
* use curly brackets {} as follows:
    * on the same line with:
        - namespace {
        - statements if, for, etc.
            if (cond) {
            } else if (cond2) {
            } else {
            }
    * on the next line with:
        - classes
        - function and method definitions
        - local scope blocks
            class A
            {
                void fun A;
                
                struct AB
                {
                };
                
                void fun A
                {
                }
            };
* write Doxygen-style comments as much as possible, put it in the header file if possible, add developer-only comments in source file
* use Java-style Doxygen comments, i.e. @returns over \returns
* use preprocessor directives for long-range comments (#if 0 .... #endif)
* indent with 4 spaces, do not use tabs
* do not indent namespaces
* use camelCaseNotation / CamelCaseNotation
* end namespace with its name in a comment 
* start with a lowercase letter for local variables, namespaces, function names, method names, ...
* start with an Uppercase for classes, structs, ...
* prefix member variables with 'm'
* prefix (static) const variables with 'k'
* prefix static (non-const) variables with 's'
* separate member methods from member variables with a repetion of 'protected:' / 'private:'
