Welcome to the page of our Coding Style Guidelines!

Our Coding Style Guidelines are oriented to the Guidelines of Google and Gnu GCC. If you are unsure how to code and your problem is not explicitly mentioned in this guide, please have a look at

https://gcc.gnu.org/codingconventions.html

or

https://google.github.io/styleguide/cppguide.html

Thank you!

PS: We know, that in the existing code, a lot of files are not following our guidelines. Please feel free to correct this and of course, don't follow the bad examples!

Documentation

For Documentation Style Guide please look up our Documentation Style Guidelines!

Thank you!

Braces

Please open your curly braces in the same line as the name of the function like

if (hours < 24 && minutes < 60 && seconds < 60) {
    return true;
} 
else {
    return false;
}

Header Files

In general, every .cc file should have an associated .hh file (not a .h file, this has historical reasons and should stay constant). There are some common exceptions, such as unit tests and small .cc files containing just a main() function. Correct use of header files can make a huge difference to the readability, size, and performance of your code.

Variable Definitions

Variables should be defined at the top of the functions or methods, not at the first use. This is just about the readability. Please don't define variables in between!

Tab Width

Please use four spaces for a tab. Please don't use normal tabs! Most editors are able to do this for you. Gedit does this by default.
