C++ Coding Style
================

Kakoune is written in C++11, here are the main coding style points:

 * Avoid external dependencies besides posix/stdc++/ncurses

 * 4 spaces for indentation, no tabs

 * public interface before private methods/data when defining a class

 * use +override+ keyword for overridden virtual methods

 * opening brackets on their own lines by default, except when declaring
   an object where the opening bracket follows the equal sign.

-----
int func()
{
    if (condition)
    {
        ...
    }
    else
        statement;
}

int array[] = {
...
};
-----

 * End lines with an operator when continuing on the next line

----
if (condition1 ||
    condition2)
----

 * Try to keep under 80 columns, even though this is not a strict limit.

 * CamelCase for types, snake_case for variables/function names

 * prefix fields with m_, static ones with ms_ except for dumb structs
   (struct with every field public) where these prefixes can be dropped.

 * use const and constexpr liberally
