C++ Coding Style
|
|
================
|
|
|
|
Kakoune is written in C++11, here are the main coding style points:
|
|
|
|
* Avoid external dependencies besides posix/stdc++/ncurses
|
|
|
|
- That means avoid depending on boost, it is only allowed for the regex
|
|
implementation. The reference for the current regex support is available under
|
|
http://www.boost.org/doc/libs/release/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html[Perl Regular Expression Syntax].
|
|
|
|
* 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
|
|
|
|
Kakrc coding style
|
|
==================
|
|
|
|
* kak scripts can depend on tools that can be reasonable expected for
|
|
their use context:
|
|
|
|
- mime.kak which handles file type detection uses the +file+ command
|
|
which is deemed ubiquitous enough.
|
|
|
|
- clang.kak provides c++ completion using clang,
|
|
|
|
* It is better to keep kak scripts POSIX. Consider %sh{...} blocks
|
|
as executed by a POSIX shell. Avoid non posix extensions to common
|
|
tools.
|
|
|
|
* Avoid too much complexity/logic in kak scripts. They are not meant
|
|
to implement generic tools, only to transform a general tool output
|
|
to Kakoune commands.
|
|
|
|
- Write generic, editor independent tools as a separate project,
|
|
Add kakoune support as a kak script.
