| − | This page describes some of the code style used in Pioneer. Its probably incomplete, but it should be correct. If you see something in the code that doesn't match what's described here, this guide takes precedence (and please submit a patch to fix it!)

| − | == Tabs & spacing ==
| |
| − | | |
| − | * Hard tabs, 4-space aligned.
| |
| − | * Inner spaces after tabs to align arguments on multiple lines, etc
| |
| − | | |
| − | == Constants ==
| |
| − | | |
| − | * Prefer <tt>static const</tt> over <tt>#define</tt> wherever possible

| − | == Name style ==
| |
| − | | |
| − | * Classes: FooBar
| |
| − | * Methods: FooBar
| |
| − | * Class members: m_fooBar
| |
| − | * Static members: s_fooBar
| |
| − | * Constants (defines and <tt>static const</tt>): FOO_BAR

| − | Names should generally be chosen for what the thing represents. It shouldn't have type or qualifier information embedded in the name (the so-called [http://en.wikipedia.org/wiki/Hungarian_notation Systems Hungarian] notation). Just name it so its crystal clear what it is.
| |
| − | | |
| − | (Exception: member variables have a <tt>m_</tt> or <tt>s_</tt> to disambiguate them from local names and to match C++ conventions).
| |
| − | | |
| − | There's also a few abbreviated names that are commonly used throughout the codebase, eg <tt>Renderer *r</tt>, <tt>lua_State *l</tt>, etc. Try to prefer them where appropriate.

| − | | |
| − | == Include guards ==
| |
| − | | |
| − | Header include guards should be named for the filename of the header, capitalised, with slashes converted to underscores:
| |
| − | | |
| − | * Ship.h
| |
| − | #ifndef SHIP_H
| |
| − | | |
| − | * WorldView.h
| |
| − | #ifndef WORLDVIEW_H
| |
| − | | |
| − | * graphics/Renderer.h
| |
| − | #ifndef GRAPHICS_RENDERER_H
| |
| − | | |
| − | == Enum types ==
| |
| − | | |
| − | Enums are effectively global constants, so should be in full caps. They're prefixed with the name of the enum.
| |
| − | | |
| − | Avoid assigning explicit integer values. Also avoid values that aren't actually valid for whatever the enum is (though *_MAX to mark the last valid value is usually acceptable). If these don't work, chances are what you're trying to do would be better served by multiple enums or even a whole class.

| − | THING_BAZ,
