Code style

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!)

Licensing

Engine and Lua code is GPL 3. Assets (include Lua-based data files like ship defs) are CC-BY-SA 3

Include these two lines at the top of each file (suitably commented):

Tabs & spacing

• Hard tabs, 4-space aligned.
• Inner spaces after tabs to align arguments on multiple lines, etc

Constants

• Prefer static const over #define wherever possible

Name style

• Classes: FooBar
• Methods: FooBar
• Class members: m_fooBar
• Static members: s_fooBar
• Constants: FOO_BAR

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
