QuakeForge Coding Style
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
You /WILL/ indent with hard tabs, or you will be harmed. :) You can
|
|
format for whatever tab spacing you like, but if you indent with spaces
|
|
you will be hurt and you will have deserved it. :)
|
|
|
|
For best results, and to keep other developers from saying things like
|
|
"what bastard formatted this?", you should use 4-space tabs, because
|
|
that's what id used and what most of us use. This is only a guideline,
|
|
though, not a requirement.
|
|
|
|
Each source file should have a standard comment, formatted as in the
|
|
example below.
|
|
|
|
When you create a new source file, make sure you put an RCS ID below the
|
|
opening comment. One of the things this lets us do is use the "ident"
|
|
tool (comes with RCS) to identify all of the source files compiled into
|
|
an executable. This is done by embedding [dollar sign]Id: [dollar sign]
|
|
into the file, and CVS will automagically add the version information to
|
|
the source file.
|
|
|
|
All source files MUST #include "config.h" if the symbol HAVE_CONFIG_H
|
|
is defined. Likewise, no source file may be compiled multiple times to
|
|
produce different object files -- one source, one object.
|
|
|
|
Atop each function you write, you should attach a /* */ comment heading,
|
|
containing the name and a short, DESCRIPTIVE summary of the function's
|
|
purpose. Indent both of these with one or more tabs. The function is to
|
|
immediately follow the heading, with no space between. When you move or
|
|
rename a function, or change what it does, change the heading to match.
|
|
|
|
The return type should be located on the line previous to the function's
|
|
name, and the function's name should begin with the very first character
|
|
of a line. This is to facilitate easy searches for a function using the
|
|
simple regular expression "^FuncName".
|
|
|
|
Functions that do not take a value should be explicitly declared to
|
|
accept void, not simply ().
|
|
|
|
On brace style: QuakeForge code uses "cuddled" braces, also called K&R
|
|
and the One True Brace Style (yes, it really is called that), so-called
|
|
because it is the brace style used by the creators of the C language.
|
|
|
|
Please use a prefix for new functions. The currently-defined prefixes
|
|
are described below:
|
|
|
|
Cross-target prefixes:
|
|
IN_ Input
|
|
JOY_ Joystick (called by IN_* functions)
|
|
R_ Rendering
|
|
S_ Sound
|
|
VID_ Low-level video
|
|
|
|
Target-specific prefixes:
|
|
|
|
CL_ Client
|
|
GL_ OpenGL rendering
|
|
QFGL_ OpenGL portability aids
|
|
SNDDMA_ DMA Sound (called from S_*)
|
|
SV_ Server
|
|
SW_ Software rendering
|
|
X11_ X11R6-specific window handling
|
|
|
|
An example:
|
|
|
|
/*
|
|
filename.c
