Cogl Coding Style
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
This document is intended to be a short description of the preferred
|
||
|
|
coding style to be used for the Cogl source code.
|
||
|
|
|
||
|
|
Coding style is a matter of consistency, readability and maintainance;
|
||
|
|
coding style is also completely arbitrary and a matter of taste. This
|
||
|
|
document will use examples at the very least to provide authoritative
|
||
|
|
and consistent answers to common questions regarding the coding style,
|
||
|
|
and will also try to identify the allowed exceptions.
|
||
|
|
|
||
|
|
The Cogl coding style is currently defined relative to the Clutter
|
||
|
|
coding style, so please first read clutter/docs/CODING_STYLE.
|
||
|
|
|
||
|
|
Differences to the Clutter coding style:
|
||
|
|
|
||
|
|
+ Headers
|
||
|
|
|
||
|
|
Cogl headers are not exempt from the 80 characters limit as they are in
|
||
|
|
Clutter. Function prototypes should not be arranged into vertical
|
||
|
|
columns but should instead follow the "+ Functions" section of the
|
||
|
|
Clutter CODING_STYLE like:
|
||
|
|
|
||
|
|
void
|
||
|
|
my_function (CoglType type,
|
||
|
|
CoglType *a_pointer,
|
||
|
|
CoglType another_type);
|
||
|
|
|
||
|
|
+ Types
|
||
|
|
|
||
|
|
Avoid the use of redundant glib typedefs and wherever possible simply
|
||
|
|
use ANSI C types.
|
||
|
|
|
||
|
|
The following types should not be used:
|
||
|
|
gint, guint, gfloat, gdouble, glong, gulong, gchar and guchar
|
||
|
|
Instead use:
|
||
|
|
int, unsigned int, float, double, long, unsigned long, char, and
|
||
|
|
guint8/unsigned char
|
||
|
|
|
||
|
|
The glib types that we continue to use for portability are gboolean,
|
||
|
|
gint{8,16,32,64}, guint{8,16,32,64} and gsize. When ever you need a
|
||
|
|
byte size type for dealing with pixel data then guint8 should be used.
|
||
|
|
|
||
|
|
The general intention is that Cogl should look palatable to the widest
|
||
|
|
range of C programmers including those outside the Gnome community so
|
||
|
|
- especially for the public API - we want to minimize the number of
|
||
|
|
foreign looking typedefs.
