Coding style guidelines
=======================
You should set tabs to display as eight spaces, not four. However,
_indentation_ should be four spaces. If possible, do not use tab
characters at all. There is a utility called "expand" which will
remove tab characters.
Please write code to an 80 column limit so that it fits within a
standard 80 column terminal.
Functions should be named like this: 'AB_FunctionName'. The 'AB' prefix
denotes the subsystem (AM_ for automap, G_ for game, etc). If a
function is static, you can omit the prefix and just name it like
'FunctionName'. Functions and global variables should always be
made static if possible.
Put '_t' on the end of types created with typedef. Type names like this
should be all lowercase and have the subsystem name at the start. An
example of this is 'txt_window_t'. When creating structures, always
typedef them.
Do not use the goto statement.
Use C++-style comments, ie. '//' comments, not '/* ... */' comments.
I don't care that this isn't standard C.
Variables should be named like this: 'my_variable_name', not like
this: 'MyVariableName'. In pointer variable declarations, place
the '*' next to the variable name, not the type.
When using an if, do, while, or for statement, always use the { }
braces even when they are not necessary. For example, do this:
if (condition)
{
body;
}
Not this:
if (condition) // NO
body;
Write code like this:
typedef struct
{
int member1;
char *member2;
} my_structure_t;
void FunctionName(int argument, int arg2, int arg3, int arg4, int arg5,
int arg6, int arg7)
{
if (condition)
{
body;
}
else if (condition)
{
body;
}
else
{
body;
}
if (very_long_condition_like_this_one_that_forces_a_line_break
&& other_condition)
{
body;
}
switch (argument)
{
case FIRST:
code;
break;
case SECOND:
code;
break;
default:
break;
}
for (a=0; a<10; ++a)
{
loop_body;
}
while (a < 10)
{
loop_body;
}
do
{
} while (condition);
}
