# Coding style
|
||||
|
||||
I started writing in [Plan 9 style](http://man.cat-v.org/plan_9/6/style),
|
||||
but realize that this is not the most popular style, so I'm willing to compromise.
|
||||
Try not to deviate too much so the code will look similar across the whole project.
|
||||
|
||||
To give examples, these two styles (or anything in between) are fine:
|
||||
|
||||
```
|
||||
type
|
||||
functionname(args)
|
||||
{
|
||||
if(a == b){
|
||||
s1;
|
||||
s2;
|
||||
}else{
|
||||
s3;
|
||||
s4;
|
||||
}
|
||||
if(x != y)
|
||||
s5;
|
||||
}
|
||||
|
||||
type functionname(args)
|
||||
{
|
||||
if (a == b) {
|
||||
s1;
|
||||
s2;
|
||||
} else {
|
||||
s3;
|
||||
s4;
|
||||
}
|
||||
if (x != y)
|
||||
s5;
|
||||
}
|
||||
```
|
||||
|
||||
This one (or anything more extreme) is heavily discouraged:
|
||||
|
||||
```
|
||||
type functionname ( args )
|
||||
{
|
||||
if ( a == b )
|
||||
{
|
||||
s1;
|
||||
s2;
|
||||
}
|
||||
else
|
||||
{
|
||||
s3;
|
||||
s4;
|
||||
}
|
||||
if ( x != y )
|
||||
{
|
||||
s5;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
i.e.
|
||||
|
||||
* Put the brace on the same line as control statements
|
||||
|
||||
* Put the brace on the next line after function definitions and structs/classes
|
||||
|
||||
* Put an `else` on the same line with the braces
|
||||
|
||||
* Don't put braces around single statements
|
||||
|
||||
* Put the function return type on a separate line
|
||||
|
||||
* Indent with TABS
|
||||
|
||||
As for the less cosmetic choices, here are some guidelines how the code should look:
|
||||
|
||||
* Don't use magic numbers where the original source code would have had an enum or similar.
|
||||
Even if you don't know the exact meaning it's better to call something `FOOBAR_TYPE_4` than just `4`,
|
||||
since `4` will be used in other places and you can't easily see where else the enum value is used.
|
||||
|
||||
* Don't just copy paste code from IDA, make it look nice
|
||||
|
||||
* Use the right types. In particular:
|
||||
|
||||
* don't use types like `__int16`, we have `int16` for that
|
||||
|
||||
* don't use `unsigned`, we have typedefs for that
|
||||
|
||||
* don't use `char` for anything but actual characters, use `int8`, `uint8` or `bool`
|
||||
|
||||
* don't even think about using win32 types (`BYTE`, `WORD`, &c.) unless you're writing win32 specific code
|
||||
|
||||
* declare pointers like `int *ptr;`, not `int* ptr;`
|
||||
|
||||
* As for variable names, the original gta source code was not written in a uniform style,
|
||||
but here are some observations:
|
||||
|
||||
* many variables employ a form of hungarian notation, i.e.:
|
||||
|
||||
* `m_` may be used for class member variables (mostly those that are considered private)
|
||||
|
||||
* `ms_` for (mostly private) static members
|
||||
|
||||
* `f` is a float, `i` or `n` is an integer, `b` is a boolean, `a` is an array
|
||||
|
||||
* do *not* use `dw` for `DWORD` or so, we're not programming win32
|
||||
|
||||
* Generally, try to make the code look as if R* could have written it

- Clone the repo.

- Run `git submodule init` and `git submodule update`.
