# Contributing to Graphene
If you found a bug (which I'm sure there will be plenty), or if you want
to add your own pet feature, then follow these steps:
1. Fork the [ebassi/graphene](https://github.com/ebassi/graphene) repo
2. Fix bugs or add new features and push them to your clone
3. Open [a new issue](https://github.com/ebassi/graphene/issues/new)
4. Open [a pull request](https://github.com/ebassi/graphene/pulls)
5. Wait for me to give feedback on the pull request
6. Celebrate when your code gets merged
That's pretty much it.
Please, respect the coding style when writing patches for Graphene. The
coding style can be immediately gleaned from the existing code, but here is
a short version:
* Indentation is made of spaces, and only spaces — **no tabs**
* Each indentation level is 2 spaces
* Curly braces for blocks go on a separate indentation level
* Except for functions
* Do not use curly braces for single-statement blocks
* When declaring or defining a function, arguments go on separate
lines
* When calling a function never break a line between the function
name and the opening parenthesis, and between the opening parenthesis
and the first argument
* Leave a space between functions and parenthesis
A more comprehensive coding style document is available in the `docs`
directory.

# Graphene
### A thin layer of types for graphic libraries
[![Build Status](https://travis-ci.org/ebassi/graphene.svg?branch=master)](https://travis-ci.org/ebassi/graphene)
[![Build status](https://ci.appveyor.com/api/projects/status/pw7o5grgko1l06hd/branch/master?svg=true)](https://ci.appveyor.com/project/ebassi/graphene/branch/master)
When creating graphic libraries you most likely end up dealing with points
and rectangles. If you're particularly unlucky, you may end up dealing
with affine matrices and 2D transformations. If you're writing a graphic
library with 3D transformations, though, you are going to hit the jackpot:
4x4 matrices, projections, transformations, vectors, and quaternions.
Most of this stuff exists, in various forms, in other libraries, but it
has the major drawback of coming along with the rest of those libraries,
which may or may not be what you want. Those libraries are also available
in various languages, as long as those languages are C++; again, it may or
may not be something you want.
For this reason, I decided to write the thinnest, smallest possible layer
needed to write a canvas library; given its relative size, and the
propensity for graphics libraries to have a pun in their name, I decided
to call it Graphene.
This library provides types and their relative API; it does not deal with
windowing system surfaces, drawing, scene graphs, or input. You're
supposed to do that yourself, in your own canvas implementation, which is
the whole point of writing the library in the first place.
### Dependencies
Graphene has little dependencies.
Graphene contains optimizations for speeding up vector operations; those
optimizations are optional, and used only if both Graphene was compiled
with support for them *and* if the system you're running on has them.
Currently, Graphene supports the following platform-specific fast paths:
* Streaming SIMD Extensions (SSE) 2
* ARM NEON
* GCC vector extensions
In the remote case in which none of these optimizations are available,
Graphene will fall back to a naive scalar implementation.
Graphene can, optionally, provide types for integrating with GObject
properties and signals, as well as introspection information for its
use with other languages through introspection-based bindings.
### Installation
In order to build and install Graphene you will need development tools and
the headers of the dependencies. You will also need:
* [meson](http://mesonbuild.com)
* [ninja](https://ninja-build.org/)
Alternatively, you can also use Autotools.
First of all, clone the Git repository:
$ git clone git://github.com/ebassi/graphene
$ cd graphene
Then run:
$ mkdir _build && cd _build
$ meson .. # on Windows, it's "meson.py"
$ ninja test
# ninja install
It is possible, when building Graphene, to disable specific optimizations by
using configuration options:
* `-Denable-sse2=false` - will disable the SSE2 fast paths
* `-Denable-arm-neon=false` - will disable the ARM NEON fast paths
* `-Denable-gcc-vector=false` - will disable the GCC vector intrinsics
If you don't plan on generating introspection data, use `-Denable-introspection=false`
when configuring Graphene; similarly, if you don't plan on using GObject with
Graphene, use `-Denable-gobject-types=false`. Disabling GObject types will also
automatically disable generating introspection data.
You can also disable building the test suite and the benchmark suite, using
the `-Denable-tests=false` and `-Denable-benchmarks=false` configuration switches
respectively.
#### Building on Windows
In order to build on Windows, it's recommended to use the
[MSYS2](http://sourceforge.net/projects/msys2/) environment.
First, [install MSYS2](https://msys2.github.io/) and update it fully
as documented.
Then use `pacman` to set up the build environment by installing the
necessary prerequisites for your target. For all build systems, you
will need a standard development environment and the appropriate native
toolchain. You also need a Python interpreter for introspection builds,
which are the default.
$ pacman -S base-devel
$ pacman -S python3 # for introspection
$ pacman -S mingw-w64-x86_64-toolchain # only MINGW64 target
$ pacman -S mingw-w64-i686-toolchain # only MINGW32 target
If you're using GNU Autotools, you don't need to do anything more.
Autotools is part of the `base-devel` group.
If you want to try Meson, install the appropriate native package:
$ pacman -S mingw-w64-x86_64-meson # only MINGW64 target
$ pacman -S mingw-w64-i686-meson # only MINGW32 target
There are a number of optional dependencies too:
$ pacman -S gtk-doc # optional
$ pacman -S mingw-w64-x86_64-glib2 # optional, MINGW64 target only
$ pacman -S mingw-w64-i686-glib2 # optional, MINGW32 target only
$ pacman -S glib2 glib2-devel # optional, MSYS target only
Then clone the Graphene repository and build as usual by following the
instructions in the section above. If you're using Meson, please note
that the tool may be installed as "meson.py" on MSYS2.

* [spheres](http://ebassi.github.io/graphene/docs/graphene-Sphere.html)
* [frustums](http://ebassi.github.io/graphene/docs/graphene-Frustum.html)
Graphene also provides its low-level SIMD [vector](http://ebassi.github.io/graphene/docs/graphene-SIMD-vector.html)
and [matrix](http://ebassi.github.io/graphene/docs/graphene-SIMD-matrix.html)
types, which are used to implement the API above.
All types can be placed on the stack, but provide allocation/free functions
for working on the heap as well. The contents of all structure types, unless
noted otherwise, should be considered private, and should never be accessed
directly.
The full API reference for Graphene is [available online](http://ebassi.github.io/graphene/docs/).

# Graphene Coding Style
This document is intended to be a short description of the preferred
coding style to be used for the Graphene 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 examples will show the preferred coding style; the negative examples
will be clearly identified. Please, don't submit code to Graphene that
looks like any of these.
Part of the rationales for these coding style rules are available either
in the Linux kernel `CodingStyle` document or in Cairo's `CODING_STYLE`
one.
When in doubt, check the surrounding code and try to imitate it.
### Line width
The maximum line width for source files is 100 characters, whenever possible.
Longer lines are usually an indication that you either need a function
or a pre-processor macro.
### Indentation
Each new level is indented 2 or more spaces than the previous level:
if (condition)
single_statement ();
This can only be achieved using space characters. It may not be achieved
using tab characters alone, or using a combination of spaces and tabs.
Do not change the editor's configuration to change the meaning of a
tab character (see below); code using tabs to indent will not be accepted
into Graphene.
Even if two spaces for each indentation level allows deeper nesting than
8 spaces, Graphene favours self-documenting function names that can take
quite some space. For this reason alone you should avoid deeply nested
code.
### Tab characters
The tab character must always be expanded to spaces. If a literal
tab must be used inside the source, the tab must always be interpreted
according to its traditional meaning:
```
Advance to the next column which is a multiple of 8.
[ these two lines should be aligned ]
```
### Braces
Curly braces should not be used for single statement blocks:
if (condition)
single_statement ();
else
another_single_statement (arg1);
In case of multiple statements, curly braces should be put on another
indentation level:
if (condition)
{
statement_1 ();
statement_2 ();
statement_3 ();
}
The "no block for single statements" rule has only three exceptions:
1. if the single statement covers multiple lines, e.g. for functions with
many arguments, and it is followed by else or else if:
```
/* valid */
if (condition)
{
a_single_statement_with_many_arguments (some_lengthy_argument,
another_lengthy_argument,
and_another_one,
plus_one);
}
else
another_single_statement (arg1, arg2);
```
2. if the condition is composed of many lines:
```
/* valid */
if (condition1 ||
(condition2 && condition3) ||
condition4 ||
(condition5 && (condition6 || condition7)))
{
a_single_statement ();
}
```
3. Nested if's, in which case the block should be placed on the
outermost if:
```
/* valid */
if (condition)
{
if (another_condition)
single_statement ();
else
another_single_statement ();
}
/* invalid */
if (condition)
if (another_condition)
single_statement ();
else if (yet_another_condition)
another_single_statement ();
```
In general, new blocks should be placed on a new indentation level,
like:
int retval = 0;
statement_1 ();
statement_2 ();
{
int var1 = 42;
gboolean res = FALSE;
res = statement_3 (var1);
retval = res ? -1 : 1;
}
While curly braces for function definitions should rest on a new line
they should not add an indentation level:
/* valid */
static void
my_function (int argument)
{
do_my_things ();
}
/* invalid */
static void
my_function (int argument) {
do_my_things ();
}
/* invalid */
static void
my_function (int argument)
{
do_my_things ();
}
Curly braces must not be placed on the same line as a condition:
/* invalid */
if (condition) {
statement_1 ();
statement_2 ();
}
### Conditions
Do not check boolean values for equality:
/* invalid */
if (condition == TRUE)
do_foo ();
/* valid */
if (another_condition)
do_bar ();
Even if C handles NULL equality like a boolean, be explicit:
/* valid */
if (some_pointer == NULL)
do_blah ();
/* invalid */
if (some_other_pointer)
do_blurp ();
In case of conditions split over multiple lines, the logical operators should
always go at the end of the line:
/* invalid */
if (condition1
|| condition2
|| condition3)
{
do_foo ();
}
/* valid */
if (condition1 &&
condition2 &&
(condition3 || (condition4 && condition5)))
{
do_blah ();
}
### Types
All public types in Graphene should conform to the `<namespace>_<type>_t`
pattern, e.g.:
/* valid */
typedef struct _graphene_quaternion_t graphene_quaternion_t;
/* valid */
typedef enum {
...
} graphene_euler_order_t;
/* invalid */
typedef struct _foo_bar_t foo_bar_t;
/* invalid */
typedef enum {
...
} GrapheneBlah;
CamelCase is not allowed in the public API, and it's strongly discouraged
for the internals as well.
All public types should have public structure definitions, but if fields are
to be considered private then you should add them at the end of the
structure definition, and use the `GRAPHENE_PRIVATE_FIELD` macro to declare
them, e.g.:
/* valid */
struct _graphene_euler_t
{
GRAPHENE_PRIVATE_FIELD (graphene_vec3_t, angles);
GRAPHENE_PRIVATE_FIELD (graphene_euler_order_t, order);
};
/* invalid */
struct _graphene_foo_t
{
graphene_vec4_t __some_private_field;
graphene_vec4_t public_field;
};
All public types should have the following functions:
* a `graphene_<type>_alloc()` allocator; the contents of the structure
returned by this function are undefined
* a `graphene_<type>_free()` deallocator; this function should be NULL-safe
* a `graphene_<type>_init()` initializer
All initializer functions should take a pointer of the type they initialize
as their first argument, and return the initialized structure, e.g.:
/* valid */
graphene_rect_t * graphene_rect_init (graphene_rect_t *rect,
float x,
float y,
float width,
float height);
All types should be usable on the stack, after being initialized; the
behaviour of a type before initialization is undefined.
### Functions
Functions should be declared by placing the returned value on a separate
line from the function name:
void
my_function (void)
{
}
The arguments list must be broken into a new line for each argument,
with the argument names right aligned, taking into account pointers:
void
my_function (some_type_t type,
another_type_t *a_pointer,
final_type_t another_type)
{
}
The alignment also holds when invoking a function without breaking the
80 characters limit:
align_function_arguments (first_argument,
second_argument,
third_argument);
To respect the 80 characters limit do not break the function name from
the arguments:
/* invalid */
a_very_long_function_name_with_long_parameters
(argument_the_first, argument_the_second);
/* invalid */
a_very_long_function_name_with_long_parameters (
argument_the_first, argument_the_second);
/* valid */
first_a = argument_the_first;
second_a = argument_the_second;
a_very_long_function_name_with_long_parameters (first_a, second_a);
All public functions must be annotated with the `GRAPHENE_AVAILABLE_IN_x_y`
macro for the `x.y` stable release in which they appear. Functions private
to a specific source file should always be marked as `static`; functions
private to the whole project should be declared in a private header.
### Whitespace
Always put a space before a parenthesis but never after:
/* valid */
if (condition)
do_my_things ();
/* valid */
switch (condition)
{
}
/* invalid */
if(condition)
do_my_things();
/* invalid */
if ( condition )
do_my_things ( );
A `switch()` should open a block on a new indentation level, and each case
should start on the same indentation level as the curly braces, with the
case block on a new indentation level:
/* valid */
switch (condition)
{
case FOO:
do_foo ();
break;
case BAR:
do_bar ();
break;
}
/* invalid */
switch (condition) {
case FOO: do_foo (); break;
case BAR: do_bar (); break;
}
/* invalid */
switch (condition)
{
case FOO: do_foo ();
break;
case BAR: do_bar ();
break;
}
/* invalid */
switch (condition)
{
case FOO:
do_foo ();
break;
case BAR:
do_bar ();
break;
}
It is preferable, though not mandatory, to separate the various cases with
a newline:
switch (condition)
{
case FOO:
do_foo ();
break;
case BAR:
do_bar ();
break;
default:
do_default ();
}
The `break` statement for the `default:` case is not mandatory, but it is
appreciated.
If a case block needs to declare new variables, the same rules as the
inner blocks (see above) apply; the break statement should be placed
outside of the inner block:
switch (condition)
{
case FOO:
{
int foo;
foo = do_foo ();
}
break;
...
}
Do not eliminate whitespace and newlines just because something would
fit in the line character limit:
/* invalid */
if (condition) foo (); else bar ();
Please, eliminate all trailing or leading whitespace before submitting a
patch for review.
### Headers
Headers are special, for Graphene, in that they don't have to obey the
80 characters limit. The only major rule for headers is that the functions
definition should be vertically aligned in three columns:
return value function_name (type argument,
type argument,
type argument);
The maximum width of each column is given by the longest element in the
column:
bool graphene_type_set_property (graphene_type_t *type,
const char *value,
char **out_value);
const char *graphene_type_get_property (graphene_type_t *type);
It is also possible to align the columns to the next tab:
void graphene_type_set_property (graphene_type_t *type,
float value);
float graphene_type_get_property (graphene_type_t *type);
int graphene_type_update_foobar (graphene_type_t *type);
Public headers should have inclusion guards and C++ guards:
#ifndef __GRAPHENE_HEADER_H__
#define __GRAPHENE_HEADER_H__
#if !defined(__GRAPHENE_H_INSIDE__) && !defined(GRAPHENE_COMPILATION)
#error "Only <graphene.h> can be included directly."
#endif
#include "graphene-types.h"
GRAPHENE_BEGIN_DECLS
...
GRAPHENE_END_DECLS
#endif /* __GRAPHENE_HEADER_H__ */
Private headers do not need the single header inclusion guard, but they need
every other guard. Private headers should also be clearly named with a
`-private` suffix. Private headers should include the public header for the
type they relate to, first:
#ifndef __GRAPHENE_FOO_PRIVATE_H__
#define __GRAPHENE_FOO_PRIVATE_H__
#include "graphene-foo.h"
GRAPHENE_BEGIN_DECLS
...
GRAPHENE_END_DECLS
#endif
### Includes
Graphene source files should never include the global `graphene.h` header, but
instead include the individual headers that are needed. Every file must
include `graphene-private.h` first, then its own header, then other Graphene
header in an alphabetical order, then system and third-party headers.
/* valid */
#include "graphene-private.h"
#include "graphene-foo.h"
#include "graphene-box.h"
#include "graphene-point3d.h"
#include "graphene-vec3.h"
...
#include <math.h>
### Macros
Try to avoid private macros unless strictly necessary. Remember to #undef
them at the end of a block or a series of functions needing them.
Inline functions are usually preferable to private macros.
Public macros should not be used unless they evaluate to a constant.
### Documentation
All public APIs must have gtk-doc comments. For functions, these should
be placed in the source file, directly above the function.
/* valid */
/**
* graphene_type_get_property:
* @type: a #graphene_type_t
*
* Gets the property of a #graphene_type_t.
*
* Returns: the value of the property
*/
float
graphene_type_get_property (graphene_type_t *type)
{
...
}
Doc comments for macros, function types, structures, etc should be
placed next to the definitions, typically in headers.
Section introductions should be placed in the source file they describe,
after the license header:
/* valid */
/**
* SECTION:graphene-type
* @Title: Type
* @Short_description: A representation of a type
*
* [...]
*/
To properly document a new function, macro, function type or struct,
it needs to be listed in the graphene-sections.txt file.
To properly document a new type, it needs to be given its own section
in `graphene-sections.txt`, and it needs to be included in `graphene-docs.xml`.
### Old code
It is ok to update the style of a code block or function when you
are touching it anyway, but sweeping whitespace changes obscure the
revision control history and should be avoided at all costs.
