# FFI SDL TTF Bindings
A SDL_ttf extension FFI bindings for the PHP language compatible with [SDL FFI bindings for the PHP language](https://github.com/SerafimArts/ffi-sdl).
- [System Requirements](#requirements)
- [Installation](#installation)
- [Documentation](#documentation)
- [Initialization](#initialization)
- [Example](#example)
## Requirements
- PHP ^8.1
- ext-ffi
- Windows, Linux, BSD or MacOS
- Android, iOS or something else are not supported yet
- SDL and SDL TTF >= 2.0
## Installation
Library is available as composer repository and can be
installed using the following command in a root of your project.
```bash
$ composer require serafim/ffi-sdl-ttf
```
Additional dependencies:
- Debian-based Linux: `sudo apt install libsdl2-ttf-2.0-0 -y`
- MacOS: `brew install sdl2_ttf`
- Window: Can be [downloaded from here](https://github.com/libsdl-org/SDL_ttf/releases)
## Documentation
The library API completely supports and repeats the analogue in the C language.
- [SDL2 TTF official documentation](https://www.libsdl.org/projects/SDL_ttf/docs/index.html)
## Initialization
In the case that you need a specific SDL instance, it should be passed
explicitly:
```php
$sdl = new Serafim\SDL\SDL(version: '2.28.3');
$ttf = new Serafim\SDL\TTF\TTF(sdl: $sdl);
// If no argument is passed, the latest initialized
// version will be used.
$ttf = new Serafim\SDL\TTF\TTF(sdl: null);
```
> ! It is recommended to always specify the SDL dependency explicitly.
To specify a library pathname explicitly, you can add the `library` argument to
the `Serafim\SDL\TTF\TTF` constructor.
> By default, the library will try to resolve the binary's pathname automatically.
```php
// Load library from pathname (it may be relative or part of system-dependent path)
$ttf = new Serafim\SDL\TTF\TTF(library: __DIR__ . '/path/to/library.so');
// Try to automatically resolve library's pathname
$ttf = new Serafim\SDL\TTF\TTF(library: null);
```
You can also specify the library version explicitly. Depending on this version,
the corresponding functions of the SDL Image will be available.
> By default, the library will try to resolve SDL Image version automatically.
```php
// Use v2.0.14 from string
$ttf = new Serafim\SDL\TTF\TTF(version: '2.0.14');
// Use v2.20.2 from predefined versions constant
$ttf = new Serafim\SDL\TTF\TTF(version: \Serafim\SDL\TTF\Version::V2_20_2);
// Use latest supported version
$ttf = new Serafim\SDL\TTF\TTF(version: \Serafim\SDL\TTF\Version::LATEST);
```
To speed up the header compiler, you can use any PSR-16 compatible cache driver.
```php
$ttf = new Serafim\SDL\TTF\TTF(cache: new Psr16Cache(...));
```
In addition, you can control other preprocessor directives explicitly:
```php
$pre = new \FFI\Preprocessor\Preprocessor();
$pre->define('true', 'false'); // happy debugging!
$ttf = new Serafim\SDL\TTF\TTF(pre: $pre);
```
## Example
```php
use Serafim\SDL\SDL;
use Serafim\SDL\TTF\TTF;
$sdl = new SDL();
$ttf = new TTF(sdl: $sdl);
$sdl->SDL_Init(SDL::SDL_INIT_EVERYTHING);
$ttf->TTF_Init();
$font = $ttf->TTF_OpenFont(__DIR__ . '/path/to/font.ttf', 42);
echo 'Hinting: ' . $ttf->TTF_GetFontHinting($font) . "\n";
echo 'Kerning: ' . $ttf->TTF_GetFontKerning($font) . "\n";
echo 'Style: ' . match($ttf->TTF_GetFontStyle($font)) {
TTF::TTF_STYLE_NORMAL => 'normal',
TTF::TTF_STYLE_BOLD => 'bold',
TTF::TTF_STYLE_ITALIC => 'italic',
TTF::TTF_STYLE_UNDERLINE => 'underline',
TTF::TTF_STYLE_STRIKETHROUGH => 'strikethrough',
} . "\n";
$color = $sdl->new('SDL_Color');
$color->r = 120;
$color->g = 100;
$color->b = 80;
$surface = $ttf->TTF_RenderText_Solid($font, 'Hello World!', $color);
$ttf->TTF_Quit();
$sdl->SDL_Quit();
```
