Ruby/SDL 2.2.0 Ohbayashi Ippei

= What's Ruby/SDL

Ruby/SDL is the ruby extension library to use SDL. SDL(Simple DirectMedia Layer) is a cross-platform multimedia library
designed to provide fast access to the graphics framebuffer and audio
devices. See http://www.libsdl.org/ if you want to know SDL in detail.

= Platform This library supports Linux, Win32, MacOS X.

This library perhaps works on FreeBSD and other standard Unix-like systems.

= Library Needed

Ruby/SDL needs Ruby and SDL and optionally uses SDL_image, SDL_mixer, SDL_ttf, SGE, OpenGL and SMPEG.

Indispensable Ruby http://www.ruby-lang.org/ SDL http://www.libsdl.org/

Optional SDL_mixer http://www.libsdl.org/projects/SDL_mixer/index.html SDL_ttf http://www.libsdl.org/projects/SDL_ttf/index.html SDL_image http://www.libsdl.org/projects/SDL_image/index.html SGE http://www.etek.chalmers.se/~e8cal1/sge/ SMPEG http://www.icculus.org/smpeg/ SDLSKK http://www.kmc.gr.jp/~ohai/sdlskk.en.html

= INSTALL

Some packages are available: Debian's .deb, FreeBSD's ports, or Windows' zipfile.

RubyGems are also available. You can install Ruby/SDL: gem install rubysdl

You can install from source code as follows: (1)install Ruby See Ruby's document and install.

(2)install SDL Extract SDL's source and run './configure'. And run 'make','make install'.

(3)install SGE Run 'make' and 'make install'.

(4)install SDL_mixer, SDL_ttf, SDL_image, SMPEG and SDLSKK See documents of these libraries and install them .

(5)install this extension library,Ruby/SDL Run 'ruby extconf.rb','make' and 'make install'.

(6) (Mac OS X user only) install rsdl Run 'gem install rsdl'. rsdl is a wrapper of the Ruby interpreter. This wrapper prepares Cocoa framework before running the interpreter.

= Use SGE without installing the library You can use SGE without intalling: gem install rubysdl -- --enable-bundled-sge or ruby extconf.rb --enable-bundled-sge

However, please do not use this option if you have other way. Please install SGE separately if possible.

= USE Ruby/SDL Write "require 'sdl'" in your Ruby script. If your system is OS X, you must use rsdl command as an interpreter instead of ruby command.

See following documents and samples if you want to know the detail.

sample/*.rb Ruby/SDL samples. In some scripts, you have to prepare data such as "sample.wav" and "sample.mpg". rubysdl_ref.en.html The reference manual rubysdl_ref.en.rd RD style reference manual(the contents is same as rubysdl_ref.en.html) documents of SDL This is in SDL archive. Please read this when you want to know what does't describe these documents.

= OpenGL You can use OpenGL with this library.

(1) Setup OpenGL and SDL. (2) Install ruby-opengl (http://ruby-opengl.rubyforge.org/) (3) Run "ruby extconf.rb", "make", and "make install" (4) Write "require 'sdl'; require 'opengl'" in your script.

We use OpenGL through ruby-opengl. Please see SDL's document,OpenGL document and sample/testgl.rb .

= LICENSE This library is distributed under GNU LGPL version 2.1 or later, which can be found in the file "LICENSE". But samples, the Ruby scripts sample/*.rb, are not under LGPL, and you can use their files freely.
