Ruby Inline is a framework for writing ruby extensions in foreign languages.
require 'inline' class MyClass inline do |builder| builder.include "<math.h>" builder.c %q{ long factorial(int max) { int i=max, result=1; while (i >= 2) { result *= i--; } return result; } } end end
Inline allows you to write foreign code within your ruby code. It automatically determines if the code in question has changed and builds it only when necessary. The extensions are then automatically loaded into the class/module that defines it.
You can even write extra builders that will allow you to write inlined code in any language. Use Inline::C as a template and look at Module#inline for the required API.
To package your binaries into a gem, use hoe‘s INLINE and FORCE_PLATFORM env vars.
Example:
rake package INLINE=1
or:
rake package INLINE=1 FORCE_PLATFORM=mswin32
See hoe for more details.
rootdir can be forced using INLINEDIR variable if not defined, it should store in user HOME folder
Under Windows user data can be stored in several locations:
HOME HOMEDRIVE + HOMEPATH APPDATA USERPROFILE
Perform a check in that other to see if the environment is defined and if so, use it. only try this on Windows.
