Here's my proposal for how we recognize platforms. From
Config::CONFIG, take the target_os and run it through a case
statement to figure out OS and OS version (if any). Combine the
target_cpu, OS and OS version. This value is your platform.
There will be a rubygems-platforms.gem much like sources.gem that can
be updated as-necessary.
Using the tattle data, I came up with this implementation:
def match(cpu, os)
os = case os
when /cygwin/ then [ 'cygwin', nil ]
when /darwin(\d+)?/ then [ 'darwin', $1 ]
when /freebsd(\d+)/ then [ 'freebsd', $1 ]
when /^java([\d.]*)/ then [ 'java', $1 ]
when /linux/ then [ 'linux', $1 ]
when /mingw32/ then [ 'mingw32', nil ]
when /mswin32/ then [ 'mswin32', nil ]
when /openbsd(\d+)/ then [ 'openbsd', $1 ]
when /solaris(\d+\.\d+)/ then [ 'solaris', $1 ]
else [ 'unknown', nil ]
end
[cpu, os].flatten.compact.join("-")
end
require 'rbconfig'
target_cpu = Config::CONFIG['target_cpu']
target_os = Config::CONFIG['target_os']
puts "Your target_cpu is: #{target_cpu.inspect}"
puts "Your target_os is: #{target_os.inspect}"
puts "Your platform is: #{match(target_cpu, target_os).inspect}"
This code recognizes 26 unique platforms:
amd64-freebsd-6
java
java-1.4
powerpc-darwin-7
powerpc-darwin-8
powerpc-darwin-9
powerpc-linux
powerpc64-linux
sparc-solaris-2.10
sparc-solaris-2.8
sparc-solaris-2.9
x86-cygwin
x86-darwin
x86-darwin-8
x86-freebsd-4
x86-freebsd-5
x86-freebsd-6
x86-linux
x86-mingw32
x86-mswin32
x86-openbsd-4
x86-solaris-2.10
x86-solaris-2.8
x86_64-linux
x86_64-openbsd-3
x86_64-openbsd-4
Don't worry about legacy platforms, that's an entirely separate problem.
