Platform is a simple module which parses the Ruby constant RUBY_PLATFORM and works out the OS, it‘s implementation, and the architecture it‘s running on.
The motivation for writing this was coming across a case where
+if RUBY_PLATFORM =~ /win/+
didn‘t behave as expected (i.e. on powerpc-darwin-8.1.0)
It is hoped that providing a library for parsing the platform means that we can cover all the cases and have something which works reliably 99% of the time.
Please report any anomalies or new combinations to the author(s).
require "platform"
defines
Platform::OS (:unix,:win32,:vms,:os2) Platform::IMPL (:macosx,:linux,:mswin) Platform::ARCH (:powerpc,:x86,:alpha)
if an unknown configuration is encountered any (or all) of these constant may have the value :unknown.
To display the combination for your setup run
ruby platform.rb
PLATFORMS | = | [ [ /darwin/i, :unix, :macosx ], [ /linux/i, :unix, :linux ], [ /freebsd/i, :unix, :freebsd ], [ /netbsd/i, :unix, :netbsd ], [ /mswin/i, :win32, :mswin ], [ /cygwin/i, :hybrid, :cygwin ], [ /mingw/i, :win32, :mingw ], [ /bccwin/i, :win32, :bccwin ], [ /wince/i, :win32, :wince ], [ /vms/i, :vms, :vms ], [ /os2/i, :os2, :os2 ], [ /solaris/i, :unix, :solaris ], [ /irix/i, :unix, :irix ], [ /.*/, :unknown, :unknown ] |
Each platform is defined as [ /regex/, ::OS, ::IMPL ] define them from most
to least specific and
whither AIX, SOLARIS, and the other unixen? |
