The OS gem allows for some easy telling if you're on windows or not.
require 'os' >> OS.windows? => true # or OS.doze? >> OS.bits => 32 >> OS.java? => true # if you're running in jruby. Also OS.jruby? >> OS.ruby_bin => "c:\ruby18\bin\ruby.exe" # or "/usr/local/bin/ruby" or what not >> OS.posix? => false # true for linux, os x, cygwin >> OS.mac? # or OS.osx? or OS.x? => false >> OS.dev_null => "NUL" # or "/dev/null" depending on which platform >> OS.rss_bytes => 12300033 # number of rss bytes this process is using currently. Basically "total in memory footprint" (doesn't include RAM used by the process that's in swap/page file) >> puts OS.report ==> # a yaml report of helpful values --- arch: x86_64-darwin10.6.0 target_os: darwin10.6.0 target_vendor: apple target_cpu: x86_64 target: x86_64-apple-darwin10.6.0 host_os: darwin10.6.0 host_vendor: apple host_cpu: i386 host: i386-apple-darwin10.6.0 RUBY_PLATFORM: x86_64-darwin10.6.0 >> OS.cpu_count => 2 # number of cores, doesn't include hyper-threaded cores. >> OS.open_file_command => "start" # or open on mac, or xdg-open on linux (all designed to open a file) >> OS::Underlying.windows? => true # true for cygwin or MRI, whereas OS.windows? is false for cygwin >> OS::Underlying.bsd? => true # true for OS X
If there are any other features you'd like, let me know, I'll do what I can to add them :)

Gem::Platform.local Gem.ruby The reason Gem::Platform.local felt wrong to me is that it treated cygwin as windows--which for most build environments, is wrong. Hence the creation of this gem.
the facets gem (has a class similar to rubygems, above)
require 'facets/platform' Platform.local
the “platform” gem, itself (a different gem)
