find executables on windows

[Ara.T.Howard]

in linux i'd do something (un-tested) like:

def find_bin bin
bin = nil
path = ENV['PATH'].split File:ATH_SEPARATOR
path.each do |dir|
b = File::join dir, bin
return b if File::executable? b
end
bin
end

what would the equivalient be in windows? should the above work or do i need
to check some other env vars?

cheers.

That's the only env var. There's no executable flag, though, and I don't
know what File::executable? does on Windows. I'd try exist? - and you'll
need to append the suffixes in ENV['PATHEXT']. (.com, .exe, .bat, .cmd,
maybe more like .js and .rb)

Cheers,
Dave

See find_executable in lib/mkmf.rb.

10 minutes to wait for an answer and it's already written - i don't know what
i'm paying for! ;-)

cheers.
