The entry point into Launchy. This is the sole supported public API.
Launchy.open( uri, options = {} )
The currently defined global options are:
:debug Turn on debugging output :application Explicitly state what application class is going to be used :host_os Explicitly state what host operating system to pretend to be :ruby_engine Explicitly state what ruby engine to pretend to be under :dry_run Do nothing and print the command that would be executed on $stdout
Other options may be used, and those will be passed directly to the application class
# File lib/launchy.rb, line 71 def application @application || ENV['LAUNCHY_APPLICATION'] end
# File lib/launchy.rb, line 67 def application=( app ) @application = app end
# File lib/launchy.rb, line 99 def bug_report_message "Please rerun with environment variable LAUNCHY_DEBUG=true or the '-d' commandline option and file a bug at https://github.com/copiousfreetime/launchy/issues/new" end

we may do logging before a call to ‘open’, hence the need to check LAUNCHY_DEBUG here
