Hi,
I know, I'm slow, but I finally figured out the minimalistic
command line options parsing that zenspider et al use in utilities
like flog and sow (the gem skeleton generator that comes with Hoe).
Consider, for example,
#!/usr/bin/env ruby -s
$r ||= false
if defined? $h then
puts "usage: #{File.basename $0}"
puts " -h this usage message"
puts " -r recursive"
end
puts "Recursive option: #$r"
The secret sauce is the '-s' option passed to the interpreter,
which according to the PickAxe indicates, "Any command-line switches
found after the program filename, but before any filename arguments
or before a --, are removed from ARGV and set to a global variable
named for the switch."
