[ruby-core:87371] [Ruby trunk Misc#14812][Closed] Question: Option Parser

Issue #14812 has been updated by nobu (Nobuyoshi Nakada).

Status changed from Open to Closed

Just `rescue OptionParser::InvalidOption`.
As it can't tell if an unknown option has its argument or not, I didn't add such methods.

```ruby
require 'optparse'

unknown = []
ARGV.options do |opt|
  opt.on("--foo=FOO") {|v| @foo = v}
  begin
    opt.order! {|arg| unknown << arg}
  rescue OptionParser::InvalidOption => e
    unknown.concat(e.args)
    redo
  end
end

p unknown
p @foo
```

Hi,

Is there an option / way to ignore undeclared options and get them in a resultset so, I can handle them in a custom way?

Example scenario: Program A redirects unsupported arguments to another Program B called from inside program A.


Thanks.
