Question

I have 10 Ruby function calls I’d like to execute and each call could possibly throw an exception. I’d like to handle each exception the same way and continue. Is there a way to do this without wrapping each line in a begin … rescue … end block?

[Edit]: Use case for this is a screen scraper/automation tool that uses the Selenium web driver to fill out forms. I don’t want to bother checking if options in select elements exist, just fill them out as good as possible. for this, I need to call Selenium::WebDriver::Support::Select.select_by and continue if it throws a “cannot locate option with value x” exception.

Answer 1

You mean something like this ?

class Wtf
  def f1
    raise "f1"
  end
  def f2
    raise "f2"
  end
end

obj= Wtf.new

[:f1, :f2].each do |f|
  begin
    obj.send f
  rescue Exception=> e
    p e
  end
end

Edit: added more code to the example
