Feature #12459

Updated by nobu (Nobuyoshi Nakada) about 4 years ago

I suggest a little new feature to lib/optparse.rb. 

 When I created CLI tool I defined option parser with `ARGV.getopts` ARGV.getopts function like following. 

 ~~~ruby ~~~ 
 ARGV.getopts('abc:', 'logopt, 'optwithval:val') 
 ~~~ 

 It was so easy and short to recognize what is declared as options, but I could't force a type of the values. 
 Maybe it looks unshapely, but I'd like to confirm the types like this: 

 ~~~ruby ~~~ 
 ARGV.getopts('strval:(String)intval:(Integer)', 'logopt', 'logopt, 'optwithval:val(String)') 
 ~~~ 

 Normal OptParser has type coercion but extended function `ARGV.getopts` ARGV.getopts has no feature like this. 
 This difference is trivial but inconvenient.
