Function request

[ougx]

Hi this is a great addon for Fortran programmer. I am hoping it can be even further enhanced/

1. allow multiple arguments after a switch:
   myapp --range 1.0 2.0 or myapp -r 1.0 2.0
   This can be achieved by adding another parameter in the option_s struct such as nopts. Default can be nopts == 0 for no argument.
2. allow repeating switch:
   myapp --add file1 --add file2 and provide the occurrence of add

Are these implemented? If not, can you implement them? If you do not have time, I can help implement these through a pull request.

Thank you so much!

some thing very interesting:

using ifort on windows, it will stop after paring the first option using the example

however, it runs fine, if you change the sample by calling the function outside the case selection. gfortran does not have this issue.

    do
        a = getopt("ab:h", opts)
        select case(a)
            case(char(0)) ! When all options are processed
                exit
            case("a")
                print*, "option alpha/a"
            case("b")
                print*, "option beta/b=",  trim(optarg) ! "trim" is quite useful to avoid trailing blanks
            case("h")
                print*, "help-screen"
        end select
    end do

No, not at the moment.

Feel free to do so. Thanks, Hani
