getopts

A Odin command line argument parser, loosely based on the getopts_long.

Usage

Checking the test.odin file is probably the easiest way to see how it works in action!

Init and Deinit the Options pointer.

Add arguments as required

getopt_long() will then parse the args into the options pointer. It will parse the following formats:

• -f
• -f 1
• --flag
• --flag value
• --flag=value
• -flag value
• -flag=value

Example:

opts := init_opts()
defer deinit_opts(&opts)
{ // Scoping for easy scope of using.
  using optarg_opt
  add_arg(&opts, "flag", .NO_ARGUMENT)
  add_arg(&opts, "opt-argument", .OPTIONAL_ARGUMENT)
  add_arg(&opts, "required", .REQUIRED_ARGUMENT)
  add_arg(&opts, "h", .NO_ARGUMENT, "help") // Alternative name // long_opt
  add_arg(&opts, "m", .OPTIONAL_ARGUMENT, "my_flag_here")

}
getopt_long(os.args, &opts)
// Parse opts:
for opt in opts.opts {
  if ! opt.set do continue // allows to skip non set options.
  switch opt.name { // name will always be set, don't have to check both
    case "flag":
      // Something
    case "required":
      // Something else 
    case:
      // default? Usage!
  }  
}
