Doesn't handle negative numbers for an arg

[jprichardson]

If you want to have a program that has a negative number for an arg, commander.c causes a segfault.

./myprog --n -5

or...

./myprog -n "-5"

Any thoughts on why?

[jprichardson]

Doesn't actually crash, that's a result of my strtod code trying to convert a null value. But it does print: unrecognized flag -5.

commander interprets it as a flag currently, we could special-case digits, might as well

[chrisledet]

Seems like any value that starts with - is misinterpreted as a flag.

For example, if I pass in "--- No way jose" I get the following message:

unrecognized flag --- No way jose"

I tried wrapping it in quotes but that didn't help. Any way around this?

not currently, but we should support -- for separating args

oh we do :D

./test foo -- --stuff --here
additional args:
  - 'foo'
  - '--stuff'
  - '--here'
