What is the correct way to parse an argument with value -

[tevoinea]

I have a program that I would like to execute like so:

./myprogram --someArg 2 --thisFails - --anotherArg 3

Where the value of thisFails should be set to -

I've also tried: "-" to no avail

The error I'm getting is:

ERROR(S):
  Option 'thisFails' has no value.

Use triple quote to quote "-" in the commandline, , then it will passed to the parser with Single Quote:

--somearg 2 --thisfails """-""" --anotherarg 3

[tevoinea]

In my testing, the triple quote returned a value of "-" not - but that's ok, we can work around that.

Thanks!

To avoid tripple quote, merging options with single dash as a value is allowed:

./myprogram --someArg 2 --thisSuccess=- --anotherArg 3  #merge longname with dash using '=' e.g `--thisSuccess=-`
./myprogram --someArg 2   -s- --anotherArg 3  #merge shortname with dash: `-s-`

Single dash will be considered as a value in the next release
