[prosEO CLI] Typing "-v" is executed without result or error message about proseo

[tangobravo62]

Typing "-v" or "--version" now shows the version information:

prosEO> -v
prosEO Command Line Interface (v0.1.0)
prosEO> --version
prosEO Command Line Interface (v0.1.0)

However, this is not syntactically correct (strictly speaking), "-v" is just meant as a program invocation parameter, not as a standalone command.

TODO: Make "-v", "--version", "-h" and "--help" illegal as standalone commands.

In the latest version of the command line interface this is the output:
prosEO> -v
(E2912) Option -v not allowed for command proseo

As such, it is completed as per the "TODO" from the previous comment.

On the other hand, "-h" and "--help" still function.

--version is also functioning but it might be a helpful for the users of prosEO, e.g. in case of a bug the users can easily find which version they are using. Can it be added as a feature?

[tangobravo62]

Note that the option for showing the version has changed to uppercase V:

prosEO (PTM)> -v
(E2912) Option -v not allowed for command proseo
prosEO (PTM)> -V
prosEO Command Line Interface (v0.1.0)
prosEO (PTM)> --version
prosEO Command Line Interface (v0.1.0)

In line with the comment above by dlr-tangosierra the standalone options -V, --version, -h and --help remain valid inputs, although not strictly covered by the command syntax (note however that calling e. g. <prosEO executable> --version on the shell command line is officially supported).
