Default "--version" option behavior not mentioned
preaction opened this issue · comments
The behavior of the "--version" option does not appear to be mentioned anywhere in the documentation.
Getopt::Long has a default behavior for the --version option that seems useful, but I inadvertently created a "version" option myself and was confused when it got used in my tests (the behavior of the --version option does not work very well under App::Cmd::Tester).
Would it also be a good idea to add a "no_auto_version" option to go with the "no_auto_help" option?
I don't see any default behavior for --version
so I'm not sure what you're seeing. Can you provide a program that shows off something?
~$ dzil --version
Unrecognized command: --version
~$ dzil help --version
Unrecognized command: --version
https://github.com/ChicagoPM/Command-Line-Apps In this repository, the "say.pl" is an App::Cmd application. If I do perl say.pl --version
, I get:
say.pl
(Getopt::Long::GetOptions version 2.38; Perl version 5.12.4)
The Getopt::Long docs say this about it: auto_version will be enabled if the calling program explicitly specified a version number higher than 2.32 in the use or require statement.
, which Getopt::Long::Descriptive does.
Also, for some reason, when I do dzil --version
, I get:
/Users/doug/perl5/bin/dzil version 4.300028
(Getopt::Long::GetOptions version 2.38; Perl version 5.12.4)
... And now that I've updated Getopt::Long to 2.40 from CPAN, I get what you get, which just leaves me confused... But that solves this issue, I guess!
