Subject: Treat some command-line argument as option
Download (untitled) / with headers
text/plain 796b
I have a homebrewn command line processing module with this feature (which I plan to incorporate Config::Tree::CmdLine): interpret some command line argument as options. Example syntax in App::Options: use App::Options ( option => { src => { ..., required=>1, cmdline_arg_order => 0 }, dest => { ..., required=>1, cmdline_arg_order => 1 }, foo => { ..., required=>0, } ... } ); This way, beside the usual: script.pl --src=SRC --dest=DEST [--foo=...] I can also write: script.pl SRC DEST [--foo=...] which is shorter. This is nice since I tend to not use @ARGV and have everything as options (because of "free" validation and documentation in the option specification). You might want to consider adding something like this. Regards, Steven

Hi, That is a reasonable suggestion, but I would only allow the positional params to occur AFTER all options. That is the Unix way of doing command line options. Would that remove its usefulness to you? Stephen On Wed, Aug 25, 2010 at 9:13 PM, steven haryanto via RT < bug-App-Options@rt.cpan.org> wrote: Show quoted text

Not really, I tend to specify options before all positional params anyway, but btw in my module I enable/disable this behaviour (per some flag). Steven On Wed Aug 25 23:07:14 2010, SPADKINS wrote: Show quoted text
