Re: [Dancer-users] Dancer.pm sets confdir too early

No, you can't do that. It has never been possible to set the confdir via
the "set" keyword as Dancer needs to parse configuration files at import
time.
Agreed. I had seen the DANCER_CONFDIR environment variable, but could 
not get it to work from within a Perl script or module (using 
$ENV{DANCER_CONFDIR} = ..) without calling Dancer->import() manually, so 
that defeated the purpose.

I worked around it by doing:

   package MyApp::Portal;
   use Dancer ':syntax';
   set confdir     => MyApp::ConfDir;
   set appdir      => ...

and

   #!/usr/bin/env perl
   use MyApp::Portal;

   use Dancer ':syntax';
   use Dancer::Config;
   use Dancer::GetOpt;

   Dancer::GetOpt->process_args();
   Dancer::Config->load;

   dance;

which mimics import() without forcing the settings.

YMMV. Maybe import() could have a different parameter (besides :syntax), 
for example :nodefaults, which would do:

   unless ($symbol && $symbol eq ':nodefaults') {
     setting appdir => dirname(File::Spec->rel2abs($script));
     # etc.
     setting confdir => $ENV{DANCER_CONFDIR} || setting('appdir');
   }
