NAME

       Catmandu::Fix::Datahub - Utility functions and generic fixes developed for the Datahub project

SYNOPSIS

         use Catmandu::Fix::Datahub::Util;

DESCRIPTION

         use Catmandu::Fix::Datahub::Util;

       "declare_source($fixer, $var, $declared_var)"
           For  an  item  $var, which is a path (as a string) in a Catmandu fix, assign the value at the path to
           $declared_var, which is a variable that was previously declared in the fix code:

             my $f_var = $self->fixer->generate_var();
             $code .= "my ${f_var};";
             $code .= declare_source($self->fixer, 'foo.bar', $f_var);

       "walk($fixer, $path, $key, $h)"
           Walk through a $path (as an arrayref) until at $key. Assign the value of $key  to  $h.   $h  must  be
           declared in the fix code.

             my $f_var = $self->fixer->generate_var();
             $code .= "my ${f_var};";
             $code .= walk($self->fixer, ['foo', 'bar'], $f_var);
