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);
