NAME

       Catmandu::Fix::Bind::importer - a binder runs fixes on records from an importer

SYNOPSIS

           #
           catmandu run myfix.fix

           # with myfix.fix
           do importer(OAI,url: "http://lib.ugent.be/oai")
             retain(_id)
             add_to_exporter(.,YAML)
           end

           # Or in an runnable Fix script:

           #!/usr/bin/env catmandu run
           add_field(hello,world)
           add_to_exporter(.,YAML)

           # Or:

           #!/usr/bin/env catmandu run
           do importer(OAI,url: "http://lib.ugent.be/oai")
             retain(_id)
             add_to_exporter(.,YAML)
           end

DESCRIPTION

       The import binder computes all the Fix function on records read from the given importer.
       This importer doesn't change the current importer to the given one! Use the 'catmandu run'
       command line command to control importers solely by the Fix script.

CONFIGURATION

   importer(IMPORTER_NAME, step: true|false, IMPORTER_ARGS...)
       Load the import IMPORTER_NAME in the current context. When step is 'true' then for every
       execution of do importer() only one item will be read from the importer. This latter
       option can become handy in nested iterators:

           # This will produce:
           #  {"n":0}
           #  {"m":0}
           #  {"n":1}
           #  {"m":1}
           #  {"n":2}
           #  {"m":2}
           # ...
           do importer(Mock,size:20)
               move_field(n,brol)
               add_to_exporter(.,JSON)

               do importer(Mock,size:20,step:true)
                   move_field(n,m)
                   add_to_exporter(.,JSON)
               end
           end
