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
