Fixed-width reader

Agate contains a fixed-width file reader that is designed to work like Python’s csv.

These readers work with CSV-formatted schemas, such as those maintained at wireservice/ffs.

agate.fixed.reader	A wrapper around fixed.Reader, so that it can be used in the same way as a normal CSV reader.
agate.fixed.Reader	Reads a fixed-width file using a column schema in CSV format.
agate.fixed.DictReader	A fixed-width reader that returns collections.OrderedDict rather than a list.

Detailed list

agate.fixed.reader(*args, **kwargs)

A wrapper around fixed.Reader, so that it can be used in the same way as a normal CSV reader.

class agate.fixed.Reader(f, schema_f)

Bases: six.Iterator

Reads a fixed-width file using a column schema in CSV format.

This works almost exactly like Python’s built-in CSV reader.

Schemas must be in the “ffs” format, with column, start, and length columns. There is a repository of such schemas maintained at wireservice/ffs.

fieldnames

The names of the columns read from the schema.

class agate.fixed.DictReader(f, schema_f)

Bases: agate.fixed.Reader

A fixed-width reader that returns collections.OrderedDict rather than a list.
