nicos-quickyaml

This is a fast dumper for a subset of YAML that NICOS uses for writing data files.

Prerequisites

The module requires Python (2.7 or 3.4+) and numpy (1.6+). The test suite requires nose for running, PyYAML for verification.

Install with setup.py as usual.

Basic usage:

import quickyaml
quickyaml.Dumper(**kwargs).dump(object, stream)

To dump lists as flowing sequences, use the quickyaml.flowlist type, which is a subclass of list.

Dumper keyword arguments:

indent - indent width, default 4
width - fill width for flow sequences
callback - a callable that is called for objects of unsupported types: it takes the object as an argument and must return a bytes object or raise an exception

Run tests with nosetests after setup.py build.
