configargparse.YAMLConfigFileParser

class documentation

class YAMLConfigFileParser(ConfigFileParser): (source)

Parses YAML config files. Depends on the PyYAML module. https://pypi.python.org/pypi/PyYAML

Method	`get_syntax_description`	Returns a string describing the config file syntax.
Method	`parse`	Parses the keys and values from a config file.
Method	`serialize`	Does the inverse of config parsing by taking parsed values and converting them back to a string representing config file contents.
Method	`_load_yaml`	lazy-import PyYAML so that configargparse doesn't have to depend on it unless this parser is used.

def get_syntax_description(self): (source) ¶

overrides configargparse.ConfigFileParser.get_syntax_description

Returns a string describing the config file syntax.

def parse(self, stream): (source) ¶

overrides configargparse.ConfigFileParser.parse

Parses the keys and values from a config file.

NOTE: For keys that were specified to configargparse as action="store_true" or "store_false", the config file value must be one of: "yes", "no", "on", "off", "true", "false". Otherwise an error will be raised.

Parameters
stream:`io.IOBase`	A config file input stream (such as an open file object).
Returns
`OrderedDict`	Items where the keys are strings and the values are either strings or lists (eg. to support config file formats like YAML which allow lists).

def serialize(self, items, default_flow_style=False): (source) ¶

overrides configargparse.ConfigFileParser.serialize

Does the inverse of config parsing by taking parsed values and converting them back to a string representing config file contents.

Parameters
items	an OrderedDict of items to be converted to the config file format. Keys should be strings, and values should be either strings or lists.
default_flow_style	Undocumented
Returns
Contents of config file as a string

def _load_yaml(self): (source) ¶

lazy-import PyYAML so that configargparse doesn't have to depend on it unless this parser is used.
