jc - JSON CLI output utility JC lib module

parse

def parse(parser_mod_name: str, data: Union[str, Iterable[str]], quiet: Optional[bool] = False, raw: Optional[bool] = False, ignore_exceptions: Optional[Union[None, bool]] = None, **kwargs: Any, ,) -> Union[Dict[str, Any],
                     List[Dict[str, Any]],
                     Iterator[Dict[str, Any]]]

Parse the string data using the supplied parser module.

This function provides a high-level API to simplify parser use. This function will call built-in parsers and custom plugin parsers.

Example:

>>> import jc
>>> jc.parse('date', 'Tue Jan 18 10:23:07 PST 2022')
{'year': 2022, 'month': 'Jan', 'month_num': 1, 'day'...}

To get a list of available parser module names, use parser_mod_list() or plugin_parser_mod_list(). plugin_parser_mod_list() is a subset of parser_mod_list().

You can also use the lower-level parser modules directly:

>>> import jc.parsers.date
>>> jc.parsers.date.parse('Tue Jan 18 10:23:07 PST 2022')

Though, accessing plugin parsers directly is a bit more cumbersome, so this higher-level API is recommended. Here is how you can access plugin parsers without this API:

>>> import os
>>> import sys
>>> import jc.appdirs
>>> data_dir = jc.appdirs.user_data_dir('jc', 'jc')
>>> local_parsers_dir = os.path.join(data_dir, 'jcparsers')
>>> sys.path.append(local_parsers_dir)
>>> import my_custom_parser
>>> my_custom_parser.parse('command_data')

Parameters:

parser_mod_name:    (string)     name of the parser module. This
                                 function will accept module_name,
                                 cli-name, and --argument-name
                                 variants of the module name.

data:               (string or   data to parse (string for normal
                    iterator)    parsers, iterator of strings for
                                 streaming parsers)

raw:                (boolean)    output preprocessed JSON if True

quiet:              (boolean)    suppress warning messages if True

ignore_exceptions:  (boolean)    ignore parsing exceptions if True
                                 (streaming parsers only)

Returns:

Standard Parsers:   Dictionary or List of Dictionaries
Streaming Parsers:  Generator Object containing Dictionaries

parser_mod_list

def parser_mod_list() -> List[str]

Returns a list of all available parser module names.

plugin_parser_mod_list

def plugin_parser_mod_list() -> List[str]

Returns a list of plugin parser module names. This function is a subset of parser_mod_list().

parser_info

def parser_info(parser_mod_name: str) -> Dict[str, Any]

Returns a dictionary that includes the module metadata.

This function will accept module_name, cli-name, and --argument-name variants of the module name string.

get_help

def get_help(parser_mod_name: str) -> None

Show help screen for the selected parser.
