jc - JSON Convert lib module
<a id="jc.lib.all_parser_info"></a>
### all_parser_info
```python
def all_parser_info(
documentation: bool = False,
show_hidden: bool = False,
show_deprecated: bool = False) -> List[jc.jc_types.ParserInfoType]
```
Returns a list of dictionaries that includes metadata for all parser
modules. By default only non-hidden, non-deprecated parsers are
returned.
Parameters:
documentation: (boolean) include parser docstrings if True
show_hidden: (boolean) also show parsers marked as hidden
in their info metadata.
show_deprecated: (boolean) also show parsers marked as
deprecated in their info metadata.
<a id="jc.lib.get_help"></a>
### get_help
```python
def get_help(parser_mod_name: Union[str, module]) -> None
```
Show help screen for the selected parser.
This function will accept **module_name**, **cli-name**, and
**--argument-name** variants of the module name string as well as a
parser module object.
<a id="jc.lib.get_parser"></a>
### get_parser
```python
def get_parser(parser_mod_name: Union[str, module]) -> module
```
Return the parser module object and check that the module is a valid
parser module.
Parameters:
parser_mod_name: (string or Name of the parser module. This
Module) function will accept module_name,
cli-name, and --argument-name
variants of the module name.
If a Module is given and the Module
is a valid parser Module, then the
same Module is returned.
Returns:
Module: the parser Module object
Raises:
ModuleNotFoundError: If the Module is not found or is not a valid
parser Module, then a ModuleNotFoundError
exception is raised.
<a id="jc.lib.parse"></a>
### parse
```python
def parse(
parser_mod_name: Union[str, module],
data: Union[str, bytes, Iterable[str]],
quiet: bool = False,
raw: bool = False,
ignore_exceptions: Optional[bool] = None,
**kwargs
) -> Union[Dict[str, Any], List[Dict[str, Any]], Iterator[Dict[str, Any]]]
```
Parse the data (string or bytes) using the supplied parser (string or
module object).
This function provides a high-level API to simplify parser use. This
function will call built-in parsers and custom plugin parsers.
Example (standard parsers):
>>> import jc
>>> date_obj = jc.parse('date', 'Tue Jan 18 10:23:07 PST 2022')
>>> print(f'The year is: {date_obj["year"]}')
The year is: 2022
Example (streaming parsers):
>>> import jc
>>> ping_gen = jc.parse('ping_s', ping_output.splitlines())
>>> for item in ping_gen:
>>> print(f'Response time: {item["time_ms"]} ms')
Response time: 102 ms
Response time: 109 ms
...
To get a list of available parser module names, use `parser_mod_list()`.
Alternatively, a parser module object can be supplied:
>>> import jc
>>> jc_date = jc.get_parser('date')
>>> date_obj = jc.parse(jc_date, 'Tue Jan 18 10:23:07 PST 2022')
>>> print(f'The year is: {date_obj["year"]}')
The year is: 2022
You can also use the parser modules directly via `get_parser()`:
>>> import jc
>>> jc_date = jc.get_parser('date')
>>> date_obj = jc_date.parse('Tue Jan 18 10:23:07 PST 2022')
>>> print(f'The year is: {date_obj["year"]}')
The year is: 2022
Finally, you can access the low-level parser modules manually:
>>> import jc.parsers.date
>>> date_obj = jc.parsers.date.parse('Tue Jan 18 10:23:07 PST 2022')
>>> print(f'The year is: {date_obj["year"]}')
The year is: 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 or name of the parser module. This
Module) function will accept module_name,
cli-name, and --argument-name
variants of the module name.
A Module object can also be passed
directly or via get_parser()
data: (string or data to parse (string or bytes for
bytes or standard parsers, iterable of
iterable) 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_info
```python
def parser_info(parser_mod_name: Union[str, module],
documentation: bool = False) -> jc.jc_types.ParserInfoType
```
Returns a dictionary that includes the parser module metadata.
Parameters:
parser_mod_name: (string or name of the parser module. This
Module) function will accept module_name,
cli-name, and --argument-name
variants of the module name as well
as a parser module object.
documentation: (boolean) include parser docstring if True
<a id="jc.lib.parser_mod_list"></a>
### parser_mod_list
```python
def parser_mod_list(show_hidden: bool = False,
show_deprecated: bool = False) -> List[str]
```
Returns a list of all available parser module names.
<a id="jc.lib.plugin_parser_mod_list"></a>
### plugin_parser_mod_list
```python
def plugin_parser_mod_list(show_hidden: bool = False,
show_deprecated: bool = False) -> List[str]
```
Returns a list of plugin parser module names. This function is a
subset of `parser_mod_list()`.
<a id="jc.lib.slurpable_parser_mod_list"></a>
### slurpable_parser_mod_list
```python
def slurpable_parser_mod_list(show_hidden: bool = False,
show_deprecated: bool = False) -> List[str]
```
Returns a list of slurpable parser module names. This function is a
subset of `parser_mod_list()`.
<a id="jc.lib.standard_parser_mod_list"></a>
### standard_parser_mod_list
```python
def standard_parser_mod_list(show_hidden: bool = False,
show_deprecated: bool = False) -> List[str]
```
Returns a list of standard parser module names. This function is a
subset of `parser_mod_list()` and does not contain any streaming
parsers.
<a id="jc.lib.streaming_parser_mod_list"></a>
### streaming_parser_mod_list
```python
def streaming_parser_mod_list(show_hidden: bool = False,
show_deprecated: bool = False) -> List[str]
```
Returns a list of streaming parser module names. This function is a
subset of `parser_mod_list()`.
