Classes

Param(*, Def: dict = {}, Args: Optional[list] = None, Chk=None, Desc: str = '', AddPar: str = '', AllParams: bool = True, UserPars: Optional[dict] = None, UserModes: Optional[dict] = None, ErrorOnUnknown: bool = True, HelpType: int = 0, Children: dict = {}, translation: dict = {}, Version: str = '', License: Union[str, tuple, list, dict, ForwardRef(None)] = None, ShowPrefixOnHelp: bool = True) : Main class and also the result-dictionary. A member of this class acts like a dictionary. There are some special cases if you use nested childs. (Check out the :doc:usage section for further information)

This is the constructor of the Param-class.

Most of the parameters can be set also later on (if nessasary)

.. note::
    all parameters are only by name and NOT positional!

:param Args: See :func:`SetArgs`, defaults to None
:type Args: Optional[list], optional
:param Chk: See :func:`SetChk`, defaults to None
:type Chk: callable, optional
:param Desc: See :func:`SetDesc`, defaults to ""
:type Desc: str, optional
:param AddPar: See :func:`SetAddPar`, defaults to ""
:type AddPar: str, optional
:param AllParams: See :func:`SetAllParams`, defaults to True
:type AllParams: bool, optional
:param UserPars: See :func:`SetUserKeys`, defaults to None
:type UserPars: Optional[dict], optional
:param UserModes: See :func:`SetUserKeys`, defaults to None
:type UserModes: Optional[dict], optional
:param ErrorOnUnknown: If True an error is raised if
            there are undefined options on the commandline, if False: no error is raised.

            UnusedArgs is always populated with all undefined args from the commandline.
            This error is raised only on the topmost Param-object (not on children)
            Defaults to True.
            So if set to False you can test the 'UnusedArgs' property after return
            of the 'Process'-function to get the list of undefined args and process
            this situation on your own. Defaults to True
:type ErrorOnUnknown: bool, optional
:param HelpType: Type of helptext.

            0: No Type, no standard defaults,
            1: No Type, all defaults,
            2: Type, no standard defaults,
            3: Type and all defaults,

            defaults to 0
:type HelpType: int, optional
:param Children: Dictionary of Child-definition for this class.

        .. code-block:: python

            { 'Name': {'Def': {}, 'Desc': str, 'AddPar': str, 'Children': {} }, .... }

        Name = The name of this child. Must be unique.
                Is translated to lower case.
                Can not be "global" (this is the name of the root-class)

        Def = A definition dictionary like our own "Def" parameter,

        Children (optional) = dict of type Children, describes the grand-childer,
                this can be done to any level.

        Desc (optional) = A string that describes this class
                (like our own "Desc"-parameter).

        AddPar (optional) = String used as additional info
                (like our own "AddPar"-parameter). Defaults to {}

:type Children: dict, optional
:param License: List of license-texts.
            Thie texts are displayed if a '§' or 'L' -type option is applied.
            If '§': only the first entry within this list is displayed,
            if 'L': all entries separated by a newline ('\n') are displayed.
            To help there is a separate module "GPL3" which includes the folowing entries:

                "GPL_Preamble" the suggested preamble (after the copyright notice)

                "GPL_Preamble_DE" the same preamble in German language.

                "LGPL_Preamble" the suggested preamble for the LGPL
                    (use after the copyright notice)

                "LGPL_Preamble_DE" the same preamble in German language.

                "LGPL3_2007" the additional terms of the Lesser GPL Version 3 from
                    June, 29th 2007, you shold append also the following
                    (GPL3_2007) if you use this license.

                "GPL3_2007" the complete text of the GPL Version 3 from June, 29th 2007

            you can use this by

            .. code-block:: python

                from pcs_argpass.GPL3 import GPL_Preamble, LGPL3_2007, GPL3_2007

            and in the constructor of Param par example with:

            .. code-block:: python

                MyParam = Param (
                    ....
                License=('\nCopyright (c) <date> <your name>\n' + GPL_Preamble_DE,
                        GPL_Preamble,
                        LGPL3_2007,
                        GPL3_2007),
                    ....
                    )

            but, of course you can use every other license text you want, as long as this
            license is compatible with the license of this module, whitch IS LGPL3.
:type License: list[str], optional
:param translation: See :func:`SetTranslation`, defaults to {}
:type translation: dict, optional
:param Version: Version string for help-display, defaults to ''
:type Version: str, optional
:param _Child: True if this instance should be a child, defaults to False
:type _Child: bool, optional


.. note::

    All long options can be abbreviated to at least 2 characters or to the
    length making them unique within the defined long options.

    Example:

        you define 'automatic', 'autonom' and 'testopt'
        at the commandline this can be abbreviated to

        .. code-block::

            PROG --autom --auton --te

        but not to

        .. code-block::

            PROG --au

        because this is not unique within the optionlist.

.. note::

    If children are used, the prefix-name is always optional, but if given, the option
    is ONLY recognized for this child. if there are the same long options for more
    then one child and NO prefix is given, this option is recognized by ALL children
    having this long option within their definition.

    Example:

        you define 'auto' within the root as 'MyOpt'
        you define 'auto' within the child 'alpha' as 'DoAuto'

        the commandline should be

        .. code-block::

            PROG --auto=yes

        then BOTH options are set to 'yes' e.g. MyParam['MyOpt'] == 'yes' AND MyParam['DoAuto'] == 'yes'
        with the commandline

        .. code-block::

            PROG --alpha.auto=yes

        only MyParam['DoAuto'] == 'yes' and MyParam['MyOpt'] is either the default or not set depending on
        the definition of this option
        with the commandline

        .. code-block::

            PROG --alpha.auto=yes --global.auto=no

        MyParam['MyOpt'] == 'no' AND MyParam['DoAuto'] == 'yes'
        REMEMBER: 'global' is ALWAYS the name of the root Param-object!

    please inform your users about this possibility if you use child-definitions!

### Class variables

`DeclarationError`
:   this exception is raised if there is an declaration error within the
    parameters of the class.
    
    .. note::
        This error messages are NEVER translated since they are not user
        initiated errors.

`GetoptError`
:   Own error-class for option-errors

`ParamError`
:   This exception is raised if there is an error within the runtime-parameters.
    This is only raised within the :func:`Param.Process`-function.
    
    .. note::
        This errors are translated with the 'translation' dictionary. There
        is the initial state of this dict using 'en_US' texts.
    
        This module also provide a 'Translation_de_DE' entry giving a german
        translation of the error-messages, and a 'Translation_en_US' table only vor completeness.
    
        If you can provide translations to other languages send me this
        declarations to <[e-mail]> and I will add them to this
        module.

    Example:
        root defines '-z'
        child defines '-a'
        commandline is "-a -z --test"
    
        UnusedArgs of child is ['-z','--test']

        ------------------------------------------------------------
        global
        ------------------------------------------------------------
        global                     -> NoDaemon (-d, --[global.]nodaemon)              : False

        gamma  -> Xy        : False
        beta   -> Verbose   : 5
    
        The shortest format is like (recursive = False):
    
        global -> NoDaemon  : False
        global -> Quiet     : False
        global -> StdErr    : False
        global -> Verbose   : 2

    :type AllParams: bool, optional

`SetArgs(self, Args: Union[list, tuple, ForwardRef(None)] = None) ‑> None`
:   Set the argument list to process
    
    :param Args: Runtime Arguments, if None: use sys.argv as the arguments , defaults to None
    :type Args: Optional[Union[list, tuple]], optional
    :raises TypeError: if Args is not a list or tuple

`SetChk(self, Chk=None)`
:   Set the check-function. Not implementet now
    
    :param Chk: The user check function
    :type Chk: callable

    :param Def: A definition-dict. Defaults to {}.
    :type Def: dict, optional
    :raises TypeError: on error within the definition
    
    Describes the definition for arg-parsing.
    
    Def-dict: a dictionary of dictionaries
    
    .. code-block:: python
    
        { 'Name1': {.. declaration ..},
        ...
        'Name2': {.. declaration ..}, }
    
    "NameN" is the key with which, at runtime, you get the values within the resulting dictionary.
    
    The individual definitions look like:
    
    .. code-block:: python
    
        {'s': 'a',
        'l': 'longval',
        'o': True,
        'v': "LuLu",
        'm': 't',
        'd': 'Description',
        'L': 'Low',
        'U': 'Up',
        'r': False },
    
    where:
    
    .. code-block::
    
        m : Mode ->
                't' = Text,
                'b' = Bool,
                'p' = Path,
                'f' = Existing File,
                'd' = Exist. Dir,
                'i' = Integer,
                'F' = Float,
                'C' = Counter (start default as 0 and increment each time found)
                        Special case: short option takes no argument,
                        long option NEEDS argument
                        short option increments the value,
                        long option adds the argument to the value
        The following are processed BEVOR all others:
                'H' = Show help and exit
                '§' = Display short license and exit
                'L' = Display long license and exit
                'x' = Import config-file as json (file must exist like "f")
                            can be given more than once!
                '<' = MultiImport config-file as json
        The following are processed AFTER all others:
                'X' = Export config as json to stdout und exit
                '>' = MultiExport config as json to stdout und exit
        r : Required -> True or False, False is default
        s : Short Option(s) -> string or list or tuple of strings
        l : Long Option(s) -> string or list or tuple of strings
        o : option needs argument -> True oder False, False is default
        v : Default value -> if not given:
                "" for Text,
                False for Bool,
                None for Path, File and Dir,
                0 for Int und Counter,
                0. for Float
                [] for multi-items
        L : Lower Limit, value >= L if present
        U : Upper Limit, value <= U if present
        d : Description for helptext
        M : If True: multiples of this option are accepted.
            the resulting value is a list.
    
    The entries "m" and ("s" or "l") must be present, all others are optional.

`SetDesc(self, Desc: str = '') ‑> None`
:   Set the description of the program for usage-string.
    
    :param Desc: A descriptive string for the Program.
        printed bevore the parameters. Defaults to ''.
    :type Desc: str, optional
    :raises TypeError: if Desc is not a string.

`SetTranslation(self, translation: dict, IsChild: bool = False) ‑> None`
:   Seta net translation-table
    
    :param translation: Dictionary with translated error-messages
    :type translation: dict
    :param IsChild: True if we are the root-parent, defaults to False
    :type IsChild: bool, optional
    
    
    There are 2 'Hidden' function to help debug the translations:
    
        _PrintInitTranslation() and
        _PrintActualTranslation()
    
    Theses functions do exactly what they say: print the values out to stdout. You can
    use them to get the exact values used. The following default may not be accurate
    at all - do not rely on this info, print the dict yourselve.
    
    defaults to:
