"""
    ScriptForge libraries are an extensible and robust collection of macro scripting resources for LibreOffice
    to be invoked from user Basic or Python macros. Users familiar with other BASIC macro variants often face hard
    times to dig into the extensive LibreOffice Application Programming Interface even for the simplest operations.
    By collecting most-demanded document operations in a set of easy to use, easy to read routines, users can now
    program document macros with much less hassle and get quicker results.

    ScriptForge abundant methods are organized in reusable modules that cleanly isolate Basic/Python programming
    language constructs from ODF document content accesses and user interface(UI) features.

    The scriptforge.py module
        - implements a protocol between Python (user) scripts and the ScriptForge Basic library
        - contains the interfaces (classes and attributes) to be used in Python user scripts
          to run the services implemented in the standard libraries shipped with LibreOffice

    Usage:

        When Python and LibreOffice run in the same process (usual case): either
            from scriptforge import *   # or, better ...
            from scriptforge import CreateScriptService

        When Python and LibreOffice are started in separate processes,
        LibreOffice being started from console ... (example for Linux with port = 2021)
            ./soffice --accept='socket,host=localhost,port=2021;urp;'
        then use next statement:
            from scriptforge import *   # or, better ...
            from scriptforge import CreateScriptService, ScriptForge
            ScriptForge(hostname = 'localhost', port = 2021)

        Every service must subclass this class to be recognized as a valid service
        A service instance is created by the CreateScriptService method
        It can have a mirror in the Basic world or be totally defined in Python

        Every subclass must initialize 3 class properties:
            servicename (e.g. 'ScriptForge.FileSystem', 'ScriptForge.Basic')
            servicesynonyms (e.g. 'FileSystem', 'Basic')
            serviceimplementation: either 'python' or 'basic'
        This is sufficient to register the service in the Python world

        The communication with Basic is managed by 2 ScriptForge() methods:
            InvokeSimpleScript(): low level invocation of a Basic script. This script must be located
                in a usual Basic module. The result is passed as-is
            InvokeBasicService(): the result comes back encapsulated with additional info
                The result is interpreted in the method
                The invoked script can be a property or a method of a Basic class or usual module
        It is up to every service method to determine which method to use

        For Basic services only:
            Each instance is identified by its
                - object reference: the real Basic object embedded as a UNO wrapper object
                - object type ('SF_String', 'DICTIONARY', ...)
                - class module: 1 for usual modules, 2 for class modules
                - name (form, control, ... name) - may be blank

            The role of the SFServices() superclass is mainly to propose a generic properties management
            Properties are got and set following next strategy:
                1. Property names are controlled strictly ('Value' or 'value', not 'VALUE')
                2. Getting a property value for the first time is always done via a Basic call
                3. Next occurrences are fetched from the Python dictionary of the instance if the property
                   is read-only, otherwise via a Basic call
                4. Read-only properties may be modified or deleted exceptionally by the class
                   when self.internal == True. The latter must immediately be reset after use

            Each subclass must define its interface with the user scripts:
            1.  The properties
                Property names are proper-cased
                Conventionally, camel-cased and lower-cased synonyms are supported where relevant
                    a dictionary named 'serviceproperties' with keys = (proper-cased) property names and value = boolean
                        True = editable, False = read-only
                    a list named 'localProperties' reserved to properties for internal use
                        e.g. oDlg.Controls() is a method that uses '_Controls' to hold the list of available controls
                When
                    forceGetProperty = False    # Standard behaviour
                read-only serviceproperties are buffered in Python after their 1st get request to Basic
                Otherwise set it to True to force a recomputation at each property getter invocation
                If there is a need to handle a specific property in a specific manner:
                    @property
                    def myProperty(self):
                        return self.GetProperty('myProperty')
            2   The methods

                    def myMethod(self, arg1, arg2 = ''):
                        return self.Execute(self.vbMethod, 'myMethod', arg1, arg2)
                Method names are proper-cased, arguments are lower-cased
                Conventionally, camel-cased and lower-cased homonyms are supported where relevant
                All arguments must be present and initialized before the call to Basic, if any
