Getting Session Information

Computing LibreOffice user profile and shared modules system file paths can be performed with Python or with Basic languages. BeanShell, Java, JavaScript and Python scripts locations can be derived from this information.

Ar Python čaulu.

>>> from <the_module> import Session

>>> print(Session.SharedPythonScripts()) # static method

>>> print(Session().UserName) # object property

>>> input(Session().UserProfile) # object property

From Tools – Macros - Run Macro... menu.


        from <the_module> import Session
            
        def demo_session():
            import screen_io as ui
            ui.MsgBox(Session.Share(),title='Installation Share')  # static method
            ui.Print(Session.SharedPythonScripts())  # static method
            s = Session()  # instance creation
            ui.MsgBox(s.UserName,title='Hello')  # object property
            ui.Print(s.UserPythonScripts)  # object property
            
        g_exportedScripts = (demo_session,)  # public macros
    

Ar LibreOffice Basic.


        Sub Session_example()
            Dim s As New Session ' instance of Session class
            Print "Shared scripts location:", s.SharedScripts
            MsgBox s.UserName,,"Hello"
            Print s.UserScripts, Chr(13), s.UserPythonScripts
        End Sub ' Session_example
    

Using COM/OLE and Visual Basic Scripting language.


        ' The service manager is always the entry point
        ' If there is no office running then an office is started up
        Set sm = WScript.CreateObject("com.sun.star.ServiceManager")
        ' PathSubstitution service exhibits information to infer
        ' <UserProfile|Share>/Scripts/python locations from
        Set obj = sm.createInstance("com.sun.star.util.PathSubstitution")
            
        MsgBox CreateObject("WScript.Network").UserName,, "Hello"
        user = obj.getSubstituteVariableValue("$(user)")
        MsgBox user & "/Scripts",, "User scripts location"
        libO = Replace(obj.getSubstituteVariableValue("$(inst)"), "program/..", "Share")
        MsgBox libO & "/Scripts",, "Shared scripts location"
    

Python Session class:


        import getpass, os, os.path, uno
            
        class Session():
            @staticmethod
            def substitute(var_name):
                ctx = uno.getComponentContext()
                ps = ctx.getServiceManager().createInstanceWithContext(
                    'com.sun.star.util.PathSubstitution', ctx)
                return ps.getSubstituteVariableValue(var_name)
            @staticmethod
            def Share():
                inst = uno.fileUrlToSystemPath(Session.substitute("$(prog)"))
                return os.path.normpath(inst.replace('program', "Share"))
            @staticmethod
            def SharedScripts():
                return ''.join([Session.Share(), os.sep, "Scripts"])
            @staticmethod
            def SharedPythonScripts():
                return ''.join([Session.SharedScripts(), os.sep, 'python'])
            @property  # alternative to '$(username)' variable
            def UserName(self): return getpass.getuser()
            @property
            def UserProfile(self):
                return uno.fileUrlToSystemPath(Session.substitute("$(user)"))
            @property
            def UserScripts(self):
                return ''.join([self.UserProfile, os.sep, 'Scripts'])
            @property
            def UserPythonScripts(self):
                return ''.join([self.UserScripts, os.sep, "python"])
    
note

Unlike Basic, pathname normalization is performed with Python inside Session class.
