Python_Session : Session class

Contents

# 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.

## Piemēri:

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"])

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

## LibreOffice Basic Session class:

            Option Explicit
            Option Compatible
            Option ClassModule

            Private _ps As Object ' Private member

            Private Sub Class_Initialize()
                GlobalScope.BasicLibraries.LoadLibrary("Tools")
                Set _ps = CreateUnoService("com.sun.star.util.PathSubstitution")
            End Sub ' Constructor

            Private Sub Class_Terminate()
                _ps = Nothing
            End Sub ' Destructor

            Public Property Get SharedScripts() As String
                Dim inst As String, shr As String
                inst = ConvertFromURL(_ps.getSubstituteVariableValue("$(prog)"))
                shr = Tools.Strings.ReplaceString(inst,"Share","program")
                SharedScripts = shr & GetPathSeparator() &"Scripts"
            End Property ' Session.sharedScripts

            Public Property Get SharedPythonScripts() As String
                sharedPythonScripts = sharedScripts() & GetPathSeparator() &"python"
            End Property ' Session.sharedPythonScripts

            Public Property Get UserName() As String ' User account name
                userName = _ps.getSubstituteVariableValue("$(username)")
            End Property ' Session.userName

            Public Property Get UserProfile() As String ' User profile system path
                userProfile = ConvertFromURL(_ps.getSubstituteVariableValue("$(user)"))
            End Property ' Session.userProfile

            Public Property Get UserScripts() As String ' User scripts system path
                userScripts = userProfile() & GetPathSeparator() &"Scripts"
            End Property ' Session.userScripts

            Public Property Get UserPythonScripts() As String ' User Python scripts system path
                userPythonScripts = userScripts() & GetPathSeparator() &"python"
            End Property ' Session.userPythonScripts
