# Identifying the operating system

Identifying the operating system can be performed with Python or Basic language.

## Using a Python class:

            """ the_module """
            import os, platform
            class Platform():
                @property
                def ComputerName(self): return platform.node()
                @property
                def DirSeparator(self): return os.sep
                @property
                def isLinux(self): return (self.OSName=='Linux')
                @property
                def isMacOSX(self): return (self.OSName=='Darwin')
                @property
                def isWindows(self): return (self.OSName=='Windows')
                @property
                def OSName(self): return platform.system()
                @property
                def PathDelimiter(self): return os.pathsep

## Using a Basic classmodule:

LibreOffice Basic lacks MacOS X native recognition. Platform identification is possible using LibreOffice Application Programming Interface (API).

            ''' Module name: Platform '''
            Option Compatible
            Option ClassModule
            Option Explicit

            Public Property Get ComputerName As String
                If isWindows Then ComputerName = Environ("ComputerName")
            End Property ' Platform.ComputerName

            Public Property Get DirSeparator As String
                DirSeparator = GetPathSeparator()
            End Property ' Platform.DirSeparator

            Public Property Get IsLinux As Boolean
                isLinux = ( GetGUIType()=4 ) ' Applies to macOS as well
            End Property ' Platform.isLinux

            Public Property Get IsMacOSX As Boolean
                isMacOSX = ( OSName="MAC" )
            End Property ' Platform.isMacOSX

            Public Property Get IsWindows As Boolean
                isWindows = ( GetGUIType()=1 )
            End Property ' Platform.isWindows

            Public Property Get OSName As String
                ' Return platform name as "MAC", "UNIX", "WIN"
                ' Inferred from "Tools.UCB.ShowHelperDialog" function
                With GlobalScope.Basiclibraries
                    If Not .IsLibraryLoaded("Tools") Then .LoadLibrary("Tools")
                End With
                Dim keyNode As Object ' com.sun.star.configuration.ConfigurationAccess
                keyNode = Tools.Misc.GetRegistryKeyContent("org.openoffice.Office.Common/Help")
                OSName = keyNode.GetByName("System")
            End Property ' Platform.OSName

            Public Property Get PathDelimiter As String
                Select Case OSName
                    Case "MAC", "UNIX" : PathDelimiter = ":"
                    Case "WIN" : PathDelimiter = ";"
                 End Select
            End Property ' Platform.PathDelimiter

ComputerName environment variable is solely available for Windows. Basic calls to Python macros help overcome LibreOffice Basic limitations.

## Examples:

With Python

>>> from < the_module > import Platform

>>> print(Platform().isMacOSX) # object property

True

>>> input(Platform().OSName) # object property

Darwin

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

            from < the_module > import Platform
            import screen_io as ui
            p = Platform()
            ui.MsgBox(''.join(['isMacOS: ',str(p.isMacOSX)]),0,p.OSName)

With LibreOffice Basic

            Sub Platform_example()
                Dim p As New Platform ' instance of Platform class
                MsgBox p.isLinux ' object property
                Print p.isWindows, p.OSName ' object properties
            End Sub ' Platform_example
