# Identifying the operating system

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

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

## Using a Python class:

            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).

            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

## 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
