best macro to detect the operating system

edit

@librebel Thanks!

Thanks in kind, they call me a Necromancer now :))

Nice job! I had to change user to share to get this to work. And just out of curiosity, as it seems the arrays do nothing, what are they used for? They don't return anything.

Thanks @EasyTrieve :)

aParams:    all parameters
aOutParamIndex: the indices of all parameters that are specified as out or inout.
aOutParam:  the values of all parameters that are specified as out or inout.

Example: aOutParamIndex == { 1, 4 } means that aOutParam[0] contains the out value of the aParams[4] parameter. (see XInvocation)

@librebel, Thanks again. This still doesn't make any sense to me, but don't worry, I'll figure it out at some point.

!!! ?????? BTW, has anyone actually confirmed what this returns from OSX?

... The reason I ask this is because after playing around with this a little, and especially when getting .nodename, .release, .version, and .hardware from os.uname(), I noticed that for me os.uname().hardware is not working, BUT ... if I return os.uname() as an array, I then get the hardware info. And also I get Linux (capitalized, instead of lower case). This is strange. Seems flaky. Just say'n.

In this particular case the arrays do nothing, since get_OS() has no parameters.. If the value of a passed argument is changed by a function, the updated value can be retrieved afterwards from the aOutParam() array.

Figured out the user / share thing. There are two places to put python code. Run this to list them:

Function getPythonPaths()
    Dim oPathSettings As Object : oPathSettings = createUnoService("com.sun.star.util.PathSettings")
    Dim s       As String
    Dim sMsgBox As String
    For Each s In Split(oPathSettings.Basic,";")
        sMsgBox = sMsgBox & left(s,len(s)-len("/basic")) & "/Scripts/python" & chr(10)
    Next
    msgbox sMsgBox
End Function

Win users please adjust slash.

@EasyTrieve See 'Python script' section here .

Nice job @EasyTrieve... one note about the "g_exportedScripts", it expects a string list which defines the python functions within your .py-file that are made executable from within LibreOffice. If there is no more than 1 function name in the string list, it should for some reason end with a comma, e.g.:

g_exportedScripts = macro1,

for 2 or more exported functions:

g_exportedScripts = macro1, macro2

@librebel, Thanks. Humm? It works for me without the comma. Figured w/ python's zest for brevity, it was worth a try. Can't find official documentation on g_exportedScripts. But from DuckDuckGo g_exportedScripts I can see that others use it w/ a comma. Only thing I can figure is it might need a comma in older or newer versions. my: python --version gives "2.7.9". What's your version?

The comma at the end of one item makes it a tuple. See documentation.

@Ratslinger now it make sense .. however when i put a single method name inside tuple brackets () it still requires the extra comma. Perhaps it must be a 2-tuple at the least, where the second element may be empty... @EasyTrieve my Python version is 3.5.2 .. but i also have 2.7 installed from before :)

@Ratslinger, thanks, that's interesting. @librebel, the 'documentation' Ratslinger mentions says this: "Note that it is actually the comma which makes a tuple, not the parentheses." ...And looks like I've got some more updating to do.

OSTYPE and MACHTYPE on Mint 18 show as MACHTYPE=x86_64-pc-linux-gnu, OSTYPE=linux-gnu.

use set | less to list.

Ubuntu 16.04:

MACHTYPE=x86_64-pc-linux-gnu

OSTYPE=linux-gnu

Anybody help with the OSX results?

@Pansmanser Did you try the basic/Python solution presented by @librebel ( original suggestion by @karolus )? On my Mint system it returns Linux. Don't have others to test, but have no reason to believe it won't work.

Thanks, @Ratslinger - I'm trying the @librebel/@karolus solution, as shown above. Meanwhile, environ("MACHTYPE") and environ("OSTYPE") return null strings on my sys and are not present when I list environment variables.

@Pansmanser Running set | less using terminal will only display the first page initially. At the : prompt did you press enter or down arrow for more entries? It can be a long list which is the reason to display 'less'.

@Ratslinger Thanks for that. Yes, set | less (how do you do that highlighting?) throws up MACHTYPE and OSTYPE. However they are still not detected by environ(). Any fix for that?

Let's stick with Python script. Script name should be get_os.py. Contents should be (with comma at end):

#!/usr/bin/env python3
def get_OS( ):
   import sys
   return sys.platform
g_exportedScripts = get_OS,

placed in this directory: /home/robert/.config/libreoffice/4/user/Scripts/python

Basic sub code:

Sub PrintMyOS
    Dim oScriptProvider, oScript
    Dim aParams(), aOutParamIndex(), aOutParam()
    oScriptProvider = ThisComponent.getScriptProvider()
    oScript = oScriptProvider.getScript( "vnd.sun.star.script:get_os.py$get_OS?language=Python&location=user" )
    get_sys_platform = oScript.invoke( aParams(), aOutParamIndex(), aOutParam() )
    Print get_sys_platform
End Sub

Run the sub & you should get result.

No, unfortunately not the result I want. Both routines present and correct (paste & copied from your code, as previously from librebel). Throwing up same exception error at same line.
