Guida di LibreOfficeDev 24.8
La console interattiva Python, conosciuta anche come interprete Python o shell Python, offre ai programmatori un modo rapido per eseguire comandi e provare e analizzare il codice senza dover creare un file. L'introspezione degli oggetti UNO, così come la documentazione dei moduli Python di LibreOfficeDev, si può ottenere da terminale.
Da una copia di LibreOfficeDev inclusa in una distribuzione GNU/Linux, usate il terminale come illustrato:
I comandi del terminale whereis o type contribuiscono a localizzare la console interattiva di Python:
user@computer:~$ type -p python3
/usr/bin/python3
user@computer:~$ /usr/bin/python3
Python 3.7.5 (default, Nov 20 2019, 09:21:52)

From a full-featured LibreOfficeDev installed package, a Basic or Python script locates the embedded copy of Python console.
This routine resorts to Platform class module in order to distinguish the actual operating system.
Sub interpreter_console
Set opsys = New Platform
ps = CreateUnoService("com.sun.star.util.PathSettings")
install_path = ConvertFromURL(ps.Module)
If opsys.isMacOSX Then
cmd = "/System/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal "
pgm_path = Array( install_path,"..","Resources","python" )
ElseIf opsys.isLinux Then
cmd = "x-terminal-emulator -e "
pgm_path = Array(install_path,"python")
ElseIf opsys.isWindows Then
cmd = ""
pgm_path = Array("python")
EndIf
python_interpreter = Join( pgm_path, GetPathSeparator() )
Shell(cmd + python_interpreter)
End Sub
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
import uno, os, subprocess
def interpreter_console():
ctx = XSCRIPTCONTEXT.getComponentContext()
smgr = ctx.getServiceManager()
ps = smgr.createInstanceWithContext("com.sun.star.util.PathSettings", ctx)
install_path = uno.fileUrlToSystemPath(ps.Module)
pgm = install_path + os.sep + "python" # Python shell/console path
subprocess.Popen(pgm) # Start Python interactive Shell
Come alternativa usate la console dell'estensione APSO:
