如何从 python 脚本调用现有的 LibreOffice python 宏答案

【问题标题】：How to call an existing LibreOffice python macro from a python script如何从 python 脚本调用现有的 LibreOffice python 宏
【发布时间】：2015-04-02 15:46:40
【问题描述】：

目前我用这个来调用现有的 LibreOffice 宏：

def OnLOtimestamp(self):
        try:
            pid= Popen(['lowriter '"'"'vnd.sun.star.script:fs2TimeStamp.py$fs2_TimeStamp?language=Python&location=user'"'"],shell=True).pid
        except OSError, e:
            self.notify_show("Timestamp Error",str(e))
        self.ma2.SetLabel("Macro timestamp")
        self.database['Time_stamp'] = self.database['Time_stamp'] + 1

关键位是 Popen 调用，其中宏名称是 fs2TimeStamp.py，函数是 fs2_TimeStamp，但这感觉像是在逃避，我宁愿通过 Uno 直接调用。我的研究表明，我可能需要使用 MasterScriptProvider、XscriptProvider 和 XscriptInvocation，但尝试破译 Uno API 就像在糖浆中游泳。有人有使用 Uno 在 Libreoffice 中调用现有宏的代码示例吗？

编辑：
到目前为止，答案似乎是否定的！这是当前的游戏状态。

#!/usr/bin/python3
# -*- coding: utf-8 -*-
##
# a python script to run a libreoffice python macro externally
#
import uno
from com.sun.star.connection import NoConnectException
from com.sun.star.uno  import RuntimeException
from com.sun.star.uno  import Exception
from com.sun.star.lang import IllegalArgumentException
def test2(*args):
    localContext = uno.getComponentContext()
    localsmgr = localContext.ServiceManager
    resolver = localsmgr.createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver", localContext )
    try:
        ctx = resolver.resolve("uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext")
    except NoConnectException as e:
        print ("LibreOffice is not running or not listening on the port given - ("+e.Message+")")
        return
    except IllegalArgumentException as e:
        print ("Invalid argument given - ( "+ e.Message+ ")")
        return
    except RuntimeException as e:
        print ("An unknown error occurred: " + e.Message)
        return

    servmgr = ctx.ServiceManager
    desktop = servmgr.createInstanceWithContext( "com.sun.star.frame.Desktop",ctx)
    model = desktop.getCurrentComponent()
#    scriptP = model.getScriptProvider()
#    print("scriptP", scriptP)
    scriptx = model.getScriptProvider().getScript('vnd.sun.star.script:fs2TimeStamp.py$fs2_TimeStamp?language=Python&location=user')
    print("scriptx", scriptx)
    try:
        scriptx.invoke("",0,0)
    except IllegalArgumentException as e:
        print ("The command given is invalid ( "+ e.Message+ ")")
        return
    except RuntimeException as e:
        print("An unknown error occurred: " + e.Message)
        return
    except Exception as e:
        print ("Script error ( "+ e.Message+ ")")
        print(e)
        return
    except:
        print("Error")
    return(None)

test2()

当在 Libreoffice 中作为宏调用时，此代码运行良好，并且 scriptx 打印为：

scriptx <pythonscript.PythonScript object at 0x7fa2879c42e8>

但是，当从命令行运行时，脚本什么也不做，并且 scriptx 打印为：

scriptx pyuno object (com.sun.star.script.provider.XScript)0x1e749d8{, supportedInterfaces={com.sun.star.lang.XTypeProvider,com.sun.star.script.provider.XScript}}

所以 getScriptProvider 或 getScript 都没有提供他们需要的东西。我目前不知道缺少什么，但我从骨子里觉得我已经接近解决方案了。

谁能看到我哪里出错了？

最后，我有一个可行的解决方案。叮！董！

#!/usr/bin/python3

import uno
from com.sun.star.connection import NoConnectException
from com.sun.star.uno  import RuntimeException

from com.sun.star.lang import IllegalArgumentException
def test2(*args):
    localContext = uno.getComponentContext()
    localsmgr = localContext.ServiceManager
    resolver =  localsmgr.createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver", localContext )
    try:
        ctx = resolver.resolve("uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext")
    except NoConnectException as e:
        print ("LibreOffice is not running or not listening on the port given - ("+e.Message+")")
        return
    msp = ctx.getValueByName("/singletons/com.sun.star.script.provider.theMasterScriptProviderFactory")
    sp = msp.createScriptProvider("")
    scriptx = sp.getScript('vnd.sun.star.script:fs2TimeStamp.py$fs2_TimeStamp?language=Python&location=user')
    try:
        scriptx.invoke((), (), ())
    except IllegalArgumentException as e:
        print ("The command given is invalid ( "+ e.Message+ ")")
        return
    except RuntimeException as e:
        print("An unknown error occurred: " + e.Message)
        return
    except Exception as e:
        print ("Script error ( "+ e.Message+ ")")

return(None)

test2()

注意：为清楚起见，现有的 python 脚本称为fs2TimeStamp.py，它包含定义为def fs2_TimeStamp(*args):的1（一）个函数
见行：

scriptx = sp.getScript('vnd.sun.star.script:fs2TimeStamp.py$fs2_TimeStamp?language=Python&location=user')

它存储在$HOME/.config/libreoffice/4/user/Scripts/python

要使此解决方案发挥作用，libreoffice 必须在监听模式下运行，因此请使用以下命令启动 libreoffice：

soffice "--accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;" --writer --norestore

或

nohup soffice "--accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;" --writer --norestore &

您也可以使用更直接的方法（在本例中为 writer）：

lowriter "--accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp"

或

nohup lowriter "--accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp" &

另请注意，您必须使用 python3

运行脚本

这是第一个答案的更简单和更通用的版本，它非常倾向于我的具体问题，它称为宏，然后通过 TCP 与另一个程序通信，然后插入通过 TCP 连接发送的文本。
此版本将独立运行，并且应该可以立即复制。
和以前一样，您必须在侦听模式下启动 LibreOffice 编写器（有关选项，请参阅上一个答案）：

lowriter "--accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp"

这是外部python例程，必须用python3运行：

#!/usr/bin/python3
# -*- coding: utf-8 -*-
##
# a python script to run a libreoffice python macro externally
# NOTE: for this to run start libreoffice in the following manner
# soffice "--accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;" --writer --norestore
# OR
# nohup soffice "--accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;" --writer --norestore &

uno_directmacro()

这是 LibreOffice python 宏 directmacro.py 应该位于：

$HOME/.config/libreoffice/4/user/Scripts/python

（假设这里使用 LibreOffice 版本 4）

directmacro.py 宏：

#!/usr/bin/python
class FontSlant():
    from com.sun.star.awt.FontSlant import (NONE, ITALIC,)

def directmacro(*args):
#get the doc from the scripting context which is made available to all scripts
    desktop = XSCRIPTCONTEXT.getDesktop()
    model = desktop.getCurrentComponent()
    text = model.Text
    tRange = text.End
    cursor = desktop.getCurrentComponent().getCurrentController().getViewCursor()
    doc = XSCRIPTCONTEXT.getDocument()
    parentwindow = doc.CurrentController.Frame.ContainerWindow

# your cannot insert simple text and text into a table with the same method
# so we have to know if we are in a table or not.
# oTable and oCurCell will be null if we are not in a table
    oTable = cursor.TextTable
    oCurCell = cursor.Cell
    insert_text = "This is text inserted into a LibreOffice Document\ndirectly from a macro called externally"
    Text_Italic = FontSlant.ITALIC
    Text_None = FontSlant.NONE
    cursor.CharPosture=Text_Italic
    if oCurCell == None: # Are we inserting into a table or not?
        text.insertString(cursor, insert_text, 0)
    else:
        cell = oTable.getCellByName(oCurCell.CellName)
        cell.insertString(cursor, insert_text, False)
    cursor.CharPosture=Text_None
    return None
