 Posted: Tue Mar 20, 2012 8:38 am Post subject: [Solved][PyUno] Getting the file path of the extension |
 |
|
When a python extension is added to libreoffice, the files for that extension are located in a arbitrarily named folder in /home/<user_name>/.libreoffice/3/user/uno_packages/cache/uno_packages . Is there anyway the script(extension) to find out the file path where the extension is installed...?
As an example if the extension is in a folder named lucio2yk.tmp_, the script should be able to find out that the full file path for it self is /home/<user_name>/.libreoffice/3/user/uno_packages/cache/uno_packages/lucio2yk.tmp_/6.zip/6.
Any help is highly appreciated

|
|
Hi Hanya, thank you again for the great help you are always extending towards me .
As you already know, I'm a newbie to Libreoffice. I wrote the following code.
self.ctx is setup by the code above in the class.
| Code: | pir = self.ctx.getValueByName(
"/singletons/com.sun.star.deployment.PackageInformationProvider" )
expath=pir.getExtensionList()
|
Till that point everything seems to be working. But the execution doesnt happen of the next line
| Code: | | text.insertString( cursor, type(expath), 0 ) |
or
| Code: | for exts in expath:
text.insertString( cursor, exts, 0 )
text.insertString( cursor, "\n", 0 ) |
But the interface XPackageInformationProvider ( http://api.libreoffice.org/docs/common/ref/com/sun/star/deployment/XPackageInformationProvider.html#getExtensionList ) clearly specifies that XPackageInformationProvider has a method named getExtensionList() which returns list.
What could be the reason for this weird problem..?  |

Why don't you use getPackageLocation method? getExtensionList method returns tuple of tuple in Python.
It seems you are working on Linux or UNIX environment, you can see standard output on such system. Start your office in terminal and then you can use print function of Python. |

I used that method because that method doesn't need any parameters. getPackageLocation method needs the id of the extension,which I don't know how to find at the moment .
Even when I use the getExtensionList method, noting is returned
Could it be because I'm not instantiating the singleton class properly...?

Hi,
| Code: | def vsp(*args):
ctx = XSCRIPTCONTEXT.getComponentContext()
pir = ctx.getValueByName(
"/singletons/com.sun.star.deployment.PackageInformationProvider" )
expath=pir.getExtensionList()
print(expath) |
This code shows me the following: | Code: | ((u'mytools.bookmarks.BookmarksMenu', u'1.0.0'),
(u'mytools.BookmarksMenu', u'0.6.2'), (u'mytools.bookmarks.BookmarksMenu.30ed1f7', u'1.0.0'),
(u'mytools.search.IncrementalSearch', u'0.1.0'),
(u'mytools.mri', u'1.1.0'),
(u'mytools.test.Mri', u'1.0.0')) |
The extension identifier used by getPackageLocation method is defined by identifier element in description.xml file of OXT package. See: http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/Extensions/Example |

Hanya,
I'm interestded in what you you are saying about the print function. I've opened office
by means of open -a LbreOffice.app and runned a macro placed in My Macros and with a print ("something") in it. However nothing is printed on the Terminal!
More to set up? I'm using OS X 10.7.3 |

|
|
Hi Hanya,
Thanks for your code. However, I haven' t got a working PC.
My old one with XP hangs up when I try to start it. I tried to fix it but have given it up.
But could you please describe how you do it in Linux o Unix with a simple
office macro with a python print command (statement ??) in it.
I would very much apprecciate that. |

Hi SuneOskar,
sys.stdout of Python is the reference to the output stream, maybe it writes something to a file or show it on a console. It can be replaced with an instance which has write method takes one argument as string to output.
On UNIX like environment, I can see the output to the console from Python when I start the office in the terminal. But Windows like environment does not provide such output.
This kind of toy helps me to see output directly on such silly environment. Read end of the code for how to use it.
| Code: |
import sys
import unohelper
from com.sun.star.util import XCloseListener
class WriterAsOutput(unohelper.Base, XCloseListener):
""" Toy of alternative output window.
If you change default font of standard paragraph style to
mono type and change mode to print layout, you can get
much better look.
"""
Out = None
def __init__(self):
self.doc = None
self._stdout = None
self._stderr = None
def disposing(self, ev): pass
def queryClosing(self, ev, ownership): pass
def notifyClosing(self, ev):
self.end()
def create_doc(self, ctx):
desktop = ctx.getServiceManager().createInstanceWithContext(
"com.sun.star.frame.Desktop", ctx)
return desktop.loadComponentFromURL(
"private:factory/swriter", "_blank", 0, ())
def start(self, ctx):
if self.__class__.Out is None:
self.doc = self.create_doc(ctx)
self.doc.addCloseListener(self)
self.__class__.Out = self
self._stdout = sys.stdout
self._stderr = sys.stderr
sys.stdout = self
sys.stderr = self
def end():
klass = WriterAsOutput
if not klass.Out is None:
i = klass.Out
i.doc = None
sys.stdout = i._stdout
sys.stderr = i._stderr
klass.Out = None
else:
sys.stdout = sys.__stdout__
sys.stderr = sys.__stderr__
end = staticmethod(end)
def _write(self, s):
if self.doc:
self.doc.getText().getEnd().setString(s)
def write(self, s):
self._write(s)
def start_output(*args):
""" Open writer document as output window. """
WriterAsOutput().start(XSCRIPTCONTEXT.getComponentContext())
def close_output(*args):
""" End to use the document as output window. """
WriterAsOutput.end()

It works for Mac OS X too if you start office from python in the Terminal.
For start i used:
| Code: | import subprocess
subprocess.call( [ '/applications/LibreOffice.app/Contents/MacOS/soffice.bin', '-scalc' ]) |
I didn't know how to start it from python but have been taught now.
Thanks Hanya for your interest and kindness. |
