As you see my get methods aren't much more than redirections to the object's own methods - one could access them directly via MyHandler.pages[12] or MyHandler.pages,getSortedArray() Best regards, Henning Hraban Ramm Südkurier Medienhaus / MediaPro Support/Admin/Development Dept.

XML handler design
by Henning.Ramm＠mediapro-gmbh.de March 24, 2005

March 24, 2005

Hi there! I just wrote a SAX handler for XML files that describe a newspaper issue (list of pages etc.); I'd like to know if I could do it better. def startElement(self, name, attrs): """call an own handler method named _start_Something for a Something element if it exists, to avoid a long list of 'if name== ...'""" self._queue.append(name) # keep the order of processed tags handler = str('_start_'+name) if hasattr(self, handler): self.__class__.__dict__[handler](self, attrs) # is there a better syntax for this? The different element handlers fill an array of custom Page objects (self.pages). One gets this array either directly as MyHandler.pages or via def getPages(self): return self.pages.getSortedArray() # no, it's not a plain array ;-) def getPage(self, no): return self.pages[no] Is that the right way to get data from a handler? Like in: parser = xml.sax.make_parser() parser.setFeature(xml.sax.handler.feature_namespaces, 0) pxh = MyHandler() parser.setContentHandler(pxh) parser.parse(dateiname) for p in pxh.getPages(): ... I guess it would be better (more logical) to get the data from the parser? Further, if I'd like to use it in a twisted driven asynchronous app, would I let the parser run in a thread? (Or how can I make the parser non-blocking?) Best regards, Henning Hraban Ramm Südkurier Medienhaus / MediaPro Support/Admin/Development Dept.

I'm a Linux refugee familiar used to programming pygtk apps with glade and decided to see how to make Cocoa apps. I downloaded the pybobc 1.3b1 and py2app that Bob announced about a week ago. I'm following the tutorial and go to the step where I'm supposed to run: /usr/bin/python setup.py py2app -A and I get: Traceback (most recent call last): File "setup.py", line 2, in ? import py2app File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/ python2.3/site-packages/py2app/__init__.py", line 43, in ? import distutils.dist, distutils.core, distutils.command, build_app, sys File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/ python2.3/site-packages/py2app/build_app.py", line 24, in ? from py2app.find_modules import find_modules, parse_mf_results File "/Library/Python/2.3/py2app/py2app/__init__.py", line 33, in ? import py2app.install ImportError: No module named install Here is what I think is the relevant directory listing: 516 mac:/Library/Python/2.3/py2app/py2app $ ls -l total 464 -rw-rw-r-- 1 dreed admin 1185 30 Dec 21:18 __init__.py -rw-rw-r-- 1 dreed admin 1382 17 Mar 21:34 __init__.pyc -rw-rw-r-- 1 dreed admin 227 17 Mar 21:34 __init__.pyo drwxrwxr-x 14 dreed admin 476 23 Mar 16:32 apptemplate/ drwxrwxr-x 35 dreed admin 1190 23 Mar 16:32 bootstrap/ -rw-rw-r-- 1 dreed admin 37063 12 Mar 23:58 build_app.py -rw-rw-r-- 1 dreed admin 42985 17 Mar 21:34 build_app.pyc -rw-rw-r-- 1 dreed admin 42603 17 Mar 21:34 build_app.pyo drwxrwxr-x 14 dreed admin 476 23 Mar 16:32 bundletemplate/ drwxrwxr-x 5 dreed admin 170 23 Mar 16:32 command/ -rw-rw-r-- 1 dreed admin 1320 3 Dec 02:43 create_appbundle.py -rw-rw-r-- 1 dreed admin 1976 17 Mar 21:34 create_appbundle.pyc -rw-rw-r-- 1 dreed admin 1976 17 Mar 21:34 create_appbundle.pyo -rw-rw-r-- 1 dreed admin 1312 3 Dec 02:07 create_pluginbundle.py -rw-rw-r-- 1 dreed admin 2006 17 Mar 21:34 create_pluginbundle.pyc -rw-rw-r-- 1 dreed admin 2006 17 Mar 21:34 create_pluginbundle.pyo -rw-rw-r-- 1 dreed admin 993 9 Feb 18:24 filters.py -rw-rw-r-- 1 dreed admin 1809 17 Mar 21:34 filters.pyc -rw-rw-r-- 1 dreed admin 1537 17 Mar 21:34 filters.pyo -rw-rw-r-- 1 dreed admin 812 9 Dec 13:12 install.py -rw-rw-r-- 1 dreed admin 1402 17 Mar 21:34 install.pyc -rw-rw-r-- 1 dreed admin 1106 17 Mar 21:34 install.pyo drwxrwxr-x 27 dreed admin 918 23 Mar 16:32 recipes/ drwxrwxr-x 8 dreed admin 272 23 Mar 16:32 scripts/ -rw-rw-r-- 1 dreed admin 12264 12 Feb 02:56 util.py -rw-rw-r-- 1 dreed admin 16365 17 Mar 21:34 util.pyc -rw-rw-r-- 1 dreed admin 15028 17 Mar 21:34 util.pyo I see the install.py file.

ANN: New PyQt-Mac-03-2005 binary installer available
by Kevin Walzer March 23, 2005

March 23, 2005

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We have released a new binary installer of PyQt-Mac, PyQt-Mac-03-2005, which packages PyQt for Mac OS X. This installer updates all components of PyQt to the latest versions: PyQt 3.14.1, Sip 4.2.1, QScintilla 1.5.1, Qt 3.3.4, and Eric 3 (PyQt IDE) 3.6.2 This version differs from previous releases of PyQt-Mac by handling all installation details, no longer requiring the user to run additional installer scripts. The result is a significantly smaller installer package (60 MB) and final installation (250 MB). Based on user requests, we have also added instructions on how to build PyQt on Mac OS X to the "ReadMe" documentation; this material is also included on the web page for PyQt-Mac.

Yet, I'm still hesitant to send the entire list of errors. Anyway: Looking on the first few lines let me search for mysql_config. All I found was a binary in my PHP folder - but this has got nothing to do with MySQL for Python. There is no other mysql_config file on the system. setup.py tries to use 'popen' on 'mysql_config'. Well, from this point on I still have no idea how to proceed and want to raise the very same question: Any hints? Thanks, Christian

installing MySQL for Python
by Christian Meesters March 23, 2005

March 23, 2005

Hi Has anybody experience installing MySQL-Python (v1.2)? In this case I'd like to install it for the standard 2.3 (for the record: I'm using 10.3.8 with Python Panther Fix). Simply starting 'python setup.py build' results in a bunch of errors and compiler warning and eventually fails: #just the last few errors and warnings for brevity: _mysql.c: In function `_mysql_ResultObject_setattr': _mysql.c:2360: error: `v' undeclared (first use in this function) _mysql.c:2371: error: `name' undeclared (first use in this function) _mysql.c:2372: error: `self' undeclared (first use in this function) _mysql.c: At top level: _mysql.c:172: warning: `_mysql_server_init__doc__' defined but not used _mysql.c:183: warning: `_mysql_server_init' defined but not used _mysql.c:267: warning: `_mysql_server_end__doc__' defined but not used _mysql.c:273: warning: `_mysql_server_end' defined but not used error: command '/System/Library/Frameworks/Python.framework/Versions/2.3/lib/ python2.3/config/PantherPythonFix/run-gcc' failed with exit status 1 Any idea how I could solve my problem? It's not the first time problems with MySQL for Python are discussed on this list, but I can't see how much my problem is related to what we have had before. So, I hope you forgive me asking this if this question was raised in some other way before. Thanks a lot in advance. Cheers Christian

ANN: py2app 0.1.8
by Bob Ippolito March 23, 2005

March 23, 2005

(see also: <http://bob.pythonmac.org/archives/2005/03/17/ann-py2app-018/>) `py2app`_ is the bundlebuilder replacement we've all been waiting for. It is implemented as a distutils command, similar to `py2exe`_, that builds Mac OS X applications from Python scripts, extensions, and related data files. It tries very hard to include all dependencies it can find so that your application can be distributed standalone, as Mac OS X applications should be. `py2app`_ 0.1.8 will be included in the installer for `PyObjC`_ 1.3. If you have installed `PyObjC`_ 1.3, then you already have `py2app`_ 0.1.8 installed. Download and related links are here: http://undefined.org/python/#py2app py2app 0.1.8 is a major enhancements release: Bugs fixed: - Symlinks in included frameworks should be preserved correctly (fixes Tcl/Tk) - Fixes some minor issues with alias bundles - Removed implicit SpiderImagePlugin -> ImageTk reference in PIL recipe - The ``--optimize`` option should work now - ``weakref`` is now included by default - ``anydbm``'s dynamic dependencies are now in the standard implies list - Errors on app launch are brought to the front so the user does not miss them - bdist_mpkg now compatible with pychecker (data_files had issues) Options changed: - deprecated ``--strip``, it is now on by default - new ``--no-strip`` option to turn off stripping of executables New features: - Looks for a hacked version of the PyOpenGL __init__.py so that it doesn't have to include the whole package in order to get at the stupid version file. - New ``loader_files`` key that a recipe can return in order to ensure that non-code ends up in the .zip (the pygame recipe uses this) - Now scans all files in the bundle and normalizes Mach-O load commands, not just extensions. This helps out when using the ``--package`` option, when including frameworks that have plugins, etc. - An embedded Python interpreter is now included in the executable bundle (``sys.executable`` points to it), this currently only works for framework builds of Python - New ``macho_standalone`` tool - New ``macho_find`` tool - Major enhancements to the way plugins are built - bdist_mpkg now has a ``--zipdist`` option to build zip files from the built package - The bdist_mpkg "Installed to:" description is now based on the package install root, rather than the build root .. _`py2app`: http://undefined.org/python/#py2app .. _`pyobjc`: http://pyobjc.sourceforge.net/ .. _`py2exe`: http://starship.python.net/crew/theller/py2exe/
