Re: Parsing text

Hi,
I'm trying to write a fairly basic text parser to split up scenes and
acts in plays to put them into XML. I've managed to get the text split
into the blocks of scenes and acts and returned correctly but I'm
trying to refine this and get the relevant scene number when the split
is made but I keep getting an NoneType error trying to read the block
inside the for loop and nothing is being returned. I'd be grateful for
some suggestions as to how to get this working.
for scene in text.split('Scene'):
num = re.compile(^\s\[0-9, i{1,4}, v], re.I)
textNum = num.match(scene)
if textNum:
print textNum
else:
print No scene number
m = 'div type=scene'
m += scene
m += '\div'
print m
Thanks, Iain

Are you trying to match Roman numerals? As others have said, it is difficult to
make any suggestions without knowing the input to your program.
You may want to look at PyParsing (http://pyparsing.wikispaces.com/) to parse
the text file without messing with regular expressions.

[issue5897] No library reference tree in chm help file

Re: Web framework for embedded system
Thomas Heller theller at python.net writes: I'm looking for a lightweight web-framework for an embedded system. The system is running a realtime linux-variant on a 200 MHz ARM processor, Python reports a performance of around 500 pystones. You can start with webpy (http://webpy.org/) and build up from there. The web application will not be too fancy, no databases involved for example, but it will need to control some simple peripherals (some parallel in/out, some dacs) attached to the system. It should provide a user interface showing the current state and allowing to manipulate it via a browser, and I will probably need to support some rpc as well. Does this sound sensible at all? Any suggestions? I don't know how Python will affect the real-time tasks your system is performing. You may want to look at a web framework in C (e.g. http://www.koanlogic.com/klone/index.html).

Tested on Vista Home Premium 64bit with Python 2.6.2 all tests pass except: 16-model_dialog.py - If the model dialog Spanish Inqisition is closed by pressing ENTER key, it pops up again. However, clicking buttons works fine. Minor nitpicks: 1. Menu accelerators are not enabled by default i.e. pressing Alt + F does not open the File menu. 2. Alt + F4 does not close the window. 3. None of the controls (except menus) have _Vista look_ to them (http://dl.getdropbox.com/u/14797/no_vista_theme.png). Still no idea what's causing the object has been destroyed error on Windows XP, though. Does this happen for everyone? Is there anyone who *has* got 12-scroll.py working for them on XP? I have never seen this error either on XP or Vista. 12-scroll.py has always worked for me. Regards, Suraj -- http://mail.python.org/mailman/listinfo/python-list

Re: Modifying the value of a float-like object
Eric.Le.Bigot at spectro.jussieu.fr writes: Hello, Is there a way to easily build an object that behaves exactly like a float, but whose value can be changed? The goal is to maintain a list [x, y,…] of these float-like objects, and to modify their value on the fly (with something like x.value = 3.14) so that any expression like x +y uses the new value. Have you looked at sympy (http://code.google.com/p/sympy/)? It implements symbolic mathematics so you can define the equations put in the values to get the result. You should be able to derive from the Symbol class to implement the accuracy behavior. Regards, Suraj -- http://mail.python.org/mailman/listinfo/python-list

Greg Ewing greg.ewing at canterbury.ac.nz writes: PyGUI 2.0.1 is available: Thank you very much for this GUI toolkit. I always wanted something like this on windows. I installed this and tried out the tests on Python 2.6.1 and Windows XP SP3. Following are my observations. I will try to send some patches once I have looked at the code in detail. After installing on windows I had to manually delete C:\python26\lib\site-packages\GUI\Win32\__init__.py in order to get it work. Test 02-window.py: 1. Resizing window produces white horizontal bars. Use double buffering to prevent this? Test 05-checkbox.py: 1. Checkbok background is a black rectangle. Test 06-radiobutton.py: 1. Radiobutton has a white background. Test 09-textfield.py: 1. All textfields have black area at right bottom. 2. For multiline textfield, the black are is not painted over during repaint. 3. Textfields no not have XP style borders. Test 15-dialog.py: 1. Alt+F4 does not work. However Ctrl+Q works fine. 2. Initially keyboard navigation is not possible. Once a button is clicked, it is focused and keyboard navigation is possible. 2. If Cancel button has focus, pressing Enter should print Cancel. Currently it prints OK. 3. Pressing spacebar should activate focused button. Test 18-exceptions.py: 1. Printing traceback to console is not sufficient on windows. Test 29-slider.py: 1. Defenitions of 'live' and 'non-live' are swapped in the printed message. Test 33-mouse-events.py: 1. mouse-enter and mouse-leave events are not reported. Test 37-image-cursor.py: 1. Mouse pointer hotspot is in the middle of the image. Test 38-keys.py: 1. Key combinations with Ctrl Alt are not detected properly. 2. Scroll-lock is reported as f14 3. Pause/Break is reported as f15 4. Caps-lock Num-lock are detected as keycodes but 'key' is not reported.

[issue5355] Expat parser error constants are string descriptions
New submission from Suraj Barkale suraj+pyt...@barkale.com:
All the error constants in `xml.parsers.expat.errors` are strings.
However, when expat raises an ExpatError exception, ExpatError.code
attribute is a number. There seems to be no way of associating
ExpatError with a corresponding error code from `xml.parsers.expat.errors.
Following code snippet should print Ignore empty file but in Python
2.6 it raises ExpatError.
from xml.etree import ElementTree
from xml.parsers import expat
try:
ElementTree.parse('')
except expat.ExpatError as e:
if e.code == expat.errors.XML_ERROR_NO_ELEMENTS:
print Ignore empty file
else:
raise

Re: dbus-python for windows
est electronixtar at gmail.com writes: I am trying to port Scribes to Windows, Hi there like minded fellow sourceforge.net/projects/windbus/≥ but it not for Python, so how could I install dbus module for Windows Python 2.5 ? I have also started to dabble in windbus-python for the sake of Scribes. I have following observations: 1. I don't have Visual Studio 2003 (required for compiling Python 2.x modules) so alternative is to use MinGW. Follow instructions at http://js.cx/~justin/mingw You can skip the GtkGLExt part. 2. Checkout windbus from sourceforge, apply the patch (patch.exe doesn't work on Vista. Rename it to p4tch.exe) 3. Follow the windows build instructions for windbus. It gets compiled correctly :). 4. dbus-python has dependency on dbus AND dbus-glib. But all my attempts of getting dbus-glib to build have failed so for. 5. dbus-python looks at wrong place for python headers, this is very easy to connect and if we can get dbus-glib to build then we are there :) I will keep banging my head let you know once I have cracked it (or the dbus-python :) P.S.
