Hey Rob,
I actually started with that event, until I came across the modified
event. I'm working on syntax highlighting. So I need any text change.
Also, colorizing on a key release is annoyingly noticeable to the
user. I tried it :)
I'm sure there are going to be other perils along the way as this is
my first attempt at syntax highlighing. I can load a file and the
highlighting works very well. I used an elaborate regex with named
groups and re.finditer(). I either use the names directly as edit
tags, or they help me look up other tags in a dict. It's quite fast.

That part wasn't bad at all. Now I need to code the text change
logistics but this bindtags ordering has got me perplexed.

Re: Parsing Problems

Hi,
I have just started learning python.I need to parse an XML file
and present the contents in a particular format.The format is called
as ini file.I have written some code.A section of the format needs
the data to be present in format as given below:
[Services]
supported=0x10,0x1A,0x3B,0x20,0x27,0x28,0x34,0x36,0x3E,0xA2,0xA5,0x2D,
0x22,0xA9,0x04,0xAA,0xAE
My code for this section parses the xml file and gives :
[Services]
Supported=['0x3e', '0x28', '0x3b', '0x22', '0x20', '0x27', '0xaa',
'0x10', '0xae', '0x34', '0x36', '0x2d', '0xa9', '0xa5', '0x4', '0xa2',
'0x1a']
{forget the numericals matching}.As you can see there
are single quotes around numericals ,which is not desired .I think the
problem lies in me using a list for storing and later printing out
values.I have attached few lines of code,not sure how clear it can be
to you:
for l in range(0,len(ser_par),
1):
if
ser_par[l].getAttribute('Semantics')==u'serviceId':
if
tag_exists(ser_par[l].childNodes,'VALUE'):
val =
ser_par[l].getElementsByTagName('VALUE')
value =
str(val[0].getAttribute('value'))
valu = hex(int(value))
rval.append(valu)
ser_par_num = ser_par_num + 1
prim_num = prim_num + 1
service_num = service_num + 1
variant_num = variant_num + 1
ser = list(set(rval))
print \n[Services]
print Supported=+str(ser)
How can i get rid of those single quotes.
Thanking you
shakeel
l = ['0x3e', '0x28', '0x3b', '0x22', '0x20', '0x27', '0xaa']
','.join(l)
'0x3e,0x28,0x3b,0x22,0x20,0x27,0xaa'
You may want to look at the ConfigParser package too. It's for reading/
writing .ini file.

Tkinter Modified and bindtags ordering
I'm trying to extract the text of the current line on the Modified
event.
It doesnt work if I delete a character. If I type 'abc' I get 'abc' in
text_changed().
If I hit backspace I still get 'abc'. Backspace once more, I get 'ab'.
So the
callback is called before the text is changed. But only on a delete.
Someone told me it has to do with bindtags ordering. I've read what
docs I can
find on the subject, but I cant figure out why it's not working. Maybe
I should
learn a bit of Tcl, eh?
import Tkinter as tk
def text_changed(evt):
global changing
if changing: return
changing = True
line, col = t.index('insert').split('.')
txt = t.get('%s.0' % line, '%s.end' % line)
print '|%s|' % txt
t.tk.call(t._w, 'edit', 'modified', 0)
changing = False
changing = False
root = tk.Tk()
t = tk.Text(master=root)
t.pack()
t.focus_set()
t.tk.call(t._w, 'edit', 'modified', 0)
t.bind('Modified', text_changed)

win32com short path name on 2k

Re: win32com short path name on 2k
I have no idea how Featurecam registers the type library. I did figure out that I can get the full name 'C:\Program Files\Featurecam' from within Featurecam using VBA and the same property I used in Pyhton - fc.InstallPath. Why would VBA and Python return two different strings? This is really driving me nuts, because I know for a fact I was getting the long name using python on 2k not 3 days ago, but now it's returning the short name and I haven't changed/installed anything. -- bytecolor -- http://mail.python.org/mailman/listinfo/python-list

instance references?
I'm working on a simple graphics package. I've got a function show() that the user needs to call at the end of the script to actually display the points, lines and circles that have been defined in the script. p1 = point(0, 0) l1 = line(1, 3, -4, 5) c1 = circle(-2, 3, 1) show() In each __init__() method of the point, line, and circle objects I add self to a list in a separate module, then show() uses this list to actually draw the objects. This works except: l1 = line(point(1, 3), point(-4, 5)) c1 = circle(point(-2, 3), 1) adds the references to the points used to define the objects to the render list. I only want objects that have been assigned to a variable to be rendered. (Try to ignore the function overloading.) So how can I tell if an instance of point, line or circle has actually been assigned to a variable? -- bytecolor -- http://mail.python.org/mailman/listinfo/python-list
Re: instance references?
Thanks Alex, the weak references *seem* to be doing what I want for now. In each __init__() I use: aptbase.drawables.append(weakref.ref(self)) Then in show(): for d in aptbase.drawables: o = d() if o is not None: # render it -- bytecolor -- http://mail.python.org/mailman/listinfo/python-list

Re: module to parse pseudo natural language?
Andrew E wrote: Hi all I've written a python program that adds orders into our order routing simulation system. It works well, and has a syntax along these lines: ./neworder --instrument NOKIA --size 23 --price MARKET --repeats 20 etc However, I'd like to add a mode that will handle, say: ./neworder buy 23 NOKIA at MKT x 20 I could enter several orders either by running multiple times, or use a comma-separated approach, like: ./neworder buy 23 NOKIA at MKT on helsinki, sell 20 NOKIA at market on helsinki You could add a string option instead: $ neworder -c 'buy 23 NOKIA at MKT on helsinki, sell 20 NOKIA at market on helsinki' This would leave your current option parsing in tact. Then just split on the comma. Another suggestion would be to drop into an interactive mode if no arguments are passed: $ neworder -? buy 23 NOKIA at MKT on helsinki -? sell 20 NOKIA at market on helsinki -? ^d The thing about this is that its a tolerant parser, so all of these should also work: # omit words like at, on ./neworder buy 23 NOKIA mkt helsinki # take any symbol for helsinki ./neworder buy 23 mkt helsinki # figure out that market=helsinki ./neworder buy 23 NOKIA at market price I've started writing a simple state-based parser, usage like: class NaturalLanguageInsructionBuilder: def parse( self, arglist ): Given a sequence of args, return an Instruction object ... return Instruction( instrument, size, price, ... ) class Instruction: encapsulate a single instruction to buy, sell, etc def __init__( self, instrument, size, price, ... ): ... This doesn't work yet, but I know with time I'll get there. Question is - is there a module out there that will already handle this approach? Thanks for any suggestions :) Andrew If I were in your situation, I'd probably write a BNF for the tiny-language. This would help wrap my brain around the problem. The BNF would help show what kind of regular expression you are looking at creating as well. -- bytecolor -- http://mail.python.org/mailman/listinfo/python-list
