Re: Any affordable Python-based CRM & ERP solutions?
Will wrote: Hi all, Please excuse the longish post. I'm new to Python (and programming), but love what I see and believe it to be an important language. I have (at least) one retail client (with single outlet at present) that requires a total business solution for their operation, preferably open source. They need: - an ecommerce website providing sales, customer service, order tracking and an opt-in newsletter - system for tracking inventory - full accounting system, tied-into the ecommerce website-- so full front-end and back-end system integration - possibly even point of sale tied-into the above. They've been using Windows up until now, but are happy to consider Linux, BSD, Mac, etc, as long as there's not a huge learning curve (they merely want a solution that works and is cost-effective). Other than standard accounting reporting requirements, they need the ability to add tax to local transactions. I have Googled with not a lot of contenders (Compiere-- http://www.compiere.org/index.html -- not Python and an Oracle license is required to run it; and I've just started reading about Bizar Shop-- http://www.bizarshop.com.au/). Anything else I've seen is either really expensive, doesn't fit the bill, or are not Python-based (which I'd ultimately like to promote). Because of the above requirements I was thinking something quite modular (that could be added to in future) would be the way to go. I like what I have seen with Plone and Zope but am unsure at present (given limited experience with these products) how one would integrate something into those solutions (if package didn't come from one 'vendor'), so that at least on the surface, everything appeared pretty seamless. Is this wishful thinking in Python at present? If so, have you encountered any other open source solutions that cover part of the above with Python handling the rest (and being easily integrated)? I look forward to any feedback. Thanks very much in advance. Cheers, Will :) Maybe http://www.erp5.org/ is what you are looking for! -- http://mail.python.org/mailman/listinfo/python-list

tkFont.Font(...) is a class instance, while you need font description.

What to use for installation?
Hello! I wrote a crossplatform Glade/GTK+ application for learning foreign languages (it is called Snakememory but doesn't have site in English yet). Currently it works from the directory where it was unpacked. But I need installation script that will compile and install translations, install application on Unix or create installation bundle for Windows. I have a three choices: distutils, make and scons. I think that distutils can't handle many tasks and make will require installing the whole cygwin for packaging on Windows, so the only remaining choice is scons. But I want to know other opinions before going with scons. What is the best tool for installing python applications? Eugene -- http://mail.python.org/mailman/listinfo/python-list
Development infrastructure - need python packaging gurus help, please
Hi! I'm trying to create a development infrastructure that would allow for simple and unified ways of sharing, *deploying* and *reusing* the code within private entity. I can see that pip with virtual environments and requirements.txt is very similar to dependency management provided by maven or apache ivy. But there seems to be a disconnect between the egg carrying the possibility to be importable and executable, but in the same time considered to be deprecated format which is not fully supported by pip and virtualenv and wheel not having those basic questions answered... Here is what i'm trying to achieve: 1. I want to be able to specify the set of dependencies for the project i'm currently developing and make them available for the import. Think java jar - having it in class path allows for the code reuse (import packages provided) as well as for the execution. 2. I want to be able to put the newly created project in a form of artifact in a some central location from which it can be taken to be imported or executed or included into "class path". Again think java jar. If i have it in some location i can use ivy or maven to manage the dependencies and provide it to me upon request 3. I want to be able to deploy the program and execute it. So the problem with all this as i see it: The importable and executable format is egg, but it is deprecated! Sane dependency management is pip and virtualenv, but they don't support eggs fully (pip install --egg is having the disclaimer that it s not working ok sometimes) wheel is pretty much unusable for anything other then installing into the virtualenv. Am i missing something? Thanks in advance, Eugene -- https://mail.python.org/mailman/listinfo/python-list

Re: Tough Scrolling question with Tkinter
Hi Saqib,
AFAIU, you want to change the scrollregion, not the size. So try:
def _b1PressEvt(event):
x0,y0,x1,y1 = canvas.config('scrollregion')[4]
print x0,y0,x1,y1
canvas.config(scrollregion=(int(x0),int(y0),int(x1)+100,int(y1)))
First click will show nothing, because first change keeps the scrollregion
entirely in the window.

Setting an exclusive lock on a file
Hi all,
I want to set an exclusive lock on a file so other processes wouldn't
be able to write to it.
So I write
import fcntl
fd=open('myfile','w')
fcntl.lockf(fd, fcntl.LOCK_EX)
fd.write('some bytes')
fd.close()
But it turns out that my script doesn't write anything to file whereas
other processes do. What's wrong in my code?

cross platform ping module
Hi all! I'm interested in developing a cross platform module that will allow a simple 'ping' functionality, i mean sending icmp type 8 code 0 and receiving appropriate answers. This sound like a simple work, but i ask for your help with architectural decision. I can implement icmp communications using raw sockets (possibly, as an extension coded in C), or i can use subproccess module, ask system ping executable to do the work, and just parse it's output. There are problems with both solutions. First one will require root (or equivalent) privileges for the interpreter to work. This is unavoidable, we can just make the program suid, but sometimes (as to my mind, always) it is not an option. Security matters, i can't allow each and every untested application to run with root privileges. Besides, this will require the user to actually have root access to make program suid. I'm unsure about the way something similar to suid can be done on windows, too. Second one just plain looks ugly to me. I don't like the approach at all. But, this would avoid all security troubles with suid, because if the user can run ping, we can too. And this also mean sysadmin actually allowed the user to run ping. On the other hand, this will limit us to icmp types that concrete system's ping executable can work with. This means that on some systems we can use only type 8/ type 0 (i would like to use few others too). If i just needed a tool for specific environment, i would have easily chosen. But i'm going to create a module that everyone and everywhere could use. >From this point of view, calling system ping looks better. Can you please help me choose the correct way to handle this problem? Maybe, there are some other possibilities, witch i haven't taken into account? Is someone here interested in this functionality, anyway? Sorry for my poor English. -- http://mail.python.org/mailman/listinfo/python-list

calling command line programs?
Hi all, This is probably a very newbie question, but after searching google and docs @ python.org I can't find an answer, so maybe someone would be able to help? I'd like to call command-line functions from my python script (like you would in perl using backticks)... Is there a way of doing this? And if so, how does the environment get treated (I have some variables in my env that the programs I'd be calling need to see). Thanks much!

poplib.retr doens't flag message as read
Hi there,
I am trying to use the poplib library to get emails using the retr
method. The small program bellow works but the message aren't flagged as
read which puzzles me. I believe the pop server is qmail 1.0.6 /
vpopmail 5.2.1 and I am running the following script on Windows using
Pyhton 2.5.
import poplib
import email
pop = poplib.POP3('mail.server.com')
pop.user('[EMAIL PROTECTED]')
pop.pass_('password')
status, msg_list, octets = pop.list()
for msg_number in [msg.split(' ')[0] for msg in msg_list]:
status, lines, octets = pop.retr(msg_number)
msg = email.message_from_string('\n'.join(lines))
if not msg.is_multipart() and msg.get_content_type() == 'text/plain':
print msg.get('Subject')
print msg.get_payload()
pop.quit()
Why aren't the message flagged as read? Is there a way to manually mark
them read?

EuroPython vs PyconUK
I do realize that the UK is not really part of Europe (no polemic :P) but I am nevertheless curious about the logic behind creating another major Python event in Europe. Wasn't EuroPython enough? Like many I am sure, I probably won't be able to attend both (and I really enjoyed the Geneva experience so definitely want to renew "it"). How would you go about selecting which conference to attend? They are only 2 months apart, 6 would have been easier for the attendees! Could the organizers liaise one way or another to make Pythoneers life as easy and fun as the language and give as much information out as possible as early as possible (early bird early) for people to make the best decision? I know marketing matters but ... EuGeNe -- http://www.3kwa.com -- http://mail.python.org/mailman/listinfo/python-list

If Guido was a rock star and I was a groupie, I would want to know which festival to attend to see him on stage. I guess there is always Google Video ;) More seriously in Geneva there were people from all over the place, speakers and attendees, which is one of the reason why such conferences are interesting (or am I deluded?). It is harder for someone from Australia to come twice to Europe in the space of 2 months than for a pythoneer lambda to spend a couple of days studying another web framework to see if it fits how his brain works and the problem he's got to solve. Looking at the reactions to my post, I must be wrong. I didn't mean to offend anyone if I did. I'll go to Vilnius because I have never seen the city and try to go to Birmingham if the program looks interesting (not very rational or is it?).

I agree it is great to see the Python scene grow (everywhere). The AFPY is organizing "journees python francophones" early June too cf. http://journees.afpy.org/.

Busy as you'd expect from someone working for Google, decides to make the trip to Europe for a Python related conference, henceforth spends 3 1/2 months in Europe so he can do Italy in June (he is listed as an organizer), Lithuania in July and UK in September...

base64 and unicode
Hi,
I am trying to convert the file hebrew.b64 attached into hebrew.lang
(text file usable by Inline Search <http://www.ieforge.com/InlineSearch>
for localization purposes.
>>> import base64
>>> base64.decode(file("hebrew.b64","r"),file("hebrew.lang","w"))
It runs but the result is not correct: some of the lines in hebrew.lang
are correct but not all of them (hebrew.expected.lang is the correct
file). I guess it is a unicode problem but can't seem to find out how to
fix it.
hebrew.b64 = file to convert

Thanks for the "wb" tip that works (see bellow). I guess it is

file / module / package - import problem
Hi there,
I have a "problem" which could be a bad design on my behalf but I am not
sure so ...
I have a package WMI which contains a module hauteur.py which, when
imported, load data from a file located in WMI/data/. In hauteur.py I
call open('data/hauteur.yaml').
test.py
WMI/
hauteur.py
data/
hauteur.yaml
lot.py
It works well when hauteur is imported in lot.py but if I try import
WMI.hauteur in test.py it doesn't work because it looks for the
hauteur.yaml file in the "wrong" place.
Is there a way to tell a module in a package to look for a file in a
specific place i.e. a within package location?
