Re: QWebView: notify python when I clicked on a certain web eleemnt
I have a web page (existing page, can't modify it) and I would like to browse it in a QtWebview. (This is already working) Now I Wonder how I could achieve following behaviour: When I click on a certain element e.g. span id=clickme/a I would like to notify my python script. What is important: I don't want to change anything else in the web pages behaviour (This means if clicking on this element will call some java script functions, load a pag, then this should still happen. You can inject JavaScript using the method QWebElement::evaluateJavaScript() Also you can insert a Python object in the JS runtime with QWebFrame::addToJavaScriptWindowObject() see here: http://pysnippet.blogspot.com/2010/01/calling-python-from-javascript-in- pyqts.html so make a Python object with some methods you'd wish to call, then evaluate some small JS that will bind the click event on your element to the method of the Python object. -- дамјан ((( http://damjan.softver.org.mk/ ))) Teaching a pig to sing wastes your time annoys the pig. -- http://mail.python.org/mailman/listinfo/python-list

Given the context, PyQt is available under the GPL and a commercial license, the commercial license Phil is talking about is not the GPL. Which is a wrong interpretation of “commercial”.

Re: AtrributeDict
I've needed an attribute accessible dict, so I created this.
Are there any obviously stupid shortcomings?
If you know the attribute names ahead of time, you might consider
using a namedtuple instead.
See
http://docs.python.org/library/collections.html#collections.namedtuple
I do use it, even when I don't know the attribute names, see how:
from collections import namedtuple
def build_namespace_tuple(nsmap):
nsmap is a dictionary of XML namespaces (from lxml)
namespaces = namedtuple('namespaces', ' '.join(nsmap.keys()))
return namespaces(*['{%s}' % x for x in nsmap.values()])
If I didn't need the dict values wrapped in {} I could've just used:
return namespaces(*nsmap.values())
and it's all fine, just completely immutable, which is not always
desirable.

Why? - Python is object oriented, but I can write whole systems without defining a single class.

Let take some http library as an example, the author would certainly think that hiding the socket object is the only sane thing to do.

Using lxml to screen scrap a site, problem with charset
So, I'm using lxml to screen scrap a site that uses the cyrillic
alphabet (windows-1251 encoding). The sites HTML doesn't have the META
..content-type.. charset=.. header, but does have a HTTP header that
specifies the charset... so they are standards compliant enough.
Now when I run this code:
from lxml import html
doc = html.parse('http://a1.com.mk/')
root = doc.getroot()
title = root.cssselect(('head title'))[0]
print title.text
the title.text is а unicode string, but it has been wrongly decoded as
latin1 - unicode
So.. is this a deficiency/bug in lxml or I'm doing something wrong.
Also, what are my other options here?
I'm running Python 2.6.1 and python-lxml 2.1.4 on Linux if matters.

Re: Tools for using virtual environments and PEP 370
Python 2.6 implemented PEP 370: Per-user site-packages Directory Ok, you can completelly replace virtualenv with a) setting PYTHONUSERBASE=something b) Editing ~/.pydistutils.cfg to be like: [install] user=True After this, installing new packages go to $PYTHONUSERBASE/lib/python2.6/site-packages/. I've also tried pip.py and it mostly works fine with this setup except for one bug where it tries to write a install-record-%s.txt file in /usr/lib/.../ I've hacked it with this crude patch (which is not correct always). @@ -1388,7 +1389,8 @@ if sys.platform == 'win32': install_location = os.path.join(sys.prefix, 'Lib') else: -install_location = os.path.join(sys.prefix, 'lib', 'python%s' % sys.version[:3]) +import site +install_location = os.path.join(site.USER_BASE, 'lib', 'python%s' % sys.version[:3]) record_filename = os.path.join(install_location, 'install-record-%s.txt' % self.name) ## FIXME: I'm not sure if this is a reasonable location; probably not -- дамјан ( http://softver.org.mk/damjan/ ) A: Because it reverses the logical flow of converstion.

Re: Tools for using virtual environments and PEP 370
Python 2.6 implemented PEP 370: Per-user site-packages Directory[1] Now, are there any tools I could use to create and activate virtual environments like workingenv, virtualenv etc. but that will use PYTHONUSERBASE instead of hard-linking the python program. [1] http://docs.python.org/dev/whatsnew/2.6.html#pep-370-per-user-site-packages-directory I tested again and setting PYTHONUSERBASE=dir where dir was created with virtualenv works just fine. Now, it would be interesting to see if all those hacks that virtualenv does are neccesseary or not. ps. Of course I did try this before writing the original post, but it seems I was bitten by a bug in my own code. -- дамјан ( http://softver.org.mk/damjan/ ) A: Because it messes up the order in which people normally read text.

Re: end child process when parent dies (on Unix)
I'm starting a Unix tool with subprocess.Popen() from a python script and I want the child to be killed when the parent (my script) ends for whatever reason *including* if it gets killed by SIGKILL. A Linux-specific solution is prctl(2). I've tried this in a test C program... exactly what I need. Now if I could slip this between the fork and exec in subprocess.Popen() -- дамјан ( http://softver.org.mk/damjan/ ) In theory, there is no difference between theory and practice.

end child process when parent dies (on Unix)
Hi all, I'm starting a Unix tool with subprocess.Popen() from a python script and I want the child to be killed when the parent (my script) ends for whatever reason *including* if it gets killed by SIGKILL. For normal situations I can send a signal to the pid of the Popen object. But not if the script ends abnormally (SIGKILL etc). AFAIK there were some tricks with process leaders and stuff like that so if someone remembers the exact semantics of that could refresh my memory. -- дамјан ( http://softver.org.mk/damjan/ ) A: Because it messes up the order in which people normally read text.

Re: Single-instance daemons
As per Stevens/Rago, file and record locking provides a convenient
mutual-exclusion mechanism.
On linux (at least) there's one nice trick to get a single-instance
program. Create a unix domain socket, and bind it to an address that
begins with the null character '\0'. You can bind the same address a
second time, and if the process dies the socket is automatically
destroyed. It will not leave anything on the filesystem.
def single_instance(id):
import socket
s = socket.socket(socket.AF_UNIX, socket.SOCK_DGRAM)
s.bind('\0' + id)
return s
