py.edit.js -- a simple python editor in javascript
I thought people here might be interested in a simple, lightweight Python editor written in Javascript. Something to use when blogging or replying to comments. Its just a proof-of-concept -- something I've had rolling in my head for a while. http://py-edit-js.appspot.com/ Features: - simplistic auto indent/dedent of lines - can output as html, text - bookmarklet mode - opens a mini-editor within the current page - spaces at the beginning of a line, dedents the next line by that many blocks -- an easy way to close blocks. Bugs: - sometimes the Javascript Bookmarklet doesn't close, when the user tries to close it I've tested it with Safari Firefox under OS X. -sri -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
Ironclad v0.7 released (compiled CPython extensions on IronPython)
Hi all I'm delighted to announce the release of Ironclad v0.7, which is now available from http://code.google.com/p/ironclad/downloads/list . This release is a major step forward: * Runs transparently on vanilla IronPython 2.0RC2, without creating extra PythonEngines or breaking .NET namespace imports * Many numpy 1.2 tests (from the core, fft, lib, linalg and random subpackages) now reliably pass (run ipy numpytests.py from the build directory) * Significant performance improvements (by several orders of magnitude in some places :D) So... if you want to use numpy (or other C extension modules) with IronPython on Win32, please download it and try it out; I'm very keen to hear your experiences, and to know which neglected features will be most useful to you.

Terry Reedy: The problem is that inner functions do not exist until the outer function is called and the inner def is executed.

Or maybe because you want to denote a logical nesting, or maybe because you want to keep the outer namespace cleaner, etc etc. --- Benjamin: Of course, you could resort to terrible evil like this: My point was of course to ask about possible changes to CPython, so you don't need evil hacks anymore. --- Steven D'Aprano: For this to change wouldn't be a little change, it would be a large change.

Re: what's so difficult about namespace?
From: Kaz Kylheku [EMAIL PROTECTED] Scheme hasn't officially supported breaking a program into multiple files until R6RS. If the language is defined in terms of one translation unit, it doesn't make sense to have a namespace feature. Good point. Note that any language that uses optionally-loadable libraries automatically has more than one translation unit, namely the application itself and at least one loaded library. More on this later. Javascript programs are scanned at the character level by the browser as part of loading a page. So there are severe practical limitations on how large Javascript programs can be. That's only half the reason. The other half is that JavaScript doesn't support requiring additional libraries to be downloaded from another site to be added to the main JavaScript application, right? Namespaces are useful only in very large programs. Or in medium sized programs that require loading libraries written by other people, of the total set of all such libraries is too large to globally manage well enough to avoid name clashes. The main program might not use namespaces internally, but the various libraries *must* use namespaces internally, and then the main program must arrange for external functions to be propertly called with namespace+localname. The essence of a true namespace or package system or whatever is that you can establish situations in which you use the unqualified names. Correct. You can emulate namespaces by adding prefixes to identifiers, which is how people get by in C. With the pain that you must always use the fully-qualified name, right? In C, you can even get the functionality of short names using the preprocessor. I hear Greenspun there! :-) I have done this before (but only once). ... (Story of a Greenspun task. Yes, I agree what you did, after the fact, to avoid needing to manually edit all the files in your source to have fully-qualified names when porting for others to use, was a reasonable hack.)

Is this a bug?
No, because you've actually imported two different modules (even
though it's the same file on disk, for the second inport statement
Python imports the file again because it was done from a different
absolute path, that is, the module data is always different from the
module test.data even if they refer to the same file).
However, I'm not so sure the effect of os.chdir() on the import path
is a good idea. It would seem that among people who use os.chdir() in
their programs, some will want the import path to change with it, some
will not. You can't please everyone, so I would suggest that we
should choose in favor of limiting context sensitivity. I like to
think that import abc always does the same thing regardless of any
seemingly unrelated state changes of my program, especially since, as
the OP pointed out, import is used as a means to ensure singleness.
Thus, if I were designing the language, I would have sys.path[0] be
the current working directory at program start.
To the OP: My first suggestion is to consider not using os.chdir() in
your programs, and instead construct pathnames with the directory
included. If you do use os.chdir(), then early in your script script,
add a line such as sys.path[0] = os.getcwd(). Then, no matter where
you are, always import the file relative to the starting directory.
So always use from test.data import DATA, even after you os.chdir().

def __add(self,j):

if __name__ == __main__:
o=MyObject()
o.js.kiki(12).kuku()()
===
If i run the script : it will display :
Add:kiki('12').kuku()
Because the JQueryCaller caller is called, by the () trick at the
end of the last line
I'd like to display the same thing, but without the need to put the
() at then end !

on my JQueryCaller)

If there's N possible code paths, can you think about all of them at the same time while you look at your code and simultaneously understand them all? If I write: if foo: do_this() else: do_that() it's easy to get a good mental picture of all the consequences of foo being true or false. As the number of paths go up, it becomes harder to think of them all as a coherent piece of code and you have to resort to examining the paths sequentially. -- http://mail.python.org/mailman/listinfo/python-list

This could be a source of puzzling bugs. There are many ways of dealing with this.

by doing that, you create an action ... when you will call print it
will call the __str__ (__repr__ is better in that case), which will
call the callback of myobject.
In my preceding post, the action was called by the () trick at the

This is resolved in the Python 2.x series by implementing PEP 328 URL:http://www.python.org/dev/peps/pep-0328/, such that the search path for ‘import’ does *not* contain the current directory, and requiring relative-to-the-current-directory imports to be explicitly requested. PEP 328 doesn't say anything about that. Using Python 2.5, which PEP 328 claims implements this change, I see the same behavior that Victor Kerkez sees. My sys.path[0] is still the empty string, meaning that Python does start its import search from the current directory. Perhaps you are confusing current directory with directory that the current module file is in, which PEP 328 does address? (It's ok, the PEP itself used current directory in this way.)

I just want to make a jquery wrapper, and let people use it to write
jquery call on the server side in a python way ...
o is a object, imagine a widget : like a textarea or input box
js is a special attribut of o, which will let you write javascript
for this object.
o=MyObject()
o.js.toggleClass(clean).hide()
When I will render the object to a http/html output : it will generate
something like (a javascript call): $(#idOfMyObject).toggleClass
(clean).hide();
It's all what I want in the real world.
I wouldn't do something like that (with the () tricks at the end on

The fourth, the first and thrid result are wrong beacuse they are level

The fifth it Ok
The sixth shows only one result and it should show two.

Unicode regex and Hindi language
The regex below identifies words in all languages I tested, but not in
Hindi:
# -*- coding: utf-8 -*-
import re
pat = re.compile('^(\w+)$', re.U)
langs = ('English', '中文', 'हिन्दी')
for l in langs:
m = pat.search(l.decode('utf-8'))
print l, m and m.group(1)
Output:
English English
中文 中文
हिन्दी None
From this is assumed that the Hindi text contains punctuation or other
characters that prevent the word match. Now, even more alienating is
this:
pat = re.compile('^(\W+)$', re.U) # note: now \W
for l in langs:
m = pat.search(l.decode('utf-8'))
print l, m and m.group(1)
Output:
English None
中文 None
हिन्दी None
How can the Hindi be both not a word and not not a word??
Any clue would be much appreciated!
Best.

Explicit is better that implicit: don't have the one method do both appending to the object *and* calling the object. The basic idea isn't so bad. The OP tries to create a syntactic look-alike to the way the javascript library jQuery works, which does these chained calls, with the purpose of making the writing of JS serverside (something you sometimes for dynamic JS) within the same DSL. If this is nicely integrated, it actually could be neat. OTOH, I go with -strings string interpolation - works good enough for me... Diez -- http://mail.python.org/mailman/listinfo/python-list

I'm not actually using os.chidir(), I just used it here to create a clearer example. Here is the simplest representation of the problem: http://www.ninjashare.com/904415 $ cd singleton_test $ export PYTHONPATH=. $ python application/main_script.py Creating class Singleton Creating class MySingleton Creating class Singleton Creating class MySingleton $ Ah ha. That's a slightly different issue. Here's the problem: when you type python application/main_script.py, Python doens't call the module it runs application,main_script like you'd expect. Instead it calls the module __main__. Thus, when you later import application.main_script, Python doesn't see any already-loaded modules called application.main_script, so it imports the file again (this time calling the module application.main_script). Try it this way: python -c 'import application.main_script' In this example, Python the string passed to -c is considered the __main__ module, so when you import application.main_script it calls the module it imports application.main_script, so you will get the behavior you expect. The thing you have to remember is, Never try to reimport the main script; it just won't work. If you find yourself doing that, create a tiny script whose sole job is to import the real main script (and maybe set up sys.path), and run that. (Also, some people consider reciprocal imports to be bad style. I'm not one of them per se but I find that it's worth the effort to avoid them if it's easy to do so.)

It's not a word, but that doesn't mean that it consists entirely of
non-alpha characters either. Here's what Python gets to see:

I think the problem is that the Hindi Text contains both alphanumeric

much less how it's held in unicode, but take a look at the output of
this code:

for lang in langs:
print lang
for char in lang:

E LATIN CAPITAL LETTER E (Lu)
n LATIN SMALL LETTER N (Ll)

द DEVANAGARI LETTER DA (Lo)

From that, we see that there are some characters in the Hindi string
that aren't letters (they're not in unicode category L), but are
instead marks (unicode category M).

I know that the Python roadmap answer to such questions might refer to Python 3.0 and its strings are Unicode features, and having seen this mentioned a lot recently, I'm surprised that no-one has done so at the time of writing, but I do wonder whether good old Python 2.x wouldn't benefit from a more explicit error message in these situations. Since the introduction of Unicode in Python 1.6/2.0, I've always tried to make the distinction between what I call plain strings or byte strings and Unicode objects or character strings, and perhaps the UnicodeEncodeError message should be enhanced to say what is actually going on: that an attempt is being made to convert characters into byte values and that the chosen way of doing so (which often involves the default, ASCII encoding) cannot manage the job.

Re: Confused about class relationships
John O'Hagan [EMAIL PROTECTED] wrote: Apologies if this is a D.Q., I'm still learning to use classes, and this little problem has proved too specific to find in the tutorials. I have two classes with a relationship that I find confusing. One is called Engine, and it has a method (bar_builder) which generates instances of the other class, called Bar (not as in Foo but as in bar of music; inherits from list). Also, Bar takes the generating instance of Engine as an argument to its __init__ method: class Bar(list): def __init__(self, a_bar, args, engine): list.__init__ (self, a_bar) self[:] = a_bar self.args = args self.engine = engine #more instance attributes... #methods... class Engine: def __init__(self, args): self.args = args #more instance attributes... def bar_builder(self): #body of method generates lists... yield Bar([generated_list], args, self) #more methods... #(other stuff...) def main(args): engine = Engine(args) bars = engine.bar_builder() for a_bar in bars: #play the music!... While this works (to my surprise!) and solves the problem which motivated it (i.e. Engine instances need to pass some attributes to Bar instances ), it seems too convoluted. Should one class inherit the other? If so, which way around? Or is it fine as is? You need to put on a philosophical hat for this. Inheritance is used for an is-a relationship, where one thing is-a special type of another thing. Is Engine a special type of Bar? Is Bar a generic type of Engine? I think the answer is no, and because of that inheritance is not the right answer. I'm hoping this is a common trap I've fallen into; I just haven't been able to get my head around it. (I'm a musician...) Why do you think this is a trap? Engine creates Bars. Bars need to know about the Engine. I think you have expressed that relationship properly. When I have these kinds of philosophical debates over my own code, I always try to summarize them in the comments inside the module, just so others can get inside my head to understand the thinking that led to my design. -- Tim Roberts, [EMAIL PROTECTED] Providenza Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list

In Python 2.5, the PEP is implemented to the point that the absolute import behaviour is available by adding a ‘from __future__ import absolute_import’. Without that, yes, you will see the same behaviour as reported by Victor. The schedule of implementing significant changes like this is standardised for Python (by PEP 5), and the timeline is explicitly documented in the relevant section of PEP 328: Timeline In Python 2.5, you must enable the new absolute import behavior with from __future__ import absolute_import You may use relative imports freely. In Python 2.6, any import statement that results in an intra-package import will raise DeprecationWarning (this also applies to from import that fails to use the relative import syntax).

(including computer languages). So it not only matches words, it also
matches non-words like '123' and '0x000' and '0123_' and 10 viramas --
in other words, you may need to filter out false positives. Also, in
some languages (e.g. Chinese) a word consists of one or more

identify whole clauses or sentences.

This is down to the definition of word character. Should \w match Mc

character with any combining characters, ie just Lo or Lo, Lo+Mc,
Lo+Mc+Mc, etc?

Ok, I've taken this wise suggestion on board and of course I found immediately ways to improve the method. -However- this generates another issue. I can fragment the code of the original method into one public method and a few private support methods. But this doesn't reduce the complexity of the testing because the number and complexity of the possible path stays more or less the same. The solution to this would be to test the individual methods separately, but is the only way to test private methods in python to make them (temporarily) non private? I guess ultimately this would only require the removal of the appropriate double-underscores followed by method testing and then adding the double-underscores back in place. There is no cleaner way, is there? Manu Your experiences are one of the reasons that writing the tests *first* can be so helpful. You think about the *behaviour* you want from your units and you test for that behaviour - *then* you write the code until the tests pass. This means that your code is testable, but which usually means simpler and better. By the way, to reduce the number of independent code paths you need to test you can use mocking. You only need to test the logic inside the methods you create (testing behaviour), and not every possible combination of paths.

I don't see -any- of the responses in this thread voting for
anything other than a more civil approach to your request.
I am still flabbergasted by the solid resistance to promoting Python.
I think the posters have mostly promoted Python rationally, and not
promoted Python irrationally. Python is a good language, and Ruby is
not a bad one. From what posters say, it's possible I'll end up using
Ruby or Scheme in the future, especially if they're the better choice
for the task, though not exclusively.
It is sad that devotion is such a two-sided coin. If you devote your
time, memory, and attention to a principle or idea, you exclude
others. Rational devotion, though, unless a contradiction in terms,
is merely allocation.
Here of all places, NOT even one person(well Terry did kinda half
agree with me =), wants to support Python. I am completely perplexed.
I'm actually honored that the posters here reply to me sometimes. I'm
just in my 20s so I shouldn't expect them to really. But one thing
that comes with realism (as opposed to zealotry), is a solid
examination of one's leader's advice, the alternatives, and other
leaders' advice. And realism is good.
You OWE your
allegence to Python and the BDFL.
I don't see how this follows from any of your premises. Can you start
with concrete observations and draw the conclusion you want? I could
see that taking this as a premise, you could conclude that one is
devoted to Python and the BDFL. Your argument is:
M: X reads c-l-python.
C: X owes his allegiance to Python and the BDFL.
You haven't made any observations much stronger than the major
premise, M, and unless you're making stronger assumptions that it, you
can't deduce C. In the general case, I take the meaning of 'owe' to
participate in something like:
M: X has paid Z to Y, not free.
C: Y owes Z to X.
Python and Guido have not paid me allegiance. So I don't owe them
allegiance. If you intended to make an argument for follower-ship
('fellowship'?) and devotion, something like:
M: Python is good.
C: Yay for Python.
Then you haven't even proven your major premise.
Taking debt (what one owes) to also originate from a collective, i.e.
the community, we also have:
Lemma: The community has granted Z to Y, such that Z is good. ('The
shirt on your back', 'your life', e.g.)
Major: One can pay a community by paying a particular leader or emblem
with relation T to the community.
Minor: Y owes Z to the community.
Conclusion: Y can pay by paying the leader.
To conclude that '[the audience owes its] allegiance to Guido and
Python', assuming that 'a community paid Z to Y' and 'Y paid Z to the
community' are well-defined, you're missing:
1: Allegiance is good.
2: The community has given the audience good things.
3: Guido and Python have relation T to the community.
They are yet to be shown. My assumption has been that you're using
'owe' in the sense of honor, not vendetta, which I leave.

Some days ago I thought it would be interesting to add a class offering the possibility to run the asyncore loop into a thread so that a user can run the server without blocking the entire application. It could be useful, for example, in case someone wants to integrate a GUI. Since I'm not good with multi-threaded programming I'd like some opinions about the code I'm going to paste below. The FTPServer class that I inherited in my subclass is the dispatcher which listens on port 21 dispatching the incoming connection to an handler. The polling loop (FTPServer.serve_forever()) is wrapped in the run method. As you can see I acquire and release the lock (threading.Lock) every time I call the polling loop. My question is: is that really necessary? Should I expect some weird behavior by running the main loop into a thread like I did? Thanks in advance I found it hard to read through it.

python.org coming back as unreachable in Dillo (IPv6 routing error?)
Though only semi-Python related, it impacts me because I (until recently) use Dillo at home for browsing docs.python.org. I'm trying to figure out if something network-related changed. Within the last week or two (time-frame is fuzzy), it seems that something changed and I now get Network unreachable errors. AFAIK, I haven't changed any settings on my local Debian box. The best of my google-fu has returned that this may have something to do with ipv6 routing. Firefox, Epiphany and Lynx all work fine (as does Safari on my Mac on the same internal home network). Likewise, browsing with Dillo to IPv4 address-space seems to work fine. Have any network changes taken place at python.org (particularly IPv6 or DNS related) recently?
