Web interface GUI??

[Luc]

I am a newbye. I am looking for a multi-platform user interface solution
(windows, linux).
Untill now, I used wxPython which worked fine at the beginning (MDK9,
Windows NT4). Nevertheless, I was very disapointed when I noticed that my
applications did not work with recent linux distributions (MDK10.1, FC3).
This was because of the wxPython version...and it seemed to be very
difficult to come back to an older wxPython version with these new
distributions, because of dependencies problems.
So I am looking for another solution with a web interface that should work
with linux and windows XP.
I had a look to zope but was afraid with the complexity and debug
difficulties.
Are there some other solutions?

Sorry I was not clear enough. When I said "add", I meant concatenate
because I want to read 0x0588 as one value and ord() does not allow
that.

However you pointed me in the right direction and I found that int
(binascii.hexlify(a + b, 16)) does the job.

Thanks.

Reading hex to int from a binary string

[Luc]

Hi all,

I read data from a binary stream, so I get hex values as characters
(in a string) with escaped x, like "\x05\x88", instead of 0x05.

I am looking for a clean way to add these two values and turn them
into an integer, knowing that calling int() with base 16 throws an
invalid literal exception.

Any help appreciated, thanks.

Yes that too. But I have four bytes fields and single bit fields to
deal with as well so I'll stick with struct.

Crossplatform GUIs are a myth, you *always* end up with a lowest common
denominator (aka Windows) which makes your application look like crap on
other platforms. And when the toolkit/framework only makes it look like
semi-crap, it makes it *feel* like crap.

Because, you know, user interfaces aren't only about the look but also
(and most importantly) the feel, and the lowest common denominator (aka
Windows) won't bring a Mac feel to your app.

Crossplatform toolkits/frameworks suck. All of them. No exception. If
you want your app to look *AND* feel great on all platform, abstract the
core of your application and embed it in platform native GUI code.

Oh, I'm sure you do. Now go try to run one of your Dabo apps on a Mac
and see how it looks/feels... :>

Here's a hint directly taken from the Dabo homepage: "It also suffers
from the same display limitations on some platforms (most notably OS X),
but these should improve as the underlying toolkits improve."

No, sizers are a tiny part of a much bigger problem. Sizers might be the
key to solve parts of the "look" problem, they don't address any of the
"feel" problem.

But you clearly have a point here, so let me rephrase: "Crossplatform
toolkits/frameworks suck. All of them. No exception. UNLESS you only
target the lowest common denominator, aka Windows and its Linux
followers".

Now, the OP *explicitely* said that "[his] requirement is that the
application needs to look as good on Windows as on the Apple Mac", so
the rephrasing does not apply in this case. So here's a last try:

"Crossplatform toolkits/frameworks suck. All of them. No exception.
ESPECIALLY if one of your target is Mac OS".

I'm sorry, but the screenshots I'm seeing on the Dabo website all look
like ugly Windows ports (when they don't look like straight X11 crap). I
can't comment on the feel of course, but I wouldn't hold my breath. I'm
downloading the screencasts as we "speak", but I'm not holding my breath
either.

[UPDATE] I have watched three of the Dabo screencasts and the presented
application are *very* far from looking/feeling like native OS X
applications. Sorry.

Eh, funny, I have used wx thingy for quite some time (when it was
actually still called wxWindows and then when they switched to
wxWidgets) and it's probably the worst of all crossplatform toolkits I
have ever used. So I'm not sure you'll be able to convince me here :D

Ok, now here's a question for you: if crossplatform toolkits/frameworks
are so great and automagically allow to produce superlickable and
native-looking/feeling applications on all three major platforms, why is
there so few of those applications on OS X ? 

"Because Mac users are elitists assholes" is not the good answer by the
way :)

Yeah, I have watched three of them and they are glaring examples of what
I'm talking about. The applications presented not only don't look right,
at all, they apparently don't feel right either.

No it's not, because you insist on presenting only one part of the

No problem, let me get my chisel, do you prefer Fedex or UPS ? :p

marked-up Python code

[Luc Goossens]

Hi,

I would like to experiment with marked-up Python source code. A more  
elaborate explanation of the use-case is at the end of this mail. The  
short story is that I would like to do things like assign colors to  
pieces of text in my editor and have this information saved _in my  
source  code_
smth like

else :
  print "ERROR"
  return -1


"all" the Python parser has to do is skip the mark-up.

Has something like this been done before? Is there a way  to do this  
without changing the Python executable? If not, where in the source  
code should I start looking?

cheers,
Luc

PS1
I know I can put the mark-up after a # and the problem is solved  
trivially, but this will not work for all cases (e.g. mark-up of  
single identifiers) and to be honest I was thinking of recycling some  
mark-up capable editor and an existing mark-up language

PS2
here's the real use case
I have a small application in Python. The code shares a recurring  
feature: within methods 20% of the code lines is about the actual  
handling of the correct case, 40% is about the handling of the  
incorrect cases, 40% is instrumenting (logging and timing).
A case for aspect oriented programming? I would certainly think so,  
but unfortunately  there is no obvious way to map this to the  
prevailing aspect-advice-joint point-point cut model. Moreover, I  
really do not want this code to become fragmented over multiple  
source code files, I just want the aspects to be readily visible in  
my editor, and be able to selectively show/hide some of them (like  
expanding/collapsing code blocks).

Re: marked-up Python code

[Luc Goossens]

Hi Tim,

thanks for your suggestions

I have two questions.
1. can I color the background of the text keeping the normal syntax  
coloring for actual text? can you give some hints on how to do that  
in vim?
2. will the # mark-up lines show in the editor? is there some visual  
clue that something has been hidden?

I will gladly settle for some pointer into the vim documentation,  
which I found already.

many thanks,
Luc

Here is how I do such comparisons:

NO!  There ~is~ a conspiracy by Egg farmers to not make burgers available 
before 10 am.

Burger King used to be one of the last great vestiges of the 24 hour burger, 
and now it's gone.

They know no one would buy the shitty egg McMuffins/equivalent if they had 
delicious burgers available, so there is something underhanded going on 
behind the scenes.

Same thing with pizza.  Don't try to tell me that there are not hungry 
partiers at 3 am - but are any of the delivery places open?  NO!

Why is it this way?  Who knows!  But when in doubt, blame the right wing 
extremist politicians.

A person can live without hate, living love and working towards bettering 
humanity.

But as for people in general - I'm not so sure.  I'm not sure my opinion on 
hate - since I value people's opinions and diversity, hate seems unbecoming, 
but then so does computer gaming ;)

Westernization sweeps accross all countries though, and it is no longer 
vogue to be so self centered.   This will help with the most overt types of 
hatred.

Which is downright annoying.

Sometimes you need to make a statement about a local troll.

Dear Mr Troll,

There are GNU implementations of JVM and compiler.

And just because Sun's Java is not GNU does not mean it is not free.

File read from stdin and printed to temp file are not identicial?

[Jean Luc Truchtersheim]

Hello,

I am trying to read from stdin and dump what's read to a temporary
file. My code works for small files but as soon as I have a file that
has, e.g., more than 300 lines, there is always one and only one line
that is truncated compared to the input.

Here is my code:
#-
#! /usr/bin/env python

import sys
from tempfile import *

if __name__ == "__main__":
data = []
f_in = NamedTemporaryFile(suffix=".txt", delete=False)
for line in sys.stdin:
f_in.write(line)
data.append(line)
f_in.close
f = open(f_in.name, 'rb')
i=0
for line in f:
if data[i] != line:
print >>sys.stderr, "line 
%d:\nfile(%d):\"%s\"\narray(%d):\"%s\"" %
(i+1, len(line), line, len(data[i]), data[i])
i += 1
sys.exit()
#-

I feel that I must be doing something very stupid, but I don't really
know what.

Any idea?

Can anybody reproduce this behavior.

Thanks a bunch for any help.

Jean Luc.

Dear Fellow python users,

Many thanks for your help.

Those missing brackets were the cause of my problem.

Now my program works as expected.

Many, many heartfelt thanks.
