Hi folks,

Time for the Second Release.

What's new:

- a very cool debugger
- a Scripts menu, representing the contents of a folder
- a completely rewritten object browser
- a "post mortem" option in traceback window
- it's packaged as a self contained applet
- a manual
- lots of little things that I am already so much used to
  that I can't seem to remember them all


Go straight to http://starship.skyport.net/~just/ and check it out!

Message-ID: <v01530500b08440bd7a6c@[209.48.225.130]>

Since Jack is out of town most of this month, let me send this to the list...

I've just installed v1.5a4 on a 7300/200 running OS8.  Most of the
installation seems to function but NumPy is having problems.  I initially
had path problems but they seem to be fixed (I do still have the 1.4
version in a separate directory).

import test.autotest seems to have function as described in the README file.
The general testall.py routine generates a number of problems which I have
been unable to redirect to a file for study.

The test_all.py program fails early on with an error (text below).  I even
get errors with commands as simple as import RandomArray.

Here's a sample from test_all.py:

>array([1, 2, 3])
>array([ 1. ,  2.3,  4. ])
>array([ 1.+0.j,  0.+2.j,  3.+0.j])
>array([ 1.,  2.,  3.],'f')
>array([[ 1,  2],
>       [11, 12]])
>(2, 0)
>zeros((0,), 'l')
>array([[0, 0, 0],
>       [0, 0, 0]])
>array([[1, 1, 1],
>       [1, 1, 1]],'s')
>array([0, 2, 4, 6])
>array([ 0. ,  0.5,  1. ])
>array([1, 2, 3],'b')
>array([2, 3, 4])
>array([5, 4, 3, 2, 1, 0])
>3
>array([ 2, 12])
>array([3, 2, 1, 2, 3])
>array([[ 3,  3,  2,  2],
>       [13, 13, 12, 12]])
>array([[ 1,  2],
>       [ 3, 11],
>       [12, 13]])
>array([[0, 1, 2],
>       [3, 4, 5]])

and here's a simple method of inducing problems:

>Python 1.5a4 (#21, Oct 10 1997, 15:40:54)  [CW PPC w/GUSI w/MSL]
>Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam

>>>>

The paths look okay.  It's obviously finding the libraries in the right
place but then it chokes.

Any suggestions?

Thanks,

I have confirmed this error. It also occurs in 1.5a3 with which Jack
included a compiled Numpy. This looks to me to be simply a change in how
exceptions are returned. The test code expected a certain error and the
format of the returned error string changed so it bombs out. It appears
that the change is in the string "<class ValueError at 39f2e20>".

I also confirmed the error with RandomArray. This comes from converting a
float that is larger than a signed integer can hold. Must be that 1.4 used
an unsigned int in this case?? This definition of seed() in RandomArray
seems to work.

def seed(x=0,y=0):
	if x == y == 0:
		import time
		t = time.time()
		x = long(t)
		y = long((t-long(t))*1000000)
	ranlib.set_seeds(x,y)

This may be a silly question, and I have not been able to find
any related postings in the archive, but is there any way to
prevent the console window from appearing when launching
a Python applet made with 'mkapplet'?  If that is not possible,
is there a way to remove it shortly after launch?  

I'd like some of the little utilities I've written to run more 
invisibly.

Any help would be greatly appreciated.

Thanks,

There is an option when dropping an applet onto EditPythonPrefs that says
"delay console window until needed", but... it doesn't work. It's fixed
since 1.5a3.

Subject: [PYTHONMAC-SIG] need socket error codes
Message-ID: <l03102805b08cf11871b1@[132.239.105.111]>

I'm trying to get Sam Rushing's "asyncore" module to work under MacOS.  It
looks like it just needs some constants, since on the following code...

---
import os
if os.name == 'nt':
	EWOULDBLOCK	= 10035
	EINPROGRESS	= 10036
	EALREADY	= 10037
	ECONNRESET  = 10054
	ENOTCONN	= 10057
else:
	from errno import EALREADY, EINPROGRESS, EWOULDBLOCK,
ECONNRESET,ENOTCONN
---

we get an "ImportError: No module named errno".  Apparently WinNT doesn't
have an "errno" module either, so Sam has hardcoded some constants; we need
only to do the same for MacOS.  But I've poked around in the socket module
and can't seem to find any such constants.  Can anyone help me out here?

Many thanks,
-- Joe

I am sure that this is not a good thing to do. But, I have gotten
monitor.py to work by changing 

if os.name == 'nt':

to

if os.name == 'nt' or 'mac':

I haven't used many of the other modules, but monitor.py seemed to work
fine.

All these except EWOULDBLOCK are in macerrors.py. You can check them in
errors.txt in Mac-->scripts to see what is available and their values.

If I have python and various other applications open on my Mac,

waits periodically to look for events, like mouse motions.  In
particular for a simple thing like:

for i in range(100):
  for j in range(50):
     printj=j
  print i,printj

the execution (printing) slows down and may even come to a hault part
way through if I don't do something like wiggle the mouse.  The
situation is even more dramatic if I click on another application's
window to make it active.  Can someone explain what is going on and if
there is a way to fix this?

I am running Python 1.4 on a powerbook 5300, OS 8, but I have observed
this with 1.4 running on other macs as well; I have no experience
with other versions of Python.

Message-ID: <3470AC70.188E7FD0@digicool.com>

I've been wanting to do this for a while, but now I might actually have the
time and motivation.  It would be a very good thing, I think, to bring Bobo to
the Mac.  Bobo code is some of the most portable CGI code since the CGI Module
publisher takes care of many of the nitty-gritty system interface and
publishing details.  Bobo would also work well with the Mac since most Mac CGI
applications are a long-running process.

When the first MacCGI support for MacPython came out, it was stated that an
effort would need to be made to make it more coherent with UNIX (like the
environment variables for instance).  Has there been any effort on this?  The
CGI Module Publisher can easily convert Mac CGI variables to the more common
Unix-ish ones.

Does Python for the Mac provide any support for grabbing video

Message-ID: <199711201654.RAA41052@euro.apple.com>

Hi all,

I'm using Python with success for building CGI scripts on the Mac.
I have, however, a problem with the classic >32K size limit when returning
big chunks of info.

How can I send more than 32K to a browser as a result of a CGI program?

Many thanks
Tasselli Marco

I can't believe that this would be a Python problem (what error
message do you get?).  You may have to read your HTTP server's
documentation.

I think the AE interface only lets you send 32k at a time.
The sdoc event handler should return the string <SEND_PARTIAL>  to 
WebStar and it will keep the connection open and expect more data to 
arrive.

Subject: [PYTHONMAC-SIG] German Umlauts and HTML
Message-ID: <v01510102b09f473340dd@[194.94.223.157]>

I have written a little Python-Scripts to generate automatically HTML-pages
from a database (FielMaker). But it's a german database and it includes
German Umlauts. I wonder if someone has written a modul for converting
umlauts to HTML-code. I can wirte it with a lot of if ... then ... else ...
code by myself but I think it's more a Job for the grep-module (but I
haven't work with grep until now). Thanks for every help (and excuse my
poor english).

If speed isn't a big concern you might try this little item...

from string import join

def latin1_escape(s):
    sl = map(None, s)
    for i in range(len(sl)):
        ordinal = ord(sl[i])
        if 160 <= ordinal <= 255:
            sl[i] = '&#%d;' % ordinal
    s_html = join(sl, '')
    return s_html

s = 'Some odd text: \321 \352 \361'
print s
print latin1_escape(s)


If you have 1.5 then I can think of a faster implementation.

You're welcome (and your English is better than my German;-)

I've checked at two of the locations for this and have found no Python-sign :^)

No, sorry, and it'll be a while longer:-( I've been away for 5 weeks,
and on top of that I've spent the last week in bed with 40 degrees
fever and some stupid infection (I even had to cancel a pretty
important gig with my band:-( ). It appears to be under control
(keeping my fingers crossed...) but I have a couple of "real-work"
deadlines for the end of the year too, so I'll have to do a bit of
scheduling and shuffling before I can give an estimate. It could well
be that I could have 1.5b1 out by the end of next week, but it could
also take significantly longer. As soon as I have a more firm idea
I'll let y'all know,
