when i try to run the following program, Python complains about some

it would be nice if the two working programs do not use some package.

I understand your frustration - emacs can be (and easily is) pretty
intrusive. It's meant to be considered as a way of life. If you spend
enough of your time writing code so that you can accept the emacs way
of life, then your life really will become easier. On the other hand,
if you just dabble at a piece of code every now and then, then emacs
may well be too intrusive (by default, at least). Of course, as emacs
is pretty much completely customisable through writing snippets of
elisp, you could tell emacs to keep out of your way. But then, writing
this amount of elist I guess would mean you're doing so much with emacs
that it is your way of life, so we have a slight chicken-and-egg
problem here.
Mind you, the same seems to be true for every large piece of software:
most fullblown GUI IDEs I've seen (like NetBeans for Java) are the
same -- and even MS Word is the same, if you just want to write a simple
one-page note. So, if you're spending a lot of your time with some
computer-related activity, get good tools for that, and learn to
utilise them. After the initial shock, they will ease your work. If
you're just dabbling occasionally, use as lightweight tools as you
can get away with -- they'll not be in your way.

Don't look for perl/emacs book. Look for a emacs book: because it's emacs
anyway, it'll be more or less the same. Learn elisp to some extent (more
than just copy-paste). Have a look in the cperl-mode.el file for insights
into how/why cperl mode does something in the way it does (and also to
possibly find some useful settings that are not documented for a reason
or another).
But as said, I understand your frustration. For the time being, I'm not
spending enough time writing code to really use Emacs, so I've reverted
to the small tools. Back when I did write more code, I did find emacs
a good tool - but did remember having a similar frustration as you
describe.

I'll start you off :
1. download the file 'mode-compile.el'
http://www.tls.cena.fr/~boubaker/distrib/mode-compile.el
and store it in your site-lisp directory.
2. download the file perl-54-info.tar.gz from CPAN and
extract the files and store in your 'info' directory.
3. in your info directory open up the 'dir' file and add
the following line at the bottom of the file.
Development
* Perl Modules: (pm).
* Perl - Practical Extraction and Report Language: (perl).
(be careful that the very last line in the 'dir' file is
a blank line otherwise it won't be read by Emacs)
4. in your site-lisp directory create a file 'default.el'
(you will have to look at variable exec-path to point
to your perl and Emacs binaries)

an interesting problem so developed now is to write a function that
generate test cases for the purpose of testing performance. (just for
fun)
the design of this function could be interesting. We want to be able to
give parameters in this function so as to spit out all possible screw
test cases. First of all, a range of n (some millions) numbers. Then, a
fraction that specifies the percentage of these number are equivalent.
1 being all equivalent. 0 being all "distinct" (having only one
equivalent member (since the input comes in pairs)). Then we want to
have a parameter that says something like the sizes of the equivalence
groups. Suppose 50% of number are equal among themselves (i.e. have
more than one equivalent member). 1 would be all in one group. 0 would
mean all partitions have size 3 or 2. (there are more to it here...
since this is a distribution) ... Then, we need to turn this range of
integers into pairs. That's something more to think about.
So with this function at hand, we'll be able to say for sure which code
performs better (and under what type of input)
the Order notion in computing mathematics is fairly useless for finer
details.
PS it is not trivial to design this pair generating function. I don't
know if the above is on the right track, but essentially we want to
categorize the type of inputs according to the mathematical operational
performance aspect of partition by equivalence, and distill them into
parameters.
another func to write is one that canonicalize the output. Such as
sorting. So that all results can be compared simply by = in Python.
failing to design a elaborate pair_gen, we can just have pairs of
random numbers. But exactly what nature is such input... is more to
think about.
(in my original application, each number represent a computer file,
there are up to tens of thousands of files, and much less than 0.1% is
same as another, and for files that are same, each equivalent group
number no more than 10 or so.)

You must be running 2.3. If you persist in running 2.3, put the

import sys
PY_VERSION = sys.version_info[:2]
if PY_VERSION == (2,3):
from sets import Set as set
from sets import ImmutableSet as frozenset
That will get Reinhold's gadget working under 2.3. The bearophile's
function uses collections.deque which is built-in to 2.4.

Look at the newsgroup again. By my count there are apparently-working
versions from SIX people: Reinhold, bear.+, Brian Beck, David Eppstein,
yourself, and me. Only David's uses stuff that's not in the Python 2.4
off-the-shelf distribution.

I noticed it too, I think at least a week back. There is still some
weird artifacts that show up if you view with google, but they are not
there with other news readers or even google's show original option.
I don't know if I really believe this whole 'killfile' thing. I think
it's a myth, like skinny people saying that they don't watch what they
eat. I think that the temptation to see what dumb newbies like me and
worse are posting is too great to filter out. How boring would it be
just to read the proper postings?
People could write a filter that runs code in usenet postings through
perltidy just so all formatting is to their liking.
This would be a great feature to be built into a Perl newsreader, a
program-as-module built on CGI::Application or something like that.

It was certainly not a myth in my case. Also, it's not necessarily about
clueless posters but simply about postings with scrambled code snippets
that I cannot be bothered to decipher.

It's not that there wouldn't be enough other postings in this group.
Still plenty to read if a certain amount of them disappears.
Apart from that, a perltidy filter isn't as easy as it may appear. First
you have to identify which parts are code and which are text. They are
usually interleaved. Furthermore, you have to deal with long lines,
especially comments at the end of the line that wrap around. Perltidy
cannot handle this.

Hi, there:
This is not C++, but I think it will get some quick response for my Laptop

I expect my notebook doesn't inhibit me from editing digital pictures due to
LCD displays.
What does the "Maximum Resolution1024x768" and "Max resolution (with max
video
RAM)2048x1536" mean?
If I order this machine with RAM upgraded to 512MB, will I get a resolution
of 2048x1536
anyway?
Thanks.

Definitely OT, but I'd assume the first spec is the number of physical
pixels availalbe in the laptop's display whereas the second is the max
resolution the laptop's video output could handle if hooked up to a
suitable external display if you have purchased the maximum possible
video RAM.

Subject: Importing records with both space and quoted text qualifiers...
Message-Id: <111fofbqjcv91ab@corp.supernews.com>
Can someone advise me of how to input a file into perl that has quoted
text qualifiers? An example lines is as follows:
1) Field_1 Field_2 "This is field 3" This_is_field_4 "the 5th field" field_6
2) one two "This is 3" four "This is 5" six
Normally I would read the file into an @array variable. Then each
line, I'd use @fields = split(/ /,$eachline). From there I would use
@fields[x] for each field.
My question is, is there a easy (or standard way) to use some variation
of split() to, not just split the recorders into space files, but to grab
the contents of the text qualified fields.
Thanks in advance for anyone that has comments or suggestions. Please
advise me if my question isn't clear.

This is FAQ: "How can I split a [character] delimited string except when

The whole point of the FAQ is that you should check it bafore you ask a
question so that the discussion fora are not overrun with the same
questions over and over.

Thank you, Brian. Believe me, I had studied the docs, the faq and the
board. My problem is that I was having a little difficulty in the
description. Your input made the description very clear and easy to find
the solution.
I'm aware that a standard (of is it all) csv files are comma
delaminated (or separated). The lines/records I'm working with are space
separated, except when in the quoted text qualifiers. For your information
I'm writing a script to analyze a web access log output.
The example I found in the faq works perfect with comma separated
records. I'm spending time now trying to figure out which commas to remove
from the following to replace with what would specify the separator as a
space.
----------------
@new = ();
push(@new, $+) while $text =~ m{
"([^\"\\]*(?:\\.[^\"\\]*)*)",? # groups the phrase inside the
quotes
| ([^,]+),?
| ,
}gx;
push(@new, undef) if substr($text,-1,1) eq ',';
----------------
Please excuse some of my method of definition, but if someone could
suggest how change the above code to use the space character rather than the
comma, this would go far in helping me to solve the problem.
Thanks again for any suggestions or comments.

I missed this discussion before, but the blead version of the FAQ
does have an alternation example, but punts to Mastering Regular
Expressions for the full details on why alternation can be really
slow. If anyone has a better answer, they can post a patch. :)

Perhaps (not sure about this) it would be faster (fewer steps?)
to use one of the *newer* (than heapsort) priority-queue methods,
eg splay trees and the like?
(Or maybe no real difference?)

C is _not_ a strongly typed language. Sure, a newbie might
be surprised by @LIST being a list sometimes and the size of
the list other times. But C programmers--even experts--are
often surprised by the results of C's implicit automatic casts,
or it's ability to add two positive numbers and get a negative
without complaint.

But for a lot of non-"mission-critical" purposes, perl is great.
Heck when it comes to mission-critical, I am highly unlikely to

Sometimes--not always--people who speak of "hand-holding"

However, is it still true (I haven't done C in ages)
that in C you can compile a function call without first
compiling the declaration? In which case the compiler
will assume the result is int, and stack as many parameters
as you give it. If it turns out to actually return a float,
"that's life."
If it turns out to pop from the stack more params than
it was called with, that's death. :-)
