Subject: Can't get regex right
Message-Id: <pw2Sd.16432$Q84.1358959@phobos.telenet-ops.be>
Hello,
Been playing around with a regex that should help a substitute of part
of an html template. I can't seem to get it right though. Anyone sees
what I am doing wrong ? I might have been staring at it for too long
myself...
subsitute : $tmpl_cont =~ s/\[\[LIST\]\](.*)\[\[\/LIST\]\]/$token/g;
(the $tmpl_cont var holds a join of the template - I have checked that
already by printing it to the browser and inspecting the page source.
template = http://www.galleryscript.net/demo/layout/xlisttemplate.html
As I was not sure about the wildcard, I also tried :
subsitute : $tmpl_cont =~ s/\[\[LIST\]\]([.\n]*)\[\[\/LIST\]\]/$token/g;
Thanks for any help...

You probably need the /s modifier. If there may be more than one
occurrence of the [[LIST]] .. [[/LIST]] pair, you should also make the
regex non-greedy, i.e. .*? . Otherwise the /g modifier is redundant.

Because the . character is not special within a character class. [\n.]
represents only a newline or a literal dot.

Subject: Converting Word Control characters to an ASCII format
Message-Id: <1108924152.271594.263610@f14g2000cwb.googlegroups.com>
Hi,
I support a web application the customers use to update information
regarding various products.
A lot of times, they copy and paste from a Word Document into the
textbox in the provided form.
The cgi beind, reads in this data and stores it in an ASCCI text file.
When the product
information is updated, and this new information is displayed, all the
Word special
characters are displayed as ? (including the apostrophes, hyphens and
other stuff).
I tried dos2unix program to convert this, but it's not working. Is
there a Perl regular
expression out there which can do this job? So I clean up the text
before storing it in a
text file?
Thanks,

Well, it hurts a bit. Obviously the version with emacs 21.4 is broken,
and that hurts.
As for the version, I always need the latest version of all useful Linux
software. This is because I have been developing my own Linux directly
from the sources ever since kernel version 0.7 (? I ferget exactly, but
it's close). If I ever stop continually upgrading to latest versions,
I'd be overwhelmed. I could then only catch up by reverting to a
distribution.

Thank you very much for this! And thanks to all for thoughts and
empathy. I do try to only work on little bite-size bits of code at a
time and I am not a professional, but I would like to get in on the
whole emacs thing eventually. I read that the creator of emacs has a
big book out and there is another big one on lisp for emacs. I'll try
and master the tutorial stuff little by little and when I'm ready, I'll
get the emacs book.
Thanks again!

What is "this random pairs test"? What is xMax (nPairs isn't hard to
guess), and how are you generating your input data?<
merge2 and this random pairs test comes from the post by Brian Beck.
merge4 is the first in my last post. And merge3 isn't included (nor
tested) because it uses the original (slow) addArcs.
This is the simple test generator taken from his post:
xMax = 3000
nPairs = xMax*5
l = [[randint(0,xMax), randint(0,xMax)] for i in xrange(nPairs)]
For such high number of nPairs (arcs), the resulting graph usuall has
one big connected component, and few tiny debris... To produce a more
divided graph, nPairs have to be much smaller, like xMax*1.5.

I'm sorry, I don't see the attach... (just the different title).
John Machin:
>Only David's uses stuff that's not in the Python 2.4 off-the-shelf
distribution.<
Well, using already mede functions and classes is good, it avoids you
to reinvent things each time. Some of my versions too use my graph
library (for a problem like this I usually don't create stand alone
versions like merge6 and merge7). And my original point was adding one
graph data structure to the standard Python library :-]
I haven't tested the speed of David Eppstein version...
Anyway, this is a simplified version of merge6, that uses an indirect
graph g, instead of the directed graph, and avoids the use of chain:
. from collections import deque
.
. def merge7(l):
. # Undirect graph g creation:
. g = {}
. for n1,n2 in l:
. if n1 not in g: g[n1] = {n2:0}
. else: g[n1][n2] = 0
. if n2 not in g: g[n2] = {n1:0}
. else: g[n2][n1] = 0
. # Connected components:
. result = []
. visited = set()
. for root in g.iterkeys():
. if root not in visited:
. component = [root]
. visited.add(root)
. Q = deque() # A queue
. Q.append(root)
. while Q:
. n1 = Q.popleft()
. for n2 in g[n1].iterkeys():
. if n2 not in visited:
. visited.add(n2)
. Q.append(n2)
. component.append(n2)
. result.append(component)
. return result
It's a bit shorter and a little faster than merge6, memory used is
similar (there is only one dictionary, so there is only one
ammortization overhead of the dictionary, but it contains the sum of
both arcs, so the ammortization can be twice as big, so... memory used
can be the same).
(Usually BFS and DFS memory requirements are a little different; this
implementation uses BFS, and I think it uses a bit less memory than
DFS, but for this problem/test the difference isn't significative.)

The seller is overselling the ability of the machine. If the screen is
1024x768, it will never display anything higher than that on its on
screen. It may well be able to display 2048x1536 on its external
display, but you need to see how much video RAM it actually has. It's
pointless to state that the hardware is capable of more when it doesn't
have the RAM.

You may want to try Radio Shack if there is one in your area. I
recommend you not ask this in comp.lang.c++ as it will be completely
off topic over there.
Get the extra ram anyway if you can afford it, and ask about battery
life. Regarding the battery, they have Acpi::Battery on cpan.org, but
it's just for Linux. Imagine if something like that could support all
platforms?

The Text::CSV_XS module allows you to specify various separators etc. The
module is mentioned in the FAQ you claim to have read. I would suggest
reading the docs for the said module, and saving yourself some trouble.
Oh, by the way, please do read the posting guidelines for this group.

The faq mentions that TEXT:CSV_XS module. I guess I didn't make it
clear enough, but I thought I had expressed that an answer to how to
manipulate the example I posted would answer many questions about data
formatting.
I appreciate that you have taken the time to may your expressions. I
often point people to helping themselves when answering questions. I also
understand that something that is very clear to me might not be so clear to
someone else who reads the same time. Then if I take the time to express
the same thing in a slightly different way, some things (that was already in
the person's face) becomes clearer.
For your information, I not only did a lot of experimenting in trying
to decipher the FAQ, but I searched a lot though the message base before
posting. I was trying to find other examples where others might have asked
the same question. All the similar questions liked the missing link in my
mind, how to handle the space as the separator.
I didn't immediately explore the TEXT:CSV module because, I created an
example using the function I posted. I thought the function would have been
easy enough for a few gurus to read and respond on how to handle the white
spaces. This information would help me from other parts in my programs.
It'll actually answer quite a few questions that I haven't asked.
Again, I'm sure I'd eventually figure out how to change that function
from using the comma to using the SPACE as a separator. I thought of first
changing all the spaces to comma, then processing the line, then changing
the commas in the quoted fields back to spaces. Some of the problem with
that is there are actually commas in the quoted delaminated fields.
By the way, at present I found that changing most of the commas to a
string set as $sp="\s" was a start. However, it has glitches because I
can't tell which of the commas is a necessary part of the function or is the
designed delimiter.
I'm hoping that you (or someone will notice) that I am doing the
homework. I hope you'll remember when you got stuck while the answer was
right in you face. And if you know that answer, would actually post it.
The question is which of the commas in the following function should be
changed to the new delimiter, if for instance it was a colon, as in the
passwd file, or a space as in the web log file, or a comma as in a normal
csv file. In my current case can someone give me a suggestion on this
function?
(Where else should the $separator variable be placed?)
----------------
$separator = "\s";
@new = ();
push(@new, $+) while $text =~ m{
"([^\"\\]*(?:\\.[^\"\\]*)*)",? # groups the phrase inside the
quotes
| ([^,]+),?
| ,
}gx;
push(@new, undef) if substr($text,-1,1) eq '$separator';
----------------
Again, and as always, thanks in advance for anyone taking the time to
reply.

Don't take this the wrong way, show some respect, and try and compose
your messages in somewhat comprehensible English. I read and re-read
various parts of your messages, and I cannot even begin to imagine what
you mean by them.

Text::CSV_XS is what I suggested. There is no TEXT:CSV module. Text::CSV
is the pure Perl version of Text::CSV_XS.

Someone has already solved the problem you are trying to solve, and put
it in the Text::CSV_XS module. I have zero interest in even trying to
decipher that RegEx, because I like the transparency of being able to
say "this is the separator character I want to use" as in
my $p = Text::CSV_XS->new({ sep_char => ' '});

De-lamination is probably the process of peeling off lamination from an
ID card. What you want to say is "delimited". I am only pointing this
out because of the consistency with which you refer to 'delaminated'
fields.

Well, you were not there to help me, so I fail to see how this is
relevant to anything.

I did. I told you to look at the docs for Text::CSV_XS.

This is exactly the kind of thing Text::CSV_XS deals with.

It it confusing to use an .exe suffix on a Perl script.

Then write Perl. Show us what you have tried.
You call external executables with argument using system(). RTFM for
details.
But the real answer is that you should probably not do it.
Do not have the first script call the second.
Cut out the guts of the second Perl script and make it into a module
that is used by both scripts.

This is what happens, yes.
However, there are context-sensitive things in C which cannot be
circumvented. For example, you have to declare variables prior to first
usage.

Not necessarily. The only thing guaranteed is that those additional
arguments contain garbage. The following will most likely not segfault.
It even compiles silently (unless additional compiler warnings are
explicitly switched on):
#include <stdio.h>
#include <string.h>
int main (int argc, char **argv) {
bla("string");
}
bla (int i, char *string) {
printf("%s\n", string);
string++;
printf("%s\n", string);
(*string)++;
printf("%s\n", string);
return strlen(string);
}
