Subject: Counting blocks of text
Message-Id: <0bcb26f5-71b4-4e2f-a4bc-c2d4bade1ed7@p1g2000yqm.googlegroups.com>
Hi,
I'm using Perl 5.8.9 for Mac 10.6.3. I am trying to parse log files
(log4j v1.2.4) and count identical blocks of text in my file. So
below is an example of the kinds of things I see in my log file
(notice that some blocks of text span several lines). I would like to
get identify the similar blocks of text and get a count of how many
times each occurs in the file. Any ideas how I can do this?
Thanks, - Dave

You post hundreds of lines of errors, and don't include the last 33..
Very thoughtful. Next time, there's no need to post that many lines,
just post a few, showing different errors.
You don't say what you have already tried, but before you start
to write the code, first you need to define what you want to look
for in the file, that would constitute an error. e.g. does every
error start with 'ERROR '??, Does it start with a capital
letter?, etc.
Then you have to open the file and look for when that happens,
and keep track of the error and how many times it happened.
There are different ways to do it, but in general you'd:
open the file.
while you read the file, possibly line by line....
if the line contains the indicator of a new error.
if there was already a previous error that was found, then
store that previous, error.. maybe in a hash, and
increment the count.. e.g. $hash{ $error }++;
store the line as an error. $error = $_
else append the line to the previous error e.g. $error .= $_
close the file.
Be sure to capture the last error.. $hash{ $error }++;
Iterate through the keys in %hash, which are really the text of the
error, to find the error and how many times it occurred.

Hi,
I read from a book that "for" is actually "foreach". And foreach is
preferable in Perl. I can understand foreach is better if the counting
is from 1 to n. But what if the count start from 2 or 3 or more, how
can we use foreach in this case?
Thanks

They're equivalent, yes.

I think it's more accurate to say that Perl-style looping over lists
is preferable over C-style loops with three arguments. Iterating over
the items in a list is a very common operation in Perl, and Perl-style
loops provide a more elegant way of doing that.

One way would be to use the range operator:
foreach my $i (30..300) {
# Do stuff with $i
}

The perlsyn manual page have a scetion called 'For Loops' describing
C-style for loops and a section called 'Foreach loops' describing the
'iteration over a list value' functionality.
It also says that the"foreach" _keyword_ is actually a synonym for the
"for" _keyword_ and that Perl executes a "foreach" statement more
rapidly then i would the equivalent "for" loop.
So based on the official documentation the terminologi is murky at
best and it is not quite unacceptable to talk about 'foreach being
prefeaable to for'

It's more accurate to say that 'iteration over a list' executes more
rapidly than a C-style loop, regardless of which keyword one happens
to use for either one.

I agree. Since it's very common to write foreach() for list iteration
and for() for C-style loops - as you point out above, even perlsyn is
written that way - it's not *quite* wrong to say that foreach() is
preferable. It's not 100% accurate, though, since it isn't the keyword
choice that makes the performance difference.

That is, if I write "for my $i (1..1000000000)" I can be sure that perl
will not start by building a list of a billion entries?

that used to be the case in much older perls but today (i dunno when the
change was made but it was a good while ago) it will do an internal
iteration of large ranges.

The solution is as follows, why I include the commented lines is to show
that I did try debugging myself in order to understand the complex data
structures used in Perl.
my %absent = map {$_ => 1} keys %Priseq;
#foreach $key (sort(keys %absent)) {print $key, '=', $absent{$key},
"\n"; <STDIN>;}
delete $absent{$_} for @ids;
# foreach $key (keys %absent) {print $key, '=', $absent{$key}, "\n";
<STDIN>;}
#foreach $key (@ids) {delete $absent{$key};}
#foreach $key (@ids) {print $key, "\n"; <STDIN>;}
#foreach $key (keys %absent) {print $key, '=', $absent{$key}, "\n";
<STDIN>;}
foreach $key (keys %absent) { print OFP ">$key\n$Priseq{$key}"; }
#print ">$key\n$_\n" for @Priseq{keys %absent};
# if exists key

The Posting Guidelines say that you should not quote .sigs,
yet here you are, quoting sigs.
What are we supposed to think?

Nobody asked you to dump the whole code or big data files!
You were asked to post a short and complete program that illustrates
the problem you are having.
(Note how I made a short and complete program for you to run, you
should be able to do that for us too.
)
You were not asked for the actual program that you are working on.
You should make a new program that contains just the parts needed
to illustrate the problem that you are having.
If you are reading the file contents OK, then you should not show
code that reads the file contents for example.
If your code reads a file into an array, and that part is working OK,
then just post code that initializes the array to the same values it
would have gotten if you read them from a file.

That is because there ARE NO REFERENCES in the code in this thread.
I can't even remember what your question was anymore...
