I've been playing with erlang lately and have really enjoyed it. I wish I
had more time to go stuff like this erlang workshop but I never seem to have
the time.

Erlang has a very minimalist syntax and the pattern matching really suits me
a lot. It's certains stretched my thinking considerably.

I've made a lot of progress with the BackPAN indexing stuff and have a

Unfortunately that is my wifes birthday so I can't be there but next time I
have a talk I'm thinking about giving. I've been playing with CouchDB and
released to CPAN a CouchDB module.

Subject: [Chicago-talk] cpan problems in Fedora 9
Message-ID: <48C91228.2030503@alanmead.org>

I know this isn't a Fedora mailing list but if any of use F9, I think 
you may have solved this problem and some of you may know what level of 
support Perl has in Fedora these days.

I've previously used FC3 & FC4, and in F9 the cpan script is apparently 
split off as a separate rpm (which is inconvenient).  When I tried to 
use yum to install the perl-CPAN module, I get an error message "Error: 
Missing Dependency: perl = 4:5.10.0-20.fc9 is needed by package 
perl-CPAN-1.9205-20.fc9.i386 (fedora)" which is funny (ha ha) because 
the installed version of Perl is 5.10.0-31.fc9...  I don't know whether 
I'll have problems later? but I think I have solved it by manually 
downloading perl-CPAN and forcing it to be installed.

I was also wondered whether anyone had a thought about whether it's 
better to use Fedora's pre-compiled modules or just use cpan?  I guess 
the pre-built DBI/DBD modules have been useful, but a lot of the modules 
I might use are not there so I've always just relied upon the cpan 
script in the past.

Fedora maintainers hold the position that you're SOL if you're trying
to install things from CPAN yourself.  You should always look to the
fedora repositories first to see if a package is available there; as
it's made specifically for your operating system, and you don't have
to worry about compiling.

Subject: [Chicago-talk] undef values in arrays.
Message-ID: <2379dacc0809111930s6e24ac6bt670ff4dd9f6b98db@mail.gmail.com>

This statement:
 print $Count . " " . join(", ", @a) . "\n";

Produces this errors message:
Use of uninitialized value in join or string at ./TransferTables.pl line 4154.

The array is a result of this statement:
my @a = $sth_s->fetchrow_array

I presume I have a NULL value in my database and it come back as a
undef in the array.

I rarely allow NULL values in a database so I don't know that from experience.

Anyway, Is there a graceful way to replace the udef values in @a with
the string "<NULL>"?

That way I will see them and I will not get the warning message.

Thanks,

Don't presume.

use Data::Dumper;
print Dumper( \@a );

@pretty = map { defined $_ ? $_ : '<NULL>' } @a;

Sounds like we have a talk... I can do my Open Flash Chart and Perl
talk too if there is time and interest.  I'll get the announcement up
on the website soon.  I'll probably also create an evite or meetup
thing for people to RSVP.  Any preference?  My only preference is that
I don't have to pay for it :)

Given the issues with RH's Perl I'd use
one built from scratch for all of my own
work.

What I've always done is install my own
perl in /opt/perl5 and keep it up to date
with -MCPAN. That leaves the vendor's
perl in place where only their updates
touch it: neither of us can break one
another.

Error or warning?
Using an undef shouldn't be fatal unless
someone makes it explicit (as in defined or die...
or an __WARN__ handler that dies).

Yup.

> that from experience.

Yup. If you use Oracle there ain't no other way
since they don't provide the only reasonable
default for strings: '' is converted to a NULL.

If you use Postgres, MySQL, Sybase or something
else sane you can avoid this by using the empty
string as a default.

One way out is modify the query to include
"foo is not null" or

     @rowz   = grep { $_->[ blah ] } @rowz;

> Anyway, Is there a graceful way to replace the udef values in @a with
> the string "<NULL>"?

     my $null    = '<NULL>';

     my $rowz    = $sth->fetchrow_array( ... );

     for( @$rowz )
     {
         for( @$_ )
         {
             defined or next;

             $_ = $null;
         }
     }

> That way I will see them and I will not get the warning

Proably better off hacking the SQL to just
remove records with NULL values from being
processed and leave the warning (or more
detailed one with a key) for the records
missing values.

Yeah, if you haven't read this, you should: http://blog.vipul.net/2008/08/24/redhat-perl-what-a-tragedy/

Especially in the face of upgrading modules that are included by the vendor.  With my own perl, I can do whatever I want without worrying that I'll break anything else.

That's really a drag, but I ran vipul's test code and this bug seems not 
to be included in F9 for i386.

More likely they'll break you. Aside from
the known issues with RH, most of the perl's
in the distro's include threading and are
compiled with debug support (i.e., '-g').

Q: How often have you ever run gdb on perl?

Given the likely answer, why pay the price
for -g? I'd also rather strip the non-
essential symbols (for the number of time's
I'll be tracing core dumps of perl it won't
affect me).

Putting the stuff in /opt also allows me to
get it off of my root partition, which leaves
that much less to deal with in case of a
system recovery (or backup).

Which is GREAT if you really are running an
i386 processor... anyone with a 486-or-higher
CPU would want to compile their copy of perl
to take advantage of the last decade's
improvements in chip design.

Wow, we have a big group signed up for the meeting tomorrow....
exciting!  The main meeting room is taken because they are setting up
for an early morning meeting on Wednesday, so when you get to the
office (20 W Kinzie) go to the 7th floor.  There is an alternative
meeting space that we can use.  Also, I'm going to pick up some food,
so if you want to show up early (say around 6:30) there will be
sandwiches or pizza or something similarly cater-able.  See you all
tomorrow.

Message-ID: <d6105b7c0809251804mb77a70dm3ed89a01acb99502@mail.gmail.com>

Hi,
  I need to do it as part of unix command line invocation.
  I thought I knew it but after trying for almost one hour I am still
unable to get it right.
  Your ideas much appreciated.

       perl -pe 's/(\n)+/\1/g' inputfile
       perl -pe 's/(\n)+/\1/sg' inputfile
   are not working.

   I see the following reduces consecutive 'x' s to a single 'x'
   perl -pe 's/(x)+/\1/g' inputfile

   Not sure why it is not doing it for newline character. May be it is
very stupid mistake.

Thanks
VIJAY

Is it that the shell is eating your "\" chars?

Will:

 perl -pe 's/(\\n)+/\\1/g' inputfile

work?

Because $_ contains a single newline character, always.

Perhaps you want to simply delete any entirely blank lines..
.

  perl -ne 'print if /\S/'

Or even simpler:

  grep .

(That's grep, and a single dot.)

-p means read a line at at time, lines being text ending w/ "\n".  If you
want to eat the whole file, there's the 'slurpy' mode using the "dash zero"
command line switch
perl -0777 -pe 's/(\n)+/\1/g' unputfile

see perldoc perlrun:
-0[octal/hexadecimal]
specifies the input record separator ($/) as an octal or hexadecimal
number.
...
The special value 00 will cause Perl to slurp files in paragraph mode.  The
value 0777 will cause Perl to
slurp files whole because there is no legal byte with that value.

In theory:
perl -0777 -pe 's/\n+/\n/g' unputfile

would be faster/cheaper as you aren't asking to save the match (as you
already know what the replace is) but ...

Wow...that solves my problem.
Thanks Andy, Randall and Jay.
I am thrilled to get responses from you.

However, I would like to use the following one because I think it is
more readable.

     perl -pe 'BEGIN{undef $/} s/\n+/\n/g' inputfile

All this is doing is rejecting lines with nothing on
them:

     print -n -e 'print unless /^\n/'

This can also be written as

     perl -n -e 'print if /./'

Since since the '.' won't match a newline and you'll only
print lines with SOMEthing else on them.

Note: This isn't golf: depending on the size of your file
processing it by line can actually speed things up and
saves you from creating huge input buffers for no good
reason (see URI's description of Slurp for more). You
also have to examine fewer characters (just the first
one on each line) rather than searching and replacing
the entire input buffer.

Sorry for not being clear about the problem. The intention was to
replace consecutive 2+ multiple blank lines with 2 blank lines.

Today I checked-in some code like below that formats Oracle's spool output.

    perl -0777 -pi -e 's/^SQL>//mg; s/\n{2,}/\n\n/g' inputfile
    cat inputfile | mailx ....

and obviously giving credit to Andy in the comments and explaining about 0777.

Thanks
VIJAY

Why do people use a useless cat?

Why not just:

    cat inputfile | cat | cat | cat | cat | mailx ...

it's just about as wasteful?

Why do people use a useless cat?

I think they are Perlists from Windows' world, who should read some books about UNIX, such as Learning the UNIX Operating System, UNIX Power Tools, etc

Because they see things like this:

     All done. Patch successfully generated.
     To apply the patch to the system, proceed as follows:
     # cd /usr/src/linux
     # cat /scratch/DriverInstall/sk98lin_v10.61.3.3_2.6.25_patch | 
patch -p1

from a Marvell network driver. The fools who write
these don't understand *NIX or shell programming.
Having seen it there they end up stuck with it as
the picture in their head: oh, cat, I get it now...

blech...

All you are trying to do is remove blank lines.

     perl -n -e 'print if /./' $file

or

     perl -n -e 'print if /./' < $file

will do that with a minimum of command line
switches and regexen (not to mention cats).
