Can't install Inline::Java
Hi all, I just tried to install Inline::Java from CPAN and it didn't work. The install process just stopped after some time. When I tried it the second time it stopped again at the same time. There was no error message or anything, it just stopped. Here is the output from CPAN when I ran it the second time, I hope one of you can help me. cpan[4] install Inline::Java Running install for module 'Inline::Java' Running make for P/PA/PATL/Inline-Java-0.52.tar.gz Has already been unwrapped into directory /home/alekoe/.cpan/build/Inline-Java-0.52-lSMcKs Has already been made Running make test make[1]: Entering directory `/home/alekoe/.cpan/build/Inline-Java-0.52-lSMcKs/Java' make[1]: Leaving directory `/home/alekoe/.cpan/build/Inline-Java-0.52-lSMcKs/Java' PERL_DL_NONLAZY=1 /usr/bin/perl -MExtUtils::Command::MM -e test_harness(0, 'blib/lib', 'blib/arch') t/*.t t/01_init.t Perl version is 5.01 Inline version is 0.46 Inline::Java version is 0.52 J2SDK version is 1.6.0_0, from /usr/lib64/jvm/java CLASSPATH is empty t/01_init.t ok t/02_primitives.t .. ok t/02_primitives_1_4.t .. ok t/03_objects.t . ok t/04_members.t . ok t/05_arrays.t .. ok t/06_static.t .. ok t/07_polymorph.t ... ok t/08_study.t ... ok t/09_usages.t .. ok t/10_1_shared_alone.t .. ok t/10_2_shared_start.t .. 1/3 -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/

Re: basename question from learning perl
Hi Jim, Jim Green wrote on 01/17/2010 05:25 PM: my $name = /usr/local/bin/perl; (my $basename = $name) =~ s#.*/##; # Oops! after substitution $basename is supposed to be perl but why it is not /local/bin/perl? will .*/ matches longest possible string? Yes it will match the longest possible string. To understand how this works (and how to avoid this behaviour if you don't want it) look into the concept of greedy regular expressions.

eval and next
Hi all, I have a Perl program where I use eval to catch errors. As they are Java errors (via Inline::Java) I want my program to continue and just log the errors somewhere. My problem with this is, that I use the eval within a loop and I also use next in this loop to ignore some special cases. But now, whenever the next is triggered I get a warning like this: Exiting eval via next at ad_hoc_stats.pl line 204, GEN6 line 5421. Googling the message I found this thread on Perlmonks http://www.perlmonks.org/?node_id=104789 But that does not seem to be about the same problem. I know that next is executed for the enclosing for loop and not for the eval block. That is how I want it. I tried naming the for loop to show perl that I know what I'm doing but the warning persists. Is there some recommended way of doing this, so that I won't get a warning every time the next is triggered? I hope my problem is clear. If not, I could provide some sample code as well. bye Alex -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/

You never close this opening curly bracket. That's probably the problem.

Re: Simple regex question
You wrote on 05/19/2009 03:18 PM:
Simple question for the regEXperts out there...
I have a string that is always in the format: a.nn+x.y
a is always 5 chars
n can be 1 or 2 digits
x can be +/- (with sign), 1-4 digits
y is always positive (no sign), 1-4 digits
The best I can come up with on the fly would be something like this:
---
#!/usr/bin/perl
use strict;
use warnings;
my @test = ('A123C.11+002.001','FC32G.2-1.0','12B15.01+2145.15');
foreach my $item (@test)
{
print $item\n\n;
($a,$n,$x,$y)) = $item =~ /(.{5})\.(\d\d?)[-+](\d{1,4})\.(\d{1,4})/;
my ($lengthx, $lengthy) = (length $x, length $y);
print a = $a, n = $n, x = $x, y = $y, length x = $lengthx, length y =
$lengthy\n;
}
---
But the real experts can probably compress it much more still.

snip
As of Perl 5.8 \d no longer matches [0-9]. It now matches any UNICODE
character that has the digit property. This includes characters such
as \x{1815} (MONGOLIAN DIGIT FIVE). You must use [0-9] if you mean
[0-9] or use the bytes pragma[1] to return the old meaning of \d (but
this breaks all UNICODE processing in the scope you declare it).
Oh, I didn't know that. Thanks for pointing that out.
But in most scenarios \d will still work, right? I mean, how often do
you actually encounter the Mongolian Digit Five in real life data?

Re: Can't Retrieve Data From foreach block
Hi,
You wrote on 03/30/2009 04:07 PM:
How can I retrieve data loaded into an array within a foreach block?
The array is defined outside the foreach block and is not the indexing
array of the foreach loop.
I ran your code and it works fine here.
I did however have the same problem as you at first, so maybe you made
the same mistake I did at first.
foreach (@lines) {
@line = split /\t/, $_;
push @lastnames, $line[2];
}
Are you sure that the split (always) produces an array with three
elements? In my test array it only had two a la alex\tkoenig, which
resulted in the error messages you described.
To test this you could insert a print line after the split. Something
like this.
print $line[0]\t$line[1]\t$line[2]\n;
