Perl Weekly Challenge 269: Bitwise OR

https://blogs.perl.org/users/laurent_r/2024/05/perl-weekly-challenge-269-bitwise-or.html

I want to repeat a process for every key in a hash, with numeric keys. So there are 3 possibilities, with 3 if, and each one compares the value of the index of an array, so that if that position eq to "sp", "sp2" or "sp3" it will search in a document some value so then it can be printed. It doesn´t work and every times gives me only one value, i would like to get the values that correspond with the hash. For example the hash could be %grupos=(1,'A',2,'G',3,'J')

and the array @hibridaciones=("sp","sp2",sp3")

The document .txt (simplified) is:

HS0.32 CS0,77 CD0.62 CT0,59 C10,77 C20,62 C30,59 OS0.73 OD0,6 O10,73 O20,6 NS0.75

The code is:

open (covalencia,"<", "cov.txt") or die "$!\n"; print keys %grupos; keys %grupos; foreach my $z (keys %grupos) { print "\n$z\n"; if (@hibridaciones[my $z-1] eq “sp") { while (my $line = <covalencia>) { if ( $line=~/C1/) { $line =~s/C1//; $radio=$line; print "\n$radio"; } } } if (@hibridaciones[my $z-1] eq "sp2") { while (my $line = <covalencia>) { if ($line=~/C2/) { $line =~s/C2//; $radio=$line; print "\n$radio"; } } } if (@hibridaciones[my $z-1] eq "sp3") { while (my $line = <covalencia>) { if ($line=~/C3/) { $line =~s/C3//; $radio=$line; print "\n$radio"; } } } } close (covalencia);

Making a Super Cal if Rage Will Stick Ex Paella Down Us

https://blogs.perl.org/users/saif/2024/05/making-a-super-cal-if-rage-will-stick-ex-paella-down-us.html

On this site: https://codegolf.stackexchange.com/questions/246845/convert-json-object-of-directories-to-list-of-paths

There is an interesting perl solution but I'm trying to wrap my head around it and am baffled.

map/}/?/{/&&say($s)..$s=~s|[^/]+/$||:($s.=s/"//gr."/"),/{?}|".+?"/g When I do a simple test: my $s = <some json string> .. the map above I don't get any output. Thanks in advance 

Convert JSON object of directories to list of paths

Task The input consists of a JSON object, where every value is an object (eventually empty), representing a directory structure. The output must be a list of the corresponding root-to-leaf paths.

^{Code Golf Stack Exchange}

I have a bunch of files that I am parsing out a simple tag
<institution content-type="division">(.+?)?<\/institution>

Everything is going fine until I hit this result:
2) School of Chemical & Biomolecular Engineering

This is complaining because it thinks the ) is unmatched. How do I get it to accept whatever is in the capture? I tried playing around with \Q and \E but that isn't working. For clarity, I won't know what is in this tag, it could be anything at all and the tag is simple enough that I don't want to use some XML parser.

This week in PSC (145)

Hi! Asking for a wisdom here...

We have a module that modifies signal handler $SIG{__DIE__} to log information and to die afterwards. Hundreds of scripts relied on this module which worked fine in perl 5.10.1.

Recently we had the opportunity to install several Perl versions but unfortunately a large number of scripts that used to work with Perl 5.10.1 now behave differently:

• Failed in 5.14.4: /home/dev/perl-5.14.4/bin/perl -wc test.pl RECEIVED SIGNAL - S_IFFIFO is not a valid Fcntl macro at /home/dev/perl-5.14.4/lib/5.14.4/File/stat.pm line 41
• Worked without changes in 5.26.3: /home/dev/perl-5.26.3/bin/perl -wc test.pl test.pl syntax OK
• Worked without changes in 5.38.2: /home/dev/perl-5.38.2/bin/perl -wc test.pl test.pl syntax OK

Many of the scripts can only be updated to 5.14.4 due to the huge jumps between 5.10 and 3.58; But we are stuck on that failures.

Was there an internal Perl change in 5.14 which cause the failures but works on other recent versions without any update on the scripts?

Cheerio!
