Re^3: partial match between 2 files

in thread partial match between 2 files

The following code shows one way to tackle this problem:

#! perl use Modern::Perl; my $file1 = 'amayaM vismayaM souraM kamalZ'; my $file2 = 'amayamAn vismayamAn souramA kamalAni'; my %words1 = map { $_ => undef } split /\s+/, $file1; my @words2 = split /\s+/, $file2; for my $word2 (@words2) { for my $word1 (keys %words1) { my $stem = substr($word1, 0, -1); my $len = length $stem; if (substr($word2, 0, $len) eq $stem) { say $word1, ' -> ', $word2, ' -> ', $stem, '+', substr($wo +rd2, $len); last; } } }

Output:

19:21 >perl 415_SoPW.pl amayaM -> amayamAn -> amaya+mAn vismayaM -> vismayamAn -> vismaya+mAn souraM -> souramA -> soura+mA kamalZ -> kamalAni -> kamal+Ani 19:22 >

Hope that helps,

[marioroy]: Perl is so much fun.
[Discipulus]: Tanktalus i recently started a Meditation about marioroy's MCE suit of modules, but is even better to see a practical question answered than responses to my meditation
[Discipulus]: good night mario!
[Tanktalus]: yeah, I saw you post about MCE - the concept looks really really cool. I wonder how well it plays with Coro :)
[Lady_Aleena]: Hi guys. I asked this earlier but got no answer. Why is this dying at -exec: my @music_times = qx(find ~/Music/Albums/ -type f -iname '*.mp3' -exec mp3info -p "%S\n" {} \;);
[Lady_Aleena]: The error find: missing argument to `-exec'
[Discipulus]: Tanktalus we will be glad to have you here more frequently, tho ;=)
[marioroy]: Lady_Aleena oh I thought you found the error by adding -exec mp3info
[Tanktalus]: Discipulus: I should be working on an interview test right now. Well, I kind of am, but keep getting myself distracted :)
