Translate the names of the dates using perl

corfuitl has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I have a perl code that recognises the name of the days and translates them into an other language. My code looks like:
next unless /(Sunday|Monday|Tuesday|Wednesday|Thursday|Friday|Saturday +)/g; #there is one file for evert language containing the translations open (SRC, "<db-dates/$src") or die "can't open file '$src' $!"; my @src = <SRC>; chomp(@src); for my $i (0 .. $#src){ $dayname =~ s/@src[$i]/@tgt[$i]/g } given($tgt){ when("fr_fr") { print $day" ; } when("it_it") { print $day" ; } default { print $day" ; } }
This script, recognises the days and translate them correctly, but I am not able to print the rest of the phrase. For instance, if the sentence is Today is Monday I want to print Today is lundi for french or Today is lunedi for italian. At the moment is translates only lundi or lunedi. Thank you in advance for your time.

    You didn't give us enough information. The code you gave us is far from complete (we don't see where half the variables come from), and you didn't provide a data sample. See How do I post a question effectively?.

    Unless you're writing in Perl 6, which you probably aren't, you should write $src[$i] instead of @src[$i]. $ is for single values (scalars), and @ for multiple values (lists or arrays), so when you get the single value $i out of @array, it's $array[$i].

    Reading a bit of documentation would be a good idea, and perlintro a good place to start.

    There are quite a lot of tools available to do this in a generic and reliable way from CPAN, but from what you describe, I think this comes close:

    my $tgt = "fr_fr"; my %day = ( en_gb => [qw( sunday monday tuesday wednesday thursday friday satu +rday )], fr_fr => [qw( dimanche lundi mardi mercredi jeudi vendredi samedi +)], it_it => [qw( day0 day1 day2 day3 day4 day5 day6 )], ); my %tr = map { lc $day{en_gb}[$_] => $day{$tgt}[$_] } 0..6; my $tr = do { local $" = "|"; qr{\b (@{$day{en_gb}}) \b}i; }; open my $fh, "<:encoding(utf-8)", "db-dates/$src" or die "$src: $!"; while (<$fh>) { s/$tr/$tr{lc $1}/ge; print; }

    It looks like $day contains the name of the day, and nothing else. You need to tell the program to print the "Today is".

    print "Today is "; given ($tgt) { when("fr_fr") { print $day" ; } when("it_it") { print $day" ; } default { print $day" ; } }

    If you want "Aujourd'hui est lundi" or "Oggi lunedi", you need to substitute those in the line for each language.
