Catman...EPHSEQ(3pm)

💖 Catmandu::Exporter::MARC::ALEPHSEQ 💖

okay bestie so this is a page from the User Contributed Perl Documentation (perl v5.38.2, dated 2024-08-03, keep that in your notes 📝) and it's all about the Catmandu::Exporter::MARC::ALEPHSEQ module — an exporter that takes MARC records and spits them out in Ex Libris' Aleph sequential format. that's it. that's the whole vibe. 🦋

---

✨ NAME ✨

Catmandu::Exporter::MARC::ALEPHSEQ — Exporter for MARC records to Ex Libris' Aleph sequential. no cap, that's literally what it does 💅

---

🌸 SYNOPSIS 🌸

okay so first, from the command line, look how easy this is:

# From the command line
$ catmandu convert MARC to MARC --type ALEPHSEQ < /foo/data.mrc

and from Perl, if that's your thing (it is, we're built different 🫶):

# From Perl
use Catmandu;

my $importer = Catmandu->importer('MARC', file => "/foo/bar.mrc" , type => 'ISO');
my $exporter = Catmandu->exporter('MARC', file => "marc.txt", type => 'ALEPHSEQ' );

$exporter->add($importer);
$exporter->commit;

see? importer in, exporter out, add, commit, done. the way that just works 😭✨

🎀 CONFIGURATION 🎀

these are the lil knobs you can turn, and every single one of them matters so pay attention bestie:

• file — Write output to a local file given by its path or file handle. Alternatively a scalar reference can be passed to write to a string and a code reference can be used to write to a callback function. so like, path? handle? scalar ref for string life? coderef for callback era? your choice, queen 👑
• fh — Write the output to an IO::Handle. If not specified, Catmandu::Util::io is used to create the output handle from the file argument or by using STDOUT. so if you don't hand it a handle, it'll build one from file, and if there's no file, it's STDOUT time 🌈
• fix — An ARRAY of one or more fixes or file scripts to be applied to exported items. this is where you do your little transformations before things go out the door, slay 💅
• encoding — Binmode of the output stream fh. Set to ":utf8" by default. the default is literally ":utf8", we love an encoding that's already handled 🥰
• default_fmt — Set the value of the default FMT field when none is given. Set to "BK" by default. so no FMT? it's "BK". iconic behaviour, honestly 👑
