💖 DBM_Filter::compress — bestie edition 💖

okay so real talk, this is the DBM_Filter::compress page from the Perl Programmers Reference Guide. it's a lil guy. a filter. and it's about to make ur database data ✨smaller✨. let's get into it 🫶

---

🌸 NAME 🌸

DBM_Filter::compress — it's a filter for DBM_Filter, no cap

---

✨ SYNOPSIS ✨

okay so here's the vibe, copy-paste style:

use SDBM_File; # or DB_File, GDBM_File, NDBM_File, ODBM_File
use DBM_Filter ;

$db = tie %hash, ...
$db->Filter_Push('compress');

that's it. that's the whole ritual. 💅

---

🦋 DESCRIPTION 🦋

so basically this DBM filter is obsessed with squishing ur data down before it ever gets written to the database, and then it unsquishes it on the way back out when you read it. compress on write, decompress on read. it's giving zip file energy but make it a filter. 🎀

⚠️ bestie listen — if the Compress::Zlib module isn't available, this thing throws a fatal error. like, not a vibe check, an actual death. so make sure Compress::Zlib is installed before u push this filter, fr fr. 😭
