DBM_Fil...ompress(3pm)

💅 DBM_Filter::compress — the tea ☕

ok so bestie, real talk: this is the DBM_Filter::compress page from the Perl Programmers Reference Guide, and honestly? it's a tiny little page but it does exactly one thing and it does it iconically.

---

✨ NAME ✨

DBM_Filter::compress — it's a filter for DBM_Filter, periodt. that's the whole vibe.

---

🎀 SYNOPSIS 🎀

like, copy this exactly, no cap:

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

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

yes bestie, SDBM_File or DB_File, GDBM_File, NDBM_File, ODBM_File — pick your fighter 🥊

---

🦋 DESCRIPTION 🦋

okay so here's the whole deal, and it's lowkey elegant:

this DBM filter compresses all your data before it gets written to the database, and then it uncompresses it on reading. it's giving "zip it up, unzip it later" ✨ main character energy for your hash values.

⚠️ and listen — a fatal error will be thrown if the Compress::Zlib module is not available. not a vibe check gone wrong, an actual fatal error. so make sure Compress::Zlib is installed before you come for this filter, k? 💀

🌸 and that's the whole page, bestie 🌸

cute little sign-off: this page came with perl v5.42.3, dated 2026-11-03, and yes the header/footer thing is literally just DBM_Fil...ompress(3pm) truncated because terminals are dramatic. now go compress something 💖🎀
