Text::Diff::Config(3)

💅 Text::Diff::Config(3) — like, the manual page, bestie

okay so real talk, this is Text::Diff::Config(3) from the User Contributed Perl Documentation and it is genuinely one of the shortest manpages you will ever meet. it's a whole module whose entire personality is one boolean. and honestly? icon behaviour. 🎀

---

✨ NAME ✨

Text::Diff::Config — global configuration for Text::Diff (as a separate module).

yes bestie, as a separate module. that's the whole bit. it's the config shelf for Text::Diff, living on its own so it can vibe independently. 🦋

---

🌸 SYNOPSIS 🌸

use Text::Diff::Config;

$Text::Diff::Config::Output_Unicode = 1;

that's it. that's the synopsis. two lines. load the module, flip the flag to 1, and you are done — main character energy, minimal effort. 💅

---

🧚 DESCRIPTION 🧚

so here's the tea: this module configures Text::Diff and its related modules. 🫶

right now — and "currently" is doing a lot of work in that sentence — it contains only one global variable:

• $Text::Diff::Config::Output_Unicode — a boolean flag. if it's set, unicode characters get output as themselves, without escaping them first as " \x{HHHH} ". so instead of a bunch of sad little escape sequences, you get the actual pretty characters. slay. ✨

it gets initialized to the value of $ENV{DIFF_OUTPUT_UNICODE} — so yes, you can absolutely set that env var and have it just work, iykyk. 💜

but also? you can set it to a different value at run-time, no problem. including using local. 🩷

lowkey the most important part: local. go off with your dynamically scoped little flag, bestie, it's valid and it's beautiful.

🦋 a tiny meta note 🦋

the source page literally runs NAME → SYNOPSIS → DESCRIPTION → AUTHOR → LICENSE and then does the entire thing again from the top, word for word. not me noticing that 💀 — but we're not making you read the whole license twice, bestie. once is enough. it's giving copy-paste, and honestly? relatable.
