🎀 Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters(3pm) 🎀

So this is a page from the User Contributed Perl Documentation (perl v5.42.0, dated 2024-10-23, bestie, write it down), and it's about a Perl::Critic policy with the most extra name ever: Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters. Basically: write "\N{DELETE}" instead of "\x7F", etc. 💅

---

✨ NAME ✨

Perl::Critic::Policy::ValuesAndExpressions::ProhibitEscapedCharacters — literally the policy that tells you to write "\N{DELETE}" instead of "\x7F", etc. 🦋

🌸 AFFILIATION 🌸

Okay so this Policy is part of the core Perl::Critic distribution. It comes with the package, no extra install drama. 👑

💖 DESCRIPTION 💖

Escaped numeric values are hard to read and debug. Like, genuinely. Not me squinting at \x7F trying to remember what that even is 😭. Instead, use named values. The syntax is less compact, but dramatically more readable. It's giving "a little more typing, a whole lot more brain cells saved".

$str = "\x7F\x06\x22Z";                         # not ok

use charnames ':full';
$str = "\N{DELETE}\N{ACKNOWLEDGE}\N{CANCEL}Z";  # ok

See? The second one actually says what it means. Main character energy. 🔥

🧚 CONFIGURATION 🧚

This Policy is not configurable except for the standard options. That's it, that's the whole vibe check. No knobs, no dials, no [ValuesAndExpressions::ProhibitEscapedCharacters] customization arc for you. 🫶
