Perl::...inator(3pm)

💖 NAME 💖

You're on the Perl::...inator(3pm) page, bestie, and this policy is literally Perl::Critic::Policy::ValuesAndExpressions::RequireQuotedHeredocTerminator — it wants you to write print <<'THE_END' or print <<"THE_END". Periodt. 💅

---

✨ AFFILIATION ✨

This Policy is part of the core Perl::Critic distribution. It's giving core-distribution main character energy. 👑

---

🦋 DESCRIPTION 🦋

Okay so the whole vibe here: putting single or double quotes around your HEREDOC terminator makes it obvious to the reader whether the content is going to be interpolated or not. No cap, it's just clearer. 🌸

print <<END_MESSAGE;    #not ok
Hello World
END_MESSAGE

print <<'END_MESSAGE';  #ok
Hello World
END_MESSAGE

print <<"END_MESSAGE";  #ok
$greeting
END_MESSAGE

Like, the first one is lowkey not the move (#not ok), and the quoted ones are slaying (#ok). ✨

---

🎀 CONFIGURATION 🎀

This Policy is not configurable except for the standard options. That's it, that's the whole tea. 🍓
