Perl::...ckGrep(3pm)

💖 NAME 💖

okay bestie, welcome to the Perl::...ckGrep(3pm) page 💅 this is all about Perl::Critic::Policy::BuiltinFunctions::RequireBlockGrep — the policy that wants you to write grep { /$pattern/ } @list instead of grep /$pattern/, @list. That's it, that's the vibe. ✨

🏠 AFFILIATION 🏠

This Policy is part of the core Perl::Critic distribution. No extra drama. 🫶

🌸 DESCRIPTION 🌸

So the tea is: the expression forms of grep and map are awkward and hard to read. Use the block forms instead, periodt. 💅

@matches = grep  /pattern/,    @list;        #not ok
@matches = grep { /pattern/ }  @list;        #ok

@mapped = map  transform($_),    @list;      #not ok
@mapped = map { transform($_) }  @list;      #ok

⚙️ CONFIGURATION ⚙️

This Policy is not configurable except for the standard options. That's the whole config chapter, bestie — no secret knobs. 🙈
