barewor...ehandles(3)

✨ NAME ✨

bareword::filehandles — disables bareword filehandles. That’s the whole assignment, bestie. 💅

🎀 VERSION 🎀

version 0.007

🦋 SYNOPSIS 🦋

Okay so you drop this into your code and the bareword-filehandle vibe check begins:

no bareword::filehandles;

open FH, $file            # dies
open my $fh, $file;       # doesn't die

print FH $string          # dies
print STDERR $string      # doesn't die

💖 DESCRIPTION 💖

Real talk: this module lexically disables the use of bareword filehandles with builtin functions. The only exceptions — the special builtin filehandles that are still invited to the group chat — are STDIN, STDOUT, STDERR, ARGV, ARGVOUT and DATA. Iconic behavior, no cap. ✨

🌈 METHODS 🌈

🧚 unimport

unimport disables bareword filehandles for the remainder of the scope being compiled. It’s giving “turn the bareword filehandle switch off,” fr fr. 🫶

🧚 import

import enables bareword filehandles for the remainder of the scope being compiled. Yep, it’s the enable side. Slay. 💖

💀 LIMITATIONS 💀

Okay, tiny caveat, don’t come for me: Filetest operators (-X) can not be checked on Perl versions before 5.32, because hooking the op check function for these breaks stacked tests, e.g. -f -w -x $file. That’s the limitation, periodt. 😭
