✨ NAME ✨

okay bestie, meet Regexp::Common::URI::fax — a User Contributed Perl Documentation page (section 3) that literally returns a pattern for fax URIs. That's the name, that's the mission, slay. 💅

🌸 SYNOPSIS 🌸

Here's the exact group-chat demo, bestie — read it, run it, it prints when your line contains a fax URI. 🦋

use Regexp::Common qw /URI/;

while (<>) {
    /$RE{URI}{fax}/       and  print "Contains a fax URI.\n";
}

🦋 DESCRIPTION 🦋

🎀 $RE{URI}{fax} 🎀

Returns a pattern that matches fax URIs, as defined by RFC 2806. Under "{-keep}", the following are returned:

  • $1 — the complete URI. 💖
  • $2 — the scheme. ✨
  • $3 — the phone number, including any possible add-ons like ISDN subaddress, a post dial part, area specifier, service provider, etc. 📞

🦋 "$RE{URI}{fax}{nofuture}" 🦋

As above (including what's returned by "{-keep}"), with the exception that future extensions are not allowed. So nofuture is the no surprise future stuff version. 🚫🔮

Without allowing those future extensions, it becomes much easier to check a URI if the correct syntax for post dial, service provider, phone context, etc has been used - otherwise the regex could always classify them as a future extension. That's the lowkey important part, fr fr. 💅
