Download favicon and convert to base64 HTML link data tag

[usemodperl]

One-liner fetches favicon from the network, converts it to base64, and prints an HTML link tag with favicon data URL. Use with discretion, favicons may be legally possessed. It's great fun to jazz local scripts and documents.

Single line data and output:

perl -MHTTP::Tiny -MMIME::Base64 -e 'print qq~<link href="data:image/x
+-icon;base64,~, encode_base64(HTTP::Tiny->new->get($ARGV[0])->{conten
+t},""), qq~" rel="icon" type="image/x-icon">~||die"something went wro
+ng"' https://perlmonks.org/favicon.ico

Multi-line data and output:

perl -MHTTP::Tiny -MMIME::Base64 -e 'print qq~<link href="data:image/x
+-icon;base64,\n~, encode_base64(HTTP::Tiny->new->get($ARGV[0])->{cont
+ent},"\n"), qq~"  rel="icon" type="image/x-icon">\n~||die"something w
+ent wrong"' https://www.perl.com/favicon.ico

Single line data and output as a script:

#!/usr/bin/perl

use strict;
use warnings;
use HTTP::Tiny;
use MIME::Base64;

push @ARGV, "https://perlmonks.org/favicon.ico" unless @ARGV;

print qq~<link href="data:image/x-icon;base64,~, 

encode_base64(HTTP::Tiny->new->get($ARGV[0])->{content},""), 

qq~" rel="icon" type="image/x-icon">~ || die "something went wrong";
