... or how to find X<>-refs in Pod and search them in pager
Problem
Did you ever try to find the documentation of the ".." (flip-flop) operator?
typing perldoc -f .. doesn't help ...
But perldocs have tags like X<..> indicating the right documentation, only the formatters are missing.$ perldoc -f .. No documentation for perl function `..' found

Approach
Usage
Prove of concept
Just a hack ("release often" dogma)
Tested for linux.
file "pdoc"
#!/usr/bin/perl use strict; # use Data::Dump; my $poddir = `perldoc -l perltoc`; chomp $poddir; $poddir =~ s/perltoc/*/; my $pattern = $ARGV[0]; my @pods= grep {! /perltoc/} `grep -l -F 'X<$pattern>' $poddir`; chomp @pods; # dd @pods; for my $infile (@pods) { open my $in, "<", $infile; my $outfile = "/tmp/". (split "/",$infile)[-1]; open my $out,">", $outfile; local $/="\n\n"; my $marker = ">>> X<$pattern> <<<"; #"MARK"; while (my $para = <$in>){ print $out "\nC<<<< $marker >>>>\n\n" if $para =~ /X<\Q$pattern\E>/; print $out $para; } close $out; my $ret = `pod2man $outfile |nroff -man > /tmp/tmp.man`; print system("less -p \"$marker\" /tmp/tmp.man") }
