I agree. The dependency that "dangling_symlinks" has on "follow => 1" is
not reflected in the man page.
"dangling_symlinks"
If true and a code reference, will be called with the symbolic
link
name and the directory it lives in as arguments. Otherwise, if
true
and warnings are on, warning "symbolic_link_name is a dangling
symbolic
link\n" will be issued. If false, the dangling symbolic link will
be
silently ignored.
Code such as this would not work:
find({
wanted => sub { print $File::Find::name . "\n"; },
dangling_symlinks => sub { print "dangling: " . $File::Find::name .
"\n"; },
}, qw(dir_to_search));
but this would:
find({
wanted => sub { print $File::Find::name . "\n"; },
dangling_symlinks => sub { print "dangling: " . $File::Find::name .
"\n"; },
follow => 1,
}, qw(dir_to_search));
Perhaps the documentation could be changed to something like:
"dangling_symlinks"
If true and a code reference and "follow => 1", will be called
with the symbolic link
name and the directory it lives in as arguments. Otherwise, if
true
and warnings are on, warning "symbolic_link_name is a dangling
symbolic
link\n" will be issued. If false, the dangling symbolic link will
be
silently ignored.
