IO::CatHandle::AutoLines - Get IO::CatHandle's current handle's line number


code

=begin code :lang<raku>

use IO::CatHandle::AutoLines;

'some'   .IO.spurt: "a\nb\nc";
'files'  .IO.spurt: "d\ne\nf";
'to-read'.IO.spurt: "g\nh";

# OUTPUT:
# Meow!
# 1: a
# 2: b

# Meow!
# 1: d
# 2: e
# 3: f
# Meow!
# 1: g

# Meow!

=end code


A role that adds an <C.ln> method to the
L<C<IO::CatHandle>|https://docs.raku.org/type/IO::CatHandle> type that
will contain the current line number. Optionally, the lines counter can
be reset when next source handle get switched into.


B<Note:> only the
L<C<.lines>|https://docs.raku.org/type/IO::CatHandle#method_lines> and
L<C<.get>|https://docs.raku.org/type/IO::CatHandle#method_get> methods
are overriden to increment the line counter. Using any other methods to
read data will B<not> increment the line counter.


=begin code :lang<raku>

role IO::CatHandle::AutoLines[Bool:D :$reset = True]

=end code


Provides an C<.ln> method containing C<Int:D> of the current line number.
If C<:$reset> parameter is set to C<True> (default), then on source
handle switch, the line number will be reset back to zero.


=begin code :lang<raku>

# Reset on-switch enabled
my $cat1 = IO::CatHandle.new(…) does role IO::CatHandle::AutoLines;

# Reset on-switch disabled
my $cat2 = IO::CatHandle.new(…) does role IO::CatHandle::AutoLines[:!reset];

AutoLines

NAME

use IO::Socket::TLSViaAsync;
my $ssl = IO::Socket::TLSViaAsync.new(:host<example.com>, :port(443));
if $ssl.print("GET / HTTP/1.1\r\n\r\n") {
    say $ssl.recv;
}


This module provides an interface for TLS connections. It's a drop in
replacement of C<IO::Socket::INET>.


Technically it's a wrapper around the C<IO::Socket::Async::SSL> module. The
C<new>, C<connect> and C<listen> methods forward their named arguments to the
C<connect> and C<listen> methods in C<IO::Socket::Async::SSL> respectively.


It's not possible to initialize an instance of C<IO::Socket::TLSViaAsync> with
an C<IO::Socket::INET> object, because C<IO::Socket::TLSViaAsync> is based on
C<IO::Socket::Async::SSL> which in turn is based on C<IO::Socket::Async>, which
is incompatible with C<IO::Socket>.
