NAME

silently - prevent any output from a block

SYNOPSIS

use silently;

DESCRIPTION

silently is module that exports a single sub called silently that takes a block to execute. Inside that block, all textual output to $*OUT and $*ERR is prevented from actually being sent to STDOUT and STDERR.

Note that if you're only interested in surpressing output from warnings, you should use the quietly statement prefix.

SUBROUTINES

silently

silently { say "hello world" }  # no output

my $captured = silently { note "tis wrong" }
if $captured.err -> $error {
  say "something went wrong: $error";
}

The silently subroutine takes a block as a parameter, and runs that block catching all output to $*OUT and $*ERR.

If the output is actually needed for inspection: the subroutine returns an object that provides two methods: out and err, giving the captured output to $*OUT and $*ERR respectively.
