NAME

Subsets::IO - Subsets for various types of IO::Path instances

SYNOPSIS

use Subsets::IO;

say "Our script is writable and readable"
    if $?FILE.IO ~~ IO::Path::frw;
use Subsets::IO;

sub make-conf($conf where IO::Path::dw | IO::Path::fw) {
    say "$conf is either a writable directory or a writable file";
}

sub make-conf-file(IO::Path::E $conf) {
    say "$conf is a non-existent path";
}
make-conf-file $?FILE.IO;
# Path must NOT exist Got /home/zoffix/CPANPRC/Subsets-IO/foo.p6
# Constraint type check failed in binding to parameter '$conf';
#   expected IO::Path::E but got IO::Path (IO::Path.new("/home/z...)

DESCRIPTION

The module provides subsets of IO::Path:D that additionally perform file tests and either uses the new will complain (since Rakudo 2022.04) feature, or uses Subset::Helper to display useful error messages on typecheck failures.
