JSON::Pointefr

A JSON Pointer implementation in Raku.

Synopsis

use JSON::Pointer;

# An example document to resolve pointers in
my $sample-json = {
    foo => [
        {
            bar => 42
        },
        {
            'weird~odd/name' => 101
        }
    ]
}

# Simple usage
my $p = JSON::Pointer.parse('/foo/0/bar');
say $p.tokens; # [foo 0 bar]
say $p.resolve($sample-json); # 42

# ~ and / are escaped as ~0 and ~1
my $p2 = JSON::Pointer.parse('/foo/1/weird~0odd~1name');
say $p2.tokens; # [foo 1 weird~odd/name]
say $p2.resolve($sample-json); # 101

# A Failure is returned upon resolution failure
my $p3 = JSON::Pointer.parse('/foo/2/missing');
without $p3.resolve($sample-json) {
    say "Could not resolve";
}

# Construct a JSON pointer
my $p4 = JSON::Pointer.new('foo', 0, 'weird~odd/name');
say ~$p4; # /foo/0/weird~0odd~1name
