Data::...Reader(3pm)

✨ NAME ✨

Data::YAML::Reader — bestie, this parses YAML that was made by Data::YAML::Writer 💖

(also it's a Data::...Reader(3pm) situation, from User Contributed Perl Documentation, just so you know what you're looking at 🫶)

🌸 VERSION 🌸

This doc describes Data::YAML::Reader version 0.0.7 ✨

🎀 SYNOPSIS 🎀

use Data::YAML::Reader;

my $yr = Data::YAML::Reader->new;

# Read from an array...
my $from_array = $yr->read( \@some_array );

# ...an open file handle...
my $from_handle = $yr->read( $some_file );

# ...a string containing YAML...
my $from_string = $yr->read( $some_string );

# ...or a closure
my $from_code = $yr->read( sub { return get_next_line() } );

okay so literally four different ways to feed it, pick your fighter 💅

🦋 DESCRIPTION 🦋

In the spirit of YAML::Tiny, this is a lightweight, dependency-free YAML reader. No extra CPAN boxes to install, she just works ✨

But here's the tea: while YAML::Tiny is designed principally for working with configuration files, Data::YAML concentrates on the transparent round-tripping of YAML serialized Perl data structures. Different goals, different girlies 💖

The syntax accepted by Data::YAML::Reader is a subset of YAML. Specifically? It's the same subset of YAML that Data::YAML::Writer produces. Like, they're a matched set, besties fr fr. See Data::YAML for more information 👑

🌈 INTERFACE 🌈

💜 new

Creates and returns an empty Data::YAML::Reader object. No options may be passed. That's it, that's the whole vibe — no arguments, no config, no drama 🙈

💜 read( $source )

Read YAML and return the data structure it represents. The YAML data may be supplied by a:

• scalar string containing YAML source
• the handle of an open file
• a reference to an array of lines
• a code reference

In the case of a code reference, a subroutine (most likely a closure) that returns successive lines of YAML must be supplied. Lines should have no trailing newline. When the YAML is exhausted the subroutine must return undef. That last bit is not optional, bestie, it's how she knows you're done 🫶

Returns the data structure (specifically either a scalar, hash ref or array ref) that results from decoding the YAML. So yeah — scalar, hash ref, or array ref, those are your three options 👑

💜 get_raw

Return the raw YAML source from the most recent read. Like a lil peek at the receipt from your last order 🧾✨

💀 BUGS AND LIMITATIONS 💀

No bugs have been reported. (iconic behaviour, honestly)
