A YAML Loader and Dumper
Currently this depends on LibYAML.pm6
You can install this YAML module from source like this:
$ zef install https://github.com/yaml/yaml-perl6.git
# or
$ git clone https://github.com/yaml/yaml-perl6.git
$ cd yaml-perl6
$ zef install .
The toplevel API is the first thing we want to get stable. The layer under that, the Loader/Dumper/Reader/Writer/Parser/Emitter will change, so it's not recommended to use that and think it will always work. Make sure to update LibYAML also when updating this module.
# current usage
use YAML;
my $yaml = q:to/./
---
integer: 23
map:
a: true
b: false
sequence:
- x
- y
- z
...
---
This is: document no. 2
...
.
# get back single document
# note that currently, this will parse the complete string instead
# of stopping after the first document
my $doc = yaml.load($yaml);
my %hash = yaml.load($yaml);
# load all documents
my @docs = yaml.all.load($yaml);
my $docs = yaml.all.load($yaml);
# dump data to YAML
my $yaml = yaml.dump(%data1, @data2, ...);
my @docs = (%data1, @data2);
my $yaml = yaml.dump(@docs);
- Load and Dump strings, numbers, booleans, arrays, hashes, (objects)
- Load and Dump Aliases/Anchors, including cyclic structures
- Tags
- Files and Filehandles
- Error messages
- Allow other parsers/emitters as a backend
- Other low level API stuff
YAMLish is a pure-perl6 module for
YAML that doesn't rely on an external library like YAML currently does.
