YAML is a "human-readable data serialization format", according to Wikipedia. Apparently it's terribly flexible and powerful. But I just want to make a simple configuration file to use with a Perl script. I worked out how to do this with help from Stackoverflow (I love Stackoverflow). Super-simple example:
test.yaml:
test.pl:
You can also go backwards: starting from the Perl code version of the configuration data you want, you can generate the YAML file:
make_yaml.pl
Hmmm, funny how the Stackoverflow people assume I'm a "he" though.
test.yaml:
---
image_width: 1000
show_values: 0
test.pl:
#!/usr/bin/perl
use strict;
use warnings;
use 5.010;
use YAML qw(LoadFile);
my $settings = LoadFile('test.yaml');
say "The image width is ", $settings->{image_width};
You can also go backwards: starting from the Perl code version of the configuration data you want, you can generate the YAML file:
make_yaml.pl
use strict;
use warnings;
use YAML;
my %settings = (
foo => 1,
bar => [qw/one two three/],
);
print Dump(\%settings);
