def self.each(node : YAML::Nodes::Mapping, &block) #

Invokes the block for each of the given nodes keys and values, resolving merge keys (<<) when found (keys and values of the resolved merge mappings are yielded, recursively).

def self.parse_scalar(pull_parser : YAML::PullParser) : Type #

Assuming the pull_parser is positioned in a scalar, parses it according to the core schema, taking the scalar's style and tag into account, then advances the pull parser.

def self.parse_scalar(node : YAML::Nodes::Scalar) : Type #

Parses a scalar value from the given node.

def self.parse_scalar(string : String) : Type #

Parses a string according to the core schema, assuming the string had a plain style.

YAML::Schema::Core.parse_scalar("hello") # => "hello"
YAML::Schema::Core.parse_scalar("1.2")   # => 1.2
YAML::Schema::Core.parse_scalar("false") # => false

[View source]
def self.reserved_string?(string) : Bool #

Returns whether a string is reserved and must non be output with a plain style, according to the core schema.

YAML::Schema::Core.reserved_string?("hello") # => false
YAML::Schema::Core.reserved_string?("1.2")   # => true
