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).

Deserializes a YAML document.

Same as YAML.parse.

Deserializes multiple YAML documents.

Same as YAML.parse_all.

If node parses to a null value, returns nil, otherwise invokes the given block.

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.

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

require "yaml"

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

Parses a scalar value from the given node.

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

require "yaml"

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