Returns the block length of the digest algorithm, i.e. the length in bytes of an individual block. Most modern algorithms partition a message to be digested into a sequence of fix-sized blocks that are processed consecutively.

Example

digest = OpenSSL::Digest.new('SHA1')
puts digest.block_length # => 64

Called when the document starts with the declared version, tag_directives, if the document is implicit.

version will be an array of integers indicating the YAML version being dealt with, tag_directives is a list of tuples indicating the prefix and suffix of each tag, and implicit is a boolean indicating whether the document is started implicitly.

Example

Given the following YAML:

%YAML 1.1
%TAG ! tag:tenderlovemaking.com,2009:
--- !squee

The parameters for start_document must be this:

version         # => [1, 1]
tag_directives  # => [["!", "tag:tenderlovemaking.com,2009:"]]
implicit        # => false

Called with the document ends. implicit is a boolean value indicating whether or not the document has an implicit ending.

Example

Given the following YAML:

---
  hello world

implicit will be true. Given this YAML:

---
  hello world
...

implicit will be false.

Called before each event with line/column information.

Handles start_document events with version, tag_directives, and implicit styling.

See Psych::Handler#start_document

Handles end_document events with version, tag_directives, and implicit styling.

See Psych::Handler#start_document

Start a document emission with YAML version, tags, and an implicit start.

See Psych::Handler#start_document

End a document emission with an implicit ending.

See Psych::Handler#end_document

This method is called when a parse error is found.

ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling token_to_str.

ERROR_VALUE is a value of error token.

value_stack is a stack of symbol values. DO NOT MODIFY this object.

This method raises ParseError by default.

If this method returns, parsers enter “error recovering mode”.

Replace %w+% into the environment value of what is contained between the %‘s This method is used for REG_EXPAND_SZ.
