-/*
- * Introduction
- * ************
- *
- * The following notes assume that you are familiar with the YAML specification
- * (http://yaml.org/spec/cvs/current.html). We mostly follow it, although in
- * some cases we are less restrictive that it requires.
- *
- * The process of transforming a YAML stream into a sequence of events is
- * divided on two steps: Scanning and Parsing.
- *
- * The Scanner transforms the input stream into a sequence of tokens, while the
- * parser transform the sequence of tokens produced by the Scanner into a
- * sequence of parsing events.
- *
- * The Scanner is rather clever and complicated. The Parser, on the contrary,
- * is a straightforward implementation of a recursive-descendant parser (or,
- * LL(1) parser, as it is usually called).
- *
- * Actually there are two issues of Scanning that might be called "clever", the
- * rest is quite straightforward. The issues are "block collection start" and
- * "simple keys". Both issues are explained below in details.
- *
- * Here the Scanning step is explained and implemented. We start with the list
- * of all the tokens produced by the Scanner together with short descriptions.
- *
- * Now, tokens:
- *
- * STREAM-START(encoding) # The stream start.
- * STREAM-END # The stream end.
- * VERSION-DIRECTIVE(major,minor) # The '%YAML' directive.
- * TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive.
- * DOCUMENT-START # '---'
- * DOCUMENT-END # '...'
- * BLOCK-SEQUENCE-START # Indentation increase denoting a block
- * BLOCK-MAPPING-START # sequence or a block mapping.
- * BLOCK-END # Indentation decrease.
- * FLOW-SEQUENCE-START # '['
- * FLOW-SEQUENCE-END # ']'
- * FLOW-MAPPING-START # '{'
- * FLOW-MAPPING-END # '}'
- * BLOCK-ENTRY # '-'
- * FLOW-ENTRY # ','
- * KEY # '?' or nothing (simple keys).
- * VALUE # ':'
- * ALIAS(anchor) # '*anchor'
- * ANCHOR(anchor) # '&anchor'
- * TAG(handle,suffix) # '!handle!suffix'
- * SCALAR(value,style) # A scalar.
- *
- * The following two tokens are "virtual" tokens denoting the beginning and the
- * end of the stream:
- *
- * STREAM-START(encoding)
- * STREAM-END
- *
- * We pass the information about the input stream encoding with the
- * STREAM-START token.
- *
- * The next two tokens are responsible for tags:
- *
- * VERSION-DIRECTIVE(major,minor)
- * TAG-DIRECTIVE(handle,prefix)
- *
- * Example:
- *
- * %YAML 1.1
- * %TAG ! !foo
- * %TAG !yaml! tag:yaml.org,2002:
- * ---
- *
- * The corresponding sequence of tokens:
- *
- * STREAM-START(utf-8)
- * VERSION-DIRECTIVE(1,1)
- * TAG-DIRECTIVE("!","!foo")
- * TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
- * DOCUMENT-START
- * STREAM-END
- *
- * Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
- * line.
- *
- * The document start and end indicators are represented by:
- *
- * DOCUMENT-START
- * DOCUMENT-END
- *
- * Note that if a YAML stream contains an implicit document (without '---'
- * and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
- * produced.
- *
- * In the following examples, we present whole documents together with the
- * produced tokens.
- *
- * 1. An implicit document:
- *
- * 'a scalar'
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * SCALAR("a scalar",single-quoted)
- * STREAM-END
- *
- * 2. An explicit document:
- *
- * ---
- * 'a scalar'
- * ...
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * DOCUMENT-START
- * SCALAR("a scalar",single-quoted)
- * DOCUMENT-END
- * STREAM-END
- *
- * 3. Several documents in a stream:
- *
- * 'a scalar'
- * ---
- * 'another scalar'
- * ---
- * 'yet another scalar'
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * SCALAR("a scalar",single-quoted)
- * DOCUMENT-START
- * SCALAR("another scalar",single-quoted)
- * DOCUMENT-START
- * SCALAR("yet another scalar",single-quoted)
- * STREAM-END
- *
- * We have already introduced the SCALAR token above. The following tokens are
- * used to describe aliases, anchors, tag, and scalars:
- *
- * ALIAS(anchor)
- * ANCHOR(anchor)
- * TAG(handle,suffix)
- * SCALAR(value,style)
- *
- * The following series of examples illustrate the usage of these tokens:
- *
- * 1. A recursive sequence:
- *
- * &A [ *A ]
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * ANCHOR("A")
- * FLOW-SEQUENCE-START
- * ALIAS("A")
- * FLOW-SEQUENCE-END
- * STREAM-END
- *
- * 2. A tagged scalar:
- *
- * !!float "3.14" # A good approximation.
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * TAG("!!","float")
- * SCALAR("3.14",double-quoted)
- * STREAM-END
- *
- * 3. Various scalar styles:
- *
- * --- # Implicit empty plain scalars do not produce tokens.
- * --- a plain scalar
- * --- 'a single-quoted scalar'
- * --- "a double-quoted scalar"
- * --- |-
- * a literal scalar
- * --- >-
- * a folded
- * scalar
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * DOCUMENT-START
- * DOCUMENT-START
- * SCALAR("a plain scalar",plain)
- * DOCUMENT-START
- * SCALAR("a single-quoted scalar",single-quoted)
- * DOCUMENT-START
- * SCALAR("a double-quoted scalar",double-quoted)
- * DOCUMENT-START
- * SCALAR("a literal scalar",literal)
- * DOCUMENT-START
- * SCALAR("a folded scalar",folded)
- * STREAM-END
- *
- * Now it's time to review collection-related tokens. We will start with
- * flow collections:
- *
- * FLOW-SEQUENCE-START
- * FLOW-SEQUENCE-END
- * FLOW-MAPPING-START
- * FLOW-MAPPING-END
- * FLOW-ENTRY
- * KEY
- * VALUE
- *
- * The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
- * FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
- * correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the
- * indicators '?' and ':', which are used for denoting mapping keys and values,
- * are represented by the KEY and VALUE tokens.
- *
- * The following examples show flow collections:
- *
- * 1. A flow sequence:
- *
- * [item 1, item 2, item 3]
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * FLOW-SEQUENCE-START
- * SCALAR("item 1",plain)
- * FLOW-ENTRY
- * SCALAR("item 2",plain)
- * FLOW-ENTRY
- * SCALAR("item 3",plain)
- * FLOW-SEQUENCE-END
- * STREAM-END
- *
- * 2. A flow mapping:
- *
- * {
- * a simple key: a value, # Note that the KEY token is produced.
- * ? a complex key: another value,
- * }
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * FLOW-MAPPING-START
- * KEY
- * SCALAR("a simple key",plain)
- * VALUE
- * SCALAR("a value",plain)
- * FLOW-ENTRY
- * KEY
- * SCALAR("a complex key",plain)
- * VALUE
- * SCALAR("another value",plain)
- * FLOW-ENTRY
- * FLOW-MAPPING-END
- * STREAM-END
- *
- * A simple key is a key which is not denoted by the '?' indicator. Note that
- * the Scanner still produce the KEY token whenever it encounters a simple key.
- *
- * For scanning block collections, the following tokens are used (note that we
- * repeat KEY and VALUE here):
- *
- * BLOCK-SEQUENCE-START
- * BLOCK-MAPPING-START
- * BLOCK-END
- * BLOCK-ENTRY
- * KEY
- * VALUE
- *
- * The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
- * increase that precedes a block collection (cf. the INDENT token in Python).
- * The token BLOCK-END denote indentation decrease that ends a block collection
- * (cf. the DEDENT token in Python). However YAML has some syntax pecularities
- * that makes detections of these tokens more complex.
- *
- * The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
- * '-', '?', and ':' correspondingly.
- *
- * The following examples show how the tokens BLOCK-SEQUENCE-START,
- * BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
- *
- * 1. Block sequences:
- *
- * - item 1
- * - item 2
- * -
- * - item 3.1
- * - item 3.2
- * -
- * key 1: value 1
- * key 2: value 2
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * BLOCK-SEQUENCE-START
- * BLOCK-ENTRY
- * SCALAR("item 1",plain)
- * BLOCK-ENTRY
- * SCALAR("item 2",plain)
- * BLOCK-ENTRY
- * BLOCK-SEQUENCE-START
- * BLOCK-ENTRY
- * SCALAR("item 3.1",plain)
- * BLOCK-ENTRY
- * SCALAR("item 3.2",plain)
- * BLOCK-END
- * BLOCK-ENTRY
- * BLOCK-MAPPING-START
- * KEY
- * SCALAR("key 1",plain)
- * VALUE
- * SCALAR("value 1",plain)
- * KEY
- * SCALAR("key 2",plain)
- * VALUE
- * SCALAR("value 2",plain)
- * BLOCK-END
- * BLOCK-END
- * STREAM-END
- *
- * 2. Block mappings:
- *
- * a simple key: a value # The KEY token is produced here.
- * ? a complex key
- * : another value
- * a mapping:
- * key 1: value 1
- * key 2: value 2
- * a sequence:
- * - item 1
- * - item 2
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * BLOCK-MAPPING-START
- * KEY
- * SCALAR("a simple key",plain)
- * VALUE
- * SCALAR("a value",plain)
- * KEY
- * SCALAR("a complex key",plain)
- * VALUE
- * SCALAR("another value",plain)
- * KEY
- * SCALAR("a mapping",plain)
- * BLOCK-MAPPING-START
- * KEY
- * SCALAR("key 1",plain)
- * VALUE
- * SCALAR("value 1",plain)
- * KEY
- * SCALAR("key 2",plain)
- * VALUE
- * SCALAR("value 2",plain)
- * BLOCK-END
- * KEY
- * SCALAR("a sequence",plain)
- * VALUE
- * BLOCK-SEQUENCE-START
- * BLOCK-ENTRY
- * SCALAR("item 1",plain)
- * BLOCK-ENTRY
- * SCALAR("item 2",plain)
- * BLOCK-END
- * BLOCK-END
- * STREAM-END
- *
- * YAML does not always require to start a new block collection from a new
- * line. If the current line contains only '-', '?', and ':' indicators, a new
- * block collection may start at the current line. The following examples
- * illustrate this case:
- *
- * 1. Collections in a sequence:
- *
- * - - item 1
- * - item 2
- * - key 1: value 1
- * key 2: value 2
- * - ? complex key
- * : complex value
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * BLOCK-SEQUENCE-START
- * BLOCK-ENTRY
- * BLOCK-SEQUENCE-START
- * BLOCK-ENTRY
- * SCALAR("item 1",plain)
- * BLOCK-ENTRY
- * SCALAR("item 2",plain)
- * BLOCK-END
- * BLOCK-ENTRY
- * BLOCK-MAPPING-START
- * KEY
- * SCALAR("key 1",plain)
- * VALUE
- * SCALAR("value 1",plain)
- * KEY
- * SCALAR("key 2",plain)
- * VALUE
- * SCALAR("value 2",plain)
- * BLOCK-END
- * BLOCK-ENTRY
- * BLOCK-MAPPING-START
- * KEY
- * SCALAR("complex key")
- * VALUE
- * SCALAR("complex value")
- * BLOCK-END
- * BLOCK-END
- * STREAM-END
- *
- * 2. Collections in a mapping:
- *
- * ? a sequence
- * : - item 1
- * - item 2
- * ? a mapping
- * : key 1: value 1
- * key 2: value 2
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * BLOCK-MAPPING-START
- * KEY
- * SCALAR("a sequence",plain)
- * VALUE
- * BLOCK-SEQUENCE-START
- * BLOCK-ENTRY
- * SCALAR("item 1",plain)
- * BLOCK-ENTRY
- * SCALAR("item 2",plain)
- * BLOCK-END
- * KEY
- * SCALAR("a mapping",plain)
- * VALUE
- * BLOCK-MAPPING-START
- * KEY
- * SCALAR("key 1",plain)
- * VALUE
- * SCALAR("value 1",plain)
- * KEY
- * SCALAR("key 2",plain)
- * VALUE
- * SCALAR("value 2",plain)
- * BLOCK-END
- * BLOCK-END
- * STREAM-END
- *
- * YAML also permits non-indented sequences if they are included into a block
- * mapping. In this case, the token BLOCK-SEQUENCE-START is not produced:
- *
- * key:
- * - item 1 # BLOCK-SEQUENCE-START is NOT produced here.
- * - item 2
- *
- * Tokens:
- *
- * STREAM-START(utf-8)
- * BLOCK-MAPPING-START
- * KEY
- * SCALAR("key",plain)
- * VALUE
- * BLOCK-ENTRY
- * SCALAR("item 1",plain)
- * BLOCK-ENTRY
- * SCALAR("item 2",plain)
- * BLOCK-END
