	General SQL Parser: sql engine for various databases
		After read all input sql, a source token list is generated which is the input of the yacc parser.
		Yacc parser read source token in SourceTokenList,based on the BNF of different database dialects, the parser will create a raw parse tree if no syntax error was found.
		During the translation, parser will iterate the whole raw parse tree, and OnTableToken event will be fired if a source token stands for a table is found, OnFieldToken event will be fired if a source token stands for a field is found.

	Token (parser) - Wikipedia, the free encyclopedia
		In computing, a token is a categorized block of text, usually consisting of indivisible characters known as lexemes.
		Tokens are frequently defined by regular expressions, which are understood by a lexical analyzer such as lex.
		Tokenization is the process of demarcating and possibly classifying sections of a string of input characters.

	Glossary of Parsing Terms
		The inputs are the tokens of your grammar.
		The semantic value of the token and the current state number are stacked, the parser stack index is incremented and the state number is set to a value determined by the previous state and the input token.
		The tokens identified by a parser are concrete instances of the abstract tokens in the grammar.

	Introduction to Syntax Directed Parsing
		The parser keeps track of all the dependencies in your input, and calls certain functions, reduction procedures, to deal with specific units or sequences of data as they are encountered.
		A token is not shifted into the buffer unless it "makes sense", that is, unless it is consistent with the rules of the grammar and with the input that has preceded it.
		At the same time that input tokens are removed from the input buffer, state numbers are popped from the state stack, so that when all input tokens matching the rule have been removed, the parser state has been restored to the value it had at the time the first token in the rule was seen.

	Wikinfo \| Token
		A token may also be a piece of metal or a wooden chip used as a substitute for currency.
		On railways, a token is a physical object given to a locomotive driver to authorise him to use a particular stretch of single track.
		In computing, a token is a virtual object that is passed between computers or other devices on a network to enable them to communicate.

	Application Development Trends - Parsing With JavaCC
		Most likely, you are not developing a parser for the pure joy of programming—you are developing a parsing application so that something useful may be done with the data from the input stream.
		Parsers are very complex beasts and quite difficult to implement correctly on the first pass.
		Token objects maintain their own public image attribute; however, this attribute is an immutable String object for tokens and not a StringBuffer object.

	LL(1) Parsers
		The method is called recursive descent because the parser is implemented as a set of mutually recursive parsing routines, and because it is a top-down method.
		The parser, once written, becomes the foundation of the whole compiler, and the scope analyser, type analyser, and code generator are all relatively easily integrated into the parser.
		We will assume that a Token has the representation discussed in the chapter on the scanner, that is it has a field byte token which contains the enumerated type value of the token, and int value, which contains the value of the numeral or the unique integer associated with a name.

	Module Parser
		parser sentence =:= rest ">and> repexp =:= rep = rest where rest free -- Finally, we define some useful basic parsers and derived combinators: --- The empty parser which recognizes the empty word.
		sym=:=token = tokens --- A parser (with representation) recognizing a terminal satisfying --- a given predicate.
		The presentation of this parser is the value of the expression.

	The parser generator JavaCC
		Tokens are recognized by regular expressions which are specified locally or globally within the grammar.
		Parsers can be generated so that there can be multiple instances and they can be operated in parallel.
		depends on the parser class and is the base class of the individual node classes.

	Token
		This field is used to access special tokens that occur prior to this token, but after the immediately preceding regular (non-special) token.
		If this is the last token from the input stream, or if the token manager has not read tokens beyond this one, this field is set to null.
		When there are more than one such special token, this field refers to the last of these special tokens, which in turn refers to the next previous special token through its specialToken field, and so on until the first special token (whose specialToken field is null).

	Creating a Recursive-Descent Parser
		A parser is a program that given a sentence in its language, will construct a derivation of that sentence to check it for syntactic correctness.
		Although parsers can be generated by parser generators, it is still sometimes convenient to write a parser by hand.
		An LALR(1) grammar is not appropriate for constructing a recursive descent parser.

	PHP: XML Parser Functions - Manual
		Note that the XML parser does not add or remove any whitespace, it is up to the application (you) to decide whether whitespace is significant.
		Upon creating an XML parser, a source encoding can be specified (this encoding can not be changed later in the XML parser's lifetime).
		When an XML parser is created, the target encoding is set to the same as the source encoding, but this may be changed at any point.

		part of the grammar, and the number of tokens that were read from the string.
		If a different parser or scanner is being used, the token count is needed, or a exceptions are to be handled differently, a new
		For example, in parsing a Pascal-like language with ``begin'' and ``end'' as keywords, a context sensitive scanner would only match ``end'' as the END token if the parser is in a place that will accept the END token.

	Bison 2.3
		Parser States: The parser is a finite-state-machine with stack.
		The tokens of C are identifiers, constants (numeric and string), and the various keywords, arithmetic operators and punctuation marks.
		Each of the cloned parsers eventually meets one of two possible fates: either it runs into a parsing error, in which case it simply vanishes, or it merges with another parser, because the two of them have reduced the input to an identical set of symbols.

	Parsec, a fast combinator parser
		Most parsers take their input from a lexical analyzer or scanner which filters white space and comments and returns a list tokens for the parser.
		A parser for the Henk language as descibed by Peyton Jones and Meijer (1997).
		They occur at parsers that would normally constitute lexical tokens in a traditional parser, and are sometimes seen at certain language constructs (like the type contexts in haskell or declarations in C).

	5 Parser Mechanics
		The generated parser inherits from the base parser, and contains one method for each rule in the grammar.
		before the token has been requested by the parser, it may mess up a context-sensitive scanner.
		A potentially useful combination of these fields is to extract the portion of the input matched by the current rule.

	Cyrus' Blather : Only a few hours left (part 3)
		One of which is multi-methods (which are already available in.Net, albeit not in a clear form), the other of which is to implement the well known visitor pattern on this new token hierarchy.
		Specifically, the visitor says that when it "visits" a "class" token that the outer parser ("Parser.this") should start parsing a class, likewise with an interface token.
		We now have a convenient hierarchy for describing tokens in a type safe manner, and we have a Visitor system that allows us to use them flexibly without clutter, while also allowing the code around the token handling to be self-describing.

	Assignment 7v3, CSC430, Winter 2006
		Then, you will tie together your lexer, your parser, and your solution to assignment 4 to produce a working evaluator that reads a file from disk and evaluates it.
		The second defines tokens like left-paren and begin (that is, keywords) that have no associated information.
		All of the capitalized names refer to literal tokens, and all of the lower-case names refer to nonterminals defined in the grammar.

		must be the numeric code for the type of token it has just found, or 0 for end-of-input.
		When a token is referred to in the grammar rules by a name, that name in the parser file becomes an integer constant whose value is the proper numeric code for that token type.
		When a token is referred to in the grammar rules by a character literal, the numeric code for that character is also the code for the token type.

	Parser
		This method calls System.exit() and writes directly to stderr, which is usually not appropriate when a parser is embedded into a larger application.
		Return the token type of the ith token of lookahead where i=1 is the current token being examined by the parser (i.e., it has not been matched yet).
		Throw an exception upon mismatch, which is catch by either the error handler or by the syntactic predicate.

	Using the parser
		The parser structure converts the lexing function produced by ML-Lex into a function which creates a lazy stream of tokens.
		The rest of the token stream includes the end-of-parse symbol which caused the reduction of some rule to the start symbol.
		The function sameToken can be used to see if two tokens denote the same terminal, irregardless of any values that the tokens carry.

	Vizacc Development Blog: HelpMaker Notes Archives
		A RTF token is a command or sequence of commands that tells the display to do something, such as make the text bold, italic, underline, much like HTML tokens.
		A token parser which reads and writes many of the HTML tags means that what is seen in HelpMaker directly translates to what you see in HTML.
