		Toy Parser Generator for Python TPG is a parser generator for Python.
		IBM's DOM Implementation in C++ XML for C++ parser (XML4C) is a validating XML parser written in a portable subset of C++.
		It uses an annotated corpus, and produces a parser by using ILP for inducing the rules that control the actions of a shift-reduce parser.

	LR parser - Wikipedia, the free encyclopedia
		In typical use when we refer to an LR parser we mean a particular parser capable of recognizing a particular language specified by a context free grammar.
		Of all parsers that scan their input left to right, LR parsers detect syntactic errors (that is, when the input does not conform to the grammar) as soon as possible.
		LR parsers are difficult to produce by hand; they are usually constructed by a parser generator or a compiler-compiler.

	LALR parser - Wikipedia, the free encyclopedia
		Look-Ahead LR parsers or LALR parsers are a specialized form of LR parsers that can deal with more context-free grammars than Simple LR parsers but less than LR(1) parsers can.
		It is a very popular type of parser because it gives a good trade-off between the number of grammars it can deal with and the size of the parsing tables it requires.
		It is these types of parsers that are generated by compiler-compilers such as yacc and GNU bison.

		Der eigentliche Parser als Implementierung eines abstrakten Automaten (meist realisiert als Kellerautomat) kümmert sich dagegen um die Grammatik der Eingabe, führt eine syntaktische Überprüfung der Eingangsdaten durch und erstellt in der Regel aus den Daten einen Ableitungsbaum (in Anlehnung an das Englische gelegentlich auch als Parse-Baum bezeichnet).

	Parser (Site not responding. Last check: 2007-10-29)
		A parser is a computer program or a component of aprogram that analyses the grammatical structure of an input, with respect to a given formal grammar, aprocess known as parsing.
		Such parsers are usually not written by hand but generated by parser generators.
		A parser can do this in essentially two ways: it can start with the input and attempt to rewrite it to the start symbol,a so-called bottom-up parser, or it can start with thestart symbol and try to rewrite it to the input, a so-called top-down parser.

	Constructing the Parsing Tables (Site not responding. Last check: 2007-10-29)
		Such parsers have many thousands of states for a typical programming language and are thus large.
		SLR parsing is the weakest method in terms of the number of grammars it can handle.
		LALR parsers have the same number of states as the equivalent SLR parser but they are harder to construct.

	[No title]
		Introduction This document describes the use of the SLR(1) parser generator whose executable image is found in file descartes:/u/cs444/slr.
		RESULT: If the grammar is free of errors and if the `-t' flag is not given, slr parsing tables are generated in a file named `gram.tbl', where `gram' is the name of the input file holding the grammar.
		Program Input The input to the SLR generator is a context-free (hopefully SLR(1)) grammar.

	Essence, an LR parser generator for Scheme (Site not responding. Last check: 2007-10-29)
		The generated parsers perform error recovery, and are highly efficient.
		Rather, the parser generator results from a general parser which takes the input grammar as a parameter; no generation and recompilation is necessary to try out changes to a grammar.
		The generated parsers result from the general parser by an automatic program transformation called partial evaluation.

		PyGgy is a python package for generating parsers and lexers in python.

		Because GLR parsing is used, the parser can deal with arbitrary grammars, even if they are recursive or ambiguous.

	LR parser
		It isn't uncommon, however, to refer to an LR parser meaning a driver program that can be supplied with a suitable table to produce a wide number of different particular LR parsers.
		Of all parsers that scan their input left to right, LR parsers detect syntactic errors (that is, when their input doesn't conform to the grammar) as soon as it possible to do.
		The item E → E · + B, for example, indicates that the parser has recognized a string corresponding with E on the input stream and now expects to read a '+' followed another string corresponding with E. Item sets

	LALR parser (Site not responding. Last check: 2007-10-29)
		In computer programming, an LALR parser or Look-ahead LR(left to right) parser is a specific type of LR parser that can deal with more context-free grammars than SLR parsers but less than LR(1) parserss can.
		Like SLR, LALR is a refinement to the technique for constructing LR(0) parse tables.
		While SLR uses FOLLOW sets to construct reduce actions, LALR uses LOOKAHEAD sets, which are more specific because they take more of the parsing context into account.
