	Metaprogramming - Wikipedia, the free encyclopedia
		Metaprogramming is the writing of programs that write or manipulate other programs (or themselves) as their data or that do part of the work that is otherwise done at compile time during runtime.
		The most common metaprogramming tool is a compiler which allows a programmer to write a relatively short program in a high-level language and uses it to write an equivalent assembly language or machine language program.
		Another still fairly common example of metaprogramming might be found in the use of lex (see also: flex) and yacc (see also: bison), which are used to generate lexical analysers and parsers.

	[No title]
		Metaprogramming isn't particularly complicated idea to formalize, once you decide to do it; actually, all the underlying ideas already exist, and await to be gathered into a coherent whole.
		Such a framework would contain all the tools necessary to programming and metaprogramming, and the sources of said tools would not only be freely available in their whole entirety, but would be designed so as to be semi-automatically managed, by the system, under the guidance of the developers.
		Metaprogramming and free availability of sources consist in opening programs to all processing and modifications, made by man or by the machine; all in all, it's a matter of opening programs to intelligibility, of participating in a process of building a shared knowledge, that is, of science!

	John Lilly - Programming & Metaprogramming in the Human Biocomputer
		The national negative program on LSD was launched; LSD was the big scare, on a par with War, Pestilence, and Famine as the destroyer of young brains, minds and fetuses.
		Metaprogramming appears at a critical cortical size-the cerebral computer must have a large enough number of interconnected circuits of sufficient quality for the operations of metaprogramming to exist in that biocomputer.
		Above all these metaprograms to be experimented upon is one metaprogram of value to this subject his overall policy is the intent to explore, to observe, to analyze.

	Important comments by Dr. John Lilly
		Metaprogram: a set of instructions, descriptions, and means of control of sets of programs.
		Program: a set of internally consistent instructions for the computation of signals, the formations of information, the storage of both, the preparation of messages, the logical processes to be used, the selection processes, and the storage addresses all occurring within a biocomputer, a brain.
		Self-Metaprogram: a special metaprogram which involves the self-programming aspects of the computer, which creates new programs, revises old programs, and reorganizes programs and metaprograms.

	C++ Templates: Metaprograms > A First Example of a Metaprogram (Site not responding. Last check: 2007-10-21)
		Metaprogramming consists of “programming a program.” In other words, we lay out code that the programming system executes to generate new code that implements the functionality we really want.
		Usually the term metaprogramming implies a reflexive attribute: The metaprogramming component is part of the program for which it generates a bit of code/program.
		Although this program wasn’t strictly portable (error messages aren’t standardized), the program did show that the template instantiation mechanism is a primitive recursive language that can perform nontrivial computations at compile time.

	Template metaprogramming - Wikipedia, the free encyclopedia
		Template metaprogramming is a programming technique in which templates are used by a compiler to generate temporary source code, which is merged by the compiler with the rest of the source code and then compiled.
		Template metaprograms have no mutable variables— that is, no variable can change value once it has been initialized, therefore template metaprogramming can be seen as a form of functional programming.
		Metaprograms can thus be difficult to maintain by programmers inexperienced in template metaprogramming (though this may vary with the language's implementation of template metaprogramming syntax).

	Meta Programming
		A metaprogram is a program that manipulates other programs (or itself) as its data.
		Metaprogramming is what you do with CeePlusPlus templates or CommonLisp macros: defining the content of (part of) a program by writing code that generates it.
		Writing a translator for a general purpose programming language is outside the scope of this discussion--we all know why this is done, and agree that it should be.

	Erowid Metaprogramming Vaults : "Get With the Metaprogram" by James Kent
		Metaprogramming begins in that split second when a pre-scripted program consciously begins to rewrite itself.
		Yes, everyone has a program for you, and failure to comply with the program can result in excommunication, deportation, arrest, disownment, death, and a downright snubbing.
		A short program built with sturdy, unwavering constructs may seem tempting, but such a system is much harder to upgrade, and is destined to become obsolete with the passing of time.

	LWN: Metaprogramming using Scheme
		"Metaprogramming -- programming with code generators or writing programs that themselves write code -- has numerous useful attributes, such as simplifying code maintenance and making it easier to craft boilerplate code.
		The first article of this series explained why metaprogramming is necessary, looked at some of the components of metaprogramming, showed how to build a code generator, and introduced language-sensitive macro programming.
		In this article, learn techniques and applications of metaprogramming in the Scheme programming language, and see how macros are programmed and how they can make your large-scale programming tasks significantly easier.

	Template Metaprogramming - ©2001 Josh Walker (Site not responding. Last check: 2007-10-21)
		Metaprogramming can facilitate increased performance by computing performance-critical results at compile time or using compile-time logic to choose the best algorithm for the job.
		The basic tools of metaprogramming consist of constructions that should be familiar to most C++ programmers: compile-time constants, typedefs, template specialization, and recursive templates.
		The mechanics of metaprogramming may require a readjustment from the regular C++ programmer, since the C++ metaprogramming sublanguage resembles a dynamically-typed functional language.

		A metaprogram is a program that generates or manipulates program code.
		Ever since generic programming was introduced to C++, programmers have discovered myriad "template tricks" for manipulating programs as they are compiled, effectively eliminating the barrier between program and metaprogram.

	Programming and Metaprogramming in the Human Biocomputer
		In this atmosphere (1966-1967) Programming and Metaprogramming in The Human Biocomputer was written.
		The basic belief that one could leave the body and explore new universes was succesfully programmed in the first eight different experiments lasting from five minutes to forty minutes; the later eight experiments were on the cognitional multidimensional space without the leaving the body metaprogram (see previous section on Projection for the cognition space phenomenon).
		With this program the subject found old models in himself (old programs, old metaprograms, implanted by others, implanted by self, injected by parents, by teachers, etc.) He found that these were disparate and separate autonomous beings in himself.

		He proposed the notion that inasmuch as the brain can be considered the hardware of the mind, the linguistic models that the brain uses to interpret the world -- programs -- can be modified and refined at the discretion of the metaprogrammer.

	Multi-stage Programming Homepage
		In addition to having the usual constructs of a general-purpose language, multi-stage languages internalize the notions of runtime program generation and execution.
		Thus, multi-stage languages provide the programmer with the essence of partial evaluation and program specialization techniques, both of which have been shown to lead to dramatic resource-utilization gains in a wide range of applications, starting from implementations of domain-specific compilers, to high-performance operating systems.
		Multi-stage languages make it possible to write generic and highly-parameterized programs that do not pay unnecessary runtime overheads.
