Introduction to metaprogramming

This thoroughly updated edition of The Scheme Programming Language provides an introduction to Scheme and a definitive reference for standard Scheme, presented scheme and the art of programming a clear and concise manner.

Over the s, Friedman and Wise explored the topic in depth and also considered extensions to the world of parallel computing. In the s, Friedman turned to the study of the Scheme programming language. Numerous examples are presented throughout the introductory and reference portions of thetext, and a unique set of extended example programs and applications, with additional exercises, arepresented in the final chapter.

In the macros you simply specify certain parameters, and the M4 processor applies a boilerplate that is specific to both your local installation and sendmail in general. And it comes up with a configuration file for you. For example, Listing 4 is the M4 macro version of a typical sendmail configuration scheme and the art of programming Similarly, autoconf uses M4 to produce shell scripts based on simple macros.

If you've ever installed a program where the first thing you did was type in. Listing 5 is a simple autoconf program that generates a configure program over 3, lines long: The details of the M4 macro processor are too complex to discuss here, but links to more information about the M4 macro processor and its use in sendmail and autoconf are in the Related topics section.

Programs that write programs Now let's turn our attention from generic textual-substitution programs to highly specialized code scheme and the art of programming. We'll review the various programs available, look at sample usage, and build a code generator. The most popular are probably: Flex, a lexical analyzer generator Bison, a parser generator Gperf, a perfect hash-function generator These scheme and the art of programming all generate output for the C language.

You may wonder why these are implemented as code generators instead of as functions. Scheme and the art of programming are several reasons: The inputs to these functions are very complicated and not easily expressible in a form that is valid C code. These programs compute and generate many static lookup tables for operation, and therefore it is better to generate these tables once during pre-compile time than during every invocation of the program.


Many aspects of the functioning of scheme and the art of programming systems are customizable with arbitrary code placed in specific positions. This code can then use variables and functions that are part of the generated structure built by the code generator without having to define and derive all of the variables manually.

Each of these tools is focused on building a particular type of program. Bison is used to generate parsers; Flex is used to generate lexical analyzers.

Other tools are more focused on automating specific aspects of programming. The fact that it proposes the call-by-value evaluation strategy is not always preferable.
