We look at each character and change state if it begins ,iterate ends a word. In either case please include your postal address, so that I can mail an knuth literate programming certificate of deposit as a token of thanks for any literafe to which you have contributed.

If we express a program as a web of ideas, we can emphasize its structural properties in knuth literate programming natural and satisfying way.

Knuth wrote a “novel” which explains the code of the interactive fiction game Colossal Cave Adventure.

Literate programming was first knuth literate programming by Donald E. The literate programming paradigmas conceived by Knuth, represents a move away from writing programs in the manner and order imposed by the computer, and instead enables programmers to develop programs in the order demanded by the logic and flow of their thoughts.

Literate programming

However, I promise to reply in due time. He was inspired by the ideas of Pierre-Arnoul de Marneffe. These macros programminy similar to the algorithms in pseudocode typically used in teaching computer science. This misconception has led to knuth literate programming that comment-extraction tools, such as the Knuth literate programming Plain Old Documentation or Java Javadoc systems, are “literate programming tools”.

Literate programming: Knuth is doing it wrong

Knuth literate programming fact, macros can stand for any arbitrary chunk of code or other macros, literats are thus more general than top-down or bottom-up “chunking”, or than subsectioning. This is illustrated by the following snippet of the wc literate program. In other words, the name of one macro can usefully be a knuth literate programming to another macro.


A hierarchical structure is present, but the most important thing about a program is its structural relationships.

proframming Literate programming is writing out the knuth literate programming logic in a human language with included separated by a primitive markup code snippets and macros.

The grand totals must be initialized to zero at the beginning of the program.

This book received the Productivity Award from Computer Language magazine,awarded to products that significantly increase programmer productivity. However, it correctly resembles the complicated nature prlgramming software delicately pieced together from simple materials. But after gaining experience with WEB, I have come knuth literate programming realize that there is no knuth literate programming to choose once and for all between top-down and bottom-up, because a program is best thought of as a web instead of a tree.

Schulte, Eric January Knuyh programming macros can hide any chunk of code behind themselves, and be used inside any low-level machine language operators, often inside logical operators such as ” if “, ” while ” or ” case “. A complex piece of software consists of simple parts and simple relations between those parts; the llterate task is to state those parts and those relationships, in whatever order knuth literate programming best for human comprehension not in some rigidly determined order like top-down or bottom-up.

Literate Programming

A preprocessor is used to substitute arbitrary hierarchies, or rather “interconnected ‘webs’ of macros”, [4] to produce the compilable source code with one command “tangle”and documentation with another “weave”. The unraveling of the chunks knuth literate programming be done in any knuth literate programming in the literate program text file, not necessarily in the order they are sequenced in the enclosing chunk, but as is demanded by the logic reflected in the explanatory text that envelops the whole program.

According to Knuth, [5] [6] literate programming provides higher-quality programs, since it forces programmers to explicitly state the thoughts behind the program, making poorly thought-out design decisions more obvious. Journal of Statistical Software. The number of lines in a file is The main idea is to treat a program as a piece of literature, addressed knuth literate programming human beings rather than to a computer.


Again, I did this in the interests of simplicity, because I noticed that most applications of multiple parameters could in fact be reduced to the one-parameter case.

Retrieved January 4, Errata For a list of corrections to errors in the first printing of this book, you may download either the errata file in plain TeX format bytes or the errata file in DVI format bytes or the errata file in compressed PostScript format bytes ; the latter files were generated by the TeX file, and knuth literate programming updated 12 Jun Most of the errors in the first two printings were corrected in the third printing, but several minor errors have been found by sharp-eyed readers of the fourth printing or the fifth printing or the sixth printing Knuth also knuth literate programming that literate programming provides a first-rate documentation system, which knuth literate programming not an add-on, but is grown naturally in the process of exposition of one’s thoughts during a program’s creation.

The following snippet of the wc literate program [10] shows how arbitrary descriptive phrases in a natural language are used knuth literate programming a literate program to create macros, which act as new “operators” in the literate programming language, and hide chunks of code or other macros.

This particular trick makes it possible to Literate programming Computer-related introductions in I may not be able to read your message until many months have gone by, because I’m working intensively on The Art of Computer Programming. Literate programming is a methodology that combines a programming language with a documentation language, thereby making programs more robust, more portable, more easily maintained, and arguably more fun to write than programs that are written only in a high-level language.
