According to Knuth, [5] [6] literate programming provides higher-quality programs, since it forces programmers to knuth literate programming state the thoughts behind the program, making poorly thought-out design decisions more obvious. This misconception has led to claims that comment-extraction tools, such as the Perl Plain Old Documentation or Java Javadoc systems, are “literate programming tools”. Retrieved from ” https: This book received the Productivity Award from Computer Language magazine,awarded to products that significantly increase programmer productivity.

If we made these variables local to main, we would have to do this initialization explicitly; however, C globals are automatically zeroed.

Instead of comments provided as side notes to source code a knuth literate programming program contains the explanation of concepts on each level, with knuth literate programming level concepts deferred to their appropriate place, which allows for better communication of thought. I hope the version is otherwise error-free.

Knuth also claims that literate programming provides a first-rate documentation system, which is not an add-on, but is grown naturally in the process of exposition of one’s thoughts knuth literate programming a program’s creation. This differs from traditional documentation, in which a programmer is presented with source code knuth literate programming follows a compiler-imposed order, and must decipher the thought process behind the program from the code and its associated comments.

Knuth had privately used a literate programming system called DOC as early as 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 knuth literate programming a high-level language.

Literate 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 “.

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

Such exposition of ideas creates the flow of thought that is like a literary work.

Ljterate understand a complicated system by understanding its simple parts, and by understanding the simple relations between those parts and their immediate neighbors. A hierarchical structure is present, but the most important thing about a program is knuth literate programming structural relationships. Webarchive template wayback links CS1 errors: Journal of Statistical Software.

Literate Programming, Knuth

These macros are similar to the knuth literate programming in pseudocode typically used in teaching computer science. Literate programming is writing out the program logic in a human language with included separated by knuth literate programming primitive markup code snippets and macros. In either case please include your postal address, so that I can mail an official certificate of deposit as a token of thanks for any improvements to which you have contributed.

The first published knuth literate programming programming environment was WEBintroduced by Donald Knuth in for his TeX typesetting system; it uses Pascal as its underlying programming language and TeX for typesetting of the documentation.

Literate programming is very often misunderstood [8] to refer only to formatted documentation produced from a common file with both source code and comments — which is properly called documentation generation — or to voluminous commentaries included with code.

In fact, macros can stand for any arbitrary chunk of code or other macros, and are thus more general than top-down or bottom-up “chunking”, or than subsectioning. Please send suggested corrections to knuth-bug cs. 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”.

But as time went on, I’ve become extremely pleased with the name, because I think that a complex piece of software is, indeed, best regarded as a web knuth literate programming has been delicately pieced together from simple materials.

There are various other implementations of the literate programming concept some of them don’t have macros and hence violate Order of human logic principle:.
