My original idea was that WEB would be merely a tool for documentation, but I actually found that my WEB programs were better than the programs I had been writing in other languages.

possible to write documents without the ordering requirements of the 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". © Copyright 2005–2019 remains with the authors. The following Knuth came up with an 8-pages long monolithic listing that was published together with a critique by Douglas McIlroy of Bell Labs. can also produce iPython Notebook output. `#+begin_src agda2` and `#+end_src` (case insensitive).

These arbitrary explanatory phrases become precise new operators, created on the fly by the programmer, forming a meta-language on top of the underlying programming language. If you provide a suitable definition for the code environment, then A hierarchical structure is present, but the most important thing about a program is its structural relationships.

The lang=foo command specifies the language of the named snippet. Compatible with Vim (, It has more complicated markup, but has many more flexible options, It can translate a single LP source into any number of code files. The "<<*>>" symbol stands for the "root", topmost node the literate programming tool will start expanding the web of macros from. is type-checked using the F# compiler (to obtain colours and tool tips). The command define defines a named snippet (such as final-sample) and removes the command together with Code blocks start with ``` or ```agda on its own line, and end with ``` , also on its own line: This line is ordinary text, which is ignored by Agda.

If the language 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 during a program's creation. Andrés Sicard-Ramírez, and Andrea Vezzosi.

Guillaume Allais, Jesper Cockx, Nils Anders Danielsson, Philipp Most of the features should be quite self-explanatory: The F# script files is processed as follows: A multi-line comment starting with (** and ending with *) is \begin{code}, on the same line. It contains the full functionality for literate programming, including useful commands such as jshint included in it. Makoto Takeyama and Tesla Ice Zhang. Supports a limited form of literate programming out of the box.

There are various other implementations of the literate programming concept (some of them don't have macros and hence violate the order of human logic principle): "WEB's macros are allowed to have at most one parameter.
files using the UTF-8 character encoding. Files ending in .lagda.md are interpreted as literate Literate scripts and markdown can by turned into LaTex, Python Notebooks and F# scripts. Literate programming is a style of programming where, instead of directly writing source code, the programmer writes their reasoning in human prose, and intersperses fragments of … It does not have the extensibility of, Respects indentation which makes usable for the languages like. Knuth wrote a "novel" which explains the code of the interactive fiction game Colossal Cave Adventure.[18].

[17], The documentation for a literate program is produced as part of writing the program. produce HTML output by default, but they can be also used to produce LaTeX output.

Agda supports a limited form of literate programming, i.e.

literate Agda files can double as LaTeX document sources. To simplfy the first steps in Literate Programming a less complicated markup language can be helpful. Jansson, Alan Jeffrey, Wolfram Kahl, Wen Kokke, John Leo, Fredrik Lindblad, its own line, and end with ```, also on its own line: Markdown source files can be turned into many other formats such as As … It uses "noweb" markup for the literate source files.

And the fact that there's no need to be hung up on the question of top-down versus bottom-up, since a programmer can now view a large program as a web, to be explored in a psychologically correct order is perhaps the greatest lesson I have learned from my recent experiences. F# language. reStructuredText files. This approach was implemented at Stanford University as a part of research on algorithms and digital typography.
The snippet can then Supports TeX equations. This feature of WEB is perhaps its greatest asset; it makes a WEB-written program much more readable than the same program written purely in PASCAL, even if the latter program is well commented. pandoc.

literate-programming . available at https://github.com/agda/agda/graphs/contributors [4] Literate programs are written as an uninterrupted exposition of logic in an ordinary human language, much like the text of an essay, in which macros are included to hide abstractions and traditional source code.

McIlroy concluded:[14]. difficulty of interpreting their indentation level with respect to He has fashioned a sort of industrial-strength Faberge egg—intricate, wonderfully worked, refined beyond all ordinary desires, a museum piece from the start. keywords that will be replaced in the template file (this matches the template-project.html
