Docstring
In programming, a docstring is a string literal specified in source code that is used, like a comment, to document a specific segment of code. Unlike conventional source code comments, or even specifically formatted comments like docblocks, docstrings are not stripped from the source tree when it is parsed and are retained throughout the runtime of the program. This allows the programmer to inspect these comments at run time, for instance as an interactive help system, or as metadata. Languages that support docstrings include Python, Lisp, Elixir, Clojure, Gherkin, Julia and Haskell. Implementation examples Elixir Documentation is supported at language level, in the form of docstrings. Markdown is Elixir's de facto markup language of choice for use in docstrings: def module MyModule do @moduledoc """ Documentation for my module. With **formatting**. """ @doc "Hello" def world do "World" end end Lisp In Lisp, docstrings are known as documentation strings. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doctest
doctest is a module included in the Python programming language's standard library that allows the easy generation of tests based on output from the standard Python interpreter shell, cut and pasted into docstrings. Implementation specifics Doctest makes innovative use of the following Python capabilities: * docstrings * The Python interactive shell (both command line and the included idle application) * Python introspection When using the Python shell, the primary prompt: >>> , is followed by new commands. The secondary prompt: ... , is used when continuing commands on multiple lines; and the result of executing the command is expected on following lines. A blank line, or another line starting with the primary prompt is seen as the end of the output from the command. The doctest module looks for such sequences of prompts in a docstring, re-executes the extracted command and checks the output against the output of the command given in the docstrings test example. The default a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comment (computer Programming)
In computer programming, a comment is a programmer-readable explanation or '' annotation'' in the source code of a computer program. They are added with the purpose of making the source code easier for humans to understand, and are generally ignored by compilers and interpreters.Source code can be divided into ''program code'' (which consists of machine-translatable instructions); and ''comments'' (which include human-readable notes and other kinds of annotations in support of the program code). The syntax of comments in various programming languages varies considerably. Comments are sometimes also processed in various ways to generate documentation external to the source code itself by documentation generators, or used for integration with source code management systems and other kinds of external programming tools. The flexibility provided by comments allows for a wide degree of variability, but formal conventions for their use are commonly part of programming style guides ...

Epydoc
Epydoc is a documentation generator that processes its own lightweight markup language Epytext for Python documentation strings. As opposed to freeform Python docstrings, reStructuredText (both also supported) and other markup languages for docstrings, Epytext supports linking between different pieces of documentation. The project Epydoc is inactive since February 2009. Epydoc is released under the MIT license. There are several tools for rendering Epytext. Most commonly, the epydoc program is used to render Epytext as a series of HTML documents for display on the Internet, or as a PDF document for printing. Epydoc also supports viewing the rendered documentation within Python using a GUI. The syntax is uncomplicated enough for the programmer to read the raw Epytext docstrings embedded in the source code directly.

Clojure
Clojure (, like ''closure'') is a dynamic and functional dialect of the Lisp programming language on the Java platform. Like other Lisp dialects, Clojure treats code as data and has a Lisp macro system. The current development process is community-driven, overseen by Rich Hickey as its benevolent dictator for life (BDFL). Clojure advocates immutability and immutable data structures and encourages programmers to be explicit about managing identity and its states. This focus on programming with immutable values and explicit progression-of-time constructs is intended to facilitate developing more robust, especially concurrent, programs that are simple and fast. While its type system is entirely dynamic, recent efforts have also sought the implementation of a dependent type system. History and development process Rich Hickey is the creator of the Clojure language. Before Clojure, he developed dotLisp, a similar project based on the .NET platform, and three earlier a ...

Elixir (programming Language)
Elixir is a functional, concurrent, general-purpose programming language that runs on the BEAM virtual machine which is also used to implement the Erlang programming language. Elixir builds on top of Erlang and shares the same abstractions for building distributed, fault-tolerant applications. Elixir also provides productive tooling and an extensible design. The latter is supported by compile-time metaprogramming with macros and polymorphism via protocols. Elixir is used by companies such as Ramp, PagerDuty, Discord, Brex, E-MetroTel, Pinterest, Moz, Bleacher Report, The Outline, Inverse, Divvy, FarmBot and for building embedded systems. The community organizes yearly events in the United States, Europe, and Japan, as well as minor local events and conferences. History José Valim is the creator of the Elixir programming language, a research and development project created at Plataformatec. His goals were to enable higher extensibility and productivity in the Erlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

String Literal
A string literal or anonymous string is a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally " bracketed delimiters", as in x = "foo", where "foo" is a string literal with value foo. Methods such as escape sequences can be used to avoid the problem of delimiter collision (issues with brackets) and allow the delimiters to be embedded in a string. There are many alternate notations for specifying string literals especially in complicated cases. The exact notation depends on the programming language in question. Nevertheless, there are general guidelines that most modern programming languages follow. Syntax Bracketed delimiters Most modern programming languages use bracket delimiters (also balanced delimiters) to specify string literals. Double quotations are the most common quoting delimiters used: "Hi There!" An empty string is literally written by a pair of quotes with no character ...

Common Lisp
Common Lisp (CL) is a dialect of the Lisp programming language, published in ANSI standard document ''ANSI INCITS 226-1994 (S20018)'' (formerly ''X3.226-1994 (R1999)''). The Common Lisp HyperSpec, a hyperlinked HTML version, has been derived from the ANSI Common Lisp standard. The Common Lisp language was developed as a standardized and improved successor of Maclisp. By the early 1980s several groups were already at work on diverse successors to MacLisp: Lisp Machine Lisp (aka ZetaLisp), Spice Lisp, NIL and S-1 Lisp. Common Lisp sought to unify, standardise, and extend the features of these MacLisp dialects. Common Lisp is not an implementation, but rather a language specification. Several implementations of the Common Lisp standard are available, including free and open-source software and proprietary products. Common Lisp is a general-purpose, multi-paradigm programming language. It supports a combination of procedural, functional, and object-oriented programming para ...

Computer Programming
Computer programming is the process of performing a particular computation (or more generally, accomplishing a specific computing result), usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, Profiling (computer programming), profiling algorithms' accuracy and resource consumption, and the implementation of algorithms (usually in a chosen programming language, commonly referred to as coding). The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the Domain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doxygen
Doxygen ( ) is a documentation generator and static analysis tool for software source trees. When used as a documentation generator, Doxygen extracts information from specially-formatted comments within the code. When used for analysis, Doxygen uses its parse tree to generate diagrams and charts of the code structure. Doxygen can cross reference documentation and code, so that the reader of a document can easily refer to the actual code. Doxygen is free software, released under the terms of the GNU General Public License version2 (GPLv2). Design Like Javadoc, Doxygen extracts documentation from source file comments. In addition to the Javadoc syntax, Doxygen supports the documentation tags used in the Qt toolkit and can generate output in HyperText Markup Language (HTML) as well as in Microsoft Compiled HTML Help (CHM), Rich Text Format (RTF), Portable Document Format (PDF), LaTeX, PostScript or man pages.
