Haddock (software)
Haddock is a free, portable command-line program documentation generator for Haskell. It is influenced by IDoc, HDoc, and Doxygen. It produces hyperlinked HTML files from annotated Haskell (the documentation is embedded in comments) source files, with additional information extracted from type annotations; it supports only partially generating documentation in SGML. It is often used in conjunction with darcs and Cabal. It is dependent on Glasgow Haskell Compiler (GHC), using a modified form of the HsParser (written in Happy) parser for Haskell included in GHC. Its lightweight markup is based on IDoc's.

Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs, t ...

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. ...

XMonad
xmonad is a dynamic window manager (tiling) for the X Window System, noted for being written in the functional programming language Haskell. Window manager Begun in March 2007, version 0.1 was announced in April 2007 as 500 lines of Haskell. xmonad is a tiling window manager—akin to dwm, larswm, and StumpWM. It arranges windows in a non-overlapping pattern, and enables managing windows without using the mouse. xmonad is packaged and distributed on a wide range of Unix-like operating systems, such as a large number of Linux distributions, and BSD systems. While originally a clone of dwm (derivative in areas such as default keybindings), xmonad now supports features not available to dwm users such as per-workspace layout, tiling reflection, state preservation, layout mirroring, GNOME support and per-screen status bars; it can be customised by modifying an external configuration file and 'reloaded' while running. xmonad features have begun to influence other tiling window m ...

Haskell Platform
The Haskell Platform is a collection of software packages, tools and libraries that create a common platform for using and developing applications in Haskell. With the Haskell Platform, Haskell follows the same principle as Python: "Batteries included". Since 2022, the Haskell Platform has been deprecated. Motivation The Haskell Platform aims to unify Haskell development tools into a single package, consisting of a compiler, compiling tools and many standard libraries, therefore making it easier to develop and deploy full-featured Haskell-driven applications. Packages included Currently it consists of: * GHC, Haskell's flagship compiler * The GHC- Profiler * GHCi, GHCs bytecode- interpreter * The GHCi-Debugger * Alex, a lexer generator, similar to Lex * Happy, a parser generator, similar to Yacc * Cabal, a package manager * Haddock, a documentation tool * hsc2hs, a preprocessor for binding Haskell to C code, allowing C libraries to be used from Haskell * various librarie ...

Parser
Parsing, syntax analysis, or syntactic analysis is the process of analyzing a string of symbols, either in natural language, computer languages or data structures, conforming to the rules of a formal grammar. The term ''parsing'' comes from Latin ''pars'' (''orationis''), meaning part (of speech). The term has slightly different meanings in different branches of linguistics and computer science. Traditional sentence parsing is often performed as a method of understanding the exact meaning of a sentence or word, sometimes with the aid of devices such as sentence diagrams. It usually emphasizes the importance of grammatical divisions such as subject and predicate. Within computational linguistics the term is used to refer to the formal analysis by a computer of a sentence or other string of words into its constituents, resulting in a parse tree showing their syntactic relation to each other, which may also contain semantic and other information (p-values). Some parsing algor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Happy (software)
Happiness, in the context of mental or emotional states, is positive or pleasant emotions ranging from contentment to intense joy. Other forms include life satisfaction, well-being, subjective well-being, flourishing and eudaimonia. Since the 1960s, happiness research has been conducted in a wide variety of scientific disciplines, including gerontology, social psychology and positive psychology, clinical and medical research and happiness economics. Definitions "Happiness" is subject to debate on usage and meaning, and on possible differences in understanding by culture. The word is mostly used in relation to two factors: * the current experience of the feeling of an emotion (affect) such as pleasure or joy, or of a more general sense of 'emotional condition as a whole'. For instance Daniel Kahneman has defined happiness as "''what I experience here and now''". This usage is prevalent in dictionary definitions of happiness. * appraisal of life satisfaction, such as of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glasgow Haskell Compiler
The Glasgow Haskell Compiler (GHC) is an open-source native code compiler for the functional programming language Haskell. It provides a cross-platform environment for the writing and testing of Haskell code and it supports numerous extensions, libraries, and optimisations that streamline the process of generating and executing code. GHC is the most commonly used Haskell compiler. The lead developers are Simon Peyton Jones and Simon Marlow. History GHC originally started in 1989 as a prototype, written in LML (Lazy ML) by Kevin Hammond at the University of Glasgow. Later that year, the prototype was completely rewritten in Haskell, except for its parser, by Cordelia Hall, Will Partain, and Simon Peyton Jones. Its first beta release was on 1 April 1991 and subsequent releases added a strictness analyzer as well as language extensions such as monadic I/O, mutable arrays, unboxed data types, concurrent and parallel programming models (such as software transactional memory and dat ...

Cabal (software)
The Haskell Cabal (''common architecture for building applications and libraries'') aids in the packaging and distribution of software packages. It is contained in the Haskell Platform. History Cabal has been introduced to simplify packaging of Haskell software and modules. It was added to the Glasgow Haskell Compiler version 6.4 as default package manager, along GHC's internal manager ghc-pkg. The actual binary cabal and the library Cabal are developed in different packages. Throughout its development it has gained additional features, such as sandboxes, which allow to escape the so-called Cabal hell (see below). Use Cabal packages provide a standard set of metadata and build process; thus, it is possible to develop tools to upload Cabal packages to the CPAN-like community repository of software, Hackage, or even allow for automated downloading, compilation, and installation of desired packages from Hackage. Criticism Cabal previously used a global package repository by d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darcs
Darcs is a distributed version control system created by David Roundy. Key features include the ability to choose which changes to accept from other repositories, interaction with either other local (on-disk) repositories or remote repositories via SSH, HTTP, or email, and an unusually interactive interface. The developers also emphasize the use of advanced software tools for verifying correctness: the expressive type system of the functional programming language Haskell enforces some properties, and randomized testing via QuickCheck verifies many others. The name is a recursive acronym for Darcs Advanced Revision Control System. Model Darcs treats patches as first-class citizens. For the user, a repository can be seen as a set of patches, where each patch is not necessarily ordered with respect to other patches, i.e. the set of patches is only a partially ordered set. In many cases patches can be independently transmitted between various repositories. Many branching, merging, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SGML
The Standard Generalized Markup Language (SGML; ISO 8879:1986) is a standard for defining generalized markup languages for documents. ISO 8879 Annex A.1 states that generalized markup is "based on two postulates": * Declarative: Markup should describe a document's structure and other attributes rather than specify the processing that needs to be performed, because it is less likely to conflict with future developments. * Rigorous: In order to allow markup to take advantage of the techniques available for processing, markup should rigorously define objects like programs and databases. DocBook SGML and LinuxDoc are examples which used SGML tools. Standard versions SGML is an ISO standard: "ISO 8879:1986 Information processing – Text and office systems – Standard Generalized Markup Language (SGML)", of which there are three versions: * Original ''SGML'', which was accepted in October 1986, followed by a minor Technical Corrigendum. * ''SGML (ENR)'', in 1996, resul ...

Type Signature
In computer science, a type signature or type annotation defines the inputs and outputs for a function, subroutine or method. A type signature includes the number, types, and order of the arguments contained by a function. A type signature is typically used during overload resolution for choosing the correct definition of a function to be called among many overloaded forms. Examples C/C++ In C and C++, the type signature is declared by what is commonly known as a function prototype. In C/C++, a function declaration reflects its use; for example, a function pointer with the signature would be called as: char c; double d; int retVal = (*fPtr)(c, d); Erlang In Erlang, type signatures may be optionally declared, as: -spec(function_name(type1(), type2(), ...) -> out_type()). For example: -spec(is_even(number()) -> boolean()). Haskell A type signature in Haskell generally takes the following form: functionName :: arg1Type -> arg2Type -> ... -> argNType Notice that t ...
