Binary Repository Manager
A software repository, or repo for short, is a storage location for software packages. Often a table of contents is also stored, along with metadata. A software repository is typically managed by source or version control, or repository managers. Package managers allow automatically installing and updating repositories, sometimes called "packages". Overview Many software publishers and other organizations maintain servers on the Internet for this purpose, either free of charge or for a subscription fee. Repositories may be solely for particular programs, such as CPAN for the Perl programming language, or for an entire operating system. Operators of such repositories typically provide a package management system, tools intended to search for, install and otherwise manipulate software packages from the repositories. For example, many Linux distributions use Advanced Packaging Tool (APT), commonly found in Debian based distributions, or Yellowdog Updater, Modified ( yum) found in ...

Package Format
Package format is a type of archive containing computer programs and additional metadata needed by package managers; an instance of this type of archive is called a package. While the archive file format itself may be unchanged, package formats carry additional metadata, such as a manifest file or certain directory layouts. Packages may contain either source code or executable files. Packages may be converted from one type to another with software such as Alien. Software supply chain and security Packages are an important component in managing the security and integrity of the software supply chain. Packages containing executables and configuration can be digitally signed to establish the integrity of running software and protect against tampering. Package formats that support code signing include .deb (Debian), .msi (Microsoft Windows), .apk ( Android) and .ipa (IOS, IPadOS). Common formats Specialized formats BSD-based formats Linux-based formats Windows f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cabal (software)
The Cabal (common architecture for building applications and libraries) is a type of package manager to aid in packaging and distributing software packages, in the forms of application software and libraries, for the programming language Haskell. History Cabal was introduced to simplify packaging of Haskell software and modules. It was added to the Glasgow Haskell Compiler in version 6.4 as the default package manager, alongside GHC's internal manager ''ghc-pkg''. Its approach has changed significantly over the course of its development, moving from global package installation to sandboxed builds, and eventually a Nix-inspired solution of local builds with global caching, which became the default in 2019. 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 automated downloading, compiling In computing, a compiler is a ...

Hackage
Haskell () is a general-purpose, statically typed, purely functional programming language with type inference and lazy evaluation. Designed for teaching, research, and industrial applications, Haskell pioneered several programming language features such as type classes, which enable type-safe operator overloading, and monadic input/output (IO). It is named after logician Haskell Curry. Haskell's main implementation is the Glasgow Haskell Compiler (GHC). Haskell's semantics are historically based on those of the Miranda programming language, which served to focus the efforts of the initial Haskell working group. The last formal specification of the language was made in July 2010, while the development of GHC continues to expand Haskell via language extensions. Haskell is used in academia and industry. , Haskell was the 28th most popular programming language by Google searches for tutorials, and made up less than 1% of active users on the GitHub source code repository.

Package Development Process
A software package development process is a system for developing software packages. Such packages are used to reuse and share code, e.g., via a software repository. A package development process includes a formal system for package checking that usually exposes bugs, thereby potentially making it easier to produce ''trustworthy software'' ( Chambers' ''prime directive''). It may also include a standard for documentation, thereby making it easier for new users to learn how to use it. Discussion In this context, a ''package'' is a collection of functions written for use in a single language such as Python or R. It may also be bundled with documentation. For many programming languages, there are software repositories where people share such packages. For example, a Python package combines documentation, code and initial set up and possibly examples that could be used as unit tests in a single file with a "py" extension. By contrast, an R package has documentation with exampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...

Automated Testing
In software testing, test automation is the use of software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or perform additional testing that would be difficult to do manually. Test automation is critical for continuous delivery and continuous testing. General approaches There are many approaches to test automation, however below are the general approaches used widely: * Graphical user interface testing. A testing framework that generates user interface events such as keystrokes and mouse clicks, and observes the changes that result in the user interface, to validate that the observable behavior of the program is correct. * API driven testing. A testing framework that uses a programming interface to the application to validate the behaviour under test. Typically API driven te ...

CRAN (R Programming Language)
R packages are software extension, extensions to the R (programming language), R statistical programming language. R packages contain code, data, and documentation in a standardised collection format that can be installed by users of R, typically via a centralised software repository such as CRAN (the Comprehensive R Archive Network). The large number of packages available for R, and the ease of installing and using them, has been cited as a major factor driving the widespread adoption of the language in data science. Compared to Library (computing), libraries in other programming languages, R packages must conform to a relatively strict specification. The ''Writing R Extensions'' manual specifies a standard directory structure for R source code, data, documentation, and package metadata, which enables them to be installed and loaded using R's in-built package management tools. Packages distributed on CRAN must meet additional standards. According to John Chambers (statistician), J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R (programming Language)
R is a programming language for statistical computing and Data and information visualization, data visualization. It has been widely adopted in the fields of data mining, bioinformatics, data analysis, and data science. The core R language is extended by a large number of R package, software packages, which contain Reusability, reusable code, documentation, and sample data. Some of the most popular R packages are in the tidyverse collection, which enhances functionality for visualizing, transforming, and modelling data, as well as improves the ease of programming (according to the authors and users). R is free and open-source software distributed under the GNU General Public License. The language is implemented primarily in C (programming language), C, Fortran, and Self-hosting (compilers), R itself. Preprocessor, Precompiled executables are available for the major operating systems (including Linux, MacOS, and Microsoft Windows). Its core is an interpreted language with a na ...

Unit Testing
Unit testing, component or module testing, is a form of software testing by which isolated source code is tested to validate expected behavior. Unit testing describes tests that are run at the unit-level to contrast testing at the Integration testing, integration or System testing, system level. History Unit testing, as a principle for testing separately smaller parts of large software systems, dates back to the early days of software engineering. In June 1956 at US Navy's Symposium on Advanced Programming Methods for Digital Computers, H.D. Benington presented the Semi-Automatic Ground Environment, SAGE project. It featured a specification-based approach where the coding phase was followed by "parameter testing" to validate component subprograms against their specification, followed then by an "assembly testing" for parts put together. In 1964, a similar approach is described for the software of the Project Mercury, Mercury project, where individual units developed by dif ...
