Starlark
Bazel () is a free and open-source software tool used for the automation of building and testing software. Similar to build tools like Make, Apache Ant, and Apache Maven, Bazel builds software applications from source code using rules. Rules and macros are created in the Starlark language, a dialect of Python. There are built-in rules for building software written in Java, Kotlin, Scala, C, C++, Go, Python, Rust, JavaScript, Objective-C, and bash scripts. Bazel can produce software application packages suitable for deployment for the Android and iOS operating systems. History In 2006, Google started the development of a build tool called ''Blaze''. The motivation was to have a build system that provides both speed and correctness in a large monorepo. Bazel was created as an open-source port of Blaze, using its anagram as a name. Bazel was first released in March 2015 and entered beta by September 2015. Version 1.0 was released in October 2019. Rationale Bazel has been ...

Python (programming Language)
Python is a high-level programming language, high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is type system#DYNAMIC, dynamically type-checked and garbage collection (computer science), garbage-collected. It supports multiple programming paradigms, including structured programming, structured (particularly procedural programming, procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC (programming language), ABC programming language, and he first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000. Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions. Python 2.7.18, released in 2020, was the last release of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buck (software)
Buck is a multi-language build system developed and used by Meta Platforms, Inc. It was designed for building small, reusable modules consisting of code and resources within a monorepo. It supports many programming languages, including C++, Swift, Unix Shell, Java, Kotlin, Python, Lua, OCaml, Rust and Go. It can produce binary outputs for a variety of target platforms including iOS, Android, .NET, and Java virtual machine (VM) runtime systems. Licensing for Buck1 is under Apache License 2.0, while Buck2 is under either MIT or Apache 2.0. Buck requires the explicit declaration of dependencies. Because all dependencies are explicit and Buck has a directed acyclic graph of all source files and build targets, Buck can perform incremental recompilation, only rebuilding targets downstream of files that have changed. Buck computes a key for each target that is a hash of the contents of the files it depends on. It stores a mapping from that key to the build target in a build cache. ...

Bourne Shell
The Bourne shell (sh) is a shell command-line interpreter for computer operating systems. It first appeared on Version 7 Unix, as its default shell. Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell—even when other shells are used by most users. The Bourne shell was once standard on all branded Unix systems, although historically BSD-based systems had many scripts written in csh. As the basis of POSIX sh syntax, Bourne shell scripts can typically be run with Bash or dash on Linux or other Unix-like systems; Bash itself is a free clone of Bourne. History Origins Work on the Bourne shell initially started in 1976. Developed by Stephen Bourne at Bell Labs, it was a replacement for the Thompson shell, whose executable file had the same name—sh. The Bourne shell was also preceded by the Mashey shell. Bourne was released in 1979 in the Version 7 Unix release distributed to colleges and univ ...

Mach-O
Mach-O (Mach object) file format, is a file format for executables, object code, shared libraries, dynamically loaded code, and core dumps. It was developed to replace the a.out format. Mach-O is used by some systems based on the Mach kernel. NeXTSTEP, macOS, and iOS are examples of systems that use this format for native executables, libraries and object code. Mach-O file layout Each Mach-O file is made up of one Mach-O header, followed by a series of load commands, followed by one or more segments, each of which contains between 0 and 255 sections. Mach-O uses the REL relocation format to handle references to symbols. When looking up symbols Mach-O uses a two-level namespace that encodes each symbol into an 'object/symbol name' pair that is then linearly searched for, first by the object and then the symbol name. The basic structure—a list of variable-length "load commands" that reference pages of data elsewhere in the file—was also used in the executable file for ...

Sandbox (software Development)
A sandbox is a testing environment that isolates untested code changes and outright experimentation from the production environment or repository in the context of software development, including web development, automation, revision control, configuration management (see also change management), and patch management. Sandboxing protects "live" servers and their data, vetted source code distributions, and other collections of code, data and/or content, proprietary or public, from changes that could be damaging to a mission-critical system or which could simply be difficult to revert, regardless of the intent of the author of those changes. Sandboxes replicate at least the minimal functionality needed to accurately test the programs or other code under development (e.g. usage of the same environment variables as, or access to an identical database to that used by, the stable prior implementation intended to be modified; there are many other possibilities, as the specific fun ...

Amazon Web Services
Amazon Web Services, Inc. (AWS) is a subsidiary of Amazon.com, Amazon that provides Software as a service, on-demand cloud computing computing platform, platforms and Application programming interface, APIs to individuals, companies, and governments, on a metered, pay-as-you-go basis. Clients will often use this in combination with elasticity (system resource), autoscaling (a process that allows a client to use more computing in times of high application usage, and then scale down to reduce costs when there is less traffic). These cloud computing web services provide various services related to networking, compute, storage, middleware, Internet of things, IoT and other processing capacity, as well as software tools via AWS server farms. This frees clients from managing, scaling, and patching hardware and operating systems. One of the foundational services is Amazon Elastic Compute Cloud (EC2), which allows users to have at their disposal a Virtualization, virtual Computer clus ...

Clojure
Clojure (, like ''closure'') is a dynamic programming language, dynamic and functional programming, functional dialect (computing), dialect of the programming language Lisp (programming language), Lisp on the Java (software platform), Java platform. Like most other Lisps, Clojure's Syntax (programming languages), syntax is built on S-expressions that are first Parsing, parsed into data structures by a Lisp reader before being Compiler, compiled. Clojure's reader supports literal syntax for hash table, maps, sets, and Array (data structure), vectors along with lists, and these are compiled to the mentioned structures directly. Clojure treats Homoiconicity, code as data and has a Lisp macro system. Clojure is a Lisp-1 and is not intended to be code-compatible with other dialects of Lisp, since it uses its own set of data structures incompatible with other Lisps. Clojure advocates immutable object, immutability and persistent data structure, immutable data structures and encourages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leiningen (software)
Leiningen is a build automation and dependency management tool for the simple configuration of software projects written in the Clojure programming language. Leiningen was created by Phil Hagelberg. Phil started the project with the aim of simplifying the complexities of Apache Maven, while offering a way of describing the most common build requirements of Clojure projects in idiomatic Clojure. These aims are succinctly captured in the project's tag line, "Automate Clojure projects without setting your hair on fire". Leiningen's features can be extended via a plugin system, and it is supplied with a command line interface that can initiate a number of actions, which include: * The generation of a simple Clojure project skeleton * Ahead-of-time ( AOT) compilation * Dependency resolution (with automatic library downloading) * Start an interactive REPL that has the classpath correctly set to load project dependencies * Packaging of project code and dependencies into an "uberjar" .j ...

Software Repository
A software repository, or repo for short, is a storage location for Package format, 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 APT (software), Advanced Packaging Tool (APT), commonly found in Debian based distributions, or Yellowdog Up ...

Beta Release
The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. Pre-alpha refers to the early stages of development, when the software is still being designed and built. Alpha testing is the first phase of formal testing, during which the software is tested internally using White-box testing, white-box techniques. Beta testing is the next phase, in which the software is tested by a larger group of users, typically outside of the organization that developed it. The beta phase is focused on reducing impacts on users and may include usability testing. After beta testing, the software may go through one or more release candidate phases, in which it is refined and tested further, before the final version is released. Some software, particularly in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
