Boot (software)
Boot is a build automation and dependency management tool written primarily in the Clojure programming language. Boot was originally written by Micha Niskin and Alan Dipert as part of the Hoplon web framework. As of May 2015, Boot is developed and released independently of Hoplon. Boot is implemented as an executable entry point and a set of Clojure libraries that can be used to develop build processes programmatically. The spirit of Boot's design is captured by its tag line, "Builds are programs. Let's start treating them that way." Build tasks supported natively by Boot include compiling Java (programming language), Java, creating .jar files, and creating Java servlet, servlets. As a Clojure program, Boot can be extended on a per-project basis using the Clojure language. Boot's primary means of extension are ''tasks'', or functions that take and return Filesets. A Fileset is a managed, immutable representation of the filesystem and Classpath (Java), classpath that can be s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages. Java gained popularity sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-platform
Within 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 platform, 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 Interpreter (computing), interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application software, application may run on Linux, macOS and Microsoft Windows. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, ArkUI-X, Kivy (framework), Kivy, Qt (software), Qt, GTK, Flutter (software), Flutter, NativeScript, Xamarin, Apache Cordova, Ionic (mobile app framework ...

Software Development Tools
A programming tool or software development tool is a computer program that is used to develop another computer program, usually by helping the developer manage computer files. For example, a programmer may use a tool called a source code editor to edit source code files, and then a compiler to convert the source code into machine code files. They may also use build tools that automatically package executable program and data files into shareable packages or install kits. A set of tools that are run one after another, with each tool feeding its output to the next one, is called a toolchain. An integrated development environment (IDE) integrates the function of several tools into a single program. Usually, an IDE provides a source code editor as well as other built-in or plug-in tools that help with compiling, debugging, and testing. Whether a program is considered a development tool can be subjective. Some programs, such as the GNU compiler collection, are used exclusively f ...

Eclipse Public License
The Eclipse Public License (EPL) is a free and open source software license most notably used for the Eclipse IDE and other projects by the Eclipse Foundation. It replaces the Common Public License (CPL) and removes certain terms relating to litigations related to patents.In section 7, this sentence is in CPL 1.0, but not EPL 1.0: "If Recipient institutes patent litigation against a Contributor with respect to a patent applicable to software (including a cross-claim or counterclaim in a lawsuit), then any patent licenses granted by that Contributor to such Recipient under this Agreement shall terminate as of the date such litigation is filed." The Eclipse Public License is designed to be a business-friendly free software license, and features weaker copyleft provisions than licenses such as the GNU General Public License (GPL). The receiver of EPL-licensed programs can use, modify, copy and distribute the work and modified versions, in some cases being obligated to release ...

Build Automation
Build automation is the practice of building software systems in a relatively unattended fashion. The build is configured to run with minimized or no software developer interaction and without using a developer's personal computer. Build automation encompasses the act of configuring the build system as well the resulting system itself. Build automation encompasses both sequencing build operations via non-interactive interface tools and running builds on a shared server. Tools Build automation tools allow for sequencing the tasks of building software via a non-interactive interface. Existing tools such as Make can be used via custom configuration file or using the command-line. Custom tools such as shell scripts can also be used, although they become increasingly cumbersome as the codebase grows more complex. Some tools, such as shell scripts, are task-oriented declarative programming. They encode sequences of commands to perform with usually minimal conditional logic. ...

Entry Point
In computer programming, an entry point is the place in a program where the execution of a program begins, and where the program has access to command line arguments. To start a program's execution, the loader or operating system passes control to its entry point. (During booting, the operating system ''itself'' is the program). This marks the transition from load time (and dynamic link time, if present) to run time. For some operating systems and programming languages, the entry point is in a runtime library, a set of support functions for the language. The library code initializes the program and then passes control to the program proper. In other cases, the program may initialize the runtime library itself. In simple systems, execution begins at the first statement, which is common in interpreted languages, simple executable formats, and boot loaders. In other cases, the entry point is at some other known memory address which can be an absolute address or re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Servlet
A Jakarta Servlet, formerly Java Servlet is a Java (programming language), Java software component that extends the capabilities of a server (computing), server. Although servlets can respond to many types of requests, they most commonly implement web containers for hosting web applications on web servers and thus qualify as a server-side servlet web API. Such web servlets are the Java (software platform), Java counterpart to other dynamic web page, dynamic web content technologies such as PHP and ASP.NET. Introduction A Jakarta Servlet is a Java class in Jakarta EE that conforms to the Jakarta Servlet API, a standard for implementing Java classes that respond to requests. Servlets could in principle communicate over any client–server model, client–server protocol, but they are most often used with Hypertext Transfer Protocol, HTTP. In principle, any servlets can extend the class; however, realistically speaking, all servlets extend the class. Thus "servlet" is often u ...

Classpath (Java)
Classpath is a parameter in the Java Virtual Machine or the Java compiler that specifies the location of user-defined classes and packages. The parameter may be set either on the command-line, or through an environment variable. Overview and architecture Similar to the classic dynamic loading behavior, when executing Java programs, the Java Virtual Machine finds and loads classes lazily (it loads the bytecode of a class only when the class is first used). The classpath tells Java where to look in the filesystem for files defining these classes. The virtual machine searches for and loads classes in this order: # bootstrap classes: the classes that are fundamental to the Java Platform (comprising the public classes of the Java Class Library, and the private classes that are necessary for this library to be functional). # extension classes: packages that are in the ''extension'' directory of the Java Runtime Environment or JDK, jre/lib/ext/ # user-defined packages and lib ...

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 ...

Apache Maven
Maven is a build automation tool used primarily for Java projects. Maven can also be used to build and manage projects written in C#, Ruby, Scala, and other languages. The Maven project is hosted by The Apache Software Foundation, where it was formerly part of the Jakarta Project. Maven addresses two aspects of building software: how software is built and its dependencies. Unlike earlier tools like Apache Ant, it uses conventions for the build procedure. Only exceptions need to be specified. An XML file describes the software project being built, its dependencies on other external modules and components, the build order, directories, and required plug-ins. It comes with pre-defined targets for performing certain well-defined tasks such as compilation of code and its packaging. Maven dynamically downloads Java libraries and Maven plug-ins from one or more repositories such as the Maven 2 Central Repository, and stores them in a local cache. This local cache of downloaded arti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classloader
The Java class loader, part of the Java Runtime Environment, dynamically loads Java classes into the Java Virtual Machine. Usually classes are only loaded on demand. The virtual machine will only load the class files required for executing the program. The Java run time system does not need to know about files and file systems as this is delegated to the class loader. A software library is a collection of related object code. In the Java language, libraries are typically packaged in JAR files. Libraries can contain objects of different types. The most important type of object contained in a Jar file is a Java class. A class can be thought of as a named unit of code. The class loader is responsible for locating libraries, reading their contents, and loading the classes contained within the libraries. This loading is typically done "on demand", in that it does not occur until the class is called by the program. A class with a given name can only be loaded once by a given class loade ...
