Xtext
Xtext is an open-source software framework for developing programming languages and domain-specific languages (DSLs). Unlike standard parser generators, Xtext generates not only a parser, but also a class model for the abstract syntax tree, as well as providing a fully featured, customizable Eclipse-based IDE. Xtext is being developed in the Eclipse Project as part of the Eclipse Modeling Framework Project. It is licensed under the Eclipse Public License. History The first version of Xtext was published in 2006 in the openArchitectureWare project. The last version released under the oAW project was version 4.3. Since the beginning of 2008, Xtext has been developed at Eclipse under the Eclipse Modeling Project.

The framework is mainly developed by the German company Itemis.i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Language Workbench
A language workbench is a tool or set of tools that enables software development in the language-oriented programming software development paradigm. A language workbench will typically include tools to support the definition, reuse and composition of domain-specific languages together with their integrated development environment. Language workbenches were introduced and popularized by Martin Fowler in 2005. Language workbenches usually support: * Specification of the language concepts or metamodel * Specification of the editing environments for the domain-specific language * Specification of the execution semantics, e.g. through interpretation and code generation Examples * Racket is a cross-platform language development workbench including compiler, JIT compiler, IDE and command-line tools designed to accommodate creating both domain-specific languages and completely new languages with facilities to add new notation, constrain constructs, and create IDE tools. * JetBrains ...

Domain-specific Language
A domain-specific language (DSL) is a computer language specialized to a particular application domain. This is in contrast to a general-purpose language (GPL), which is broadly applicable across domains. There are a wide variety of DSLs, ranging from widely used languages for common domains, such as HTML for web pages, down to languages used by only one or a few pieces of software, such as MUSH soft code. DSLs can be further subdivided by the kind of language, and include domain-specific ''markup'' languages, domain-specific ''modeling'' languages (more generally, specification languages), and domain-specific ''programming'' languages. Special-purpose computer languages have always existed in the computer age, but the term "domain-specific language" has become more popular due to the rise of domain-specific modeling. Simpler DSLs, particularly ones used by a single application, are sometimes informally called mini-languages. The line between general-purpose languages and doma ...

Xtend (programming Language)
Xtend is a General-purpose programming language, general-purpose high-level programming language for the Java Virtual Machine. Syntactically and semantically Xtend has its roots in the Java (programming language), Java programming language but focuses on a more concise syntax and some additional functionality such as type inference, extension methods, and operator overloading. Being primarily an object-oriented language, it also integrates features known from functional programming, e.g. Anonymous function, lambda expressions. Xtend is static typing, statically typed and uses Java (programming language), Java's type system without modifications. It is compiled to Java (programming language), Java code and thereby seamlessly integrates with all existing Java libraries. The language Xtend and its IDE is developed as a project at Eclipse (software), Eclipse.org and participates in the annual Eclipse release train. The code is open source under the Eclipse Public License. Yet, the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JetBrains MPS
JetBrains MPS (Meta Programming System) is a language workbench developed by JetBrains. MPS is a tool to design domain-specific languages (DSL). It uses projectional editing which allows users to overcome the limits of language parsers, and build DSL editors, such as ones with tables and diagrams. It supports language-oriented programming. MPS is an environment for language definition, a language workbench, and integrated development environment (IDE) for such languages. Composable languages While domain-specific language extensions can often be useful in general-purpose programming languages, their text-based nature means that adding domain-specific language extensions can lead to ambiguity in text-based syntax. MPS avoids this grammatical ambiguity by working with the abstract syntax tree directly. In order to edit this tree, a text-like projectional editor is used. Because MPS directly uses the abstract syntax tree, MPS supports composable language definitions. This means ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parser Generators
In computer science, a compiler-compiler or compiler generator is a programming tool that creates a parser, interpreter, or compiler from some form of formal description of a programming language and machine. The most common type of compiler-compiler is called a parser generator. It handles only syntactic analysis. A formal description of a language is usually a grammar used as an input to a parser generator. It often resembles Backus–Naur form (BNF), extended Backus–Naur form (EBNF), or has its own syntax. Grammar files describe a syntax of a generated compiler's target programming language and actions that should be taken against its specific constructs. Source code for a parser of the programming language is returned as the parser generator's output. This source code can then be compiled into a parser, which may be either standalone or embedded. The compiled parser then accepts the source code of the target programming language as an input and performs an action or outp ...

Eclipse Modeling Framework
Eclipse Modeling Framework (EMF) is an Eclipse-based modeling framework and code generation facility for building tools and other applications based on a structured data model. From a model specification described in XML Metadata Interchange (XMI), EMF provides tools and runtime support to produce a set of Java classes for the model, a set of adapter classes that enable viewing and command-based editing of the model, and a basic editor. Models can be specified using annotated Java, UML, XML documents, or modeling tools, then imported into EMF. Most important of all, EMF provides the foundation for interoperability with other EMF-based tools and applications. Ecore Ecore is the core (meta-)model at the heart of EMF. It allows expressing other models by leveraging its constructs. Ecore is also its own metamodel (i.e.: Ecore is defined in terms of itself). According to Ed Merks, EMF project lead, "Ecore is the defacto reference implementation of OMG's EMOF" (Essential Meta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Google Guice
Google Guice (pronounced like "juice") is an open-source software framework for the Java platform developed by Bob Lee and Kevin Bourrillion at Google and released under the Apache License The Apache License is a permissive free software license written by the Apache Software Foundation (ASF). It allows users to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of the software .... It provides support for dependency injection using annotations to configure Java objects. Dependency injection is a design pattern whose core principle is to separate behavior from dependency resolution. Guice allows implementation classes to be bound programmatically to an interface, then injected into constructors, methods or fields using an @Inject annotation. When more than one implementation of the same interface is needed, the user can create custom annotations that identify an implementation, then use that annotation when injecting ...

Software Using The Eclipse Public License
Software consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or interpreter to execute on the architecture's hardware. Over time, software has become complex, owing to developments in networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applications # application software, which performs specific tasks for users The rise of cloud ...

Eclipse Foundation
The Eclipse Foundation AISBL is an independent, Europe-based not-for-profit organization that acts as a steward of the Eclipse open source software development community, with legal jurisdiction in the European Union. It is an organization supported by over 350 members, and represents the world's largest sponsored collection of Open Source projects and developers. The Foundation focuses on key services such as intellectual property (IP) management, ecosystem development, and IT infrastructure. Projects The Eclipse Project was originally created by IBM in November 2001 and was supported by a consortium of software vendors. In 2004, the Eclipse Foundation was founded to lead and develop the Eclipse community. It was created to allow a vendor-neutral, open, and transparent community to be established around Eclipse. The Foundation utilizes a hierarchical project structure. Each project stems from a primary parent project and may have sub-projects. The uppermost projects, which do ...

Interpreter (computing)
In computer science, an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program. An interpreter generally uses one of the following strategies for program execution: # Parse the source code and perform its behavior directly; # Translate source code into some efficient intermediate representation or object code and immediately execute that; # Explicitly execute stored precompiled bytecode made by a compiler and matched with the interpreter's virtual machine. Early versions of Lisp programming language and minicomputer and microcomputer BASIC dialects would be examples of the first type. Perl, Raku, Python, MATLAB, and Ruby are examples of the second, while UCSD Pascal is an example of the third type. Source programs are compiled ahead of time and stored as machine independent code, which is then linked at run-ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Code Generation (compiler)
tuo.maxnam computing, code generation is part of the process chain of a compiler, in which an intermediate representation of source code is converted into a form (e.g., machine code) that can be readily executed by the target system. Sophisticated compilers typically perform multiple passes over various intermediate forms. This multi-stage process is used because many algorithms for code optimization are easier to apply one at a time, or because the input to one optimization relies on the completed processing performed by another optimization. This organization also facilitates the creation of a single compiler that can target multiple architectures, as only the last of the code generation stages (the ''backend'') needs to change from target to target. (For more information on compiler design, see Compiler.) The input to the code generator typically consists of a parse tree or an abstract syntax tree. The tree is converted into a linear sequence of instructions, usually in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Virtual Machine
A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform. The JVM reference implementation is developed by the OpenJDK project as open source code and includes a JIT compiler called HotSpot. The commercially supported Java releases available from Oracle are based on the OpenJDK runtime. Eclipse OpenJ9 is another open source JVM for OpenJDK. JVM specification The Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection ...
