Xtext represents an open-source software framework designed for the creation of programming languages and domain-specific languages (DSLs). Differing from traditional parser generators, Xtext produces not just a parser but also a class structure for the abstract syntax tree, complemented by a comprehensive, customizable IDE based on Eclipse.
Originating within the Eclipse Project as a component of the Eclipse Modeling Framework, Xtext is distributed under the terms of the Eclipse Public License.
History
The first version of Xtext was launched in 2006 as part of the openArchitectureWare initiative, concluding with version 4.3 under that project. Since 2008, its development has been maintained under Eclipse’s Modeling Project umbrella.
Xtext follows Eclipse’s yearly coordinated release schedule, with notable editions including 0.7.0 in June 2009, 1.0 in June 2010, 2.0 in June 2011, and continuing through to version 2.7 released in September 2014. The primary development efforts are led by the German firm Itemis.
Functionality
Language designers define grammars using Xtext's own grammar language to outline how an Ecore model corresponds to textual input. This specification results in an ANTLR parser and object model classes that can operate independently of the Eclipse environment.
Xtext offers deep integration with the Eclipse IDE, providing capabilities such as:
- Syntax highlighting
- Code completion suggestions
- Static code analysis
- Outline navigation
- Source code browsing
- Indexing mechanisms
- Side-by-side comparison views
- Hover information displays
- Code folding
- Rename refactoring tools
Through dependency injection and Google Guice, both the framework and IDE components are extensively customizable, allowing straightforward substitution of default modules.
Starting with version 2.0, Xtext facilitates DSL creation targeting the Java virtual machine, supporting compilation into Java artifacts and tight coupling with Eclipse’s Java Development Toolkit. Additionally, a reusable library of expression languages enhances DSL functionalities.
For code generation, Xtext employs an Xtend-based generator that translates DSL elements into Java artifacts to ensure smooth integration with Java projects. Alternatively, an interpreter is available for execution without code generation.
Uses
By April 2016, approximately 40 commercial and non-commercial initiatives across diverse fields were cited on Xtext’s website as users of the framework.
- The widely-used DSL AWK is implemented using Xtext.
- The versatile general-purpose language Xtend is constructed atop Xtext.
