Xtext-based software engineering design method of domain specific language (DSL)

Abstract

The invention discloses a Xtext-based software engineering design method of a domain specific language (DSL). The method comprises: step 1, converting an EMF meta-model to an Xtext semantics model; step 2, using a topology graph structure to validate and optimize the semantics model according to the initial DSL semantics model obtained in step 1; step 3, utilizing a method of editing validation rules at a syntax validation module of Xtext to validate code; and step 4, generating C / Java code after validation is completed. According to the Xtext-based software engineering design method of the domain specific language of the invention, a DSL design process is regulated, and DSL construction costs are reduced; at the same time, relevant personnel are helped to debug the code on the basis of the code validation module of the Xtext, and the adaptability of the DSL to a software environment is enhanced; and finally, the DSL code is enabled to be used to automatically generate the C / Java code, and language noise and language concentration camp problems are avoided.

Description

technical field [0001] The invention relates to a software engineering project technology, in particular to an Xtext-based software engineering design method. Background technique [0002] Nowadays, in the process of software development, with the increasing scale and complexity of software development, different fields rely on the development of software systems, realizing the transformation from mechanization to informatization. As an important method in the field of system engineering engineering, Domain Specific Language (DSL) is famous for its high development efficiency, low communication cost, high abstraction and high reusability in specific domain engineering projects. In new software engineering projects, more and more DSLs are used. [0003] Based on the existing DSL design scheme, the construction cost of the DSL is too high due to the limitations of the design process and methods. And because of the irregularity of DSL customization, a large number of good and...

Problems solved by technology

[0003] Based on the existing DSL design scheme, due to the limitations of the design process and methods, the construction cost of DSL is too high

And because of the irregularity of DSL customization, a large number of good and bad DSLs have been born, which also makes the language noise problem serious.

Finally, because the scope of application of DSL is too narrow, a small change in the software environment may cause the failure of DSL, which makes the excellent DSL overused and falls into a language concentration camp crisis.
