The increasing complexity of chemical problems often requiring multiple chemical software work together to complete. Most chemical software uses different script languages to describe jobs, chemists have to consume lots of time to learn them before work. Unified Job-Description Language on Chemical Grid (UDLC) is designed to solve the problem. It is a domain specific-language (DSL), aims at reducing...
The paper develops a Gaussian Syntax-analyzer using ANTLR. The Gaussian Syntax-analyzer is tested by an example, and builds the AST. Then we examine the analysis process of the example through parser tree generated by ANTLRWorks. The Gaussian Syntax-analyzer's design process is helpful for developing analyzer of other chemical software. At the same time, the paper also provides one kind of syntactical...
