In recent years, as a method to improve the language performance of scripting languages has attracted the attention of the Just-In-Time (JIT) compilation techniques for scripting language. The difficulty of JIT compilation for scripting language is its dynamically typed code and in its own language runtime. The purpose of this paper is to evaluate the performance overhead of JIT compilation of runtime library's overhead by using a statically typed scripting language. In this study, we use a statically typed scripting language KonohaScript to analyze language runtime performance impact of the code generated by the JIT compiler.

Parsing Expression Grammars are a popular foundation for describing syntax. Unfortunately, several syntax of programming languages are still hard to recognize with pure PEGs. Notorious cases appears: typedef-defined names in C/C++, indentation-based code layout in Python, and HERE document in many scripting languages. To recognize such PEG-hard syntax, we have addressed a declarative extension to PEGs. The “declarative” extension means no programmed semantic actions, which are traditionally used to realize the extended parsing behavior. Nez is our extended PEG language, including symbol tables and conditional parsing. This paper demonstrates that the use of Nez Extensions can realize many practical programming languages, such as C, C#, Ruby, and Python, which involve PEG-hard syntax.
