Abstract

Methods for forming extensions to scripting language compilers are disclosed. The machine's compiler receives source code with new keywords to the compiler's scripting language. Extends the compiler module processing source code to support new keywords. The compiler and the extended compiler module generate executable machine code based on the progress of the extended compiler module and the compiler.

Description

technical field [0001] This application relates generally to the field of compilers and, in one specific example, to extension mechanisms for compilers. Background technique [0002] Compilers traditionally compile programming languages ​​and transform them into executable code. A compiler performs syntactic and semantic analysis and code generation on a programming language. Compilers can be implemented on the front end or on the back end, and form sophisticated systems for checking the syntax definitions of programming languages. [0003] A programming language consisting of keywords that form the scope of the language. Language itself can be used in different contexts that affect linguistic behavior. However, in some programming languages, new functionality cannot be added by introducing new keywords. Therefore, there is a need to allow different groups to work on the same compiler implementation and to support the use of a programming language in different contexts t...
