【摘要】 提出了一种用于单片机测控装置的可裁减的微型脚本语言解释器.为便于控制脚本语言解释器的大小,将脚本语言解释器分解为一组独立的脚本命令解释器模块和一个脚本命令解释器容器.每个脚本命令解释器可以解析和执行一句脚本命令,脚本命令解释器容器则提供一个插件框架将脚本命令解释器模块装配在一起.根据目标测控装置所用到的脚本命令选择所需脚本命令解释器模块,就可以设计出量身定做的微型脚本解释器.为便于概念理解,文中以BA S IC句法的简单脚本语言为例,对脚本命令解释器容器和脚本命令解释器的设计方法进行了介绍.更多还原

【Abstract】 A tiny scalable script interpreter that targets at the MCU based measurement device is proposed.To make the size of the script interpreter controllable,the interpreter is separated into a command parser container and a series of independent command parsers.Each command parser can interpret and execute a script command,and the container has a plug-in framework to assemble independent command parsers.Selecting desired command parsers by the needed script commands of a target measurement device,a tiny script interpreter that just fits the need of application can be built.To expose the concepts,a simple script language of BASIC grammars is taken as an example to show the design procedures of the container and the command parser.更多还原
