Scripting language execution method and device

Abstract

The embodiment of the invention provides a scripting language execution method, which comprises the following steps: (1) analyzing and explaining the code of a scripting language to generate an operation subset; (2) generating the operation subset into an operable code, and storing the code into a memory; and (3) executing the operable code. The invention also correspondingly provides a scripting language execution device. The scripting language execution method and device carries out a code curing operation on grammatical analysis and operation subset explanation exaction processes in an execution process of the scripting language through a precompiled way, so that the scripting language reduces the explanation exaction process in the execution process, meanwhile, dependence on a virtual machine in the execution process of the scripting language is lowered, and the execution efficiency of the scripting language is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a scripting language execution method and device. Background technique [0002] The execution process of the scripting language depends on the script interpreter. The script interpreter is composed of a lexical analyzer, a syntax analyzer, and an algorithm set. The algorithm set is a part of the scripting language virtual machine and has certain calculation rules built in. The set of language operators analyzed by the syntax analyzer and the final operation result of the script language are obtained. The execution process of a typical script language is as follows: first, the script is analyzed by the lexical analyzer and the syntax analyzer according to predetermined rules, and then the analyzed operator set is Passed to the virtual machine, the virtual machine interprets the operation and obtains the execution result. This typical execution mode causes the script la...

[0002] The execution process of the scripting language depends on the script interpreter. The script interpreter is composed of a lexical analyzer, a syntax analyzer, and an algorithm set. The algorithm set is a part of the scripting language virtual machine and has certain calculation rules built in. The set of language operators analyzed by the syntax analyzer and the final operation result of the script language are obtained. The execution process of a typical script language is as follows: first, the script is analyzed by the lexical analyzer and the syntax analyzer according to predetermined rules, and then the analyzed operator set is Passed to the virtual machine, the virtual machine interprets the operation and obtains the execution result. This typical execution mode causes the script language to go through the process of script parsing and operator parsing during operation, resulting in lower script execution efficiency than compiled languages.

In addition, the execution efficiency of the scripting language is also limited by the execution efficiency of the virtual machine. An inefficient virtual machine or internal algorithm will seriously affect the script running performance
