Problems solved by technology

[0004] However, the accuracy rate of this program code conversion scheme in the prior art is low, and program developers are required to perform lexical analysis and syntax analysis for the program language to be converted and the target program language
Therefore, this solution can only be used to convert simple codes at present, and cannot be widely used

Abstract

The invention discloses an automatic code conversion method, an automatic code conversion device, a code converter and a medium. The code conversion method comprises the following steps: constructingan abstract syntax tree corresponding to a semantic module of a source code from the source code by using a compiler; for a corresponding abstract syntax tree of one semantic module, obtaining syntaxexpression of the abstract syntax tree; and based on the obtained syntax expression of the corresponding abstract syntax tree of one semantic module, generating a corresponding target code semantic module from the abstract syntax tree according to a predetermined conversion rule between the syntax expression of the abstract syntax tree and the target code. According to the method, the abstract syntax tree is constructed for the source code by using the compiler. The target code is generated based on the constructed abstract syntax tree, so that automatic conversion of the program code is realized.

Description

technical field [0001] The invention relates to program code conversion technology, in particular to a code automatic conversion method and device, a code converter and a medium. Background technique [0002] In the industry, the demand for automatic program code conversion has always been great, but there is no widely used automatic program code conversion solution. [0003] Usually, the solution to realize program code conversion is: first treat the program code as ordinary text, conduct regular analysis, and identify language symbols such as "[]", ";", "{}" in it to determine that the text content is a statement It still has semantics such as function calls; then, through specific rules, the corresponding target language program code is generated. [0004] However, the accuracy rate of this program code conversion solution in the prior art is low, and program developers are required to perform lexical analysis and syntax analysis on both the program language to be conver...
