Problems solved by technology

[0005] However, when applying methods based on abstract syntax trees, most of them directly use abstract syntax trees, ignoring the further processing of abstract syntax trees, resulting in the data processing methods for tree structures usually requiring more computing resources and time.

Abstract

The invention provides a source code coding sequence representation method based on static program analysis. The source code coding sequence representation method comprises the steps of obtaining a source code text; converting the source code text to obtain an original abstract syntax tree corresponding to the source code text; simplifying the original abstract syntax tree; and performing traversal encoding on the simplified original abstract syntax tree to obtain an encoded sequence representation of the source code text. According to the method, the tree structure of the original abstract syntax tree corresponding to the source code text can be simplified, the tree structure of the original abstract syntax tree can be well converted into the coding sequence, and meanwhile it can be guaranteed that the coding sequence has good retrieval performance and matching performance.

Description

technical field [0001] The invention relates to the technical field of static program analysis of codes, in particular to a source code encoding sequence representation method based on static program analysis. Background technique [0002] In the software industry, an ordered collection of programming languages ​​that can complete a predetermined function is usually regarded as a code segment, so there are a large number of code segments in the software industry. And with the development of the software industry, the rapid increase of private code libraries and open source software projects has further accumulated a large number of code segments that can realize various functions. Therefore, in the current software development, the effective reuse of existing code segments, Has become a fast and efficient software development activity. How to find existing code segments that meet the needs of developers from the existing code base, and accelerate the software development pr...
