Problems solved by technology

[0002] In the process of the development team working together to complete large-scale software, the business requirements in large-scale software are constantly iterated, and the code is also increasing based on business changes, and the code size and complexity are gradually increasing. Due to similar logic code It may appear in different business code components, and it is difficult for the development team to identify codes with similar logic, which will affect the implementation of application scenarios such as code refactoring and business merging

Embodiment Construction

[0033] Such as figure 1 As shown, a method for analyzing source code similarity in the embodiment of the present invention includes the following steps:

[0034] S1. Generate an abstract syntax tree in JSON format according to the program source code;

[0035] S2. Map the abstract syntax tree into a space vector according to the vocabulary in the abstract syntax tree;

[0036] S3. According to the cosine similarity calculation method and the space vector, calculate the cosine similarity used to represent the source code similarity.

[0037] First, generate an abstract syntax tree in JSON format according to the program source code, then map the abstract syntax tree into a space vector according to the vocabulary in the abstract syntax tree, and finally, according to the cosine similarity calculation method and the space vector, calculate the representation The cosine similarity of source code similarity can assist the development team to identify source code with repeated or...

Abstract

The invention relates to a method and system for analyzing source code similarity and electronic equipment. The method comprises the following steps: firstly, generating an abstract syntax tree in a JSON format according to a program source code, mapping the abstract syntax tree into a spatial vector according to vocabularies in the abstract syntax tree; and finally, according to a cosine similarity calculation method and the spatial vector, calculating cosine similarity used for representing source code similarity, thereby assisting a development team to identify repeated or similar logic source codes, and providing a judgment basis for implementation of code reconstruction, service merging and other scenes.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, system and electronic equipment for analyzing source code similarity. Background technique [0002] In the process of the development team working together to complete large-scale software, the business requirements in large-scale software are constantly iterated, and the code is also increasing based on business changes, and the code size and complexity are gradually increasing. Due to similar logic code It may appear in different business code components, and it is difficult for the development team to identify codes with similar logic, which will affect the implementation of application scenarios such as code refactoring and business merging. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method, system and electronic equipment for analyzing the similarity of source codes for the deficiencies of the ...
