Embodiment Construction

[0021] As mentioned in the background technology, the comparison of program texts in the prior art is to judge whether two program texts are the same through the method of text comparison, and it is impossible to accurately judge two programs that differ in text content but are identical in program structure The text is the same. In order to solve the defects of the prior art, this application proposes a method for comparing program texts, which includes: analyzing and comparing two program texts based on the program structure; if the comparison results are the same, then determine whether the two programs The texts are the same; if the comparison results are different, it is determined that the two program texts are different.

[0022] The embodiment of the present application provides a method for comparing program texts, such as figure 1 shown, including the following steps:

[0023] Step S101, analyzing the two program texts based on the program structure to obtain corre...

Abstract

The embodiment of the invention discloses a method and equipment for comparing program texts. The method comprises the steps of: performing program structure analysis on a first program text and a second program text to obtain first program structure description information and second program structure description information; comparing the first program structure description information with the second program structure description information; if the comparison results of the first program structure description information and the second program structure description information are the same, determining that the first program text is the same as the second program text; and if the comparison results are different, determining that the first program text is different from the second program text. By the technical scheme, the program texts with different text contents and same program structure can be judged; the intelligence and accuracy of comparing the program texts are improved; and the program development and management efficiency is increased.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for comparing program texts. Background technique [0002] The version management system is a system used to manage the change records of documents, program texts, and other computer file information. It is suitable for software development occasions where multiple people modify the same file. Each change to a managed file is called a version, and each version has a timestamp and a committer corresponding to it. Changes to files can be used for comparison, reversion, and even merging. [0003] When managing source code, the corresponding version management system is a source code management system. Current source code management systems, such as svn (subversion), usually use a text comparison method to compare program texts. Specifically, the method of character matching is used to compare the text of the two program texts, and the substrings are...
