Estimating the number of coding styles by analyzing source code

A computer system for analyzing a plurality of source code, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• identifying the plurality of source code;
• extracting one or more characteristics from a plurality of lines of the plurality of source code;
• analyzing the one or more extracted characteristics for an inclusion relation and a congruent relation;
• generating a plurality of node relations of a plurality of nodes based on the inclusion relation and the congruent relation, wherein each node within the plurality of nodes corresponds to each line of the plurality of source code;
• determining a sum of the one or more nodes from the plurality of nodes that have no inclusion relation based on the analyzed inclusion relation and the analyzed congruent relation;
• and
• displaying the sum of the determined one or more nodes.

A computer program product for analyzing a plurality of source code, the computer program product comprising:

• one or more computer-readable tangible storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor, the program instructions comprising:
• program instructions to identify the plurality of source code;
• program instructions to extract one or more characteristics from a plurality of lines of the plurality of source code;
• program instructions to analyze the one or more extracted characteristics for an inclusion relation and a congruent relation;
• program instructions to generate a plurality of node relations of a plurality of nodes based on the inclusion relation and the congruent relation, wherein each node within the plurality of nodes corresponds to each line of the plurality of source code;
• program instructions to determine a sum of the one or more nodes from the plurality of nodes that have no inclusion relation based on the analyzed inclusion relation and the analyzed congruent relation;
• and
• program instructions to display the sum of the determined one or more nodes.
