Code reading supporting device, code reading supporting method, and storage medium

A code reading supporting method for supporting decipher of a source code, comprising:

• acquiring information on a plurality of functions described in the source code, a calling relationship between the plurality of functions, and code blocks indicative of control structures in the respective plurality of functions;
• specifying the code block decipher by the user as the already read code block by input of the user;
• generating an already read graph expressing an already read function including the already read code block, of the plurality of functions, all the code blocks included in the already read function, and a calling relationship between the already read code block and the already read function,
• wherein
• an expression of the already read code block differs from an expression of the other code block, of all the code blocks displayed in the already read graph.

A non-transitory computer-readable storage medium having stored thereon a code reading supporting program for supporting decipher of a source code which is executable by a computer, the code reading supporting program comprising instructions capable of causing the computer to execute functions of:

• acquiring information on a plurality of functions described in the source code, a calling relationship between the plurality of functions, and code blocks indicative of control structures in the respective plurality of functions;
• specifying the code block decipher by the user as the already read code block by input of the user;
• generating an already read graph expressing an already read function including the already read code block, of the plurality of functions, all the code blocks included in the already read function, and a calling relationship between the already read code block and the already read function,
• wherein
• an expression of the already read code block differs from an expression of the other code block, of all the code blocks displayed in the already read graph.
