Abstract

PURPOSE:To easily grasp the parts of a program by discriminating an existing program source code from a difference program part. CONSTITUTION:The automatic program forming device consists of a source code forming part 11, a specification control part 12, a program specification data base 13, a parts control 14, an existing program source code data base 15, a difference program part data base 16, and a difference program part forming part 17. After extracting a stored program specification, a difference program part written in the program specification is selected and the existing program source code is corrected based upon the difference program part to form a program source code satisfying the program specification. Thus, a part having no selection branch is previously formed and a part consisting of a changing part is independently formed as the difference program part. Consequently, the contents of the program part are easily grasped.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to program design and development, and in particular to an automatic program generation device and method for generating program source code that satisfies program specifications using program parts, but also to conventional technology in general. In automatic program generation using the generation method (to import program parts, which are units of reuse)
By applying the adaptation rule to this program component, a procedure is taken in which a program source code according to the program specifications is selected from a plurality of program source code candidates.

The conventional method is 1. The source code generation section issues a request to the component management section, analyzes the program component imported from the program component database, and sends a request to the specification management section to create a program that corresponds to the generation rules of the program component. Specifications are retrieved from the program specification database and transferred. Application of generation rules to the previously extracted program parts generates program source code. Problems to be solved by the invention When a new program source code is needed, conventional methods are used. (Yo) I need to modify the program parts so that new program source code can be created. Such modifications become cumbersome as the number of options increases, and the parts become difficult to see.

In order to solve the above problems, the program generation device and method of the present invention (1) first create a component with no options, and then separately create a component with only changed parts as a differential program component, thereby changing the contents of the program component. In order to achieve the above-mentioned object in a distant manner, an automatic program generation device of the present invention (including means for storing program specifications and means for managing the program specifications) is provided. , a means for storing an existing program source code; a means for storing a differential program component that describes the changes when the existing program source code is changed according to program specifications; and the existing program source code and the differential program component. The present invention is configured to include: a means for managing the difference program component; a means for creating the difference program component; a means for automatically generating a new program source code from the program source code, the existing program source code, and the difference program component.

Operation: With the above configuration, the program automatic generation device and method 1 of the present invention extracts the stored program specifications, selects the difference program parts written in the program specifications, and generates the existing program based on the difference program parts. Embodiment 1 shows an embodiment of the automatic program generation device and method of the present invention. 11 indicates the source code. generation i
12 is a specification management unit; 13 is a program specification database; 14 is a component management unit 15 is an existing program source code database;

FIG. 2 is a flowchart showing the processing flow of the embodiment of the present invention.In step 21, the source code generation section 11 issues a request to the specification management section 12, and in step 22, the program specification is extracted.

The program specifications indicate the existing source code numbers used for automatic program generation, and based on this,
In step 23, a request is issued to the component management section 14 to extract the existing program source code.

Next, while there are program specifications for the existing program source code extracted in step 25, the program specifications are extracted. This time, the number of the differential program component is shown, and based on this, in step 26, the source code generation section 11 issues a request to the component management section 14 to extract the differential program component. Furthermore, in step 27, the source code generator 1111 modifies the existing program source code based on the description of the extracted differential program component and generates a program source code that satisfies the program specifications.

The method for creating differential program parts is as follows. The differential program component creation section 17 requests the component management section 14 for existing program source code from which newly required program source code is to be generated. Next, modify the extracted existing program source code.
Create a new program source code. Then, take the difference between the existing program source code and the new program source code and register it as a differential program component in the differential program component database 16. Figure 3 shows how to generate a program using the conventional method. As an example, Fig. 3 32 shows the generated program source code, and Fig. 3 31 shows the third
These are program parts necessary to generate the program source code of FIG. 32.

Assuming that [2] is selected according to the program specifications for the program source code in Fig. 31, Fig. 3
If a program source code like that shown in Figure 3 is generated and a new program source code like that shown in Figure 3 is required, use the conventional method (by replacing the parts in Figure 3 31 with the parts in Figure 3 33). It is necessary to modify it as follows.

FIG. 4 is an example of program generation. FIG. 442 shows the generated program source code, and FIG. 441 shows the generated program source code.
Existing program source code K that is the basis for generating the program source code of 2. Figures 43 to 45 are differential program parts necessary for automatic program generation. , if the differential program part 43 in Figure 4 is left behind due to the program specifications, then Figure 4 42 will be generated.
-, if Figure 4 44 is selected, Figure 3 34 will be generated.
When FIG. 445 is selected, a program source code in which the third line of the existing program source code of FIG. 41 is deleted is generated.

According to the embodiment shown in FIG. 4, there are no marks in the existing program source code, making it easy to understand.1. As described above in detail, according to the present invention, program parts can be easily understood by separating existing program source code and differential program parts.

Ma,? Since the difference program creation section takes the differences, you can create difference program parts without having to worry about which line of the existing source code the description of the difference program part relates to. It's also easy to do.
