Description

  The present invention relates to a program development support system, method, and program for supporting a development tool for developing a program using a standard library and a business library.

  In development tools that develop programs using the standard library and business library, the development support function when using functions (parts) in the program coding of the development target program is a cursor from the front space when inputting information about the function. This is realized by a method of acquiring information up to the position and displaying a matching function (part name) in the forward matching search.

  For example, when inputting a function (part) such as printf (), if a part of the function (for example, pri) is input in the source editor, a forward matching search is performed in a pop-up window, and a candidate character string (printf ()) Is displayed. Then, one to be used is selected from the displayed candidate character strings.

Here, not only source programs and documents, but also information related to program development, such as the person in charge and tools used in projects, is managed as a unit of resources in a certain format, and each piece of information has a logical meaning. There is one in which data is managed in a unified manner by using this associated information (see, for example, Patent Document 1).
JP-A-9-212352

  However, although the thing of patent document 1 can create a program and the efficiency of program development improves without a user being conscious of the relation between each information at all, the function which can be referred from a source editor is displayed and development support is performed. It is not a thing.

  Functions that support development by displaying functions that can be referenced from the source editor are uniquely categorized by "function name", so if any part of the specification is different, it becomes a "separate function" and similar functions. It is difficult to find the function of

  Therefore, in the prior art, the “function” cannot be used unless the “function name” is known, and it is difficult to reuse the “function”. That is, when a new function is created by modifying the “function”, it is difficult to make the new function name known for reuse. Also, if there are various types of functions, the features for each function are not displayed when selecting “Function”, so it is difficult to reuse. Also, if a similar (derived) program is created, change points etc. are registered. It is difficult to reuse because it cannot.

  Furthermore, since the search is performed using the “function name” as a key, the search is not performed by function (attribute) but by name, and it is difficult to search for a derived program. For this reason, even if a check function or the like is created for a business program, it is difficult to make it known to the user, and the created function is not effectively used.

  Thus, the conventional development support function (input support function) cannot be used without knowing the “function name” even if there is an existing function. Further, in the conventional function (part) management, functions (parts) that can be referred to from the source editor are managed by name and are not categorized in terms of function, so that reuse is not promoted.

  For example, a well-known function obtained by partially modifying the function “A” is given another name, for example, B. The relationship between “A” and “B” cannot be registered and managed. For this reason, reuse of “B”, which is a derived function created as necessary, is not promoted.

  An object of the present invention is to provide a program development support system, method, and program that can manage functions that occur in various ways and can easily reuse functions without knowing the function name.

The program development support system according to the present invention includes a function master database pre-stored with attributes assigned to functions of the business library of a development tool for developing a program using a standard library and a business library, and developed with the development tool. A variable master database pre-stored with attributes assigned to variables used in the development target program, variable extraction means for searching and extracting variables described in one sentence in software coding of the development target program, and the variable extraction A function group display output means for extracting the attribute of the variable extracted by the means from the variable master database, extracting the function group related by the attribute from the function master database, and displaying the function group on the development tool. And

The program development support method according to the present invention includes a function master database pre-stored with attributes assigned to functions of the business library of a development tool for developing a program using a standard library and a business library, and developed with the development tool. A program development support method by a computer having a variable master database pre-stored with attributes assigned to variables used in a development target program to be searched for a variable described in one sentence in software coding of the development target program The attribute of the extracted variable is extracted from the variable master database, and a function group associated with the attribute is extracted and displayed on the development tool.

The program development support program according to the present invention is a function master database pre-stored with attributes assigned to functions of the business library of a development tool for developing a program using a standard library and a business library, and developed by the development tool. A procedure for searching and extracting a variable described in one sentence in software coding of the development target program in a computer having a variable master database pre-stored with attributes used for variables used in the development target program; A procedure for extracting the attribute of the extracted variable from the variable master database, extracting a function group related by the attribute from the function master database, and displaying the function group on the development tool is executed.

  According to the present invention, functions that occur in various ways can be managed and functions can be easily reused without knowing the function name. In addition, since the existing function can be modified and the created derivative program can be registered as one of the variations, the selection range when using the function can be expanded, and the reuse of the function can be promoted.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a program development support system according to an embodiment of the present invention. The program development support system 11 provides program development support for a development tool 12 that develops a program. The development tool 12 develops a program by the program creation means 15 using the standard library 13 and the business library 14. The standard library 13 stores a standard language used for developing a program, for example, a standard function in C language, and the business library 14 is used for program coding of the development target program. Various business functions different from the standard library 13 are stored.

The program developer inputs information necessary for program development from the input device 16, accesses the program creation means 15, and creates a program according to the information displayed on the display device 17.

  On the other hand, the program development support system 11 supports development when a program is developed with the development tool 12, and has three databases: a function master database 18, a variable master database 19, and a usage history database 20. The search engine 21 searches for an appropriate function necessary for creating the program and provides it to the development tool 12. The search engine 21 includes variable extraction means 22 and function group display output means 23. In addition, function creating means 24 for creating a new function is provided.

  The variable master database 19 is a master in which variables to be used in the development target program are defined in advance, and information in which attributes are assigned to the variables used in the development target program developed by the development tool 12 is stored in advance. . When it is assumed that the development tool 12 creates a program for a specific industry / business, variables to be used can be defined in advance. For example, in the case of contract information for insurance companies, the items described in the contract are set as variable items. Organize this variable with attributes. That is, the variable master database 19 stores data having a table structure (variable name, attribute).

  The function master database 18 is a master for associating variables (attributes) and functions (components), and stores information in which attributes are assigned to functions in the business library. That is, the function master database 18 stores data having a table structure (attribute, function name). The usage history database 20 holds the number of programs used for each variable as a usage history.

  The variable extraction unit 22 of the search engine 21 searches for a variable described in one sentence in the software coding of the development target program received from the program creation unit 15 of the development tool 12. The data is output to the group display output means 23. The function group display output unit 23 extracts the attribute of the variable extracted by the variable extraction unit 22 from the variable master database 19, extracts the function group related to the attribute from the function master database 18, and displays the display device of the development tool 12. 17 is displayed and output. Further, the function group display output means 23 displays the function candidate display order based on the number of uses of the use history in the use history database 20.

  The function creating means 24 creates a new function and has a program addition function and a program update / deletion function. The program addition function is registered as a new program when a new function is created, and is registered as a new program even when an existing function is “updated / changed”. Change points are registered when a new function is registered. The change point is entered to identify various derived programs, and the change point is briefly described. The program update / deletion function has a rule that the program is corrected and deleted, and overwriting is not basically performed except for the problem correction of the program. Even in the case of deletion, a change is made from the update program.

  The variable master update program 25 performs variable registration and variable registration check. The variable registration is for registering the variable name used in the development tool 12 in the variable master database 19, and the variable registration check is for checking the fluctuation of the variable notation. Further, the usage history update program 26 manages the function usage history for each variable. In this case, function candidate display on the function group display output means 23 is in order of increasing usage history.

  Next, the association between the variable master and the function master is performed using “attributes”. Include variables and functions that have many-to-many relationships. The association of the variable A and the function B with the attribute is basically as follows.

Variable A → (Pegging) → Function B
When the variable name “A” is designated, the function B is displayed as a candidate of an available function. In this case, the function can be used without knowing the function name because the function is searched by extracting the “variable name” in the input line instead of the forward matching search of the input data. Function use (activation) is activated by a shortcut key or the like.

  Further, as an auxiliary function for function reuse, it is possible to display a summary of a function when displaying a candidate function. Also, another function can be created by changing the original function. The created function is saved as a separate function (derived program) without being overwritten on the original function, and an input of a change point with respect to the original function is an essential item. In addition, a many-to-many relationship is established in order to provide flexibility in associating variables with functions.

  In order to create a many-to-many relationship, the database is divided into two types: variable master database {table structure (variable name, attribute)} and function master database {table structure (attribute, function name)}. Make the following associations: FIG. 2 is an explanatory diagram of an example of the relationship between the variable master of the variable master database 19 and the function master of the function master database 18.

  Here, some variables called date have dates and numbers as attributes, those that have dates as attributes have date1 () and date2 () as functions, and those that have numbers as attributes have numeric as a function. () Is tied. Therefore, the date variable (date1), date2 (), and numeric () are linked to the variable date, and the function master is searched for using the attributes (date, number) of the variable date. Similarly, two types of functions date1 () and date2 () are linked to the birthday variable, and the function master is searched with the attribute (date) of the variable birthday.

  When the variable master and the function master are related as shown in FIG. 3, two of date_check () and nengo () are selected for the variable birthday and displayed on the display device.

  As described above, it has a display priority function, and performs display priority management according to the function usage frequency. The display order of candidate functions is assumed to be frequently used. In addition, in order to increase the degree of freedom of use of functions, an API (Application Programming Interface) is prepared and an API is prepared for calling functions.

  FIG. 4 is a flowchart showing the processing contents of the program development support method according to the embodiment of the present invention. First, a variable included in one sentence input from the development tool 12 is extracted by the variable extraction means 22 (S1), and a function group applicable based on the attribute of the extracted variable is displayed by the function group display output means 23 by the display device 17. (S2). Then, it is determined whether there is a function to be incorporated in the displayed function group (S3). If there is a function to be incorporated, the function is selected via the input device 17 (S4), and the selected concerned function is selected. The function is incorporated into the development target program by the program creation means 15 (S5).

  On the other hand, if it is determined in step S3 that there is no function to be incorporated, a function to be incorporated is newly created by the function creating means 24 (S6), and the created new function is incorporated into the development target program (S7). Then, it is determined whether or not the created new function is a change of the existing function (S8). If the new function is not a change of the existing function, an attribute is added and stored in the function master database 18 with an alias (S9). . On the other hand, when the new function is a change of an existing function, the created new function is given the same attribute as the original function and stored in the function master database 18 with an alias (S10). In the above description, the new function is created after the step S3. However, the new function may be created in advance before the step S1.

  According to the embodiment of the present invention, since a function (part) is searched from a variable name, the function can be reused without knowing the function name, and the reuse of the function is promoted. In addition, by modifying an existing function and registering the created derivative program as one of the variations, the selection range when using the function can be expanded.

  Note that the method described in the above-described embodiment can be stored in a storage medium as a program that can be executed by a computer and applied to each device, or transmitted through a communication medium and applied to various devices. is there. As a storage medium in the present invention, a magnetic disk, a flexible disk, an optical disk (CD-ROM, CD-R, DVD, etc.), a magneto-optical disk (MO, etc.), a semiconductor memory, etc. can be stored and can be read by a computer. As long as it is a simple storage medium, the storage format may be any form. Here, the storage medium is not limited to a medium independent of the computer, but also includes a storage medium in which a program transmitted via a LAN or the Internet is downloaded and stored or temporarily stored.
