Description

  The present invention relates to a method for producing a program for producing a new source program for operating in an other environment from an old source program operating in an environment.

  Conventionally, as a technique for automatically converting source programs and scripts, there has been a technique for automatically detecting differences in descriptions caused by compiler differences and automatically correcting or listing them to improve development work (see Patent Document 1). This technology parses a source program written in C language, creates a database and an intermediate file for each token, deletes / changes the target character string on the database, and stores information on the database and the intermediate file. The program is generated in a C language file and a target program is generated.

As a second conventional technique, there is a technique for automatically generating software that can be executed on another computer based on a program object developed on a specific computer (see Patent Document 2). In the present technology, an object code executable under a given computer resource is divided into an instruction code area D2 and a data code area D3 by a segment divider. Subsequently, the instruction code area D2 is converted into an instruction statement in a high-level program language by analyzing an instruction set and an OS primitive by an instruction code converter. In the data code area D3, a data type corresponding to the type of the instruction code being referred to is determined, and is converted into a data definition sentence in a high-level program language by the data syntax converter. Further, the reference area converter adds a reference name to be used by the command statement to the data definition statement, and converts the command statement into a format using the reference name to generate a high-level language program. .

  However, it is considered that the technique disclosed in Patent Document 1 is based on the premise that all instructions included in the specification of the program language in which the source program to be converted is described are automatically converted. In addition, it is considered that the technique disclosed in Patent Document 2 is based on the premise that all program objects on a specific computer are automatically converted. That is, in the prior art, in order to shift the operating environment of one program, it is not considered to efficiently operate the one program in the environment after the migration. Therefore, in the prior art, it is impossible to determine which instruction pattern of the source program to be converted is automatically converted and which instruction pattern is manually performed. In the prior art, when developing an automatic conversion program that automatically or semi-automatically converts a single program, it is impossible to determine which instruction pattern should be developed. A new quality source program could not be produced. Specifically, the prior art is premised on developing a program that automatically converts an instruction pattern that appears only once in a program to be converted.

  In order to solve the above problem, one or more pairs of first instruction pattern information, which is information indicating an instruction pattern of an old source program, and second instruction pattern information, which is information indicating an instruction pattern of a new source program, are stored in a storage unit And an analysis step for analyzing how many times the one or more first command pattern information appears in the old source program using an analysis means, and an analysis result in the analysis step as an output means. The analysis result output step used for output corresponds to the first command pattern information analyzed that the number of appearances of the first command pattern information is a predetermined number of times (the predetermined number is 2 or more) in the analysis step. Use conversion means so that the description part of the old source program corresponds to the second instruction pattern information paired with the first instruction pattern information. An instruction pattern converting step for converting the old source program in the instruction pattern converting step, a new program output step for outputting using the output means, and a first instruction in the analyzing step. With respect to the description portion of the old source program corresponding to the first command pattern information analyzed that the number of occurrences of the pattern information is less than the predetermined number of times, the description portion of the old source program is manually replaced by the new source program. The method of producing a new source program for operating in another environment from an old source program operating in one environment, comprising the step of accepting input using an input means A source program with fewer defects can be produced. The source program production method is a program production method for efficiently producing a high-quality new source program for operating in a new environment from an old source program operating in the old environment.

In addition, one or more pairs of first instruction pattern information, which is information indicating the instruction pattern of the old source program, and second instruction pattern information, which is information indicating the instruction pattern of the new source program, are stored. An analysis unit that analyzes how many times the one or more first command pattern information appears in the old source program, an analysis result output unit that outputs an analysis result in the analysis unit, and The description location of the old source program corresponding to the first instruction pattern information analyzed that the number of appearances of one instruction pattern information is equal to or greater than a predetermined number (the predetermined number is 2 or more) is the first instruction pattern information. An instruction pattern conversion unit for converting the second instruction pattern information to be paired, and the old source program in the instruction pattern conversion unit; A new program output unit that outputs a new source program that is a result of converting the ram, and the first command pattern information analyzed by the analysis unit that the number of occurrences of the first command pattern information is less than the predetermined number of times An old source program that was operating in a certain environment, having an input receiving unit that accepts an input for changing the description portion of the old source program to the new source program manually by the user with respect to the description portion of the old source program This is a production device for a program that produces a new source program to be operated in another environment.

  FIG. 1 shows a block diagram of the program analysis apparatus. The program analysis apparatus includes an instruction pattern information storage unit 101, a program storage unit 102, an analysis unit 103, and an analysis result output unit 104. The program analysis device is, for example, a personal computer that includes an MPU, a memory, a hard disk, and the like.

  The instruction pattern information storage unit 101 stores one or more instruction pattern information that is information indicating an instruction pattern of a program. The command pattern information storage unit 101 can be realized by a non-volatile recording medium or a volatile recording medium.

  The program storage unit 102 stores a program. The program storage unit 102 can be realized by a non-volatile recording medium or a volatile recording medium. A program is a source program, and its language is not limited. The program includes HTML, XML, etc., which are so-called scripts. The program may be a procedural program, a declarative program, or the like, and the program includes a data group (header file or the like) for operating the program.

  The analysis unit 103 analyzes how many times one or more instruction pattern information appears in the program stored in the program storage unit 102. The analysis unit 103 can usually be realized by an MPU, a memory, or the like. The processing procedure for analysis by the analysis unit 103 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

The analysis result output unit 104 outputs the analysis result in the analysis unit 103. Output usually means display on a display, but includes printing on a printer, transmission to another apparatus, and the like. The output is a concept including accumulation in a recording medium such as a hard disk. Further, the analysis result output unit 104 may be considered as including or not including an output display or a recording medium. The analysis result output unit 104 can be realized by, for example, driver software for an output device.
The operation of the program analysis apparatus will be described below using the flowchart of FIG.

(Step S <b> 201) The analysis unit 103 reads a program in the program storage unit 102. This program is a program to be analyzed. When a plurality of programs are stored in the program storage unit 102, for example, the analysis unit 103 reads a program instructed by the user.
(Step S202) The analysis unit 103 reads one or more command pattern information stored in the command pattern information storage unit 101.

  (Step S203) The analysis unit 103 sets all the command pattern appearance counts, which are the command pattern information appearance counts, to zero. Note that the number of command pattern appearances corresponding to all command pattern information is stored in, for example, a memory held by the analysis unit 103.

  (Step S204) The analysis unit 103 substitutes 1 for a counter i. This counter is a program counter of the program read in step S201. That is, the analysis unit 103 analyzes the i-th line of the program read in step S201 by the following process. Here, it is assumed that the program is a program with one instruction pattern per line.

  (Step S205) The analysis unit 103 determines whether or not the i-th program source line exists in the program read in step S201. If the i-th program source line exists, the process goes to step S206, and if the i-th program source line does not exist, the process jumps to step S213.

  (Step S206) The analysis unit 103 substitutes 1 for a counter j. The counter j is a counter for acquiring command pattern information used for analysis among the one or more command pattern information read in step S202.

(Step S207) The analysis unit 103 determines whether or not the i-th program source line is an instruction pattern line corresponding to the j-th instruction pattern information. If the i-th program source line is the j-th instruction pattern, the process goes to step S208. Whether or not the i-th program source line corresponds to the j-th instruction pattern information can be determined by syntax analysis, lexical analysis, or the like, and is an existing technology, and thus detailed description thereof is omitted here.
(Step S208) The analysis unit 103 increments the instruction pattern appearance count corresponding to the j-th instruction pattern information by one.
(Step S209) The analysis unit 103 increments i. The process returns to step S205.
(Step S210) The analysis unit 103 increments j.

(Step S211) The analysis unit 103 determines whether or not the j-th command pattern exists in the command pattern information storage unit 101. If the jth instruction pattern exists, the process returns to step S207, and if the jth instruction pattern does not exist, the process goes to step S212.
(Step S212) The analysis unit 103 outputs an error message “not applicable to any command pattern”. However, this error output process may not be performed.
(Step S213) The analysis result output unit 104 outputs an analysis result. The analysis result is the number of times an instruction pattern appears in each instruction pattern information.

  Hereinafter, specific operations of the program analysis apparatus and the like in the present embodiment will be described. FIG. 3 is an instruction pattern information management table held by the instruction pattern information storage unit 101. The command pattern information management table stores a plurality of records having “ID” and “command pattern information”. “ID” is information for identifying a record, and is information used for table management. “Instruction pattern information” is an attribute for storing instruction pattern information.

  FIG. 4 is a command pattern appearance count management table held by the analysis unit 103. The command pattern appearance count management table has one or more records having “ID” and “appearance count”. “ID” corresponds to “ID” in the command pattern information management table of FIG. “Number of appearances” indicates the number of appearances of the command pattern. The initial values of “number of appearances” are all “0”.

  FIG. 5 is an example of a program stored in the program storage unit 102. The program analysis apparatus starts analyzing the program shown in FIG. 5 according to a user instruction. In the program of FIG. 5, the line starting with “*” is a comment line. Note that the program analysis apparatus does not perform analysis after determining that the line is a comment line.

  The analysis unit 103 first reads the first line of the program in FIG. Since the first line is a comment line, the next line is advanced (the program counter is advanced). The analysis unit 103 does not perform analysis because the second to eighth lines are also comment lines.

  Next, the analysis unit 103 reads “IDENTIFICATION DIVISION.” On the ninth line of the program. The analysis unit 103 determines that the ninth line of the program corresponds to the instruction pattern information of “ID = 1” in the instruction pattern information management table of FIG. Then, the analysis unit 103 increments the value of “number of appearances” in the record of “ID” = “1” in the command pattern appearance number management table of FIG. The result is the command pattern appearance count management table of FIG.

Next, the analysis unit 103 reads “PROGRAM-ID. PSD712” on the 10th line of the program. The analysis unit 103 determines that the 10th line of the program corresponds to the instruction pattern information of “ID = 2” in the instruction pattern information management table of FIG. Note that “variable 01”, “variable 02”, and the like in the instruction pattern information management table of FIG. 3 mean variables. In the program, the variable is composed of an alphanumeric character string. Here, “PSD712” is a variable. Then, the analysis unit 103 increments the value of “number of appearances” of “ID” = “2” in the command pattern appearance number management table of FIG.
The above processing is performed for all the lines of the program shown in FIG. Then, the command pattern appearance count management table shown in FIG. 7 is obtained.

  Next, the analysis result output unit 104 outputs an analysis result as shown in FIG. The analysis result has “ID”, “number of times”, and “command pattern”. “Number of times” is the number of appearances. 8 includes the instruction pattern information management table of FIG. 3 and the instruction pattern appearance count management table of FIG. Specifically, the analysis result of FIG. 8 is a result obtained by performing a join operation using “ID” of the instruction pattern information management table of FIG. 3 and the instruction pattern appearance count management table “ID” of FIG. It is.

  As described above, according to this embodiment, it is possible to analyze an instruction pattern included in a source program to be converted, and as a result, an automatic conversion program that efficiently converts the source program can be developed. The process of automatically converting a program in response to the analysis result in the present embodiment will be described in the second and subsequent embodiments.

  In the present embodiment, an instruction pattern in which a certain number of times or more appears may be visually distinguished from other instruction patterns. In such a case, for example, an analysis result as shown in FIG. 9 is displayed. According to FIG. 9, an instruction pattern that appears three or more times is visually distinguished from other instruction patterns. Note that an aspect in which an instruction pattern that appears a certain number of times or more is visually distinguished from other instruction patterns and displayed is not limited to the aspect in FIG. 9 and may be anything.

  The operations described in this embodiment may be realized by a computer-readable program. The program may be recorded and distributed on a recording medium such as a CD-ROM, may be distributed by network distribution, or may be distributed by broadcasting. This also applies to other embodiments. Note that a program that realizes the operation described in the present embodiment stores one or more instruction pattern information, which is information indicating an instruction pattern of the program, in the computer. What is the one or more instruction pattern information in the program? This is a program for executing an analysis step for analyzing whether or not it appears once and an analysis result output step for outputting an analysis result in the analysis step.

Furthermore, in the present embodiment, the program is analyzed by one program analysis device, but the processing may be shared by a plurality of devices. That is, one or more instruction pattern information, which is information indicating the instruction pattern of the program, is stored, an analysis step for analyzing how many times the one or more instruction pattern information appears in the program, and an analysis result in the analysis step If the program can be analyzed using one or more apparatuses by the program analysis method including the output analysis result output step, the above-described effects can be obtained.
(Embodiment 2)

  FIG. 10 is a block diagram of the automatic program conversion apparatus. The automatic program conversion apparatus includes an instruction pattern correspondence information storage unit 1001, a program storage unit 102, an analysis unit 103, a condition storage unit 1002, an instruction pattern conversion unit 1003, and a new program output unit 1004. The automatic program conversion device is, for example, a personal computer including an MPU, a memory, a hard disk, and the like.

  The instruction pattern correspondence information storage unit 1001 includes first instruction pattern information that is information indicating an instruction pattern of an old program (conversion target program) and second instruction that is information indicating an instruction pattern of a new program (converted program). One or more pairs of pattern information are stored. The instruction pattern correspondence information storage unit 1001 can be realized by a non-volatile recording medium or a volatile recording medium.

  The condition storage unit 1002 stores a condition for automatically converting a part of the old program corresponding to the first command pattern information so as to correspond to the second command pattern information. The condition storage unit 1002 can be realized by a non-volatile recording medium or a volatile recording medium. The condition is often embedded in a program that implements the processing performed by the instruction pattern conversion unit 1003 (including the case defined in the header file). The conditions are conditions based on the analysis result of the analysis unit 103.

  The instruction pattern conversion unit 1003 is one of the old programs corresponding to the first command pattern information that matches the condition stored in the condition storage unit 1002 with respect to the program (old program) stored in the program storage unit 102. The section is converted so as to correspond to the second command pattern information paired with the first command pattern information. The command pattern conversion unit 1003 can usually be realized by an MPU, a memory, or the like. The processing procedure for the command pattern conversion unit 1003 to convert information is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

The new program output unit 1004 outputs a new program that is the result of the instruction pattern conversion unit 1003 converting the program. Output usually means display on a display, but includes printing on a printer, transmission to another apparatus, storage on a recording medium (hard disk, digital multipurpose disk, etc.), and the like. Further, the new program output unit 1004 may be considered as including or not including an output display or a recording medium. The new program output unit 1004 can be realized by output device driver software, for example.
Hereinafter, the operation of the automatic program conversion apparatus will be described with reference to the flowchart of FIG.

  (Step S1101) A program analysis routine is executed. This program analysis routine is the program analysis process described with reference to the flowchart of FIG. 2, and outputs the number of appearances for each instruction pattern in the old program that is the program to be converted.

(Step S1102) The instruction pattern conversion unit 1003 reads the program in the program storage unit 102. When there are two or more programs in the program storage unit 102, for example, the command pattern conversion unit 1003 reads a program instructed by the user.
(Step S1103) The command pattern conversion unit 1003 reads one or more first command pattern information held by the command pattern correspondence information storage unit 1001.

  (Step S1104) The instruction pattern conversion unit 1003 substitutes 1 for the counter i. This counter is a program counter of the program read in step S1102. That is, the instruction pattern conversion unit 1003 converts the i-th line of the program read in step S1102 by the following process. Here, it is assumed that the program is a program with one instruction pattern per line.

  (Step S1105) The instruction pattern conversion unit 1003 determines whether or not the i-th line program source exists in the program read in step S1102. If the i-th program source exists, the process goes to step S1106, and if the i-th program source does not exist, the process jumps to step S1116.

  (Step S1106) The instruction pattern conversion unit 1003 substitutes 1 for a counter j. The counter j is a counter for acquiring first command pattern information used for conversion among the one or more first command pattern information read in step S1103.

  (Step S1107) The instruction pattern conversion unit 1003 determines whether or not the i-th program source corresponds to the j-th first instruction pattern information. If it corresponds to the j-th first command pattern information, the process goes to Step S1108, and if it does not correspond to the j-th first command pattern information, the process jumps to Step S1113. Whether the program source on the i-th line corresponds to the j-th first instruction pattern information can be determined by syntax analysis and lexical analysis of the program source on the i-th line.

(Step S1108) The instruction pattern conversion unit 1003 determines whether or not the j-th first instruction pattern information matches the condition of the condition storage unit 1002 based on the analysis result of the program analysis routine of step S1101. If the j-th first command pattern information matches the condition, the process proceeds to step S1109, and if the j-th first command pattern information does not match the condition, the process jumps to step S1115.
(Step S 1109) The instruction pattern conversion unit 1003 acquires second instruction pattern information paired with the j-th first instruction pattern information from the instruction pattern correspondence information storage unit 1001.
(Step S1110) The instruction pattern conversion unit 1003 converts the program source in the i-th row into an instruction pattern indicated by the second instruction pattern information acquired in step S1109.

(Step S1111) The instruction pattern conversion unit 1003 adds the i-th line source converted in step S1110 to the new program. It is assumed that the new program is stored in a certain file, for example, and a file is generated and opened at an initialization stage (not shown).
(Step S1112) The counter i is incremented. The process returns to step S1105.
(Step S1113) The counter j is incremented.

(Step S1114) The instruction pattern conversion unit 1003 determines whether or not the j-th first instruction pattern information exists. If the j-th first command pattern information exists, the process returns to step S1107, and if the j-th first command pattern information does not exist, the process goes to step S1115.
(Step S1115) The instruction pattern conversion unit 1003 adds the i-th line source to the new program. The source of the i-th line here is, for example, a comment line.
(Step S1116) The new program output unit 1004 outputs the converted program (new program). The output here includes processing that is only stored in a recording medium (such as a hard disk).

  Note that the first command pattern information does not match the conditions in the condition storage unit 1002, and the programmer uses input means such as a keyboard for the first command pattern in which the first command pattern is not automatically converted into the second command pattern. Then, manually rewrite the second command pattern. That is, although not shown, the automatic program conversion apparatus includes input means such as a keyboard and a mouse.

  Hereinafter, a specific operation of the program conversion apparatus in the present embodiment will be described. FIG. 12 is an instruction pattern information management table held by the instruction pattern correspondence information storage unit 1001. The command pattern information management table stores a plurality of records having “ID”, “first command pattern information”, and “second command pattern information”. “ID” is information for identifying a record. The instruction pattern information management table is a correspondence table used when the source line of the first instruction pattern information appearing in the conversion target program is converted so as to correspond to the paired second instruction pattern information. Specifically, when “First instruction pattern information” is “SOURCE-COMPUTER.XXXXXX.”, “Second instruction pattern information” “# DEL # * SOURCE-COMPUTER. XXXXXX. # CHG # SOURCE- COMPUTER. IBM-AS400. " “XXXXXX” indicates an arbitrary variable name. Further, “# DEL #” indicates that it has been deleted. “# CHG #” indicates a converted result. In this source, “*” indicates a comment line, and “#” to “#” indicate a comment.

  FIG. 5 is an example of an old program stored in the program storage unit 102. FIG. 8 is a command pattern appearance count management table showing the results of analysis by the analysis unit 103. Furthermore, it is assumed that the condition storage unit 1002 holds a condition that the program line of the first command pattern information whose number of appearances is two or more is converted into the second command pattern information.

FIG. 13 shows an example of a new program generated by the instruction pattern conversion unit 1003 converting and generating the old program of FIG. 5 and outputting the new program output unit 1004. In FIG. 13, a newly generated line in the new program is indicated by an underline. That is, in the new program, converted lines and unconverted lines are visually distinguished.
In the new program of FIG. 13, (1) is a part converted by the line “ID = 1” in the instruction pattern information management table. (2) is a portion converted by the row of “ID = 2” in the command pattern information management table.

  In the instruction pattern information management table of FIG. 12, for convenience of explanation, only the case where the new program n lines (n is a natural number) corresponds to one old program line, but the old program m lines (m is The new program n lines (n is a natural number) may correspond to a natural number of 2 or more.

  As described above, according to this embodiment, it is possible to analyze an instruction pattern included in a source program to be converted, and as a result, the source program can be efficiently or semi-automatically converted. Specifically, an instruction pattern having a frequency of appearance less than a certain amount that does not require development of a program for converting a source program is manually corrected, and the number of occurrences of a certain number of occurrences (for example, the number of appearances of 2 or more). By developing a program for converting the source program for only the instruction pattern and automatically converting it using the conversion program, the program can be converted efficiently. With such an automatic program conversion apparatus, for example, the operation of operating a program operating in a certain environment in a new environment can be performed very efficiently and safely.

  In the present embodiment, an instruction pattern with an appearance frequency less than a certain number that does not require development of a conversion program manually corrects the old source program. Therefore, the automatic program conversion device is used for manual correction. Input means are provided. The input means is, for example, a keyboard or a mouse.

  In the present embodiment, as shown in FIG. 14, in the new program after conversion, in a mode of visually distinguishing a place converted manually, a place automatically converted, and a place not converted, New programs may be stored and displayed. In the new program of FIG. 14, “@” to “@” are comments indicating manual work. “@ DEL @” indicates a manually deleted line, and “@ ADD @” indicates a manually added line.

  In the present embodiment, the condition for determining whether to perform automatic conversion or manual conversion is a condition that uses the number of appearances of the first command pattern information in the program as a parameter (in the above example, two or more times). However, it may be determined according to other conditions. Moreover, the structure which designates the 1st command pattern automatically converted by a user's input may be sufficient.

  The operations described in this embodiment may be realized by a computer-readable program. The program may be recorded and distributed on a recording medium such as a CD-ROM, may be distributed by network distribution, or may be distributed by broadcasting. This also applies to other embodiments. Note that the program that realizes the operation described in the present embodiment is a first instruction pattern information that is information indicating the instruction pattern of the old source program and a second instruction that is information indicating the instruction pattern of the new source program. One or more pairs of pattern information are stored, an analysis step for analyzing how many times the one or more first command pattern information appears in the old source program, and an analysis result for outputting an analysis result in the analysis step The description part of the old source program corresponding to the first instruction pattern information analyzed that the number of appearances of the first instruction pattern information in the output step and the analysis step is a predetermined number of times (the predetermined number is 2 or more) Is converted to correspond to the second instruction pattern information paired with the first instruction pattern information. A pattern conversion step, a new program output step of outputting a new program that is a result of converting the old source program in the instruction pattern conversion step, and the number of appearances of the first instruction pattern information in the analysis step is less than the predetermined number of times In order to execute a step of accepting an input for changing the description portion of the old source program to the new source program manually by the user with respect to the description portion of the old source program corresponding to the first instruction pattern information analyzed as being present Program.

  In this embodiment, the program is converted by one program automatic conversion device, but the processing may be shared by a plurality of devices. That is, the following program automatic conversion method may be realized by a plurality of devices. One or more pairs of first instruction pattern information, which is information indicating the instruction pattern of the old source program, and second instruction pattern information, which is information indicating the instruction pattern of the new source program, are stored in the storage unit.

That is, the automatic program conversion apparatus realizes the following program production method. It stores one or more pairs of first instruction pattern information, which is information indicating the instruction pattern of the old source program, and second instruction pattern information, which is information indicating the instruction pattern of the new source program, in the storage unit.
