Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a source program analysis device having a function of outputting an indication message by analyzing a source program, and a computer-readable recording medium recording the source program analysis program .
[0002]
[Prior art]
In the conventional source program analysis, all indication messages that point out a problem or a caution in the source program have been output. For this reason, a certain pointed message is output even if it is intentional and the output of the pointed message is not desired, and the output of the pointed message is processed mechanically. Messages and unnecessary indication messages were sometimes output.
[0003]
On the other hand, in order to improve such uniform processing, predetermined inhibition information is added to the description of the source program, for example, as “lint” which is known as a standard tool of UNIX, and the inhibition is performed. Some messages do not output a message indicating that there is information.
[0004]
As described above, in the conventional source program analysis, the output of the indicated messages is either to output all the indicated messages without suppression or not to output all the indicated messages suppressed by the suppression information. Was.
[0005]
[Problems to be solved by the invention]
Therefore, if the source program is corrected based on the pointed message and then the source program is analyzed again, outputting the pointed messages that do not need to be output many times is a task of checking unnecessary pointed messages. Since the repetition is performed, work processing cannot be reduced, and it is difficult to extract a really necessary indication message.
[0006]
Further, once the suppression information is set in the source program, the pointed message is not output thereafter, so that it is not easy to re-output the pointed message even when it is desired to reconfirm the pointed message.
[0007]
SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and to suppress the output of an unnecessary indication message, and to easily output the suppressed indication message when necessary.
[0008]
[Means for Solving the Problems]
FIG. 1 shows a block configuration example of the present invention.
The source program analysis device 1 includes a CPU, a memory, and the like, and includes a suppression information application setting unit 2, a suppression message output setting unit 3, a pointed message output processing unit 4, and a suppression information automatic insertion processing unit 5.
[0009]
The suppression information application presence / absence setting unit 2 is a means for setting whether or not to output an indication message even if suppression information exists in the source program 6 in accordance with an instruction from the user. Further, the suppression message output presence / absence setting unit 3 is a means for setting whether or not to output a pointed message when there is a pointed message suppressed by the suppression information in response to an instruction from the user.
[0010]
While the suppression information application presence / absence setting unit 2 sets whether or not to apply the suppression information, the suppression message output presence / absence setting unit 3 determines whether to output the suppressed indication message when the suppression information is applied. The setting is different.
[0011]
Based on the setting in the suppression information application presence / absence setting unit 2, the indication message output processing unit 4 indicates the indication regardless of the presence or absence of the suppression information if the setting is made to output the indication message even if the suppression information exists. If a message is output, and the output of the indicated message is suppressed when the suppression information exists, the output of the indicated message is suppressed according to the suppression information. In addition, based on the setting of the inhibition message output presence / absence setting unit 3, if a suppressed indication message is set to be output, the suppressed indication message is output. At this time, the suppression mark adding unit 41 adds a specific symbol or the like to the suppressed indication message and outputs the message, so that it is possible to distinguish at a glance whether the output is a suppressed indication message or another indication message. Output to
[0012]
The suppression information automatic insertion processing unit 5 includes means for selecting an indication message whose output is to be inhibited from the indication list of the indication message, and automatically inserts information for suppressing the selected indication message into the source program 6. With means to do.
[0013]
The source program 6 is a source program to be analyzed.
A program for realizing each of the above processing means by a computer can be stored in a suitable storage medium such as a computer-readable portable medium memory, a semiconductor memory, and a hard disk.
[0014]
The present invention operates as follows.
When the suppression information application presence / absence setting unit 2 sets whether or not to output the indication message when the suppression information exists in the source program 6, if the setting is made to output the indication message even if the suppression information exists, The indication message output processing unit 4 outputs an indication message as a result of analyzing the source program 6 even if the inhibition information is present. When the setting is made such that the indication message is not output when the suppression information exists, if the suppression information is found at the point indicated by the analysis of the source program 6, the indication message is not output. As a result, it is possible to arbitrarily select whether or not to output the indicated message according to the suppression information.
[0015]
Also, even if the suppression information application presence / absence setting unit 2 sets the suppression of the output of the indication message when the suppression information is present, the suppression message output presence / absence setting unit 3 does not include the indicated message. When the setting is made to output the pointed message, the suppression information in the source program 6 is detected, and the pointed message output processing unit 4 outputs the suppressed pointed message. When it is set not to output the pointed message when there is the suppressed pointed message, the pointed message output processing unit 4 does not output the suppressed pointed message. As a result, the suppressed pointed message can be arbitrarily output if necessary.
[0016]
When the pointed message output processing unit 4 outputs the pointed message that has been suppressed, the suppression mark attaching unit 41 determines that the outputted pointed message is the one that has been suppressed, for example, by adding a suppression mark to the pointed message. Output in an understandable output format. This makes it possible to distinguish at a glance the pointed-out message that has been suppressed and the pointed-out message that has not been suppressed, and the efficiency of the work of examining the analysis results can be increased.
[0017]
In addition, the suppression information automatic insertion processing unit 5 arbitrarily selects an indication message whose output is to be suppressed from the indication message output list, and automatically includes information for suppressing the selected indication message in the source program 6. Since it can be inserted, it is possible to set the suppression information in the unnecessary indication message by a simple operation using a GUI (Graphical User Interface) or the like.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described.
FIG. 2 is a flowchart showing a processing outline of the present embodiment.
[0019]
The suppression information application presence / absence setting unit 2 sets in advance whether or not to output an indication message when the suppression information is present in the source program 6 (S1). It is set whether or not to output a pointed message even when there is a part where the output of the pointed message is suppressed (S2).
[0020]
It is determined whether or not a setting is made so as to output an indication message even if the suppression information is present in the source program 6 (S3). Proceed to processing. When the inhibition information is included in the source program 6, if it is set not to output the indication message, the process proceeds to step S4.
[0021]
In the process of step S4, it is determined whether or not there is inhibition information in the source program 6. If there is no inhibition information in the source program 6, the process proceeds to step S8, and the inhibition information is detected in the source program 6. In this case, the process proceeds to step S5.
[0022]
Next, in the process of step S5, it is determined whether or not the suppressed indication message is to be output. If the suppressed indication message is to be output, a suppression mark is added to the suppressed indication message. In addition, output is performed so that the suppressed message and the non-suppressed message can be identified (S6). If the suppressed indication message is not output, an indication message other than the suppressed indication message is output (S7). In the case of the GUI, the processing of S2 can be performed after outputting S6 and S7, and the processing of S5 can be repeated again. Thereafter, the process proceeds to step S9.
[0023]
In the process of step S8, all the indicated messages are output even if the inhibition information exists.
Subsequently, in the process of step S9, when the suppression information automatic insertion processing unit 5 selects a pointed message whose output is to be suppressed in the analysis of the next source program 6 in the output list of the pointed message, the source message 6 Is automatically inserted into the server (S9).
[0024]
FIG. 3 shows an example of setting whether or not suppression information is applied.
FIG. 3A is an example of a suppression information application setting screen when setting whether or not to apply the suppression information is performed using a GUI, and FIG. 3B is a diagram illustrating whether or not to apply the suppression information. This is an example in which the setting is performed by a command option when a source analysis program (source checker) for realizing the source program analysis device 1 is started.
[0025]
When setting the application of the suppression information using the suppression information application setting screen shown in FIG. 3A, select the source program 6 to which the suppression information is to be applied from a list of source programs to be analyzed or a directory. After that, the “D” point is marked by clicking the mouse on the suppression information application setting screen. With this mark, a setting is made so that the indication message is not output if the inhibition information is present in the source program 6.
[0026]
Also, as shown in FIG. 3B, by describing "-d" as an option of the start command of the source analysis program (program name = pgr), it is possible to similarly set that the suppression information is applied. it can. In the figure, "%" is a prompt for command input, and "ac" and "bc" are file names of the source program 6 to be analyzed. The output of the indication message as the analysis result is a standard output (screen) in this example.
[0027]
FIG. 4 shows an example of setting whether to output a suppressed indication message.
FIG. 4A is an example of a screen for setting the output of a suppressed indication message when the setting of whether to output the suppressed indication message is performed using the GUI, and FIG. In this example, whether or not to output a message is set by a command option when starting a source analysis program (source checker).
[0028]
When the setting to output a suppressed message is made by using the suppressed message output setting screen shown in FIG. 4A, the list of the source programs to be analyzed or the directory of the suppressed message is displayed. After selecting the source program 6 that needs to be output, the “レ” point is marked by clicking the mouse or the like on the output screen for setting the output of the message to be inhibited. With this mark, even if the suppression information is applied, a setting is made to output the message indicating the suppression.
[0029]
Also, as shown in FIG. 4 (B), by describing "-o" as an option of the start command of the source analysis program (program name = pgr), it is set to output the similarly pointed out message which is suppressed. be able to.
[0030]
FIG. 5 is a diagram illustrating an example of the suppression information.
FIG. 5A shows an example of the suppression of the indication message by the standard include. In the header file of “standard.h” called by the “#include” statement of the source program A shown in FIG. 5 (A), there is no syntax error but meaningless conditional expressions that are not normally used. When there is a pointed-out point (“if (x = 1)” in this example), the standard. Since h is enclosed in “<>”, it is recognized as a standard include, and no indication message is output even if there is an indication. The source program analyzer 1 regards such a standard include as suppression information.
[0031]
FIG. 5B shows an example of the suppression of a pointed message by a comment. As shown in FIG. 5 (B), there is a description that should be pointed out (“if (x = 1)” in this example), but a special character string “ / * pgr0040 * /” Is attached as a comment, the source program analysis device 1 does not output a message indicating this point in principle. In this case, the comment “ / * pgr0040 * /” is the suppression information. Note that “ 0040” in “ / * pgr0040 * /” is a message number in a number of indication messages, and indicates that only the indication message with the number 0040 is to be suppressed from being output. If there are other types of indications in the component with the same description, the output of the indication message is not suppressed.
[0032]
For example, when the output of a plurality of indication messages with message numbers 0040 and 0041 is suppressed, the description of the suppression information is " / * pgr0040, pgr0041 * /".
[0033]
FIG. 6 is a diagram illustrating an example of a process of automatically inserting suppression information.
As shown in FIG. 6A, the pointed message output processing unit 4 outputs a pointed message list based on the setting of the suppression information application presence / absence setting unit 2. When selecting a pointed message whose output is to be suppressed from this list, the user places the cursor on the pointed message and instructs insertion of the suppression information by clicking a menu or the pointed message. As a result, an inhibition information automatic insertion screen as shown in FIG. 6B is displayed, and the "execute" button on this screen is clicked. When the “execute” button is clicked, the suppression information automatic insertion processing unit 5 inserts a comment “ / * pgr0040 ” as shown in FIG. 6C, for example, in a portion corresponding to the selected indication message in the source program 6. * / "Is automatically inserted as suppression information.
[0034]
FIG. 7 is a diagram illustrating an example of the indicated message list including the suppressed indicated messages. If a suppressed indication message is set to be output, the suppression mark attaching unit 41 puts a suppression mark (*) on the suppressed indication message, so that the indication message is suppressed in the indication message list. Make sure they are things. This allows the user to re-check only the suppressed message when referring to the indicated message, or, conversely, ignore the suppressed message and leave only the non-suppressed message. Checking with attention can be done easily.
[0035]
【The invention's effect】
As described above, according to the present invention, when the suppression information of the pointed message is present in the source program, this is output / non-output, and it is clearly indicated that the pointed message is the pointed message to which the suppression information is added. Can be output. As a result, it is possible to greatly improve the work efficiency of confirming a message pointed out as a result of analyzing the source program. In addition, it is possible to easily set the suppression information for the indication message requiring the suppression.
