  According to the present invention, it is possible to search only the part to be compiled of the source code by searching for the target character string while translating the source code, and the efficiency of editing can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram for explaining the outline of a system for executing a source code editing apparatus (editor) according to the present invention, and is composed of a CPU (Central Processing Unit) for controlling the entire system. A control unit 101, an operation input unit 102 for a user to input for setting, a memory 103 used as a work area of the control unit 101, application software including an editor, or a source code file to be edited are stored. For example, a storage device 104 configured by an HDD (Hard Disk Drive) and a display unit 105 that displays a source code and displays the setting when the user performs the setting.

  Next, it is executed between the source code editing apparatus (an editor with a source code translation function) according to the present invention and a storage device such as an HDD (Hard Disk Drive) in which the source code file to be edited is stored by the editor. An outline of the processing to be performed will be described with reference to FIG.

  The editor 201 includes an option setting 202 as a function, a source code search engine 203, a search A 204, and a source code display 205.

  The option setting 202 has a function of setting a script file for translating the source code based on the operation of the operation input unit 102 by the user, and further setting a character to be interpreted as a comment by the search engine 203.

  The source code translation engine 203 interprets the script file set in the option setting 202 and executes translation of the source code, specifies the character and preprocessor instruction to be interpreted as a comment, the source code to be compiled, and its source Generate a "translated source code file" consisting of the line numbers of the code. Further, the source code translation engine 203 searches the generated “translated source code file” for a character string given from the search A described later, and sends the search result to the search A.

  The search A 204 sets a search character string and a search mode based on the operation of the operation input unit 102 by the user, that is, sets a translation search mode or a normal search mode. In the translation search mode, the source code translation engine A process for activating this is performed for 203. Further, the search A 204 receives the search result from the source code translation engine 203, searches the source code based on the search result, and sends the search result to the source code display 203.

  The source code display 205 has a function of displaying the source code and displaying the contents of the source code file based on the display position data given from the search A 204.

  The storage device 104 stores a source code file 206 to be edited, a script file 207 for compilation, and a source code file 208 translated by a translation engine.

  Note that the preprocessor instructions are #include, #define, #undef, #ifdef, #ifndef, #if, #else, #elif, #endif, and the comment ranges from “/ *” to “* /”, or A character string from “//” to a line feed code or from “//” to an EOF (End Of File) code.

  Details of the processing in the editor configured as described above will be described in more detail with reference to the flowchart shown in FIG.

  In FIG. 3, the editor starts in step S301, and in step S302, an editor is activated by a user operation. At this time, the contents of the source code file are displayed on the source code display 205.

  In step S303, option setting is activated. Here, the user makes full use of the operation input unit 102 while viewing the display screen of the display unit 105, and a script file for translating the source code and a character to be interpreted as a comment. Is specified. That is, a script file is designated in step S304, a character to be interpreted as a comment is designated in step S305, and option setting is terminated in step S306.

  Next, in step S307, the search A204 is activated by the user's operation on the operation input unit 102, and a search character string is designated in step S308. The user also performs this process based on the screen display of the display unit 105.

  When the designation of the search character string is completed, the translation search mode is designated by the user in step S309. Next, when the user presses the search button of the operation input unit 102 in step S310, the search A 204 activates the source code translation engine 203 in step S311.

  The activated source code translation engine 203 executes source code translation and character string search in step S312. At this time, the source code translation engine 203 interprets the script file specified in the option setting, executes the translation, further identifies the characters to be interpreted as preprocessor instructions and comments, and excludes them as “translated source” A “code file”, ie, a secondary source code file is generated.

  Next, the source code translation engine 203 executes a search of the character string given from the search A 204 for the “translated source code file”, and when the search is executed for all the “translated source code files”, the step is performed. In step S313, the search process ends.

  Next, in step S314, the source code translation engine 203 sends the search result to the search A 204. If there is a target character string as a result of the search, there is no line number or character string. In this case, 1 is added to the last line number or zero is sent to the search A as a search result.

  Next, in step S315, the search A 204 searches the source code file based on the search result sent from the source code translation engine 203. That is, the search A 204 jumps to the line number sent from the source code translation engine 203, searches the target character string from the first column, and obtains the position information of the target character string.

  In step S316, the search A 204 passes the position information of the target character string obtained as a result of the search to the source code display 205, and the processing as the search A 204 is terminated in step S317.

  Next, in step S318, the source code display 205 causes the display unit 105 to display the source code file including the searched character string, and in step S319, all processing is terminated.

  In FIG. 3, steps S304, S305, S309, S311, S312, S313, and S314 surrounded by diagonal lines are characteristic processes of the present invention and are new processes that did not exist in the past.

  As described above, according to the present invention, in an editor having a function of searching for a specific character string in a source code, a preprocessor instruction that includes a source code translation engine, translates a source code file, and is not subject to compilation, , Excluding comments, generating a translated source code file (secondary source code file) and searching for the target character string in the translated source code file. If it is detected, the line number is passed to search A, and the search A is searched for the character string of the line number. Therefore, the target character string search is executed by excluding the range not to be compiled. Therefore, editing efficiency can be improved.

  FIG. 4 shows the source code translation engine shown in FIG. 2 in detail. The editor 401 includes a source code translation engine 402, option settings 403 and search A 404 as functions, and a storage device 405.

  The source code translation engine 402 includes source code translation 406, file creation 407, file input / output 408, option recognition 409, search A interface 410, and search B 411 as functions.

  The source code translation 406 translates the preprocessor instructions #include, #define, #undef, #ifdef, #ifndef, #if, #else, #elif, #endif from the option setting 403 via the option recognition 409. Based on the given script file and comment information, the comment is also translated.

  The file creation 407 creates a source code file (secondary source code file) translated by source code translation. At this time, the source code lines of preprocessor instructions and comments that are not to be compiled are not included in the file.

  As shown in FIG. 5, the file format created by the file creation 407 is such that the first column of the source code enters the fifth byte as the record content 502 of the file with respect to the display image 501 in the editor. The line number of the source code is entered in the 4th byte.

  The file input / output 408 sends the translated source code file created in the file creation 407 to be stored in the storage device 405, or receives the source code file or script file read from the storage device 405, It has a function of sending to source code translation 406.

  The option recognition 409 recognizes the option information given from the option setting 403, specifies the character to be interpreted as a comment, and outputs it to the source code translation 406.

  The search A interface 410 receives the source code translation engine start command given from the search A 404, starts the source code translation engine 402, and derives the search character string information given from the search A 404 to the search B 411.

  The search B411 searches the translated source code file based on the search character string information given from the search A404, and derives the result to the search A via the search A interface 410.

  The storage device 405 stores a source code file 412 to be edited, a script file 413 for causing the source code translation 406 to execute source code translation, and a translated source code file 414. The translated source code file 414 is generated by the file creation 407 of the source code translation engine 402 and sent via the file input / output 408. The script file 413 is for executing the source code translation 406.

  In FIG. 4, solid line arrows indicate the flow of data necessary for translating the source code, rough dotted lines indicate the flow of data constituting the translated source code file, and fine dotted lines indicate The flow of data when search B411 searches for a search character string is shown.

  The process of the embodiment shown in FIG. 4 will be described in more detail with reference to the flowchart of FIG.

  In FIG. 6, the process starts in step S601. In step S602, the source code translation engine 402 is activated, and the option recognition 409 obtains a script file for translating the source code in step S603 from the option setting 403. In step S604, character information to be interpreted as comments is acquired, recognized, and passed to the source code translation 406.

  In step S 605, the file input / output 408 reads the source code file 412 from the storage device 405 and passes it to the source code translation 406. Next, in step S606, the source code translation 406 translates the source code file and passes the translated content to the file creation 407.

  In step S <b> 607, the file creation 407 creates a translated source code file from the data received from the source code translation 406 in the storage device 405 via the file input / output 408.

  Next, in step S608, the target character string is searched in the source code file in which the search B is translated. If the target character string exists, the line number is set. If not, the line number is set to the final line number. A search result obtained by adding 1 or zero is used as a search result, and the search result is passed to the search A interface 410 in step S609. The search A interface 410 passes the received search result to the search A in step S610.

  In step S611, the source code translation engine 402 is terminated, and in step S612, the process is terminated.

  As described above, according to the present invention, when searching for a target character string in the source code with the editor, the source code is translated, and the translated source excluding preprocessor instructions and comments that are not to be compiled Since a code file is separately generated and a search is performed to determine whether or not the target character string exists in the translated source code file, the search efficiency can be improved.

  The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the spirit of the present invention.
