[Industrial applications]
The present invention relates to a document processing device such as a DTP or a word processor.
[0002]
[Prior art]
In recent years, in a document processing apparatus such as a DTP or a word processor, when creating a document, input characters and control codes are temporarily stored in a text buffer such as a message bar. Here, the control code refers to a code that is input when an editing operation such as a character typeface, a character size, and alignment processing is performed. The input character is edited in accordance with the control code, and as a result, on a screen of a screen. Is displayed. Further, the user can easily perform the editing work while checking the control code on the message bar, instead of performing the editing work while viewing the entire document. However, in a conventional document processing apparatus, even if only a part of a plurality of item settings is changed, all control codes are inserted into the text buffer, including the unchanged items. .
[0003]
[Problems to be solved by the invention]
However, in such a document processing device, the text buffer is not effectively used due to insertion of an unnecessary control code, and a user can recognize a correct control code by displaying many control codes in a message bar. There was a problem that it was lost and confused.
[0004]
Therefore, an object of the present invention is to provide a document processing device that can effectively use a text buffer without inserting unnecessary codes into the text buffer.
[0005]
[Means for Solving the Problems]
The present invention provides an input unit for inputting a set value, a first storage unit for storing the set value input by the input unit as data, and a second storage unit for storing data of a character cursor position in a document. A comparing means for comparing the data of the first storage means and the data of the second storage means, and when the two data compared by the comparing means are different data, the data of the input setting value is used as the setting information. There are provided setting means for setting and display means for displaying the contents of the setting information.
[0006]
[Action]
According to the above configuration, the data of the set value input from the input means and the data of the cursor position are compared, and only when these data are different, the input set value data is displayed.
[0007]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a document processing apparatus according to one embodiment of the present invention, and 1 is a CPU (central processing unit) for controlling the apparatus and performing data processing. The CPU 1 corresponds to a comparing unit and a setting unit. Reference numeral 2 denotes an input unit such as a keyboard for allowing a user to input necessary information such as operation commands, 3 denotes a ROM (Read Only Memory) for storing programs and the like, and 4 denotes a RAM (Random Access Memory) for storing various data. 5 is a text buffer in the RAM 4 for storing characters and control codes input and set by the user as text, and 6 is various data (for example, characters) A cursor buffer for storing size, Japanese document, European document, line start position (line start position), line end position (line end position), and the like. 8 is a character buffer for temporarily storing a control code to be stored in the text buffer 5. A §, 20 is CRT (cathode ray tube) as a display device.
[0008]
The operation of the thus configured document processing apparatus of the present embodiment will be described below with reference to the flowcharts of FIGS. 2 and 3 are flowcharts of the document processing apparatus according to an embodiment of the present invention, FIG. 4 is a data configuration diagram of a setting buffer in the embodiment, and FIG. 5 is a data configuration diagram of a cursor buffer in the embodiment.
[0009]
In step 1, during the document processing, when the line start / end setting process is selected from the document processing items, the line start position and line end position in the setting buffer 7 are added to the line start / line end position in the cursor buffer 6. The end-of-line setting data is set as the initial value. The cursor buffer 6 stores various data at the cursor position. The cursor buffer 6 corresponds to a second storage unit. When the start and end of the line are set in step 2, the set values are stored at the start position and the end position of the line in the setting buffer 7. Here, the setting buffer 7 temporarily stores the data value of the set value when the feed size, typeface, head of line, end of line, etc. are set by the user. The setting buffer 7 corresponds to a first storage unit.
[0010]
In step 3, the data at the start position (caret position) of the line in the setting buffer 7 is compared with the data at the start position of the line in the cursor buffer 6, and if it is determined that the two data are different data, step 4 , The data at the start position of the line in the setting buffer 7 is converted into parameters and set in the character buffer 8, and when it is determined that the two data are the same data, the process of step 5 is performed.
[0011]
In step 5, similarly to the processing in step 3, the data at the end position (caret position) of the line in the setting buffer 7 and the data at the end position of the line in the cursor buffer 6 are compared. When it is determined that the data at the end position of the line in the setting buffer 7 is converted into a parameter in step 6 and added to the character buffer 8 and when it is determined that the two data are the same data, Step 7 is performed.
[0012]
When a control code including a parameter is set in the character buffer 8 in step 7, the control code in the character buffer 8 is inserted into the text buffer 5 at the cursor position in step 8, and in step 9, When information such as sentences and functions and the created document are redisplayed on the CRT 20, the cursor position information is updated in the cursor buffer 6 in step 10, the processing ends, and the control code is not set in the character buffer 8. Ends the processing as it is.
[0013]
Next, a specific operation of the document processing apparatus according to the embodiment of the present invention will be described with reference to an example. FIG. 6 is an exemplary view showing the specific contents of the text buffer before the change in the embodiment, FIG. 7 is an exemplary view showing the specific contents of the text buffer after the change in the embodiment, and FIG. FIG. 3 is an exemplary diagram showing specific contents of a buffer.
[0014]
In this embodiment, as shown in the text buffer 5 of FIG. 6, the current line head / line end information of the cursor 15 is such that the control code 13 at the line start position is "1.0" point from the line head, and The control code 14 at the end position is "530.0" points from the beginning of the line.
[0015]
Here, when the user selects the line start / line end setting process from the document processing items during document creation, the line start position and line end position items in the setting buffer 7 are added to the cursor buffer 6 in FIG. The data 11 “1.0” and the data 12 “530.0” of the line start / line end setting are transferred to the setting buffer 7 and set.
[0016]
When the start and end of the line are set from the input unit 2 such that the start position of the line is "50.0" points from the start of the line and the end position of the line is "530.0" points from the start of the line, as shown in FIG. In the setting buffer 7, data 9 "50.0" and data 10 "530.0" are stored in the items of the line start position and the line end position.
[0017]
Next, data 9 “50.0” at the start position of the line in the setting buffer 7 in FIG. 4 is compared with data 11 “1.0” at the start position of the line in the cursor buffer 6 in FIG. Based on the processing result, the two data are determined to be different values, and the data 9 “50.0” in the setting buffer 7 is converted into a parameter and set as the control code 17 in the character buffer 8 of FIG.
[0018]
Next, data 10 “530.0” at the end position of the line in the setting buffer 7 in FIG. 4 is compared with data 12 “530.0” at the end position of the line in the cursor buffer 6 in FIG. Since the two data are determined to have the same value from the processing result, no control code is set in the character buffer 8.
[0019]
Next, as shown in FIG. 7, the control code 17 at the start position of the line in the character buffer 8 of FIG. 8 is inserted into the text buffer 5 as the control code 16, the text is reassembled, and displayed on the CRT 20.
[0020]
Next, the data of the line head setting of the cursor buffer 6 in FIG. 5 is updated to “50.0”. It should be noted that this processing method can be used not only for the line head / line end setting but also for "font" and "feed size".
[0021]
【The invention's effect】
According to the present invention, the text buffer can be used effectively without inputting unnecessary control codes.
