Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document edit processing device, and more particularly to management and display control of document data.

[0002]

2. Description of the Related Art Conventionally, in a document edit processing apparatus such as a word processor, one document is divided into, for example, page-unit document data and managed only as a rough and sequential sequence of data. When editing a certain document data, since the data on the memory in which the document data is stored is directly edited, the history of the edited data for addition and deletion of the document data is not completely managed. There wasn't. Therefore, in the conventional document edit processing device, when trying to edit (insert, delete, copy, etc.) the document data displayed on the display device, for example, after specifying the edit position and the delete range, Although the editing operation is performed, only the editing result is displayed at the stage when this operation is completed, and the insertion and deletion points cannot be visually judged.

FIG. 11 shows a conventional document data editing operation. First, an event input such as a key operation from the keyboard or a mouse click operation is performed (step S1),
A region for editing position designation, deletion, insertion, etc. is designated (step S2). Then, according to the input editing operation, if a certain character string is to be deleted, this character string is deleted and the document data is updated (step S3). Further, here, only the edited results that have been deleted are saved, and no distinction is made between before editing and after editing. Then, when the editing operation is completed (step S4), the display state of the display device is updated with the edited document data (step S5).

Further, when an attempt is made to restore the original document after editing certain document data, there are the following two types of restoration processing. That is, the first method is a method in which the document data before editing is loaded from the file storing the document data to restore all the states before editing. As the second method, the state before editing (the insertion position and the insertion character string during the character string operation, the deletion position and the deletion character string in the case of character string deletion processing) is stored and the edited data is restored. This is a method in which only one function is returned to the state before editing.

FIG. 12 is a diagram for explaining the display of the second method. That is, (a) shows a state before editing, and (b) shows a state in which a deletion range is designated. In this case, the deletion range is the character string "cdefgh", which is displayed in a display color different from that of other parts, and is thus distinguished from the character string of the unedited part. Then, (c) shows a deletion completion state, and after the deletion range is designated, the character string is deleted by a predetermined key operation.
Here, when trying to recover from the state of (c) to the state of (a), it was usually possible to recover only immediately after deletion.

[0006]

As described above, in the conventional document edit processing device, the history of the edited document data is not managed, so that the following problems occur. That is, as described above, since the recovery processing unit of the document data is the entire document unit or the data unit related to one editing operation, it is not possible to recover only a part of the document data after performing the editing a plurality of times. In addition, it is impossible to visually display the document data before and after the editing, and it is impossible to select the restoration point and refer to the document data. The present invention has been made in order to solve the above-mentioned conventional problems, and a document edit processing device having improved operability such as visually distinguishing the state before and after editing document data. The purpose is to provide.

[0007]

A document edit processing apparatus according to the present invention uses a document data management unit for managing document data by dividing it into edit states, and a document using the document data managed by the document data management unit. The document data editing processing means for editing and the display processing means for displaying the document edited by the document data editing processing means on the display device in a state where the distinction between the editing states can be visually judged. is there.

[0008]

In the document edit processing device of the present invention, the document data management means manages the document data according to the edit state such as unedited, deleted, and added. When performing document editing, the document data editing processing means performs document editing using the document data managed by the document data management means, and the edited document is distinguished by the document data display processing means. It is displayed on the display device in a visually determinable state. Therefore, even after editing a plurality of times, the document before editing can be restored, and the document data before and after editing can be easily referred to.

[0009]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a document edit processing device of the present invention. The apparatus shown in the figure comprises a document edit integration processing section 1, an input processing means 2, a document data management means 3,
It is composed of a document data edit processing means 4 and a document data display processing means 5, and is composed of a program or a dedicated processor. The input processing unit 2 has a function of processing an event from the keyboard 6 and the mouse 7, and the document data management unit 3 edits the document data in an edited state (unedited, deleted, added, etc.) as described later. ) It is a means to manage separately. The document data editing processing means 4 has a function of editing the document data managed by the document data managing means 3 such as adding, deleting and copying the document data. It has a function of displaying the document data managed by the document data management means 3 on the display device 8 according to the editing state. The display device 8 in the figure
Shows an example in the case of “display edit data” which will be described later. The document edit integration processing unit 1 also has a function of integrating and controlling the input processing unit 2 to the document data display processing unit 5.

FIG. 2 is an explanatory diagram of the document data management method of the document data management means 3. That is, the document data management unit 3 has management information for hierarchically holding the document data in the memory, and manages the document data by dividing it into logical edit units. For example, the document data management information refers to the whole of a certain document data, and the document data management information 1, the document data management information 2 ... Are the blocks of the whole document data divided into blocks such as chapters and paragraphs. The document data 10 and 20 indicate the information of the block. Also, the document data management information 1.
1, document data management information 1.2, ... Have a parent-child relationship with the document data management information 1, and refer to information in which the document data 10 is managed for each editing unit. Furthermore, the document data 110 and 120 are the document data of the minimum unit. Document data including document management information and document data attributes is stored in a random access memory, a floppy disk device, a hard disk device, or the like. Although not shown in the figure, the document data management information 2
Also, similar to the document management information 1, there is document data of minimum data having a parent-child relationship.

FIG. 3 is an explanatory view of the document data management state of the document data management means 3. Here, the document data management information corresponds to the document data management information 1.1, 1.2, ... In FIG. 2, respectively, and is a so-called sibling relationship with respect to the parent-child relationship with respect to the document data management information 1. There is. Further, the pointer (hierarchical data) to the management information of the document data is a pointer of the address of the parent document data, and here, the document data management information 1
3 shows the start address of the document data 10 managed by. Further, the pointer to the document data management information (within the minimum data) indicates the rear end position of the minimum data. The document data attribute indicates the edit state and includes unedited “O”, added “A”, deleted “D”, and deleted additional information “AD” (note that deleted additional information “AD”). Is shown in FIG.
Not shown). Further, the pointer to the document data indicates where in the document data the document management information is stored. FIG. 4 shows an example of the document data shown in FIG. In this way, the document data management method of the minimum data unit is divided and managed according to the editing state,
These are connected in a list by the document management information.

Next, the operation of the document edit processing apparatus having the above configuration will be described. FIG. 5 is a flowchart showing document data update at the time of document edit processing. First, when an event is input from the keyboard 6 or the mouse 7 during the document editing process, the document data management means 3 obtains the document data management information corresponding to the editing position (step S).
1). Here, when the editing operation is addition of a character string or the like (step S2), two pieces of document data management information are added, and the pointer is rearranged so as to be after the searched document management information (step S3). Then, the address of the document data at the additional position is set in the second added document data management information (step S4), and the address of the additional document data is set in the first added management information (step S5).

FIG. 6 is an explanatory diagram of the addition process. That is, it is assumed that the document data is managed in a certain block {state of (a)}. Add (insert) a string here
In the case of {(b)}, the document data of the original block is divided by inserting the character string, and as shown in (c), the document data of the additional character string and the document data of the additional block are added to the document data of the original block. Two pieces of document data of the original block document data divided by the additional character string are added as the document management information. Further, the pointers of the two added document data are set to be after the document data. At the same time, the address of the document data at the additional position (corresponding to the address at position A) is set in (the document data of) the document data management information added second, and the address of the additional document data (corresponding to the address at position B). Is set in (the document data of) the document management information added first.

If the editing operation is deletion in step S2, as in the case of the above-described addition processing,
Two pieces of document data management information are added, and the pointer is rearranged so as to be after the searched document data management information (step S6). Then, the address of the document data at the end of the deletion range is set in the document data management information added second (step S7), and the address of the document data at the deletion position is set in the document data management information added first. (Step S8). In this case, if the addition character string of the addition process shown in FIG. 6 is replaced with the deletion character string, it can be considered that the addresses similarly correspond to the positions A and B.

Next, the recovery of the document data will be described. FIG. 7 is a flowchart of document data recovery.
First, the document data management means 3 searches for the corresponding document data management information from the recovery range of the document data designated by the operator such as a certain part of the document data or all documents (step S1). When the corresponding document data management information is requested, the document data attribute of the document data management information is checked (step S2). If this is deleted or unedited, the document data management information list is followed and the next document data management is performed. Information is requested (step S3). That is, the document data management information in this case is the same as that before the restoration.

If the document data attribute is deletion or addition of additional data in step S2, the document data and the document data management information linked to this document data management information are deleted (step S4), and the previous document data is deleted. The management information and the document data management information are connected by a pointer, and the document data management information is removed from the list (step S5). That is, it can be considered that the states from (c) to (a) of FIG. Then, the process proceeds to step S3 to obtain the next document data management information. After that, it is checked whether or not there is document data management information in the recovery range (step S6). If the document data management information still remains, the process returns to step S2 to check the attribute of the document data. If no document data management information remains, the process ends.

Next, the display processing of the document edit data will be described. FIG. 8 is a flowchart showing the document edit data display processing. First, the document data management means 3 searches for the corresponding document data management information from the display range of the document data designated by the operator such as a certain part of the document data or all documents (step S1). Next, the document data management means 3 confirms the display mode selected by the operator, that is, whether the display mode is to display only the edited result or to display the edited data in the middle of reaching the edited result. Perform (step S2).

If the mode for displaying only the edited result is selected, the document data attribute of the document data management information is checked (step S3). If the attribute of certain document data is added, this document is added. The document data display processing means 5 sends a signal to display the data in blue (step S4), and if the attribute of certain document data is unedited, the document data is controlled to be displayed in black (step S4). S5). If the document data is deleted or additional data is deleted, no display is made. After that,
The list of document data management information is searched for the next document data management information (step S8), and if there is document data management information in the display range (step S9), the process returns to step S2 and the above operation is repeated to display the range. If there is no document data management information of, the process ends. FIG. 9 shows a display example thereof. That is, when the character string “fghij” is added to the unedited data whose edit history is, and then the character string “opqrst” is deleted, the character string “opqrst” is deleted in the displayed screen. Only the edited result is displayed.

Further, the display mode is "display edited data".
If it is, the attribute of the document data is checked (step S6) as in the case of “display only the edited result” described above, and if the attribute of the document data is added or unedited, “edit” is performed. Similar to the case of "display only result", control is performed so that the additional document data is displayed in blue and the unedited document data is displayed in black (steps S4 and S5). If the attribute of the document data is deletion or deletion of additional data, the document data is controlled to be displayed in gray (step S7). After that, the next document data management information is obtained (step S8), and if there is document data management information in the display range (step S9), the above operation is repeated. FIG. 10 shows a display example when editing data is also displayed. In other words, the edit history is similar to the above-described display of only the edited result, and the character string “fg
If there is the addition of "hij" and then the deletion of the character string "opqrst", the displayed screen is the deleted character string "opqrs".
"t" is also displayed in gray. As described above, in the above-described embodiment, since the document data is managed by being classified according to the edit state, it is possible to restore the state before the edit even when the edit operation is performed a plurality of times, and the state before the edit is performed. It is possible to display such that the state after editing can be visually judged.

In the above embodiment, the unedited data is displayed in black and the additional data is displayed in blue. However, the display color is not limited to such a display color, and the edited state of the document data can be visually displayed. If the display can be judged,
It may be of any type such as reverse display or shaded display.

[0021]

As described above, according to the document edit processing apparatus of the present invention, the document data is managed according to the edit state,
In addition, since the display is configured so that the editing status of the document data can be visually judged, the editing data restoration operation can be performed for each editing unit, for example, even after multiple edits, the document before editing is restored. Yes, and in the display,
Since the edited state of the document data can be known at a glance, it is possible to easily refer to the document data after the editing and before the editing. Therefore, it is possible to improve the operability of the document editing processing apparatus.
