Abstract

PURPOSE:To enable plural users to simultaneously edit the same text by merging the differences produced between the text and the edited texts of the users to produce an edited final text and then performing the replacement of texts. CONSTITUTION:When the coincidence is secured between the text identifier of a text identifier store area 5 and the text identifier of a text identifier store file 10, an edited text of an edited text store area 6 is stored in the file 10. If no coincidence is obtained between both text identifiers, the difference between the original text of an original text store area 4 and the edited text of the area 6 is extracted by a difference extraction means 7. Then the difference merge result is obtained by a difference merge means 8. A text merge means 9 merges the original text with the difference merge means 9, and an edited final text is produced in the area 6. This final text is written into the file 10 together with a new text identifier. Thus plural users can edit the same text at one time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a text management method, and in particular, a method for reading text from a text storage file, editing the text, and then storing and managing the edited text in the original text storage file. Concerning text management methods.

[Conventional technology]

Conventionally, in this type of text management method, the text in the text storage file is read into a buffer for the text collection, edited on the buffer, and then the edited text is replaced with the text in the original text storage file all at once. The common method was to

[Problem to be solved by the invention]

In the conventional text management method described above, the general method is to read the text in the text storage file into a text editing buffer, edit it on the buffer, and then convert the edited text with the text in the original text storage file all at once. Therefore, when multiple users update the same text, for example, while user A is editing the text, user B also edits the same text and replaces it with the text in the text storage file before using it. There is a drawback that when user A finishes editing and replaces the text, the edits made by user B are no longer reflected in the text.

Also, to compensate for this drawback, there is a method that does not allow multiple users to edit the same text at the same time, but this method has the drawback that multiple users cannot edit the text at the same time. be.

In view of the above-mentioned points, an object of the present invention is to replace the text that was originally read and the text of each user when another user has rewritten the text after the text was first read when replacing text. Multiple users can edit the same text at the same time by merging the differences with the edited text, creating a final edited text that reflects each user's edits, and then replacing the text. The object of the present invention is to provide a text management method that allows for

[Means to solve the problem]

The text management method according to the present invention identifies the identity of texts in a text management method that reads text from a text storage file, edits the text, and then stores and manages the edited text in the original text storage file. A text storage file that stores a text identifier including a revision number, update date and time, etc., and reads text from this text storage file into the edit text storage area and family text storage area, and stores the text identifier in the text identifier storage area. a text input means; a text editing means for editing the text in the edited text storage area into edited text; and the original text in the original text storage area and the edited text in the edited text storage area and the text storage file. a difference extraction means for extracting the difference between the two, a difference merging means for merging the two differences extracted by the difference extraction means to obtain a difference merging result, and a difference merging means for extracting the difference between the original text in the original text storage area and the difference merging result. text merging means for merging and creating an edited final text in the edited text storage area;
Compare the text identifier in the text identifier storage area and the text identifier in the text storage file, and if they are the same, store the edited text in the edited text storage area in the text storage file; Using the difference extraction means, the difference between the original text in the original text storage area and the edited text in the edited text storage area and the difference between the original text in the original text storage area and the edited text in the text storage file are determined. After extracting and merging both differences using the difference merging means to obtain a difference merging result, merging the ring text on the original text storage area and the difference merging result using the text merging means. and text output means for creating an edited final text on the edited text storage header and writing the edited final text on the edited text storage area together with a new text a identifier into the text storage file.

[Effect]

In the text management method of the present invention, a text storage file stores text and a text identifier including a revision number, update date and time, etc. for identifying the identity of the text, and a text input means edits text from the text storage file. The text identifier is read into the storage area and the original text storage area, and the text identifier is stored in the text identifier storage area, the text W collection means edits the text in the edited text storage area as an edited text, and the difference extraction means stores the original text. extracting the difference between the ring text on the area and the edited text on the edited text storage area and the text storage file, the difference merging means merging both the differences extracted by the difference extraction means to obtain a difference merging result, The text merging means merges the ring text in the original text storage area and the differential merging result to create an edited final text in the edited text storage area, and the text output means merges the ring text in the original text storage area with the difference merge result, and the text output means merges the text identifier in the text identifier storage area and the text storage file. Compare the above text identifiers, and if they are the same, store the edited text in the edited text storage area in the text storage file, and if they are not the same, use the difference extraction means to edit the text with the ring text in the original text storage area. Extract the difference between the edited text in the text storage area and the ring text in the original text storage area and the edited text in the text storage file, and merge the two differences using a difference merging method to create a difference. After obtaining the merge result, use the text merging means to merge the ring text on the original text storage area and the difference merge result to create an edited final text on the edited text storage area, and then edit the edited text on the edited text storage area. Writes the final text to a text storage file with a new text identifier.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a text management system according to an embodiment of the present invention. The text management system of this embodiment includes a text input means 1, a text collection means 2, a text output means 3, an original text storage area 4, a text identifier storage area 5, an edited text storage area 6, It is composed of a difference extracting means 7, a difference merging means 8, a text merging means 9, and a text storage file 10.

FIG. 2 shows a ring text 202 on the original text storage area 4, an edited text A 201 on the edited text storage area 6, which will be used to explain the text management method of this embodiment.

, the difference B206 between the ring text 202 on the original text storage area 4 and the edited text B2O3 on the text storage file 10, the difference merge result 207 between the difference A204 and the difference B206, and finally the text 3 is a diagram showing an example of the relationship with the edited final text 205 stored in the storage file 10. FIG. Note that “$ALTERm” in FIG. 2 indicates that the following text is to be inserted before the mth line of the ring text 202, and “SA
LTERm,n'' indicates that lines m to n of the ring text 202 are to be deleted and replaced with the following text (if there is no subsequent text, it only indicates deletion. ing).

Referring to FIG. 3, the processing of the text output means 3 includes a text writing request receiving step 301 and a text writing request receiving step 301.

It consists of 7.

Next, the operation of the text management system of this embodiment configured as described above will be explained. In addition, here, user A
An example will be explained in which, while user A is editing the original text 202, user B also edits the same text and replaces it with the edited text B203 in the text storage file 10, and then user A finishes editing and replaces the text. do.

The text editing means 2 is started at the request of the user,
First, the text input means 1 is activated.

When activated by the text editing means 2, the text input means 1 reads the text from the text storage file 10 and a text identifier including a revision number, update date and time, etc. for identifying the identity of the text, and converts the text into the original text. The text identifier is stored in the storage area 4 and the edited text storage area 6, and the text identifier is stored in the text m-warrant storage area 5.

Next, the text a collection means 2 edits the text on the edited text storage area 6 according to the instructions of the user A, and when the editing is completed and the edited text A201 is obtained on the edited text storage area 6. , the text output means 3 is activated in response to an instruction from user A.

When the text output means 3 receives a write request from the text editing means 2 (step 301), the text output means 3 outputs the text identifier in the text identifier storage area 5 and the text storage file 1.
Compare with the text identifier on 0 (step 302)
. If it is determined that the text identifiers are equal, the text output means 3 writes the edited text A201 on the edited text storage area 6 to the text storage file 10 together with the new text identifier (step 307).
, ends the process.

By the way, while user A is editing the original text 202, user B also edits the same text and creates a text storage file lO.
After replacing the above text, the text on the text storage file 10 has changed to the edited text B2O3, so the revision number, update date and time, etc. of the text identifier on the text storage file 10 are determined in step 302. have changed and the text identifiers are determined to be unequal. Therefore, in this case, the text output means 3 cannot directly replace the edited text A201 in the edited text storage area 6 with the edited text B203 in the text storage file IO,
First, the difference extraction means 7 is activated to obtain the difference B206 between the original text 202 and the edited text B2O3 (step 303). Difference with edited text B2O3 B206
Extract.

Next, the text output means 3 activates the difference extraction means 7 again and obtains the difference A204 between the original text 202 and the edited text A201 (step 304), that is,
The difference extraction means 7 extracts the difference A204 between the original text 202 on the original text storage area 4 and the edited text A201 on the edited text storage area 6.

Next, the text output means 3 activates the difference merging means 8 with a higher priority since the difference B206 obtained in step 303 relates to an earlier edit, and the difference A204 is and the difference B206 are merged (step 305).

Specifically, the difference merging means 8 merges the difference A204 and the difference B.
206 is input and merged, and the result is output as a differential merge result 207. At this time, if the difference merging means 8 has an overlapping part between the difference A204 and the difference B206 to be merged (for example, the "$AL" of the difference A204
TER6,6” and the difference B206 “$ALTER6,6
”, or for example, “$ALTER5゜l
O” and “$ALTER9,12” exist, etc.)
, the difference B2 with higher priority (the one edited earlier)
06 is output in the difference merge result 207, and if there is a part of the difference A204 that is not reflected in the difference merge result 207, the part of the difference A204 that is not reflected is output as a warning message to the user. In this way, after reading the text, the same part can be read by another user B.
User B, who had finished editing earlier, issues a warning without actually updating the file if it has been updated.
Editing is not wasted.

Next, the text output means 3 activates the text merging means 9, merges the original text 202 of the original text storage header 4 and the differential merge result 207 obtained in step 305, and creates the edited final text 205. Create it in the edit text storage area 6 (step 306), that is,
The text merging means 9 merges the difference merging result 207 created by the difference merging means 8 and the original text 202, and stores the edited final text 205 in the edited text storage area 6.

Finally, the text output means 3 writes the edited final text 205 on the edited text storage area 6 to the text storage file 10 together with a new text identifier (step 7 307), and ends the process.

〔Effect of the invention〕

As explained above, when replacing text, if another user has rewritten the text after the text was first read, the present invention can replace the text that was originally read and the edited text of each user. By merging the differences between the When editing the text at the same time, there is an effect that the editing can be done without any contradiction as long as different parts of the text are updated.

Also, if another user has updated the same part after reading the text, a warning will be issued without actually updating, so the edits of the user who finished editing first will not be wasted. There is an effect that
