JPH0488425A - Editing generation control system of text editor - Google Patents

Abstract

PURPOSE:To display an updated part of a text of one image plane in an easy- to-see state with a distinctive color by employing the editing generation control system which can decide whether or not the text is edited in character string units for the text editor. CONSTITUTION:A text file 10 is inputted from a file input/output means 8 and stored in a text storage area 5 through a text control means 7. Further, a display means 3 inputs and displays the text by using a text control means 7. Further, information which is inputted from a terminal 1 by an input means 2 is stored by a text editing means 6 and stored as update information in the text storage area 5 by using a generation control means 4 to update the display text, and a text is inputted by using the display means 3 or text control means 7, updated with the update information inputted by using the generation control means 4, and displayed. Further, a file input/output means 8 uses the text control means 7 to input a text, which is updated with update information inputted by using the generation control means 4, thereby outputting the result to the file. Consequently, an easy-to-see display is made.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an execution method of a text editor, which is used for the longest time in a TSS system, and particularly relates to a method for executing a text editor, which is used for a long time in a TSS system, and in particular, a text editor that manages how text is edited by a text editor. Concerning an editing generation management method in an editor.

[Conventional technology]

Conventionally, the editing generation management method in this type of text editor has been a method in which a generation management means is added to the beginning of each line and management is performed on a line-by-line basis.

[Problem to be solved by the invention]

The conventional edit generation management method described above manages line by line, so even if you know which line has been edited, you have to silently compare old and new records to see which string has been edited. Furthermore, there is a drawback that even if only one character in one line is changed, an area for one line is required.

[Means to solve the problem]

The editing generation management method in the text editor of the present invention includes an input means that receives key input from a terminal, and a text that receives key information from the input means, creates update information consisting of a type and a character string, and sends it to the generation management means. an editing means; a generation management means having a function of adding updated information passed from the text editing means to each record in the text storage area; and a function of referencing the updated information in the text storage area; and updating text in the text storage area. a text management means that uses the text management means to refer to the text and uses a generation management means to display changed parts on a terminal in a format that can be distinguished from the original text; A function that inputs text from a file and stores it in a text storage area using a text management means, and updates the text retrieved from the text storage area by the text management means with update information retrieved by a generation management means, and outputs the edited text. It has a file input/output means with a function of writing to a file.

〔Example〕

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

FIG. 1 shows an embodiment of the invention. In FIG. 1, an editing generation management system in a text editor which is an embodiment of the present invention includes an input means 2, a display means 3, a generation management means 4
, a text editor 9 consisting of a text storage area 5, a text editing means 6, a text management means 7, and a file input/output means 8, a terminal 1, and a text file 10.

FIG. 2 is a flowchart for explaining the overall operation of the text editor that employs the editing generation management method. In FIG. 2, in the text input process (step 21), a text file 10 is input by the file input/output means 8 and stored in the text storage area 5 via the text management means 7. To display the text stored in the text storage area 5 (step 22), the display means 3 uses the text management means 7 to input and display the text. The display text is updated (step 23) by the text editing means 6 accumulating the information input from the terminal 1 through the input means 2 and storing it as update information in the text storage area 5 using the generation management means 4. .

The process of displaying the updated text (step 24) involves inputting text using the display means 3 or text management means 7, and updating the text with update information input using the generation management means 4. indicate. text storage area 5
The process of outputting the updated text to a file (step 25) involves the file input/output means 8 inputting a text using the text management means 7, and inputting the update information input into the text using the generation management means 4. This is done by updating the file and outputting the result to a file.

FIG. 3 shows the format of records stored in the text storage area 5. In FIG. 3, each record has the original text length 31 and its text image 32 at the beginning, and if the record has been updated, update information 33 is added at the end. The update information 33 has an update type 34 of insertion (I), replacement (R), and deletion (D).
It is composed of the digit position 35 where the update was performed, the length 36, and an image 37 of the updated character string excluding deletions.

FIG. 4 is a flowchart showing the processing of the display means 3 when displaying updated text. In FIG. 4, the text management means 7 is used to enter the original text and set the color to green (step 41). Update information is input using the generation management means 4 (step 42). If the edit type of the update information is ■ (step 44), the text after the edit column position is shifted by the editor length, the updated character string is inserted there, and the color of that part is set to blue (step 45). In the case of replacement (step 46), overwrite the original text with the updated string and change the color of that part to yellow (step 47).
. In the case of deletion (step 47), the text after the editing digit position is shifted forward by the editor length and the color is set to red by one digit (step 49). Processing of 0 or more is repeated until there is no update processing (step 43). , if there is no more updated information, the entire text is displayed on the screen (step 50). By repeating the above process several times on the screen, the display means 3 displays the
Not only can the updated text on a screen be displayed in different colors for easy viewing, but also the specified part can be easily restored to its original state.

〔Effect of the invention〕

As explained above, the present invention employs an editing generation management method in a text editor that can determine whether or not each character string has been edited, thereby making it possible to clearly identify edited parts in each character string. At the same time, generation information can also be reduced compared to row-by-row management.
