Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distributed editor text receiving system, and more particularly to a distributed editor text receiving system for enabling a terminal side to efficiently edit text in a text file on the host side.

[0002]

2. Description of the Related Art Conventionally, in a distributed editor, the operability of a terminal stand-alone editor is improved by holding as much text as possible to be edited on the terminal side and shortening the transmission time of the text from the host side to the terminal side as much as possible. The following attempts have been made to approach the goodness of.

Method 1 In the online screen editor disclosed in Japanese Patent Laid-Open No. 1-244561, the text is collectively transferred to the terminal side at the start of editing.

Method 2 In the text receiving method of the terminal side editor in the distributed editor disclosed in Japanese Patent Laid-Open No. 2-140864,
When receiving the required text continuously, prepare two buffers to receive the text from the host side,
The text stored in one reception buffer is received in the other reception buffer without waiting for the reception completion notification, and the display on the screen (CRT terminal device) is performed asynchronously with the text reception from the host. So, we are trying to reduce the time for sending text from the host side to the terminal side.

Method 3 In the text management method of the MML editor disclosed in Japanese Patent Laid-Open No. 3-116372, the text for the capacity of the work buffer is stored at the start of editing, and the text which is not in the work buffer is received. To store the text, the edit count that counts the number of edits in each block of the work buffer is referred to, the block with the least edit frequency is found, and the text of that block is returned to the host. The number of text transfers to and from the terminal side is minimized.

[Problems to be solved by the invention]

Each of the above-mentioned three methods has the following drawbacks.

Method 1 Usually, the amount of text stored in one text file on the host side is often large, and sometimes extends to tens of thousands of lines. However, the maximum amount of data that can be sent from the host side to the terminal side in a single transfer is about 20 lines. Therefore, this method can correct only a few places of tens of thousands of lines of text. , At the start of editing, you have to wait while sending the entire text. Therefore, when a plurality of such large-scale files are edited, the editing function is significantly reduced.

Method 2 In this method, while displaying on the screen (CRT terminal device),
Although it attempts to transfer text efficiently, the transfer time is longer than the time it takes to display it on the screen, and the time saved by performing asynchronous reception is short. Furthermore, in this method, when a key is input on the terminal side and editing is performed according to the instruction, the key input request is received after the key input request including the time when the user is thinking while looking at the screen. In the time up to, there is a drawback that text cannot be received.

Method 3 This method is based on the assumption that the work buffer on the terminal side is small, but in the last two years or so, the prices of memory and disk have been reduced, and the terminal side has a considerable amount of text. Became possible. In addition, the disk I / 0 speed has been remarkably increased due to the improved performance of the workstation. Furthermore, it cannot be said that the text returned to the host side using this method is not needed for the next edit. For this reason, it becomes more practical to consider using the memory or disk area on the terminal side to store the text, rather than considering returning the received text as in this method.

The present invention has been made under the above circumstances, and an object thereof is to provide a text receiving system of a distributed editor capable of sending more text from the host side to the terminal side. Another object of the present invention is to provide a text receiving method for a distributed editor that does not wait for text transmission processing from the host side during editing processing.

[0011]

In order to achieve the above object, the text receiving method of the distributed editor according to the present invention stores an input instruction as edit information in an edit information storage area and stores it in the text storage area. An editing device that edits the stored text and outputs the result, creates the editing information storage area and the text storage area at startup, and manages the text stored in the text storage area with the editing device. Includes a text management device that performs asynchronously, further, the text management device, a text receiving means for receiving a fixed amount of text transmitted from the host side, and stores the received text in the text storage area, Based on the edit information stored in the edit information storage area, create edit information for sending and receiving text with the host side. Text management means for, has a configuration and a editing information transmission means for transmitting the editing information created to the host side.

[0012] In another aspect, when the editing device specifies editing processing for the entire text, the editing device waits until the editing start notification is received from the text management device, and the editing start notification is sent from the text management device. If so, only the text in the text storage area is edited, and when this editing work is completed, the text management is notified of that fact, and the text management means stores the editing information stored in the editing information storage area. If the editing process for the entire text is specified, check to see if all the text is stored in the text storage area. If it is not stored, add the editing information for interrupting the text transmission from the host side. , After the storage of the text received from the host side in the text storage area is completed, send an edit start notification to the editing device, When the edit completion notification is received from the collection device, edit information for making the next text request to the host is created, and the edit information transmission means sends the edit request for the entire text to the host side together with other edit requests. Then, the text receiving means determines that the editing process for the entire text on the host side is completed by receiving the next text.

In another aspect, the text management device determines whether the text storage area and the edit information storage area are to be created in the shared memory or on the disk, and the position and size thereof are changed. Area determination means that determines the area and secures the area.

[0014]

According to the present invention, by performing the text receiving process and the editing process asynchronously, more text can be sent from the host side to the terminal side, and the text sending process from the host side during the editing process. I will not wait for you.

Further, according to the present invention, when all the text does not yet exist on the terminal side, even if the processing for the entire text is carried out, the text once transmitted to the terminal side is not invalidated.

Further, according to the present invention, since the equipment of the workstation can be fully utilized by designating the system generation and as much text as possible can be held on the terminal side, it is different from the stand-alone type editor. It is possible to handle large-scale programs on the host side with no operability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing the configuration of a system according to an embodiment of the present invention. In the figure, 10 is an editing device, 4
0 is a text management device.

The editing device 10 stores the instruction from the display / keyboard 60 as editing information in the editing information storage area 20, edits the text stored in the text storage area 30, and displays the result as the display / keyboard. 60 is displayed. Further, when the editing process for the entire text is designated, the editing work is waited until the editing start notification is received from the text management device 40.
Then, if there is an edit start notification from the text management device 40, only the text in the text storage area 30 is edited, and when the editing work is completed, the text management device 40 is notified of that fact.

The text management device 40 has an edit information storage area 20 for temporarily storing edit information sent to the host side so that the edit made on the terminal side can be performed on the host side. The text storage area 30 used by the editing apparatus 10 for editing is created at startup, and the text stored in the text storage area 30 is managed asynchronously with the editing apparatus 10. The text management device 40 includes an edit information transmission unit 41, a text management unit 42, and an area creation unit 43.
And a text receiving means 44.

The edit information sending means 41 sends the edit information to the host side of the distributed editor, and sends an edit request for the entire text to the host side together with other edit requests. The text receiving unit 44 receives a certain amount of text transmitted from the host side, and further determines that the editing process for the entire text on the host side has ended by receiving the next text.

The text management means 42 stores the text obtained from the host side in the text storage area 30 and takes out the editing information stored in the editing information storage area 20 in the order in which the editing was performed, and if necessary, the host The terminal side can be selected by selecting the edit information to be sent to the user side, adding or changing or deleting the edit information for requesting the text, and adding the edit information for interrupting the text transmission from the host side. If the edit processing for the entire text is specified by checking the edit information stored in the edit information storage area 20 so that text that does not yet exist in the host can be efficiently received from the host side, the text storage area 30 Check whether all the texts are stored in, and if not, edit information to interrupt the text transmission from the host side. Addition to, from the end of the storage of the text storage area 30 of the text received from the host,
When the editing start notification is sent to the editing device 10 and the editing end notification is received from the editing device 10, the editing information for making the next text request to the host is created.

The area creating means 43 is a text management device 4
0 refers to SG (system generation) information 50 and refers to the text storage area 30 and the edit information storage area 20.
To make maximum use of the environment such as the memory capacity and disk capacity of the workstation, decide whether to create it in shared memory or on disk, and further change its position and size dynamically. Determine and secure the area.

Next, the operation of the system thus constructed will be described with reference to the flow chart shown in FIG. Here we start a decentralized editor, read the text from the file on the host side, scroll and make some corrections to the desired text, then position the last text of the file, and then the specific character for the whole file. An example will be described in which the columns are collectively replaced.

When the distributed editor is activated (step 201), the editing device 10 is activated (step 21).
Along with 1), the text management device 40 is activated (step 221).

Next, the text management device 40 creates the edit information storage area 20 (step 222) and
The text storage area 30 is created (step 223).
At this time, these areas are created by the area creating means 43.
It is created on a memory or a disk with reference to the SG information 50.

On the other hand, the editing device 10 inputs a key from the display / keyboard 60 (step 21).
2) The edit information is created based on the entered key and stored in the edit information storage area 20 (step 213).

At this time, if the input key is for instructing "read file", the edit information is "read (file information)", "text request (start line position: start, range: end of file). , Direction: ascending order) ”and“ request file information (total number of lines, etc.) ”.

In the text management device 40, the text management means 42 confirms whether or not the edit information is stored in the edit information storage area 20 (step 224), and if the edit information is stored, the edit information transmission means 41 causes the host side. (Step 225). At this time, the text management means 4
2 stores that "text request (start line position: head, range: all, direction: ascending order)" was present in the transmitted edit information.

The host opens the file according to the edit information, and starts transmission of all the texts in a unit of one screen from the file information such as the total number of lines and the leading text. The text reception means 44 receives the text for one screen sent from the host (step 226), the text management means 42 stores the text in the text storage area 30 (step 227), and the edit information storage area 20 is stored again. It is checked (step 224), and if the editing information is not yet stored, the text receiving means 44 receives the text for the next one screen again (step 226).

During this time, the editing device 10 operates in step 213.
The editing information created in step S21 is checked (step 214), the text required for display on the display / keyboard 60 is input from the text storage area 30, and the processing for display is performed (step 215). It is displayed on the keyboard 60 (step 216).

Next, in the editing device 10, step 212
When the key entered in is a scroll request, "Change text display position (line position, column position)" and "Text request (start line position: next line, range: one screen, direction: ascending order) Edit information consisting of "" is stored in the edit information storage area 20 (step 213).

On the other hand, when the text management device 40 inputs this editing information (step 224), the text management means 42 has already sent "text request (start line position:
"Head, range: all, direction: ascending order)" is confirmed to the host, and the edit information is not sent to the host, and text reception processing is performed (step 226).

The editing device 10 inputs the text necessary for displaying on the display 6 from the text storage area 30 (step 214), performs the processing for changing and displaying the cursor position information (step 215), Display on the display / keyboard 60 (step 21)
6).

Further, when the key input in step 212 is "insert one character at cursor position", edit information "insert one character (line position, column position)" is created, and the edit information storage area is created. 20 (step 2)
13). The portion in the text storage area 30 is edited (step 214).

On the other hand, in the text management device 40, if the text management means 42 stores the editing information for instructing the editing of such text, it is input (step 22).
4) The edit information transmitting means 41 transmits the data to the host in the order of accumulation.

If the key entered in step 212 is "positioning request to end of file", the editing device 10 changes "text display position (line position, column position)" and "text request ( Start line position: last line of file, range: one screen, direction: descending order), and the edit information is stored in the edit information storage area 20 (step 213).

On the other hand, when the text management device 40 inputs this editing information in step 224, the start line position for which the text is requested by the text management means 42 does not exist in the text already received. In this case, "text transmission stop" and "text request (start line position: last line of the file, range: one screen, direction: descending order)" are created for the host, and the edit information transmission means 41 is created.
Is transmitted (step 225).

Further, when the key input in step 212 is "request for batch replacement of specific character string for entire file", the editing device 10 displays "character string batch replacement (range: entire file, replacement character string. , Replaced character string) ”, and stores it in the edit information storage area 20 (step 213) and has an instruction from the text management device 40.

On the other hand, when the text management device 40 inputs this editing information in step 224, the text management means 42 confirms that all the texts are not yet stored in the text storage area 30, and edits them. "Cancel text transmission" by the information transmission means 41, and
"String replacement (range: whole file, replacement string,
"Replaced character string)" is transmitted to the host (step 22).
5). In addition, after the text receiving means 44 has transmitted all the text already transmitted from the host,
The text is stored in the text storage area 30 by the text management means 42, and the editing device 10 is instructed to start editing work on the terminal side. When the editing device 10 edits the text in the text storage area 30, the editing device 10 notifies the text management device 40 of the fact.

In the text management device 40, the text management means 42 creates edit information "text request (start line position: line immediately before the last received text, range: all, direction: descending order)". , By the edit information transmitting means 41.

When all the texts have been stored in the text storage area 30 by the text management means 42, the text management device 40 sends "stop text request" to the host.

The present invention is not limited to the above-mentioned embodiments, but can be carried out in various modifications within the scope of its technical idea.
