DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus suitable for creating a document having a complicated format such as a newspaper.

[0002]

2. Description of the Related Art In a document creation device such as a Japanese document creation device or a workstation, a rectangular block is generated by a format mark, and character data can be input to documents having various layouts.

[0003] For example, as shown in the document format diagram of FIG. 7, tables (R1) and (R2) created in a key line format are generated on a document text (T). Depending on the format, a rectangular block (B1),
(B2) and (B3) are generated, and the rectangular block (B
Documents in various formats, such as inputting character data in (1), (B2), and (B3), can be created.

[0004]

However, in the conventional document creation apparatus, rectangular blocks (B1),
(B2) and (B3), if the left and right block format column positions are different, even if the document is actually continuous, it will be treated as a separate block. The character editing process needs to be performed separately for each block, and editing the document is very time-consuming.

The document creating apparatus of the present invention has been made in view of such circumstances, and performs editing processing by successively treating rectangular blocks in contact with each other in a document, thereby enabling a smooth editing processing. The purpose is to provide.

In the case where the editing process is performed by successively treating rectangular blocks adjacent to each other, in the case of a document having a format as shown in FIG. 7, one rectangular block into which character data overflowing from the rectangular block flows next. However, in a document having a format as shown in the format configuration diagram of FIG. 8, the rectangular block (B1) is replaced with the rectangular blocks (B2) and (B
A plurality of rectangular blocks referred to as 3) are in contact with each other. In such a case, the number of rectangular blocks into which character data overflowing from the rectangular block (B1) flows next is not determined.
In addition, since the character data overflowing from the rectangular blocks (B2) and (B3) both flow into the rectangular block (B4), there is a problem that the character data is destroyed.

The document creating apparatus of the present invention also solves the above-described problem that arises when editing processing is performed by successively handling rectangular blocks that are in contact with each other.

[0008]

SUMMARY OF THE INVENTION A document creation apparatus according to the present invention includes a plurality of lines of document text, in which format marks such as ruled lines, indents, and margins and character data are mixed. In a document creation apparatus that performs editing processing such as insertion or deletion, a first block having a character data inputtable text formed by the format mark in another line and another line continuous with the line in an arbitrary line A block for retrieving a second block formed by the format mark including a text in which character data can be input most widely from a left format column position to a right format column position of the first block. Search means,
In the second block searched by the block search means, the block search is similarly performed on a line including the first block, and the left format column position to the right format column position of the second block are changed. A search is made for a third block formed by the above-mentioned format mark including a text in which character data can be input most widely, and if the first block and the third block are the same block, the first block is searched. Block and the second block are determined to be continuous blocks, and the block continuation determining unit determines in the character data editing process that the blocks adjacent to each other are continuous. Comprises editing processing means for continuing processing to the adjacent block, and terminating the editing process when the adjacent block is determined to be discontinuous.

[0009]

The block continuity determining means performs continuity determination between a plurality of rectangular blocks and performs an editing process based on the result, so that a character editing operation of a document having a complicated format can be performed without breaking the document. , Operability and processing speed can be improved.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 is an overall configuration diagram showing an embodiment of a document creation apparatus according to the present invention.

In FIG. 1, reference numeral 1 denotes an input unit having keys such as a cursor movement key, a character insertion key, a character deletion key, and a memory call key. (2) is a cursor counter, which is operated by a cursor movement instruction from the input unit (1).
Count the cursor position. (3) is a control unit, (4)
Is a text buffer, and (5) is a one-line buffer (line buffer), in which arbitrary line data in the text buffer (4) is stored in an editable form. (6) is a one-character data READ part, (7) is a one-character data WRITE part, (8) is a one-character buffer,
For one line buffer (5), R /
W (READ / WRITE). An editing unit (9) performs an editing process corresponding to a function key of the input unit (1). (10) is a text management unit, which manages the text buffer (4) by the editing unit (9). (11) is a continuous block analysis unit that analyzes the continuity of the specified block and the blocks before and after the specified block. (12) is an output unit such as a CRT.

Next, the internal processing of the continuous block analysis unit (11) will be described with reference to the specific examples shown in the document structure diagrams of FIGS. 2A and 2B and the flowchart shown in FIG. .

I. Analysis processing of a rectangular block (C block (first block)) continuous to the rectangular block (C block (first block)) at the position of the cursor (c) in the rectangular block format sequence shown in FIG.

First, the line data at the designated cursor position (Nth line) is called into the one-line buffer (5) (STEP 1).
1).

The format column position of the block including the designated X column position is searched from the data of the one-line buffer (5), and set to the position variables (LC1, RC1) (STEP).
2). The column positions indicated by the position variables (LC1, RC1) are as shown in the figure.

Next, data of the next M-th row (M-th row = N-th row + 1) for analyzing the continuation of blocks is called into the one-row buffer (5) (STEP 3).

In the data of the one-line buffer (5), a block containing the widest text data is searched for from the position variable (LC1) to the position variable (RC1), and the block containing the text data is searched for in the position variable (LC2, RC2). A format column position is set (STEP 4). From the position variable (LC1) to the position variable (RC1), the block containing the widest text data is the A block (second block), and the column position indicated by the position variables (LC2, RC2) is shown in FIG. Looks like The B block has a wider block width than the A block, but the block width overlapping between the position variable (LC1) and the position variable (RC1) is smaller than the A block, and is therefore out of scope.

When the position variables (LC2, RC2) are set, the N-th row data is called again to the one-row buffer (STEP 5).

Next, in the data of the one-line buffer (5), between the position variable (LC2) and the position variable (RC2),
A block including the widest text data is searched, and a block format column position is set in a position variable (LC3, RC3) (STEP 6). Position variables (LC3, RC3)
Are as shown in the figure.

Here, the position variables (LC1, RC1) and the position variables (LC3, RC3) are compared, and if they are the same block, the block (first block) indicated by the position variables (LC1, RC1) and the position variable (LC2) , RC2) are assumed to be continuous, and if different blocks, the block indicated by the position variables (LC1, RC1) and the block indicated by the position variables (LC2, RC2) are continuous. Assuming that there is no data (STEP 7), the process ends. In the figure, the block (block C) indicated by the position variables (LC1, RC1) and the block (block C) indicated by the position variables (LC3, RC3) are the same, so that the C block is continuous with the A block. It is determined that there is.

II. Analysis of a rectangular block (C block (first block)) that is continuous with the rectangular block (C block (first block)) at the position of the cursor (c) in the rectangular block format sequence shown in FIG.

By proceeding based on the flowchart of FIG. 3, the position variables (LC1, RC1), the position variables (LC2, RC2), and the position variables (LC3.RC3) are as shown in the figure. Where the position variables (LC1, RC1)
(First block) and a position variable (LC
Since the block (third block) indicated by (3, RC3) is a different block, there is no block continuous with the C block.

Next, a description will be given of the flow of processing when editing processing for inserting and deleting characters in the document creation apparatus of the present invention with reference to the flowchart shown in FIG.

First, position variables (L1, C1) as text data READ pointers and text data WRI
Position variables (L2, C2) are given as TE pointers (STEP 10). Here, the position variables (L1, C1) <
If the relationship is the position variable (L2, C2), it indicates an insertion process, and the position variable (L1, C1)> position variable (L2, C2)
If the relationship is, this indicates a deletion process.

Next, it is determined whether the character data at the position of the position variable (L1, C1) is a format mark (STEP 1).
1).

If it is a format mark, [Process 1] is executed (STEP 12). The contents of [Process 1] will be described later.

If it is not a format mark, the position variable (L
The character data at the position of (1, C1) is read from the read one-line buffer (5) to the one-character buffer (8) (S
TEP13).

Next, it is determined whether the character data at the position of the position variable (L2, C2) is a format mark (STEP 1).
4).

If it is a format mark, [Process 1] is executed (STEP 15).

If it is not a format mark, 1 for WRITE
1 is added to the position of the position variable (L2, C2) in the row buffer (5).
Write the characters in the character buffer (8) (STE
P16).

Next, column position variables (C1) and (C2)
Is counted by 1 (STEP17, STEP18), and S
Returning to the TEP 11, by repeating this process, insertion and deletion of character data in a block can be performed.

Next, [Process 1] executed in STEP 12 and STEP 15 will be described with reference to the flowchart shown in FIG.

First, since the position variable (LX1, CX1) sent as a parameter is on a format mark, a rectangular block on the next line following the rectangular block having this format mark as the right format is searched (STEP 101). ). This search is processed based on the flow of the flowchart in FIG.

In STEP 102, if there is no continuous block, the process proceeds to STEP 103 [processing 2].
Execute [Process 2] will be described later.

If there is a continuous block in STEP 102, the transition position variable (L
X1, CX1) is set to the start position of the continuous rectangular block, and the process exits from [Process 1] and proceeds from STEP 11 to STE
The process returns to P14 (STEP 105).

Next, [Process 2] in STEP 103 will be described with reference to the flowchart of FIG.

If there is no continuous block, and if there is no continuous block for text data READ, the flow shifts to STEP 201, and [processing 2] assumes that the text WR is executed during the processing of the character deletion function.
The text data from the position of the ITE pointer to the position of the text READ pointer is rewritten (deleted) with null data (STEP 202), and the process ends.

If there is no continuous block, and if there is no continuous block for text data WRITE, the flow shifts to STEP 203, and [processing 2] is executed during the processing of the character insertion function. Still RE
WRITE the character data that can be added to the character memory buffer until the data cannot be read (STEP 20).
4), end the process.

By this processing, the operator can call the overflow data by the character insertion function to an arbitrary place by the memory calling function or the like.
