Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character string editing apparatus, and provides an environment for character string editing such as a so-called workbench for program development.

[0002]

2. Description of the Related Art In order to improve the efficiency of program development, how to reduce bugs becomes a problem. And
In developing a program, one of the conditions is that there is no error in the character string input as a program in order to reduce bugs.

In this respect, conventionally, a reserved word as a programming language is verified by referring to a standard grammar for each programming language. On the other hand, a character string such as a variable is arbitrarily defined by a programmer as a list of meaningless characters, so that it is virtually impossible to prepare a dictionary or the like in advance to verify spelling.

Therefore, it is necessary to visually check the mistake of the program or to find it through the compiler. A dedicated system has been developed for the purpose of grammar verification, but it is not much different from debugging with a compiler.

As a program development support tool, for example, Microsoft CVer. PW of 6.0
B (programmer's workbench) and the workbench of Quick C of Microsoft are also provided.

[0006] With these tools, once a character string is input, and once a program is completed, debugging is performed while compiling on the editor screen, showing lines with bugs, and showing the programmer a syntax error. Issue a warning such as. The programmer corrects the mistake indicated by the warning and recompiles to see if it was debugged.

[0007]

Such a tool has the advantage that it can be compiled from the editor screen, and has the advantage that it is easier to correct the bug portion compared to the case where it is not. However, since the debugging is basically a compilation, the program cannot be verified until the program is completed in a tentative unit. Therefore, the longer the program, the harder it is to debug
There was a problem that hindered rapid program development.

The present invention has been made in view of the above points, and it is an object of the present invention to enable verification of a program before the completion of the program, and more specifically, a character string. It is an object of the present invention to provide a versatile character string editing device that improves time efficiency by automatically verifying a character string during editing and is compatible with different programming languages.

[0009]

The present invention takes the following means in order to solve the above-mentioned problems. That is, the character string editing device of the present invention, as shown in the principle diagram of FIG.
(a) input means 10, (b) character buffer 12, (c) display means 14, (d) file editing means 16, (e) table 18 having reference character string registration unit 38, (f) character string comparison means Two
0, (g) display changing means 22 is provided.

The input means 10 is, for example, a keyboard 6
8. An input unit for inputting a character string, such as a handwriting input pad. The character buffer 12 is a storage unit that stores the character string input by the input unit 10.

The display means 14 is a display such as a CRT display 70 or a liquid crystal display for displaying the character string stored in the character buffer 12, or a display device such as a printer.

The file editing means 16 is an editor for editing the input character string as a file. The table 18 is composed of a storage device and constitutes a table having a reference character string registration unit 38 for registering a reference character string for comparison.

As the table 18, it is desirable to have a user table 24 that can be freely rewritten by the user, that is, a user table 24. Further, it is desirable that the table 18 is constructed so that the reference character string is divided according to its attribute and registered. For example, reference character strings such as AAA, BBB, and CCC are stored corresponding to the attribute of reserved word, and P corresponding to the attribute of variable is stored.
The attribute-reference character string is associated with the reference character strings such as PPP, QQQQ, and RRRR. The number of tables 18 can be configured such that a plurality of tables are provided for each attribute, but one table is divided for each attribute and the reference character string is stored for each attribute. Is also possible. The point is that the reference character string should be registered according to its attribute.

Although there are various attributes of the reference character string, in the case of a character string defined as a programming language, as described above, in addition to reserved words, variables, etc., operators, control character strings,
There are attributes such as constants, identifiers, symbols, data types, and so on. It is also possible to classify by an attribute of a character string that newly appears during editing.

The character string comparison means 20 compares the character string input by the input means 10 with a reference character string registered in the table 18. The display changing unit 22 changes the display form of the character string on the display unit 14 when the character string comparing unit 20 determines that the input character string is not the same as the reference character string.

The change of the display form means the conversion from the normal display form to the emphasized character with a thick line, and when the normal display is the Gothic type, the display form is returned to another font such as italic type or Mincho type. That is, the character string is displayed in reverse video, the character string is underlined, and the character string is shaded so that the display format is different from the normal character string display.

Information about what kind of display format should be used for a certain attribute can be predetermined on the program according to the attribute of the table and the information on whether it is a new character string. It is also possible to provide a display format registration unit 32 in the table 18 and register the display format there.

As the table 18, automatic rewriting means 19
An automatic rewrite table 26 that is automatically rewritten by This table also includes an attribute unit 28, a character string registration unit 30, and a display format registration unit 32 as necessary.
Such a table is used as a new character string registration table, and a new character string is set as an attribute. When the character string comparing means 20 determines that the input character string is a character string other than the reference character string registered in the reference character string registering unit 38, the automatic rewriting means 19 causes the reference character string to be changed. The character strings other than the columns are registered in the character string registration unit 30 of the new character string registration table. At this time, the display changing unit 22 displays the character string registered in the new character string registration unit 34 on the display unit 14 according to the display format determined by the program or the like and displays the newly appearing character string. Change the display format to indicate that it is a column.
Spelling mistakes are included in the character string that appears as a new character string. When a correction input is made, such a character string to be corrected is replaced with the corrected character string and registered.

The automatic rewriting table 26 may be provided with an already-existing character string registration unit 36 in addition to the new character string registration unit 34.
In the already-existing character string registration unit 36, the new character string registered in the new character string registration unit 34 is not the new character string when the file is edited for the second time. Therefore, the new character string registration unit 34
It is necessary to move the new character string registered in the above to the already-existing character string registration unit 36. The already-existing character string registration unit 36 is an area for this purpose. The character string registered in the new character string registration unit 34 is transferred to the already-existing character string registration unit 36 when the file editing means 16 is activated or terminated.

The character string is verified after the input of at least one character string is completed. As a verification start condition, it is preferable that the input means 10 includes a character string confirmation key 78 indicating completion of input of a character string, and the input of the character string confirmation key 78 is waited for to be a condition for starting character string verification. ..

When the input means 10 is the keyboard 68, the character string confirmation key 78 is a CR key, an ESC key, a space key, an XFER key, or a CTRL key + G.
Keys, CTRL key + GRPH key + H key and the like can be exemplified, but any input may be used as long as it is agreed that the character string is confirmed by a predetermined input.

When the character string confirming key 78 is input, the character string comparing means 20 starts the comparison between the character string and the reference character string, assuming that the input of the character string is completed. However, if the input from the character string confirmation key 78 is, for example, 10
The verification start time may be controlled such that the verification is started when there is a turn.

In a most preferred aspect of the present invention, the table registers the reference character strings by classifying them according to their attributes, and the comparison of the input character strings by the character string comparing means 20 is performed by the character strings. The confirmation key 78 is input as a start condition, and it is performed for each attribute of the reference character string in the table. The automatic rewriting unit 19 determines whether the input character string is the result of the comparison by the character string comparing unit 20. When the input character string does not match the reference character string of, the input character string is registered in the new character string registration unit 34 indicating that it is a newly appearing character string,
When the input character string matches the reference character string as a result of the comparison by the character string comparing unit 20, the display changing unit 22 changes the display format for each attribute of the matched reference character string, and the display unit 14 On the other hand, when the input character string does not match any of the reference character strings, the character string editing device outputs the character string to the display means 14 in a display format indicating that the character string is a newly appearing character string.

[0024]

When a program is created by the editing apparatus of the present invention, the following is done. When creating a program, a character string necessary for realizing a desired process is input from the input means 10 according to the grammar specific to the programming language. The character string input from the input means 10 is stored in the character buffer 12 and displayed on the CRT display 70 as the display means 14, for example. The input character string is edited as a file by the file editing means 16.

When at least one character string is input during the editing, the character string confirmation key 78 is input, and the verification of the character string is started. Verification will be performed in the subsequent processing.

Search the table to find the character buffer 1
Compare the string in 2 with the reference string in the table. If there is a matching character string, it is understood that it is not an error in the programming language, so there is no need to change the display format of the character string by the display changing means 22 and display it on the display means 14. However, when the attribute and the reference character string are registered in the table in contrast with each other, when there is a matching character string, the display format of the character string is changed by the display changing means 22 for each attribute. When displayed on the display means 14,
You can determine which attribute the input string is in.

When there is no corresponding character string in the table, the character string in the character buffer 12 can be registered in the table as a new character string and can be displayed on the display unit 14 in a format that can be recognized as a new character string. Is.

Regarding the above, for example, a case where the table is divided into a table for registering reserved words and the like and a table for registering a newly appearing character string will be described. First, if there is a reference character string that matches the input character string in the table for registering reserved words and the like, it is displayed on the display means 14 in such a format that the character string exists in this table. If the reference character string that matches the input character string does not exist in the table for registering reserved words, search the table for newly appearing character strings, and if there is the same character string, edit it until the last time during editing. Since it is determined that the character string has appeared, the character string is displayed on the display unit 14 in a format that can be understood. Then, if there is no corresponding character string in the table, the character string in the character buffer 12 is registered in the table as a new character string, and is displayed on the display means 14 in a format that can be recognized as a new character string.

For example, in editing a programming language source program, when a user registers a reserved word in the programming language in the table 24 and activates the editing device, the reserved word is in lower case and the character strings of other variables are in upper case. Shall be written in writing.

In this case, when a certain character string in the file is changed or added and a key other than alphanumeric characters is pressed, 1
It is considered that the input of one character string is completed, the table 24 is searched, and if it corresponds to a reserved word, it is converted to, for example, a lowercase character, and the user can confirm that the input character string is a reserved word. Furthermore, if there is no corresponding character string in the table 24, the table 26 is searched, and if there is a matching character string, it is converted to, for example, uppercase, and the user can confirm that the character string has already been issued. Further, if it is not in the table 26, for example, it is displayed in capital letters with high brightness, and if a previously entered character string is erroneously input, the user can confirm that there is a misspelling and correct it immediately.

Since such verification is performed every time the character string confirmation key 78 is input, the character string can be verified in real time while the character string is being edited. The present invention is intended as a character string editing device for supporting the development of a program, but its application range is generally applicable when dealing with character strings. For example, it can be applied to an editor for character string editing, spell check in an English word processor, and the like. In a conventional English word processor, the spell check function is activated to check spelling, but according to the present invention, spell check can be performed in real time every time a character string is input.

Input / output in each of these sections is performed by an input / output processing program (basic) executed by the central processing unit 50.
input / output sysytem), commonly known as BIOS. The file editing unit 16 is configured on the central processing unit 50. A register in the central processing unit 50 constitutes a character buffer 12 that stores a character string to be edited. In this file editing unit 16,
A character string comparison unit 20, a display change instruction unit 22, and an automatic rewriting unit 19 are provided.

Each section will be described in detail below. The keyboard 68 has a key arrangement according to the JIS standard, and a return key (CR key) is set as a character string confirmation key 78 indicating completion of input of a character string. A space key may be set as the character string confirmation key 78, or the operator may set it freely. Keyboard 6
When the 8 key is pressed, the key code data according to the arrangement order of the keys is generated. When the keyboard 68 generates data, a hardware interrupt occurs and the BIOS
Control is transferred to S.

The read only memory (ROM) 54
Is provided with a conversion table 82 in which so-called key codes and ASCII codes are associated with each other. Keyboard 68
When the key code is generated by pressing down, the key data (ASCII code) is referred to with reference to the conversion table 82.
And create the character buffer 12 with the key code.
It is stored in (ring buffer).

The random access memory (RAM) includes
As shown in FIGS. 3 and 4, the user table 24, in which the user can arbitrarily set the contents, and the file editing unit 16
And an automatic rewriting table 26 are formed. Each table is provided with an attribute section 28, a character string registration section 30, and a display format registration section 32. This display format registration unit 32
Alternatively, the display format specified in advance by the program may be specified without referring to the attribute of the character string. In that case, the display format registration section is deleted from FIGS. Note that the attribute, the character string registration unit, and the display format have a correspondence relationship.
The display format registration unit 32 registers the display format of the character string registered in the character string registration unit 30. This display format differs for each attribute of the character string. The contents of the display format registration unit 32 can be arbitrarily set by the user on the program.

Character string registration section 3 of user table 24
As shown in FIG. 3, for example, reserved words (keywords) and variables of programming languages are registered in advance in 0 as shown in FIG. For example, the reserved word in C language is auto
o, break, case, char, const, c
ontinue, default, do, doubl
e, else, enum, extern, float,
for, goto, if, int, long, regi
star, return, short, sizeof,
static, struct, switch, type
def, union, unsigned, void, w
such as hile.

In the display format registration section 32 of the user table 24, an arbitrary display format is selected and registered as a display format representing a reserved word, such as underline, halftone dot, emphasized character, and font change. If you choose to change the font,
Refer to the font table and set which font to use.

In the C language, the programmer can set variables arbitrarily. For example, as variables, i, n, m, or aa
Register a, bbb, hensu, etc. Specify any display format as the display format that indicates the variable. The symbol,
A character string consisting only of operators and numbers does not really make much sense as a check target.

As shown in FIG. 4, the automatic rewriting table 26 has a new character string registration unit 34 and an already-existing character string registration unit 36. The new character string registration unit 34 uses the automatic rewriting means 19
Is an area for writing a new character string when the character string is a new character string. Also, the new character string registration unit 3
A display format registration unit 32 corresponding to No. 4 is provided. The already-existing character string registration unit 36 is an area for registering already-existing character strings. When the file editing unit 16 is activated or terminated, the contents of the new character string registration unit 34 are transferred to the already-existing character string registration unit 36.

The CRT controller 62 uses the text V
Takes out the text data stored in the RAM 60 and CRs
It is displayed on the T display 70. When the font is specified, ASCII code in the text VRAM60,
The phantom pattern corresponding to the alphanumeric kana code and the Japanese code is read into the font pattern buffer, and the font pattern is transferred to the graphic VRAM 64 and displayed on the CRT display 70.

The text VRAM 60 is provided with an attribute area 76. The attribute area 76 is a register which stores 8-bit character string decoration information (attribute data). In accordance with this attribute data, the character string is underlined or shaded.

The character string comparison unit 20 compares the character string input from the keyboard 68 with the reference character string registered in the table 18. For example, when “auto” is input, the table is searched by the command of the character string comparison unit 20. Data of each table and character buffer 1
By comparing with the key data of No. 2, it can be seen that the attribute of auto is a reserved word and its display format is underlined.

When the input character string does not exist in any of the tables, the attribute is found to be a new character string. Therefore, the character string registration unit 30 of the attribute "new character string" of the automatic rewriting table 26 is set. It will be newly registered.

The display changing unit gives an instruction to change the display format of the character string displayed on the CRT display 70. Normally, the character string is displayed on the CRT display 70 in the standard display format (Gothic type). Then, when the character string confirmation key 78 is pressed, the display format registration unit 32 of each table is referred to, and the display format of the character string on the CRT display 70 is changed according to the display format information corresponding to the attribute of the character string. ..

That is, for example, when auto is input, as described above, the attribute of auto is a reserved word,
It can be seen that the display format is underlined. At this time, the data indicating the underline is the text VRA.
It is stored in the attribute area 76 of the M60, and the CRT controller 62 stores the C in accordance with the attribute information.
Underline the auto on the RT screen.

When the input character string does not exist in any of the tables, the attribute is a new character string, and the new character string is newly registered in the character string registration unit 30 by the automatic rewriting means 19. Then, the display format registration unit 32 corresponding to the attribute is referred to. Here, since the shading is registered, the data indicating the shading is the text VR.
It is stored in the attribute area 76 of the AM 60. According to this attribute information, the CRT controller 62
Shades the new character string on the CRT screen.

When the file is closed and edited again,
The character string registered as the new character string at the previous editing is transferred to the already-existing character string registration unit 36. Therefore, the new character string registration unit 34 is in the initialized state.

Each time the character string determination key 78 is pressed, the contents of the previously registered new character string registration unit 34 are transferred to the already-existing character string registration unit 36, and the new character string registration unit 34 is initialized. You can

The above is the configuration of the present embodiment, and this configuration corresponds to the configuration of the present invention as follows. (a) Input means 10 ... Keyboard 68 (b) Character buffer 12 ... Character buffer 12 (c) Display means 14 ... CRT display 7
0 (d) Table 18 ... RAM 56 (24, 2)
6) (e) Character string comparing means 20 ... Character string comparing section 20 in the file editing section 16 (f) Display changing means 22 ... Display change instructing section 22 in the file editing section 16 and attributes of the text VRAM Area 76 Hereinafter, an example of program editing processing according to the present embodiment will be described. <Processing Example 1> Processing example 1 will be described with reference to the flowchart of FIG.

In this processing example, every time the character string confirmation key 78 is pressed, the contents of the previously registered new character string registration unit 34 are transferred to the already-existing character string registration unit 36, and the new character string registration unit 34 is initialized. I tried to turn it on.

First, a keyboard 68 as an input device,
Alternatively, the input from the file is added to the buffer (step 100). Then, it is judged whether or not the confirm key has been pressed (step 101). If the confirm key has not been pressed, step 100 is repeated. When the enter key is pressed, the process proceeds to step 102.

In step 102, the character string in the edited character buffer is retrieved from the table 24, and the character string comparison unit 20
However, the character string in the character buffer 12 and the contents of the user table 24 are compared (step 103).

Then, if there is a matching reference character string, the information of the display format registration section 32 corresponding to the attribute of the reference character string is taken into the attribute area 76 by the instruction of the display changing section, and the CRT controller 62. Then, the display format is changed and displayed on the CRT display 70 (step 104).

If the input character string does not exist in the user table 24, the character string in the edit character buffer is searched from the automatic rewriting table 26 in step 105. If the reference character string that matches the input character string exists in the already-existing character string registration unit 36 of the automatic rewriting table 26 (step 106), the display format information corresponding to the attribute of the reference character string is attributed by the instruction of the display changing unit. It is taken into the area 76, and the CRT controller 62 changes the display format and displays it on the CRT display 70 (step 107).

When it is determined in step 106 that the reference character string that matches the input character string does not exist in the automatic rewriting table 26, the input character string is registered in the new character string registration unit 34 and is an attribute that the character string is a new character string. The display format information corresponding to the
And is displayed on the CRT display 70 in a different display format by the CRT controller 62 (step 108).

When the same character string as the character string registered in the new character string registration unit 34 is input, the previous character string has already been transferred to the already-existing character string registration unit 36 and is therefore displayed as the already-existing character string. To be done.

The above processing is performed every time the character string confirmation key 78 is pressed. Therefore, the user can grasp the attribute of the input character string from the display format in real time every time the character string is input. In particular, when the input character string is a new character string, some error is expected to exist, so that the programmer can be encouraged to debug. <Processing Example 2> In the processing example 2, for example, a character string in C language as shown in FIG. 6 is input. This program is a program for obtaining the total of the numbers 1 to n. In addition, prior to editing, reserved words in C language, preprocessor instructions that you intend to use in the program,
Register the function in advance. Symbols are not subject to processing. In addition, character strings that consist only of numbers, character strings that start with numbers, and full-width Japanese character strings are not processed. Reserved words, preprocessor instructions, functions, control characters, format sequences are underlined, new characters are bold, and others are normally displayed.

After the file editing unit 16 is activated, a desired program is entered from the keyboard 68 and described. To edit the program in Figure 6,
When a character string is input from the keyboard 68, the following processing is performed.

First, / * is input. The key data indicating the input character string is stored in the character buffer as described above. Next, when the CR key is pressed, the input character string is confirmed,
The character string comparison unit 20 is activated to determine whether or not data indicating / * exists in the table. / * Is a symbol and not a target of processing, so it is displayed in the normal display.

Next, the "cumulative program" is input and CR is entered.
The key is pressed. This character string is also not processed and is displayed in the normal format on the CRT. Hereinafter, the description of the character string that is not the processing target will be omitted.

When include is input, since this is a preprocessor instruction, the display format information = “underline” is indexed from the attribute data, and the data indicating the underline is stored in the attribute area 76 of the text VRAM 60. To be done. According to this attribute information, the CRT controller 62 underlines the character string "include" on the CRT screen.
Other character strings are also compared with the registered contents in the table in the same manner as above, and displayed in a predetermined display format according to the corresponding attribute. The modes are as shown in Table 1 below.

[0063]

[Table 1]

From the correspondence relationship in Table 1, the program is displayed on the CRT display 70 as shown in FIG. In this program, if you should type the function printf but misspell it as frontf,
Since the standard character of frontf is not registered in the table corresponding to the function, the frontf is registered as a new character string in the new character string registration unit 34 and displayed as a bold character. Depending on the display format, the programmer
Know that ntf is a new appearance. It's strange for a new string to appear like this, so the programmer notices some spelling mistakes. Therefore,
When the printf is rewritten to the printf and the character string confirmation key 78 is pressed, the user table 24 is searched again. This second search reveals that printf is a function. At the same time, pro of the new character string registration unit 34
The ntf is also rewritten and then transferred to the already-existing character string registration unit 36, but since it has already been registered in the user table 24, it is deleted from the already-existing character string registration unit 36.

As described above, since the display format can be changed and displayed for each attribute, the type of character string can be visually recognized. As a result, if the input character string is a new character string, it is presumed that there is some error such as a spelling error in the new character string.

If the new character string is rewritten after the incorrect new character string is rewritten, the registration is corrected with the contents after the rewriting. Also, if there is a character string that matches the reference character string in the table, it is understood that it is not an error in the programming language.

[0067]

According to the present invention, an error such as a misspelling or a character string which is not in the programming language can be confirmed during the character string editing, and an accurate character string editing operation can be performed. In particular, when used for program editing, it is possible to edit a program with few bugs without compiling.
