Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program including parentheses, or an information processing apparatus for displaying a sentence.

[0002]

2. Description of the Related Art Conventionally, when a program including parentheses or a sentence is displayed on the screen of an information processing device, an input person (hereinafter referred to as a user) of the information processing device inputs a character code by a key of a keyboard. FIG. 3 shows a schematic configuration diagram of such an information processing apparatus.

In FIG. 3, reference numeral 1 denotes an input means including a keyboard in which keys are arranged in association with characters and the like, insertion, deletion, cursor movement, etc., and a character code, or Control code is entered. Reference numeral 2 is a character code input from the input means 1, or an input register for sequentially storing a control code, and 3 is a character code sent from the input register 2 as a character string code via the edit control means 4 described later. Memory to store,
4 is sent to the memory 3 when the code stored in the input register 2 is a character code, and stored in the memory 3 when the code stored in the input register 2 is a control code. Edit control means for performing edit control such as insertion, deletion, or cursor movement on the character string code corresponding to the control code,
Reference numeral 5 is a display control means for reading the character string code edited by the edit control means 4 from the memory 3 for display, and 6a.
Is a display register for sequentially storing the character string code read by the display control means 5, and 7 is a display means for displaying the character string code stored in the display register 6a.

In such a configuration, the operation when a program including parentheses or the like or a sentence is input by the user will be described below.

First, the user inputs a character or the like by the input means 1, the character code corresponding to the character or the like is temporarily stored in the input register 2, and then the character code is stored in the memory 3 via the edit control means 4. Stored in. At this time, when the control code is input together with the character code, the editing control means 4 controls the character code according to the control code without sending the control code to the memory 3. For example, if it is an instruction to delete a character code already stored in the memory 3, it may be an instruction to delete the character code from the memory 3 and insert another character code between the character codes stored in the memory 3. For example, the character code is inserted in the corresponding position.

As a result, the display control means 5 causes the memory 3
The character string codes stored in are read out, these character string codes are sent to the display register 6a, and then displayed on the display means 7.

[0007]

However, when the character string code represents a parenthesis, and the parenthesis is displayed on the display means, when a plurality of front parentheses are input, the corresponding number of rear parentheses are input. There were many problems that the user could not immediately determine whether or not to do it.

[0010]

According to the present invention, by providing the means as described above, when the opening parenthesis is input by the input means, the lexical analysis means changes the count value of the parenthesis display color memory according to a predetermined rule. The opening parenthesis is displayed in the display color corresponding to the subsequent count value.

On the other hand, when the trailing parenthesis is input by the input means, the lexical analysis means changes the count value of the parenthesis display color memory according to the reverse order of the predetermined rule and displays the count value before the change. Display the above brackets in color.

At this time, when the front bracket and the rear bracket correspond as a pair, both brackets are displayed in the same color on the display means. Further, when the above-mentioned parentheses and the following parentheses do not correspond as a pair of pairs, they are displayed in a display color other than the display color displayed when both parentheses correspond as a pair of pairs.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to FIG. 1 and FIG.

FIG. 1 is a schematic block diagram of an information processing apparatus according to the present invention.

In FIG. 1, reference numeral 8 is a parenthesis display color memory for storing parenthesis display color codes corresponding to display colors at the time of displaying the first parenthesis and the second parenthesis.
As shown in, the correspondence between the display color of the brackets and the display color code of the brackets is stored and stored, and the number of inputs of each bracket is stored as a count value.

[0016]

[Table 1]

Reference numeral 9 increments the count value of the parenthesis display color memory 8 by +1 after judging that the character code corresponding to the opening parenthesis exists in the character codes sent from the display control means 5, and corresponds to the trailing parenthesis. A lexical analyzer 6b having a function of decrementing the count value of the parenthesis display color memory 8 by 1 after determining that there is a character code to be used, and determining the positive and negative signs of the count value sent from the parenthesis display color memory 8. Is a display register for storing the parenthesis display color code sent from the parenthesis display color memory 8 via the lexical analysis means 9 and the character code sent out from the display control means 5 via the lexical analysis means 9.

With this structure, the operation will be described with reference to the flowcharts shown in FIGS.

Characters other than parentheses are displayed in black, while the count value of the parenthesis display color memory 8 normally stores "0" as an initial value.

First, the user uses the input means 1 to input characters and the like. In step S1, the lexical analysis unit 9 determines whether or not the character code is a front bracket, and if it is a front bracket, the process proceeds to step S3, while if it is not the front bracket, the process proceeds to step S2. In step S2, the lexical analysis unit 9 determines whether or not the character code is a closing bracket, and if it is a closing bracket, the process proceeds to step S5, while if it is not a closing bracket, the process proceeds to step S9.

In step S3, the count value of the parenthesis display color memory 8 is incremented by 1. In step S4, the count value of the parenthesis display color memory 8 incremented by 1 in step S3 is set in the parenthesis display color register of the display register 6b via the lexical analysis means 9, and the process proceeds to step S9.

In step S5, the count value of the parenthesis display color memory 8 stored before that is set in the parenthesis display color register of the display register 6b via the lexical analysis means 9, and the process proceeds to step S6. In step S6,
The count value of the parenthesis display color memory 8 is decremented by 1.

In step S7, the lexical analysis means 9 determines the positive or negative sign of the parenthesis display color code sent from the parenthesis display color memory 8. If the sign is negative, the process proceeds to step S8, and if it is positive. If so, go to step S9.

In step S8, the value of the parenthesis display color code register is set to "0" which is the initial value, and then in step S9.
Proceed to. In step S9, the character code sent from the memory 3 via the display control means 5 and the lexical analysis means 9 is set in the character code register of the display register 6b, and the display color of the display means 7 at this time is bracketed. The display color corresponds to the bracket display color code stored in the display color code register.

Although the above is a general description of the operation, a detailed description will be given below with a specific example.

First, when a parenthesis is input using the input means 1, steps S1, S3, and S4 are performed.
Since the number of times the parentheses have been input is passed, the display colors of those parentheses are "purple", "blue", "light blue", ...

On the other hand, if a trailing bracket is entered using the input means 1, steps S1, S2, S5, and S6 are passed by the number of times the trailing bracket is entered. The display color of the rear brackets is "light blue", "blue", and "purple" sequentially from the front. As a result, the front brackets and the rear brackets have the same color group, and the user can grasp at a glance which front bracket and the rear bracket correspond to each other when the rear bracket is input.

By the way, when the number of times of inputting the rear bracket is larger than the number of times of inputting the front bracket, steps S1 and S are performed.
3 and the number of times step S4 is processed, step S
The number of times of processing 1, step S2, step S5, and step S6 increases. By this, step S7
Since it is determined that the count value of the parenthesis display color code register is negative, the parenthesis is displayed in step S8 with a color that is not used at all in the parenthesis, that is, "red" in the present application. The user can see that the rear parenthesis is displayed in “red”, and then understand that the rear parenthesis does not correspond to the front parenthesis. In such cases, the user needs to remove the trailing brackets.

On the other hand, if the number of opening parenthesis is more than the number of inputting the number of trailing parentheses, Steps S1, S3, and S4 are processed according to the number of times that Steps S1, S2, S5, and S6 are processed. The number of times to do increases. As a result, since the first parenthesis among the plurality of parenthesis does not display the same color of the second parenthesis, it can be understood that the first parenthesis does not correspond to the last parenthesis. In such cases, the user needs to add the trailing bracket.

In the above-mentioned embodiment, "(" and ")" are given as the opening and closing brackets, but the present invention is not limited to this, and other kinds of brackets can be supported. Is.

[0031]

As is apparent from the above description, in the present invention, when the front bracket and the rear bracket input by the input means correspond as a pair, they can be displayed in the same color. As a result of being able to grasp at a glance the correspondence between parentheses, it is possible to improve the input efficiency of characters and the like.

Further, when the opening brackets and the closing brackets do not correspond to each other as a pair, a display color other than the display color displayed as a pair can be displayed. As a result, it is possible to grasp at a glance when the parenthesis is input that there is no correspondence, so there is no need to correct the parenthesis after inputting all the characters.
