Abstract

PURPOSE:To efficiently obtain a function by changing a text control means and adding a message annexing means and a message retrieving means without changing a text display means and a text editing means which are the main processing means of a text editor. CONSTITUTION:A text editor 10 is connected to a terminal 1, a source program file 2 and a compiler 11, and composed of a text display means 3, a text editing means 4, a text control means 5, a text memory area 6, a message retrieving means 7, a compiler starting means 8 and a message annexing means 9. When the user executes the editing designation to the screen of the terminal 1, information is executed from the text display means 3 to the text editing means 4, the text editing means 4 renews (step 25) the source program of the text memory area 6 through the text control means 5, and the text control means 5 renews the source program and simultaneously, deletes the accompanying error message.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a compile error display method in a text editor, and more particularly to a compile error display method in a text editor that is effective when correcting a program with a compile error.

[Conventional technology]

When correcting a source program compilation error from a terminal, write down the error message and then correct the source program using a text editor, or split the screen and operate each screen alternately to search for and respond to the error message. Modify the source program.

Conventionally, even text editors that automatically perform such operations have the same processing methods as those operated by humans, and have separate storage areas for error messages and source programs. At times, a screen was displayed that combined the source program and error message by searching for each and matching them.

In such conventional text editors, error messages output by the compiler and the source program to be edited are registered in separate storage areas.
The only way to correspond to those texts is by using line numbers.

Therefore, the process of renumbering the source program is
It is necessary to update not only the source program storage area but also the error message storage area, and both storage areas must be referenced simultaneously during display screen layout processing.

[Problem that the invention seeks to solve]

In the compile error display method in the conventional text editor described above, renumbering a source program requires not only updating the source program storage area but also updating the error message storage area, and it is also necessary to update the error message storage area in the display screen layout process. Since both storage areas must be referenced at the same time, not only does processing time become slower, but also two text management means and a dedicated text display means are required, making the structure of the text editor complex. .

In view of the above-mentioned points, an object of the present invention is to provide a compilation error display method in a text editor that allows immediate correction while viewing both the source program and the error message using a simple text editor structure. be.

[Means for solving problems]

The compile error display method in the text editor of the present invention consists of two types: a source program and an error message.
A text storage area that stores two texts at the same time, and a unified management of the text in this text storage area, which allows you to associate source programs with error messages and delete error messages that correspond to edited source lines. a text management means for inputting/outputting the text, a compiler starting means for starting a compiler and passing the source program in the text storage area to the compiler, and a message for outputting an error message output by the compiler to the text storage area. a merging means, a text display means for displaying the text in the text storage area on a screen of a terminal, and a message search means for searching the text storage area for an error message and notifying the text display means of the position of the text to be displayed. , text editing means for editing the source program in the text storage area according to the information of the text display means.

〔Example〕

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

Referring to FIG. 1, a text editor 10 employing an embodiment of the compile error display method of the present invention includes a terminal l, a source program file 2, and a compiler 11.
It is connected to a text display means 3, a text editing means 4, a text management means 5, a text storage area 6, a message retrieval means 7, a compiler starting means 8, and a message merging means 9.

Referring to FIG. 2, the process from startup to termination of the text editor 10 includes the source program reading step 2.
1, an error message detection step 22, a display screen determination step 23, a text display step 24, a text update step 25, and an end instruction detection step 26
, a source program writing step 27, a compile instruction detection step 28, and a compiler starting step 2
9 and an error message reading step 30.

FIGS. 3(a) and 3(bl) conceptually show before and after the screen changes when the compiler 11 is activated from the text editor IO and a compilation error is discovered.

Next, the operation of the compile error display method in the text editor of this embodiment configured as described above will be explained.

When a user issues an instruction to start the text editor 10 from the terminal 1, a source program is first read from the source program file 2 into the text storage area 6 (step 21). At this point, the text storage area 6 does not contain an error message, so no error message is detected (step 22), and the text display means 3 requests the text management means 5 for display text, as shown in FIG. (As shown in al, only the passed source program is displayed on the terminal 1 (step 24).

When the user specifies a vA collection on the screen of the terminal 1, the text display means 3 notifies the text editing means 4, and the text editing means 4 updates the source program in the text storage area 6 via the text management means 5. (Step 25)
. Up to this point, the operation is similar to that of a conventional text editor.

Instruct the compiler 11 to start from the terminal l (step 1
28), the compiler starting means 8 starts the compiler 11 (step 29) and passes the source program in the text storage area 6. When the compiler 11 discovers an error in the source program, the message merging means 9 reads the error message (step 30), formats it, and requests the text management means 5 to register it in the text storage area 6.

The text management means 5 retrieves the corresponding source program lines in the text storage area 6 and then merges the error messages. As a result, both the source program and the error message are stored in the text storage area 6 in the same order as the display image.

After this, it is determined again whether or not the text storage area 6 contains an error message (step 22), and since it is included at this point, control is transferred to the message retrieval means 7, and the error message passed from the text management means 5 is determined again. The message is searched and its position is notified to the text display means 3 (step 23).

The text display means 3 specifies a position to the text management means 5 and requests display text, but since the text consisting of the source program and error message is passed to the terminal 1, as shown in FIG. The error message and the source program before and after it are displayed simultaneously (step 24).

When the user specifies editing on the screen of the terminal 1, the text display means 3 sends a text) [The collection means 4 is notified and the text]
The I collection stage 4 updates the source program in the text storage area 6 via the text management means 5 (step 25), but the text management means 5 also deletes the accompanying error message at the same time as updating the source program.

A source program and an error message are stored in the text storage area 6 as text in the same format, but a flag for each text is added to each line to distinguish whether it is a source program or an error message. text storage area 6
The text management means 5, which manages the text in a unified manner, can pass any source program and/or error message to the means that requested the text by simply skipping unnecessary text using this flag.

The text editor 10 writes the source program in the text storage area 6 to the source program file 2 (step 2) based on the user's termination instruction (step 26).
7) Update and end the process.

〔Effect of the invention〕

As explained above, in the present invention, by simply issuing an instruction to start the compiler as a subcommand, when a compile error is found in the source program being edited, the error message is associated with the source program, and the error message is displayed on the terminal. The main processing method of existing text editors is a text editor that automatically positions the screen of There is an effect that the function can be efficiently realized by simply changing the text management means and adding message merging means and message retrieval means without changing certain text display means and text editing means.
