BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compiler grammar diagnosis message list output method, and more particularly to an error message output method for compiler translation list output.

0002

[Background Art] The compiler's translation list output method is as follows:
A grammar diagnosis message is inserted at the error location on the source, the line number with the error is output at the end of the translation list, the error number for each line is output next to it, and the error message text is displayed on the next page. There is a method that outputs them all at once.

0003

[Problem to be Solved by the Invention] In the conventional grammar diagnosis message output method, in which a grammar diagnosis message is inserted at an error location on the source, if the same error occurs in multiple lines, the message body is This is not economical as it will result in output.

[0004] In addition, with the method of outputting the error line number and error message text together at the end of the translation list, when correcting an error, visually check the line number where the error is detected from the number of the error message you want to correct. In particular, if there are many errors, it is necessary to search across pages for the line number of the error, which is inefficient.

[0005]

[Means for Solving the Problems] The grammar diagnosis message list output method of the compiler of the present invention provides an error message when an error is detected in the grammar diagnosis in the output of the grammar diagnosis message for the compiler's translation list output. An error message number/error line number registration means that saves the number and error line number, and after all diagnostics are completed, the error message body corresponding to the error message number saved during grammar diagnosis is searched from the message storage file, and the error message body is stored. and a list output means for storing the error line numbers on an output buffer and outputting them on a list so as to output them successively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention. This embodiment consists of a source program 1 input to the compiler, a control section 2, an error message storage file 3, an error message number/error line number storage area 4, and a translation list 5 output from the compiler. Ru.

The error message number/error line number registration means 22 performs a grammar diagnosis 21 on the input source program 1, and when an error is detected, the error message number is stored in the error message number/error line number storage area 4. , followed by the error line number.

The list output means 23 searches the error message numbers stored in the error message number/error line number storage area 4 after all the diagnoses are completed, and if there is the same error number, the list output means 23 searches for the error message numbers stored in the error message number/error line number storage area 4, and if there is an identical error number, the list output means 23 searches for the error message numbers stored in the error message number/error line number storage area 4. Edit the error line numbers so that they are all in one line. and,
The error message body corresponding to the error number is searched from the error message storage file 3 and set in the output buffer together with the error message number and error line number.

FIG. 2 shows an example of an error message output from a compiler translation list.

[0011]

[Effects of the Invention] As explained above, the present invention improves error correction efficiency and outputs the error message text and error line numbers side by side in response to the error message output of the compiler translation list. This has the effect of reducing the list size.

Claims (1)

[Claims] Claim 1: Error message number/error line number registration means for storing an error message number and error line number when an error is detected in grammar diagnosis in the output of a grammar diagnosis message with respect to the translation list output of a compiler. After all the diagnostics are completed, search the message storage file for the error message text corresponding to the error message number saved during grammar diagnosis, and write the error message text and error line number onto the output buffer so that they are output successively. 1. A grammar diagnostic message list output method for a compiler, comprising a list output means for storing and outputting the message on a list.
