513 ;; We want to catch the Guile file-headers but not the Emacs
514 ;; byte-compilation headers, because that will cause next-error
515 ;; and prev-error to break, because the files "toplevel form" and
516 ;; "end of data" does not exist.
517 ;;
518 ;; To differentiate between these two cases, we require that the
519 ;; file-match must always contain an extension.
520 ;;
521 ;; We should also only treat this as "info", not "error", because
522 ;; we do not know what lines will follow.
525 )
530 "Alist that specifies how to match errors in compiler output.
531 On GNU and Unix, any string is a valid filename, so these
532 matchers must make some common sense assumptions, which catch
533 normal cases. A shorter list will be lighter on resource usage.
535 Instead of an alist element, you can use a symbol, which is
536 looked up in `compilation-error-regexp-alist-alist'. You can see
537 the predefined symbols and their effects in the file
538 `etc/compilation.txt' (linked below if you are customizing this).
540 Each elt has the form (REGEXP FILE [LINE COLUMN TYPE HYPERLINK
541 HIGHLIGHT...]). If REGEXP matches, the FILE'th subexpression
542 gives the file name, and the LINE'th subexpression gives the line
543 number. The COLUMN'th subexpression gives the column number on
544 that line.
546 If FILE, LINE or COLUMN are nil or that index didn't match, that
547 information is not present on the matched line. In that case the
548 file name is assumed to be the same as the previous one in the
549 buffer, line number defaults to 1 and column defaults to
550 beginning of line's indentation.
552 FILE can also have the form (FILE FORMAT...), where the FORMATs
554 name, until a file of that name is found. Or FILE can also be a
555 function that returns (FILENAME) or (RELATIVE-FILENAME . DIRNAME).
556 In the former case, FILENAME may be relative or absolute, or it may
557 be a buffer.
559 LINE can also be of the form (LINE . END-LINE) meaning a range
560 of lines. COLUMN can also be of the form (COLUMN . END-COLUMN)
561 meaning a range of columns starting on LINE and ending on
562 END-LINE, if that matched.
564 TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
565 TYPE can also be of the form (WARNING . INFO). In that case this
566 will be equivalent to 1 if the WARNING'th subexpression matched
567 or else equivalent to 0 if the INFO'th subexpression matched.
568 See `compilation-error-face', `compilation-warning-face',
569 `compilation-info-face' and `compilation-skip-threshold'.
571 What matched the HYPERLINK'th subexpression has `mouse-face' and
572 `compilation-message-face' applied. If this is nil, the text
573 matched by the whole REGEXP becomes the hyperlink.
575 Additional HIGHLIGHTs take the shape (SUBMATCH FACE), where
576 SUBMATCH is the number of a submatch and FACE is an expression
577 which evaluates to a face name (a symbol or string).
578 Alternatively, FACE can evaluate to a property list of the
579 form (face FACE PROP1 VAL1 PROP2 VAL2 ...), in which case all the
580 listed text properties PROP# are given values VAL# as well."

596 of variants, e.g. different languages. The remaining elements are all of the
597 form (DIR . LEAVE). If for any one of these the DIR'th subexpression
598 matches, that is a directory name. If LEAVE is nil or the corresponding
599 LEAVE'th subexpression doesn't match, this message is about going into another
