517 On GNU and Unix, any string is a valid filename, so these
518 matchers must make some common sense assumptions, which catch
519 normal cases. A shorter list will be lighter on resource usage.
521 Instead of an alist element, you can use a symbol, which is
522 looked up in `compilation-error-regexp-alist-alist'. You can see
523 the predefined symbols and their effects in the file
524 `etc/compilation.txt' (linked below if you are customizing this).
526 Each elt has the form (REGEXP FILE [LINE COLUMN TYPE HYPERLINK
527 HIGHLIGHT...]). If REGEXP matches, the FILE'th subexpression
528 gives the file name, and the LINE'th subexpression gives the line
529 number. The COLUMN'th subexpression gives the column number on
532 If FILE, LINE or COLUMN are nil or that index didn't match, that
533 information is not present on the matched line. In that case the
534 file name is assumed to be the same as the previous one in the
535 buffer, line number defaults to 1 and column defaults to
536 beginning of line's indentation.
538 FILE can also have the form (FILE FORMAT...), where the FORMATs
539 \(e.g. \"%s.c\") will be applied in turn to the recognized file
540 name, until a file of that name is found. Or FILE can also be a
541 function that returns (FILENAME) or (RELATIVE-FILENAME . DIRNAME).
542 In the former case, FILENAME may be relative or absolute.
544 LINE can also be of the form (LINE . END-LINE) meaning a range
545 of lines. COLUMN can also be of the form (COLUMN . END-COLUMN)
546 meaning a range of columns starting on LINE and ending on
547 END-LINE, if that matched.
549 TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
550 TYPE can also be of the form (WARNING . INFO). In that case this
551 will be equivalent to 1 if the WARNING'th subexpression matched
552 or else equivalent to 0 if the INFO'th subexpression matched.
553 See `compilation-error-face', `compilation-warning-face',
554 `compilation-info-face' and `compilation-skip-threshold'.
556 What matched the HYPERLINK'th subexpression has `mouse-face' and
557 `compilation-message-face' applied. If this is nil, the text
558 matched by the whole REGEXP becomes the hyperlink.
560 Additional HIGHLIGHTs take the shape (SUBMATCH FACE), where
561 SUBMATCH is the number of a submatch and FACE is an expression
562 which evaluates to a face name (a symbol or string).
563 Alternatively, FACE can evaluate to a property list of the
564 form (face FACE PROP1 VAL1 PROP2 VAL2 ...), in which case all the
565 listed text properties PROP# are given values VAL# as well."
