487 "Alist that specifies how to match errors in compiler output.
488 On GNU and Unix, any string is a valid filename, so these
489 matchers must make some common sense assumptions, which catch
490 normal cases. A shorter list will be lighter on resource usage.
492 Instead of an alist element, you can use a symbol, which is
493 looked up in `compilation-error-regexp-alist-alist'. You can see
494 the predefined symbols and their effects in the file
495 `etc/compilation.txt' (linked below if you are customizing this).
497 Each elt has the form (REGEXP FILE [LINE COLUMN TYPE HYPERLINK
498 HIGHLIGHT...]). If REGEXP matches, the FILE'th subexpression
499 gives the file name, and the LINE'th subexpression gives the line
500 number. The COLUMN'th subexpression gives the column number on
501 that line.
503 If FILE, LINE or COLUMN are nil or that index didn't match, that
504 information is not present on the matched line. In that case the
505 file name is assumed to be the same as the previous one in the
506 buffer, line number defaults to 1 and column defaults to
507 beginning of line's indentation.
509 FILE can also have the form (FILE FORMAT...), where the FORMATs
511 name, until a file of that name is found. Or FILE can also be a
512 function that returns (FILENAME) or (RELATIVE-FILENAME . DIRNAME).
513 In the former case, FILENAME may be relative or absolute.
515 LINE can also be of the form (LINE . END-LINE) meaning a range
516 of lines. COLUMN can also be of the form (COLUMN . END-COLUMN)
517 meaning a range of columns starting on LINE and ending on
518 END-LINE, if that matched.
520 TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
521 TYPE can also be of the form (WARNING . INFO). In that case this
522 will be equivalent to 1 if the WARNING'th subexpression matched
523 or else equivalent to 0 if the INFO'th subexpression matched.
524 See `compilation-error-face', `compilation-warning-face',
525 `compilation-info-face' and `compilation-skip-threshold'.
527 What matched the HYPERLINK'th subexpression has `mouse-face' and
528 `compilation-message-face' applied. If this is nil, the text
529 matched by the whole REGEXP becomes the hyperlink.
531 Additional HIGHLIGHTs take the shape (SUBMATCH FACE), where
532 SUBMATCH is the number of a submatch and FACE is an expression
533 which evaluates to a face name (a symbol or string).
534 Alternatively, FACE can evaluate to a property list of the
535 form (face FACE PROP1 VAL1 PROP2 VAL2 ...), in which case all the
536 listed text properties PROP# are given values VAL# as well."

552 of variants, e.g. different languages. The remaining elements are all of the
553 form (DIR . LEAVE). If for any one of these the DIR'th subexpression
554 matches, that is a directory name. If LEAVE is nil or the corresponding
555 LEAVE'th subexpression doesn't match, this message is about going into another
556 directory. If it does match anything, this message is about going back to the

596 especially the TAB character.
