455 "Alist that specifies how to match errors in compiler output.
456 On GNU and Unix, any string is a valid filename, so these
457 matchers must make some common sense assumptions, which catch
458 normal cases. A shorter list will be lighter on resource usage.
460 Instead of an alist element, you can use a symbol, which is
461 looked up in `compilation-error-regexp-alist-alist'. You can see
462 the predefined symbols and their effects in the file
463 `etc/compilation.txt' (linked below if you are customizing this).
465 Each elt has the form (REGEXP FILE [LINE COLUMN TYPE HYPERLINK
466 HIGHLIGHT...]). If REGEXP matches, the FILE'th subexpression
467 gives the file name, and the LINE'th subexpression gives the line
468 number. The COLUMN'th subexpression gives the column number on
469 that line.
471 If FILE, LINE or COLUMN are nil or that index didn't match, that
472 information is not present on the matched line. In that case the
473 file name is assumed to be the same as the previous one in the
474 buffer, line number defaults to 1 and column defaults to
475 beginning of line's indentation.
477 FILE can also have the form (FILE FORMAT...), where the FORMATs
479 name, until a file of that name is found. Or FILE can also be a
480 function that returns (FILENAME) or (RELATIVE-FILENAME . DIRNAME).
481 In the former case, FILENAME may be relative or absolute.
483 LINE can also be of the form (LINE . END-LINE) meaning a range
484 of lines. COLUMN can also be of the form (COLUMN . END-COLUMN)
485 meaning a range of columns starting on LINE and ending on
486 END-LINE, if that matched.
488 TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
489 TYPE can also be of the form (WARNING . INFO). In that case this
490 will be equivalent to 1 if the WARNING'th subexpression matched
491 or else equivalent to 0 if the INFO'th subexpression matched.
492 See `compilation-error-face', `compilation-warning-face',
493 `compilation-info-face' and `compilation-skip-threshold'.
495 What matched the HYPERLINK'th subexpression has `mouse-face' and
496 `compilation-message-face' applied. If this is nil, the text
497 matched by the whole REGEXP becomes the hyperlink.
499 Additional HIGHLIGHTs take the shape (SUBMATCH FACE), where
500 SUBMATCH is the number of a submatch and FACE is an expression
501 which evaluates to a face name (a symbol or string).
502 Alternatively, FACE can evaluate to a property list of the
503 form (face FACE PROP1 VAL1 PROP2 VAL2 ...), in which case all the
504 listed text properties PROP# are given values VAL# as well."

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

564 especially the TAB character.
