29 ;; This package provides the compile facilities documented in the Emacs user's
32 ;; This mode uses some complex data-structures:
34 ;; LOC (or location) is a list of (COLUMN LINE FILE-STRUCTURE)
36 ;; COLUMN and LINE are numbers parsed from an error message. COLUMN and maybe
37 ;; LINE will be nil for a message that doesn't contain them. Then the
38 ;; location refers to a indented beginning of line or beginning of file.
39 ;; Once any location in some file has been jumped to, the list is extended to
40 ;; (COLUMN LINE FILE-STRUCTURE MARKER TIMESTAMP . VISITED)
41 ;; for all LOCs pertaining to that file.
42 ;; MARKER initially points to LINE and COLUMN in a buffer visiting that file.
43 ;; Being a marker it sticks to some text, when the buffer grows or shrinks
44 ;; before that point. VISITED is t if we have jumped there, else nil.
45 ;; TIMESTAMP is necessary because of "incremental compilation": `omake -P'
46 ;; polls filesystem for changes and recompiles when a file is modified
47 ;; using the same *compilation* buffer. this necessitates re-parsing markers.
49 ;; FILE-STRUCTURE is a list of
50 ;; ((FILENAME . DIRECTORY) FORMATS (LINE LOC ...) ...)
52 ;; FILENAME is a string parsed from an error message. DIRECTORY is a string
53 ;; obtained by following directory change messages. DIRECTORY will be nil for
54 ;; an absolute filename. FORMATS is a list of formats to apply to FILENAME if
55 ;; a file of that name can't be found.
56 ;; The rest of the list is an alist of elements with LINE as key. The keys
57 ;; are either nil or line numbers. If present, nil comes first, followed by
58 ;; the numbers in decreasing order. The LOCs for each line are again an alist
59 ;; ordered the same way. Note that the whole file structure is referenced in
62 ;; MESSAGE is a list of (LOC TYPE END-LOC)
64 ;; TYPE is 0 for info or 1 for warning if the message matcher identified it as
65 ;; such, 2 otherwise (for a real error). END-LOC is a LOC pointing to the
66 ;; other end, if the parsed message contained a range. If the end of the
67 ;; range didn't specify a COLUMN, it defaults to -1, meaning end of line.
68 ;; These are the value of the `message' text-properties in the compilation

447 On GNU and Unix, any string is a valid filename, so these
448 matchers must make some common sense assumptions, which catch
449 normal cases. A shorter list will be lighter on resource usage.
451 Instead of an alist element, you can use a symbol, which is
452 looked up in `compilation-error-regexp-alist-alist'. You can see
453 the predefined symbols and their effects in the file
454 `etc/compilation.txt' (linked below if you are customizing this).
456 Each elt has the form (REGEXP FILE [LINE COLUMN TYPE HYPERLINK
457 HIGHLIGHT...]). If REGEXP matches, the FILE'th subexpression
458 gives the file name, and the LINE'th subexpression gives the line
459 number. The COLUMN'th subexpression gives the column number on
462 If FILE, LINE or COLUMN are nil or that index didn't match, that
463 information is not present on the matched line. In that case the
464 file name is assumed to be the same as the previous one in the
465 buffer, line number defaults to 1 and column defaults to
466 beginning of line's indentation.
468 FILE can also have the form (FILE FORMAT...), where the FORMATs
469 \(e.g. \"%s.c\") will be applied in turn to the recognized file
470 name, until a file of that name is found. Or FILE can also be a
471 function that returns (FILENAME) or (RELATIVE-FILENAME . DIRNAME).
472 In the former case, FILENAME may be relative or absolute.
474 LINE can also be of the form (LINE . END-LINE) meaning a range
475 of lines. COLUMN can also be of the form (COLUMN . END-COLUMN)
476 meaning a range of columns starting on LINE and ending on
477 END-LINE, if that matched.
479 TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
480 TYPE can also be of the form (WARNING . INFO). In that case this
481 will be equivalent to 1 if the WARNING'th subexpression matched
482 or else equivalent to 0 if the INFO'th subexpression matched.
483 See `compilation-error-face', `compilation-warning-face',
484 `compilation-info-face' and `compilation-skip-threshold'.
486 What matched the HYPERLINK'th subexpression has `mouse-face' and
487 `compilation-message-face' applied. If this is nil, the text
