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

309 "Alist that specifies how to match errors in compiler output.
310 On GNU and Unix, any string is a valid filename, so these
311 matchers must make some common sense assumptions, which catch
312 normal cases. A shorter list will be lighter on resource usage.
314 Instead of an alist element, you can use a symbol, which is
315 looked up in `compilation-error-regexp-alist-alist'. You can see
316 the predefined symbols and their effects in the file
317 `etc/compilation.txt' (linked below if you are customizing this).
319 Each elt has the form (REGEXP FILE [LINE COLUMN TYPE HYPERLINK
320 HIGHLIGHT...]). If REGEXP matches, the FILE'th subexpression
321 gives the file name, and the LINE'th subexpression gives the line
322 number. The COLUMN'th subexpression gives the column number on
323 that line.
325 If FILE, LINE or COLUMN are nil or that index didn't match, that
326 information is not present on the matched line. In that case the
327 file name is assumed to be the same as the previous one in the
328 buffer, line number defaults to 1 and column defaults to
329 beginning of line's indentation.
331 FILE can also have the form (FILE FORMAT...), where the FORMATs
333 name, until a file of that name is found. Or FILE can also be a
334 function to return the filename.
336 LINE can also be of the form (LINE . END-LINE) meaning a range
337 of lines. COLUMN can also be of the form (COLUMN . END-COLUMN)
338 meaning a range of columns starting on LINE and ending on
339 END-LINE, if that matched.
341 TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
342 TYPE can also be of the form (WARNING . INFO). In that case this
343 will be equivalent to 1 if the WARNING'th subexpression matched
344 or else equivalent to 0 if the INFO'th subexpression matched.
345 See `compilation-error-face', `compilation-warning-face',
346 `compilation-info-face' and `compilation-skip-threshold'.
348 What matched the HYPERLINK'th subexpression has `mouse-face' and
349 `compilation-message-face' applied. If this is nil, the text
350 matched by the whole REGEXP becomes the hyperlink.
352 Additional HIGHLIGHTs as described under `font-lock-keywords' can
353 be added."

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