30 ;; This package provides the compile facilities documented in the Emacs user's
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
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
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

289 Note that on Unix everything is a valid filename, so these
290 matchers must make some common sense assumptions, which catch
291 normal cases. A shorter list will be lighter on resource usage.
293 Instead of an alist element, you can use a symbol, which is
294 looked up in `compilation-error-regexp-alist-alist'. You can see
295 the predefined symbols and their effects in the file
296 `etc/compilation.txt' (linked below if you are customizing this).
298 Each elt has the form (REGEXP FILE [LINE COLUMN TYPE HYPERLINK
299 HIGHLIGHT...]). If REGEXP matches, the FILE'th subexpression
300 gives the file name, and the LINE'th subexpression gives the line
301 number. The COLUMN'th subexpression gives the column number on
304 If FILE, LINE or COLUMN are nil or that index didn't match, that
305 information is not present on the matched line. In that case the
306 file name is assumed to be the same as the previous one in the
307 buffer, line number defaults to 1 and column defaults to
308 beginning of line's indentation.
310 FILE can also have the form (FILE FORMAT...), where the FORMATs
311 \(e.g. \"%s.c\") will be applied in turn to the recognized file
312 name, until a file of that name is found. Or FILE can also be a
313 function to return the filename.
315 LINE can also be of the form (LINE . END-LINE) meaning a range
316 of lines. COLUMN can also be of the form (COLUMN . END-COLUMN)
317 meaning a range of columns starting on LINE and ending on
318 END-LINE, if that matched.
320 TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
321 TYPE can also be of the form (WARNING . INFO). In that case this
322 will be equivalent to 1 if the WARNING'th subexpression matched
323 or else equivalent to 0 if the INFO'th subexpression matched.
324 See `compilation-error-face', `compilation-warning-face',
325 `compilation-info-face' and `compilation-skip-threshold'.
327 What matched the HYPERLINK'th subexpression has `mouse-face' and
328 `compilation-message-face' applied. If this is nil, the text
329 matched by the whole REGEXP becomes the hyperlink.
