  28 ;;; Commentary:
  29
  30 ;; This package provides the compile facilities documented in the Emacs user's
  31 ;; manual.
  32
  33 ;; This mode uses some complex data-structures:
  34
  35 ;;   LOC (or location) is a list of (COLUMN LINE FILE-STRUCTURE)
  36
  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.
  46
  47 ;;   FILE-STRUCTURE is a list of
  48 ;;   ((FILENAME . DIRECTORY) FORMATS (LINE LOC ...) ...)
  49
  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.
  59
  60 ;;   MESSAGE is a list of (LOC TYPE END-LOC)
  61
  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.

 279   "Alist that specifies how to match errors in compiler output.
 280 Note that on Unix everything is a valid filename, so these
 281 matchers must make some common sense assumptions, which catch
 282 normal cases.  A shorter list will be lighter on resource usage.
 283
 284 Instead of an alist element, you can use a symbol, which is
 285 looked up in `compilation-error-regexp-alist-alist'.  You can see
 286 the predefined symbols and their effects in the file
 287 `etc/compilation.txt' (linked below if you are customizing this).
 288
 289 Each elt has the form (REGEXP FILE [LINE COLUMN TYPE HYPERLINK
 290 HIGHLIGHT...]).  If REGEXP matches, the FILE'th subexpression
 291 gives the file name, and the LINE'th subexpression gives the line
 292 number.  The COLUMN'th subexpression gives the column number on
 293 that line.
 294
 295 If FILE, LINE or COLUMN are nil or that index didn't match, that
 296 information is not present on the matched line.  In that case the
 297 file name is assumed to be the same as the previous one in the
 298 buffer, line number defaults to 1 and column defaults to
 299 beginning of line's indentation.
 300
 301 FILE can also have the form (FILE FORMAT...), where the FORMATs
 302 \(e.g. \"%s.c\") will be applied in turn to the recognized file
 303 name, until a file of that name is found.  Or FILE can also be a
 304 function to return the filename.
 305
 306 LINE can also be of the form (LINE . END-LINE) meaning a range
 307 of lines.  COLUMN can also be of the form (COLUMN . END-COLUMN)
 308 meaning a range of columns starting on LINE and ending on
 309 END-LINE, if that matched.
 310
 311 TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
 312 TYPE can also be of the form (WARNING . INFO).  In that case this
 313 will be equivalent to 1 if the WARNING'th subexpression matched
 314 or else equivalent to 0 if the INFO'th subexpression matched.
 315 See `compilation-error-face', `compilation-warning-face',
 316 `compilation-info-face' and `compilation-skip-threshold'.
 317
 318 What matched the HYPERLINK'th subexpression has `mouse-face' and
 319 `compilation-message-face' applied.  If this is nil, the text
 320 matched by the whole REGEXP becomes the hyperlink.
