COLUMN and maybe ;; LINE will be nil for a message that doesn't contain them. Then the ;; location refers to a indented beginning of line or beginning of file. ;; Once any location in some file has been jumped to, the list is extended to ;; (COLUMN LINE FILE-STRUCTURE MARKER . VISITED) for all LOCs pertaining to ;; that file. ;; MARKER initially points to LINE and COLUMN in a buffer visiting that file. ;; Being a marker it sticks to some text, when the buffer grows or shrinks ;; before that point. VISITED is t if we have jumped there, else nil. ;; FILE-STRUCTURE is a list of ;; ((FILENAME . DIRECTORY) FORMATS (LINE LOC ...) ...) ;; FILENAME is a string parsed from an error message. DIRECTORY is a string ;; obtained by following directory change messages. DIRECTORY will be nil for ;; an absolute filename. FORMATS is a list of formats to apply to FILENAME if ;; a file of that name can't be found. ;; The rest of the list is an alist of elements with LINE as key. The keys ;; are either nil or line numbers. If present, nil comes first, followed by ;; the numbers in decreasing order. The LOCs for each line are again an alist ;; ordered the same way. Note that the whole file structure is referenced in ;; every LOC. ;; MESSAGE is a list of (LOC TYPE END-LOC) ;; TYPE is 0 for info or 1 for warning if the message matcher identified it as ;; such, 2 otherwise (for a real error). END-LOC is a LOC pointing to the ;; other end, if the parsed message contained a range. If the end of the ;; range didn't specify a COLUMN, it defaults to -1, meaning end of line. ;; These are the value of the `message' text-properties in the compilation ;; buffer. ;;; Code: (eval-when-compile (require 'cl)) (defgroup compilation nil "Run compiler as inferior of Emacs, parse error messages." :group 'tools :group 'processes) ;;;###autoload (defcustom compilation-mode-hook nil "*List of hook functions run by `compilation-mode' (see `run-hooks')." :type 'hook :group 'compilation) ;;;###autoload (defcustom compilation-window-height nil "*Number of lines in a compilation window.

You can see the predefined symbols and their effects in the file `etc/compilation.txt' (linked below if your are customizing this).

The COLUMN'th subexpression gives the column number on that line. If FILE, LINE or COLUMN are nil or that index didn't match, that information is not present on the matched line. In that case the file name is assumed to be the same as the previous one in the buffer, line number defaults to 1 and column defaults to beginning of line's indentation. FILE can also have the form (FILE FORMAT...), where the FORMATs \(e.g. \"%s.c\") will be applied in turn to the recognized file name, until a file of that name is found.

END-COLUMN) meaning a range of columns starting on LINE and ending on END-LINE, if that matched. TYPE is 2 or nil for a real error or 1 for warning or 0 for info.
