(compilation-error-regexp-alist): Doc fix: optional cdrs give
string containing %s to produce the file name from the matched text.
(compilation-find-file): Reorder args: MARKER first, then FILENAME, DIR,
and new arg &rest FORMATS (as they appear in parsed the fileinfo lists).
Try each of the FORMATS in each directory tried.
(compilation-next-error-locus): Apply compilation-find-file to the FILEINFO
list.
(compilation-parse-errors): Instead of a cons (DIR . FILE), make a list
(FILE DIR [FORMATS...]) using the 4th cdr of the matching elt of
regexp-alist.
compilation-mode major mode, rather than internal state variables. Don't
want to match a buffer that was once in compilation-minor-mode but is not now.
(compilation-error-regexp-alist): Make first regexp match column numbers too.
Remove regexp for "prog:file:line: error".
Replace GNAT 1.82 regexp with "prog: file:line\(:col\)?: error".
(compilation-parse-errors): If spec has a column subexpr, but it was
optional and didn't match, ignore it.
broken out from compile-internal.
Don't change window height if it is the frame root window.
(compile-internal): Call it.
(compilation-goto-locus): Call it.
Use any visible frame already showing the compilation buffer.
Test only its nilness.
(compile-goto-error): Pass (consp ARGP) to compile-reinitialize-errors
instead of ARGP itself.
(next-error): Code broken out into two new functions; call them.
(compilation-next-error-locus): New function; bulk of code from next-error.
Silently skip errors whose source loci are markers in killed buffers.
(compilation-goto-locus): New function, final code from next-error.
Element lists can now contain a 4th elt giving subexpr for the column.
(next-error): Handle error records with column numbers.
(compilation-parse-errors): Parse column numbers when the alist elt
specifies it. Use string-to-int instead of read for numbers from buffer
text.
absolute file names culled from error msgs.
(compile-abbreviate-directory): Prepend comint-file-name-prefix (if boundp)
to DIR before other processing.
(compilation-forget-errors): Reset compilation-parsing-end to 1 here.
(compile-reinitialize-errors): Don't reset compilation-parsing-end after
calling compilation-forget-errors.
Comment out gratuitous switch-to-buffer call; what was the rationale for it?
Don't check compilation-parsing-end (removed local AT-START); instead
always append to compilation-old-error-list, it will be nil if at start.
If compilation-error-list is non-nil before calling the parser, restore its
previous value afterwards; it still indicates the current error position.
Subtract the length of the existing compilation-error-list from
FIND-AT-LEAST when calling the parser.
(compilation-parse-errors): Don't check LIMIT-SEARCH at end of loop.
Inside check it inside each case of the cond; in error case we must discard
the last new error before stopping (just as for FIND-AT-LEAST).
Use floating-point in buffer percentage calculation, to avoid integer
overflow.
