The usual way to do that is to keep the "unprocessed output" in a process property (see `process-put` and `process-get`) or in a global var, e.g.: (lambda (proc output) (setq output (concat (process-get proc 'foo--leftover) output)) (let ((end (string-match ".*\\'" output))) (process-put proc 'foo--leftover (substring output end)) (setq output (substring output 0 end))) ;; Now `output` contains only wholelines. ...) - Stefan
