I'm using the following elisp snippet in a dedicated buffer to track progress of a
(with-current-buffer buf (setq proc (apply 'start-process "my-download" buf (list "wget" (if resume "-c" "") "-O" save-path url))) .... )
This is great in that it gives me
wget's progress, but the problem is that the buffer isn't interpreting a control character the way I want.
wget sends a
C-m after every progress update, about once a second, because it is expecting to be connected to a vt100 and wants the cursor to return to the beginning of the current line, this so the next progress message will over-write the former one. The emacs buffer just inserts a literal
C-m and accumulates lines.
When I run
wget directly from an emacs
ansi-term buffer, the progress messages appear fine, so I tried looking in the code, but couldn't figure out what specifically was being done for
C-m interpretation. I did consider using an
ansi-term buffer for my program, but it wouldn't be appropriate because I'll be inserting other information and text there that aren't terminal commands. What I would like is a
fundamental-mode buffer modified to react to
C-m by performing a
