I use emacs23.4 on window xp. So the shell-mode use windows cmd.exe.

I encountered such a problem that If I use the commands which ask for user input（.e.g email, password）, my emacs does not display the request.

I have commented out all configuration in .emacs.

The picture shows the result that I input "heroku login" in emacs and cmd.

  • Know that you can start emacs with the `-q` option to load neither ~/.emacs nor default.el. This might be easier than commenting out your configuration. – N.N. Apr 04 '12 at 09:03
  • may be trying `ansi-term` instead of shell. (press `C-m` for `RET` in ansi-term) – kindahero Apr 04 '12 at 09:26
  • Thanks. N.N. and kindahero. I try to M-x ansi-term. But I got an error "Spawning child process: invalid argument". – coordinate Apr 04 '12 at 11:07

This is a known issue with emacs on Windows: https://www.gnu.org/software/emacs/windows/Sub_002dprocesses.html#index-subprocesses_002c-hanging-when-reading-input-213

Unfortunately, there's no easy work around. You're best alternative is probably to provide your heroku credentials in a .netrc file to avoid being prompted.

setvbuf (stdout, NULL, _IONBF, 0);

seems that there is a workabl but not satisfied answer here :

printf not printing on console
