Re: piping files to vim command line, results in dead screen

[Joe Zbiciak]

Zenaan, All,

I found it, and it's not really a screen issue, but more
likely a shell and/or VIM related issue.  VIM does this
magic:

/*
 * If reading stdin results in an error, continue 
 * reading stderr.
 * This helps when using "foo | xargs vim".
 */
if (!did_read_something  &&
    !isatty(read_cmd_fd) && 
    read_cmd_fd == 0)
{
    int m = cur_tmode;

    /* We probably set the wrong file descriptor 
     * to raw mode.  Switch back to cooked mode, 
     * use another descriptor and set the mode to
     * what it was. */
    settmode(TMODE_COOK);
#ifdef HAVE_DUP
    /* Use stderr for stdin, also works for 
     * shell commands. */
    close(0);
    dup(2);
#else
    /* read from stderr instead of stdin */
    read_cmd_fd = 2;    
#endif
    settmode(m);
}

Cute, huh?  Well, it appears the *shell* (bash) gets
confused when VIM exits, at least on my RedHat 7.3 box.
In my case, it appears bash's readline just hangs.  I'll
grasp at straws and suggest it might be
controlling-terminal
related.

The AIX and Solaris boxen also get a little weird, but
they're fixed with an "stty sane."

Mystery "solved?"


Regards,

--Joe
