starting Emacs 21 in a terminal

starting Emacs 21 in a terminal

[Klaus Berndl]

I'm using NTEmacs 21.1 and cygwin-bash plus cygwin rxvt (a xterm-emulation).

If i call on the command-line "emacs -nw" to start Emacs with no-windows then
i always get the error: "emacs: standard input is not a tty" and Emacs doesn't
start.

What can be the problem...XEmacs starts fine with "xemacs -nw"...

Many Thanks,
Klaus

I suspect that the problem is some kind of incompatibility between
the Cygwin-compiled Bash/rxvt and NTEmacs: the way rxvt works is by
opening a pipe to the program(s) it runs, and it sounds like the pipe
it opens doesn't look as a tty to NTEmacs.

Is that a Cygwin-compiled XEmacs, per chance?

Anyway, this sort of thing should be reported to gnu.emacs.bug, not
here.

Yes, indeed.

Yes, you are right, but i was not sure if this is a bug and our explanation
tells me that this behavior can be a bug but can also be not a bug cause of
trying to run NTEmacs in a cygwin compiled terminal-program.

But next time i will report to gnu.emacs.bug....

Thanks,
Klaus

If NTEmacs can possibly be made compatible with the Cygwin terminal 
handling, IMHO it should.  So this is still worth reporting to 
bug-gnu-emacs (and maybe CC the Cygwin mailing list as well).

IIRC, there is a Cygwin environment option CYGWIN=tty, that might
help.

The basic problem is that there is no documented way in Windows to
create a pseudo-tty like in Unix.  So if you are not using the regular
NT console, Cygwin and rxvt have to play tricks, and even than it
doesn't always work.


Hope this helps, benny

No, i have this setting - it doesn't matter...

It doesn't work regardless if using the regular NT console or Cygwin rxvt...
I think Eli had the best explanation of the problem...i should write a bug
report...

Thanks,
Klaus

You mean, it doesn't work from Bash, right?  Because if you type
"emacs -nw" from the standard Windows shell (command.com or cmd.exe,
depending on the version of Windows you have), it does work.  At least
it did last time I tried.

Hello,
I found the pointer in emacs never stays at the original place when page-down 
is presse and followed by a page-up, for example, if you point to a place and 
do a page-down and followed by a page-up, the pointer is not at the original 
place before page-down is pressed but is at the top or bottom of the page, I 
used to use Mic's pager.el, but it doesn't work anymore  when .emacs has too 
many set ups ( I'm using JDEE ), and not sure what breaks it. Could anyone 
tell me any way to fix the pointer ?

Thanks
Mei

There is a variable scroll-preserve-screen-position.  And there is a
package scroll-in-place by Eric Eide.

GNU Emacs 21.2.1 works fine here in an NT console (W2K to be accurate)
started from the Cygwin shortcut.
