M-x term strange behaviour.

M-x term strange behaviour.

[Francis Moreau]

Hello,

I'm using "M-x term"  to get a shell inside emacs.

But it seems to not working as expected: for example when starting less(1),
inspecting a file (I know I could have used emacs for that) and exiting, the
terminal window is not restored as it was before starting less(1). Instead the
content of the file visited by less(1) still appears.

Of course this behaviour does not occur when using less(1) inside an xterm.

Can anybody give me some advices here ?

Should I use a different terminal (M-x terminal-emulator...) ?

Thanks

That may be an advandage, you can keep the text and copy it, yank it
...etc
When you don't need it anymore, just C-l.

It all depends on what you're doing.

In my case I loose the  context I'm working on and it bothers me.
But I agree that in sometimes it can be usefull.

IIIRC you can modify that behaviour via termcap/terminfo (I learned
too much about it when I was looking for a way to disable the blinking
cursor everywhere)

You can get the behaviour you want with less in the eshell, but as a
previous thread on this list discussed there are other areas where
the eshell differs from expected behaviour [1]

I still don't know when one would choose terminal-emulator, would someone
be able to provide an example when terminal-emulator would be required
for a task that term could not do?

Cheers,
Jonathan.

yes I would prefer use term + bash.

arg, I feared that's a terminfo stuff...

Running M-x term start a 'eterm-color' terminal where terminfo symbols
smcup and rmcup are not defined. Actually looking into the
eterm-color.ti file, these symbols are commented:

$ tail /usr/share/emacs/22.2/etc/e/eterm-color.ti
 	smso=\E[7m,
#	smcup=\E[?47h,
#	rmcup=\E[?47l,
#      rs2 may need to be added

So I tried to uncomment them and recompile the eterm-color.ti but
nothing change...

xterm terminal defines differently but doing the same doesn't improve anything.

Now I'm wondering if eterm-color terminal support these capabilities at all.

I'm clueless for now.
