} It looks like I should be adding two things to the FAQ. This is the

} 3.6: Why does zsh not work in an Emacs shell mode any more?
}
} Placing a
}
} (setenv "TERM" "emacs")
}
} in your ~/.emacs file seems to fix this.
This may not be universal, based on the discussion on zsh-users. It
appears to work for the default shell-mode (shell.el) but not for the
enhanced shell-mode supplied by comint (comint.el).
Looking at the lisp code in comint.el, it appears emacs forces TERM=dumb
for systems where emacs is compiled with terminfo, and TERM=emacs for
those where it's compiled with termcap. There's no hook to override
this; you can only redefine comint-exec-1 as in the sample I sent, which
is bad if comint gets upgraded.
This:
} that are run from within emacs, you can instead use
}
} (setenv "ESHELL" "~/bin/eshell")
}
} and then put `TERM=emacs exec zsh' in the file ~/bin/eshell.
ought to work in either case, though for the FAQ I'd restate it as
and then put
#!/bin/sh
TERM=emacs exec zsh
in the file ~/bin/eshell, and `chmod +x ~/bin/eshell'.
Finally I'd add (via Alain Caron <alainc@xxxxxxxxx>):
If none of the above works, place
[[ -n "$EMACS" ]] && unsetopt zle
in your $ZDOTDIR/.zshrc file.
If you want to say something about terminal mode:
[[ -n "$EMACS" ]] && {
[[ "$TERM" = eterm ]] && TERM=vt100 || unsetopt zle
}
} 3.16: How does the alternative loop syntax, e.g. `while {...} {...}' work?
I agree with Zoltan's remarks about this; particularly about stronger
admonition to avoid the short forms in scripts.
