Thanks for the bug report. I'll take a look at it. I tried the following: 

Welcome to testfts2 running at /home/nsadmin/bin/nsd (pid 916)

testfts2:nscp 7> $h {put Object Object} save $s
testfts2:nscp 8> [$h {get Object} save] toString
hello world

So it appears that even though an error message is received, the import is still working correctly. I'll go ahead and fix that.

I fixed this bug and checked the changes into cvs.  The fix should come out in the next release 1.0.4.  I'm currently adding an extensive test harness to catch these kinds of bugs, and I'll do the release once I'm finished - probably in another week.

By the way, does anybody have readline support working for nscp?

Posted by Dan Wickstrom on 08/08/02 10:43 PM
It occured to me that you can use shell mode in emacs, and use the builtin history recall mechanism to get a limited readline support for nscp. I map the history recall to the up/down arrows using the following emacs incantation: 

(add-hook 'shell-mode-hook 
	  (function 
	   (lambda ()
	     (define-key comint-mode-map 'up 'comint-previous-input)
	     (define-key comint-mode-map 'down 'comint-next-input))))

It also works for sql mode when you're forced to use oracle and work with sqlplus 

(add-hook 'sql-interactive-mode-hook
	  (function 
	   (lambda ()
	     (define-key comint-mode-map 'up 'comint-previous-input)
	     (define-key comint-mode-map 'down 'comint-next-input))))

I don't care what people say, emacs rules.
