How to make newLISP quiet when it starts; start with ()
Hi all,
When I start newLISP from the shell, I'd like it to be quiet. No newLISP v.9.4.5 on BSD IPv4, execute 'newlisp -h' for more info message.
I would also like newLISP to start with () with the cursor in the middle.
Does newLISP use something similar to a .emacs?
What is the best way to make this modification.

There are support files for several editors here (including emacs support):
http://www.newlisp.org/index.cgi?Code_Contributions
There are also two functions to write more sophisticated REPL supoort in newLISP iself (newLISP 10.0 or later required):
http://www.newlisp.org/newlisp_manual.html#prompt-event
and here:
http://www.newlisp.org/newlisp_manual.h ... mand-event
The file newlisp-x.x.x/util/nls in the source distribution is a script showing how to use this functions and also includes command-line help. nls tries to combine the BASH shell with a newLISP REPL.
Cormullion from http://unbalanced-parentheses.nfshost.com has shown a few months back, how to build a repl using 'prompt-event' and 'command-event' which handles the entry of multi-line functions.
Last not least: on Mac OS X and other UNIX like OSs there is also support for .inputrc to customize for options from the linked in GNU readline library.

That has serious problems, so don't use it as is...Lutz wrote:Cormullion from http://unbalanced-parentheses.nfshost.com has shown a few months back, how to build a repl using 'prompt-event' and 'command-event' which handles the entry of multi-line functions.
Try putting this in ~/.init.lsp:
Code: Select all
(prompt-event (fn () ""))
Yes, Cormullion's repl code is more a proof of concept, than a finished program, but worth looking at for some interesting ideas.
And I forgot: there is built-in function name completion for newLISP native functions when hitting the TAB key. Hitting it twice shows all available functions. This is the same kind of support known from the Bash shell. OS X and other UNIXs only.

Wow.
Hi all,
Wow, a flood of responses right away. Thank you!
What I'm really trying to do is have (cursor) after a print.
(print "Input function please ") (cursor)
I would like a function to be called by input without the user having to worry about typing the (). They can just input the function name and press enter.

Well, you could put this into ~/.init.lsp:
to get this, for example:
but I think it's a really bad idea...! :)
Code: Select all
(prompt-event (fn () "Input function: "))
(command-event (fn (c)
(println "you typed " c " so I'm evaluating " (string "(" c ")") )
(string "(" c ")")))
Code: Select all
$ newlisp -c
context
you typed context so I'm evaluating (context)
MAIN
+ 2 2
you typed + 2 2 so I'm evaluating (+ 2 2)
4
reverse "aloha"
you typed reverse "aloha" so I'm evaluating (reverse "aloha")
"ahola"
exit
you typed exit so I'm evaluating (exit)
$

Hi cormullion,
I tried your suggestions and I couldn't get them to work. Perhaps I am not understanding. Here is some code that I hope is a little clearer.
Result of evaluated function main on screen:
What can I do for you? (cursor)

Code: Select all
(define (main)
(print "What can I assist you with? ")
code that will place (cursor) after the question
)

Cormullion was showing you how to change the newLISP command line behavior, but perhaps this explains what you really want to do:
http://www.newlisp.org/newlisp_manual.html#read-line
http://www.newlisp.org/newlisp_manual.html#read-line
Code: Select all
(define (main)
(print "What can I assist you with? ")
(set 'answer (read-line)))
)

in a nutshell I'd like the user to be able to run an already defined and loaded function from within the newLISP interpreter without the user needing to type the () every time.
The program I am working on can be downloaded by: svn checkout http://faridayix.googlecode.com/svn/trunk/ faridayix-read-only A Mac is recommend if you have time/desire.
I am sure I breaking rules and probably doing bad design. But it is fun :-)
