LTK: listbox
LTK users here? :) I've come across certain issues concerning the listbox widget. First of all, evidently there's no `activate' method. Suppose I create a listbox with three items and select the second (i. e. the middle) one at the initialization: (with-ltk () (let ((l (make-instance 'listbox))) (li...

Re: sed like utility for s-expr
Why not just READ s-expressions in a loop and process them? A simple example: (defun foo (in out process-sexpr) "Read s-expressions from the stream IN, process them one by one using the function PROCESS-SEXPR and print the results to the steram OUT." (do ((sexpr (read in nil :eof) (read in...

Re: Using libraries in CLISP scripts
Thanks, Goheeca, that's great! Both the news and the function, I mean. :) BTW apparently the most speedy approach is to put ltk.fas(l) in the script's directory and load it, then SBCL runs as fast as Python and CLISP is just a little bit slower. However, this is very ad hoc . Perhaps the right thing...

Re: Using libraries in CLISP scripts
So far SBCL wins, both in performance and in outlook. It's a pity it doesn't support shebang. (require 'asdf) (push (merge-pathnames "asdf/" (user-homedir-pathname)) asdf:*central-registry*) (require 'ltk) $ time echo hello world | sbcl --script show-message-sbcl.lisp real 0m1.202s user 0m...

Using libraries in CLISP scripts
Hi all. I'm trying to create a simple CLISP script and I'd like to find out what are the most efficient and common ways of loading a library. The script should take a line from stdin and display a message box containing this line. I'm using LTK. This is the Python prototype: #!/usr/bin/env python3 #...

File descriptors
I'm trying to make a Common Lisp front end to the Asymptote vector graphics language . I'd like to establish communication between a Lisp process and an Asymptote process and I have problems with this. Somehow Asymptote is hard to communicate with. The only working piece of code I have (stripped fro...
