• [bugfix]
  • fixed error signalled from TK interpreter when passing floating point value from lisp.

• [new feature]
  • added procedures related to events management
• [bugfix]
  • fixed escaping of strings inserted in a text widget.

• [new feature]

  • added command option for configuring button widget, for example:

    (with-nodgui ()
      (let ((button (make-instance 'button :text "foo")))
        (configure  button
                    :command
                    (lambda ()
                      (format t "quitting~%")
                      (exit-nodgui))
                    :text "Quit"
                    :underline 0)
        (pack button)))
    

  • moved from bordeaux threads version 1 API to version 2.
• [bugfix]
  • fixed inconsistency in widget initialization intargs, accepted :orient instead of :orientation, the latter is not accepted by configure (thanks Arkdae!);
  • added missing brace when generating tags for treeview;
  • fixed escaping of treeview's row id;
  • fixed escaping of treeview's row text (first column);
  • fixed blocking of pixelbuffer demo.

• TCL/TK interpreter (version >= 8.6) https://www.tcl.tk

• alexandria;
• cl-ppcre-unicode;
• cl-lex;
• cl-yacc;
• clunit2;
• cl-colors2;
• named-readtables.

All of the above libraries are available on quicklisp.

• tklib https://core.tcl-lang.org/tklib/home
• tkimg https://sourceforge.net/projects/tkimg/

Optionally you can install the library getting the source code from project's repository.

All these widget, written in common lisp, are defined in file src/nogui-mw.lisp.

Some more widget in nodgui derive from wrapping and, in some case, extending the widget set contained in tklib

To use these widget in nodgui tklib must be installed on your system, fortunately this library is widely available at least on GNU/Linux.

On Debian just a couple of commands are needed:

$ su -
(root)# apt-get install tklib

The default TK canvas widget is good at drawing graphics primitives but the performance when trying to render a block of pixels is very poor.

This library is able to embed an SDL window to allow pixels rendering fast enough to get (with the help of compiler optimization) a decent animation at 60 frames per seconds.

Embedding SDL allow also for 3D hardware accelerated rendering, using openGL.

Color name from library cl-color can be used as follows:

• with a reader macro (#%...%) at read time:

  (named-readtables:in-readtable nodgui.syntax:nodgui-syntax) ; do not forget that!
  
  [...]
  
  #%red%
  

  at runtime using:

  (rgb->tk cl-colors:+red+)
  

  the list of supported colors name can be found in: this file.
