Hafni is a project mainly written in CLOJURE and PERL, it's free.
Hafni is a java swing wrapper for the clojure language focusing on how components change.
=head1 Hafni
Hafni is a java swing wrapper for the clojure language focusing on how components change. This does not only mean that the content displayed should be easy to change, but also that events coming from that content should be handled in a convenient way.
=head3 Example
This is a small taste of Hafni, for a more thorough explanation of the parts of Hafni, see Usage below. The following example comes from C<Hafni.test.swing.action/button-test2>
(frame :content (comp-and-events (button :text "") :act (flow (output-arr this :text) >>> (arr #(str % "")) >>> (input-arr this :text))) :size 200 200 :dont_exit_on_close)
This creates a frame (a window if you so will), with a button as content, size 200x200 and which doesn't close when the frame is closed (useful when working in the repl).
(comp-and-events (button :text "") :act (flow (output-arr this :text) >>> (arr #(str % "")) >>> (input-arr this :text)))
We first create a button with the text "*".
(button :text "*")
Then, when the button is pressed, the buttons text is extracted, another "*" is added to the end of that text, and set as the current text of the button.
(flow (output-arr this :text) >>> (arr #(str % "*")) >>> (input-arr this :text)))
What happens is that C<(output-arr this :name)> receives the current text, which is then sent to the function C<#(str % "*")> (the C can be ignored for now). The result of that function is then sent to the buttons text with C<(input-arr this :text)>. The result is that the text of the button changes in the following way:
"" "" "" "****"
To accomplish this, Hafni uses the datatypes I
