What is Dinfio?

Dinfio is a high-level, general-purpose, interpreted, minimalist, simple, and open source programming language. Dinfio's design philosophy is "code simple!". Here is an example of "Hello world" programme in Dinfio:

start
    writeln("Hello world!")
stop

Or just:

writeln("Hello world!")

Dinfio supports multiple paradigms, including imperative, procedural, object-oriented, and event-driven programming. Dinfio comes with great built-in modules, like Standard I/O, String manipulation functions, Mathematical functions, Date and Time, Regular expression, File I/O, Graphical User Interface (GUI), HTTP requests, JSON functions, and more.

So, without further ado, let's get started!

1. Download and install the Dinfio Programming Language
2. Launch your favourite text editor and code this:

   start
       var name = "Chérie"
       writeln("Hello, my name is " & name)
   stop

   
   
3. Save your code with .fio extension, for example save it as hello.fio in your home directory
4. Launch Terminal/Command Prompt and type dinfio hello.fio. You'll see the greeting:

   Hello, my name is Chérie

   
   
5. Voilà! You have created your first programme in Dinfio.

Examples

Here is an example of beautiful GUI programming in Dinfio with very simple lines of code:

' GUI Programming
 
import gui
 
start
    window = gui_window("Hello!", 260, 130)
 
    label = gui_label("Your name: ", window, 20, 20)
    textbox = gui_textbox("", window, 100, 17)
    button = gui_button("OK", window, 100, 56)
 
    button.addevent(event.click, button_click())
    window.show()
stop
 
function button_click()
    messagebox(textbox.gettext())
stop

Output:

It's very simple, isn't it? You can even find more great and fun examples on the Dinfio Playground and on the GitHub Repository.
