Dinfio Programming Language

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, let's get started!

Download and install the Dinfio Programming Language

Launch your favourite text editor and code this:

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

Save your code with .fio extension, for example save it as hello.fio on your home directory
Launch Terminal/Command Prompt and type dinfio hello.fio. You'll see the greeting:
```
Hello, my name is Chérie
```
Voilà! You have created your first programme using Dinfio.

' 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()
