Pansy

My own programming language, currently under development

How to start

You need to have Python 3.6+ installed. If you haven't, go to Python and install the latest version.

Once you have Python setup, you need to clone this repository and open a terminal inside the folder. Then you must type:

C:\Users\...\Pansy > python shell.py

You should see:

Pansy> 

You can exit anytime using the command:

Pansy> exit

Now you are ready to start! 😄

How to run your file

Let's imagine you want to run the code that is in the dir: examples/HelloWorld/code.pansy
You just need to use the command:
Pansy> run("examples/HelloWorld/code.pansy")

Features

Assigning variables

var x = <value>

Comments

@ This a one line comment

Data types

Currently there are 4 data types: Integer, Float, String and List.

Integer

var x = 1

Float

Pansy> var x = 5.0

String

var x = "This is a string"

List

var x = [1,2,3]

Operations

• Sum (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)
• Int Division (//)
• Remainder (%)

Comparators

• Equal (==)
• Inequal (!=)
• Greater than (>)
• Less than (<)
• Greater than or Equal to (>=)
• Less than or Equal to (<=)

If Statements

var x = 0
if x < 0:
  print("You need more!")
elif x > 0:
  print("You need less!")
else:
  print("Correct!")
end

For Loops

for i=0 to 10:
  print(i)
end

for i=0 to 10 step 2:
  print(i)
end

While Loop

var x = 0
while x < 10:
  print(i)
  var i = i + 1
end

Functions

func double(n) {
  var n = n * 2
  return n
}

Pansy comes with some built-in functions (more on the way 😉):

• print(arg) - Prints arg on the screen
• input() - Waits for the input of the user
• is_number(arg) - Returns 1 (True) if arg is a number or 0 (False) if not
• is_string(arg) - Returns 1 (True) if arg is a string or 0 (False) if not
• is_list(arg) - Returns 1 (True) if arg is a list or 0 (False) if not
• is_function(arg) - Returns 1 (True) if arg is a function or 0 (False) if not
• append(arg1, arg2) - Appends arg2 to the list arg1
• pop(arg1, arg2) - Pops the element at the index arg2 of the list arg1
• extend(arg1, arg2) - Joins to lists together
• get(arg1, arg2) - Gets the element at the index arg2 of the list arg1
• run(arg) - Runs a program from a file with the extension .pansy
• len(arg) - Returns the length of the list arg
• to_str(arg) - Transforms arg to a string if possible
• to_int(arg) - Transforms arg to a integer if possible
• to_float(arg) - Transforms arg to a float if possible
