Interpreted Languange Run in Python

1. Introduction

This is a simple interpreted language run in Python. This project also includes Simple Text Editor and Interactive Terminal. It supports the following features:

1. Variable declaration and assignment

Example:
a = 1
b = 2

2. Arithmetic operations

Example:
a = 1 + 2
b = 3 - 4
c = 5 * 6
d = 7 / 8
e = a + b * c - d

note: string arithmetic is the same as python

3. List declaration and assignment

Example:
a = [1, 2, 3]

4. Conditional statements

Example:
if a > b
    out(a)
else
    out(b)
end

5. Loop statements

i = 0
while i < 10
    out(i)
    i = i + 1
end

6. Function declaration and call

fn add(a, b)
    return a + b
end

7. class declaration and instantiation

class A
    fn init(a, b)
        this.a = a
        this.b = b
    end
end

C = A(1,2)

8. Comments

# This is a comment

9. Import other file

import [path], workspace is the same folder as the file

10. Built-in functions

out(a) # print a
in(a) # read input and store in a
sizeof(a) # return the size of list a
class.funct_list() # return the function list of class
class.var_list() # return the variable list of class

NOTE: it has goto statement, but dont use it. its work in file but not in interactive terminal. And i hate it so i'm not gonna work on it. So dont use it. EVER. Text editor supports the following features:

1. Open folder and file
2. Save file
3. Run file
4. Syntax highlighting
5. Auto Save

2. Pre-requisites

2.1. Python

You need to install Python 3.1x or above to run this program. You can download Python here.

2.2. customtkinter

You need to install customtkinter to run this program. pip install customtkinter

2.3. ipython

You need to install ipython to run the Text Editor. pip install ipython or you can change the code in App.py to use python instead of ipython. But there's some problem where the early half of the output get deleted. I don't know why.

2. How to use

2.1. Run the program

To run the interpreter, you can use the following command:

py interpreter.py [file_name] # doesn't care about extension
py interpreter.py -i [file_name] # run file in interactive mode 
py interpreter.py to run interactive terminal

To run the text editor, you can use the following command:

py App.py
