Introduction

SunSip, SLWNSNBP, or Simple Language Which Name Shall Not Be Pronounced, is a Turing Complete, Practical, Whitespace Insignificant, Simple programming language (which name shall not be pronouced). SunSip is based on variables, with a simple concept and syntax, designed to be beginner friendly. There are goals to turn it into a golfing language (by shortening instructions, et cetera.,) but that is currently just a thought. The slogan is, 800 lines of code, for a good coding experience. This is a project that I am working on in order to apply for a certain science club. You can refer to the Research section for details.

Installation

First, you have to install python via python.org. You might already have it installed, or you might not.

SunSip can be installed from source or via pip. To install SunSip via pip, use:

pip install SunSip

Or whatever way you use pip.

Execution (Installation via pip)

SunSip code can be named with any extension, although the preferred extension is either none, .txt, .sunsip, .snsp, or .slwnsnbp.

After writing the SunSip code, you can execute it using

sunsip path-to-program [options]

For a list of options, refer to the help menu accessible via python -m SunSip --help.

Execution (Installation from source)

To install SunSip from source:

1. Clone this repository
2. Make sure you have Poetry installed
3. Run poetry install in the cloned repository

You can then run sunsip and sunsip-syntax-highlight as normal.

Test Your Installation

If you haven't installed SunSip, do so by referring to the Installation Section.

First, create a folder on your desktop called hellosnsp. This folder will store all of your programs. Create a text file named firstprogram.txt inside the folder, and write:

comment this should print hello world
set to "Hello, World! "
out

Execute the file (see the Execution Sections). It should produce the output:

Hello, World! 

Debugging

If you need to debug your code, use the -d flag. This will output the parsed program first:

Program:
[['#', 'math support'], ['', ''], ['set', '180 to 180'], ['set', '5 to 5'], ['set', '4 to 4'], ['set', '1 to 1'], ['set', 'number to 1'], ['set', 'to "'], ['out', ''], ['set', 'empty to " "'], ['', ''], ['set', 'to "'], ['calc', 'type number'], ['calc', 'type last number'], ['set', 'length to'], ['calc', 'subtraction 5 length'], ['set', 'i to'], ['set', 'stack to []'], ['calc', 'push stack number'], ['set', 'stack to last'], ['', ''], ['calc', 'push stack empty'], ['set', 'stack to last'], ['calc', 'subtraction i 1'], ['set', 'i to'], ['calc', 'less i 1'], ['calc', 'multiplication last 4'], ['skip', ''], ['', ''], ['set', 'to 10'], ['back', ''], ['', ''], ['calc', 'factorial number'], ['calc', 'push stack last'], ['set', 'stack to'], ['set', 'to "'], ['calc', 'join stack'], ['out', ''], ['calc', 'addition number 1'], ['set', 'number to'], ['set', 'to 40'], ['calc', 'greater number last'], ['calc', 'multiplication last 4'], ['skip', ''], ['', ''], ['set', 'to 36'], ['back', ''], ['', ''], ['set', 'to "'], ['out', '']]

and after each line will print the current line, current instruction, current parameters, and current variable values.

Current Line: 49

Instruction: out

Parameters: 

Variables: {'180': 180, 'last': '', '5': 5, '4': 4, '1': 1, 'number': 41, 'empty': ' ', 'length': 2, 'i': 0, 'stack': [40, ' ', ' ', ' ', 815915283247897734345611269596115894272000000000]}

Suppressing warnings

Take the example program,

# math support

set 180 to 180
set 5 to 5
set 4 to 4
set 1 to 1
set number to 1
set to "
out
set empty to " "

set to "
calc type number
calc type last number
set length to
calc subtraction 5 length
set i to
set stack to []
calc push stack number
set stack to last

calc push stack empty
set stack to last
calc subtraction i 1
set i to
calc less i 1
calc multiplication last 4
skip

set to 10
back

calc factorial number
calc push stack last
set stack to
set to "
calc join stack
out
calc addition number 1
set number to
set to 40
calc greater number last
calc multiplication last 4
skip

set to 36
back

set to "
out

When you execute it, it will cause warnings, and output the following:

WARNING: UNEXP LINE 1



WARNING: IMPL TYPE CONV AT LINE 37


WARNING: IMPL TYPE CONV AT LINE 37

(with warnings in red.) Warnings are parts where your program could've gone wrong. To suppress them, for cleaner output, use the -w flag:

It is not recommended to turn off warnings while debugging.

Contributing

I want to contribute! How?

Method 1, create a pull request. Method 2, edit directly. Method 3, open an issue.

We accept contributions that add functionality, fixxes bugs, or raises bugs. However, code editors must create a pull request or open an issue, and the issue must be passed before they do the editting.
