symbolang 0.1.3

A simple 2D programming language.

Symbolang

a 2-dimensional, interpreted, programming language, inspired by befunge

intro

The main concept of a Symbolang program is the 'pointer'. the pointer is the imaginary cursor that executes each character one by one.

Variable scope

This is a stack based language, (at least for now)

There aren't really any variables, but you are able to push and pop values to and from the stack.

Syntax

Symbol	Function
>	Makes the pointer start moving left
<	Makes the pointer start moving right
^	Makes the pointer start moving up
v	Makes the pointer start moving down
?	Random pointer direction
h	horizontal if statement; pops value from stack, if value is 0, set direction to right, if it's anything else set it to left.
"	toggles stringmode. if on, every character's ascii value will be pushed to the stack.
	(single space) go to the next character
,	pops value from stack and prints ascii character corresponding to that value.
.	pops value from stack and prints it.
1-9	pushes corresponding value to stack.
/, *, +, or -	pop two values from stack (a, then b), and then performs the operation on a and b and pushes result to stack.
I	(CAPITAL I) gets a number or character from user, and pushes it to the stack.

Table of functions

Use

simply clone the repo, git clone https://github.com/thelegendofmario/symbolang.git, then, place your .symb file into the directory, and in your terminal, type symbolang [argument] [your-file-here].

Arguments

if you run it with --debug, it will print debug info. docs on what it displays coming soon!

Changelog

• v0.1.0
  • Made a debug mode. I feel like this is the first real version
• v0.1.2
  • HUGE quality of life upgrade :)
  • programs usually looked like this: > 0 . 0 <, but now they look like this: >0.0<
• v0.1.3
  • now this can be run as an actual CLI app.

Roadmap

• At some point, it would be AMAZING if this had an interpreter in a compiled language (instead of being interpreted to be interpreted).
• up and down movement of cursor <- completed
• interactive REPL would be awesome
• a tulip port
