Hashtag

Hashtag is an esoteric programming language designed by User:Broxol to be a pain in the butt to program. It is also designed to be unreadable to anyone who dares try to come across it without knowing anything.

Just to give you a taste, here is Hello, World written in Hashtag:

code = "f##:_A>>>>>>>#a>>>>#>>>>>>>##>>>#N>>>>>>>>>>#>>#n----#a>>>>>>>>>>>>>>#>>>#------#a>>>#:f!:p"

FUNCTIONS

When editing string

Syntax	Function
<	Decrements pointer by one
#	Appends what pointer is looking at to string
!	Deletes top item of string
=	Resets the string
a	Sets the pointer to 0 (lowercase letters)
A	Sets the pointer to 26 (capital letters)
n	Sets the pointer to 52 (numbers)
N	Sets the pointer to 62 (symbols/extra)
>	Increments pointer by 1

Functions

Syntax	Function
f##:…:	Changes the string
f@#:…:	Creates a variable (string) and sets it to value …
f!:p	Prints string
f!:@	Prints variable string
f&&@	Allows user input, sets it to int and puts it in variable string
f&&#	Allows user input and sets it to str
??(-)	Jumps to variable string. If - is appended, jumps to end of program.
*@:…:(+-*/%)	Does operations between var string and var …
?:…:(~$>)……;	If statement, checks var string and … string, if false it skips over …… until it hits ;
