G Sharp

The title of this article is not correct because of technical limitations. The correct title is actually G#.

G# is a esolang with the syntax similar to Python and C. Created by User:Ractangle

Syntax

Commands

Command	It's action
make <classname>;[...]	Creates a class,
print <string>	Prints a string.
assign <varname> as <varval>	Creates/Edits a variable.
loop if <condition>	while statement.
if/else/orif	Condition command.
input	Gets user input
#	One-line comment
###...###	Multi-line comments
return	turns a class into a function

Classes

A Class should folow this structure:

make a_name_here;[
    # Commands here
]

Variables

The variables NEED to be assigned at the top.

Also there are types:

Type name	Type symbol
String	$
Integer	#
Boolean	?
Ticker	+

And if you want to edit a variable. You just write:

assign $a to anything

And if you want to assign more variables with the same value, write:

assign a;b to anything

This implies to the variable edition as well

Functions

Functions are basically the same as Classes. "But how do make functions?" you may ask. Simple. Just add a return command and some arguments:

return {written}{like}{this}

And to use the argument on a function, We just write:

f[name]{the argument used in your function}

So the function should look like this:

make function; [
    return {arg}{another arg}
    # Commands here
]

And to call a function:

f[function]{Hello, ||world!}

And now you're probably saying, "So if an argument is used, it's automatically an required argument, right?"

Yes, but you can turn off the "require" option if it's not really required:

make fun [
    return{arg#r=0}
    # Commands here
]

Also fun fact:If there are no classes but only functions, the program will run the latest declared function, argument are automatically ignored (if the command-line args for those args not added)

Errors

If no main class is found in the code:

NO MAIN CLASS FOUND IN CODE

If a built-in function gets overwritten by another function:

CANNOT OVERWRITE BUILT-IN

Examples

Hello World

make main;[print("Hello World\n")]

Cat program

string assign a as input
make main;[print($a)]

A+B problem

integer assign a;b as input
make main;[print(#a+#b)]

Infinite loop

boolean assign l to 1
make main;[ loop if 1 [1] ]

Truth-machine

integer assign i as input
make main;[
    if #i=0 [print(0)]
    loop if 1 && #i!0 [print(1)]
]

Empty Program

make e; [return{}]

99 bottles of beer

integer assign bot as 99
make main;[
    if #bot is 1;[ print(#bot," bottle of beer on the wall,\n",#bot," bottle of beer.\nTake one down, Pass it around,\nNo bottles of beer on the wall,\n") ]
    else [ loop if #bot ! 1;[ print(#bot," bottles of beer on the wall,\n",#bot," bottles of beer.\nTake one down, Pass it around,\n");assign #bot as #bot-1;print(#bot," bottles of beer on the wall,\n\n") ] ]
]
