AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

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

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA is an stack-based esoteric programming language made by User:SzszszszszszszsZ in which the only letter is the letter "A" (except strings and variable names). Commands are disambiguated with fonts. The number of A's in the title corresponds to the number of instructions this esolang has (excluding extensions).

Instructions

Newlines separate commands, as most programming languages do.

Stack

Font	Command	Represented as
Arial	Pushes / enqueues the argument next to the A onto the stack / queue.	A [argument to push]
Calibri	Pops / Dequeues the top value from the stack / queue.	A
Roboto	Duplicates the top of the stack.	A
Helvetica	Swaps the top two values of the stack.	A
Lato	Reverses whole stack.	A

I/O

Font	Command	Represented as
Verdana	Pops the top value of the stack and prints it, without a newline. The top value of the stack must be a string for it to be printed. A newline is represented as \A. Unlike most programming languages, the last \A goes outside the quotes.	A
Tahoma	Asks user for input and pushes it onto the stack as a string.	A

Control Flow

Font	Command	Represented as
Times New Roman	Starts and ends an if block.	A [condition] A code here A
Georgia	An "else" in the if block.	A [condition] A code here A A more code here A
Garamond	Starts and ends a while block.	A [condition] A code here A
Segoe UI	For loop. Start and end must be integers.	A [start] [end] A code here A
Book Antiqua	Break out of loop. Causes an error when not in a loop.	A
Palatino	Halts program. Not having this causes an error.	A

Operations

Numbers in AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA are represented with a string of A's. One can use any font, but it's recommended to use the default font (Arial or Calibri).

1 = A
2 = AA
3 = AAA
5 = AAAAA
-2 = -AA
3.14 = AAA.A.AAAA
1.23456789e+20 = A.AA.AAA.AAAA.AAAAA.AAAAAA.AAAAAAA.AAAAAAAA.AAAAAAAAA.A+AAAAAAAAAAAAAAAAAAAA
0 = -

Font	Command	Represented as
Montserrat	Addition. Can only be used with integers or floating-point numbers.	A [num 1] [num 2]
Consolas	Subtraction. Same restrictions as A.	A [num 1] [num 2]
Courier New	Multiplication. Same restrictions as A.	A [num 1] [num 2]
Lucida Console	Division. Division by zero causes an error. Same restrictions as A.	A [num 1] [num 2]
Monaco	Modulo. Modulo by zero also causes an error. Same restrictions as A.	A [num 1] [num 2]
Ubuntu	Tests for equality. Can only be used by replacing [condition]. Trying to push the result directly causes an error.	A [expression 1] [expression 2]
Gabriola	Greater than. Same restrictions as A.	A [exp 1] [exp 2]
Inter	Gets top of stack.	A

Conversions

Font	Command	Represented as
Poppins	Converts to integer.	A [argument]
Baskerville	Converts to string.	A [argument]
Agency FB	Converts to a floating-point number.	A [argument]

Variables

Font	Command	Represented as
Comic Sans MS	Declares a variable.	A [variable name]
Brush Script MT	Assigns to a variable.	A [variable name] [expression]
Lucida Handwriting	Gets a variable's value.	A [variable name]

Other

Font	Command	Represented as
Impact	Comment	A [whatever]
Cambria	LaTeX formula. It then gets evaluated, and the result gets pushed onto stack. When there is an error in the expression, an error occurs. (duh)	A [formula]
Noto Serif	Toggle queue mode.	A

Croscore font extensions

ChromeOS has different fonts for fallback defaults. They are normally not used in AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA, since most computers use Windows. These are the instructions:

Font	Command	Represented as
Arimo	Roll. Works like the roll in Piet.	A [num 1] [num 2]
Tinos	Switch-case.	A A A code here AA A more code here AAA A more code here ... AAAA...AAAA A when all else has failed A
Cousine	Exponentiation.	A [num 1] [num 2]
Caladea	Random number. Start must < end.	A [start] [end]

Carlito is the same as Lato.

Support for custom fonts

There are numerous fonts to choose from that correspond to various commands. You can mod the language to, say, Wingdings 2 to do the crazy operation in Malbolge on the 3rd item on the stack

Just so you know, you should install the fonts first on your device if you haven't already.
