quickchat

Have you ever wanted to trash talk people in Rocket League, but didn't want to type on your keyboard? Is a simple quick chat option not enough? Well now you can, using only a cryptic series of quick chat options! It might take a while, and they might never get what you were doing, but you'll know. And that's all that matters.

Getting Started

Either download the 'quickchat.exe' from the releases or build from source using CMake. Then, run .\quickchat <source_file>.qc in the command-line. There is an REPL, but loops don't work yet.

Language

This is based on brainfuck so all the same commands are here, plus a few extra. In quickchat, multiple tapes can exist. Therefore, all commands require the name of the tape to act on.

Commands

Command	brainfuck	Description
<NAME>: I got it!	>	Increment tape pointer.
<NAME>: Defending...	<	Decrement tape pointer.
<NAME>: Nice shot!	+	Increment value at pointer.
<NAME>: No problem.	-	Decrement value at pointer.
<NAME>: Take the shot!	[	Begin loop if value at tape != 0.
<NAME>: What a save!	]	End loop, jump back to beginning.
<NAME>: Incoming!	,	Accept one byte of input.
<NAME>: Calculated.	.	Output one byte.
<NAME>: Great pass!		Copy the current value from the tape indexed at the current value's position.
<Name> joined the match		Create a new tape with the name .
<Name> left the match		Delete the tape with the name .

Syntax

Each line must start with an identifier, followed by either a join command, a leave command, or a command. Commands are seperated by newlines.

1. <Name><SINGLE_SPACE><JOINED||LEFT>\n
2. <NAME>:<SINGLE_SPACE><COMMAND>\n

There's no way to comment the code because I believe code should be self commenting. See the 'Hello World' example below for instance.

Hello World!
