BracketsLang

BracketsLang is esoteric programming language invented in 2021 by user PoetLuchnik to show that brackets are better than Python tabs. Code is a sequence of atoms and blocks of sub-code. The program is always curly brackets block. Each block contains sub-code and has its own accumulator, which is zero at the beginning. Atoms have no code in, and they works with parent block accumulator. Accumulator is byte value [0..255]. Brackets are code, everything else is notes.

What do the brackets do

case	description	c-like
()	print accumulator as ASCII character	putchar(accumulator);
[]	increase accumulator by the ASCII value of entered character	accumulator += getchar();
<>	set accumulator to null	accumulator = 0;
{}	increment accumulator	accumulator++;
(sub-code)	store parent accumulator by address in own accumulator	RAM[accumulator] = parent_accumulator;
[sub-code]	load value by address in accumulator and add it to parent accumulator	parent_accumulator += RAM[accumulator];
<sub-code>	when ends if the accumulator not equals 0 then ending parent block immediately	subcode(); if (accumulator != 0) break;
{sub-code}	repeats sub-code endlessly, subtract accumulator from parent accumulator if ends	ui8_t T = 0; while(!isbreak) T = subcode(); parent_accumulator -= T;
