it's perfect for you, @TùxCräftîñg

TùxCräftîñg

ಠ_ಠ

is vim TC?

because the number of macros is limited

Mᴀʀs Uʟᴛᴏʀ

@TùxCräftîñg It is

@TùxCräftîñg macros = vim functions, I think

you can execute as many actions as you want

TùxCräftîñg

recursive macros is the only way to loop

so "loops" with a high nest level are tricky/impossible

@TùxCräftîñg four asm instructions: xor eax eax eax

TùxCräftîñg

eax is a register, not a instruction, and xor take only 2 operands AFAIK

Anonymous

@TùxCräftîñg It's a single instruction, in the format instruction operand1 operand2 result

TùxCräftîñg

@Mego eax imply x86 assembly, and AFAIK xor take only 2 operands

Anonymous

In C-like notation, it's equivalent to eax = eax ^ eax, which is a fancy ASM way of saying eax = 0, without needing to load a 0 and store it.

Anonymous

9:13 AM

@TùxCräftîñg x86 ASM isn't the only assembly language to use eax

mınxomaτ

@TùxCräftîñg It's just a pun of the very common clean and reuse of EAX.

TùxCräftîñg

@Mego so what other architecture use it?

Mᴀʀs Uʟᴛᴏʀ

@TùxCräftîñg x64 uses it to refer to the lower 32 bits of rax (iirc)

TùxCräftîñg

i know >_>

Anonymous

@TùxCräftîñg Not necessarily architecture - lots of assemblers assemble x86 machine code, and some support shortcuts/macros (like xor eax ebx ecx instead of mov edx ebx; xor ebx eax; mov ecx ebx; mov ebx edx;)

adding ascii io and stuff

perhaps to utf-8

the ~ is so useless: why is it even on my keyboard

TùxCräftîñg

@DestructibleWatermelon ~ is the bitwise invert operator
