These days while doing my Operating System Project (PROSO) I rescued a project I made a year and a half ago, while I was learning x86 ASM. It can output the resulting stack representation to the console (text) or html which looks far better. It may be useful if you’re learning x86 ASM. Syntax used in the output is the AT&T one, which is the gnu standard.
If you want to check it, you can look here.
