This is a follow-up to this question: I'm trying to create a keyboard shortcut for the terminal file manager ranger, in order to jump from the zsh prompt into the file manager with a single keystroke. I was following the linked answer, adding this to my .zshrc:



run_ranger () echo; ranger; zle redisplay 
zle -N run_ranger
bindkey '^f' run_ranger


The key binding itself works, however ranger fails to start with Error: Must run ranger from terminal. I had a look at the ranger code (Python) and it performs the common check sys.stdin.isatty() to verify that is has a TTY stdin. How can I modify the zle widget so that stdin is properly set?

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
