Sure there is: (defvar hex-display-table-prefix "\\") (defvar hex-display-table-suffix nil) (defvar hex-display-table (let ((table (make-display-table)) (char ?\x00)) (while (<= char ?\xFF) (unless (equal char ?\n) (aset table char (vconcat hex-display-table-prefix (format "%02X" char) hex-display-table-suffix))) (setq char (1+ char))) table)) (setq buffer-display-table hex-display-table) > No I'm not talking about hexl mode or whatever. -- Kevin ^ permalink raw reply [flat|nested] 3+ messages in thread

I.e. I am only unhappy about \200...\377. Kevin> (setq buffer-display-table ... I believe the solution instead lies in a new variable that controls a deeper down C code item, without the user needing to fiddle with buffer-display-table nor standard-display-table etc. No need to target any specific characters, all I am saying is deep down when emacs feels the urge to send a octal representation to the screen, it sends instead a hex representation. I am saying "emacs old buddy, you are doing a perfect job at selecting what bytes or characters or whatever to send to the screen as (the four byte) \222, etc. Now just allow the user the choice of how he wants them shown: hex, octal (current), binary, decimal, etc." Also there should be a way to paste the e.g., \222 that we see into another buffer as the four bytes, not one, without having to resort to emacs -nw and the mouse. (By the way (compile "perl -e 'for(0..99999){print chr}' 2>&-" nil) causes error in process filter: font-lock-fontify-keywords-region: Stack overflow in regexp matcher. Probably for good reason. But that is not what I'm worried about here.) ^ permalink raw reply [flat|nested] 3+ messages in thread
