Here is why some old grumpy -terminal users wants its backspace to be how he feels it: - - Well, I am going to comment why I want to change the behaviour - of this key. When ASCII was defined in 1968, communication - with computers was done using punched cards, or hardcopy - terminals (basically a typewriter machine connected with the - computer using a serial port). ASCII defines DELETE as 7F, - because, in punched-card terms, it means all the holes of the - card punched; it is thus a kind of 'physical delete'. In the - same way, the BACKSPACE key was a non-destructive backspace, - as on a typewriter. So, if you wanted to delete a character, - you had to BACKSPACE and then DELETE. Another use of BACKSPACE - was to type accented characters, for example 'a BACKSPACE `'. - The VT100 had no BACKSPACE key; it was generated using the - CONTROL key as another control character (CONTROL key sets to - 0 b7 b6 b5, so it converts H (code 0x48) into BACKSPACE (code - 0x08)), but it had a DELETE key in a similar position where - the BACKSPACE key is located today on common PC keyboards. - All the terminal emulators emulated the difference between - these keys correctly: the backspace key generated a BACKSPACE - (^H) and delete key generated a DELETE (^?). - - But a problem arose when Linus Torvalds wrote Linux. Unlike - earlier terminals, the Linux virtual terminal (the terminal - emulator integrated in the kernel) returned a DELETE when - backspace was pressed, due to the VT100 having a DELETE key in - the same position. This created a lot of problems (see [1] - and [2]). Since Linux has become the king, a lot of terminal - emulators today generate a DELETE when the backspace key is - pressed in order to avoid problems with Linux. The result is - that the only way of generating a BACKSPACE on these systems - is by using CONTROL + H. (I also think that emacs had an - important point here because the CONTROL + H prefix is used - in emacs in some commands (help commands).) - - From point of view of the kernel, you can change the key - for deleting a previous character with stty erase. When you - connect a real terminal into a machine you describe the type - of terminal, so getty configures the correct value of stty - erase for this terminal. In the case of terminal emulators, - however, you don't have any getty that can set the correct - value of stty erase, so you always get the default value. - For this reason, it is necessary to add 'stty erase ^H' to your - profile if you have changed the value of the backspace key. - Of course, another solution is for st itself to modify the - value of stty erase. I usually have the inverse problem: - when I connect to non-Unix machines, I have to press CONTROL + - h to get a BACKSPACE. The inverse problem occurs when a user - connects to my Unix machines from a different system with a - correct backspace key. - - [1] http://www.ibb.net/~anne/keyboard.html - [2] http://www.tldp.org/HOWTO/Keyboard-and-Console-HOWTO-5.html - - -## But I really want the old grumpy behaviour of my terminal - -Apply [1]. - -[1] https://st.suckless.org/patches/delkey - - -## Why do images not work in st using the w3m image hack? - -w3mimg uses a hack that draws an image on top of the terminal emulator Drawable -window.
