Oops, sorry to mislead you. I was wrong about Unix ed. I knew it had powerful regex and line addressing, I figured it had character addressing/cursor positioning too. CP/M ed has basic search and replace, but most work is done with cursor movements.
- DonHopkins 9y agoITS Emacs has "glass tty" support that responded to keystrokes exactly as normal, but only showed one current line by repainting it without using any fancy control characters or escape codes, just backspace, carriage return and line feed. (That's what it meant to be "glass".) So ^L would refresh just the current line, and you could ^N down through a file to print it out line by line. http://www.finseth.com/craft/#c2 http://www.finseth.com/craft/#c2
