Without actually trying it, this may or may not help. But I'd done a really tricky prompt once that included various escape sequences (such as to set the window title). I found I had to do all of those first, followed by a carriage return character and then the characters I wanted to see actually on the prompt. One problem is (at least with old ksh) that the inline editor modes simply count characters to know what column they're in; they know nothing of escape sequences. So the characters in an escape sequence are counted towards the total number of columns used by the prompt, but that probably doesn't match up with what you see on the screen. The carriage return character returns the shell's column count back to zero apparently, so that hid from its count all the stuff that came before the carriage return. Even then, there were some unusual cases where it could look a bit ugly on the screen, but mostly that trick took care of my problems doing what I wanted to with the prompt. -- This message posted from opensolaris.org
