In all bash 3.2 versions I've tried so far, there's a problem with vi history editing. If you hit escape and k to go up, the cursor is offset in the line by the width of the prompt. No amount of line redrawing can fix this, and when you exit back to the prompt, the portion that was offset is still there on the line. bash-3.1_p17 doesn't have this problem.
Jakub: What does this have to do with vim? It's a bash issue, and shows up if vim isn't even installed.
Uh, yeah... this is totally not related to vi/vim. It's a set of key bindings for readline. So, this is a bash/readline problem. Re-assigning to base-system.
Daniel, do you have colour prompt? Then this could be related bug 155369 ...
I do, indeed, have a color prompt. My prompt is: PS1="^[[32;1m[\t \h] ^[[34;1m\W^[[0m> " However, I have a ~amd64 system, so I have those fixes versions already. I have sys-libs/readline-5.2_p2, and I still had the problem with app-shells/bash-3.2_p15 (although I don't appear to have put 3.2_p10-r1 into my package.mask, so maybe that one worked? I'll emerge it and try...)
Nope, 3.2_p10-r1 still exhibits the same problem...
3.2_p17 still has the problem.
Daniel, could you please describe the problem another time? Just explain steps you do and what goes wrong? Personally, I do not see anything unusual.
Sure. Here's what I do: [15:19:55 athena] ~> ls evolution-2.11.1-more-64-bit.patch evolution-2.9.91-cal-reply.patch (That's all one one line). It doesn't matter what the command is; any command that results in more than 80 char on the screen, ie that causes the line to scroll with "<" on the left side, is sufficient. Then, after the command is run, I hit <esc>k to go up one line into history. The cursor is somewhere in the middle of the line, but it think's it's at the beginning. The line does not redraw correctly, even with <ctrl>-l. As I move the cursor right and left, it updates the character under the cursor, but it reverts to the wrong one after any kind of redraw. This makes command line history completely useless to use. If this isn't clear enough, I can try to make a screencast of the problem... My .profile sets these related settings: shopt -s histappend export HISTCONTROL="erasedups" PS1="^[[32;1m[\t \h] ^[[34;1m\W^[[0m> " set -o vi I have bash-completion enabled. My .inputrc contains this: set horizontal-scroll-mode On set editing-mode vi set completion-ignore-case On bash 2 is fine; bash 3.0.x is fine. bash 3.1 had the problem briefly (p8 and p10 failed) but 3.1_p17 is fine, and what I'm using now. bash 3.2.x all have the problem. I've tried p9 p9-r1 p10 p10-r1 p15 p15-r1 p17, all of which fail. I have readline-5.2_p4.

Daniel, can you reproduce your problem with horizontal-scroll-mode off? Also do you have \[ \] around color specifiers in your PS1? Try this (I've substituted ^[ with \033 (so you can just cut and paste) and putted \[ \] around colors) : PS1="\[\033[32;1m\][\t \h] \[\033[34;1m\]\W\[\033[0m\]> "
horizontal-scroll-mode seems to make no difference; with it on or off, all of my investigation below was the same. In addition, I tried both with and without vi history mode, and I had similar (although not identical, because emacs mode positions the cursor at the end of the line, while vi mode positions it at the beginning of the line) problems with both. No, actual information. That prompt is actually worse. I get the same problem (both with horizontal-scroll-mode on and off), but the cursor is over the first : in the time, not on the end of the line like with my normal prompt: [12:04:54 athena] ~> ^ Cursor is here. It does, however, seem to be prompt related, because the default prompt doesn't cause this problem, just my prompt. Okay, a litte more investigation. My original prompt, with \t changed to \A still causes the problem. The stock gentoo prompt, with \u changed to \t causes the problem; however, with \u changed to \A, there is no problem. My original prompt with \t changed to \A *does* cause the problem. Here's a prompt that works: PS1='\[\033[01;32m\]\A \h\[\033[01;34m\] \w \[\033[00m\]> ' Here's one that fails: PS1='\[\033[01;32m\]\t \h\[\033[01;34m\] \w \[\033[00m\]> ' Just for fun, I tried \D. Using seconds fails: PS1='\[\033[01;32m\]\D{%H:%M%S} \h\[\033[01;34m\] \w \[\033[00m\]> ' But using no seconds succeeds: PS1='\[\033[01;32m\]\D{%H:%M} \h\[\033[01;34m\] \w \[\033[00m\]> ' Interestingly, by accident, I typoed the prompt, and this works fine: PS1='\[\033[01;32m\]\D{%H:%M%S} \h\[\033[01;34m\] \W \[\033[00m\]> ' (note the lack of : between %M and %S) Adding that : back in causes failure. For now, I'm using the prompt that works above, but I'd like to have my seconds back on the display. One final thing: I'm using gnome-terminal as my terminal, with vte-0.16.3 as it's renderer. I tried several combinations with xterm, as well, and xterm fails for any prompt I tried with time in it, even the ones that worked with gnome-terminal, so there is some terminal component involved.
Update: I was wrong; the prompts marked "working" don't actually work all the time. They work fine in my homedir, where the path is "~", but as soon as I change directories, they start failing again. So, it's back to 3.1_p17 for me.
I suddenly need a solution to this; sys-apps/portage-2.1.3.15 needs >=app-shells/bash-3.2_p17, and both p17 and p17-r1 are broken. I'd highly prefer not to lose my timestamps in my prompts.
I've found a version of the prompt that works. Basically, you have to set the color before and after the time, or the display is messed up. Here's my working prompt: COLOR1=34 COLOR2=31 PCOLOR1="\[\033[1;${COLOR1}m\]" PCOLOR2="\[\033[1;${COLOR2}m\]" PCOLORN="\[\033[0m\]" PS1="${PCOLOR1}[${PCOLOR1}\A${PCOLOR1}\ ${PCOLOR1} ${PCOLOR1}\h${PCOLOR1}]\ ${PCOLOR2}\W\ ${PCOLORN}>${PCOLORN} "
still a problem with 4.2 ?
No longer a problem with 4.2. This can be closed, as far as I'm concerned.
