Combinaten zsh + promptline + urxvt won't work well

[ljrk0]

Any other combination combination works:
zsh + promptline + qterminal
bash + promptline + urxvt
zsh + not promptline + urxvt

The first line suggests urxvt is the problem, the second, zsh and the third that promptline is the problem.

The problem itself / steps to reproduce:

• set up urxvt with zsh and promptline (obviously)
• type something
• result:
  MYPROMPT>WHATITYPED
• hit Ctrl-C and type something
• result:
  MYPROMPT> WHATITYPEDNOW

notice the whitespace between the > and what I typed in the latter example?
This wouldn't be a major issue itself but when being in the state of having no whitespace one can get wired behavior for example like this:

• be in "missing whitespace" mode
• type cd and the beginning of a folder name but only so far as it is still ambiguos.
• hit tab to get auto-completion
• the result will be:
  MYPROMPT>ccd ...

now there's a 'ccd'.
These are only "easily reproducible" examples but it can get really weird when one is using the terminal for a longer time.

Probably related to #26 – but I don't know why it's only in urxvt

Probably this commit should fix it:
mhartington/dotfiles@44f81a3
but removing those two lines (the L37 I do not have but I just removed all oh-my-zsh lines) but it won't work for me.

I'm seeing this same issue using Konsole and Termite

Invoking C-c seems to mitigate this, so the prompt is using some function urxvt doesn't like.

EDIT: Seems it's something in

function __promptline_last_exit_code {
    [[ $last_exit_code -gt 0 ]] || return 1;

   printf "%s" "$last_exit_code"
} 

Commenting out the if statement fixes the indent issue, but the return code is always displayed. Also confirmed this, false fixes the issue too.

EDIT 2: Done some more digging, turns out RPROMPT is the issue.

EDIT 3: I seem to have fixed it. I'm looking into creating a PR, but for now make __promptline_right_prompt similar to below.

function __promptline_right_prompt {
     local slice_prefix slice_empty_prefix slice_joiner slice_suffix

     if [ ! -e $(__promptline_last_exit_code) ]; then
     # section "warn" header
     slice_prefix="${warn_sep_fg}${rsep}${warn_fg}${warn_bg}${space}" slice_suffix="$space${warn_sep_fg}"                                                   
    slice_joiner="${warn_fg}${warn_bg}${alt_rsep}${space}" slice_empty_prefix=""
     # section "warn" slices
       __promptline_wrapper "$(__promptline_last_exit_code)" "$slice_prefix" "$slice_suffix" && { slice_prefix="$slice_joiner"; }
     else
       slice_prefix="${reset}"
      __promptline_wrapper "${reset} "
    fi

Result is various terminals.

Still an issue in bash under WSL
