Padding on the right prompt

[MycroftHolmes1989]

I am using the my powerlevel9k config with powerlevel10k on Ubuntu. On Terminator as well as GNOME Terminal Emulator, there is some padding on right side of the right prompt. The issue is demonstrated on this screenshot. My config for the right prompt is:
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status command_execution_time background_jobs history)

Try the following experiment. Type this command:

PROMPT='X> ' RPROMPT='<X' zsh -df

Note that there is space after <X on the right. Now type this:

ZLE_RPROMPT_INDENT=0

The space is gone. You can also try ZLE_RPROMPT_INDENT=2.

From http://zsh.sourceforge.net/Doc/Release/Parameters.html:

ZLE_RPROMPT_INDENT <S>

If set, used to give the indentation between the right hand side of the right prompt in the line editor as given by RPS1 or RPROMPT and the right hand side of the screen. If not set, the value 1 is used.

What you see with p10k is the expected behavior. p9k has a bug: Powerlevel9k/powerlevel9k#1292.

If you don't want to have right prompt indented, set ZLE_RPROMPT_INDENT=0. Note that it may trigger a bug in ZSH on some terminals. This bug will cause the cursor to be positioned incorrectly. I've fixed the bug in zsh-users/zsh@3eea35d but there hasn't been a ZSH release since then. If you really want to get rid of the space and you must use a terminal on which the bug triggers, you'll need to build ZSH yourself.

[MycroftHolmes1989]

Thank you for the explanation. Setting ZLE_RPROMPT_INDENT=0 does solve it, and Terminator does not seem to trigger the bug.

[romkatv]

Terminator does not seem to trigger the bug.

I hope this is true although this doesn't match my recollection.

To ensure the bug is indeed not triggered you can conduct these tests.

1. When you prompt is empty, verify that the cursor is where it's supposed to be. If there is no space between the end of left prompt and the cursor, you are affected by the bug.
2. Press ctrl+r. The cursor must not move. If it does move to the right, you are affected by the bug.
3. Type ls<tab>. You should have ls on the screen with the cursor positioned right after it. If the cursor is positioned on s, you are affected by the bug.

[MycroftHolmes1989]

Okay. I stand corrected. Both Terminator and GNOME Terminal are affected by it.

[romkatv]

@MycroftHolmes1989 I've implemented a workaround in Powerlevel10k for the ZSH bug.

If you update powerlevel10k, your cursor should behave correctly even if you set ZLE_RPROMPT_INDENT=0. Please let me know whether it works for you.

[MycroftHolmes1989]

Unfortunately, it doesn't work on Terminator or GNOME Terminal, even after the update.

[romkatv]

This is surprising, as I've tested my workaround on these terminals. Please type zsh -df and then paste the following:

rm -rf /tmp/p10k
git clone https://github.com/romkatv/powerlevel10k.git /tmp/p10k
ZLE_RPROMPT_INDENT=0
source /tmp/p10k/powerlevel10k.zsh-theme

If this works, the most likely explanation is that your powerlevel10k version is not up to date.

[MycroftHolmes1989]

It works when I do it from /tmp. But I have deleted $ZSH_CUSTOM/themes/powerlevel10k, and then installed it again, but it's still not working on GNOME Terminal or Terminator.

[romkatv]

Please post a screenshot of your prompt (when it's in the non-working state) and your ~/.zshrc.

You need to put ZLE_RPROMPT_INDENT=0 in your ~/.zshrc. This will enable the special workaround I implemented in p10k. When you are typing ZLE_RPROMPT_INDENT=0 in your terminal, you are getting the native ZSH experience, which has a bug in your version of ZSH.

[MycroftHolmes1989]

Resolved! Thanks.

[romkatv]

Phew! That was a tough one. Thanks for verifying.

[enkeyz]

Every time I do a fresh install of a linux distro and install powerlevel10k, this "bug" is always comes up. I'm here for the 20th time :P

[romkatv]

@enkeyz It's a good idea to keep your .zshrc and other rc files in a git repository from which you can recover them when reinstalling the OS.
