tmux: creating new windows or (split window) panes.

[ravensorrow]

I noticed over the last 2 days, while I was refining my .zshrc, that when I created new tmux windows or panes w/i tmux, that pl10k pukes all over my console with the following message,

[WARNING]: Console output during zsh initialization detected.

When using Powerlevel10k with instant prompt, console output during zsh
initialization may indicate issues.

You can:

  - Recommended: Change ~/.zshrc so that it does not perform console I/O
    after the instant prompt preamble. See the link below for details.

    * You will not see this error message again.
    * Zsh will start quickly and prompt will update smoothly.

  - Suppress this warning either by running p10k configure or by manually
    defining the following parameter:

      typeset -g POWERLEVEL9K_INSTANT_PROMPT=quiet

    * You will not see this error message again.
    * Zsh will start quickly but prompt will jump down after initialization.

  - Disable instant prompt either by running p10k configure or by manually
    defining the following parameter:

      typeset -g POWERLEVEL9K_INSTANT_PROMPT=off

    * You will not see this error message again.
    * Zsh will start slowly.

  - Do nothing.

    * You will see this error message every time you start zsh.
    * Zsh will start quickly but prompt will jump down after initialization.

-- console output produced during zsh initialization follows --

If I open a new terminal window from my terminal client, that error message doesn't appear, and it doesn't appear the first time tmux is called to replace the already running shell. Is there something special that has to be done w/ either zsh or powerlevel10k that I am not aware of?

My .zshrc for context is as follows.

# Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
# Initialization code that may require console input (password prompts, [y/n]
# confirmations, etc.) must go above this block; everything else may go below.

When you see that warning, what is the output of typeset -p P9K_STARTUP_CONSOLE_OUTPUT?

[ravensorrow]

OK, so I figured this out with your response. It was a combination of keychain and VFD (a local script of fortune from a specific file and then pipped to cowsay). I moved them to the top, and the problem appears to have resolved itself.

This would be a good diagnostic tool to list in the above error message to help diagnose a problem like this.

[romkatv]

Wasn't there anything below the "-- console output produced during zsh initialization follows --"? I just assumed you cut out the important part when filing the issue.

[ravensorrow]

No, it was just my prompt at that point. I figured my themed prompt wasn't necessary for the issue lol.

[romkatv]

When you see that warning, what is the output of typeset -p P9K_STARTUP_CONSOLE_OUTPUT?

What is the answer to this question then?

[ravensorrow]

'Keychain' and 'fortune' produced output at console initialization, which was producing the output interfering with the pl10k instant prompt, and moving these to before pl10k's instant prompt initialization resolved the problem.

[romkatv]

When you see that warning, what is the output of typeset -p P9K_STARTUP_CONSOLE_OUTPUT?

This would be a good diagnostic tool to list in the above error message to help diagnose a problem like this.

I'm trying to address this suggestion of yours. It would be a lot easier if you could answer my question.

[ravensorrow]

I apologize; I misunderstood. The suggestion being 'typeset -p P9K_STARTUP_CONSOLE_OUTPUT' would be good to have printed in the pl10k instant prompt error message. This immediately allowed me to correct my issues and I thought this would be useful for others to self-diagnose.

[romkatv]

No need to apologize.

I give up though.
