Keybindings stop working if the transient prompt is enabled in zsh

What happened?

I'm sure that Home and End work correctly before the transient prompt is enabled in zsh. However, once it is enabled, the two keybindings stop working. Tested without other plugins. If I run zle -N zle-line-init, which disables the transient prompt, the keybindings will work again.

Theme

(This happens with any theme configs, basically irrelevant.)

What OS are you seeing the problem on?

Linux

Which shell are you using?

zsh

Log output

@lewis-yeung not something specific to oh-my-posh it seems. Can you have a look at this issue?

[lewis-yeung]

@JanDeDobbeleer Thank you for mentioning that issue. I'm sure that _posh-zle-line-init function has something to do with it, however I don't know how to fix it. Anyway, I can just make the two keys work on my end by binding them via:

bindkey "^[[F" end-of-line
bindkey "^[[H" beginning-of-line

[JanDeDobbeleer]

@lewis-yeung did some research, can you validate the changes in #2595? I have no end/home keys...

[lewis-yeung]

@JanDeDobbeleer I have tried your quick fix but the problem persists...

I believe this is related to the application mode vs normal mode (keybinds values of arrows change between these two mode for example "^[[A" vs "^[OA" ) while I didn't figure out how to properly fix.

[StanSvec]

It happens in my case too. This discussion may be related. I'm fixing it by adding these lines in .zshrc after oh-my-posh init:

bindkey '^[[A' up-line-or-search
bindkey '^[[B' down-line-or-search

[JanDeDobbeleer]

I wonder if we should add this after we enable transient prompt.

[StanSvec]

Unfortunately my knowledge of shells/unix is insufficient to provide any advice. But it sounds like a good idea. To correct myself to restore the exact previous behavior of up/down arrow keys this needs to be added in my case:

bindkey '^[[A' up-line-or-beginning-search
bindkey '^[[B' down-line-or-beginning-search

The solution from version 12.4.0 (b174c27) was good. Home/End keys worked. However, in version 12.5.1 (a94ce52) they do not work again.
Zsh version: 5.8.1 (x86_64-apple-darwin21.0)

[lewis-yeung]

@JanDeDobbeleer Should we add these back?

bindkey '^[[F' end-of-line
bindkey '^[[H' beginning-of-line

[refactorized]

don't know what this is all about, but I tried oh-my-posh today and it broke zsh, because every time I press up or down arrow (the actual arrow keys on an abbple macbook, running xterm-256color emulation) I get:

No such widget `up-line-or-beginning-search'

[JanDeDobbeleer]

@refactorized is your zsh version up-to-date?

[refactorized]

I thought it was reasonably up to date, 5.8.1 i think, but I just updated to zsh 5.9 (x86_64-apple-darwin21.3.0) and seem to be having the same issue. Do I need to run any kind of completion scripts? I do some compinit stuff later on in the rc, i don't know if that affects anything, but I only have problems if I eval the oh-my-posh init zsh stuff.

[JanDeDobbeleer]

@refactorized check #2999

[michalzielanski]

@JanDeDobbeleer The fix for someone is a regression for others. After the changes from e884a6a, fuzzy find history (Start typing + [Up/Down-Arrow]) does not work for me.
Maybe restoring keybindings should be done conditionally? Maybe like this:

if [[ $(zle -la | grep ^up-line-or-beginning-search$) ]]; then
  bindkey '^[[A' up-line-or-beginning-search
  bindkey '^[[B' down-line-or-beginning-search
fi
