Trouble getting the reload with transform correctly

[rbhanot4739]

Hello,

I am not sure if this is a bug or just something wrong with the way I am doing things, so apologies in advance for that. Please consider the below query

❯ ls -l |grep py | fzf --prompt 'Files> ' --bind '?:transform:[[ ! $FZF_PROMPT =~ Files ]] && echo "change-prompt(Files> )+reload(ls -l | grep py)" || echo "change-prompt(Zoxide> )+reload(zoxide query -l | head -n 10 | xargs -I {} basename {})"'

and here is how it behaves: as I could observe this happens due to the exit status of the ls -l |grep py being non-zero since no match was found but why would that interfere with the second reload query ?

rec1.mp4

And here is how it behaves when I reverse the grep pattern

ls -l |grep -v py | fzf --prompt 'Files> ' --bind '?:transform:[[ ! $FZF_PROMPT =~ Files ]] && echo "change-prompt(Files> )+reload(ls -l | grep -v py)" || echo "change-prompt(Zoxide> )+reload(zoxide query -l | head -n 10 | xargs -I {} basename {})"'

rec2.mp4

So I am not sure how do I handle this or what is the right way of doing this.

A common mistake when writing a lengthy transform script is not escaping the placeholders, making them evaluated right away.

Can you try escaping {} to \{} in your script?

I tried with escaping the {} as well but it didn't work.. infact escaping \{} makes the second reload zoxide does not evaluate at all.

 ls -l |grep py | fzf --prompt 'Files> ' --bind '?:transform:[[ ! $FZF_PROMPT =~ Files ]] && echo "change-prompt(Files> )+reload(ls -l | grep py)" || echo "change-prompt(Zoxide> )+reload(zoxide query -l | head -n 10 | xargs -I \{} basename \{})"'

WIth above when I press ? the zoxide query does not get executed.

I think you shouldn't be using {} as a placeholder expression for xargs, as it makes things really hard to comprehend. Try something like xargs -I {x} basename {x} not to make fzf's evaluation happen at all at any stage.

@junegunn Thank you helping patiently, {x} indeed did the trick.
