Feature request: static prefix for each row that is always visible

[raine]

Hi, thanks for your hard work on fzf.

My use case:

I want to make a UI with fzf where in each entry, there is a timestamp, and very long text on the right side.

cat my_app.log| fzf --nth 2..

But so that, when you type, the timestamp or "prefix" would remain visible always, even the right side is fuzzy matched somewhere.

With the previous command, it behaves like this:

The timestamp becomes hidden, even when just searching the second the second part with--nth 2..

Maybe there could be some flag that makes it so that the non---nth 2.. part is always visible.

Maybe this is already possible. Thank you in advance.

I think option --wrap could be a valid approach to solve your issue.
But I see your log is quite long, so I understand your request.

cat my_app.log | fzf --wrap --nth 2..

The searchable part can be indeed very long. The actual use case is making a claude code conversations searchable

[nenahp]

then u can toggle-wrap when needed

@raine The feature you requested is about to be merged.
Check #4581

Absolute madness. I'm glad the idea was worthy of bringing into fzf 🫡

Thank you.

The timestamp becomes hidden

One workaround is to include the timestamp in the info using --info-command¹. The downside is that one has to shift the focus back to the info, but using some consistent coloring, e.g., 'magenta,' may help a bit.

cat /dev/urandom |
  xxd -c 200 |
  head -10 |
  FZF_DEFAULT_OPTS_FILE='' FZF_DEFAULT_OPTS='' fzf \
    --color 'hl:201:dim,hl+:201:bold' \
    --info-command $'printf "%b%s%b %s" "\e[35;1m" {1} "\e[m" $FZF_INFO' \
    --multi \
    --nth 2.. \
    --query abc

This is currently not possible. While I'm open to the idea, implementing this is not going to be trivial, so I can't make any promises.

In these cases, I usually reformat each line into a multi-line entry, so that the timestamp (and some other metadata) is always visible on a separate line.

cat my_app.log | perl -pe 's/\n/\0/s; s/ /\n ⋅ /' | fzf --read0 --gap
