[FR] Map TAB to "accept" when there is only one item

[jmgq]

This feature is better described with an example:

Let's say that if you go to your home folder and type less .zsh and then press TAB, you will be presented with a list with three options:

• .zshrc
• .zshenv
• .zsh_hist

Every time you press TAB, it will highlight the next item, as you would expect. However, if you type the letter r, the list of suggestions will be filtered, and the only available option will be .zshrc.

In this case, when there is just one option available, I think that if you press TAB again, it would be good if .zshrc was automatically selected, since it's the only available option. But instead, nothing happens until you press ENTER, in which case the option is selected.

After checking the fzf manual, I noticed that there is a flag called --select-1 under the "Scripting" section, and its description reads "Automatically select the only match". I have tried the following configurations, with no success:

zstyle ':fzf-tab:*' fzf-flags --select-1
zstyle ':fzf-tab:*' extra-opts '--select-1'
export FZF_DEFAULT_OPTS="--select-1"

I have also tried zstyle ':fzf-tab:*' fzf-bindings 'tab:accept', but that of course removes the cycling with TAB feature (you'll have to use the arrow keys to navigate through the options).

--select-1 only works on the initial input, like echo a | fzf --select-1.

I think there is no way to implement it.

Fair enough, thanks for looking into it anyway. I wish I could help or suggest something, but I wouldn't know where to start, so please feel free to close this issue if it looks like it cannot be done.

fzf has the event one. So this could be possible.
