How to filter history results to items starting with specific string using ^

[risongithub]

I can't search the history results for history items beginning with a specific string.

I think I should be able to press crtl+R then type the caret symbol followed by one or several characters and this should constrain the results to only the history items beginning with those characters - per fzf usage. (https://github.com/junegunn/fzf/blob/master/README.md#search-syntax.)

What happens is that because each line starts with a time string, it is this time string that fzf starts searching in, not in the actual history command lines.

I find this particularly problematic because I have not yet found a way to interactively recall Fish history "lines starting with" from just Fish itself.

If I might suggest simply removing the time at the beginning of each line ? Just personally I have little use for it...

For reference, I hacked __fzf_search_history.fish by removing a line and changing two parameters for my desired result :

function __fzf_search_history --description "Search command history. Replace the command line with the selected command."
    # history merge incorporates history changes from other fish sessions
    builtin history merge
    set command_with_ts (
        # Reference https://devhints.io/strftime to understand strftime format symbols
        #builtin history --null --show-time="%m-%d %H:%M:%S | " |
        builtin history --null |
        fzf --read0 --tiebreak=index --query=(commandline) \
            # preview current command in a window at the bottom 3 lines tall
            --preview="echo {4..}" \
            --preview-window="bottom:3:wrap" |
        string collect
    )

    if test $status -eq 0
        #set command_selected (string split --max 1 " | " $command_with_ts)[2]
        #commandline --replace -- $command_selected
        commandline --replace -- $command_with_ts
    end

    commandline --function repaint
end

Thanks and all the best !

@maciderio Hi! While you may not have use for it, I do and I suspect so do many other people so I'm afraid I won't be removing it. Let me think of another solution, however.

[PatrickF1]

Ok I found a solution. All you need to do is pass in --nth="4.." via FZF_DEFAULT_OPTS and the history string won't be searched. To do this, try following the instructions here https://github.com/PatrickF1/fzf.fish/wiki/FAQ#how-can-i-pass-fzf-options-specific-to-one-command.
In the meantime, when I finally have time, I'm going to implement passing in custom fzf opts to each command to make this process easier.

@maciderio FYI with #140, making this change is even easier through the newly introduced variable $fzf_history_opts.
