how to integrate ripgrep with fzf by using match positions?

[joelpeapen]

I have this function that does live grep.

function rgf() {
    c="rg --column -nS --no-heading --color=always"
    f="$(cmd="$c ''" fzf --bind "change:reload:$c {q} || true" \
         --ansi --layout=reverse --preview '' --header 'Search in files' \
         | cut -d':' -f1 | sed 's/\\/\\\\/g;s/"/\\"/g'
    )"
    if [[ -n $f ]]; then
        $EDITOR $f
        cd $(dirname $(readlink -f "$f"))
    fi
}

Is there a way to get the line number for the selected file so i can $EDITOR $f +$linenumber
to go directly to the line?

This looks like an fzf question or a general shell scripting question. The -n flag tells ripgrep to show line numbers, which you're already using. Otherwise I'm not familiar enough with fzf to easily answer your question.

I also note that you appear to be effectively running rg '', which has got to be just incredibly slow. It also makes clear to me that this isn't a ripgrep question.

okay, thanks for pointing out rg ''. must have been left over from man fzf.

found it. maybe this could be in a tips section.

function rgf() {
    c="rg --column -nS --no-heading --color=always"
    a="$(fzf --bind "change:reload:$c {q} || true" \
        --ansi --reverse --preview '' --header 'Search in files')"
    if [[ -n $a ]]; then
        IFS=':' read -r file line char _ <<< "$a"
        "$EDITOR" "$file" +"$line" -c "norm ${char}lh"
        cd "$(dirname "$(readlink -f "$file")")"
    fi
}

I personally still have no idea what you're trying to do here, so I wouldn't know how to even describe it.

I updated the issue title from a completely genetic thing that meant nothing to me to a more specific guess as to what is being asked here.
