Find in file using ripgrep, then fuzzy find matched filenames with fzf, preview match using bat

fif.sh

fif() {
	rg  \
	--column \
	--line-number \
	--no-column \
	--no-heading \
	--fixed-strings \
	--ignore-case \
	--hidden \
	--follow \
	--glob '!.git/*' "$1" \
	| awk -F  ":" '/1/ {start = $2<5 ? 0 : $2 - 5; end = $2 + 5; print $1 " " $2 " " start ":" end}' \
	| fzf --preview 'bat --wrap character --color always {1} --highlight-line {2} --line-range {3}' --preview-window wrap
}

updated to work in zsh

Here's the same solution, but also open in your favorite editor in the exact line number.

fif() {
        out=$(rg \
	--column \
	--line-number \
	--no-column \
	--no-heading \
	--fixed-strings \
	--ignore-case \
	--hidden \
	--follow \
	--glob '!.git/*' "$1" \
	| awk -F  ":" '/1/ {start = $2<5 ? 0 : $2 - 5; end = $2 + 5; print $1 " " $2 " " start ":" end}' \
	| fzf --preview 'bat --wrap character --color always {1} --highlight-line {2} --line-range {3}' --preview-window wrap)
        
        read -r filename line <<< "${out}"
        ${EDITOR:-vim} "${filename}" +"normal! ${line}zz"
}

Slight variant that leverages a key binding (ctrl+o) for opening the file in vscode at the proper line and column while selected in fzf

fif() {
    rg  \
    --column \
    --no-heading \
    --fixed-strings \
    --ignore-case \
    --hidden \
    --follow \
    --glob '!.git/*' \
    --glob '!.vscode-server/*' \
     "$1" \
    | awk -F  ":" '/1/ {start = $2<5 ? 0 : $2 - 5; end = $2 + 5; print $1 " " $2 " " $3 " " start ":" end}' \
    | fzf \
        --bind 'ctrl-o:execute(code --goto {1}:{2}:{3})+cancel' \
        --preview 'bat --wrap character --color always {1} --highlight-line {2} --line-range {4}' \
        --preview-window wrap
}

The output from awk expression is in the form of:

<filename> <linenum> <col> <linenum-5>:<linenum+5>

fzf lets you access the different space separated fields from its input using the {num} syntax

The syntax for opening a file at specified line and column in vscode is code --goto <filename>:<line>:<column>
