Fuzzy File System Search

This script will use riggrep along with fzf to unleash awesome filesystem search capabilities. It will open the file in intellij.

ADDR=(${@//--/ })

RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case ${ADDR[1]}"
INITIAL_QUERY="${ADDR[0]:-}"

IFS=: read -ra selected < <(
  FZF_DEFAULT_COMMAND="$RG_PREFIX $(printf %q "$INITIAL_QUERY")" \
  fzf --ansi \
      --color "hl:-1:underline,hl+:-1:underline:reverse" \
      --disabled --query "$INITIAL_QUERY" \
      --bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true" \
      --bind "alt-enter:unbind(change,alt-enter)+change-prompt(2. fzf> )+enable-search+clear-query" \
      --prompt '1. ripgrep> ' \
      --delimiter : \
      --preview 'bat --color=always {1} --highlight-line {2}' \
      --preview-window 'up,60%,border-bottom,+{2}+3/3,~3'
)
[ -n "${selected[0]}" ] && idea --line "${selected[1]}" "${selected[0]}"

Emacs variant, you can use vim as well.
