fzf 筛选 + 搜索

vim or code 打开文件

  1. #!/usr/bin/env bash
  3. # 1. Search for text in files using Ripgrep
  4. # 2. Interactively narrow down the list using fzf
  5. # 3. Open the file in Vim
  6. export FZF_DEFAULT_COMMAND='fdfind --type f'
  8. function __bat_line_range() {
  9.     local line_range=10
  10.     local start_line=`expr $1 - $line_range`
  11.     [ $start_line -le 1 ] && start_line=1
  12.     echo $start_line:`expr $1 + $line_range`
  13. }
  15. export -f __bat_line_range
  18. if [ $# -ge 1 ]; then
  19.     # 使用 rg 搜索过滤一下
  20.     IFS=: read -ra selected < <(
  21.         rg --color=always --line-number --no-heading --smart-case "$@" |
  22.             fzf --ansi \
  23.                 --delimiter : \
  24.                 --preview 'bat {1} --highlight-line {2} --line-range `__bat_line_range {2}`' \
  25.         )    
  26. else
  27.     # 没有参数， 直接fzf 过滤
  28.     IFS=: read -ra selected < <(fzf --preview "bat --style=numbers --color=always --line-range :20 {}")
  29. fi
  31. function __fzf_openfile() {
  32.     echo `realpath $1`
  33.     if code -v > /dev/null 2>&1; then
  34.         code --goto "$1":"$2"
  35.     else
  36.         vim "$1" +"$2"
  37.     fi
  38.     echo 
  39. }
  41. [ -n "${selected[0]}" ] && __fzf_openfile "${selected[0]}" "${selected[1]}"

设置默认配置

  1. zcz@zcz-pc:~/work$ ranger --copy-config=all
  2. creating: /home/zcz/.config/ranger/rifle.conf
  3. creating: /home/zcz/.config/ranger/commands.py
  4. creating: /home/zcz/.config/ranger/commands_full.py
  5. creating: /home/zcz/.config/ranger/rc.conf
  6. creating: /home/zcz/.config/ranger/scope.sh

绑定fzf

/home/zcz/.config/ranger/commands.py
fzf_select 关键词

Q键退出

https://github.com/ranger/ranger/wiki/Integration-with-other-programs#changing-directories
下面的函数放到启动脚本中

  1. #!/bin/bash
  3. function r {
  4.     export EDITOR=vim
  5.     if code -v > /dev/null 2>&1; then
  6.         export EDITOR=code
  7.     fi
  8.     local IFS=$'\t\n'
  9.     local tempfile="$(mktemp -t tmp.XXXXXX)"
  10.     local ranger_cmd=(
  11.         command
  12.         ranger
  13.         --cmd="map Q chain shell echo %d > "$tempfile"; quitall"
  14.     )
  16.     ${ranger_cmd[@]} "$@"
  17.     if [[ -f "$tempfile" ]] && [[ "$(cat -- "$tempfile")" != "$(echo -n `pwd`)" ]]; then
  18.         cd -- "$(cat "$tempfile")" || return
  19.     fi
  20.     command rm -f -- "$tempfile" 2>/dev/null
  21. }

ranger 修改编辑器

code 是vscde 的命令行， 不建议直接在 启动脚本中使用， 可以在 启动脚本中包装一个 函数。 在函数中使用这个命令。 

  1. export EDITOR=vim
  2. if code -v > /dev/null 2>&1; then
  3.     export EDITOR=code
  4. fi
