# ripgrep (rg) ⭐⭐⭐⭐⭐
|
||
|
||
## 用途
|
||
极速代码搜索，默认递归搜索且遵守.gitignore
|
||
|
||
## 安装
|
||
|
||
### macOS
|
||
```bash
|
||
brew install ripgrep
|
||
```
|
||
|
||
### Ubuntu/Debian
|
||
```bash
|
||
sudo apt-get install ripgrep
|
||
```
|
||
|
||
## 配置
|
||
```bash
|
||
# 添加到 ~/.bashrc
|
||
alias grep='rg'
|
||
```
|
||
|
||
## 使用
|
||
|
||
```bash
|
||
# 搜索Python文件中的TODO
|
||
rg "TODO" -g "*.py"
|
||
|
||
# 显示上下文（3行）
|
||
rg -A 3 -B 3 "def function_name" app.py
|
||
|
||
# 统计匹配数
|
||
rg --count "import"
|
||
|
||
# 搜索并打开文件
|
||
rg "TODO" --files-with-matches | fzf | xargs bat
|
||
```
|
||
|
||
## 常用选项
|
||
|
||
- `-i` -- 忽略大小写
|
||
- `-g` -- 文件模式匹配（glob）
|
||
- `-A NUM` -- 显示匹配后NUM行
|
||
- `-B NUM` -- 显示匹配前NUM行
|
||
- `-C NUM` -- 显示匹配前后各NUM行
|
||
- `--count` -- 统计匹配数
|
||
- `--files-with-matches` -- 只显示包含匹配的文件名
|
||
|
||
## 技巧
|
||
|
||
```bash
|
||
# 搜索并替换（预览）
|
||
rg "old_function" -S | fzf
|
||
|
||
# 指定编码
|
||
rg --encoding utf8 "pattern"
|
||
|
||
# 与fzf集成
|
||
rg "" --files-with-matches | fzf --preview 'rg --color=always "" {}'
|
||
```
