VMware WorkStation 14 pro安装Ubuntu 17.04教程

前言

说到文本搜索工具，大家一定会知道 grep, 它是 linux 最有用并最常用的工具之一。

但如果要再一个大的工程项目中搜索某个关键词，大家也一定知道它比较耗时。

所以就有了很多替代工具，之前最出名的是 Ack，Ag

而最近又有了新的替代者 Ripgrep, 这个工具和 Ack/Ag 一样都使用了多线程的方法，但 rg 比它们更快

简介

ripgrep 是一个以行为单位的搜索工具， 它根据提供的 pattern 递归地在指定的目录里搜索。它是由 Rust 语言写成，相较与同类工具，它的特点就是无与伦比地快。

几个特点如下：

• 自动递归搜索 （grep 需要-R）
• 自动忽略.gitignore 中的文件以及 2 进制文件
• 可以搜索指定文件类型（rg -tpy foo限定 python 文件， rg -Tjs foo排除 js 文件)
• 支持大部分 grep 的 feature(常用的都有)
• 支持各种文件编译（UTF-8， UTF-16， latin-1, GBK, EUC-JP, Shift_JIS 等等）
• 支持搜索常见压缩文件(gzip, xz, lzma, bzip2, lz4)
• 自动高亮匹配的结果
• 更少的命令名称 rg (grep 是四个字符)
• 不支持多行搜索和花哨的正则

安装 ripgrep

先安装 RUST

curl https://sh.rustup.rs -sSf | sh

然后一路 enter 就好了

用 RUST 安装 rigpre

git clone https://github.com/BurntSushi/ripgrep
cd ripgrep
cargo build --release
cp ./target/release/rg /usr/local/bin/

最后一步根据你的情况把它放到某个在 PATH 里的路径里

使用

用法总体格式

USAGE:
  rg [OPTIONS] PATTERN [PATH ...]
  rg [OPTIONS] [-e PATTERN ...] [-f PATTERNFILE ...] [PATH ...]
  rg [OPTIONS] --files [PATH ...]
  rg [OPTIONS] --type-list
  command | rg [OPTIONS] PATTERN

输入参数

ARGS:
  <PATTERN>
      A regular expression used for searching. To match a pattern beginning with a
      dash, use the -e/--regexp flag.

      For example, to search for the literal '-foo', you can use this flag:

        rg -e -foo

      You can also use the special '--' delimiter to indicate that no more flags
      will be provided. Namely, the following is equivalent to the above:

        rg -- -foo

  <PATH>...
      A file or directory to search. Directories are searched recursively. Paths specified on
      the command line override glob and ignore rules.

实例展示

实例一

$ rg 'name' ./

实例二

搜索name为独立单词的内容(-w), 相当于<pattern>

$ rg -w 'name' ./

实例三

只打印包含匹配内容的文件名(-l)

$ rg -w 'name' ./ -l
src/cpp/epoll_server.cpp
src/cpp/uart_xtor.cpp

实例四

只搜索cpp文件(-t), 可以用-T来不搜索某种类型文件

$ rg -w 'name' ./ -tcpp

实例五

正则搜索(-e)

$ rg -e "sa.*port" ./ -tcpp

实例六

显示匹配内容及上下各两行(-C), -A/-B类似

$ rg -e "sa.*port" ./ -tcpp -C2

实例七

显示不含"debug"的行(-v)

$ rg -v "debug" -tcpp ./

实例八

只显示匹配部分(-o)

$ rg -e "if.*debug" ./ -tcpp -o

实例九

忽略大小写(-i)

$ rg -ie "if.*debug" ./ -tcpp -o

实例十

把pattern当成常量字符(-F), 像.(){}*+不需要escape，如果要搜索的字符是以-开头，那么要用--来作为分隔符，或者用rg -e "-foo"

rg -F "i++)" ./ -tcpp

实例十一

打印所有将被搜索的文件 --files

rg --files

实例十二

输出内置识别文件类型

总结

ripgrep的搜索速度真是快的飞起来，在浏览代码时对我的帮助非常大。我相信它对于每一个码农的价值都是无限大的，特别是结合FZF之后。

唯一的弱点是对正则的支持，但这是一个取舍，如果采用如PCRE那样的库的话，一定会极大影响速度。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持我们。
