Mac下的shell配置

zsh设置为默认shell

查看当前已安装shells：

cat /etc/shells

更改mac默认shell为zsh:

chsh -s /usr/local/bin/zsh

更改zsh配置文件：

vim ~/.zshrc

更改完配置记得运行：

source ~/.zshrc

还原默认shell：

chsh -s /bin/bash

Zsh不支持通配符(* )匹配和正则表达式解决方法

在~/.zshrc中添加以下内容:

# ignore no matches
set -o nonomatch
#setopt nonomatch

安装oh-my-zsh

  • via curl 
    sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
  • via wget 
    sh -c "$(wget https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)"

运行上述命令以后~/.zshrc会自动配置为:

# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH

# Path to your oh-my-zsh installation.
export ZSH=$HOME/.oh-my-zsh

# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
ZSH_THEME="robbyrussell"

# Set list of themes to pick from when loading at random
# Setting this variable when ZSH_THEME=random will cause zsh to load
# a theme from this variable instead of looking in ~/.oh-my-zsh/themes/
# If set to an empty array, this variable will have no effect.
# ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )

# Uncomment the following line to use case-sensitive completion.
# CASE_SENSITIVE="true"

# Uncomment the following line to use hyphen-insensitive completion.
# Case-sensitive completion must be off. _ and - will be interchangeable.

# Uncomment the following line to disable bi-weekly auto-update checks.
# DISABLE_AUTO_UPDATE="true"

# Uncomment the following line to change how often to auto-update (in days).
# export UPDATE_ZSH_DAYS=13

# Uncomment the following line to disable colors in ls.
# DISABLE_LS_COLORS="true"

# Uncomment the following line to disable auto-setting terminal title.
# DISABLE_AUTO_TITLE="true"

# Uncomment the following line to enable command auto-correction.
# ENABLE_CORRECTION="true"

# Uncomment the following line to display red dots whilst waiting for completion.
# COMPLETION_WAITING_DOTS="true"

# Uncomment the following line if you want to disable marking untracked files
# under VCS as dirty. This makes repository status check for large repositories
# much, much faster.
# DISABLE_UNTRACKED_FILES_DIRTY="true"

# Uncomment the following line if you want to change the command execution time
# stamp shown in the history command output.
# You can set one of the optional three formats:
# "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd"
# or set a custom format using the strftime function format specifications,
# see 'man strftime' for details.
# HIST_STAMPS="mm/dd/yyyy"

# Would you like to use another custom folder than $ZSH/custom?
# ZSH_CUSTOM=/path/to/new-custom-folder

# Which plugins would you like to load?
# Standard plugins can be found in ~/.oh-my-zsh/plugins/*
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
plugins=(git)

  • Oh My Zsh

    1. Clone this repository into $ZSH_CUSTOM/plugins (by default ~/.oh-my-zsh/custom/plugins): 
      git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
    2. Add the plugin to the list of plugins for Oh My Zsh to load (inside ~/.zshrc): 
      plugins=(
            git
            zsh-autosuggestions
        )
    3. Start a new terminal session.

  • Manual (Git Clone)

    1. Clone this repository somewhere on your machine. This guide will assume ~/.zsh/zsh-autosuggestions: 
      git clone https://github.com/zsh-users/zsh-autosuggestions ~/.zsh/zsh-autosuggestions
    2. Add the following to your .zshrc: 
      source ~/.zsh/zsh-autosuggestions/zsh-autosuggestions.zsh

安装zsh-syntax-highlighting

已知命令语法高亮 GitHub地址:https://github.com/zsh-users/zsh-syntax-highlighting

安装后效果如下: Before: png After: png

Before: png After: png

Before: png After: png

安装方法:

  • 安装到Oh-my-zsh

    1. Clone this repository in oh-my-zsh's plugins directory:
    git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
    1. Activate the plugin in ~/.zshrc:
    plugins=(
          git
          zsh-autosuggestions
          zsh-syntax-highlighting
        )
    1. Source ~/.zshrc to take changes into account:
    source ~/.zshrc

  • 安装到~/.zshrc

    1. Simply clone this repository and source the script:
    git clone https://github.com/zsh-users/zsh-syntax-highlighting.git
echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ${ZDOTDIR:-$HOME}/.zshrc
    1. Then, enable syntax highlighting in the current interactive shell:
    source ./zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

    If git is not installed, download and extract a snapshot of the latest development tree from:

    https://github.com/zsh-users/zsh-syntax-highlighting/archive/master.tar.gz

    Note the source command must be at the end of ~/.zshrc:

    source ~/.zshrc

安装scm_breeze

git clone git://github.com/scmbreeze/scm_breeze.git ~/.scm_breeze
~/.scm_breeze/install.sh
source ~/.bashrc   # or source "${ZDOTDIR:-$HOME}/.zshrc"

The install script creates required default configs and adds the following line to your .bashrc or .zshrc:

[ -s "$HOME/.scm_breeze/scm_breeze.sh" ] && source "$HOME/.scm_breeze/scm_breeze.sh"

Note: You need to install ruby for some SCM Breeze commands to work. This also improves performance. See ruby-lang.org for installation information. Mac上安装有执行ll会遇到以下问题：
scm_breeze_error
解决方法是：
This has nothing to do with bash. Command ls is not a builtin of bash.

macOS is based on the Unix operating system. Some of its basic commands are BSD flavored. The --group-directories-first option you want is available in GNU ls only. All you need is a GNU flavored ls.

Solution: install coreutils, in which GNU ls is included.

brew install coreutils

Add the following code into ~/.zshrc or ~/.bash_profile , to prioritize the ls command and other GNU flavored commands over the builtin BSD flavored command in macOS.

# Make all GNU flavor commands available, may override same-name BSD flavor commands
# For x86 Mac
export PATH="/usr/local/opt/coreutils/libexec/gnubin:${PATH}"
export MANPATH="/usr/local/opt/coreutils/libexec/gnuman:${MANPATH}"

# For M1 Mac
export PATH="/opt/homebrew/opt/coreutils/libexec/gnubin:${PATH}"
export MANPATH="/opt/homebrew/opt/coreutils/libexec/gnuman:${MANPATH}"

If you only want the GNU ls but not other GNU flavored commands. Don't add the above content, but create an alias in ~/.zshrc or ~/.bash_profile.

# For x86 Mac
alias ls="/usr/local/opt/coreutils/libexec/gnubin/ls"

# For M1 Mac
alias ls="/opt/homebrew/opt/coreutils/libexec/gnubin/ls"

Here's all commands brought by coreutils.

❯ ls /usr/local/opt/coreutils/libexec/gnubin
'['	    chmod    dd		 expr	  install   mkfifo   od         readlink    sha384sum   stty	  tr	     uptime

安装colorls

项目GitHub地址: https://github.com/athityakumar/colorls

先上效果图: png

安装

  1. Mac检查Ruby版本 (preferably, version > 2.1) 默认情况下，Mac OS X系统已经安装好 Ruby，在命令行下可以直接通过以下命令，确认系统Ruby的版本信息:

    ruby --version

    若系统自带的Ruby版本不符合>2.1上述要求，推荐使用homebrew来安装、管理Ruby的版本:

    brew update
brew install ruby
echo '# Ruby installed by Homebrew' >> ~/.zshrc
echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

    ruby ruby ruby png

  2. 安装字体并设置iTerm2的显示字体，否则icon显示不全， 推荐powerline nerd-font。 可以查看 Nerd Font README 来获得更多安装详细介绍。

    Note for iTerm2 users - Please enable the Nerd Font at iTerm2 > Preferences > Profiles > Text > Non-ASCII font > mononoki Nerd Font. iTerm2

  3. Install the colorls ruby gem with：

    gem install colorls

    colorls

  4. Enable tab completion for flags by entering following line to your shell configuration file (~/.bashrc or ~/.zshrc) :

    source $(dirname $(gem which colorls))/tab_complete.sh

配置colorls环境

配置Bash或Zsh环境，这里以Zsh配置为例: 进入~/.zshrc配置文件:

vim ~/.zshrc

在文件末追加以下内容:

# Colorls
PATH=$PATH:$(ruby -e 'puts Gem.bindir')

在命令行可以使用colorls来代替ls，也可以通过下面配置ls别名来替代colorls:

alias ls='colorls'
alias ll='colorls -lA --report'
alias lc='colorls -lA --sd'

使其生效:

source ~/.zshrc

安装过程中遇到的问题

在安装的过程中遇到Zsh不识别colorls命令: colorls-error 但是运行/usr/local/lib/ruby/gems/2.6.0/gems/colorls-1.1.1/exe/colorls是可以的： colorls2 临时的解决方法是(上面的colorls配置已经彻底解决该问题，以下为当时的心路历程,😂):

#cp /usr/local/lib/ruby/gems/2.6.0/gems/colorls-1.1.1/exe/colorls /usr/local/opt/ruby/bin/
cp /usr/local/lib/ruby/gems/2.6.0/bin/colorls /usr/local/opt/ruby/bin/

colorls-error1 经过跟作者的沟通原来是没有将Gem.bindir加入环境变量中， 上面colorls配置中已经添加，彻底解决了该问题：

echo 'export ATH=$PATH:$(ruby -e 'puts Gem.bindir')"' >> ~/.zshrc

以下为作者的回答

@aimuch as I already said, you need to ensure your shell is able to find the colorls script. You should add the Gem.bindir directory to your PATH environment variable in order to run scripts from any installed gem. Look at the output of gem environment. The directory mentioned in EXECUTABLE DIRECTORY should be also listed in SHELL PATH. Add this to your shell init file: PATH=$PATH:$(ruby -e 'puts Gem.bindir')

升级colorls

gem update colorls

卸载colorls

gem uninstall colorls

VIMRC自动配置VIM

git clone --depth=1 https://github.com/amix/vimrc.git ~/.vim_runtime

sh ~/.vim_runtime/install_awesome_vimrc.sh

安装后~/.vimrc会自动配置为：

 set runtimepath+=~/.vim_runtime

 source ~/.vim_runtime/vimrcs/basic.vim
 source ~/.vim_runtime/vimrcs/filetypes.vim
 source ~/.vim_runtime/vimrcs/plugins_config.vim
 source ~/.vim_runtime/vimrcs/extended.vim

 try
 source ~/.vim_runtime/my_configs.vim
 catch
 endtry

升级vimrc:

cd ~/.vim_runtime
git pull --rebase

安装Vundle管理插件

官方GitHub地址: https://github.com/VundleVim/Vundle.vim

快速开始

  • 介绍: 安装需要Git,触发git clone,默认将每一个指定特定格式插件的仓库复制到~/.vim/bundle/. 搜索需要Curl支持.

  • 初始安装 Vundle:

git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
  • 配置插件 : 请将以下加在 .vimrc 方可使用Vundle. 删掉你不需要的插件, 这些只是用做示例:
set nocompatible              " 去除VI一致性,必须
filetype off                  " 必须

" 设置包括vundle和初始化相关的runtime path
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" 另一种选择, 指定一个vundle安装插件的路径
"call vundle#begin('~/some/path/here')

" 让vundle管理插件版本,必须
Plugin 'VundleVim/Vundle.vim'

" 以下范例用来支持不同格式的插件安装.
" 请将安装插件的命令放在vundle#begin和vundle#end之间.
" Github上的插件
" 格式为 Plugin '用户名/插件仓库名'
Plugin 'tpope/vim-fugitive'
" 来自 http://vim-scripts.org/vim/scripts.html 的插件
" Plugin '插件名称' 实际上是 Plugin 'vim-scripts/插件仓库名' 只是此处的用户名可以省略
Plugin 'L9'
" 由Git支持但不再github上的插件仓库 Plugin 'git clone 后面的地址'
Plugin 'git://git.wincent.com/command-t.git'
" 本地的Git仓库(例如自己的插件) Plugin 'file:///+本地插件仓库绝对路径'
"Plugin 'file:///home/andy/path/to/plugin'
" 插件在仓库的子目录中.
" 正确指定路径用以设置runtimepath. 以下范例插件在sparkup/vim目录下
Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}
" 安装L9，如果已经安装过这个插件，可利用以下格式避免命名冲突
"Plugin 'ascenator/L9', {'name': 'newL9'}
" YouCompleteMe
Plugin 'Valloric/YouCompleteMe'
Plugin 'yggdroot/indentline'
Plugin 'jiangmiao/auto-pairs'

" 你的所有插件需要在下面这行之前
call vundle#end()            " 必须
filetype plugin indent on    " 必须 加载vim自带和插件相应的语法和文件类型相关脚本
" 忽视插件改变缩进,可以使用以下替代:
"filetype plugin on
"
" 简要帮助文档
" :PluginList       - 列出所有已配置的插件
" :PluginInstall    - 安装插件,追加 `!` 用以更新或使用 :PluginUpdate
" :PluginSearch foo - 搜索 foo ; 追加 `!` 清除本地缓存
" :PluginClean      - 清除未使用插件,需要确认; 追加 `!` 自动批准移除未使用插件
"
" 查阅 :h vundle 获取更多细节和wiki以及FAQ
" 将你自己对非插件片段放在这行之后
  • 安装插件: 运行 vim 再运行 : PluginInstall 更新 vim 插件: PluginUpdate 清理未使用都插件: PluginClean

VIM安装YouCompleteMe

上一步已经在Vundle中通过Plugin 'valloric/youcompleteme'下载好插件，但是需要手动编译安装:

(1) 进入YouCompleteMe文件夹下

cd  ~/.vim/bundle/YouCompleteMe/

(2) 编译

./install.py  --clang-completer --go-completer --ts-completer

参数--clang-completer是为了支持C/C++的补全，--go-completer是为了支持Go的补全, --ts-completer是为了支持JavaScript的补全。编译过程比较长，耐心等待。 安装的时候有报错信息：

/Library/Developer/CommandLineTools/usr/bin/ranlib: file: libBoostParts.a(windows_file_codecvt.cpp.o) has no symbols
/Library/Developer/CommandLineTools/usr/bin/ranlib: file: libBoostParts.a(icu.cpp.o) has no symbols

/Library/Developer/CommandLineTools/usr/bin/ranlib: file: libBoostParts.a(winstances.cpp.o) has no symbols

目前还没找到解决方法，不过不影响使用。

(3) 找到文件.ycm_extra_conf.py在~/.vim/bundle/YouCompleteMe/third_party/ycmd/下面:

cd ~/.vim/bundle/YouCompleteMe/thrid_party/ycmd/

ls -a 即可看到。

自行在YoucompleteMe/中创建cpp/ycm目录，将 .ycm_extra_conf.py拷贝进去:

cd ~/.vim/bundle/YouCompleteMe
mkdir cpp
mkdir cpp/ycm
cp ~/.vim/bundle/YouCompleteMe/thrid_party/ycmd/.ycm_extra_conf.py ~/.vim/bundle/YouCompleteMe/cpp/ycm/

(4) 修改.vimrc配置文件 将下面的内容添加到~/.vimrc里面:

" 寻找全局配置文件
let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py'
"let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/third_party/ycmd/.ycm_extra_conf.py'
" 禁用syntastic来对python检查
let g:syntastic_ignore_files=[".*\.py$"]
" 使用ctags生成的tags文件
let g:ycm_collect_identifiers_from_tag_files = 1
" 开启语义补全
" 修改对C语言的补全快捷键，默认是CTRL+space，修改为ALT+;未测出效果
"let g:ycm_key_invoke_completion = '<M-;>'
" 设置转到定义处的快捷键为ALT+G，未测出效果
"nmap <M-g> :YcmCompleter GoToDefinitionElseDeclaration <C-R>=expand("<cword>")<CR><CR>
"关键字补全
"let g:ycm_seed_identifiers_with_syntax = 1
" 在接受补全后不分裂出一个窗口显示接受的项
set completeopt-=preview
" 让补全行为与一般的IDE一致
set completeopt=longest,menu
" 不显示开启vim时检查ycm_extra_conf文件的信息
let g:ycm_confirm_extra_conf=0
" 每次重新生成匹配项，禁止缓存匹配项
let g:ycm_cache_omnifunc=0
" 在注释中也可以补全
let g:ycm_complete_in_comments=1
" 输入第一个字符就开始补全
let g:ycm_min_num_of_chars_for_completion=1
" 错误标识符
let g:ycm_error_symbol='>>'
" 警告标识符
let g:ycm_warning_symbol='>*'
" 不查询ultisnips提供的代码模板补全，如果需要，设置成1即可
" let g:ycm_use_ultisnips_completer=0

上面的内容中，除了第一句寻找全局配置文件，其他的语句可以根据自己的需要更改、删除或添加。 注：如果没有在第(3)步中自己创建cpp/ycm目录拷贝.ycm_extra_conf.py文件，则需要将第一句中的路径改为全局配置文件所在的具体路径，如下：

let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/thrid_party/ycmd/.ycm_extra_conf.py'

(5) 保存退出.vimrc ,打开一个C/C++源程序，体验其自动补全效果。

" 你的所有插件需要在下面这行之前
call vundle#end()            " 必须
filetype plugin indent on    " 必须 加载vim自带和插件相应的语法和文件类型相关脚本
" 忽视插件改变缩进,可以使用以下替代:
"filetype plugin on
"
" 简要帮助文档
" :PluginList       - 列出所有已配置的插件
" :PluginInstall    - 安装插件,追加 `!` 用以更新或使用 :PluginUpdate
