powerlevel10k设置及客制化

Powerlevel10k¶

Powerlevel10k is a theme for Zsh. It emphasizes speed, flexibility and out-of-the-box experience.

安装¶

使用操作系统软件管理器安装Zsh。

安装Oh-My-Zsh主题¶

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

wget不能走sock代理，推荐使用curl下载。

基于Oh-My-Zsh的安装¶

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git $ZSH_CUSTOM/themes/powerlevel10k

设置主题¶

在.zshrc文件中设置主题

ZSH_THEME="powerlevel10k/powerlevel10k"

生成配置文件¶

使用p10k configure配置Powerlevel10k。会自动根据选项生成.p10k.zsh文件。根据喜好设置配置文件。

 )

默认情况下context组件不显示，需要修改才能显示：

##################################[ context: user@hostname ]##################################
  # Context color when running with privileges.
  typeset -g POWERLEVEL9K_CONTEXT_ROOT_FOREGROUND=178
  # Context color in SSH without privileges.
  typeset -g POWERLEVEL9K_CONTEXT_{REMOTE,REMOTE_SUDO}_FOREGROUND=180
  # Default context color (no privileges, no SSH).
  typeset -g POWERLEVEL9K_CONTEXT_FOREGROUND=180

  # Context format when running with privileges: bold user@hostname.
  typeset -g POWERLEVEL9K_CONTEXT_ROOT_TEMPLATE='%B%n@%m'
  # Context format when in SSH without privileges: user@hostname.
  typeset -g POWERLEVEL9K_CONTEXT_{REMOTE,REMOTE_SUDO}_TEMPLATE='%n@%m'
  # Default context format (no privileges, no SSH): user@hostname.
  typeset -g POWERLEVEL9K_CONTEXT_TEMPLATE='%n@%m'

  # Don't show context unless running with privileges or in SSH.
  # Tip: Remove the next line to always show context.
  # 在这里开启了context一直显示的选项
  #typeset -g POWERLEVEL9K_CONTEXT_{DEFAULT,SUDO}_{CONTENT,VISUAL_IDENTIFIER}_EXPANSION=

  # Custom icon.
  # typeset -g POWERLEVEL9K_CONTEXT_VISUAL_IDENTIFIER_EXPANSION='⭐'
  # Custom prefix.
  # typeset -g POWERLEVEL9K_CONTEXT_PREFIX='%246Fwith '

默认情况的IP组件无法显示，需要配置相应的网卡信息：

# Show information for the first network interface whose name matches this regular expression.
 # Run `ifconfig` or `ip -4 a show` to see the names of all network interfaces.
 typeset -g POWERLEVEL9K_IP_INTERFACE='wlp2s0*'

自己扩展功能的方式就是以shell中函数的方式定义。函数名需要以prompt_my_作为前缀。在前面的设置中直接写之后的函数就行。显示必须依托p10k segment才能显示在主题中。可以使用p10k help segment获取使用方法。

修改显示的系统图标：

#################################[ os_icon: os identifier ]##################################
# OS identifier color.
typeset -g POWERLEVEL9K_OS_ICON_FOREGROUND=255
# Make the icon bold.
#typeset -g POWERLEVEL9K_OS_ICON_CONTENT_EXPANSION='%B${P9K_CONTENT}'
# 修改显示的系统图标为Arch
typeset -g POWERLEVEL9K_OS_ICON_CONTENT_EXPANSION=%B$'\uF303 '     

'\uF303'为Arch图标，'\uF17c'为Linux图标。后面如果显示字符位不足的时候在编码后添加适量空格，%B表示加粗。

自定义的问候语程序¶

实现思路：通过date程序获取当前小时数。通过小时数判断当前是哪一个时间段。

function prompt_Greeting() {
    local hour=`date "+%H"`
    local name=",king"
    if [ $hour -lt 12 -a $hour -gt 4  ]
    then 
        local str="Morning"
    elif [ $hour -eq 12 ]
    then
        local str="Noon"
    elif [ $hour -gt 12 -a $hour -lt 19 ]                                                                            
    then
        local str="Afternoon"
    else
        local str="Evening"
    fi
    p10k segment -f 208 -i '㋡' -t $str$name 
  }

自定义的显示当前天气的程序¶

实现思路：先查询电脑是否连接网络。若连接，去/tmp路径中查找是否有一年中相同天数相同小时的文件。这个路径下的文件在关机后自动删除，所以在这不考虑重复的可能。每小时去获取一次当前天气。避免频繁获取造成的终端响应缓慢。获取后写入文件中，同一小时内，天气信息从文件中获取。

function prompt_my_weather() {
    ping -c1 114.114.114.114 &> /dev/null
    if [ $? -eq 0 ]
    then
        local weatherDay=`date "+%j"`
        local weatherHour=`date "+%H"`
        local weatherPath="/tmp/"
        local weatherName="my_weather"
        local weatherFileType=".txt"
        local weatherFile=$weatherPath$weatherName$weatherDay$weatherHour$weatherFileType
        if [ ! -e $weatherFile -o ! -s $weatherFile ]
        then
            touch "$weatherFile"
            local weather=`curl -s "wttr.in/?format=3 "`
            echo $weather > $weatherFile
        else
            local weather=$(cat $weatherFile)
        fi
    else
        local weather="无网络"
    fi
    p10k segment -f '#ffb44b' -t $weather

 }
