Linux DIY 一个脚本壁纸工具

在Linux没找到合适的壁纸软件，于是估摸着自己简单实现了一个。

功能由三部分实现:
效果

源码如下 (相当之简陋勉强能用)

#!/usr/bin/env ruby
# encoding:utf-8
# -*- coding: UTF-8 -*-

require 'fileutils'

# 壁纸更换间隔
DURA = 30 * 60
IMGS = 2
# 图片脚本调用方式 INDEX 顺序; RANDOM 随机
FETCH = 'INDEX'
VALS = { :INDEX_FETCH => 0, :COUNT_FETCH => 0 }
# 图片临时存放路径
IMG = '/tmp/bgwall/'
FSC = './fetch_script/'
PSC = './post_script/'
CBG = "#{IMG}/bgwall_current.png"
NBG = "#{IMG}/bgwall_next.png"


def call_bg_script(script, img_dir, count)
return nil if script.nil?
file = `#{script[0]} #{img_dir}/#{script[1]}_#{count} #{count}`.chomp
puts ">>> bg [#{file}] fetch by #{script[1]}"
return file
end

def call_post_script(img_path)
Dir::open(PSC).filter{|f| f.start_with? /\d+/ and File.executable? PSC + f }.sort.map{|v| [PSC + v, v] }.each_with_index do |script,index|
  nName = "#{IMG}#{index}_#{File.basename(img_path)}"
  FileUtils.copy_file img_path, nName
  system("#{script[0]} #{img_path} #{nName}")
  img_path = nName
end
return img_path
end

def get_background_image(fetch_type)
VALS[:COUNT_FETCH] += 1
fsca = Dir::open(FSC).filter{|f| f.start_with? /\d+/ and File.executable? FSC + f }.sort.map{|v| [FSC + v, v] }
return nil if fsca.empty?
call_bg_script case fetch_type
when 'RANDOM'
fsca[ rand fsca.size ]
when 'INDEX'
VALS[:INDEX_FETCH] += 1
fsca[ VALS[:INDEX_FETCH] % fsca.size ]
else
fsca[ rand fsca.size ]
end, IMG, VALS[:COUNT_FETCH]
end

def set_background_image(img_path)
# 根据不同的环境 使用不同的 工具
#system("hsetroot -fill #{img_path}")
puts ">>> set background #{img_path} [#{Time.now}]\n\n"
system("feh --bg-scale #{img_path}")
end



`[[ -d #{IMG} ]] || mkdir #{IMG}; echo $(date) > #{PSC}/start && echo $(date) > #{FSC}/start; sleep 2`

# 每分钟刷新一次桌面背景 主要更新图片处理进本的操作，比如刷新显示时间
Thread::new do
loop do
  if Time.now.sec == 00
    next if not File.exist? CBG
    if File.exist? NBG
      set_background_image NBG
    else
      set_background_image CBG
    end
    post_bg = call_post_script CBG
    FileUtils.copy_file post_bg, NBG
  end
  sleep 1
end
end

# 间隔时间后 拉取新壁纸
loop do
sleep 7 if Time.now.sec == 00
file = get_background_image FETCH
FileUtils.copy_file file, CBG if not file.nil?
next if not File.exist? CBG

sleep DURA
end

时间脚本

#!/usr/bin/env zsh

# $1 源图片路径
# $2 存放路径
_dz=("子" "丑" "寅" "卯" "辰" "巳" "午" "未" "申" "酉" "戌" "亥")
now=$(date "+%H")
dz=$_dz[$[ ($now + 1) / 2 % 12 + 1]]"   時"
now=$now":"$[ $(date "+%M") + 1]
convert $1 -font Noteworthy-Bold.ttf -gravity SouthEast -pointsize 200 -fill white -annotate +100+100 "$now" $2
convert $2 -font /usr/share/fonts/wps-office/FZLSK.TTF -gravity SouthEast -pointsize 200 -fill white -annotate +100+500 "$dz" $2

拉取脚本

#!/usr/bin/env zsh

# $1 存放路径
# $2 当前脚本的调用次数
base_page="https://wallhere.com/zh/wallpapers?q=狗&page=$2&pageSize=1&format=json"
data_id=$(curl $base_page | jq .data | sed  -e 's/\\r\\n//g' -e 's/\\//g' | grep -Po '(?<=data-id=")(\d+?)(?=")' | head -n1)
img_url="https://wallhere.com/zh/wallpaper/$data_id"
img_src=$(curl $img_url | grep current-page-photo | grep -Po '(?<=href\=")(.*?)(?=")')

wget $img_src -O $1.jpg
echo $1.jpg

或者

#!/usr/bin/env zsh
# $1 存放路径
# $2 当前脚本的调用次数

echo "/home/user/Pictures/background.png"
