半夜看了本小说觉得翻页太累
首先要解决的问题是找一个质量还过得去的小说站 然后写个脚本去把它爬下来章节合并到一起
import fs from "fs"; import { argv } from "process"; import request from "request"; import cheerio from "cheerio"; import iconv from "iconv-lite"; import sanitize from 'sanitize-html'; class main { constructor() { Object.assign(this, { path: './chapter.json', html: './reader.html', url: { list: 'http://www.piaotian.net/html/6/6658/' }, store: [] }) } fetch(url, callback) { request.get(url, {encoding: null}, (error, response, body)=> { if (!error && response.statusCode == 200) { let $ = cheerio.load(iconv.decode(body, 'GBK')); callback($, body); } else { console.…Oct 11, 2015
send notification when task finish —
终端里运行长时间任务(比如 make systemimage)的时候经常会切换到其他环境做别的事情 容易忘记查看之前的任务是否完成, 查到一些方法用在任务结束时发出通知
#C-z 切到后台运行 fg; tput bel # Mac OS X #系统弹窗 osascript -e 'tell app "System Events" to display alert "Build Completed" message "The checkout and build have completed."' say "Job finished" #语音播报 #notification center osascript -e 'display notification "Job finished" with title "Alert"' sudo gem install terminal-notifier terminal-notifier -message "Job finished!" -title "Alert" # Ubuntu notify-send "Job finished!" # KDE kdialog --passivepopup 'Job finished' 还有 iterm2 trigger 也能用来触发通知, 高亮文字…Oct 4, 2015
create CNAME with internationalized domain name —
前段时间买了个 idn: yányào.com 闲置了很长时间没动 趁着十一长假无所事事的机会, 把玩了一下 hexo 挂到 yanyaoer.github.io
然后 CNAME 的时候掉坑了, 看到有人说30分钟生效傻傻等就不提了 实际上这个域名的 CNAME 内容应该用编码后的字符串而不是 yányào.com

xtag-and-shadowdom —
最近在做的项目重构, 原本打算用 reactjs, 写了一些实验代码后心累无爱 找了个 domdiff 配合自定义标签和 shadowdom 的独有作用域也是爽 YY
可惜的是测试红米上的 android webview 版本(32?)不支持 ::shadow 伪类 inline 方式覆盖样式略嫌繁琐
示例代码 xtag.js let dom = { shadow(el) { return el.createShadowRoot ? el.createShadowRoot() : el.webkitCreateShadowRoot(); }, attr(el, prefix='') { return Object.keys(el.dataset).map((d)=> `${prefix}${d}="${el.dataset[d]}"`).join(' ') } } document.registerElement('x-image', { prototype: Object.create(HTMLElement.prototype, { createdCallback: { value() { //xtag 嵌套时这里读不到attr, 放到 attach console.log('onCreate::image'); } }, attachedCallback: { value() { console.log('onAttach::image'); let shadow = dom.shadow(this); shadow.innerHTML = `<style> img { max-width: 100%; } </style> <img ${dom.…Jan 20, 2015
