Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

pyfl

v2.0.0

Published

获取拼音首字母

Readme

pyfl 是一个面向浏览器的拼音首字母转换库。传入一段文本,它会逐字转换其中的常用汉字,并原样保留英文、数字、空格和符号。

适合用来生成搜索索引、通讯录首字母和中文标题缩写。它不做分词、多音字推断或完整拼音转换,只专注于快速得到首字母。

安装

yarn add pyfl

也可以使用 npm:

npm install pyfl

使用

import pyfl from "pyfl";

pyfl("喵");                    // "M"
pyfl("你好,世界");             // "NH,SJ"
pyfl("Made by ❤");            // "Made by ❤"
pyfl("好笑吗跟傻子一样整天就知道哈哈哈哈哈哈哈");
// "HXMGSZYYZTJZDHHHHHHH"

CommonJS 项目需要读取默认导出:

const pyfl = require("pyfl").default;

转换规则

  • 常用汉字转换为大写拼音首字母
  • 英文、数字、空格和符号保持不变
  • 空字符串或只包含半角空格的字符串返回空字符串
  • 非字符串输入会先通过模板字符串转换为文本
pyfl(123456);    // "123456"
pyfl(undefined); // "undefined"
pyfl(null);      // "null"

从源码构建

git clone https://github.com/yuxino/pyfl.git
cd pyfl
yarn
yarn test
yarn build

pyfl 最初为 WeChat 项目而写,字典实现改编自 pinyinjs

说明

  • 转换基于内置字典,不会发起网络请求
  • 多音字按字典中的固定读音处理,不结合上下文推断
  • 当前字典覆盖 Unicode U+4E00U+9FA5 范围内的汉字;范围外字符保持原样
  • 欢迎通过 Issue 补充缺字或报告错误读音
