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 🙏

 * 入参
 * extendedBlanks: 单空有多种答案,即等值情况  二维数组
 * groups: 多空之间支持乱序 二维数组
 * blanks 问题对应的正确答案(旧的CB数据,即字段blanks) 一维数组
 * userAnswers: 用户输入的答案 一维数组(必须传)
 * isSeq: boolean。true:结果返回由01构成的一维数组,表示每个空的正误,false:结果返回布尔值,表示该题的正误.
 * type: number, 目前只有一个枚举,1  该字段表示计算userAnswers和blanks之间是否相等的算法,1代表差集算法, 目前仅多选题用到此算法
 * 参数传入规则:1.仅兼容旧数据:userAnswers & blanks;2. 支持多答案乱序 userAnswers & extendedBlanks & groups (blanks可不传)

前端

import judge from 'katex-answer-match'
judge.katex_answer_match(
    [' 123', '123'],
    {
        extendedBlanks: [
            ['1/2', '0.5'],
            ['red', 'r'],
        ],
        groups:[
            [0, 1]
        ],
        blanks:['1/2', 'red'],
        isSeq: true
    }
);
// type = 1 差集算法, 以下示例返回[1,1,0] 表示每个blanks的元素在userAnswers中是否存在
judge(
    ['a', 'b'],
    {
        blanks: ['b', 'a', 'c'],
        isSeq: true
    },
    1
)
// type = 1 差集算法,以下示例返回了false, 表示没有完全匹配
judge(
    ['a', 'b'],
    {
        blanks: ['b', 'a', 'c']
    },
    1
