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 🙏

cmd-interface

travis

cmd-interface提供一种简单快速的方式来创建一个命令行交互式界面,通过简单的设置就可以获得强大的交互界面,并提供相关的交互函数。

##安装

npm install cmd-interface

##简单配置

#!/usr/bin/env node

var Commander = require('cmd-interface').Commander;

var cmd = new Commander({
	name: 'cmd-interface'
});

cmd.option({
	cmd: '-s,--save',
	description: 'save something infomation',
	handler: function(parse) {
		conosle.log('save handler!');
	}
});

cmd.option({
	cmd: '-H,--hidden',
	description: 'hidden option',
	visible: false,
	handler: function(parse) {
		conosle.log('hidden handler!');
	}
});


cmd.command({
	cmd: 'start',
	description: 'start server',
	handler: function(parse) {
		console.log('start server!');
	}
});

cmd.version('0.0.1');
cmd.run();

运行后可见界面

  Usage: cmd-interface <command>

  Command:

    start                         start server                  

  Option:

    -s,--save                     save something infomation     
    -v,--version                                                

Commander继承自EventEmitter,可以通过添加事件的方式来添加handler

cmd.on('start', function(parse) {
    console.log('  start handler again!');
});

事件名同传入cmd.command的cmd参数,添加option的handler事件名为全称且中间不能有空格

cmd.on('-s,--save', function(parse) {
    console.log('  save handler again!');
});

parse为parseArgv()函数解析返回的对象

option()、command()都可以通过传入参数visible=false不在输出help

cmd.option({
	cmd: '-H,--hidden',
	description: 'hidden option',
	visible: false,
	handler: function(parse) {
		conosle.log('save handler!');
	}
});
cmd.command({
	cmd: 'stop',
	description: 'stop server',
	visible: false,
	handler: function(parse) {
		console.log('stop server!');
	}
});

设置版本号

cmd.version('0.0.1');

输出help

cmd.help();

Util

util提供交互函数

var util = require('cmd-interface').util;

####parseArgv

解析process.argv,返回格式如下

 var argv = util.parseArgv(['-a', 'b', 'c', '-d=e', '--f=g', 'h', 'i']);
 return {
 	'-': ['h', 'i'],
 	'a': ['b', 'c'],
 	'd': ['e'],
 	'f': ['g']
 }

####read

命令行交互函数

 util.read('input something', function(data) {
    conosle.log(data);
 });

####printfFormat

提供类似c的printf格式化函数,可以设置宽度,%s、$d、$j参数参看util.format

 var read = util.printfFormat('%4s%s4', '$', '$');
 read = '$      $'
