The Push to Ban Ransom Payments Is Gaining Momentum
Ransomware costs victims an estimated $30 billion per year and has gotten so out of control that global support for banning payments is gaining momentum.
velocityjs
Advanced tools
Readme
velocity.js是velocity模板语法的javascript实现。
##Features
##Install
via npm:
$ npm install velocityjs
##Broswer
兼容支持es5的浏览器,可以通过测试来验证test case。
对于低端浏览器需要实现以下方法
##Examples
在tests目录下有大量的例子,node和浏览器下使用是一致的,另外,examples目录下有一个 最简单的例子。
##Public API
文件组织通过CommonJS方式,对于浏览器,通过spm可以打包为cmd模块。
var Velocity = require('velocityjs');
//1. 直接解析
Velocity.render('string of velocity', context, macros);
//2. 使用parse和Compile
var Compile = Velocity.Compile;
var asts = Velocity.parse('string of velocity');
(new Compile(asts)).render(context, macros);
####context
context
是一个对象,可以为空,执行中$foo.bar
,访问路径是context.foo.bar
,
context
的属性可以是函数,和vm中定义保持一致。
context中得函数,有一个固定的eval
方法,可以用来运算vm语法字符串,比如webx对应的
$control.setTemplate
的实现。
##Syntax
具体语法请访问官网文档:velocity user guide。
###Directives
Directives支持set
, foreach
, if|else|elseif
, macro
, break
。不
支持有,stop
, evaluate
, define
, parse
。不过可以通过context来实现,比如
parse
实现。
###macro与parse
宏分为系统的宏,比如parse, include
,和用户自定义宏,通过#macro
在vm中定义,此
外可以使用自定义的js函数替代在vm中定义。对于系统宏和自定义宏,不做区分,对于
#parse
和#include
的调用,可以使用自定义函数来执行,可以参考测试用例中self defined macro部分。
