新功能开发方面的似乎变动不大.\r\n
从目前的使用来看,在osx下稳定性还不错.可用度也很高\r\n
窃以为, 已经可以作为开发环境来了.\r\n
btw.前几天出了个missing headers files的编译问题\r\n
\r\n
这里把v0.5引入的新功能做了各简单的汇总.\r\n
\r\n

buffer.readInt8(offset, endian)

buffer.readInt16(offset, endian)

buffer.readInt32(offset, endian)

buffer.readFloat(offset, endian)

buffer.readDouble(offset, endian)

buffer.writeUInt8(value, offset, endian)

buffer.writeUInt16(value, offset, endian)

\r\n

buffer填充

\r\n

buffer.fill(value, offset=0, length=-1)

\r\n
\r\n

Child Process

\r\n

child_process.fork

\r\n

\r\n

\r\n
// master.js\r\n
var cp = require('child_process');\r\n
var n = cp.fork(__dirname + '/child.js');\r\n
n.on('message', function(m) {\r\n
  console.log('PARENT got message:', m);\r\n
});\r\n
n.send({ hello: 'world' });\r\n
\r\n
// child.js\r\n
process.on('message', function(m) {\r\n
  console.log('CHILD got message:', m);\r\n
});\r\n
process.send({ foo: 'bar' });\r\n

\r\n
\r\n

\r\n
define(function (require, exports, module) {\r\n
\tvar PI = Math.PI;\r\n
\t exports.area = function (r) {\r\n
\t\treturn PI * r * r;\r\n
\t};\r\n
\t exports.circumference = function (r) {\r\n
\t\treturn 2 * PI * r;\r\n
\t};\r\n
});\r\n
