TheOnly92

开始下起的绵绵细雨
就好比银色的绸缎
垂落下来
将窗口掩上
那就是我的初恋

伏在地上等待的
第二个路口
没被任何人理睬
往下一看
绣球花也在哭泣

即使这么想见你
即使这么爱你
你也只在眼前路过
就算是如此
我也一直望着你
从这个地方
即使这么想见你
即使这么爱你
你也不肯向这里望一下
明明在撑着雨伞
脸颊会湿
是没有任何办法
爱恨交织的眼泪

我一个人开始步行
残留着悲伤的道路
我的心中
开始迷惑
是谁也不知道的爱情

喜欢雨的
这个绣球花
在晴天时将眼睛闭上
是否在想着
遥远的雨云？

无论如何伤心
无论如何不可能
请让我保持着少女的心怀
和你相遇
记忆的足迹
我不会忘记
无论如何伤心
无论如何不可能
以后总会回忆起来吧
我的愿望
即使不能实现
也会持续闪烁
爱恨交织的恋爱

即使这么想见你
即使这么爱你
你也只在眼前路过
就算是如此
我也一直望着你
从这个地方
即使这么想见你
即使这么爱你
你也不肯向这里望一下
明明在撑着雨伞
脸颊会湿
是没有任何办法
爱恨交织的眼泪

正在等待夏天的
天空和太阳和水平线
我一个人带着小狗
在白色的沙滩走着

海边的屋子的骨架
虽然至今还未完成
就好像过去的爱情
隐约还惦挂着

和你吃过的玉蜀黍
内部好像没有熟透
两人一起忍不住笑出来的
笑声很令人怀念

对风的下落
终于注意到了
你的笑脸
让我的伤痛都痊愈
对风的下落
充满了回忆
在我身边 你已经不在
谁能够让我的伤痛痊愈？
没有任何办法
好寂寞

长长的一年过去了
雨季也停就是耀眼的季节
波浪也将湿了的衣服脱掉
寻找那一天的波纹

你说不想被太阳晒黑
将帽子带的遮住了眼睛
亲吻的时候被阻挡了
我尴尬的抱着你

云也飘了
夏天也接近了
在心中深处的天气预告
显示着反气旋
云也飘了
你最爱的
烟花的照片如果想再拍的话
今年再来就好了
分手的理由
就忘了吧…

波浪拍着沙滩时
好像消失了一样
在沙滩上画出的心形和
你的足迹
I miss you!

对风的下落
终于注意到了
你的笑脸
让我的伤痛都痊愈
对风的下落
充满了回忆
在我身边 你已经不在
谁能够让我的伤痛痊愈？
没有任何办法
好寂寞

究竟要有多少个明天
才能够到达
在眼前 宽敞的道路
那遥远的彼方…
如果在途中停止
那梦想 就会到此结束
不管是多长的路程
都会有个开始
TRUE ROAD

张开的手掌
无法装下任何沙粒
但是只要用力 握紧拳头
就可以不放弃任何事情继续下去
从少年时期
一直 无法忘记
我愿望的沙粒
什么都没有变
如今也还在

有些时候 雨会倾盆
风也会吹起
即使心被悲伤沾满
即使迷失了方向…
找得见的光芒
要到处去寻找
微笑着的朋友 就在身边
将手伸出
TRUE FRIEND

有些人的手掌
一直都非常温暖
将一起生活的这段日子
照得如同太阳一般
流眼泪这件事
并不是什么害羞的事情
我愿望的沙粒
为了让花绽开
下起了雨

如同世界的人数
手掌和愿望也那么多
如果开始相信
那么就不会有争执…
TRUE LIFE

自己的手掌
究竟紧握着些什么？
放松 如果将手掌打开
就能看见当时下定的决心
为了成为大人
如同溢出来般的疑问
为什么会活着？
问一问沙粒
我为什么在这儿…

Disclaimer: This article is not and does not intend to be an introduction to the Go programming language.

Recently I’ve been learning the Go language created by Googlers, it’s a nice and elegant new language that seems to have a bright future.

Coming from a PHP background, there are a few things that I totally don’t understand (initially). PHP is a loosely typed programming language, you can convert int to string anytime anywhere and convert back as well. It’s the first time I meet up with a static typing language, that caused me quite some trouble in the beginning but I have been getting used to it ever since (and maybe beginning to appreciate it as well).

Besides that I have totally no concept about pointers as well, I’ve dealt them a little in PHP but in other languages like C, C++ it’s all about pointers. That makes it difficult for me. Luckily, Go has very little to do with pointers, I was quite relieved when I knew about that.

PHP array equivalence

Well, there are arrays in Go, but they’re different from PHP. For instance, to create an array one can do something like this:

It is possible to append to an array directly with $array[] and you don’t have to initialize nor declare the length of the array before you use it. In Go it’s a totally different thing (basically, in all other languages it is a totally different thing), you need to declare and initialize the array before use.

Note that you can’t just append items to arrays with tmpArray[], you have to specify an index. But what if I don’t know exactly how big my array is gonna be? That’s when you should use slice. A slice allows you to dynamically extend your arrays, and make it as long as possible.

Note that I declared and initialized a tmpArray with 0 length, then I looped 10 times and added items to it. But I suppose that this operation is expensive because if you need to extend the slice’s size it will initialize a new slice with the larger length, copy all items over and give it back to you, so it’s always good to either determine how large you need the slice to be before you begin.

What about associative arrays? Associative arrays in PHP are extremely useful and I personally use them all the time. In Go however, they aren’t called arrays, they’re maps.

To initialize a map, you do make(map[string]string), code example as below:

Notice that you can assign new items right away. If you want to assign when you declare the variable, you can do so:

A very handy and useful functionality in Go.

Regular Expressions In Go

I can’t cover too much in this area, as I have also yet to explore on regular expressions in Go yet. But I can provide some basic information on how to use regular expressions in Go.

In PHP, we do preg_match("/([a-zA-Z0-9]+)/", $string, $results) to find all alphanumeric characters. The equivalence in Go is the following:

You then have all the matches in match, which is an array of type [][]string, all the match results are stored in match[1] just like in php. Besides FindStringSubmatch, there are still a lot of functions you should read the documentation.

isset()

Performing an operation on an uninitialized variable will cause the whole program to terminate immediately. PHP has a useful function called isset(), but how do we use the equivalent on Go?

It turns out, in Go, assignments actually return 2 variables. The 2nd variable indicates if the operation is a success. So if you’re not sure whether the variable notSet is set or not, do the following:

Conclusion

The only painful part of transitioning from PHP to Go is that every time you make some changes you have to recompile it to see the effect. In PHP you just have to tap Cmd+R in your browser to see the changes in effect. Besides that, resources on the Go programming language is still scarce and libraries aren’t quite available yet.

Other than that, I don’t see any reasons why we shouldn’t use Go.
