Octopress提供很多的Rake任务去创建post和pages，他还会根据你的posts来生成Category，你可以在atom.xml或者blog/categories/<category>/atom.xml中找到这些内容

####Post

这些Post页面必须存放在Source/_posts目录下面，并且命名方式和jekyll的命名方式一样，会转换成YYYY-MM-DD-Post-title.markdown，这个文件的名字就是你的blog的url slug，日期帮助你排序这些文章

1	rake new_post["Title"]

在使用了ZSH的话，你要这样创建

1	rake new_post或者rake new_post[\"Title\"]

例如

1 2	rake new_post["Zombie Ninjas Attack: A survivor's retrospective"] Creates source/_posts/2011-07-03-zombie-ninjas-attack-a-survivors-retrospective.markdown

~/Code/rails/octopress(branch:source) » rake new_post                        
Enter a title for your post: blog-with-github-4
mkdir -p source/_posts
Creating new post: source/_posts/2013-06-03-blog-with-github-4.markdown

生成的内容大致如下

---
layout: post
title: "Zombie Ninjas Attack: A survivor's retrospective"
date: 2011-07-03 5:59
comments: true
external-url:
categories:
---

你可以关闭comments，或者为他添加categories的tag，并且你还可以添加author: Your Name与published: false来控制是否发布

####Page

生成Page的命令

rake new_page[super-awesome]
# creates /source/super-awesome/index.markdown

rake new_page[super-awesome/page.html]

如果使用了zsh的话，方法要参照post的创建方式

生成的pages的默认内如大致如下

---
layout: page
title: "Super Awesome"
date: 2011-07-03 5:59
comments: true
sharing: true
footer: true
---

####Content

如果列表中不想显示全文内容的话，可以添加标签，这将在文章下面生成一个“Continue →” 链接，链接到全文的地址

###Generate & Preview

1
2
3

rake generate   # Generates posts and pages into the public directory
rake watch      # Watches source/ and sass/ for changes and regenerates
rake preview    # Watches, and mounts a webserver at http://localhost:4000

本地使用http://localhost:4000就可以访问了

blog with github(3)-Octopress配置

Octopress的配置相当的简单，并且一般配置完成后，你不需要再对Rakefile和_config文件进行修改，下面这些是Octopress的配置文件

_config.yml       # Main config (Jekyll's settings)
Rakefile          # Configs for deployment
config.rb         # Compass config
config.ru         # Rack config

Rakefile大多是与部署相关的配置,如果不需要同步的话，你就不需要进行修改

####Blog配置

_config.yml有三部分配置,你必须修改url，并且title，subtitle和author也要修改，还有一些第三方的服务需要启用

#####主配置

url:                # For rewriting urls for RSS, etc
title:              # Used in the header and title tags
subtitle:           # A description used in the header
author:             # Your name, for RSS, Copyright, Metadata
simple_search:      # Search engine for simple site search
description:        # A default meta description for your site
date_format:        # Format dates using Ruby's date strftime syntax
subscribe_rss:      # Url for your blog's feed, defauts to /atom.xml
subscribe_email:    # Url to subscribe by email (service required)
category_feeds:     # Enable per category RSS feeds (defaults to false in 2.1)
email:              # Email address for the RSS feed if you want it.

#####Jekyll&Plugins

root:               # Mapping for relative urls (default: /)
permalink:          # Permalink structure for blog posts

destination:        # Directory for generated site files
plugins:            # Directory for Jekyll plugins
code_dir:           # Directory for code snippets (for include_code plugin)
category_dir:       # Directory for generated blog category pages

pygments:           # Toggle python pygments syntax highlighting
paginate:           # Posts per page on the blog index
pagination_dir:     # Directory base for pagination URLs eg. /blog/page/2/

blog with github(2)-部署到github

###使用github pages

如果想使用 http://username.github.io 的域名作为你的blog地址的话，首先要创建一个仓库，名字为你的用户id.github.io（比如我的是welsonla.github.io）

用户使用的是Github Pages的master版本下面的public作为你的网站主目录，你可以通过浏览http://username.github.io 来查看。如果你想在source这个版本上面维护代码，并且把内容提交到master分支，Octopress有一个命令来帮助你完成这些

1	rake setup_github_pages

然后，他将

询问你的github pages的url
将远程的重‘origin’重命名为‘octopress’
在远程的origin讲你的github pages仓库添加进去
切换当前branch从master切换到source
根据你的仓库名，重新配置你的blog地址
在_deploy目录下面设置master分支，用于部署

接下来执行

1
2
3

rake generate
rake deploy

这将生成你的blog，并将生成的文件copy到_deploy目录下面,并添加到git，将他们commit和push到master分支上面，稍后，你会收到一份来自github的email告诉你，你的提交已经收到，并且很快将发不到你的web上面

并且，不要忘记提交你的代码到source分支

1
2
3

git add .
git commit -m 'your message'
git push origin source

####自定义域名绑定

首先你要source目录下面创建一个CNAME，

1	echo 'your-domain.com' >> source/CNAME

之后去你的域名服务商或者你的dns服务商那里创建一条CNAME记录，记录指向的IP为
(不要使用顶级域名指向到pages,要使用二级域名)

1	207.97.227.245

different of class and category

当需要重写父类中的方法时，这时候定义子类

@interface JADanSideController : JASidePanelController


@end


@implementation JADanSideController

- (UIBarButtonItem *)leftButtonForCenterPanel{
    
    UIButton *leftBarButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [leftBarButton setFrame:CGRectMake(0, 0, 44, 30)];
    [leftBarButton setBackgroundImage:[UIImage imageNamed:@"List_NaviSide.png"] forState:UIControlStateNormal];
    [leftBarButton addTarget:self action:@selector(toggleLeftPanel:) forControlEvents:UIControlEventTouchUpInside];
    __autoreleasing UIBarButtonItem *leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:leftBarButton];

    return leftBarButtonItem;
}

@end

当需要为父类添加方法时，这时候定义类别

@interface JADanSideController : JASidePanelController

生成 github SSH keys

本文主要来自github官方，Generating SSH Keys


cd ~/.ssh

ssh-keygen -t rsa -C "your_email@example.com"

下面的步骤可以只敲回车进行确认即可

Creates a new ssh key using the provided email

Generating public/private rsa key pair.

#这里直接回车就会生成一个默认名为id_rsa
Enter file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]


#这里需要你输入一个你加密的key（一定要记住）
Enter passphrase (empty for no passphrase): [Type a passphrase]
Enter same passphrase again: [Type passphrase again]


Your identification has been saved in /Users/welsonla/.ssh/id_rsa.
Your public key has been saved in /Users/welsonla/.ssh/id_rsa.pub.
The key fingerprint is:
30:e8:aa:08:ee:bc:76:88:2c:3f:83:39:b0:6e:95:cc wyc.jar@gmail.com
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
|     .           |
|    . o          |
|   .   o         |
|  o o   S        |
|.  E             |
|=++              |
|%*o.             |
|OO+o             |
+-----------------+

看到这个界面说明生成成功

copy加密字符到剪切板

1	pbcopy < ~/.ssh/id_rsa.pub

打开你的github

1. 点击 Account Settings
2. 点击左侧 "SSH Keys" 
3. 点击 "Add SSH key"
4. 粘贴你的可以到 "Key" 输入框
5. 点击 "Add key"
6. 输入你的github密码确认

使用RVM安装ruby

今天突然发现ruby版本不小心又回到了1.8.7，可能是我修改了rvm的配置文件导致的，于是开始折腾安装rvm和ruby

首先还是先安装Homebrew吧
很简单，一行代码搞定

1	ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

安装RVM

1	curl -L https://get.rvm.io \| bash -s stable --ruby

走着走着发现出错了

Missing required packages: autoconf, automake, libtool, pkg-config, libyaml, readline, libxml2, libxslt, libksba, openssl, sqlite.
RVM autolibs is now configured with mode '2' => 'check and stop if missing',
please run `rvm autolibs enable` to let RVM do it's job or run and read `rvm autolibs [help]`
or visit https://rvm.io/rvm/autolibs for more information.
There were package installation errors, make sure to read the log.
Check Homebrew requirements https://github.com/mxcl/homebrew/wiki/Installation

透过错误信息，发现缺少一写依赖的包，和rvm的autolibs没打开，这时候我们就通过Homebrew先安装上（具体你要看清楚你缺少的是什么）

1
2
3

rvm autolibs enable
rvm reload
brew install autoconf automake libtool pkg-config libyaml readline libxml2 libxslt libksba openssl sqlite

漫长的等带后，依赖包终于装完了
再次安装RVM

1	curl -L https://get.rvm.io \| bash -s stable --ruby

就会安装成功，你可以rvm -v查看下版本

安装并设置1.9.3为你的默认版本

1
2
3

rvm install 1.9.3
rvm use 1.9.3
rvm rubygems latest

Finish
