设置文章置顶 & Cloudinary在线图片服务^[1]

top: 3 # 数字越大越靠前，默认为0
除了在本地存储图片，还可以将图片上传到一些免费的CDN服务中。比如Cloudinary提供的图片CDN服务，在Cloudinary中上传图片后，会生成对应的url地址，将地址直接拿来引用即可。
在Cloudinary申请账号，上传图片(注意把upload选项中的unsigned signature选上)

Cloundinary的免费存储空间还是非常大的cloudinary价格
 我的cloudinary
使用方法：

点击图片
点击url
拷贝链接

hexo个人命令

用hexol/hexod命令一次性完成本地/远程预览
配置.bash_profile:

export HEXO='/Users/Aether/Documents/hexo_file'
export HEXOMD='/Users/Aether/Documents/hexo_file/source/_posts/'
alias hexod='cd $HEXOMD && sh tackle_md.sh && hexo clean && hexo g && hexo deploy'
alias hexol='cd $HEXOMD && sh tackle_md.sh && hexo clean && hexo g && hexo s'

tackle_md.sh自动调整缩进、设置部分显示(for next theme)

#!/bin/sh
sh indent.sh
sh read_more.sh

其中，indent.sh:

#!/bin/sh
# indent for code block
sed -i 's/^```[a-z]/   &/g' *.md
# indent for quote
sed -i 's/^>/   &/g' *.md

read_more.sh:

#!/bin/sh
# if no "<!-- more -->" in *.md file, adding it into the file.
for md_file in $(ls *md)
do
    stat=$(grep "<!-- more -->" $md_file)
    if [ -z "$stat" ];then
        sed -i '20a <!-- more -->' $md_file
    fi
done

设置social_icons
next是通过FontAwesome进行图标设计的，FA支持的图标都在主页上。
目前FA不支持知乎，所以随便选了个fa-bed作为icons。设置中写为zhihu: bed
设置文章标题的格式^[5]
~~直接用html就可以~~
~~title: <font size=6><b>人工智能简介~~
next themes的配置文件在themes/next/source/css/_variables/custom.styl

$font-size-headings-base = 28px

mathjax

hexo-renderer-mathjax: haven’t maintained since 2016.
npm install hexo-math --save
Example:
Simple inline $a_{i} = b_{i} + c_{i}$.
$$\frac{\partial u}{\partial t}
= h^2 \left( \frac{\partial^2 u}{\partial x^2} +
\frac{\partial^2 u}{\partial y^2} +
\frac{\partial^2 u}{\partial z^2}\right)$$

hexo bug

Error: Cannot find module './build/Release/DTraceProviderBindings' in OS X
1. npm install hexo --no-optional doesn’t work
2. npm un hexo-cli && npm i hexo-cli -g still encounts bugs, and it’s about dtrace-provider.
3. Then we try to install dtrace-provider:
  Error: Python executable anaconda3/bin/python is v3.5.2, which is not supported by gyp.
4. If PYTHON=python2.7 npm install dtrace-provider --save is used then a new bug will be reported:
  xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
5. This is an error about Xcode, solution link
6. Finally, this DTrace error is solved.
