搭建基于haskell的静态博客程序heckle

先按此文http://briteming.blogspot.com/2016/07/haskellghc.html安装cabal.

cd /usr/local
git clone https://github.com/2016rshah/heckle heckle-blog-by-2016rshah
cd heckle-blog-by-2016rshah (因为当前目录下有cabal文件，于是运行cabal sandbox init）
cabal sandbox init
cabal install

等待安装完成后，进入.cabal-sandbox/bin/目录，.cabal-sandbox/bin/目录里有heckle文件，这个heckle文件就是本程序的可执行文件，其完整路径为/usr/local/heckle-blog-by-2016rshah/.cabal-sandbox/bin/heckle ，
另外一个可执行文件为/usr/local/heckle-blog-by-2016rshah/dist/dist-sandbox-9ebc2966/build/heckle/heckle，这2个可执行文件是等效的。

root@AR:/usr/local/heckle-blog-by-2016rshah# ls
example       heckle.cabal  Setup.hs
cabal.sandbox.config  heckle       meta         src
README.md     stack.yaml
root@AR:/usr/local/heckle-blog-by-2016rshah# mkdir heckle-blog
root@AR:/usr/local/heckle-blog-by-2016rshah# cd heckle-blog
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog#  /usr/local/heckle/.cabal-sandbox/bin/heckle init
(此命令会在当前目录下，生成博客目录结构）
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog# ls
index.html  index.html.hkl  posts  template.html.hkl
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog# cd posts
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog/posts# ls
example-markdown.html  example-markdown.md
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog/posts# nano test-1.md
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog/posts# cat test-1.md

这是测试1.

看看如何？
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog/posts# cd ..
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog#  /usr/local/heckle-blog-by-2016rshah/.cabal-sandbox/bin/heckle build
(此即生成静态网站的根目录的命令）
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog# ls
index.html  index.html.hkl  posts  template.html.hkl
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog#
(可见此处，/usr/local/heckle/heckle-blog就是静态网站的根目录，不过这个/usr/local/heckle/heckle-blog/所对应的网站很简陋）
root@AR:/usr/local/heckle-blog-by-2016rshah/heckle-blog# cd ..

我们来克隆程序作者的网站：
root@AR:/usr/local/heckle-blog-by-2016rshah# git clone https://github.com/2016rshah/blog 2016rshah-blog
root@AR:/usr/local/heckle-blog-by-2016rshah# cd 2016rshah-blog
root@AR:/usr/local/heckle-blog-by-2016rshah/2016rshah-blog# ls
discarded_posts  index_files  index.html.hkl  README.md  template.html.hkl
fonts         index.html   posts          resources
root@AR:/usr/local/heckle-blog-by-2016rshah/2016rshah-blog# cd posts
root@AR:/usr/local/heckle-blog-by-2016rshah/2016rshah-blog/posts# nano test-1.md
root@AR:/usr/local/heckle-blog-by-2016rshah/2016rshah-blog/posts# cat test-1.md

# 测试1

这是测试1.

看看如何？
root@AR:/usr/local/heckle-blog-by-2016rshah/2016rshah-blog/posts# cd ..
root@AR:/usr/local/heckle-blog-by-2016rshah/2016rshah-blog# /usr/local/heckle-blog-by-2016rshah/.cabal-sandbox/bin/heckle build

注：如果你安装了latex,这个博客程序还可生成pdf文件。只要你新建的源帖为tex文件，就可把tex文件转化为pdf文件。
root@AR:/usr/local/heckle-blog-by-2016rshah/2016rshah-blog# cd posts
root@AR:/usr/local/heckle-blog-by-2016rshah/2016rshah-blog/posts# ls
