在octopress里面添加一个分类的时候,经常会遇到分类跟导航页面没有同步更新的情况,即加了一个分类,生成了文章,文章被生成在指定的路径下了,但是首页导航栏的分类没有跟着更新。针对这种情况,修改了一下Rakefile,把分类做成了配置,添加分类的时候可以直接修改一下分类信息,然后rake gen就可以生成对应的导航栏html代码。

修改如下(我以前增加过交互的提示选择分类的功能),需要解释的有如下几点:

  1. “——”是分割线,-的数量不能都一样,毕竟是作为map的key的。
  2. 分类做成map是因为category生成的时候名字自动做成了英文/拼音/中横线的形式…我没搞明白怎么弄的。所以自己手动填一下好了。以后有空想做成手动指定的。
  3. system sublime那个是自动打开sublime写博客。我不习惯用vim写中文的博客…

配置部分

category_path ='source/_includes/categories.html'
categories={
    "技术相关"=>{
        "软件发布"=>"ruan-jian-fa-bu",
        "---------"=>"",
        "C++"=>"c-plus-plus",
        ".Net"=>"dot-net",
        "Flex"=>"flex",
        "基础理论"=>"ji-chu-li-lun",
        "Latex"=>"latex",
        "Linux"=>"linux",
        "MFC"=>"mfc",
        "Oceanbase"=>"oceanbase",
        "分布式系统"=>"fen-bu-shi-xi-tong",
        "PHP"=>"php",
        "Java"=>"java",
        "Python"=>"python",
        "vim"=>"vim",
        "web相关"=>"web",
        "其他"=>"others",
        "----------"=>"",
        "IT人生"=>"ai-ti-ren-sheng",
    },
    "世情百态"=>"shi-qing-bai-tai",
    "摄影"=>"she-ying",
    "随笔" =>"sui-bi" }

rake gen生成导航的html的部分。

desc "Generate jekyll site"
task :gen do
    html=''
    for key,value in categories
        if value.is_a?(Hash)
            html << '<li class="dropdown">' << "\n"
            html << '<a data-toggle="dropdown" class="dropdown-toggle" href="#">%s<b class="caret"></b></a>'%[key] << "\n"
            html << '<ul class="dropdown-menu">' << "\n"
            for key,value in value
                if key.start_with?('-')
                    html << "\t"'<li class="divider"></li>' << "\n"
                else
                    html << "\t"'<li><a href="/category/%s">%s</a></li>'%[value, key.strip] << "\n"
                end
            end
            html << '</ul>' << "\n"
            html << '</li>' << "\n"
        else
            html << '<li><a href="/category/%s">%s</a></li>'%[value, key.strip] << "\n"
        end
    end
    File.open(category_path, 'w') { |file| file.write(html) }
end

交互提示分类并generate new post的部分。

# usage rake new_post[my-new-post] or rake new_post['my new post'] or rake new_post (defaults to "new-post")
desc "Begin a new post in #{source_dir}/#{posts_dir}"
task :new_post, :title, :category do |t, args|
  if args.title
    title = args.title
  else
    title = get_stdin("Enter a title for your post: ")
  end
  if args.category
    category = args.category
  else
    #output an array
      category_arr = []
      category_idx = 0
      puts "===================================================="
      for key,value in categories
          if value.is_a?(Hash)
              puts key
              for key,value in value
                  if not key.start_with?('-')
                      puts "%d\t%s"%[category_idx, key]
                      category_arr.push(key)
                      category_idx +=1
                  end
              end
          else
              puts "%d %s"%[category_idx, key]
              category_arr.push(key)
              category_idx +=1
          end
      end
      puts "===================================================="
    i = get_stdin("Enter a title for your category: ")
    category = category_arr[Integer(i)].gsub(/\s/,'')
  end

  raise "### You haven't set anything up yet. First run `rake install` to set up an Octopress theme." unless File.directory?(source_dir)
  mkdir_p "#{source_dir}/#{posts_dir}"
  filename = "#{source_dir}/#{posts_dir}/#{Time.now.strftime('%Y-%m-%d')}-#{title.to_url}.#{new_post_ext}"
  system "echo #{filename} |xclip -i -selection clipboard "
  if File.exist?(filename)
    abort("rake aborted!") if ask("#{filename} already exists. Do you want to overwrite?", ['y', 'n']) == 'n'
  end
  puts "Creating new post: #{filename}"
  open(filename, 'w') do |post|
    post.puts "---"
    post.puts "layout: post"
    post.puts "title: \"\""
    post.puts "date: #{Time.now.strftime('%Y-%m-%d %H:%M')}"
    post.puts "comments: true"
    post.puts "published: true"
    post.puts "categories: \"#{category.gsub(/&/,'&amp;')}\""
    post.puts "---"
  end
  system "LD_PRELOAD=~/repo/scripts/libsublime-imfix.so nohup ~/share/sublime/sublime_text #{filename} >/dev/null 2>&1 &"
end

修改custom/navigation.html,让导航部分导入生成的categories.html

<ul class="nav">
    <li><a href="/blog/archives">Archives</a></li>
    <li class="divider-vertical"></li>
    {\% include categories.html \%}
</ul>
