Jekyll 正在清理期间删除静态文件

Question

我想在 markdown 页面中包含一个 gnuplot 代码，并在我保存它时让 Jekyll 编译图形。正在保存图形图像。但它在 jekyll 的清理过程中被删除了。我找到的最接近解决方案的是 Copying generated files from a Jekyll plugin to a site resource folder。但是，我并不了解 Jekyll 的整体流程以及我如何防止静态文件被删除。我添加了 site.static_files << Jekyll::StaticFile.new(site, site.source, path, filename) 但没有结果。

如果我在 _site 文件夹之外创建了一个虚拟文件，Jekyll 会将我的文件安全地保存在 _site 文件中。我宁愿不必创建那个虚拟文件。

这是我的插件的代码。任何帮助都会很棒。

class RenderGNUplot < Liquid::Block
 def initialize(tag_name, markup, tokens)
  super
  @markup =  markup
  @attributes = {}
  markup.scan(Liquid::TagAttributes) do |key, value|  @attributes[key.to_sym] = value end
 end
 def gnuplot(commands)
  IO.popen("gnuplot", "w") { |io| io.puts commands }
 end
 def render(context)
  site = context.registers[:site]
  @file = ""
  commands =   super 
  if ( commands =~ /set output "(.*)"/ )
   setfile_regex = Regexp.new(/set output "((.*))"/)
   filepath = commands[setfile_regex, 1]
   @file = File.basename filepath
   commands = commands.sub!(commands[setfile_regex], 'set output "_site/media/' + @file +'"' )
   p commands 
  end
  gnuplot(commands)
  site.static_files << Jekyll::StaticFile.new(site, site.source, "_site/media/", "#{@file}")
  # site.static_files << Jekyll::StaticSitemapFile.new(site, site.dest, '/', 'sitemap.xml')
 "<object id='' type='image/svg+xml' data='#{site.baseurl}/media/{@file}'>Your browser does not support SVG</object>"
 end
end
Liquid::Template.register_tag('test', RenderGNUplot)

这正是我正在使用的代码。它只有 Liquid 块和 jekyll StaticFile

class GNUplotFile < Jekyll::StaticFile
    def write(dest)
      puts "WRITE---->>>>>>>>>>>"
      #File.write('_site/media/BTTTTT.svg', DateTime.now)
      gnuplot(@commands)
      # do nothing
    end
    def gnuplot(commands)
      IO.popen("gnuplot", "w") { |io| io.puts commands }
    end
    def givemethecommands(commands)
      @commands = commands
    end
end

class RenderGNUplot < Liquid::Block
  def initialize(tag_name, markup, tokens)
     super
     @markup =  markup
     @attributes = {}
     markup.scan(Liquid::TagAttributes) do |key, value|  @attributes[key.to_sym] = value end
  end

  def render(context)
    site = context.registers[:site]
    @file = ""
    commands =   super 
    if ( commands =~ /set output "(.*)"/ )
      setfile_regex = Regexp.new(/set output "((.*))"/)
      filepath = commands[setfile_regex, 1]
       @file = File.basename filepath
      commands = commands.sub!(commands[setfile_regex], 'set output "_site/media/' + @file +'"' )
      #p commands 
    end
    gnuplot = GNUplotFile.new(site, site.source, "_site/media/", "#{@file}")
    gnuplot.givemethecommands commands
    site.static_files << gnuplot 
    # site.static_files << Jekyll::StaticFile.new(site, site.dest, '/', 'sitemap.xml')
    "<object id='' type='image/svg+xml' data='#{site.baseurl}/media/#{@file}'>Your browser does not support SVG</object>"
  end
end
Liquid::Template.register_tag('test', RenderGNUplot)
