在Ruby中带有html标签的ANSI转义码？

Question

有趣的是,Ruby中有内置的ansi转义码.

宝石还有一个更强大的版本.

不幸的是,这些日志输出到控制台.我的文本显示在页面中,所以我需要HTML标签来包裹我的文本.

你们有任何想法如何去做吗？

我想你想要的是从转义字符转换为HTML.

通过为转义字符假设以下代码/颜色哈希,我做了一次:

{ :reset          =>  0,
  :bright         =>  1,
  :dark           =>  2,
  :underline      =>  4,
  :blink          =>  5,
  :negative       =>  7,
  :black          => 30,
  :red            => 31,
  :green          => 32,
  :yellow         => 33,
  :blue           => 34,
  :magenta        => 35,
  :cyan           => 36,
  :white          => 37,
  :back_black     => 40,
  :back_red       => 41,
  :back_green     => 42,
  :back_yellow    => 43,
  :back_blue      => 44,
  :back_magenta   => 45,
  :back_cyan      => 46,
  :back_white     => 47}

我所做的是以下转换(远离无论如何优化):

def escape_to_html(data)
  { 1 => :nothing,
    2 => :nothing,
    4 => :nothing,
    5 => :nothing,
    7 => :nothing,
    30 => :black,
    31 => :red,
    32 => :green,
    33 => :yellow,
    34 => :blue,
    35 => :magenta,
    36 => :cyan,
    37 => :white,
    40 => :nothing,
    41 => :nothing,
    43 => :nothing,
    44 => :nothing,
    45 => :nothing,
    46 => :nothing,
    47 => :nothing,
  }.each do |key, value|
    if value != :nothing
      data.gsub!(/\e\[#{key}m/,"<span style=\"color:#{value}\">")
    else
      data.gsub!(/\e\[#{key}m/,"<span>")
    end
  end
  data.gsub!(/\e\[0m/,'</span>')
  return data
end

那么,你需要填补我不考虑的颜色或背景的空白.但我想你可以得到这个想法.

希望能帮助到你
