Ruby 中带有 html 标签的 ANSI 转义码？

发布于 2024-10-15 20:02:26 字数 309 浏览 3 评论 0原文

有趣的是，Ruby中有内置的ansi转义码。

还有一个来自 a gem 的更强大的版本。

不幸的是，这些日志输出到控制台。我的文本显示在页面中，因此我需要 HTML 标签来包围我的文本。

你们知道如何去做吗？

我猜你想要的是从转义字符转换为 HTML。

我通过假设以下转义字符的代码/颜色哈希来完成一次：

{ :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（远未优化）：

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

嗯，您将需要填充我没有考虑的颜色或背景的间隙。但我想你能明白这个想法。

希望有帮助

I guess what you want is to transform from escape characters to HTML.

I did it once by assuming the following code/colour hash for escape characters:

{ :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}

What I did was the following conversion (far away from being anyhow optimized):

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

Well, you will need fill the gaps of the colours I am not considering or backgrounds. But I guess you can get the idea.

Hope it helps
