胭脂宝石未在格式化代码中显示换行符? [英] Rouge gem not showing line breaks in formatted code?

问题描述

我遵循了使用 rouge gem

到

 需要胭脂"来源="def plus_two(x)\ n x + 2 \ nend"formatter = Rouge :: Formatters :: HTML.newformatter = Rouge :: Formatters :: HTMLLinewise.new(formatter，类:'line-％i')lexer =胭脂::: Lexers :: R.new@code = formatter.format(lexer.lex(源))

I have followed minimal examples using the rouge gem here (i.e. the documentation), as well as here and here.

Everything working, except that line breaks in the code aren't appearing.

To be explicit, code like this

def plus_two(x)
  x + 2
end

has the colours highlighted correctly, but is rendered across one line, like so

def plus_two(x) x + 2 end 

How can I make it render with the line breaks (just as in the code file)

解决方案

Change

require 'rouge'
source = "def plus_two(x)\n  x + 2\nend"
formatter = Rouge::Formatters::HTML.new
lexer = Rouge::Lexers::R.new
@code = formatter.format(lexer.lex(source)) 

to

require 'rouge'
source = "def plus_two(x)\n  x + 2\nend"
formatter = Rouge::Formatters::HTML.new
formatter = Rouge::Formatters::HTMLLinewise.new(formatter, class: 'line-%i')
lexer = Rouge::Lexers::R.new
@code = formatter.format(lexer.lex(source))
