[英]How do I create a paragraph in Ruby?
我正在遍历一个教程,即使我完全按照指示键入了此代码,但又返回了语法错误。 谁能解释如何在ruby中创建一个段落?
我的尝试如下所示。
谢谢
Puts <<PARAGRAPH
There's something going on here.
With the PARAGRAPH thing.
We'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.
PARAGRAPH
你有Puts
。 你想要puts
。
在原来的教程有puts
,而不是Puts
:
# Here's some new strange stuff, remember type it exactly.
days = "Mon Tue Wed Thu Fri Sat Sun"
months = "Jan\nFeb\nMar\nApr\nMay\nJun\nJul\nAug"
puts "Here are the days: ", days
puts "Here are the months: ", months
puts <<PARAGRAPH
There's something going on here.
With the PARAGRAPH thing
We'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.
PARAGRAPH
像一些人说,分配"Here are the days: ", days
要puts
是你的问题。 当您击入puts <<PARAGRAPH
,解释器会尝试将PARAGRAPH
追加到数组puts
而不是生成here doc,但是当然PARAGRAPH
是未定义的。
注意到您实际上仍然可以强制它与语法一起使用是一种有趣的(尽管不是超级有用)
puts(<<PARAGRAPH)
Theres something going on here.
With the paragraph thing.
Well be able to type as much as we like.
Even four lines.
PARAGRAPH
您可以在这里做有趣的事情。 您可以这样做:
<<PARAGRAPH
typing lines of data, etc
more input
PARAGRAPH
或您选择的“任何”大写单词:
<<BUILDING
typing lines, etc
BUILDING
我用过的每个字都有效。
检查PARAGRAPH末尾是否有空格。 确保在PARAGRAPH之后没有空格,您可以走了。
puts <<PARAGRAPH
There's something going on here.
With the PARAGRAPH thing.
We'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.
PARAGRAPH
