Ruby VerboseFormatter.message_for用法及代码示例

返回包含 corrections 的人类可读字符串。这个格式化程序被设计成不那么冗长，不会占用太多的屏幕空间，同时对用户有足够的帮助。

@例子

formatter = DidYouMean::Formatter.new

# displays suggestions in two lines with the leading empty line
puts formatter.message_for(["methods", "method"])

Did you mean?  methods
                method
# => nil

# displays an empty line
puts formatter.message_for([])

# => nil
