Julia 0.3中Docile.jl的示例用法

我是朱莉娅的新手。我对使用添加文档到现有项目感兴趣。根据，Docstring已经添加到Julia 0.4中，但我想让Docstring在0.3中工作

不过，上面文章中的示例在0.3中不起作用<代码>帮助（f）不显示文档字符串，

@doc f

返回错误。有人能帮我看看少了什么吗

您可能希望结合使用Docile.jl。下面的会话显示，如果您只记录函数而不使用Lexicon，则任何函数的帮助文本都不会更改。帮助文本仅在您使用Lexicon键入

后反映您的文档。请注意，在下面，我是通过在repl中键入一个
？
来获取帮助文本的，而不是通过使用函数
help
