    When we need to do process some value, or do some text formatting, we can define a filter function, which is really handy. However when I ran into this article about Context processors,:
     I really want to know the differences between a filter function and a context processor function. Is  context processor function mainly designed for those who are not using Jinja, so that they can still implement filters in another way?  I found that people tend to do more complicated things in a context processor function, say get hottest articles in a blog, list recent articles and so on.
