如何让VIM始终显示当前块层次结构？

Question

class Foo
  class Bar
    # many lines
    # many lines
    # many lines
    # many lines
    CURSOR
    # many lines
    # many lines
  end
end

If the line "class Bar" is currently outside of the screen, I'd like to have the current blocks' head still visible. Or, better yet, a hierarchical form like so:

class Foo > class Bar > current method/function

How can I achieve that in VIM?

Answer 1

You can achieve that through plugins, of which I suggest two:

1. tagbar plugin, as already suggested by @Kent.
2. vim-airline plugin with tagbar extension enabled.

This, together with ctags, Vim will always show your current context in the right side of your status line.
