This question comes from here: https://github.com/tpope/vim-fugitive/issues/1586
In a word, I'm using the two plugins: Nerdtree and vim-fugitive. What I need is when I execute
:Git checkout mybr, I want to make Nerdtree be refreshed automatically.
So tpope told me that I could use
autocmd User FugitiveChanged.
This is the first time that I see
autocmd User. It seems that
User means "never execute automatically". So I've tried to manually execute this in my vim:
:doautocmd User FugitiveChanged.
However, nothing happend: no error but Nerdtree hasn't be refreshed either.
Did I do something wrong?
