Start vim on a folder vim .

[dadaphl]

I would like vim to display a full-window of chadtree automatically when opening vim with a folder as argument (vim .) or opening a folder from within vim (:e .). I'm used to this behavior form NERDTree

Without chadtree
vim .

With NERDTree
vim .

Try adding the following to your .vimrc as it worked for me

autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 1 && isdirectory(argv()[0]) && !exists('s:std_in') |
    \ execute 'CHADopen' | execute 'cd '.argv()[0] | endif

Thank you very much! That solves the issue for me.
