I know that it is possible: I googled it some time ago, but now I can't find the solution.
What do I need add to
.vimrc to resize my current active window in full height automatically after window changing?
You can do it with an auto command, filtering the
autocmd WinEnter * resize
resize without argument expand the height to max.
If I understand what you mean by window, this should do it.
set winheight=999 set winminheight=0
:help 'winheight' :help 'winminheight'
