how to control the position of new buffer in vim

Question

I write a vim plugin to get the weather info in python, I use print to print weather info, all core code are wrapped in a function Weather() . when I call this function in vim, the weather info will be showed in a new buffer under current buffer, can I control this new buffer in the left of current buffer or any other position.

Answer 1

If you plan to publish this plugin, you should honor the user's preferences (eg the 'splitbelow' setting), and offer a configuration variable to influence the window placement.

Generally, there are prefix commands that influence the window placement: :vertical , :leftabove , :rightbelow , :topleft , :botright . They are used like this:

:topleft new

Sometimes, it may also be necessary to first go to a particular window, :execute winnr . 'wincmd w' :execute winnr . 'wincmd w' can do this. And finally, many commands that split a new window can be passed an initial window height.
