[VIM] Not jumping to half of the screen when scroll to the right (horizontally) in a long line

:set sidescroll=1

Thanks @iporsut for triggered my curiosity

Set bash completion when aliasing docker to d

After you installed docker bash completion, either by sourcing it from your .bash_profile or installing it to bash-completion, add this line to the end of your docker-completion.sh file.

complete -F _docker d

Reload your shell. And that's it!

Note: change the last d to other character you aliased docker to

[VIM] Move screen before cursor reaching top or bottom

It's interesting that I didn't realize I had been living without this feature for years as a vim user. Thanks to @tenderlove and @searls for publishing their vim setup session video. In the beginning of this video, @tenderlove adds set scrolloff=2 to vimrc. scrolloff is a good config that everyone who's using vim should have in their vimrc.

What it does is to tell vim to move screen before cursor reaching 2 top or bottom lines (2 is an arbitrary number). Give it a try. I bet you'll like it.

I went observe on JetBrains' IDE, they are configured to behave the same with setting scrolloff=1 on vim.
