Spell checking⚑

Set tabulation⚑

Execute set tabstop=2 shiftwidth=2 expandtab and then, it's a good idea to execute :retab.

Vim saves the "clipboard" history as registers. You can check the saved ones with :reg.

If you want to paste the content of one of them use "3p for example.

Deleting trailing whitespaces automatically⚑

Add the following line to your .vimrc to automatically delete the trailing whitespaces when saving the file if it's one of the specific file types:

autocmd FileType c,cpp,java,php autocmd BufWritePre <buffer> %s/\s\+$//e

Change filetype based on directory path⚑

autocmd BufRead,BufNewFile set syntax=html

(http://vim.wikia.com/wiki/Change_filetype_based_on_directory_path)

Autoindent with tab as 4 spaces⚑

Set in .vimrc the following lines:

CtrlP⚑

CtrlP changes working directory annoyingly⚑

Disable working path mode feature: let g:ctrlp_working_path_mode = '0'

UltiSnips and YouCompleteMe⚑

Since by default they both use as a expand tab, we must do something about it. Using the SuperTab plugin:

```vimrc " make YCM compatible with UltiSnips (using supertab) let g:ycm_key_list_select_completion = let g:ycm_key_list_previous_completion = let g:SuperTabDefaultCompletionType = ''

" better key bindings for UltiSnipsExpandTrigger let g:UltiSnipsExpandTrigger = "" let g:UltiSnipsJumpForwardTrigger = "" let g:UltiSnipsJumpBackwardTrigger = "" ````
