Hi all,
Quick tip I’d like to share - every now and then I accidentally add a
space on the end of lines of code.
You can highlight this occurring in vim by adding the following to your
.vimrc file:
highlight ExtraWhitespace ctermbg=red guibg=red
match ExtraWhitespace /\s\+$/
Probably most vi/vim users know this, but to remove newlines, you can use
the following:
:%s/ \+$//g
You could also run that :substitute on :w and never have to worry about
trailing whitespace ever again :)
autocmd BufWritePre * :%s/\s\+$//e
Change the asterisk to any pattern matching filenames to apply this to
certain filetypes only. (Also note the use of \s to match any whitespace
character.)

Happy Vimming!
