Installation

Use your favorite plugin manager.

Vim

Lazy

require("lazy").setup({

Autocmd

Modify the filetypes as needed. It's better to specify the exact filetypes you want to support. Certain filetypes, like Markdown, require trailing whitespace for specific purposes.

Vim

autocmd BufWritePre *.c *.py *.sh *.vim call CleanTrailingWhitespaceAndTabs()

Neovim

vim.cmd([[
  autocmd BufWritePre *.c,*.py,*.sh,*.vim call CleanTrailingWhitespaceAndTabs()
]])

Shortcut

Vim

nnoremap <Leader>ctws :Ctws<CR>

Neovim

vim.keymap.set("n", "<leader>ctws", vim.cmd.Ctws) -- Ctws [Clean Trailing WhiteSpace]

Why not use :s[ubstitute] ?

Dangerous commands : Avoid using :s[ubstitute] as it moves the cursor and prints error messages. Prefer functions (such as search()) better suited to scripts. For many vim commands, functions exist that do the same thing with fewer side effects. See :help functions() for a list of built-in functions.
