How to replace tab's indent by space's indent with web-mode in Emacs I don't want to use tabs for indent, so I add `(setq-default indent-tabs-mode nil)` in my emacs init file. With the setting indents are created by spaces in `web-mode`, but it doesn't change already existing tabs to spaces. Is there a config like `overwrite-tab-indent-by-space-indent`? Or must I replace tabs to spaces by command every time I encounter tab-indented HTML?

To untabify the whole buffer upon opening a file that uses web-mode, you could add something like this to your init file:


(add-hook 'web-mode-hook
(lambda () (untabify (point-min) (point-max))))


This assumes that `web-mode` is the name of the mode you want this setting to apply to; adjust to taste.
