whitespace - How to delete <tabsize> spaces when pressing backspace in emacs? -

I have a mode ( vala-mode ) whose default tab is to use No, I want to contribute in the case of projects for which I want to contribute.

So I have set indent-tabs-mode to zero and it works just fine.

But now removes space-by-space by pressing backspace at the end of an indentation; Is there any way to set this tab-width

postprop = back-delete-char- Type "text">

bind DEL to backward-delete instead of untabify .

For example, to replace each other globally, for all its key bindings:

  (define-key [remap-backward-delete- Char-untabify] '' Back-to-Char global-map) or just bind  backward-delete-char  to  DEL  Or any other key in special mode. 
 
 Try to see it, to see if you really like that behavior. Most users do not.
