Q3 - how to delete by words, not cut?

[Tatsu Takamaro]

Question 3 of 4.

What if I want not to cut (or how you call it - kill) a word with 
"backward-kill-word" and "kill-word", but delete it (so as not to put 
the words into the exchange buffer (clipboard))?

                     ^^^^^^^^^^^^^^^
                            ^
                       kill buffer

Something like this:

(defun my-backward-delete-word (arg)
  "Delete backard ARG words.
ARG is the numeric prefix arg (default 1)."
  (interactive "p")
  (let ((opt  (point)))
    (backward-word arg)
    (delete-region opt (point))))

Bind it to some key.

Unfortunately, as it was said by others, there is no built-in function 
to delete by word.

Do you need one?  What's wrong with the non-built-in
one I gave you?

This might give you a hint: Most Emacs users haven't
felt the need for one to be built-in.  Emacs is > 40
years old.  It's had thousands, probably millions, of
users.  And users don't hesitate to request things
they find missing.  You can bet that if it were felt
important that such a function be built-in, it would be.

Well, if I often work with a buffer (I mean a clipboard, not a Emacs's 
buffer), I often paste from it. And with "cut" functions instead of 
"delete" I will have my clipboard full of trash instead of some useful 
text paragraph. Of course, it's not very important.

I assume I would do it by a cycle - delete one char per each iteration 
until the char is a space. But I don't know Elisp, so I'm not sure (for 
now) how to make this cycle and how to bind a cycle (not a single 
command) on a key. So, maybe later. Or maybe someone would help here.

Do what?  Delete a word backwards?  Did you try the
`my-backward-delete-word' command I defined for you?

> But I don't know Elisp...

Time to learn a little, if you want to define your
own commands.  I recommend you look into the Intro
Elisp manual: `C-h i m intro TAB RET'.

The command I defined saves the current cursor
location (point); then it uses predefined function
`backward-word', to move backward a word; then it
uses predefined function `delete-region', to delete
the text between the new location (point) and the
original (saved) location.

If you want to define deletion (not kill) commands,
then use `delete-region' (or other deletion functions).
They're building-block functions, not commands.

I use M-d to delete by word.

The default binding of `M-d' is `kill-word'.
TT wants to delete words without adding them
to the kill-ring.  And backward (like
`backard-kill-word', without killing).

M-Backspace deletes word backword.

What one can do to avoid kill ring is to set variable `kill-ring-max'
to zero with {M-x customize-option RET kill-ring-max} and then it will
not be saved in the kill ring. That is not accurate result for the
wish though. Undo works well, but kill ring becomes empty.

People then press M-y (yank-pop) to go to next "saved" item
