If there is nothing to do,
`delete-trailing-whitespace', doesn't do anything.
Also, I have RET `newline-and-indent'. I never thought
about it, but what it does is it removes extra blanks
and breaks the line after the last char instead.
This is also something I can recommend for `C-k':
(defun kill-line-remove-blanks ()
(interactive)
(if (looking-at "[[:space:]]*$")
(let ((end (point-max)))
(delete-blank-lines)
(when (= end (point-max))
(delete-horizontal-space)
(delete-char 1))
(when (and (= (point-min) (point))
(looking-at "[[:space:]\n]") )
(kill-line) ))
(kill-line) ))
It works like this - if we let that the char for full
stop (or "period", i.e. "." ) represent point
position:
Text line which isn't empty 1...
.
Text line which isn't empty 2...
Here, the result of invoking the command will be
Text line which isn't empty 1...
Text line which isn't empty 2...
But here -
Text line which isn't empty 1...
.
(add arbitrarily blank lines here)
Text line which isn't empty 2...
- the result will be:
Text line which isn't empty 1...
.
Text line which isn't empty 2...
Interesting!
