emacs + donation

[d paddy]

Greetings...

I was initially pointed to info@fsf.org so as to get help with an emacs
question and donate to fsf.
A consequence of that interaction was my redirection to
help-gnu-emacs@gnu.org...

QUESTION: How do I stop emacs from changing what I type?

EXAMPLE:  I type eleven ascii characters into an empty buffer (in
fundamantal mode) and then save the buffer to the file "example"; the hex
values of those characters are

character 1 : 31
character 2 : 32
character 3 : 33
character 4 : 0a
character 5 : 20
character 6 : 20
character 7 : 20
character 8 : 0a
character 9 : 34
character 10: 35
character 11: 36

Moreover those characters above were typed into the buffer by pressing the
following eleven keys on the keyboard

key 1 :  1
key 2 :  2
key 3 :  3
key 4 :  enter
key 5 :  space
key 6 :  space
key 7 :  space
key 8 :  enter
key 9 :  5
key 10: 6
key 11: 7

The word count utility reports only eight bytes in the file "example" --
even though I typed eleven --  and hexl-mode shows those bytes are

byte 1 : 31
byte 2 : 32
byte 3 : 33
byte 4 : 0a
byte 5 : 0a
byte 6 : 34
byte 7 : 35
byte 8 : 36

Emacs evidently changes my input. How do I cajole emacs into reflecting
exactly what I type?

Many thanks.

P.S. I am not looking for opinions about why I might/should want emacs to
change what I type... I'm looking for the "get-off-my-lawn-mode" wherein
emacs faithfully represents exactly what I type ;-)

Turn off electric-indent-mode.  When that mode is turned on (as it is
by default), typing RET removes trailing whitespace from the previous
line.

Either use C-j instead of enter, or turn off electric-indent-mode
using customize.

I guess you are falling prey to "electric-indent-mode".

(I assume you are using fundamental-mode, but for most programming
modes this is similar)

To check this, re-run your experiment, but *before*, enter the
following command: "M-x electric-indent-mode" (M-x is the META
key, typically Alt on a PC keyboard). You should see the message
"Electric-Indent mode disabled" in the mode line (otherwise my
hunch is incorrect and you may stop reading here :)

Now retry.

You see, electric indent mode inserts spaces to indent a newly
entered line to match the insertion of the line above. To not
let lots of lines with just whitespaces in it, it helpfully
removes trailing whitespace when you leave the line with RET.

Possibly it was this humble minor mode who was stealing the
whitespace you entered.

If you *really* want to have control over non-visible stuff in
your buffer, you might enjoy whitespace-mode, which highlights
(among other things) those otherwise invisible critters.

And now keep those donations coming :-)
