* How to change line endings - where is it explained?

Is it explained in the manuals how to change line endings? I can not 
find it (neither for the lisp level or user level), but that is maybe 
just me.

I had to look up the function mode-line-change-eol to find out how.

Yes, it is described in the node "Text and Binray".

What did you try to look for it?  Perhaps we need to improve the
indexing.

Thanks, yes I wonder why I missed that. A couple of small things perhaps:

- The name of the node is a bit "C style".
- I looked for "line endings".
- I looked for "line end conversion".
- I actually also searched for CRLF, but possibly only in the elisp 
manual since I wanted to do the conversion in code.
- I was thinking about coding systems, but somehow I missed that you 
could use just 'unix or 'dos for the coding system in some operations.
- I looked at the node "(emacs) Files" which says it tells everything 
about files.
- I looked at `buffer-file-coding-system' etc.

I think that I have some difficulties with English here. I however also 
think that the essence of the topic is a bit absent in the manuals. It 
is very an important topic if you are on w32 but not that important if 
all you care about is unix-style platforms.

Some suggestions:

- A link to  "(emacs) Coding Systems"  in "(emacs) Files".
- Something about line endings too in "(emacs) Files", possibly in 
connection with the link above.
- "(emacs) Coding Systems" should mention 'dos, 'unix and 'mac.
- "(elisp) Files" should mention line endings.
- `describe-coding-system' could somehow mention line endings.

Forgot to say that the elisp manual also should say something about how 
to find out the line endings currently used.

I'm not sure I understand what you mean by that.  In particular, what
is the exact meaning of ``currently used''.

I was thinking about the line endings that will be used when writing the 
buffer (with just C-x C-s for example). But I might misunderstand 
something here?

I have not been following this thread, so I may be the one
misunderstanding something, but what about `(elisp)MS-DOS File' or
other sections of `(elisp)Coding Systems'?

Sincerely,

You mean the current buffer's coding-system
(a.k.a. buffer-file-coding-system).

In that case, is coding-system-eol-type what you'd like to be added to
the Lisp manual?

There is already such a link: see the node "Visiting".

Ditto: "Visiting" already talks about EOLs.

It already does, please take a closer look.

I added the references to code and EOL conversions to the appropriate

Done.

the elisp manual.

Oh, I found it! But I did not see it before. The reason is that I am 
nearly always searching, not reading. In "(emacs) Visiting" the term for 
line endings is "convention it uses to separate lines". Could perhaps 
"(line endings)" be added right after this? :

      convention it uses to separate lines (line endings) -- newline

I just checked out a fresh copy from CVS and I am afraid I still can not 
find anything about the use of just 'dos, 'unix and 'mac like in

    M-x set-buffer-file-coding-system RET unix RET

As I understand it this changes just the line endings to unix style 
(LF). Would it not be good to mention this feature?

That is almost certainly not the right way to use the manual.
Searching is a vehicle of getting to the right node, but once you are
already there, you should read it in its entirety.

I actually dislike the term "line endings"; "end-of-line format" is a
better term, IMO.

??? How can that be?  Are we talking about the same thing here?
Here's the fragment I had in mind:

       Each of the listed coding systems has three variants which specify
    exactly what to do for end-of-line conversion:

    `...-unix'
	 Don't do any end-of-line conversion; assume the file uses newline
	 to separate lines.  (This is the convention normally used on Unix
	 and GNU systems.)

    `...-dos'
	 Assume the file uses carriage-return linefeed to separate lines,
	 and do the appropriate conversion.  (This is the convention
	 normally used on Microsoft systems.(2))

    `...-mac'
	 Assume the file uses carriage-return to separate lines, and do the
	 appropriate conversion.  (This is the convention normally used on
	 the Macintosh system.)

       These variant coding systems are omitted from the
    `list-coding-systems' display for brevity, since they are entirely
    predictable.  For example, the coding system `iso-latin-1' has variants
    `iso-latin-1-unix', `iso-latin-1-dos' and `iso-latin-1-mac'.

Ah, you mean this paragraph (from "Text Coding"):

       You can also use this command to specify the end-of-line conversion
    (*note end-of-line conversion: Coding Systems.) for encoding the
    current buffer.  For example, `C-x <RET> f dos <RET>' will cause Emacs
    to save the current buffer's text with DOS-style CRLF line endings.

Maybe it is a little bit a matter of cognitive style? It is really hard 
to organize a big text like Emacs manual and I tend to think that maybe 
I am not in the right node and then I continue searching. Sometimes this 
is the best approach I believe and sometimes not. This time it was 
certainly not the best strategy I was using, you are right in that.

It might well be that most people doing some programming tend to have a 
cognitive style that is more consistent with the reading style you suggest.

If you dislike that term I suppose that there are more native English 
speaking people that does that. But there is one drawback with the term 
"end-of-line format" and that is that there is a function with that 
name. It makes searching a little bit harder, perhaps. However I would 
be glad if one term was use consistently in the manual. That makes my 
way of reading the manual (=searching) quite a bit more easy.

Yes, that is more in line with what I was searching for. And looked for 
in the node "(emacs) Coding Systems".

To summarize: What I would have found most useful would have been one 
consistent term for "line endings"/"end-of-line 
conversions"/"end-of-line type" since this makes searching easier.
