I'm a bit late to the party, but if you don't mind installing a package then smooth-scrolling (<a href="https://github.com/aspiers/smooth-scrolling" rel="noreferrer">github</a>, also available in <a href="http://melpa.org/#/smooth-scrolling" rel="noreferrer">MELPA</a>) may be what you're looking for - it certainly works for me.

Once you've installed it you can pop the following in your init.el:

<pre><code>(require 'smooth-scrolling)
(smooth-scrolling-mode 1)
(setq smooth-scroll-margin 5)
</code></pre>

The last line is optional; it starts scrolling near the screen edge rather than at it, so you've always got a little context around the point. Adjust to taste.

My solution is not to change Emac's default scrolling, but rather to create a key sequence command from a macro. This way you have a convenient way to scroll one line at a time when you want. Not ideal, but super easy. It just happens that M-(↓) and M-(↑) are available, so that's what I used.

This is how I did it. First, you need to record a macro for one line scrolls, up and down.

Begin macro

<pre><code>C-x ( 
</code></pre>

Scroll down one

<pre><code>C-u 1 C-v
</code></pre>

Stop macro

<pre><code>C-x )
</code></pre>

For scroll up one, use

<pre><code>C-u 1 M-v
</code></pre>

Next you need to name the macro.

<pre><code>M-x name-last-kbd-macro
</code></pre>

Give it a name when prompted like:

<pre><code>down-one-line
</code></pre>

Then just use the following to bind a key sequence to that command name:

<pre><code>M-x global-set-key
</code></pre>

And upon prompting, use something like:

<pre><code>M-(down arrow)
</code></pre>

Then it will ask you which command you want to bind, and you should give it the name you invented earlier, e.g., down-one-line.

Here is where I got this information. You can also find instructions below and elsewhere about adding your macro to the .emacs file.

I've been using these in my <code>.emacs</code> file since 2000.

<pre><code>(global-set-key (quote [M-down]) (quote View-scroll-line-forward))
(global-set-key (quote [M-up]) (quote View-scroll-line-backward)) 
</code></pre>

This way, I can keep the Emacs default behavior as well as scroll one line at a time, depending on what I'm doing.

This worked till at least GNU Emacs 22. I recently upgraded to Emacs 24 and discovered that <code>View-scroll-line-forward</code> and <code>View-scroll-line-backward</code> are no longer available. After some hunting, I discovered that scroll-up-line and scroll-down-line work. So if you're using Emacs 24, you can use this.

<pre><code>(global-set-key (quote [M-down]) (quote scroll-up-line))
(global-set-key (quote [M-up]) (quote scroll-down-line)) 
</code></pre>

I mostly skipped Emacs 23, so if that is the version you're using, you can experiment with both the above.

Note: <code>scroll-up-line</code> actually scrolls one line down, because the buffer is being moved one line up.

 maximum-scroll-margin 0.0
 scroll-up-aggressively 0.0

I believe the values for <code>scroll-margin</code> and <code>scroll-conservatively</code> do not matter much because the <code>maximum-scroll-margin</code> clamps them down. They just need to be equal (maybe?).
Scroll happens line by line, even on the end of the file (worst case for me). The only missing feature was that with this the margin on top and bottom are lost.
Its a compromise and, for me, smooth scrolling is worth it.

To put it simply, I'm trying to get scrolling in emacs like in vim and most other editors; when I'm for example, two lines from the bottom/top, and I press down/up (<kbd>Ctrl</kbd>-<kbd>p</kbd>,<kbd>n</kbd>, <kbd>↑</kbd>,<kbd>↓</kbd>) it goes only one line up or down, not half the screen.

How to scroll line by line in GNU Emacs?

 简单地说，我正在尝试像vim和大多数其他编辑器一样在emacs中滚动；例如，当我在底部/顶部两行时，我按向下/向上(Ctrl-p，n，↑，↓)，它只向上或向下移动一行，而不是半个屏幕。
