<h1>
Hold Position!
</h1>
<div class="post-text">
<p>Often times, when I run a vim command that makes “big” changes to a
file (a macro or a <code>:vimgrep</code> command) I lose my original
position and feel disoriented.</p>
<p><em>Save position with <code>winsaveview()</code>!</em></p>
<p>The <code>winsaveview()</code> command returns a
<code>Dictionary</code> that contains information about the view of the
current window. This includes the cursor line number, cursor coloumn,
the top most line in the window and a couple of other values, none of
which concern us.</p>
<p>Before running our command (one that jumps around the buffer, a lot),
we save our view, and restore it once its done, with
<code>winrestview</code>.</p>
<pre><code>let view = winsaveview()
s/\s\+$//gc " find and (confirm) replace trailing blanks
winrestview(view) " restore our original view!</code></pre>
<p>It might seem a little overkill in the above example, just use ``
(double backticks) instead, but it comes in handy when you run your file
through heavier filtering.</p>
