Hold Position!
</span>
<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>
