| 20 | <p>Often times, when I run a vim command that makes “big” changes to a file (a | ||
| 21 | macro or a <code>:vimgrep</code> command) I lose my original position and feel disoriented.</p> | ||
| 22 | |||
| 23 | <p><em>Save position with <code>winsaveview()</code>!</em></p> | ||
| 24 | |||
| 25 | <p>The <code>winsaveview()</code> command returns a <code>Dictionary</code> that contains information | ||
| 26 | about the view of the current window. This includes the cursor line number, | ||
| 27 | cursor coloumn, the top most line in the window and a couple of other values, | ||
| 28 | none of which concern us.</p> | ||
| 29 | |||
| 30 | <p>Before running our command (one that jumps around the buffer, a lot), we save | ||
| 31 | our view, and restore it once its done, with <code>winrestview</code>.</p> | ||
| 32 | |||
| 33 | <pre><code>let view = winsaveview() | ||
| 34 | s/\s\+$//gc " find and (confirm) replace trailing blanks | ||
| 35 | winrestview(view) " restore our original view! | ||
| 36 | </code></pre> | ||
| 37 | |||
| 38 | <p>It might seem a little overkill in the above example, just use “ (double | ||
| 39 | backticks) instead, but it comes in handy when you run your file through | ||
| 40 | heavier filtering.</p> | ||
