            Bash Harder With Vim
          </span>
          <div class="post-text">
            <p>Bash is tricky, don&#8217;t let your editor get in your way. Here&#8217;s a couple of neat
additions you could make to your <code>vimrc</code> for a better shell programming
experience.</p>

<h3 id="Man%20pages%20inside%20vim">Man pages inside vim</h3>

<p>Source this script to get started:  </p>

<pre><code>runtime ftplugin/man.vim
</code></pre>

<p>Now, you can open manpages inside vim with <code>:Man</code>! It adds nicer syntax highlighting
and the ability to jump around with <code>Ctrl-]</code> and <code>Ctrl-T</code>.</p>

<p>By default, the manpage is opened in a horizontal split, I prefer using a new tab:</p>

<pre><code>let g:ft_man_open_mode = &#39;tab&#39;
</code></pre>

<h3 id="Scratchpad%20to%20test%20your%20commands">Scratchpad to test your commands</h3>

<p>I often test my <code>sed</code> substitutions, here is
a sample from the script used to generate this site:  </p>

<pre><code># a substitution to convert snake_case to Title Case With Spaces
echo &quot;$1&quot; | sed -E -e &quot;s/\..+$//g&quot;  -e &quot;s/_(.)/ \u\1/g&quot; -e &quot;s/^(.)/\u\1/g&quot;
</code></pre>

<p>Instead of dropping into a new shell, just test it out directly from vim!</p>

<ul>
<li><p>Yank the line into a register:</p>

<pre><code>yy
</code></pre></li>
<li><p>Paste it into the command-line window:</p>

<pre><code>q:p
</code></pre></li>
<li><p>Make edits as required:</p>

<pre><code>syntax off            # previously run commands
edit index.html       # in a buffer!
w | so %
!echo &quot;new_post.md&quot; | sed -E -e &quot;s/\..+$//g&quot;  --snip--
^--- note the use of &#39;!&#39;
</code></pre></li>
<li><p>Hit enter with the cursor on the line containing your command!</p>

<pre><code>$ vim
New Post         # output
Press ENTER or type command to continue
</code></pre></li>
</ul>
