            Bash Harder With Vim

          <div class="post-text">
            <p>Bash is tricky, don’t let your editor get in your way. Here’s a
couple of neat additions you could make to your <code>vimrc</code> for a
better shell programming experience.</p>
<h3 id="man-pages-inside-vim">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-to-test-your-commands">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>Yank the line into a register:</li>
</ul>
<pre><code>yy</code></pre>
<ul>
<li>Paste it into the command-line window:</li>
</ul>
<pre><code>q:p</code></pre>
<ul>
<li>Make edits as required:</li>
</ul>
<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/\..+$//g&quot;  --snip--
^--- note the use of &#39;!&#39;</code></pre>
<ul>
<li>Hit enter with the cursor on the line containing your command!</li>
</ul>
<pre><code>$ vim
New Post         # output
Press ENTER or type command to continue</code></pre>
