26 Bash Harder With Vim
27 </span>
28 <div class="post-text">
29 <p>Bash is tricky, don&#8217;t let your editor get in your way. Here&#8217;s a couple of neat
30additions you could make to your <code>vimrc</code> for a better shell programming
31experience.</p>
32
33<h3 id="Man%20pages%20inside%20vim">Man pages inside vim</h3>
34
35<p>Source this script to get started: </p>
36
37<pre><code>runtime ftplugin/man.vim
38</code></pre>
39
40<p>Now, you can open manpages inside vim with <code>:Man</code>! It adds nicer syntax highlighting
41and the ability to jump around with <code>Ctrl-]</code> and <code>Ctrl-T</code>.</p>
42
43<p>By default, the manpage is opened in a horizontal split, I prefer using a new tab:</p>
44
45<pre><code>let g:ft_man_open_mode = &#39;tab&#39;
46</code></pre>
47
48<h3 id="Scratchpad%20to%20test%20your%20commands">Scratchpad to test your commands</h3>
49
50<p>I often test my <code>sed</code> substitutions, here is
51a sample from the script used to generate this site: </p>
52
53<pre><code># a substitution to convert snake_case to Title Case With Spaces
54echo &quot;$1&quot; | sed -E -e &quot;s/\..+$//g&quot; -e &quot;s/_(.)/ \u\1/g&quot; -e &quot;s/^(.)/\u\1/g&quot;
55</code></pre>
56
57<p>Instead of dropping into a new shell, just test it out directly from vim!</p>
58
59<ul>
60<li><p>Yank the line into a register:</p>
61
62<pre><code>yy
63</code></pre></li>
64<li><p>Paste it into the command-line window:</p>
65
66<pre><code>q:p
67</code></pre></li>
68<li><p>Make edits as required:</p>
69
70<pre><code>syntax off # previously run commands
71edit index.html # in a buffer!
72w | so %
73!echo &quot;new_post.md&quot; | sed -E -e &quot;s/\..+$//g&quot; --snip--
74^--- note the use of &#39;!&#39;
75</code></pre></li>
76<li><p>Hit enter with the cursor on the line containing your command!</p>
77
78<pre><code>$ vim
79New Post # output
80Press ENTER or type command to continue
81</code></pre></li>
82</ul>
