Bash Harder With Vim
</h1>
<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 = 'tab'</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 "$1" | sed -E -e "s/\..+$//g" -e "s/_(.)/ \u\1/g" -e "s/^(.)/\u\1/g"</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 "new_post.md" | sed -E -e "s/\..+$//g" --snip--
^--- note the use of '!'</code></pre>
<ul>
<li>Hit enter with the cursor on the line containing your command!</li>
</ul>
<pre><code>$ vim
New Post # output
Press ENTER or type command to continue</code></pre>
