title: 'VIM-Shell: Why Hasn''t Vim Had This All Along?'
---
<p>I stumbled across <a href="http://www.wana.at/vimshell/" title="Best Vim extension ever.">VIM-Shell</a> completely on accident. it's a patch
against <a href="http://www.vim.org/">Vim</a> that does exactly what it sounds like; adds
rudimentary shell support to Vim. Check it out:</p>
<table border='0'>
<tr><td>
<a href='http://pablotron.org/gallery/misc/vimshell.png'><img
src='http://pablotron.org/gallery/misc/vimshell-thumb.png'
width='320' height='200' border='0' style='border: 1px solid black;'
title='Vim with a bunch of shell apps.'
alt='Vim with a bunch of shell apps.' /></a>
</td></tr><tr><td style='text-align: center; font-size: 80%; font-weight: bold;'>
VIM-Shell with a bunch of apps (1680x1050 <acronym title='Portable Network Graphics Image File'>PNG</acronym>).
</td></tr></table>
<p>The default patch kind of blows, so I cleaned it up and fixed a couple
bugs (namely, the <a href="http://www.wogri.at/pipermail/vimshell/2005-January/000089.html" title="Description of the VIM-Shell red terminal bug.">red terminal o' death</a> bug reported on the
<a href="http://www.wogri.at/pipermail/vimshell/" title="The VIM-Shell mailing list.">mailing list</a>). I've submitted the my fixes upstream, but they
haven't been incorperated into the official version yet. In the mean
time, you can get my improved patch by following the link below.</p>
<p><a href="http://pablotron.org/files/vim-7.0.72-vimshell-pabs-1.diff.gz" title="My improved VIM-Shell patch against Vim 7.">Download vim-7.0.72-vimshell-pabs-1.diff.gz</a> (<a href="http://pablotron.org/files/vim-7.0.72-vimshell-pabs-1.diff.gz.asc" title="OpenPGP signature for my improved VIM-Shell patch against Vim 7.">Signature</a>)</p>
<p><em>Note:</em> If you compile it under Linux, you'll need to add a link to
<code>libutil</code>, either via <code>configure</code> or <code>make</code>, like so:</p>
<blockquote>
<p><code>$ ./configure LDFLAGS=-lutil</code></p>
</blockquote>
<p>or</p>
<blockquote>
<p><code>$ make LDFLAGS=-lutil</code></p>
</blockquote>
<p>If you don't, you'll get an undefined reference to <code>forkpty()</code>. I
believe this is a problem with the original patch as well. Now that
you're all excited, here's what VIM-Shell still needs:</p>
<ul>
<li>Slightly better color emulation. Occasionally things seem to "bleed".</li>
<li>Session support. I use sessions pretty regularly, and it'd be nice to
at least restore a blank shell. Even better would be pwd and history.</li>
<li>A way to send a literal <code>Ctrl-W</code> to the shell. Lots of apps use <code>^W</code>,
including Vim and Bash, so not having it is kind of annoying. Maybe a
<a href="http://www.gnu.org/software/screen/">Screen</a>-style escape like <code>^Ww</code>?</li>
</ul>
<p>Even with all these relatively minor gotchas, VIM-Shell is still damn
cool.</p>
