LASS allows you to do that too using the <code>:let</code> directive and by abusing the vector type. It is probably best illustrated using an example:</p> <pre><code>(:let ((foo "#0088EE"))

</code></pre> <p>Once you visit a <code>.lass</code> file, it will automatically start in the <code>LASS</code> major-mode, which is a derived-mode from <code>COMMON-LISP-MODE</code>. Whenever you save, it will automatically try to compile the lass file to its CSS equivalent. If slime is connected, it will try to quickload LASS and evaluate <code><a href="#LASS:GENERATE">GENERATE</a></code>. If slime is not connected, it instead executes a shell command. In order for that to work, the <a href="https://github.com/Shinmera/LASS/releases"><code>lass</code> binary</a> must be in your path.</p> <p>If your operating system is not directly supported with a binary, you can build it yourself using a build tool like <a href="http://www.xach.com/lisp/buildapp/">Buildapp</a>, the ASDF system <code>BINARY-LASS</code> and the entry-point <code>BINARY-LASS:CMD-WRAPPER</code>.</p> <h2>ASDF Integration</h2> <p>If you want to compile LASS files to CSS in your systems, you can now (v0.4+) do this via a <code><a href="#LASS:LASS-FILE">lass-file</a></code> component type, and <code>:defsystem-depends-on</code>-ing LASS.</p> <pre><code>(asdf:defsystem my-system
