<div class="textblock"><p>First of all, you don't have to know Scheme language to create theme files. This files use simplified statements to declare variables and set their values.</p>
<p>One statement you already seen is: </p>
<div class="fragment"><pre class="fragment">(theme.name <span class="stringliteral">"Foo"</span>)
</pre></div><p>This will, as you guess, set theme name. Here, <em>theme</em> is a namespace and <em>name</em> is expression that sets internal theme name. Every public Theme expressions has a <em>theme</em> prefix, like <em>(theme.print)</em> or <em>(theme.style)</em>.</p>
<p>You also learned how to assign some value. In common languages (or configuration files), you often would assign variable like this: </p>
<div class="fragment"><pre class="fragment">var = value
</pre></div><p>in Theme language it will be like this: </p>
<div class="fragment"><pre class="fragment">(var value)
</pre></div><p>But, beware! You can't use this assignment syntax all over .ewt files; it is valid only in <em>(theme.style)</em> block.</p>
<p>...which brings us to <em>(theme.style)</em> syntax... Each <em>(theme.style)</em> must have a style name and block with a list of variables and their values. For example: </p>
<div class="fragment"><pre class="fragment">(theme.style <span class="stringliteral">"demo-style"</span> [
var1 <span class="stringliteral">"value1"</span>
var2 <span class="stringliteral">"value2"</span>
])
</pre></div><p>implements <em>var1</em> and <em>var2</em> in "demo-style" style. Each style block begins with <b>[</b> and ends with <b>]</b>. Actually it ends with <b>])</b> because "theme.style" starts with <b>(</b>. This is very similar to syntax used to assign values.</p>
