<p>this adds a string transformation primarily used for making pretty logs.  for example:</p>

<pre><code>xlog("L_INFO","$var(prefix): $(cs{s.width,7}): $(rm{s.width,9}): request from uac behind nat\n");
</code></pre>

<p>i looked into use <code>$(cs{s.fill.right, " ", 7})</code> but it wasn't meant for that it seems.</p>
