<h1>Module <code>pl.text</code></h1>
<p>Text processing utilities.</p>
<p> This provides a Template class (modeled after the same from the Python
libraries, see string.Template). It also provides similar functions to those
found in the textwrap module.</p>
<p> See <a href="../topics/03-strings.md.html#String_Templates">the Guide</a>.</p>
<p> Calling <code>text.format_operator()</code> overloads the % operator for strings to give Python/Ruby style formated output.
This is extended to also do template-like substitution for map-like data.</p>
<pre><code>> require 'pl.text'.format_operator()
> = '%s = %5.3f' % {'PI',math.pi}
PI = 3.142
> = '$name = $value' % {name='dog',value='Pluto'}
dog = Pluto
</code></pre>
