<a name="range"></a><hr><h3><tt>geany.range ( start, stop [, multi] )</tt></h3>
<p>Returns the text from position <tt><b>start</b></tt> to position <tt><b>stop</b></tt>.<br>
<tt><b>multi</b></tt> is an optional boolean parameter
(<tt><b>true</b></tt> or <tt><b>false</b></tt>, <tt><b>false</b></tt> used by default):
if the position lands inside a multi-byte sequence, <tt><b>geany.range</b></tt>
will use the position at the beginning (<tt><b>start</b></tt>) or
at the end (<tt><b>stop</b></tt>) of that multi-byte character. This is usually
not necessary because GeanyLua functions (<tt><b>geany.caret</b></tt>,
<tt><b>geany.find</b></tt> and so on) and Lua functions (<tt><b>string.find</b></tt> and so on)
use positions in bytes.</p>

<a name="reloadconf"></a><hr><h3><tt>geany.reloadconf ()</tt></h3>
<p>This function will cause Geany to reload most of it's configuration files without restarting
(as menu item <b><i>Tools-><u>R</u>eload Configuration</i></b>).</p>
