If somebody that don´t need "Phyton" functionality of Notepad++ is interesed, just in "functionList.xml" document in Notepad++ directory find similar text to the text above and replace with them:
<parser
id ="python_function"
displayName="Python class"
commentExpr="(?s:'''.*?''')|(?m-s:#.*?$)"
>
<classRange
mainExpr ="(?<=^class\x20).*?(?=\n\S|\Z)"
>
<className>
<nameExpr expr="\w+(?=[\(|:])" />
</className>
<function
mainExpr="(?<=func\x20).+?(?=:)"
>
<functionName>
<funcNameExpr expr=".*" />
</functionName>
</function>
</classRange>
<function
mainExpr="(?<=func\x20).+?(?=:)"
>
<functionName>
<nameExpr expr=".*" />
</functionName>
</function>
</parser>
And voilá, you can see your gdscipt functions listed by chosing "Phyton"... (but lost "def" phyton functions). This, combined with adding to config-phyton-KEYWORDS (sorry, don´t have the route, my notepad is in spanish) the words extends, export, null, true, false, onready, signal, etc.... make notepad a very good complement to GODOT. Scripts with more than thousands of lines become very manejable with this.... :wink:
