Hey guys,
I am new to attract mode and I try to get my head around modifying a theme.
First question:
I get a string back from calling a function. Like this...
Local scroller = "[!get_history]";
The string shows ok on screen. It contains the text from history.dat. But if I try something like
Local length = scroller.len();
I always get 14. And when I print the string to console it says "[!get_history]"
It seems like it behaves similar to a magic token.
How do I convert such a string to a real string with real content?
Second question:
How do I remove all line feeds (/n) from a string?
Any help is appreciated!

I had the same problem. I looked it up.... and basically you're right. Those are late parsed, you have to use a callback.
Local scroller = "[!get_history]";
local scroller_length = 0
function history_text_length( tick_time )
{
scroller_length = scroller.len()
return false
}
fe.add_ticks_callback("history_text_length");
