---------------------------------------------------------------------------
-- Showing Markers' Notes on screen
-- by AnS, 2012
---------------------------------------------------------------------------
-- Showcases following functions:
-- * taseditor.getmarker()
-- * taseditor.getnote()
-- * taseditor.getselection()
---------------------------------------------------------------------------
-- Usage:
-- Run the script, unpause emulation (or simply Frame Advance once).
-- Now you can observe Marker Notes not only in TAS Editor window,
-- but also in FCEUX main screen.
-- This script automatically divides long Notes into several lines of text
---------------------------------------------------------------------------
-- Custom function for word-wrapping long lines of text

-- Find last spacebar within first max_num_chars of text
last_spacebar = string.find(string.reverse(string.sub(text, 1, max_num_chars)), " ");
if (last_spacebar ~= nil) then
-- Output substring up to the spacebar
substring_len = max_num_chars - last_spacebar;
else
-- No spacebar found within first max_num_chars of the string
-- output substring up to the first spacebar (this substring will have length > max_num_chars)
substring_len = string.find(text, " ");

-- No spacebars found at all, output whole string
substring_len = string.len(text);
