In this post, I'll be referring to the actual code in use as linked.
Since the table
tracks is registered as an upvalue already, I'll address a solution to assigning a series of values to it in the function. The way it is set up now, it's going to create a new table every time the function runs. The brackets used to define the table are actually called the Table Constructor and their entire purpose is to build a new table with the values given inserted initially.
What I suggest is to replace line 380 with the following:
Lua Code:
table.wipe(tracks);
for i in string.gmatch(db.profile["Bars"][x][y].track,"[^#]+") do tinsert(tracks,i); end
What this does is runs a pattern-matching iterator to reconstruct the table in the same manner
strsplit() would, reusing the old table instead of creating a new one each time. The pattern string I provided tells it to return chunks of the string that doesn't include the hash (#) symbol.
