Last commit is a little broken for me
Some screenshots to illustrate.
Left side is Sublime3 with latest package, Right side is LDT 1.0 (Koneki Lua Development Tools)
First side by side is my targetAssist addon, second one my TalentSwap addon (here are more obvious issues, a special characters escape pattern I have near the top breaks highlighting for the rest of the file)
But you can also see on the first comparison how LDT does local vs global (local is normal grey, global is bold black)
Off-topic, LDT doesn't have a Wow API highlight package but it does Lua highlighting, code folding, formatting etc better than any editor I've used.
