Hello.
I was debugging my new program when an Java exception was thrown. I'm pretty sure it's not my fault.

Spoiler

1.Create new program

Not a bug, but the error could be better.

You need to escape the brackets in the matching string.


string.gsub("test [[", "%[%[", "test")

See: Programming in Lua, Chapter 20

Yes, I mentioned this.

This'd be something that has to be fixed in LuaJ, though – I'm not sure if Dan can.

A wrapper for the string.gsub function could be made, but it'd get messy.
