Bug:
When trying to string,find for [[ , it will give you:
Lua:1: vm error: java.lang.arrayIndexOutOfBoundsException: 2
What I did:
f=string.find("[[]]","[[")
It happens any time you search for [[ , though. Screenies aren't really necessary here.
edit: also, it happens if you search for "=[[". It gives the same error, but a 3 rather than 2
doubleedit: no, it errors any time you find "[" using string.find in a string.

Looking at string patterns, you can see that [ and ] serve a similar purpose to that in regexes.

You can pass an optional 4th argument to string.find which is plain. So you would want to have:

-- Find [[ in [[]] from position 1, without using Lua patterns
string.find("[[]]", "[[", 1, true)

This isn't a bug and is the correct behaviour for Lua.

You can also prefix the symbol with a percent sign if you prefer.

string.find("[[]]", "%[%[")

Oh. Thank you.
