Maybe related, or not:
print(string.format("%s", true))
==>
Error: xyz.lua:192: bad argument #2 to 'format' (string expected, got boolean)
_Sometimes_, in some program files (and the same with other
non-string and non-number types).
(This is why I was so surprised when, in a previous thread, Luiz H.
de Figueiredo just stepped it to note it's right what format now
does in 5.2 (auto-convert to string). I then checked in a test file,
and it worked like a charm. But I knew I had had these errors
precisely, reason of my to wrap that into a printf and worrying.
These same errors now come back in different files of 2 different
projects. And again I have checked I don't modify by error any
builtin func or "type-table".)
Indeed, it seems quite related. Again, it looks like you are using Lua
5.1 instead of Lua 5.2:
Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio
print(string.format("%s", true))
stdin:1: bad argument #2 to 'format' (string expected, got boolean)
Lua 5.2.1 Copyright (C) 1994-2012 Lua.org, PUC-Rio
print(string.format("%s", true))
true
