This recipe DOES NOTHING!
It is only translation library.
If you not making LUA scripts by yourself it is USELESS for you!

Works great, except for the replace_ss(ss) function. I always get an error at the line that says structure.SetSecondaryStructure(i, ss). The error is
bad argument #2 to 'SetSecondaryStructure' (string expected, got nil)

I also got this error when i attempted to make an all loops function for one of my own scripts, so i don't know what the problem could be...

ss code you want change to.

select_index(x)
replace_ss("L")

or use new code instead, like

for i=ss,se do
structure.SetSecondaryStructure(i,"L")
end

This library is temporary solution anyway :)

Yeah, as I was afraid of.
Those functions, which have just another name but the same number (and order) of parameters, renaming is simple.
It get's tricky if there are more parameters.

I also considered using this library, but this does lengthen the code, so I rather replace it.

But nice workaround, thanks for your work!
