I am trying to parse a very long string with cc.strings.require so the wrapped printer can print all parts of the string rather than getting to the end of the line and stopping there. However, when trying to wrap() a variable containing a string, and trying to print the result, the program crashes with "Tried to concatenate global/local "string" (a table value)"

The input is a read(). Sample code would look like

local string = require "cc.string".wrap(read(),10)

Maybe I am doing it wrong, but I am taking this from the documentation (and is also labeled as a use to wrap a string before sending to a printer)

string is a standard API name; using it as a variable name can cause unintended behavior. It looks like you're defining a string variable in one place, but then that gets lost in some way, and when further code tries to print it it prints the string API instead of your string variable. I'd recommend using a different name, such as str.

This is expected behaviour - cc.strings.wrap returns a list of lines, rather than a single string.

I've updated the docs to hopefully make that more obvious. If it's still not clear, do say - I'm not very good at actually explaining how things work :/.
