context(context_lines : Int32 | Nil = nil) : Context | Nil

Returns Context record consisting of 3 elements - an array of context lines before the lineno, line at lineno, and an array of context lines after the lineno. In case of failure it returns nil.

Amount of returned context lines is taken from the context_lines argument if given, or configuration.context_lines otherwise.

NOTE: amount of returned context lines might be lower than given in cases where lineno is near the start or the end of the file.
