#apply_inkjet_code!(code, wrap = false) ⇒ Object

Apply a formatting code to the appropriate chunks in the string.

If forcing a wrap, all chunks within the string get formatted with the new code, regardless of whether they were previously formatted

If there are codes applied to the first chunk of the string, apply the new code to all previously formatted chunks with matching codes

If the first chunk of the string is unformatted, apply the new code to all unformatted chunks

If the string is completely unformatted, enclose self within the provided code
