Look at this:\n#         for content, style in tokens:\n#             append_text(content)\n#             if style:\n#                 append_span(_Span(offset, offset + len(content), style))\n#             offset += len(content)\n# \n# If 'style' is an empty string, 'if style:' will be false.\n# But if 'style' is provided as an empty string, should it still be a span?\n# Probably not.\n# \n# What if 'tokens' is a list of strings instead of list of tuples?\n# Then 'for content, style in tokens:' will raise ValueError: too many values to unpack (expected 2).\n# \n# Let's try to see if there is any test case in the repo that exercises append_tokens.\n( grep -rn 'append_tokens' --include=*.py tests/ || echo '<IMPORTANT> NO MATCH FOUND.
