My fault. I briefly thought that it may be simpler to treat %(color) just as a different way to express a literal that cannot be typed from the keyboard, but your "different kind of atom" is a much better way to think about it. What is necessary is that, just like the updated "print_value()" knows about the formatting state, "emit()" needs to be told about the same formatting state. Some of these "state affecting" atoms may take effect on what is output by "emit()" (e.g. "color" is obviously an example, the hypotethical one that counts the current output column and uses that knowledge to "align" the output to certain columns, instead of "right pad to make the next column 30-columns wide" one, which is in this series, is another). Thanks for finding this, and Karthik, sorry for an incomplete suggestion based on a faulty thinking. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
