I guess if you can have multiple arguments after ':' in an atom, then you have wiggle room for future. But it looks like you only accept one argument after ':'.. (I only checked the version on 'pu'). Having an "alignment atom" to augment the real one (like %< changes the behavior of the next placeholder), could also work, but it adds dependency between atoms, something I don't think ref-filter.c is ready for. Another thing, the atom value is also used for sorting. When used for sorting, I think these padding spaces should not be generated or it may confuse the sort algorithm. Left alignment may be ok, right or center alignment (in future?), not so much. Perhaps we should do the padding in a separate phase, outside populate_value(). If you go this route, having separate atoms for alignment works better: you don't have to parse them in populate_value() which is for actual values, and you can handle dependency easily (I think). By the way, please consider adding _() back to translatable strings, usually those die() or warn(), or "[ahead %s]"... In the last case, because you don't really know how long the string is after translation, avoid hard coding buffer size (to 40). -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
