My plan is to introduce a global options to set various this, also the output format, eg. $ btrfs --format=json subvolume list that would dump the list in json obviously, more formats could follow. This requires to switch all printf to a wrapper that would select the format based on global config. Some of the code is there, eg. the global option parser and the config structure. The printf transitions can be done incrementally. All of that is easy IMHO, somebody just needs to do it. I work on that when there are no other more pressing things to do. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
