paul j3 added the comment: This is a HelpFormatter function that takes a list of formatted actions, and groups contiguous blocks of optional positional actions. It accounts for optionals (via prefix_chars) and mutually exclusive groups.
Since it assumes 'parts' is a list, rather than string, it works best with the '_format_actions_usage' method in the patch that I submitted to http://bugs.python.org/issue11874 def _positionals_regroup(self, parts): # change '[arg1] [arg2]' to '[arg1 [arg2]]' # apply to a list of formatted arguments # don't apply to optionals (with prefix chars) or groups chars = getattr(self, 'prefix_chars',set('-')) R = _re.compile(r'\] \[(.*)\]') result = [] text = None while parts: part = parts.pop() if part: if part[0]=='[' and part[1] not in chars and '|' not in part: if text: text = ' '.join([part, text]) else: text = part if R.search(text): text = R.sub(' [\g<1>]]',text) else: if text: result.insert(0,text) text = None result.insert(0,part) if text: result.insert(0,text) return result To avoid compatibility issues it could implemented in a subclassed HelpFormatter. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11708> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
