In version 2.1.0 of pyparsing, I fixed a long-standing problem in ParseResults.asDict, which did only the shallowest of conversions of pyparsing’s ParseResults objects to nested lists and dicts. In this case, the ‘ref_path’ element of ‘value’ used to be a ParseResults, which the developer is converting to a list using asList(). With my change in pyparsing 2.1.0, ref_path is now being converted to a list as part of the improved behavior of asDict(). Unfortunately, this code then tries to call ‘asList()’ on that list, which of course, is an error.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The fix is to change this code in rstlib to just:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New";color:black'> value = tokin[0].asDict()<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New";color:black'> ref_path = value.get('ref_path')<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New";color:black'> if ref_path is not None:<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New";color:black'> ref_path = " ".join(ref_path)<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal>This change is actually compatible with the old version of pyparsing as well (since ParseResults also implements list-like iterator behavior).
