pyparsing v2.1.7 Release Notes
Release Date: 2016-08-01 // over 7 years ago-
🛠 Fixed regression reported by Andrea Censi (surfaced in PyContracts tests) when using ParseSyntaxExceptions (raised when using operator '-') with packrat parsing.
Minor fix to oneOf, to accept all iterables, not just space-delimited strings and lists. (If you have a list or set of strings, it is not necessary to concat them using ' '.join to pass them to oneOf, oneOf will accept the list or set or generator directly.)
