- Update to version 1.5.6:
* Cleanup of parse action normalizing code, to be more version-tolerant,
and robust in the face of future Python versions
* Removal of exception cacheing, addressing a memory leak condition
in Python 3.
* Fixed bug when using packrat parsing, where a previously parsed
expression would duplicate subsequent tokens
* Fixed bug in srange, which accepted escaped hex characters of the
form '\0x##', but should be '\x##'. Both forms will be supported
for backwards compatibility.
* Added the Verilog parser to the provided set of examples, under the
MIT license.
* Added the excludeChars argument to the Word class, to simplify defining
a word composed of all characters in a large range except for one or two.
* Added optional overlap parameter to scanString, to return overlapping
matches found in the source text.
* Updated oneOf internal regular expression generation, with improved
parse time performance.
* Slight performance improvement in transformString, removing empty
strings from the list of string fragments built while scanning the
source text, before calling ''.join. Especially useful when using
transformString to strip out selected text.
* Enhanced form of using the "expr('name')" style of results naming,
in lieu of calling setResultsName. If name ends with an '*', then
this is equivalent to expr.setResultsName('name',listAllMatches=True).
* Fixed up internal list flattener to use iteration instead of recursion,
to avoid stack overflow when transforming large files.
- Changes from version 1.5.5:
* Typo in Python3 version of pyparsing, "builtin" should be "builtins".
- Changes from version 1.5.4:
