Deprecate `locatedExpr` in favor of new `Located` class

Add IndentedBlock class; made vertical keyword arg more visible when creating railroad diags; changed create_diagram from monkeypatch to included method on ParserElement; better debug exception if Dict is constructed with non-Group expression

ParseResults.List class to support returning an actual list from a parse action, plus aslist and asdict args to Group and Dict classes to emit native Python types instead of ParseResults; also update repr() output of ParseResults to include the type name instead of just a bare tuple.

Issue #244, fixed debug output to indicate correct parse location; updated setDebug output to include current text line and parse location

2020-10-12T04:24:20+00:00

Fixed bugs in Each with ZeroOrMore and OneOrMore (first matched element enclosed in extra nesting level; results names not maintained; did not handle mix with required expressions)

2020-10-11T19:21:09+00:00

Convert SyntaxWarnings to ValueError and TypeError exceptions; change diagnostics to an enum, and add enable_diag(), disable_diag() and enable_all_warnings() methods; clean up pyparsing imports in test_unit.py

2020-08-20T03:42:25+00:00

Add '*' markers to debug output to indicate cached parse expression try/pass/fail events (which were previously omitted from debugging output)
