| | | | | | | | | | | | | | | | | | | * Use Literal.__new__ to select optimized subclasses This turns Literal() into a factory which creates an object of the appropriate type from the start, rather than having to overwrite the __class__ attribute later. * Fix Literal.__copy__() Instance attributes from superclasses weren't being transferred to the copy. Regression test included. * Make Empty a subclass of Literal This unifies the logic with other optimized literal classes like _SingleCharLiteral, and it seemed right in terms of a type relationship. * Style

* fix Sphinx errors/warnings (#410)Devin J. Pohly2022-06-101-6/+8
| | | | | | Two warnings remain from the Hebrew and Devanagari names in pyparsing_unicode, but those are due to Sphinx using Python's builtin `re` library to parse identifiers (which does not have thorough Unicode handling for `\w`).

| | | | | | | | | * Fix list formatting in docstrings A few docstrings were missing a blank line before lists, causing the start of the list to be parsed by RST as a continuation of the previous line. * add backticks to parameter names in lists

* Fix type annotations of Forward dunder-methods (#402)Stephen Rosen2022-05-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix type annotations of Forward dunder-methods The `__lshift__`, `__ilshift__`, and `__or__` methods each return a ParserElement object, but have no annotated return type. The result is that the following code will not type check: def foo() -> pp.ParserElement: expr = pp.Forward() expr <<= bar() return expr | pp.Literal("baz") whereas the code will type check if the return line is changed to return pp.MatchFirst([expr, pp.Literal("baz")]) This is a bug in the types which can be resolved fairly simply with some return type annotations. Testing is more complicated. Testing annotation accuracy is a relatively novel space with a few options, none of which can be considered standard as of yet. Many solutions require learning a new toolchain only for that purpose. However, one of the lower-impact options is to use `mypy --warn-unused-ignores` to check that annotations satisfy some constraints. This isn't the most precise test possible, but it's simple and uses a widely known and familiar tool for the job. `tox -e mypy-tests` is a new tox env which calls `mypy` in the desired way. We can confirm with a new test case file that `tox -e mypy-tests` fails prior to this change to `pyparsing/` and that it passes with the change made. * Comment out mypy-test tox env for CI Until CI adjustments are made, it's not possible to add mypy-test to the tox config. It will be run under pypy where it does not work until other changes are made.
