0.5.0

Features

• simplint publishes a JSON Schema of the [tool.simplint] table as simplint.schema.json, which editors use to check the table as the user types. simplint config-schema prints it (#46) by @gaborbernat.
• Types in a public signature count as public API: a class or alias that an exported name's annotations or bases refer to is no longer reported as unused in __all__, and missing-from-all lists it there (#47) by @gaborbernat.
• up-argparse-suggest-on-error (SMP519) flags suggest_on_error=True in argparse.ArgumentParser() calls, which Python 3.15 makes the default, with a safe fix that drops the keyword (#48) by @gaborbernat.
• up-asyncio-iscoroutinefunction (SMP516) flags asyncio.iscoroutinefunction() calls, which inspect.iscoroutinefunction() replaces, with an unsafe fix since the two differ for legacy coroutine markers (#48) by @gaborbernat.
• up-backport-import (SMP305) flags imports of backports the standard library replaced, such as tomli for tomllib on Python 3.11 and later; the tomli and exceptiongroup imports get a fix (#48) by @gaborbernat.
• up-chdir-restore (SMP513) flags a working directory restored in a finally clause, which contextlib.chdir does on Python 3.11 and later, with a safe fix that adds the contextlib import (#48) by @gaborbernat.
• up-codecs-open (SMP517) flags codecs.open() calls, which the builtin open() replaces with newline="" and an encoding, with an unsafe fix since line iteration differs for some separators (#48) by @gaborbernat.
• up-comprehension-unpacking (SMP508) flags a nested for clause that only unpacks its iterable, which Python 3.15 lets the element do with * or **, with a safe fix for lists, sets and generators (#48) by @gaborbernat.
• up-context-var-token-reset (SMP512) flags a ContextVar.set() token that a try block resets in its finally clause, which a with block does on Python 3.14 and later, with a safe fix (#48) by @gaborbernat.
• up-event-loop-in-coroutine (SMP515) flags asyncio.get_event_loop() calls in coroutines, which asyncio.get_running_loop() replaces on Python 3.10 and later, with a safe fix (#48) by @gaborbernat.
• up-exc-info-exception (SMP510) flags sys.exc_info() reads of the exception being handled, which sys.exception() returns directly on Python 3.11 and later, with a safe fix (#48) by @gaborbernat.
• up-lazy-modules-list (SMP307) flags a __lazy_modules__ list whose imports Python 3.15 can spell as lazy import, and fixes both (#48) by @gaborbernat.
• up-object-sentinel (SMP511) flags module and class constants assigned a bare object(), which the Python 3.15 sentinel builtin names, with an unsafe fix since the repr changes (#48) by @gaborbernat.
• up-re-error-alias (SMP518) flags re.error references, which re.PatternError replaces on Python 3.13 and later, with a safe fix (#48) by @gaborbernat.
• up-removed-ast-node (SMP520) flags ast.Num, ast.Str, ast.Bytes, ast.NameConstant and ast.Ellipsis references and visit_ methods that Python 3.14 removed, with safe fixes for the common isinstance and constructor forms (#48) by @gaborbernat.
• up-strptime-date (SMP514) flags datetime.strptime(...).date() and .time() calls, which date.strptime and time.strptime replace on Python 3.14 and later, with a safe fix for dates and for times in literal formats without %z (#48) by @gaborbernat.
• up-traceback-exception-arguments (SMP509) flags traceback calls that pass an exception's type and traceback next to the exception, which Python 3.10 reads from the exception, with a safe fix (#48) by @gaborbernat.
• up-type-checking-lazy-import (SMP306) flags if TYPE_CHECKING: blocks of imports that Python 3.15 can spell as lazy imports, with an unsafe fix (#48) by @gaborbernat.
• up-unittest-assert-helper (SMP811) flags assertTrue and assertFalse on startswith, endswith, hasattr and issubclass checks in TestCase methods, which the Python 3.14 assertStartsWith family replaces (#48) by @gaborbernat.
• up-unittest-enter-context (SMP812) flags a patch that a TestCase method starts and stops by hand, which self.enterContext replaces on Python 3.11 and later (#48) by @gaborbernat.

Bug fixes

• constant-assert (SMP804) no longer offers a fix that writes invalid syntax when the tuple holds a walrus or a starred element: a walrus check gets parentheses, and a tuple with a starred element gets no fix (#47) by @gaborbernat.
• dataclass-kw-only (SMP703) passes the fields of a call in an f-string = debug field by keyword without changing the printed text. The call's source text stays, and its value follows in a plain field (#47) by @gaborbernat.
• definition-before-use (SMP201) no longer reads the bound or default of a type parameter, or the value of a type statement, as a read at import time. A helper that the same function calls is reported again (#47) by @gaborbernat.
• dependency-import-guard (SMP303) counts a submodule of a standard library package, such as asyncio.taskgroups, as shipped only from the version that adds it, using a table generated from CPython's Lib/ trees, so the guard around it is reported on the targets that have it. Its unsafe fix removed an import left unused by the unwrap, such as import string.templatelib checked only for existence, and keeps it now with a noqa suppression. The guards around _zstd, compression.zstd and _curses stay unreported (#47) by @gaborbernat.
• function-docstring (SMP901) reads the functions in a match statement's case bodies, at module and class level, as it already reads those in if and try blocks, so a docstring on an internal one is reported (#47) by @gaborbernat.
• future-annotations (SMP301) no longer reports the import when a class annotation reads a name the class body binds, such as a method named list in def list(self) -> list[str]. Without the import, Python 3.14 and later evaluate that annotation in the class namespace, where list is the method (#47) by @gaborbernat.
• imprecise-annotation (SMP602) now also reports object and Any in the value of a type statement and in the bounds and defaults of type parameters (#47) by @gaborbernat.
• indistinct-error-class (SMP704) no longer reports an exception class that a handler selects through ExceptionGroup.split(...) or .subgroup(...) (#47) by @gaborbernat.
• init-module-content (SMP407) accepts __lazy_modules__ in a public package's __init__.py, which Python 3.15 reads from the module globals to make the package's imports lazy (#47) by @gaborbernat.
• module-attribute-import (SMP304) keeps the lazy keyword when its fix rewrites a lazy import, so the module still loads on first use of a name. Its fix is no longer offered when a parameter, local, comprehension target, match capture or type parameter of the same name would take the bare name, which made make[Item] call a TypeVar (#47) by @gaborbernat.
• module-variable-case (SMP102) no longer renames a name read in a t-string, where the kept text would change. The name is still reported, without a fix. A name read in an f-string = debug field is renamed with the printed text unchanged (#47) by @gaborbernat.
• module-variable-case (SMP102) no longer renames a type alias. The statement binds a type rather than a value, so type vector = list[float] keeps its name (#47) by @gaborbernat.
• module-variable-prefix (SMP404) no longer renames a name read in a t-string, where the kept text would change. The name is still reported, without a fix. A name read in an f-string = debug field is renamed with the printed text unchanged (#47) by @gaborbernat.
• module-variable-prefix (SMP404) no longer asks for a leading underscore on a type alias (#47) by @gaborbernat.
• rst-returns (SMP923) reads a quoted return annotation, such as -> "None" or -> 'NoReturn', as the unquoted form it spells. Before, a quoted None counted as returning a value (#47) by @gaborbernat.
• rst-unknown-attribute (SMP921) accepts a :cvar field that documents a type statement in the class body, and no longer deletes that field (#47) by @gaborbernat.
• single-letter-name (SMP101) now reports a single-letter **rest capture in a mapping pattern, as it already does for *rest in a sequence pattern (#47) by @gaborbernat.
• single-use-variable (SMP504) no longer inlines a variable where the target Python version rejects the result or the meaning changes: a value with a backslash before Python 3.12, a conditional read, an annotation, a type statement, an except type, a match case, or a decorator before Python 3.9. Before Python 3.12, a value whose strings use the f-string's quote takes the other quote in those strings. A variable read in an f-string = debug field is inlined with the printed text unchanged. A value that starts with { gets a space inside its field, so the field does not read as an escaped brace (#47) by @gaborbernat.
• single-user-constant (SMP202) no longer offers a fix for a constant read in a t-string, where inlining or renaming would change the kept text. The constant is still reported. A constant read in an f-string = debug field is inlined or renamed with the printed text unchanged (#47) by @gaborbernat.
• string-concatenation (SMP503) wraps a generator passed bare to str, repr or ascii in parentheses, so its fix no longer writes a syntax error. A name bound by a PEP 695 type parameter is no longer treated as a str, so its chain is reported without a fix (#47) by @gaborbernat.
• test-class (SMP801) offers a fix for a generic class. Each method keeps the class's type parameters that its signature, body or nested type statements use, with their bounds and defaults, so class TestBox[T] becomes def test_box_default[T](...). Defaults need Python 3.13, so below it a method using a defaulted parameter gets no fix (#47) by @gaborbernat.
• undocumented-public-api (SMP903) reports a public type statement that has no docstring, as it does for other public variables. It also reads the public definitions in a match statement's case bodies, at module and class level, as it already reads those in if and try blocks, so they are no longer skipped (#47) by @gaborbernat.
• unexported-public-name (SMP403) no longer renames a name read in a t-string, where the kept text would change. The name is still reported, without a fix. A name read in an f-string = debug field is renamed with the printed text unchanged (#47) by @gaborbernat.
• A fix that adds syntax the file's target Python version does not support is reverted, and simplint reports it as a bug in the fix, as it does for a fix that breaks the syntax (#47) by @gaborbernat.
