-# Breaking Changes
-
-## 0.0.288
-
-### Remove support for emoji identifiers ([#7212](https://github.com/astral-sh/ruff/pull/7212))
-
-Previously, Ruff supported the non-standard compliant emoji identifiers e.g. `📦 = 1`.
-We decided to remove this non-standard language extension, and Ruff now reports syntax errors for emoji identifiers in your code, the same as CPython.
-
-### Improved GitLab fingerprints ([#7203](https://github.com/astral-sh/ruff/pull/7203))
-
-GitLab uses fingerprints to identify new, existing, or fixed violations. Previously, Ruff included the violation's position in the fingerprint. Using the location has the downside that changing any code before the violation causes the fingerprint to change, resulting in GitLab reporting one fixed and one new violation even though it is a pre-existing violation.
-
-Ruff now uses a more stable location-agnostic fingerprint to minimize that existing violations incorrectly get marked as fixed and re-reported as new violations.
-
-Expect GitLab to report each pre-existing violation in your project as fixed and a new violation in your Ruff upgrade PR.
-
-## 0.0.283 / 0.284
-
-### The target Python version now defaults to 3.8 instead of 3.10 ([#6397](https://github.com/astral-sh/ruff/pull/6397))
-
-Previously, when a target Python version was not specified, Ruff would use a default of Python 3.10. However, it is safer to default to an _older_ Python version to avoid assuming the availability of new features. We now default to the oldest supported Python version which is currently Python 3.8.
-
-(We still support Python 3.7 but since [it has reached EOL](https://devguide.python.org/versions/#unsupported-versions) we've decided not to make it the default here.)
-
-Note this change was announced in 0.0.283 but not active until 0.0.284.
-
-## 0.0.277
-
-### `.ipynb_checkpoints`, `.pyenv`, `.pytest_cache`, and `.vscode` are now excluded by default ([#5513](https://github.com/astral-sh/ruff/pull/5513))
-
-Ruff maintains a list of default exclusions, which now consists of the following patterns:
-
-- `.bzr`
-- `.direnv`
-- `.eggs`
-- `.git`
-- `.git-rewrite`
-- `.hg`
-- `.ipynb_checkpoints`
-- `.mypy_cache`
-- `.nox`
-- `.pants.d`
-- `.pyenv`
-- `.pytest_cache`
-- `.pytype`
-- `.ruff_cache`
-- `.svn`
-- `.tox`
-- `.venv`
-- `.vscode`
-- `__pypackages__`
-- `_build`
-- `buck-out`
-- `build`
-- `dist`
-- `node_modules`
-- `venv`
-
-Previously, the `.ipynb_checkpoints`, `.pyenv`, `.pytest_cache`, and `.vscode` directories were not
-excluded by default. This change brings Ruff's default exclusions in line with other tools like
-Black.
-
-## 0.0.276
-
-### The `keep-runtime-typing` setting has been reinstated ([#5470](https://github.com/astral-sh/ruff/pull/5470))
-
-The `keep-runtime-typing` setting has been reinstated with revised semantics. This setting was
-removed in [#4427](https://github.com/astral-sh/ruff/pull/4427), as it was equivalent to ignoring
-the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism.
-
-Taking `UP006` (rewrite `List[int]` to `list[int]`) as an example, the setting now behaves as
-follows:
-
-- On Python 3.7 and Python 3.8, setting `keep-runtime-typing = true` will cause Ruff to ignore
-    `UP006` violations, even if `from __future__ import annotations` is present in the file.
-    While such annotations are valid in Python 3.7 and Python 3.8 when combined with
-    `from __future__ import annotations`, they aren't supported by libraries like Pydantic and
-    FastAPI, which rely on runtime type checking.
-- On Python 3.9 and above, the setting has no effect, as `list[int]` is a valid type annotation,
-    and libraries like Pydantic and FastAPI support it without issue.
-
-In short: `keep-runtime-typing` can be used to ensure that Ruff doesn't introduce type annotations
-that are not supported at runtime by the current Python version, which are unsupported by libraries
-like Pydantic and FastAPI.
-
-Note that this is not a breaking change, but is included here to complement the previous removal
-of `keep-runtime-typing`.
-
-## 0.0.268
-
-### The `keep-runtime-typing` setting has been removed ([#4427](https://github.com/astral-sh/ruff/pull/4427))
-
-Enabling the `keep-runtime-typing` option, located under the `pyupgrade` section, is equivalent
-to ignoring the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism. As there's no
-need for a dedicated setting to disable these rules, the `keep-runtime-typing` option has been
-removed.
-
-## 0.0.267
-
-### `update-check` is no longer a valid configuration option ([#4313](https://github.com/astral-sh/ruff/pull/4313))
-
-The `update-check` functionality was deprecated in [#2530](https://github.com/astral-sh/ruff/pull/2530),
-in that the behavior itself was removed, and Ruff was changed to warn when that option was enabled.
-
-Now, Ruff will throw an error when `update-check` is provided via a configuration file (e.g.,
-`update-check = false`) or through the command-line, since it has no effect. Users should remove
-this option from their configuration.
-
-## 0.0.265
-
-### `--fix-only` now exits with a zero exit code, unless `--exit-non-zero-on-fix` is specified ([#4146](https://github.com/astral-sh/ruff/pull/4146))
-
-Previously, `--fix-only` would exit with a non-zero exit code if any fixes were applied. This
-behavior was inconsistent with `--fix`, and further, meant that `--exit-non-zero-on-fix` was
-effectively ignored when `--fix-only` was specified.
-
-Now, `--fix-only` will exit with a zero exit code, unless `--exit-non-zero-on-fix` is specified,
-in which case it will exit with a non-zero exit code if any fixes were applied.
-
-## 0.0.260
-
-### Fixes are now represented as a list of edits ([#3709](https://github.com/astral-sh/ruff/pull/3709))
-
-Previously, Ruff represented each fix as a single edit, which prohibited Ruff from automatically
-fixing violations that required multiple edits across a file. As such, Ruff now represents each
-fix as a list of edits.
-
-This primarily affects the JSON API. Ruff's JSON representation used to represent the `fix` field as
-a single edit, like so:
-
-```json
-{
-    "message": "Remove unused import: `sys`",
-    "content": "",
-    "location": {"row": 1, "column": 0},
-    "end_location": {"row": 2, "column": 0}
-}
-```
-
-The updated representation instead includes a list of edits:
-
-```json
-{
-    "message": "Remove unused import: `sys`",
-    "edits": [
-        {
-            "content": "",
-            "location": {"row": 1, "column": 0},
-            "end_location": {"row": 2, "column": 0},
-        }
-    ]
-}
-```
-
-## 0.0.246
-
-### `multiple-statements-on-one-line-def` (`E704`) was removed ([#2773](https://github.com/astral-sh/ruff/pull/2773))
-
-This rule was introduced in v0.0.245. However, it turns out that pycodestyle and Flake8 ignore this
-rule by default, as it is not part of PEP 8. As such, we've removed it from Ruff.
-
-## 0.0.245
-
-### Ruff's public `check` method was removed ([#2709](https://github.com/astral-sh/ruff/pull/2709))
-
-Previously, Ruff exposed a `check` method as a public Rust API. This method was used by few,
-if any clients, and was not well documented or supported. As such, it has been removed, with
-the intention of adding a stable public API in the future.
-
-## 0.0.238
-
-### `select`, `extend-select`, `ignore`, and `extend-ignore` have new semantics ([#2312](https://github.com/astral-sh/ruff/pull/2312))
-
-Previously, the interplay between `select` and its related options could lead to unexpected
-behavior. For example, `ruff --select E501 --ignore ALL` and `ruff --select E501 --extend-ignore ALL`
-behaved differently. (See [#2312](https://github.com/astral-sh/ruff/pull/2312) for more
-examples.)
-
-When Ruff determines the enabled rule set, it has to reconcile `select` and `ignore` from a variety
-of sources, including the current `pyproject.toml`, any inherited `pyproject.toml` files, and the
-CLI.
-
-The new semantics are such that Ruff uses the "highest-priority" `select` as the basis for the rule
-set, and then applies any `extend-select`, `ignore`, and `extend-ignore` adjustments. CLI options
-are given higher priority than `pyproject.toml` options, and the current `pyproject.toml` file is
-given higher priority than any inherited `pyproject.toml` files.
-
-`extend-select` and `extend-ignore` are no longer given "top priority"; instead, they merely append
-to the `select` and `ignore` lists, as in Flake8.
-
-This change is largely backwards compatible -- most users should experience no change in behavior.
-However, as an example of a breaking change, consider the following:
-
-```toml
-[tool.ruff]
-ignore = ["F401"]
-```
-
-Running `ruff --select F` would previously have enabled all `F` rules, apart from `F401`. Now, it
-will enable all `F` rules, including `F401`, as the command line's `--select` resets the resolution.
-
-### `remove-six-compat` (`UP016`) has been removed ([#2332](https://github.com/astral-sh/ruff/pull/2332))
-
-The `remove-six-compat` rule has been removed. This rule was only useful for one-time Python 2-to-3
-upgrades.
-
-## 0.0.237
-
-### `--explain`, `--clean`, and `--generate-shell-completion` are now subcommands ([#2190](https://github.com/astral-sh/ruff/pull/2190))
-
-`--explain`, `--clean`, and `--generate-shell-completion` are now implemented as subcommands:
-
-```console
-ruff .         # Still works! And will always work.
-ruff check .   # New! Also works.
-
-ruff --explain E402   # Still works.
-ruff rule E402        # New! Also works. (And preferred.)
-
-# Oops! The command has to come first.
-ruff --format json --explain E402   # No longer works.
-ruff --explain E402 --format json   # Still works!
-ruff rule E402   --format json      # Works! (And preferred.)
-```
-
-This change is largely backwards compatible -- most users should experience
-no change in behavior. However, please note the following exceptions:
-
-- Subcommands will now fail when invoked with unsupported arguments, instead
-    of silently ignoring them. For example, the following will now fail:
-
-    ```console
-    ruff --clean --respect-gitignore
-    ```
-
-    (the `clean` command doesn't support `--respect-gitignore`.)
-
-- The semantics of `ruff <arg>` have changed slightly when `<arg>` is a valid subcommand.
-    For example, prior to this release, running `ruff rule` would run `ruff` over a file or
-    directory called `rule`. Now, `ruff rule` would invoke the `rule` subcommand. This should
-    only impact projects with files or directories named `rule`, `check`, `explain`, `clean`,
-    or `generate-shell-completion`.
-
-- Scripts that invoke ruff should supply `--` before any positional arguments.
-    (The semantics of `ruff -- <arg>` have not changed.)
-
-- `--explain` previously treated `--format grouped` as a synonym for `--format text`.
-    This is no longer supported; instead, use `--format text`.
-
-## 0.0.226
-
-### `misplaced-comparison-constant` (`PLC2201`) was deprecated in favor of `SIM300` ([#1980](https://github.com/astral-sh/ruff/pull/1980))
-
-These two rules contain (nearly) identical logic. To deduplicate the rule set, we've upgraded
-`SIM300` to handle a few more cases, and deprecated `PLC2201` in favor of `SIM300`.
-
-## 0.0.225
-
-### `@functools.cache` rewrites have been moved to a standalone rule (`UP033`) ([#1938](https://github.com/astral-sh/ruff/pull/1938))
-
-Previously, `UP011` handled both `@functools.lru_cache()`-to-`@functools.lru_cache` conversions,
-_and_ `@functools.lru_cache(maxsize=None)`-to-`@functools.cache` conversions. The latter has been
-moved out to its own rule (`UP033`). As such, some `# noqa: UP011` comments may need to be updated
-to reflect the change in rule code.
-
-## 0.0.222
-
-### `--max-complexity` has been removed from the CLI ([#1877](https://github.com/astral-sh/ruff/pull/1877))
-
-The McCabe plugin's `--max-complexity` setting has been removed from the CLI, for consistency with
-the treatment of other, similar settings.
-
-To set the maximum complexity, use the `max-complexity` property in your `pyproject.toml` file,
-like so:
-
-```toml
-[tool.ruff.mccabe]
-max-complexity = 10
-```
-
-## 0.0.181
-
-### Files excluded by `.gitignore` are now ignored ([#1234](https://github.com/astral-sh/ruff/pull/1234))
-
-Ruff will now avoid checking files that are excluded by `.ignore`, `.gitignore`,
-`.git/info/exclude`, and global `gitignore` files. This behavior is powered by the [`ignore`](https://docs.rs/ignore/latest/ignore/struct.WalkBuilder.html#ignore-rules)
-crate, and is applied in addition to Ruff's built-in `exclude` system.
-
-To disable this behavior, set `respect-gitignore = false` in your `pyproject.toml` file.
-
-Note that hidden files (i.e., files and directories prefixed with a `.`) are _not_ ignored by
-default.
-
-## 0.0.178
-
-### Configuration files are now resolved hierarchically ([#1190](https://github.com/astral-sh/ruff/pull/1190))
-
-`pyproject.toml` files are now resolved hierarchically, such that for each Python file, we find
-the first `pyproject.toml` file in its path, and use that to determine its lint settings.
-
-See the [documentation](https://docs.astral.sh/ruff/configuration/#python-file-discovery) for more.

-pattern-match against the examples in the existing codebase. Many lint rules are inspired by
-existing Python plugins, which can be used as a reference implementation.
-
-As a concrete example: consider taking on one of the rules from the [`flake8-pyi`](https://github.com/astral-sh/ruff/issues/848)
-plugin, and looking to the originating [Python source](https://github.com/PyCQA/flake8-pyi) for
-guidance.
-
-If you have suggestions on how we might improve the contributing documentation, [let us know](https://github.com/astral-sh/ruff/discussions/5693)!
+Ruff welcomes contributions in the form of Pull Requests. For small changes (e.g., bug fixes), feel
+free to submit a PR. For larger changes (e.g., new lint rules, new functionality, new configuration
+options), consider submitting an [Issue](https://github.com/charliermarsh/ruff/issues) outlining
+your proposed change.

-### Project Structure
-
-Ruff is structured as a monorepo with a [flat crate structure](https://matklad.github.io/2021/08/22/large-rust-workspaces.html),
-such that all crates are contained in a flat `crates` directory.
-
-The vast majority of the code, including all lint rules, lives in the `ruff` crate (located at
-`crates/ruff`). As a contributor, that's the crate that'll be most relevant to you.
-
-At time of writing, the repository includes the following crates:
-
-- `crates/ruff`: library crate containing all lint rules and the core logic for running them.
-    If you're working on a rule, this is the crate for you.
-- `crates/ruff_benchmark`: binary crate for running micro-benchmarks.
-- `crates/ruff_cache`: library crate for caching lint results.
-- `crates/ruff_cli`: binary crate containing Ruff's command-line interface.
-- `crates/ruff_dev`: binary crate containing utilities used in the development of Ruff itself (e.g.,
-    `cargo dev generate-all`), see the [`cargo dev`](#cargo-dev) section below.
-- `crates/ruff_diagnostics`: library crate for the rule-independent abstractions in the lint
-    diagnostics APIs.
-- `crates/ruff_formatter`: library crate for language agnostic code formatting logic based on an
-    intermediate representation. The backend for `ruff_python_formatter`.
-- `crates/ruff_index`: library crate inspired by `rustc_index`.
-- `crates/ruff_macros`: proc macro crate containing macros used by Ruff.
-- `crates/ruff_notebook`: library crate for parsing and manipulating Jupyter notebooks.
-- `crates/ruff_python_ast`: library crate containing Python-specific AST types and utilities.
-- `crates/ruff_python_codegen`: library crate containing utilities for generating Python source code.
-- `crates/ruff_python_formatter`: library crate implementing the Python formatter. Emits an
-    intermediate representation for each node, which `ruff_formatter` prints based on the configured
-    line length.
-- `crates/ruff_python_semantic`: library crate containing Python-specific semantic analysis logic,
-    including Ruff's semantic model. Used to resolve queries like "What import does this variable
-    refer to?"
-- `crates/ruff_python_stdlib`: library crate containing Python-specific standard library data, e.g.
-    the names of all built-in exceptions and which standard library types are immutable.
-- `crates/ruff_python_trivia`: library crate containing Python-specific trivia utilities (e.g.,
-    for analyzing indentation, newlines, etc.).
-- `crates/ruff_python_parser`: library crate containing the Python parser.
-- `crates/ruff_wasm`: library crate for exposing Ruff as a WebAssembly module. Powers the
-    [Ruff Playground](https://play.ruff.rs/).

 ### Example: Adding a new lint rule
 
-At a high level, the steps involved in adding a new lint rule are as follows:
+There are four phases to adding a new lint rule:
 
-1. Determine a name for the new rule as per our [rule naming convention](#rule-naming-convention)
-    (e.g., `AssertFalse`, as in, "allow `assert False`").
+1. Define the rule in `src/checks.rs`.
+2. Define the _logic_ for triggering the rule in `src/check_ast.rs` (for AST-based checks),
+   `src/check_tokens.rs` (for token-based checks), or `src/check_lines.rs` (for text-based checks).
+3. Add a test fixture.
+4. Update the generated files (documentation and generated code).
 
-1. Create a file for your rule (e.g., `crates/ruff/src/rules/flake8_bugbear/rules/assert_false.rs`).
+To define the rule, open up `src/checks.rs`. You'll need to define both a `CheckCode` and
+`CheckKind`. As an example, you can grep for `E402` and `ModuleImportNotAtTopOfFile`, and follow the
+pattern implemented therein.
 
-1. In that file, define a violation struct (e.g., `pub struct AssertFalse`). You can grep for
-    `#[violation]` to see examples.
+To trigger the rule, you'll likely want to augment the logic in `src/check_ast.rs`, which defines
+the Python AST visitor, responsible for iterating over the abstract syntax tree and collecting
+lint-rule violations as it goes. If you need to inspect the AST, you can run `cargo dev print-ast`
+with a Python file. Grep for the `Check::new` invocations to understand how other, similar rules
+are implemented.
 
-1. In that file, define a function that adds the violation to the diagnostic list as appropriate
-    (e.g., `pub(crate) fn assert_false`) based on whatever inputs are required for the rule (e.g.,
-    an `ast::StmtAssert` node).
+To add a test fixture, create a file under `resources/test/fixtures`, named to match the `CheckCode`
+you defined earlier (e.g., `E402.py`). This file should contain a variety of violations and
+non-violations designed to evaluate and demonstrate the behavior of your lint rule. Run Ruff locally
+with (e.g.) `cargo run resources/test/fixtures/E402.py --no-cache`. Once you're satisfied with the
+output, codify the behavior as a snapshot test by adding a new `testcase` macro to the `mod tests`
+section of `src/linter.rs`, like so:
 
-1. Define the logic for invoking the diagnostic in `crates/ruff/src/checkers/ast/analyze` (for
-    AST-based rules), `crates/ruff/src/checkers/tokens.rs` (for token-based rules),
-    `crates/ruff/src/checkers/physical_lines.rs` (for text-based rules),
-    `crates/ruff/src/checkers/filesystem.rs` (for filesystem-based rules), etc. For AST-based rules,
-    you'll likely want to modify `analyze/statement.rs` (if your rule is based on analyzing
-    statements, like imports) or `analyze/expression.rs` (if your rule is based on analyzing
-    expressions, like function calls).
+```rust
+#[test_case(CheckCode::A001, Path::new("A001.py"); "A001")]
+...
+```
 
-1. Map the violation struct to a rule code in `crates/ruff/src/codes.rs` (e.g., `B011`).
+Then, run `cargo test`. Your test will fail, but you'll be prompted to follow-up with
+`cargo insta review`. Accept the generated snapshot, then commit the snapshot file alongside the
+rest of your changes.
 
-1. Add proper [testing](#rule-testing-fixtures-and-snapshots) for your rule.
-
-1. Update the generated files (documentation and generated code).
-
-To trigger the violation, you'll likely want to augment the logic in `crates/ruff/src/checkers/ast.rs`
-to call your new function at the appropriate time and with the appropriate inputs. The `Checker`
-defined therein is a Python AST visitor, which iterates over the AST, building up a semantic model,
-and calling out to lint rule analyzer functions as it goes.
-
-If you need to inspect the AST, you can run `cargo dev print-ast` with a Python file. Grep
-for the `Diagnostic::new` invocations to understand how other, similar rules are implemented.
-
-Once you're satisfied with your code, add tests for your rule. See [rule testing](#rule-testing-fixtures-and-snapshots)
-for more details.
-
-Finally, regenerate the documentation and other generated assets (like our JSON Schema) with:
-`cargo dev generate-all`.
-
-#### Rule naming convention
-
-Like Clippy, Ruff's rule names should make grammatical and logical sense when read as "allow
-${rule}" or "allow ${rule} items", as in the context of suppression comments.
-
-For example, `AssertFalse` fits this convention: it flags `assert False` statements, and so a
-suppression comment would be framed as "allow `assert False`".
-
-As such, rule names should...
-
-- Highlight the pattern that is being linted against, rather than the preferred alternative.
-    For example, `AssertFalse` guards against `assert False` statements.
-
-- _Not_ contain instructions on how to fix the violation, which instead belong in the rule
-    documentation and the `autofix_title`.
-
-- _Not_ contain a redundant prefix, like `Disallow` or `Banned`, which are already implied by the
-    convention.
-
-When re-implementing rules from other linters, we prioritize adhering to this convention over
-preserving the original rule name.
-
-#### Rule testing: fixtures and snapshots
-
-To test rules, Ruff uses snapshots of Ruff's output for a given file (fixture). Generally, there
-will be one file per rule (e.g., `E402.py`), and each file will contain all necessary examples of
-both violations and non-violations. `cargo insta review` will generate a snapshot file containing
-Ruff's output for each fixture, which you can then commit alongside your changes.
-
-Once you've completed the code for the rule itself, you can define tests with the following steps:
-
-1. Add a Python file to `crates/ruff/resources/test/fixtures/[linter]` that contains the code you
-    want to test. The file name should match the rule name (e.g., `E402.py`), and it should include
-    examples of both violations and non-violations.
-
-1. Run Ruff locally against your file and verify the output is as expected. Once you're satisfied
-    with the output (you see the violations you expect, and no others), proceed to the next step.
-    For example, if you're adding a new rule named `E402`, you would run:
-
-    ```shell
-    cargo run -p ruff_cli -- check crates/ruff/resources/test/fixtures/pycodestyle/E402.py --no-cache --select E402
-    ```
-
-    **Note:** Only a subset of rules are enabled by default. When testing a new rule, ensure that
-    you activate it by adding `--select ${rule_code}` to the command.
-
-1. Add the test to the relevant `crates/ruff/src/rules/[linter]/mod.rs` file. If you're contributing
-    a rule to a pre-existing set, you should be able to find a similar example to pattern-match
-    against. If you're adding a new linter, you'll need to create a new `mod.rs` file (see,
-    e.g., `crates/ruff/src/rules/flake8_bugbear/mod.rs`)
-
-1. Run `cargo test`. Your test will fail, but you'll be prompted to follow-up
-    with `cargo insta review`. Run `cargo insta review`, review and accept the generated snapshot,
-    then commit the snapshot file alongside the rest of your changes.
-
-1. Run `cargo test` again to ensure that your test passes.
+Finally, to update the documentation, run `cargo dev generate-rules-table` from the repo root. To
+update the generated prefix map, run `cargo dev generate-check-code-prefix`. Both of these commands
+should be run whenever a new check is added to the codebase.
 
 ### Example: Adding a new configuration option
 
-Ruff's user-facing settings live in a few different places.
+Ruff's user-facing settings live in two places: first, the command-line options defined with
+[clap](https://docs.rs/clap/latest/clap/) via the `Cli` struct in `src/main.rs`; and second, the
+`Config` struct defined `src/pyproject.rs`, which is responsible for extracting user-defined
+settings from a `pyproject.toml` file.
 
-First, the command-line options are defined via the `Cli` struct in `crates/ruff/src/cli.rs`.
+Ultimately, these two sources of configuration are merged into the `Settings` struct defined
+in `src/settings.rs`, which is then threaded through the codebase.
 
-Second, the `pyproject.toml` options are defined in `crates/ruff/src/settings/options.rs` (via the
-`Options` struct), `crates/ruff/src/settings/configuration.rs` (via the `Configuration` struct), and
-`crates/ruff/src/settings/mod.rs` (via the `Settings` struct). These represent, respectively: the
-schema used to parse the `pyproject.toml` file; an internal, intermediate representation; and the
-final, internal representation used to power Ruff.
+To add a new configuration option, you'll likely want to _both_ add a CLI option to `src/main.rs`
+_and_ a `pyproject.toml` parameter to `src/pyproject.rs`. If you want to pattern-match against an
+existing example, grep for `dummy_variable_rgx`, which defines a regular expression to match against
+acceptable unused variables (e.g., `_`).
 
-To add a new configuration option, you'll likely want to modify these latter few files (along with
-`cli.rs`, if appropriate). If you want to pattern-match against an existing example, grep for
-`dummy_variable_rgx`, which defines a regular expression to match against acceptable unused
-variables (e.g., `_`).
-
-Note that plugin-specific configuration options are defined in their own modules (e.g.,
-`crates/ruff/src/flake8_unused_arguments/settings.rs`).
+If the new plugin's configuration should be cached between runs, you'll need to add it to the
+`Hash` implementation for `Settings` in `src/settings/mod.rs`.
 
 You may also want to add the new configuration option to the `flake8-to-ruff` tool, which is
 responsible for converting `flake8` configuration files to Ruff's TOML format. This logic
-lives in `crates/ruff/src/flake8_to_ruff/converter.rs`.
+lives in `flake8_to_ruff/src/converter.rs`.
 
-Finally, regenerate the documentation and generated code with `cargo dev generate-all`.
-
-## MkDocs
-
-To preview any changes to the documentation locally:
-
-1. Install the [Rust toolchain](https://www.rust-lang.org/tools/install).
-
-1. Install MkDocs and Material for MkDocs with:
-
-    ```shell
-    pip install -r docs/requirements.txt
-    ```
-
-1. Generate the MkDocs site with:
-
-    ```shell
-    python scripts/generate_mkdocs.py
-    ```
-
-1. Run the development server with:
-
-    ```shell
-    # For contributors.
-    mkdocs serve -f mkdocs.generated.yml
-
-    # For members of the Astral org, which has access to MkDocs Insiders via sponsorship.
-    mkdocs serve -f mkdocs.insiders.yml
-    ```
-
-The documentation should then be available locally at
-[http://127.0.0.1:8000/docs/](http://127.0.0.1:8000/docs/).

-## Release Process
+## Release process
 
 As of now, Ruff has an ad hoc release process: releases are cut with high frequency via GitHub
 Actions, which automatically generates the appropriate wheels across architectures and publishes
@@ -312,570 +113,3 @@ them to [PyPI](https://pypi.org/project/ruff/).
 
 Ruff follows the [semver](https://semver.org/) versioning standard. However, as pre-1.0 software,
 even patch releases may contain [non-backwards-compatible changes](https://semver.org/#spec-item-4).
-
-### Creating a new release
-
-1. Update the version with `rg 0.0.269 --files-with-matches | xargs sed -i 's/0.0.269/0.0.270/g'`
-1. Update `BREAKING_CHANGES.md`
-1. Create a PR with the version and `BREAKING_CHANGES.md` updated
-1. Merge the PR
-1. Run the release workflow with the version number (without starting `v`) as input. Make sure
-    main has your merged PR as last commit
-1. The release workflow will do the following:
-    1. Build all the assets. If this fails (even though we tested in step 4), we haven't tagged or
-        uploaded anything, you can restart after pushing a fix.
-    1. Upload to PyPI.
-    1. Create and push the Git tag (as extracted from `pyproject.toml`). We create the Git tag only
-        after building the wheels and uploading to PyPI, since we can't delete or modify the tag ([#4468](https://github.com/charliermarsh/ruff/issues/4468)).
-    1. Attach artifacts to draft GitHub release
-    1. Trigger downstream repositories. This can fail non-catastrophically, as we can run any
-        downstream jobs manually if needed.
-1. Create release notes in GitHub UI and promote from draft.
-1. If needed, [update the schemastore](https://github.com/charliermarsh/ruff/blob/main/scripts/update_schemastore.py)
-1. If needed, update the `ruff-lsp` and `ruff-vscode` repositories.
-
-## Ecosystem CI
-
-GitHub Actions will run your changes against a number of real-world projects from GitHub and
-report on any diagnostic differences. You can also run those checks locally via:
-
-```shell
-python scripts/check_ecosystem.py path/to/your/ruff path/to/older/ruff
-```
-
-You can also run the Ecosystem CI check in a Docker container across a larger set of projects by
-downloading the [`known-github-tomls.json`](https://github.com/akx/ruff-usage-aggregate/blob/master/data/known-github-tomls.jsonl)
-as `github_search.jsonl` and following the instructions in [scripts/Dockerfile.ecosystem](https://github.com/astral-sh/ruff/blob/main/scripts/Dockerfile.ecosystem).
-Note that this check will take a while to run.
-
-## Benchmarking and Profiling
-
-We have several ways of benchmarking and profiling Ruff:
-
-- Our main performance benchmark comparing Ruff with other tools on the CPython codebase
-- Microbenchmarks which the linter or the formatter on individual files. There run on pull requests.
-- Profiling the linter on either the microbenchmarks or entire projects

-The `ruff_benchmark` crate benchmarks the linter and the formatter on individual files.
-
-You can run the benchmarks with
-
-```shell
-cargo benchmark
-```
-
-#### Benchmark-driven Development
-
-Ruff uses [Criterion.rs](https://bheisler.github.io/criterion.rs/book/) for benchmarks. You can use
-`--save-baseline=<name>` to store an initial baseline benchmark (e.g. on `main`) and then use
-`--benchmark=<name>` to compare against that benchmark. Criterion will print a message telling you
-if the benchmark improved/regressed compared to that baseline.
-
-```shell
-# Run once on your "baseline" code
-cargo benchmark --save-baseline=main
-
-# Then iterate with
-cargo benchmark --baseline=main
-```
-
-#### PR Summary
-
-You can use `--save-baseline` and `critcmp` to get a pretty comparison between two recordings.
-This is useful to illustrate the improvements of a PR.
-
-```shell
-# On main
-cargo benchmark --save-baseline=main
-
-# After applying your changes
-cargo benchmark --save-baseline=pr
-
-critcmp main pr
-```
-
-You must install [`critcmp`](https://github.com/BurntSushi/critcmp) for the comparison.
-
-```bash
-cargo install critcmp
-```
-
-#### Tips
-
-- Use `cargo benchmark <filter>` to only run specific benchmarks. For example: `cargo benchmark linter/pydantic`
-    to only run the pydantic tests.
-- Use `cargo benchmark --quiet` for a more cleaned up output (without statistical relevance)
-- Use `cargo benchmark --quick` to get faster results (more prone to noise)
-
-### Profiling Projects
-
-You can either use the microbenchmarks from above or a project directory for benchmarking. There
-are a lot of profiling tools out there,
-[The Rust Performance Book](https://nnethercote.github.io/perf-book/profiling.html) lists some
-examples.
-
-#### Linux
-
-Install `perf` and build `ruff_benchmark` with the `release-debug` profile and then run it with perf
-
-```shell
-cargo bench -p ruff_benchmark --no-run --profile=release-debug && perf record --call-graph dwarf -F 9999 cargo bench -p ruff_benchmark --profile=release-debug -- --profile-time=1
-```
-
-You can also use the `ruff_dev` launcher to run `ruff check` multiple times on a repository to
-gather enough samples for a good flamegraph (change the 999, the sample rate, and the 30, the number
-of checks, to your liking)
-
-```shell
-cargo build --bin ruff_dev --profile=release-debug
-perf record -g -F 999 target/release-debug/ruff_dev repeat --repeat 30 --exit-zero --no-cache path/to/cpython > /dev/null
-```
-
-Then convert the recorded profile
-
-```shell
-perf script -F +pid > /tmp/test.perf
-```
-
-You can now view the converted file with [firefox profiler](https://profiler.firefox.com/), with a
-more in-depth guide [here](https://profiler.firefox.com/docs/#/./guide-perf-profiling)
-
-An alternative is to convert the perf data to `flamegraph.svg` using
-[flamegraph](https://github.com/flamegraph-rs/flamegraph) (`cargo install flamegraph`):
-
-```shell
-flamegraph --perfdata perf.data --no-inline
-```
-
-#### Mac
-
-Install [`cargo-instruments`](https://crates.io/crates/cargo-instruments):
-
-```shell
-cargo install cargo-instruments
-```
-
-Then run the profiler with
-
-```shell
-cargo instruments -t time --bench linter --profile release-debug -p ruff_benchmark -- --profile-time=1
-```
-
-- `-t`: Specifies what to profile. Useful options are `time` to profile the wall time and `alloc`
-    for profiling the allocations.
-- You may want to pass an additional filter to run a single test file
-
-Otherwise, follow the instructions from the linux section.
-
-## `cargo dev`
-
-`cargo dev` is a shortcut for `cargo run --package ruff_dev --bin ruff_dev`. You can run some useful
-utils with it:
-
-- `cargo dev print-ast <file>`: Print the AST of a python file using the
-    [RustPython parser](https://github.com/astral-sh/RustPython-Parser/tree/main/parser) that is
-    mainly used in Ruff. For `if True: pass # comment`, you can see the syntax tree, the byte offsets
-    for start and stop of each node and also how the `:` token, the comment and whitespace are not
-    represented anymore:
-
-```text
-[
-    If(
-        StmtIf {
-            range: 0..13,
-            test: Constant(
-                ExprConstant {
-                    range: 3..7,
-                    value: Bool(
-                        true,
-                    ),
-                    kind: None,
-                },
-            ),
-            body: [
-                Pass(
-                    StmtPass {
-                        range: 9..13,
-                    },
-                ),
-            ],
-            orelse: [],
-        },
-    ),
-]
-```
-
-- `cargo dev print-tokens <file>`: Print the tokens that the AST is built upon. Again for
-    `if True: pass # comment`:
-
-```text
-0 If 2
-3 True 7
-7 Colon 8
-9 Pass 13
-14 Comment(
-    "# comment",
-) 23
-23 Newline 24
-```
-
-- `cargo dev print-cst <file>`: Print the CST of a python file using
-    [LibCST](https://github.com/Instagram/LibCST), which is used in addition to the RustPython parser
-    in Ruff. E.g. for `if True: pass # comment` everything including the whitespace is represented:
-
-```text
-Module {
-    body: [
-        Compound(
-            If(

-## Subsystems
-
-### Compilation Pipeline
-
-If we view Ruff as a compiler, in which the inputs are paths to Python files and the outputs are
-diagnostics, then our current compilation pipeline proceeds as follows:
-
-1. **File discovery**: Given paths like `foo/`, locate all Python files in any specified subdirectories, taking into account our hierarchical settings system and any `exclude` options.
-
-1. **Package resolution**: Determine the "package root" for every file by traversing over its parent directories and looking for `__init__.py` files.
-
-1. **Cache initialization**: For every "package root", initialize an empty cache.
-
-1. **Analysis**: For every file, in parallel:
-
-    1. **Cache read**: If the file is cached (i.e., its modification timestamp hasn't changed since it was last analyzed), short-circuit, and return the cached diagnostics.
-
-    1. **Tokenization**: Run the lexer over the file to generate a token stream.
-
-    1. **Indexing**: Extract metadata from the token stream, such as: comment ranges, `# noqa` locations, `# isort: off` locations, "doc lines", etc.
-
-    1. **Token-based rule evaluation**: Run any lint rules that are based on the contents of the token stream (e.g., commented-out code).
-
-    1. **Filesystem-based rule evaluation**: Run any lint rules that are based on the contents of the filesystem (e.g., lack of `__init__.py` file in a package).
-
-    1. **Logical line-based rule evaluation**: Run any lint rules that are based on logical lines (e.g., stylistic rules).
-
-    1. **Parsing**: Run the parser over the token stream to produce an AST. (This consumes the token stream, so anything that relies on the token stream needs to happen before parsing.)
-
-    1. **AST-based rule evaluation**: Run any lint rules that are based on the AST. This includes the vast majority of lint rules. As part of this step, we also build the semantic model for the current file as we traverse over the AST. Some lint rules are evaluated eagerly, as we iterate over the AST, while others are evaluated in a deferred manner (e.g., unused imports, since we can't determine whether an import is unused until we've finished analyzing the entire file), after we've finished the initial traversal.
-
-    1. **Import-based rule evaluation**: Run any lint rules that are based on the module's imports (e.g., import sorting). These could, in theory, be included in the AST-based rule evaluation phase — they're just separated for simplicity.
-
-    1. **Physical line-based rule evaluation**: Run any lint rules that are based on physical lines (e.g., line-length).
-
-    1. **Suppression enforcement**: Remove any violations that are suppressed via `# noqa` directives or `per-file-ignores`.
-
-    1. **Cache write**: Write the generated diagnostics to the package cache using the file as a key.
-
-1. **Reporting**: Print diagnostics in the specified format (text, JSON, etc.), to the specified output channel (stdout, a file, etc.).
-
-### Import Categorization
-
-To understand Ruff's import categorization system, we first need to define two concepts:
-
-- "Project root": The directory containing the `pyproject.toml`, `ruff.toml`, or `.ruff.toml` file,
-    discovered by identifying the "closest" such directory for each Python file. (If you're running
-    via `ruff --config /path/to/pyproject.toml`, then the current working directory is used as the
-    "project root".)
-- "Package root": The top-most directory defining the Python package that includes a given Python
-    file. To find the package root for a given Python file, traverse up its parent directories until
-    you reach a parent directory that doesn't contain an `__init__.py` file (and isn't marked as
-    a [namespace package](https://docs.astral.sh/ruff/settings/#namespace-packages)); take the directory
-    just before that, i.e., the first directory in the package.
-
-For example, given:
-
-```text
-my_project
-├── pyproject.toml
-└── src
-    └── foo
-        ├── __init__.py
-        └── bar
-            ├── __init__.py
-            └── baz.py
-```
-
-Then when analyzing `baz.py`, the project root would be the top-level directory (`./my_project`),
-and the package root would be `./my_project/src/foo`.
-
-#### Project root
-
-The project root does not have a significant impact beyond that all relative paths within the loaded
-configuration file are resolved relative to the project root.
-
-For example, to indicate that `bar` above is a namespace package (it isn't, but let's run with it),
-the `pyproject.toml` would list `namespace-packages = ["./src/bar"]`, which would resolve
-to `my_project/src/bar`.
-
-The same logic applies when providing a configuration file via `--config`. In that case, the
-_current working directory_ is used as the project root, and so all paths in that configuration file
-are resolved relative to the current working directory. (As a general rule, we want to avoid relying
-on the current working directory as much as possible, to ensure that Ruff exhibits the same behavior
-regardless of where and how you invoke it — but that's hard to avoid in this case.)
-
-Additionally, if a `pyproject.toml` file _extends_ another configuration file, Ruff will still use
-the directory containing that `pyproject.toml` file as the project root. For example, if
-`./my_project/pyproject.toml` contains:
-
-```toml
-[tool.ruff]
-extend = "/path/to/pyproject.toml"
-```
-
-Then Ruff will use `./my_project` as the project root, even though the configuration file extends
-`/path/to/pyproject.toml`. As such, if the configuration file at `/path/to/pyproject.toml` contains
-any relative paths, they will be resolved relative to `./my_project`.
-
-If a project uses nested configuration files, then Ruff would detect multiple project roots, one for
-each configuration file.
-
-#### Package root
-
-The package root is used to determine a file's "module path". Consider, again, `baz.py`. In that
-case, `./my_project/src/foo` was identified as the package root, so the module path for `baz.py`
-would resolve to  `foo.bar.baz` — as computed by taking the relative path from the package root
-(inclusive of the root itself). The module path can be thought of as "the path you would use to
-import the module" (e.g., `import foo.bar.baz`).
-
-The package root and module path are used to, e.g., convert relative to absolute imports, and for
-import categorization, as described below.
-
-#### Import categorization
-
-When sorting and formatting import blocks, Ruff categorizes every import into one of five
-categories:
-
-1. **"Future"**: the import is a `__future__` import. That's easy: just look at the name of the
-    imported module!
-1. **"Standard library"**: the import comes from the Python standard library (e.g., `import os`).
-    This is easy too: we include a list of all known standard library modules in Ruff itself, so it's
-    a simple lookup.
-1. **"Local folder"**: the import is a relative import (e.g., `from .foo import bar`). This is easy
-    too: just check if the import includes a `level` (i.e., a dot-prefix).
-1. **"First party"**: the import is part of the current project. (More on this below.)
-1. **"Third party"**: everything else.
-
-The real challenge lies in determining whether an import is first-party — everything else is either
-trivial, or (as in the case of third-party) merely defined as "not first-party".
-
-There are three ways in which an import can be categorized as "first-party":
-
-1. **Explicit settings**: the import is marked as such via the `known-first-party` setting. (This
-    should generally be seen as an escape hatch.)
-1. **Same-package**: the imported module is in the same package as the current file. This gets back
-    to the importance of the "package root" and the file's "module path". Imagine that we're
-    analyzing `baz.py` above. If `baz.py` contains any imports that appear to come from the `foo`
-    package (e.g., `from foo import bar` or `import foo.bar`), they'll be classified as first-party
-    automatically. This check is as simple as comparing the first segment of the current file's
-    module path to the first segment of the import.
-1. **Source roots**: Ruff supports a `[src](https://docs.astral.sh/ruff/settings/#src)` setting, which
-    sets the directories to scan when identifying first-party imports. The algorithm is
-    straightforward: given an import, like `import foo`, iterate over the directories enumerated in
-    the `src` setting and, for each directory, check for the existence of a subdirectory `foo` or a
-    file `foo.py`.
-
-By default, `src` is set to the project root. In the above example, we'd want to set
-`src = ["./src"]` to ensure that we locate `./my_project/src/foo` and thus categorize `import foo`
-as first-party in `baz.py`. In practice, for this limited example, setting `src = ["./src"]` is
-unnecessary, as all imports within `./my_project/src/foo` would be categorized as first-party via
-the same-package heuristic; but your project contains multiple packages, you'll want to set `src`
-explicitly.

-# flake8-to-ruff
-
-Convert existing Flake8 configuration files (`setup.cfg`, `tox.ini`, or `.flake8`) for use with
-[Ruff](https://github.com/astral-sh/ruff).
-
-Generates a Ruff-compatible `pyproject.toml` section.
-
-## Installation and Usage
-
-### Installation
-
-Available as [`flake8-to-ruff`](https://pypi.org/project/flake8-to-ruff/) on PyPI:
-
-```shell
-pip install flake8-to-ruff
-```
-
-### Usage
-
-To run `flake8-to-ruff`:
-
-```shell
-flake8-to-ruff path/to/setup.cfg
-flake8-to-ruff path/to/tox.ini
-flake8-to-ruff path/to/.flake8
-```
-
-`flake8-to-ruff` will print the relevant `pyproject.toml` sections to standard output, like so:
-
-```toml
-[tool.ruff]
-exclude = [
-    '.svn',
-    'CVS',
-    '.bzr',
-    '.hg',
-    '.git',
-    '__pycache__',
-    '.tox',
-    '.idea',
-    '.mypy_cache',
-    '.venv',
-    'node_modules',
-    '_state_machine.py',
-    'test_fstring.py',
-    'bad_coding2.py',
-    'badsyntax_*.py',
-]
-select = [
-    'A',
-    'E',
-    'F',
-    'Q',
-]
-ignore = []
-
-[tool.ruff.flake8-quotes]
-inline-quotes = 'single'
-
-[tool.ruff.pep8-naming]
-ignore-names = [
-    'foo',
-    'bar',
-]
-```
-
-### Plugins
-
-`flake8-to-ruff` will attempt to infer any activated plugins based on the settings provided in your
-configuration file.
-
-For example, if your `.flake8` file includes a `docstring-convention` property, `flake8-to-ruff`
-will enable the appropriate [`flake8-docstrings`](https://pypi.org/project/flake8-docstrings/)
-checks.
-
-Alternatively, you can manually specify plugins on the command-line:
-
-```shell
-flake8-to-ruff path/to/.flake8 --plugin flake8-builtins --plugin flake8-quotes
-```
-
-## Limitations
-
-1. Ruff only supports a subset of the Flake configuration options. `flake8-to-ruff` will warn on and
-    ignore unsupported options in the `.flake8` file (or equivalent). (Similarly, Ruff has a few
-    configuration options that don't exist in Flake8.)
-1. Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule
-    codes from unsupported plugins. (See the
-    [documentation](https://docs.astral.sh/ruff/faq/#how-does-ruff-compare-to-flake8) for the complete
-    list of supported plugins.)
