## Summary
We're planning to move the documentation from
[https://beta.ruff.rs/docs](https://beta.ruff.rs/docs) to
[https://docs.astral.sh/ruff](https://docs.astral.sh/ruff), for a few
reasons:
1. We want to remove the `beta` from the domain, as Ruff is no longer
considered beta software.
2. We want to migrate to a structure that could accommodate multiple
future tools living under one domain.
The docs are actually already live at
[https://docs.astral.sh/ruff](https://docs.astral.sh/ruff), but later
today, I'll add a permanent redirect from the previous to the new
domain. **All existing links will continue to work, now and in
perpetuity.**
This PR contains the code changes necessary for the updated
documentation. As part of this effort, I moved the playground and
documentation from my personal Cloudflare account to our team Cloudflare
account (hence the new `--project-name` references). After merging, I'll
also update the secrets on this repo.
## Summary
This PR moves `ruff/jupyter` into its own `ruff_notebook` crate. Beyond
the move itself, there were a few challenges:
1. `ruff_notebook` relies on the source map abstraction. I've moved the
source map into `ruff_diagnostics`, since it doesn't have any
dependencies on its own and is used alongside diagnostics.
2. `ruff_notebook` has a couple tests for end-to-end linting and
autofixing. I had to leave these tests in `ruff` itself.
3. We had code in `ruff/jupyter` that relied on Python lexing, in order
to provide a more targeted error message in the event that a user saves
a `.py` file with a `.ipynb` extension. I removed this in order to avoid
a dependency on the parser, it felt like it wasn't worth retaining just
for that dependency.
## Test Plan
`cargo test`
**Summary** Some files seems notoriously slow in the formatter (secons in debug mode). This time was however almost exclusively spent in the diff algorithm to collect the similarity index, so i replaced that. I kept `similar` for printing actual diff to avoid rewriting that too, with the disadvantage that we now have to diff libraries in format_dev.
I used this PR to remove the spinner from tracing-indicatif and changed `flamegraph --perfdata perf.data` to `flamegraph --perfdata perf.data --no-inline` as the former wouldn't finish for me on release builds with debug info.

## Summary
In Ruff only a subset of rules are enabled by default. This change
change aims to clarify that when adding a new rule, you must explicitly
use the `--select name_of_rule` command to ensure the rule gets
executed.
This was talked about on Discord a while back.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
As of right now, the instructions don't specify where to run ruff from
after cloning the repository this is to address that. Super trivial
change, but helpful for real newbies I think.
## Summary
This PR attempts to draw some basic separation between the `Checker`'s
traversal responsibilities (traversing the AST, building the semantic
model) and its calling-out-to-lint-rule responsibilities. It doesn't try
to introduce any sophisticated API. Instead, it just moves all of the
lint rule calls out of `checkers/ast/mod.rs` and into methods in a new
`analyze` module. (There are four remaining lint rules in `Checker`, but
I'll remove those in future PRs.)
I'm not trying to "solve" our lint rule API here. Instead, I'm trying to
make two improvements:
1. `checkers/ast/mod.rs` has just gotten way too large, and people work
in it all the time. Prior to this PR, it was 5.5k lines, which led to
significant lags in my editor and made it really hard to reason about
the parts that are _actually_ important. (I like big files, but this one
crossed the line for me.) Now, it's < 2,000 lines, and the code is much
more focused.
2. I want to avoid accidentally adding lint rules in the "wrong" parts
of the traversal. By confining lint rule invocations to these "analyze"
calls, we'll avoid (e.g.) putting them in the binding phase.
## Summary
This crate now contains utilities for dealing with trivia more broadly:
whitespace, newlines, "simple" trivia lexing, etc. So renaming it to
reflect its increased responsibilities.
To avoid conflicts, I've also renamed `Token` and `TokenKind` to
`SimpleToken` and `SimpleTokenKind`.
Moves the computation of the `start_offset` for overlong lines to just
before the result is returned. There is a slight overhead for overlong
lines (double the work for the first `limit` characters).
In practice this results in a speedup on the CPython codebase. Most
lines are not overlong, or are not enforced because the line ends with a
URL, or does not contain whitespace. Nonetheless, the 0.3% of overlong
lines are a lot compared to other violations.

## Summary
Document all `ruff_dev` subcommands and document the `format_dev` flags
in the formatter readme.
CC @zanieb please flag everything that isn't clear or missing
## Test Plan
n/a
This moves all docs about benchmarking and profiling into
CONTRIBUTING.md by moving the readme of `ruff_benchmark` and adding more
information on profiling.
We need to somehow consolidate that documentation, but i'm not convinced
that this is the best way (i tried subpages in mkdocs, but that didn't
seem good either), so i'm happy to take suggestions.
## Summary
Currently, it is possible to create a tag and then have the release
fail, which is a problem since we can't edit the tag
(https://github.com/charliermarsh/ruff/issues/4468). This change the
release process so that the tag is created inside the release workflow.
This leaves as a failure mode that we have published to pypi but then
creating the tag or GitHub release doesn't work, but in this case we can
restart and the pypi upload is just skipped because we use the skip
existing option.
The release workflow is started by a workflow dispatch with the tag
instead of creating the tag yourself. You can start the release workflow
without a tag to do a dry run which does not publish an artifacts. You
can optionally add a git sha to the workflow run and it will verify that
the release runs on the mentioned commit.
This also adds docs on how to release and a small style improvement for
the maturin integration.
## Test Plan
Testing is hard since we can't do real releases, i've tested a minimized
workflow in a separate dummy repository.
This tackles three problems:
* pre-commit was slow because it ran cargo commands
* Improve the clarity on what you need to run to get your PR pass on CI
(and make those fast)
* You had to compile and run `cargo dev generate-all` separately, which
was slow
The first change is to remove all cargo commands except running ruff
itself from pre-commit. With `cargo run --bin ruff` already compiled it
takes about 7s on my machine. It would make sense to also use the ruff
pre-commit action here even if we're then lagging a release behind for
checking ruff on ruff.
The contributing guide is now clear about what you need to run:
```shell
cargo clippy --workspace --all-targets --all-features -- -D warnings # Linting...
RUFF_UPDATE_SCHEMA=1 cargo test # Testing and updating ruff.schema.json
pre-commit run --all-files # rust and python formatting, markdown and python linting, etc.
```
Example timings from my machine:
`cargo clippy --workspace --all-targets --all-features -- -D warnings`:
23s
`RUFF_UPDATE_SCHEMA=1 cargo test`: 2min (recompiling), 1min (no code
changes, this is mainly doc tests)
`pre-commit run --all-files`: 7s
The exact numbers don't matter so much as the approximate experience (6s
is easier to just wait than 1min, esp if you need to fix and rerun). The
biggest remaining block seems to be doc tests, i'm surprised i didn't
find any solution to speeding them up (nextest simply doesn't run them
at all). Also note that the formatter has it's own tests which are much
faster since they avoid linking ruff (`cargo test
ruff_python_formatter`).
The third change is to enable `cargo test` to update the schema. Similar
to `INSTA_UPDATE=always`, i've added `RUFF_UPDATE_SCHEMA=1` (name open
to bikeshedding), so `RUFF_UPDATE_SCHEMA=1 cargo test` updates the
schema, while `cargo test` still fails as expected if the repo isn't
up-to-date.
