## Summary
This adds a new subcommand that can be used as
```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
flamegraph --perfdata perf.data
```
## Test Plan
This is a ruff internal script. I successfully used it to profile
cpython with the instructions above
## Summary
We now _always_ generate fixes, so `FixMode::None` and
`FixMode::Generate` are redundant. We can also remove the TODO around
`--fix-dry-run`, since that's our default behavior.
Closes#5081.
## Summary
This adds `json-lines` (https://jsonlines.org/ or http://ndjson.org/) as
an output format.
I'm sure you already know, but
* JSONL is more greppable (each record is a single line) than the pretty
JSON
* JSONL is faster to ingest piecewise (and/or in parallel) than JSON
## Test Plan
Snapshot test in the new module :)
## Summary
Add support for applying auto-fixes in Jupyter Notebook.
### Solution
Cell offsets are the boundaries for each cell in the concatenated source
code. They are represented using `TextSize`. It includes the start and
end offset as well, thus creating a range for each cell. These offsets
are updated using the `SourceMap` markers.
### SourceMap
`SourceMap` contains markers constructed from each edits which tracks
the original source code position to the transformed positions. The
following drawing might make it clear:
The center column where the dotted lines are present are the markers
included in the `SourceMap`. The `Notebook` looks at these markers and
updates the cell offsets after each linter loop. If you notice closely,
the destination takes into account all of the markers before it.
The index is constructed only when required as it's only used to render
the diagnostics. So, a `OnceCell` is used for this purpose. The cell
offsets, cell content and the index will be updated after each iteration
of linting in the mentioned order. The order is important here as the
content is updated as per the new offsets and index is updated as per
the new content.
## Limitations
### 1
Styling rules such as the ones in `pycodestyle` will not be applicable
everywhere in Jupyter notebook, especially at the cell boundaries. Let's
take an example where a rule suggests to have 2 blank lines before a
function and the cells contains the following code:
```python
import something
# ---
def first():
pass
def second():
pass
```
(Again, the comment is only to visualize cell boundaries.)
In the concatenated source code, the 2 blank lines will be added but it
shouldn't actually be added when we look in terms of Jupyter notebook.
It's as if the function `first` is at the start of a file.
`nbqa` solves this by recording newlines before and after running
`autopep8`, then running the tool and restoring the newlines at the end
(refer https://github.com/nbQA-dev/nbQA/pull/807).
## Test Plan
Three commands were run in order with common flags (`--select=ALL
--no-cache --isolated`) to isolate which stage the problem is occurring:
1. Only diagnostics
2. Fix with diff (`--fix --diff`)
3. Fix (`--fix`)

## Summary
Ignore pyproject.toml file for adding noqa directives using `--add-noqa`
## Test Plan
`cargo run --bin ruff -- check --add-noqa .`
fixes: #5012
* Use dummy verbatim formatter for all nodes
* Use new formatter infrastructure in CLI and test
* Expose the new formatter in the CLI
* Merge import blocks
This adds a new rule `InvalidPyprojectToml` that lints pyproject.toml by checking if https://github.com/PyO3/pyproject-toml-rs can parse it. This means the linting is currently very basic, e.g. we don't check whether the name is actually a valid python project name or appropriately normalized. It does catch errors e.g. with invalid dependency requirements or problems withs the license specifications. It is open to be extended in the future (validate name, SPDX expressions, classifiers, ...), either in ruff or in pyproject-toml-rs.
Test plan:
```
scripts/ecosystem_all_check.sh check --select RUF200
```
This lead to a bunch of
```
RUF200 Failed to parse pyproject.toml: missing field `name`
```
(e.g. https://github.com/amitsk/fastapi-todos/blob/main/pyproject.toml) which is indeed invalid (https://packaging.python.org/en/latest/specifications/declaring-project-metadata/#specification).
Filtering those out, the following other problems were found by `cd target/ecosystem_all_results/ && rg RUF200`:

I noticed in the byte-offsets refactor that the `JsonEmitter` uses one indexed column numbers for the diagnostic start and end locations but not for `edits`.
This PR changes the `JsonEmitter` to emit one-indexed column numbers for edits, as we already do for `Message::location` and `Message::end_location`.
## Open questions
~We'll need to change the LSP to subtract 1 from the columns in `_parse_fix`~
6e44fadf8a/ruff_lsp/server.py (L129-L150)
~@charliermarsh is there a way to get the ruff version in that method? If not, then I recommend adding a `version` that we increment whenever we make incompatible changes to the serialized message. We can then use it in the LSP to correctly compute the column offset.~
I'll use the presence of the `Fix::applicability` field to detect if the Ruff version uses one or zero-based column indices.
See https://github.com/charliermarsh/ruff-lsp/pull/103
