## Summary
This PR adds very basic support for using the line / column information
from the diagnostic message. This makes it easier to validate
diagnostics in an editor as oppose to going through the diff one
diagnostic at a time and confirming it at the location.
## Summary
This PR adds a fallback logic for `is_python_notebook` to check the
`kernelspec.language` field.
Reference implementation in VS Code:
1c31e75898/extensions/ipynb/src/deserializers.ts (L20-L22)
It's also required for the kernel to provide the `language` they're
implementing based on
https://jupyter-client.readthedocs.io/en/stable/kernels.html#kernel-specs
reference although that's for the `kernel.json` file but is also
included in the notebook metadata.
Closes: #12281
## Test Plan
Add a test case for `is_python_notebook` and include the test notebook
for round trip validation.
The test notebook contains two cells, one is JavaScript (denoted via the
`vscode.languageId` metadata) and the other is Python (no metadata). The
notebook metadata only contains `kernelspec` and the `language_info` is
absent.
I also verified that this is a valid notebook by opening it in Jupyter
Lab, VS Code and using `nbformat` validator.
## Summary
This PR adds support for VS Code specific cell metadata to consider when
collecting valid code cells.
For context, Ruff only runs on valid code cells. These are the code
cells that doesn't contain cell magics. Previously, Ruff only used the
notebook's metadata to determine whether it's a Python notebook. But, in
VS Code, a notebook's preferred language might be Python but it could
still contain code cells for other languages. This can be determined
with the `metadata.vscode.languageId` field.

This brings us one step closer to fixing #12281.
## Test Plan
Add test cases for `is_valid_python_code_cell` and an integration test
case which showcase running it end to end. The test notebook contains a
JavaScript code cell and a Python code cell.
## Summary
This PR fixes a bug in the semantic model where it would evaluate the
default parameter value in the type parameter scope. For example,
```py
def foo[T1: int](a = T1):
pass
```
Here, the `T1` in `a = T1` is undefined but Ruff doesn't flag it
(https://play.ruff.rs/ba2f7c2f-4da6-417e-aa2a-104aa63e6d5e).
The fix here is to evaluate the default parameter value in the
_enclosing_ scope instead.
## Test Plan
Add a test case which includes the above code under `F821`
(`undefined-name`) and validate the snapshot.
## Summary
See #12703. This only addresses the first bullet point, adding a space
after the comma in the suggested fix from list/tuple to string.
## Test Plan
Updated the snapshots and compared.
## Summary
This PR adds scope and definition for comprehension nodes. This includes
the following nodes:
* List comprehension
* Dictionary comprehension
* Set comprehension
* Generator expression
### Scope
Each expression here adds it's own scope with one caveat - the `iter`
expression of the first generator is part of the parent scope. For
example, in the following code snippet the `iter1` variable is evaluated
in the outer scope.
```py
[x for x in iter1]
```
> The iterable expression in the leftmost for clause is evaluated
directly in the enclosing scope and then passed as an argument to the
implicitly nested scope.
>
> Reference:
https://docs.python.org/3/reference/expressions.html#displays-for-lists-sets-and-dictionaries
There's another special case for assignment expressions:
> There is one special case: an assignment expression occurring in a
list, set or dict comprehension or in a generator expression (below
collectively referred to as “comprehensions”) binds the target in the
containing scope, honoring a nonlocal or global declaration for the
target in that scope, if one exists.
>
> Reference: https://peps.python.org/pep-0572/#scope-of-the-target
For example, in the following code snippet, the variables `a` and `b`
are available after the comprehension while `x` isn't:
```py
[a := 1 for x in range(2) if (b := 2)]
```
### Definition
Each comprehension node adds a single definition, the "target" variable
(`[_ for target in iter]`). This has been accounted for and a new
variant has been added to `DefinitionKind`.
### Type Inference
Currently, type inference is limited to a single scope. It doesn't
_enter_ in another scope to infer the types of the remaining expressions
of a node. To accommodate this, the type inference for a **scope**
requires new methods which _doesn't_ infer the type of the `iter`
expression of the leftmost outer generator (that's defined in the
enclosing scope).
The type inference for the scope region is split into two parts:
* `infer_generator_expression` (similarly for comprehensions) infers the
type of the `iter` expression of the leftmost outer generator
* `infer_generator_expression_scope` (similarly for comprehension)
infers the type of the remaining expressions except for the one
mentioned in the previous point
The type inference for the **definition** also needs to account for this
special case of leftmost generator. This is done by defining a `first`
boolean parameter which indicates whether this comprehension definition
occurs first in the enclosing expression.
## Test Plan
New test cases were added to validate multiple scenarios. Refer to the
documentation for each test case which explains what is being tested.
Make `cargo doc -p red_knot_python_semantic --document-private-items`
run warning-free. I'd still like to do this for all of ruff and start
enforcing it in CI (https://github.com/astral-sh/ruff/issues/12372) but
haven't gotten to it yet. But in the meantime I'm trying to maintain it
for at least `red_knot_python_semantic`, as it helps to ensure our doc
comments stay up to date.
A few of the comments I just removed or shortened, as their continued
relevance wasn't clear to me; please object in review if you think some
of them are important to keep!
Also remove a no-longer-needed `allow` attribute.
For type narrowing, we'll need intersections (since applying type
narrowing is just a type intersection.)
Add `IntersectionBuilder`, along with some tests for it and
`UnionBuilder` (renamed from `UnionTypeBuilder`).
We use smart builders to ensure that we always keep these types in
disjunctive normal form (DNF). That means that we never have deeply
nested trees of unions and intersections: unions flatten into unions,
intersections flatten into intersections, and intersections distribute
over unions, so the most complex tree we can ever have is a union of
intersections. We also never have a single-element union or a
single-positive-element intersection; these both just simplify to the
contained type.
Maintaining these invariants means that `UnionBuilder` doesn't
necessarily end up building a `Type::Union` (e.g. if you only add a
single type to the union, it'll just return that type instead), and
`IntersectionBuilder` doesn't necessarily build a `Type::Intersection`
(if you add a union to the intersection, we distribute the intersection
over that union, and `IntersectionBuilder` will end up returning a
`Type::Union` of intersections).
We also simplify intersections by ensuring that if a type and its
negation are both in an intersection, they simplify out. (In future this
should also respect subtyping, not just type identity, but we don't have
subtyping yet.) We do implement subtyping of `Never` as a special case
for now.
Most of this PR is unused for now until type narrowing lands; I'm just
breaking it out to reduce the review fatigue of a single massive PR.
## Summary
I'm not sure if this is useful but this is a hacky implementation to add
the filename and row / column numbers to the current Red Knot
diagnostics.
## Summary
Related to https://github.com/astral-sh/ruff-vscode/issues/571, this PR
updates the settings index builder to trace all the errors it
encountered. Without this, there's no way for user to know that
something failed and some of the capability might not work as expected.
For example, in the linked PR, the settings were invalid which means
notebooks weren't included and there were no log messages for it.
## Test Plan
Create an invalid `ruff.toml` file:
```toml
[tool.ruff]
extend-exclude = ["*.ipynb"]
```
Logs:

### Release Notes
<details>
<summary>mkdocs/mkdocs (mkdocs)</summary>
### [`v1.6.0`](https://togithub.com/mkdocs/mkdocs/releases/tag/1.6.0)
[Compare
Source](https://togithub.com/mkdocs/mkdocs/compare/1.5.3...1.6.0)
#### Local preview
- `mkdocs serve` no longer locks up the browser when more than 5 tabs
are open. This is achieved by closing the polling connection whenever a
tab becomes inactive. Background tabs will no longer auto-reload either
- that will instead happen as soon the tab is opened again. Context:
[#​3391](https://togithub.com/mkdocs/mkdocs/issues/3391)
- New flag `serve --open` to open the site in a browser.\
After the first build is finished, this flag will cause the default OS
Web browser to be opened at the home page of the local site.\
Context: [#​3500](https://togithub.com/mkdocs/mkdocs/issues/3500)
##### Drafts
> \[!warning]
> **Changed from version 1.5:**
>
> **The `exclude_docs` config was split up into two separate concepts.**
The `exclude_docs` config no longer has any special behavior for `mkdocs
serve` - it now always completely excludes the listed documents from the
site.
If you wish to use the "drafts" functionality like the `exclude_docs`
key used to do in MkDocs 1.5, please switch to the **new config key
`draft_docs`**.
See
[documentation](https://www.mkdocs.org/user-guide/configuration/#exclude_docs).
Other changes:
- Reduce warning levels when a "draft" page has a link to a non-existent
file. Context:
[#​3449](https://togithub.com/mkdocs/mkdocs/issues/3449)
#### Update to deduction of page titles
MkDocs 1.5 had a change in behavior in deducing the page titles from the
first heading. Unfortunately this could cause unescaped HTML tags or
entities to appear in edge cases.
Now tags are always fully sanitized from the title. Though it still
remains the case that
[`Page.title`](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.pages.Page.title)
is expected to contain HTML entities and is passed directly to the
themes.
Images (notably, emojis in some extensions) get preserved in the title
only through their `alt` attribute's value.
Context: [#​3564](https://togithub.com/mkdocs/mkdocs/issues/3564),
[#​3578](https://togithub.com/mkdocs/mkdocs/issues/3578)
#### Themes
- Built-in themes now also support Polish language
([#​3613](https://togithub.com/mkdocs/mkdocs/issues/3613))
##### "readthedocs" theme
- Fix: "readthedocs" theme can now correctly handle deeply nested nav
configurations (over 2 levels deep), without confusedly expanding all
sections and jumping around vertically.
([#​3464](https://togithub.com/mkdocs/mkdocs/issues/3464))
- Fix: "readthedocs" theme now shows a link to the repository (with a
generic logo) even when isn't one of the 3 known hosters.
([#​3435](https://togithub.com/mkdocs/mkdocs/issues/3435))
- "readthedocs" theme now also has translation for the word "theme" in
the footer that mistakenly always remained in English.
([#​3613](https://togithub.com/mkdocs/mkdocs/issues/3613),
[#​3625](https://togithub.com/mkdocs/mkdocs/issues/3625))
##### "mkdocs" theme
The "mkdocs" theme got a big update to a newer version of Bootstrap,
meaning a slight overhaul of styles. Colors (most notably of
admonitions) have much better contrast.
The "mkdocs" theme now has support for dark mode - both automatic (based
on the OS/browser setting) and with a manual toggle. Both of these
options are **not** enabled by default and need to be configured
explicitly.\
See `color_mode`, `user_color_mode_toggle` in
[**documentation**](https://www.mkdocs.org/user-guide/choosing-your-theme/#mkdocs).
> \[!warning]
> **Possible breaking change:**
>
> jQuery is no longer included into the "mkdocs" theme. If you were
relying on it in your scripts, you will need to separately add it first
(into mkdocs.yml) as an extra script:
>
> ```yaml
> extra_javascript:
> - https://code.jquery.com/jquery-3.7.1.min.js
> ```
>
> Or even better if the script file is copied and included from your
docs dir.
Context: [#​3493](https://togithub.com/mkdocs/mkdocs/issues/3493),
[#​3649](https://togithub.com/mkdocs/mkdocs/issues/3649)
#### Configuration
##### New "`enabled`" setting for all plugins
You may have seen some plugins take up the convention of having a
setting `enabled: false` (or usually controlled through an environment
variable) to make the plugin do nothing.
Now *every* plugin has this setting. Plugins can still *choose* to
implement this config themselves and decide how it behaves (and unless
they drop older versions of MkDocs, they still should for now), but now
there's always a fallback for every plugin.
See
[**documentation**](https://www.mkdocs.org/user-guide/configuration/#enabled-option).
Context: [#​3395](https://togithub.com/mkdocs/mkdocs/issues/3395)
#### Validation
##### Validation of hyperlinks between pages
##### Absolute links
> Historically, within Markdown, MkDocs only recognized **relative**
links that lead to another physical `*.md` document (or media file).
This is a good convention to follow because then the source pages are
also freely browsable without MkDocs, for example on GitHub. Whereas
absolute links were left unmodified (making them often not work as
expected or, more recently, warned against).
If you dislike having to always use relative links, now you can opt into
absolute links and have them work correctly.
If you set the setting `validation.links.absolute_links` to the new
value `relative_to_docs`, all Markdown links starting with `/` will be
understood as being relative to the `docs_dir` root. The links will then
be validated for correctness according to all the other rules that were
already working for relative links in prior versions of MkDocs. For the
HTML output, these links will still be turned relative so that the site
still works reliably.
So, now any document (e.g. "dir1/foo.md") can link to the document
"dir2/bar.md" as `[link](/dir2/bar.md)`, in addition to the previously
only correct way `[link](../dir2/bar.md)`.
You have to enable the setting, though. The default is still to just
skip any processing of such links.
See
[**documentation**](https://www.mkdocs.org/user-guide/configuration/#validation-of-absolute-links).
Context: [#​3485](https://togithub.com/mkdocs/mkdocs/issues/3485)
##### Absolute links within nav
Absolute links within the `nav:` config were also always skipped. It is
now possible to also validate them in the same way with
`validation.nav.absolute_links`. Though it makes a bit less sense
because then the syntax is simply redundant with the syntax that comes
without the leading slash.
##### Anchors
There is a new config setting that is recommended to enable warnings
for:
```yaml
validation:
anchors: warn
```
Example of a warning that this can produce:
```text
WARNING - Doc file 'foo/example.md' contains a link '../bar.md#some-heading', but the doc 'foo/bar.md' does not contain an anchor '#some-heading'.
```
Any of the below methods of declaring an anchor will be detected by
MkDocs:
```markdown
#### Heading producing an anchor
#### Another heading {#custom-anchor-for-heading-using-attr-list}
<a id="raw-anchor"></a>
[](){#markdown-anchor-using-attr-list}
```
Plugins and extensions that insert anchors, in order to be compatible
with this, need to be developed as treeprocessors that insert `etree`
elements as their mode of operation, rather than raw HTML which is
undetectable for this purpose.
If you as a user are dealing with falsely reported missing anchors and
there's no way to resolve this, you can choose to disable these messages
by setting this option to `ignore` (and they are at INFO level by
default anyway).
See
[**documentation**](https://www.mkdocs.org/user-guide/configuration/#validation).
Context: [#​3463](https://togithub.com/mkdocs/mkdocs/issues/3463)
Other changes:
- When the `nav` config is not specified at all, the `not_in_nav`
setting (originally added in 1.5.0) gains an additional behavior:
documents covered by `not_in_nav` will not be part of the automatically
deduced navigation. Context:
[#​3443](https://togithub.com/mkdocs/mkdocs/issues/3443)
- Fix: the `!relative` YAML tag for `markdown_extensions` (originally
added in 1.5.0) - it was broken in many typical use cases.
See
[**documentation**](https://www.mkdocs.org/user-guide/configuration/#paths-relative-to-the-current-file-or-site).
Context: [#​3466](https://togithub.com/mkdocs/mkdocs/issues/3466)
- Config validation now exits on first error, to avoid showing bizarre
secondary errors. Context:
[#​3437](https://togithub.com/mkdocs/mkdocs/issues/3437)
- MkDocs used to shorten error messages for unexpected errors such as
"file not found", but that is no longer the case, the full error message
and stack trace will be possible to see (unless the error has a proper
handler, of course). Context:
[#​3445](https://togithub.com/mkdocs/mkdocs/issues/3445)
#### Upgrades for plugin developers
##### Plugins can add multiple handlers for the same event type, at
multiple priorities
See
[`mkdocs.plugins.CombinedEvent`](https://www.mkdocs.org/dev-guide/plugins/#mkdocs.plugins.CombinedEvent)
in
[**documentation**](https://www.mkdocs.org/dev-guide/plugins/#event-priorities).
Context: [#​3448](https://togithub.com/mkdocs/mkdocs/issues/3448)
##### Enabling true generated files and expanding the
[`File`](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.File)
API
See
[**documentation**](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.File).
- There is a new pair of attributes
[`File.content_string`](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.File.content_string]/\[\`content_bytes\`]\[mkdocs.structure.files.File.content_bytes)
that becomes the official API for obtaining the content of a file and is
used by MkDocs itself.
This replaces the old approach where one had to manually read the file
located at
[`File.abs_src_path`](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.File.abs_src_path),
although that is still the primary action that these new attributes do
under the hood.
- The content of a `File` can be backed by a string and no longer has to
be a real existing file at `abs_src_path`.
It is possible to **set** the attribute `File.content_string` or
`File.content_bytes` and it will take precedence over `abs_src_path`.
Further, `abs_src_path` is no longer guaranteed to be present and can be
`None` instead. MkDocs itself still uses physical files in all cases,
but eventually plugins will appear that don't populate this attribute.
- There is a new constructor
[`File.generated()`](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.File.generated)
that should be used by plugins instead of the `File()` constructor. It
is much more convenient because one doesn't need to manually look up the
values such as `docs_dir` and `use_directory_urls`. Its signature is one
of:
```python
f = File.generated(config: MkDocsConfig, src_uri: str, content: str |
bytes)
f = File.generated(config: MkDocsConfig, src_uri: str, abs_src_path:
str)
```
This way, it is now extremely easy to add a virtual file even from a
hook:
```python
def on_files(files: Files, config: MkDocsConfig):
files.append(File.generated(config, 'fake/path.md', content="Hello,
world!"))
```
For large content it is still best to use physical files, but one no
longer needs to manipulate the path by providing a fake unused
`docs_dir`.
- There is a new attribute
[`File.generated_by`](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.File.generated_by)
that arose by convention - for generated files it should be set to the
name of the plugin (the key in the `plugins:` collection) that produced
this file. This attribute is populated automatically when using the
`File.generated()` constructor.
- It is possible to set the
[`edit_uri`](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.File.edit_uri)
attribute of a `File`, for example from a plugin or hook, to make it
different from the default (equal to `src_uri`), and this will be
reflected in the edit link of the document. This can be useful because
some pages aren't backed by a real file and are instead created
dynamically from some other source file or script. So a hook could set
the `edit_uri` to that source file or script accordingly.
- The `File` object now stores its original `src_dir`, `dest_dir`,
`use_directory_urls` values as attributes.
- Fields of `File` are computed on demand but cached. Only the three
above attributes are primary ones, and partly also
[`dest_uri`](https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.File.dest_uri).
This way, it is possible to, for example, overwrite `dest_uri` of a
`File`, and `abs_dest_path` will be calculated based on it. However you
need to clear the attribute first using `del f.abs_dest_path`, because
the values are cached.
- `File` instances are now hashable (can be used as keys of a `dict`).
Two files can no longer be considered "equal" unless it's the exact same
instance of `File`.
Other changes:
- The internal storage of `File` objects inside a `Files` object has
been reworked, so any plugins that choose to access `Files._files` will
get a deprecation warning.
- The order of `File` objects inside a `Files` collection is no longer
significant when automatically inferring the `nav`. They get forcibly
sorted according to the default alphabetic order.

[#​3463](https://togithub.com/mkdocs/mkdocs/issues/3463)
#### Hooks and debugging
- Hook files can now import adjacent \*.py files using the `import`
statement. Previously this was possible to achieve only through a
`sys.path` workaround. See the new mention in
[documentation](https://www.mkdocs.org/user-guide/configuration/#hooks).
Context: [#​3568](https://togithub.com/mkdocs/mkdocs/issues/3568)
- Verbose `-v` log shows the sequence of plugin events in more detail -
shows each invoked plugin one by one, not only the event type. Context:
[#​3444](https://togithub.com/mkdocs/mkdocs/issues/3444)
#### Deprecations
- Python 3.7 is no longer supported, Python 3.12 is officially
supported. Context:
[#​3429](https://togithub.com/mkdocs/mkdocs/issues/3429)
- The theme config file `mkdocs_theme.yml` no longer executes YAML tags.
Context: [#​3465](https://togithub.com/mkdocs/mkdocs/issues/3465)
- The plugin event `on_page_read_source` is soft-deprecated because
there is always a better alternative to it (see the new `File` API or
just `on_page_markdown`, depending on the desired interaction).
When multiple plugins/hooks apply this event handler, they trample over
each other, so now there is a warning in that case.
See
[**documentation**](https://www.mkdocs.org/dev-guide/plugins/#on_page_read_source).
Context: [#​3503](https://togithub.com/mkdocs/mkdocs/issues/3503)
##### API deprecations
- It is no longer allowed to set `File.page` to a type other than `Page`
or a subclass thereof. Context:
[#​3443](https://togithub.com/mkdocs/mkdocs/issues/3443) -
following the deprecation in version 1.5.3 and
[#​3381](https://togithub.com/mkdocs/mkdocs/issues/3381).
- `Theme._vars` is deprecated - use `theme['foo']` instead of
`theme._vars['foo']`
- `utils`: `modified_time()`, `get_html_path()`, `get_url_path()`,
`is_html_file()`, `is_template_file()` are removed. `path_to_url()` is
deprecated.
- `LiveReloadServer.watch()` no longer accepts a custom callback.
Context: [#​3429](https://togithub.com/mkdocs/mkdocs/issues/3429)
#### Misc
- The `sitemap.xml.gz` file is slightly more reproducible and no longer
changes on every build, but instead only once per day (upon a date
change). Context:
[#​3460](https://togithub.com/mkdocs/mkdocs/issues/3460)

([#​3334](https://togithub.com/mkdocs/mkdocs/issues/3334))
- Bugfix (regression in 1.5.0): In "readthedocs" theme the styling of
"breadcrumb navigation" was broken for nested pages
([#​3383](https://togithub.com/mkdocs/mkdocs/issues/3383))
- Built-in themes now also support Chinese (Traditional, Taiwan)
language
([#​3370](https://togithub.com/mkdocs/mkdocs/issues/3370))
- Plugins can now set `File.page` to their own subclass of `Page`. There
is also now a warning if `File.page` is set to anything other than a
strict subclass of `Page`.
([#​3367](https://togithub.com/mkdocs/mkdocs/issues/3367),
[#​3381](https://togithub.com/mkdocs/mkdocs/issues/3381))
Note that just instantiating a `Page` [sets the file
automatically](f94ab3f62d/mkdocs/structure/pages.py (L34)),
so care needs to be taken not to create an unneeded `Page`.
Other small improvements; see [commit
log](https://togithub.com/mkdocs/mkdocs/compare/1.5.2...1.5.3).
### [`v1.5.2`](https://togithub.com/mkdocs/mkdocs/releases/tag/1.5.2)
[Compare
Source](https://togithub.com/mkdocs/mkdocs/compare/1.5.1...1.5.2)
- Bugfix (regression in 1.5.0): Restore functionality of
`--no-livereload`.
([#​3320](https://togithub.com/mkdocs/mkdocs/issues/3320))
- Bugfix (regression in 1.5.0): The new page title detection would
sometimes be unable to drop anchorlinks - fix that.
([#​3325](https://togithub.com/mkdocs/mkdocs/issues/3325))
- Partly bring back pre-1.5 API: `extra_javascript` items will once
again be mostly strings, and only sometimes `ExtraStringValue` (when the
extra `script` functionality is used).
Plugins should be free to append strings to `config.extra_javascript`,
but when reading the values, they must still make sure to read it as
`str(value)` in case it is an `ExtraScriptValue` item. For querying the
attributes such as `.type` you need to check `isinstance` first. Static
type checking will guide you in that.

See [commit
log](https://togithub.com/mkdocs/mkdocs/compare/1.5.1...1.5.2).
### [`v1.5.1`](https://togithub.com/mkdocs/mkdocs/releases/tag/1.5.1)
[Compare
Source](https://togithub.com/mkdocs/mkdocs/compare/1.5.0...1.5.1)
- Bugfix (regression in 1.5.0): Make it possible to treat
`ExtraScriptValue` as a path. This lets some plugins still work despite
the breaking change.
- Bugfix (regression in 1.5.0): Prevent errors for special setups that
have 3 conflicting files, such as `index.html`, `index.md` *and*
`README.md`
