Add `#[inline]` to trivial bitflags methods. Very likely this makes no difference within Oxc, as we compile with LTO enabled, but for external consumers of Oxc who don't use LTO, this will enable cross-crate inlining.
Add a conditional fix that removes `aria-hidden` from an anchor's child if there
is only a single child. This PR also fixes a false positive on hidden anchors.
It should report visible anchors with hidden content, not hidden anchors.
`VariableDeclarator` fixer will no longer delete declarations that are initialized to function expressions.
```ts
// none of these get deleted
const unusedArrow = () => {}
const unusedAnon = function() {}
const unusedNamed = function foo() {}
// matches fixer behavior for function declarations
function unusedDecl() {}
```
Exclude `scope_id` fields from JSON AST (as produced by `oxc-parser` NPM
package). I neglected to flag them `#[serde(skip)]` when I added these
fields.
This PR renames the `oxc_ast_codegen` crate to `oxc_ast_tools`, It improves the readability and organization of the codebase by giving the crate a name that better reflects its purpose and contents.
It also improves the error message in CI.
Closes#4807.
Introduce `Address`. `Address` can be obtained from a `Box<T>` and can act as a unique identifier for an AST node in arena.
NB: It will also be unique across 2 ASTs in different allocators as long as neither allocator is dropped.
Start to add dangerous suggestions for `no-unused-vars`. This PR focuses on fixing unused variable declarations.
- declarations with no references of any kind will be removed with a `FixKind` of dangerous suggestion.
- declarations with some usages will be renamed when the rule is configured with certain `"varsIgnorePattern"`s with a `FixKind` of dangerous fix.
`InjectGlobalVariables` minifier plugin was previously adding an entry to `replaced_dot_defines` each time it made a replacement, resulting in many duplicate entries if a single dot define gets replaced multiple times. Only add once for each dot define.
Adds tests for rule documentation by
1. Compiling doc markdown into HTML, which ensures docs use valid markdown syntax
2. Converts the generated HTML into JSX and parses the results with the parser, ensuring the generated HTML is valid
Has the added benefit of adding a lot of JSX test cases to the parser. I've also fixed all violations for these tests in this PR.
I got tired of seeing useless spreads on ternaries and `arr.reduce()` within my company's internal codebase so I overhauled this rule.
## Changes
- add fixer for object spreads
```js
const before = { a, ...{ b, c }, d }
const after = { a, b, c, d } // fixer does not dedupe spaces before `b`
```
- recursively check for useless clones on complex expressions. This rule now catches and auto-fixes the following cases:
```js
// ternaries when both branches create a new array or object
const obj = { ...(foo ? { a: 1 } : { b: 2 }) }
// recursive, so this can support complex cases
const arr = [ ...(foo ? a.map(fn) : bar ? Array.from(iter) : await Promise.all(bar)) ]
// reduce functions where the initial accumulator creates a new object or array
const obj = { ...(arr.reduce(fn, {}) }
```

### TL;DR
This PR introduces the ability to generate documentation for linter rules and adds new methods and metadata for rule fix capabilities.
To see what this looks like, please check out https://github.com/oxc-project/oxc-project.github.io/pull/165.

### What changed?
- Added `RuleFixMeta` to indicate rule fix capabilities
- Introduced methods `is_none` and `is_pending` in `RuleFixMeta`
- Modified `render_markdown_table` in `RuleTableSection` to accept an optional link prefix
- Created new modules for rule documentation and HTML rendering
- Updated `print_rules` function to generate markdown for rules and detailed documentation pages
### How to test?
Run the `linter-rules` task with appropriate arguments to generate the markdown table and documentation pages.
Verify the generated files for correctness and that all metadata is correctly displayed.
### Why make this change?
To enhance the project documentation and provide clear rule fix capabilities, thereby improving the developer experience and easing the integration process.
