Clippy on nightly produces a warning for `&t as *const _`.
This warning is spurious in this case - we know `t` is valid, because we just created it. But change it, to keep Clippy happy!
closes#2059
Breaking change:
* `--deny` / `-D` from the CLI and `error` from configuration file will
report diagnostics as severity "error".
* `--warn` / `-W` from the CLI and `warn` from configuration file will
report diagnostics as severity "warning".
## What This PR Does
- perf(lexer): use bit shifting when parsing hex, octal, and binary
integers instead of `mul_add`-ing on `f64`s. Check out the difference in
assembly generated [here](https://godbolt.org/z/zMEKaeYzh)
- perf(lexer): skip redundant utf8 check when parsing BigInts
- refactor(lexer): remove `unsafe` usage (as per @overlookmotel's
request
[here](https://github.com/oxc-project/oxc/pull/3283#issuecomment-2111814598))
- test(lexer): add numeric parsing unit tests
I don't expect this PR to have a large performance improvement, since
the most common case (`Kind::Decimal`) is not affected. We could do
this, however, by splitting `Kind::Decimal` into `Kind::DecimalFloat`
and `Kind::DecimalInt` when the lexer encounters a `.`
Allow mutable access to scopes tree and symbol table.
Closes#3189.
This completes the v1 scopes-in-traverse implementation, and provides all the primitives required to implement the missing APIs listed in https://github.com/oxc-project/oxc/discussions/3251.
Performance is abysmal, as noted in #3304, but we can fix that later on by taking `Semantic` out of the picture, or optimizing it.
Pass `&mut TraverseCtx` to `Traverse::enter_*` and `Traverse::exit_*` visitor methods. Previously was immutable `&TraverseCtx`.
This is a step towards exposing mutable scope tree + symbol table to visitors.
Move the ancestry stack into it's own type `TraverseAncestry`, and expose it via `ctx.ancestry` "namespace".
The "namespaced" way of getting parent etc (`ctx.ancestry.parent()` rather than just `ctx.parent()`) will come in useful once we introduce methods which require a `&mut TraverseCtx`.
`Traverse` use `Semantic` to construct scopes tree and expose it to visitors via `TraverseCtx`.
Currently scopes tree is immutable. Will expose it as a mutable in a follow-on.
This is extremely inefficient. Semantic does all kinds of stuff (control flow graph etc) which `Traverse` doesn't need, and `Traverse` just throws away all that work after semantic has done it. Intent here is to get a working implementation first, and then to do another pass later on to improve performance.
`oxc_semantic` populate `scope_id` fields in AST nodes as it walks the tree.
This does produce some duplication - scope IDs are stored both in the AST itself, and in `AstNode`. Will clean this up later on.
Move `BabelOptions` to Transformer. The `output.json` is a standard babel configuration. We can reuse BabelOptions to read [babel.config.json](https://babeljs.io/docs/configuration#babelconfigjson) or our configuration(maybe oxc.config.json)
The current `from_babel_options` implementation is copied from the `transform_options` in `test_case.rs`, which I'll completely reimplement next
