- `hygiene`: Keep the name of class expressions. (#1507)
swc_ecma_transforms_typescript:
- Allow a namespace and a class to have the same name. (#1515)
swc:
- Disable `tsx` if the ext of a file is ts.
swc_common:
- update rustc-ap crates to v313
swc_ecma_ast:
- use bool instead of Option<Span>
swc_ecma_parser:
- remove LexerInput
- use uncons_while
- assert only on debug mode
- use Visit instead of Fold while verifying
- replace debug! with trace!
- disable logging while benchmarking
- drop slog
swc_ecma_transforms:
- classes: fold Decl instead of Stmt
swc:
- add nodejs binding
ecma_transforms:
- implement es2015::instanceof
- implement es2015::typeof_symbol
- implement inline_globals pass
ecma_parser:
- `PResult<T>` is now `Result<T, ()>` and `Err(())` means that an error is emitted.
- add docs
common:
- rename `Folder` to `Fold`
- folder.then()
- impl Fold for Box<F>
- impl Fold<T> for &mut F where F: Fold<T>
transforms:
- make Simplifier private
- organize compat
codegen:
- use `Mark` to avoid deoptimization
swc:
- upgrade rayon and use global thread pool instead
* `struct Expr` + `enum ExprKind` -> `enum Expr`
`Expr` / `ExprKind` approach does not work well with recursive
processing based on the type system because we can't access common
fields like span while processing child node like `MemberExpr`.
As ast processing is inherently recursive, we should use a
recursive-friendly approach.
* `#[derive(FromVariants)]`
It creates lots of `From<T>` to help using ast enums as a real sum type.
* `#[derive(Spanned)]`
Inspired by https://docs.rs/syn/0.12.13/syn/spanned/trait.Spanned.html
It does not handle attributes yet.
* Parser is not updated yet.
- Make rls happy.
- Some minor parser error improvements.
- Add reference files for ecmascript parser errors.
- Improve error message of import/export used outside of a module
- Parser and lexer for lastest ecma spec https://tc39.github.io/ecma262
- Lexer is currently very inefficient
- Use https://github.com/tc39/test262-parser-tests/ for testing.
- Implement proc-macro based ast folder and assert_eq_ignore_span! based on it.
- Some utilities for proc macro at /macros/common
