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
- rename packages to be consistent
- `swc_macros` is removed. Now macros are imported with `extern crate macro_name` instead of `extern crate swc_macros`.
- manage atoms with words.txt file
- do not reexport swc crates
- Add benchmark for parser
135ns/op on my macbook pro
- remove unused script
- Update README.md
- Make features section complete
common:
- upgrade rustc-ap crates to 297
- swc_common does not reexport sourcemap anymore
- update rustfmt to 0.99.6
simplifier:
- make some tests success when source code is equavalent
- implement fixer to fix ast broken by simplifier
- implement bit shift operators
- fix str.length
- ignore some tests
compat:
- fix `**=`
- fix es3::prop_lits
* constructor codegen
* Update string_cache to 0.7
* make swc_common not depend on sourcemap
* Remove unused dependencies
* update either to 1.5.0
* update rustc-ap crates to 297
* remove unused dependency (fnv)
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
rust-analysis chokes with `Option<Box<Expr>>` style fields.
Rls only shows a warning on the crate with that fields, but ICEs on
dependent crates.
This can be workarounded by using `Option<(Box<Expr>)>`.
Also, using multiple glob imports is bad for rls.
So this commit deglobs them.
* Remove CanIUse trait, which will be reimpplemented in future
using Visitor.
* Remove some other unused stuffs.
* Change public path of swc_common::fold::* to swc_common::*.
