swc_bundler:
- Splitted from spack
swc_ecma_parser:
- Fix unexpected eof problem which occurs if log level is trace
swc_ecma_transforms:
- Fix bugs of dce pass
spack:
- Support cyclic dependencies
testing:
- Remove dependency on relative_path
swc_common:
- Span's byte positions are now self-contained and `GLOBALS` is not required while parsing.
- Changed `Comments` into a trait.
- Provide single-threaded implementation of `Comments`
- Cargo feature `tty-emiiter` (To remove tty related stuffs )
- Cargo feature `sourcemap` (To remove sourcemap for web assets)
- Removed dependency on dashmap
swc_ecma_parser:
- No duplicated comments.
- Removed dependency on once_cell and regex
- Add a test suite to visualize and test span of nodes.
swc_ecma_utils:
- Removed dependency on parser
swc:
- Remove dependency on derive_more and path-clean
- Add multi-threaded implementation of `Comments`
swc_ecmascript:
- A new crate contains `ast`, `codegen`, `parser`, `utils`, `visit`.
The commit will help
- Better testing
- Preventing regression like #785.
- **Implementing spack** (It requires access to neon api because of the plugin system)
- codegen-units = 1 for benchmarks
swc_ecma_parser:
- Add a benchmark for typescript lexer
- Remove dynamic dispatch in lexer
- Improve performance of typescript
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
`Map<T>` adds a method named `map` which is actually `Box<T>` -> `Box<T>` without reallocation.
swc_ecma_transforms:
- chain_at!(Type, passes)
This macro deeply joins path at 'Type' level.
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
- 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
