swc_ecma_codegen:
- Fix codegen of large binary expressions.
swc_ecma_parser:
- Fix stack overflow while parsing large binary expressions.
swc_ecma_transforms:
- typescrip::strip: Fix stack overflow while handling large binary operations.
- hygiene: Fix stack overflow by migrating it to `VisitMut`.
- hygiene: Improve performance.
- fixer: Fix stack overflow by migrating it to `VisitMut`.
- resolver: Migrate to `VisitMut`.
spack:
- Optimize resolver
swc_bunder:
- Parallize merging of reexports
- Remove useless `clone`s
swc_ecma_utils:
- Migrate DropSpan to VisitMut

testing:
- Remove dependency on relative_path
swc_common:
- Span's byte positions are now self-contained and `GLOBALS` is not required while parsing.

- 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

swc_ecmascript:
- A new crate contains `ast`, `codegen`, `parser`, `utils`, `visit`.
swc_ecma_ast:
- ClassProperty.declare
swc_ecma_parser:

This pr introduces some cargo features. For `swc_common` and `swc_ecma_ast`, it introduces a feature flag `fold`.
`Fold` and `Visit` traits exist only if the feature is enabled.
For `swc_ecma_parser`, flag called `verify` is added. When disabled, we skip checking of validity of some expressions.
e.g. `{foo = bar}`
Verification is disabled by default it requires nightly compiler
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
swc_common:
- implement VisitWith for &T and [T]
swc_ecma_ast:
- fix codegen of `===`
swc_ecma_parser:
- fix parsing of array pattern
swc_ecma_transforms:
- implement es2015::destructuring
- implement es2015::computed_properties
- implement es2015::duplicate_keys
- implement es2015::parameters
- fix `InjectHelper` pass
Note that getters / setters in class are not supported yet
- Run execution tests via jest
- ignore es2016::exponentation tests
swc_ecma_transforms:
- implement es2015::block_scoped_functions
- implement tagged template literal without escape handling
- hygiene: rename to different number
- scope: handle pattern by folding children
swc_ecma_ast:
- use Str instead of String for template literal
swc_ecma_parser:
- fix lexer tests
- handle template literal correctly
template literals now have cooked field
swc_ecma_codegen:
- escape newline character and backslash ('\')
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
* 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
