swc_ecma_loader:
- `TsConfigResolver`: Use `baseUrl`. (#2050)
swc:
- Change type of `JscConfig.base_url` to `PathBuf`.
testing:
- Improve `NormalizedOutput::compare_to_file`.
swc_ecma_minifier:
- Implement more rules.
swc_ecma_transforms_base:
- `resolver`: Fix syntax context of catch block.
swc_ecma_transforms_optimization:
- `expr_simplifier`: Fix a bug related to `this` of call expressions.
- `dead_branch_remover`: Don't reduce switch cases if test is now known.
- `dead_branch_remover`: Don't break `&&`.
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`.
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`.
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_atoms:
- add some atoms
swc_ecma_ast:
- ast nodes for typescript
- `ClassMethod` -> `Method`, `ClassMethodKind` -> `MethodKind`
- private class method / class property
- use separate type for tagged template literals
- add `declare` field to `Decl`s
- make function body optional
swc_ecma_parser:
- rename Type to TokenContext
- support decorators
Note: error reporting for invalid decorator is not implemented yet
- merge `Config` into `Syntax`
- Use DiagnosticBuilder for error type
This is to make backtracking cheaper.
swc_ecma_transforms:
- add `strip` pass
