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`.
swc_ecma_ast:
- ClassProperty.declare
swc_ecma_parser:
- Parsing for declare class props.
- Error when parsing a private property with a declare modifier.

string_enum:
- #[derive(StringEnum)] now derives `Deserialize`
swc_ecma_ast:
- implement deserialize for ast nodes.
- change ast to make it serialized / deserialized correctly
swc_ecma_parser:
- jsx, test262, typescript tests now verify serialization and deserialization of module
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:
- 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
- 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
