Make the web (development) faster.
Initial release (#45) 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
2018-11-10 11:44:35 +03:00
Documentation (#48) Use own repository for rustdoc.

swc is rust port of [babel][] and [closure compiler][].
Initial release (#45) 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

# Installation
Performance & Node binding (#84) 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
2018-12-21 10:54:36 +03:00
Currently this requires nightly version of [rust][].
