- allow immediate assignment after declaration of variable
- relax modification rule for immutable value
- fix order of visit for TreeWalker
- remove extraneous code
- rename `screw_ie8` to `ie8`
- rename `mangle.except` to `mangle.reserved`
- rename `mangle.properties.ignore_quoted` to `mangle.properties.keep_quoted`
- compact `sourceMap` options
- more stringent verification on input `options`
- toplevel shorthands
- `ie8`
- `keep_fnames`
- `toplevel`
- `warnings`
- support arrays and unquoted string values on CLI
- drop `fromString` from `minify()`
- `minify()` no longer handles any `fs` operations
- unify order of operations for `mangle_properties()` on CLI & API
- `bin/uglifyjs` used to `mangle_properties()` before even `Compressor`
- `minify()` used to `mangle_properties()` after `Compressor` but before `mangle_names()`
- both will now do `Compressor`, `mangle_names()` then `mangle_properties()`
- `options.parse` / `--parse` for parser options beyond `bare_returns`
- add `mangle.properties.builtins` to disable built-in reserved list
- disable with `--mangle-props builtins` on CLI
- `warnings` now off by default
- add `--warn` and `--verbose` on CLI
- drop `--enclose`
- drop `--export-all`
- drop `--reserved-file`
- use `--mangle reserved` instead
- drop `--reserve-domprops`
- enabled by default, disable with `--mangle-props domprops`
- drop `--prefix`
- use `--source-map base` instead
- drop `--lint`
- remove `bin/extract-props.js`
- limit exposure of internal APIs
- update documentations

This may be the case for parsing arrow functions,
as left side expressions are converted to destructuring patterns
before being converted to parameters.
`AST_Label.references` get `.initialize()` to `[]` every time after `.clone()`
So walk down the tree to pick up the cloned `AST_LoopControl` pieces and put it back together.
- Use AST_Destructuring for lhf assignment patterns
- Use AST_DefaultAssign for default assignments
- Add more checks for lhs expressions
- Add lots of testing
- Cleanup ast (e.g. remove default property)
- Fix#1402 based on a patch from @kzc
- Refine spread allowance in array destructring pattern
- Add destructuring AST tree checker
* Fixes#1147: template strings not obeying -b ascii_only true
* Allow evaluation of template expressions by adding optimizers and
walkers
* Make sure tagged templates are never changed
* Remove template tokenizer in parser, add template tokenizer in
tokenizer. It is using a brace counter to track brace position of
templates
* Add tokens `template_head` and `template_substitution` but parsing
tokens stays mostly the same
* Do not output strings anymore in AST_TemplateString, instead use
AST_TemplateSegment
* Fix parsing tagged templates, allowing multiple templates behind
as spec allows this
These changes don't influence tagged templates because raw content
may influence code execution, however they are safe to do in normal
templates:
* Allow basic string concatenation of templates where possible
* Allow custom character escape style similar to strings, except in
tagged templates
Note that expressions are still compressed in tagged templates.
Optional things that may be improved later:
* Custom quote style for templates if it doesn't have expressions.
Making it obey the quote_style option if this is the case.
- Partially reverting 91cdb93e57 and eaf3911c31 and reimplement
- Add generators support for objects and classes
- Only classes can have static methods so restrict use of it
Special thanks to @rvanvelzen and @kzc for reviewing this patch and
providing constructive feedback over and over again.
