4a927b0d48 WIP: update README.md to reflect CLI progress 2017-04-14 15:50:47 +08:00
alexlamsl
1a56c2f31d unify CLI & API under minify() 
- refactor `screw_ie8` to `ie8`
- compact `sourceMap` options
- more stringent verification on input `options`
- toplevel shorthands
  - `ie8`
  - `keep_fnames`
  - `toplevel`
- deprecated `fromString` in `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`

281e882d27 fix reduce_vars on catch variable (#1794) 
Improved catch handling in `figure_out_scope()` means special case treatment of IE8 is no longer valid in `reset_opt_flags()`.

Also fixed recursive assignment in variable definition.

cc6aa3e5ac fix incorrect context in variable substitution (#1791) 
`AST_Node.optimize()` is context-aware, so don't cache its results to be used elsewhere.

Also fixed a few cases of AST corruption and beef up safety of `pure_getters`.

06cdb74279 improve pure_getters (#1786) 
- property access to `null` & `undefined` always has side effects
- utilise `reduce_vars` to determine safe property access
- may-be cases treated as side effects unless `unsafe`

ff289b90a9 implement delayed resolution for reduce_vars (#1788) 
Although it would be nice to enforce `AST_Node` cloning during transformation, that ship has sailed a long time ago.

We now get the assigned value when resolving `AST_SymbolRef` instead of `reset_opt_flags()`, which has the added advantage of improved compressor efficiency.
