2017-04-15unify CLI & API under `minify()` (#1811)...- 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 closes #96 closes #102 closes #136 closes #166 closes #243 closes #254 closes #261 closes #311 closes #700 closes #748 closes #912 closes #1072 closes #1366 fixes #101 fixes #123 fixes #124 fixes #263 fixes #379 fixes #419 fixes #423 fixes #461 fixes #465 fixes #576 fixes #737 fixes #772 fixes #958 fixes #1036 fixes #1142 fixes #1175 fixes #1220 fixes #1223 fixes #1280 fixes #1359 fixes #1368Alex Lam S.L
2017-04-15drop `angular` (#1812)...Remove support for `@ngInject` as there are proper alternatives anyway.Alex Lam S.L
2017-04-12convert `AST_Seq` from binary tree to array (#1460)...- rename `AST_Seq` to `AST_Sequence` - raise default sequences_limit from 200 to 800Alex Lam S.L
2017-04-09fix LHS cases for NaN & friends (#1804)...`Infinity = beyond` should not become `1/0 = beyond`Alex Lam S.L
2017-04-09enhance `test/ufuzz.js` (#1803)...- `-E` to report test cases with runtime errors - favor returning expressions rather than empty return - emit a newline upon fuzzer completion to not erase the iteration count closes #1800Alex Lam S.L
2017-04-08fix a couple of bugs in `global_defs` (#1802)...- `optimize()` substituted expression - compute nested property string correctly fixes #1801 Miscellaneous - reset optimisation flags on all node typesAlex Lam S.L
2017-04-08fix `delete` corner cases (#1799)...- assignment - boolean - conditional - sequenceAlex Lam S.L
2017-04-07extend ufuzz generator (#1783)...- property access - property assignment - allow bare expression within try-block - normalise `Error` in `console.log()` - generate more unary expressions - add parenthesis to enforce precedence - adjust variable reuse/creation - add parameters to function declaration & expression - add return expression - add trivial arguments to function callAlex Lam S.L
2017-04-07fix `pure_getters` for chained property access (#1798)Alex Lam S.L
2017-04-07fix corner cases with `delete` (#1796)...`delete Infinity` returns `false` where as `delete (1/0)` returns `true`Alex Lam S.L
2017-04-07introduce "strict" to `pure_getters` (#1795)Alex Lam S.L
2017-04-07fix `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.Alex Lam S.L
2017-04-07fix 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`.Alex Lam S.L
2017-04-06improve `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`Alex Lam S.L
2017-04-05implement 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. fixes #1787Alex Lam S.L
2017-04-04optimise `do{...}while(false)` (#1785)...- better heuristics to avoid issues like #1532 - fix `TreeWalker.loopcontrol_target()` - `continue` cannot refer to `switch` blocksAlex Lam S.L
2017-04-04remove `--mangle-props` from fuzzing (#1777)...The inherently unsafe nature makes this feature unsuitable to be tested this way. fixes #1774Alex Lam S.L
2017-04-04exclude mangling of special property names (#1779)...- `null` - `true` - `false` - numeric literalsAlex Lam S.L

2017-04-01minor tweaks to fuzzer (#1751)...- remove `let` as variable name - employ `crypto.randomBytes()`Alex Lam S.L
2017-04-01implement `test/sandbox.js` (#1749)...- `test/run-tests.js` and `test/ufuzz.js` now shares the same `run_code()` and `same_stdout()` - re-enable fuzzer to generate top-level `NaN`, `Infinity` & `undefined` - attempt to show beautified output only when `run_code()` output is preservedAlex Lam S.L
2017-04-01improve compression of undefined, NaN & Infinitiy (#1748)...- migrate transformation logic from `OutputStream` to `Compressor` - always turn `undefined` into `void 0` (unless `unsafe`) - always keep `NaN` except when avoiding local variable redefinition - introduce `keep_infinity` to suppress `1/0` transform, except when avoiding local variable redefinition supersedes #1723 fixes #1730Alex Lam S.L
2017-03-31combine rules for binary boolean operations (#1744)Alex Lam S.L
2017-03-31Massive extension of the fuzzer (#1697)...Fix bug where a `throw` was generated without expression Reenable try/catch/finally and fix them up Skip serialization errors Allow function decl in other funcs but not in blocks etc Rename function to be more appropriate Fix global functions not getting certain names Make the canaries more likely to appear as expressions Add a silly rounding edge case Add a new canary, `c`, which should only ever be incremented Refactoring Fix (another) iife not actually being invoked When a statement hits recursion max return an expression instead of `;` When a expression hits recursion max also inc `c` Generate global code as well as function code Also fixes some argument juggling related bugs. No longer reduces the recursion max when generating sub functions. Generates a function arg. Add used names to var name pool while in that scope This is a little wonky, possibly a hack, but since it's synchronous code I think it's alright to do this. The alternative is to slice the varnames array and juggle them through almost all the generator functions and there are various reasons why this patch is a better alternative. Minify generated code, not beautified code. Prevents beautifier bias. Prevent unnecessary duplication Remove serialization protection because I think it got handled elsewhere Abstract toplevel code generation Add example line of running test case Add poor man options parser, and some options Reindent to 4 spaces Lower chance of `default` generation Comment example of testing a case and output improvement Enable `default` clause appearing at any clause index Removing some training wheels; dont add parens where we dont absolutely need them Support `-s1` and `-s2` to force specific statements being generated at that recursion level Add round number to output when failing. For stats and fun and profit. Solidify statement depth counting. The argument juggling is real. Renamed option to something long. -scf was ugly and probably confusing. Fix missing arguments causing `canThrow` to be truthy, generating crashing code Generate more binary nested expressions Add black and white list cli options for statement generation Allows you to explicitly require or forbid certain statements from/to being made. ``` node test/ufuzz.js --without-stmt switch,try -t 5 -r 5 -V ``` ``` node test/ufuzz.js --only-stmt ifelse,expr -t 5 -r 5 -V ``` Similar granularity for expression may be added later. There can be no comma between names; it just does a split on that arg. Trim down the binary expression generator Prevent scoping issues in nodejs by preventing certain names in global space Oh this list was incomplete? Allow bin-expr to generate assignments too. More vigilant with storing and reusing vars. Add more global builtin names Update wrapper code Also patch Function valueOfPeter van der Zee
