2017-01-26fix mangling collision with keep_fnames (#1431)...* fix mangling collision with keep_fnames fixes #1423 * pass mangle options to figure_out_scope() bring command-line in line with minify() Alex Lam S.L
2017-01-26augment evaluate to extract within objects (#1425)...- gated by `unsafe` - replaces previous optimisation specific to String.length - "123"[0] => 1 - [1, 2, 3][0] => 1 - [1, 2, 3].length => 3 - does not apply to objects with overridden prototype functionsAlex Lam S.L
2017-01-19add missing LHS cases which global_defs should avoidalexlamsl
2016-10-23fix uses_arguments handling (broken since 6605d1578351)...Using the symbol declaration tracking of UglifyJS doesn't make sense here anyway, `arguments` always comes from something in the current scope. fixes #1299 Jann Horn

2016-07-15Fix mangle with option keep_fnames=true for Safari....Fixes: #1202 kzc
2016-06-30Enable --screw-ie8 by default....catch identifier is mangled correctly for ES5 standards-compliant JS engines by default. Unconditionally use the ie8 if/do-while workaround whether or not --screw-ie8 is enabled. To support non-standard ie8 javascript use: uglifyjs --support-ie8 kzc
2016-03-28Speedup `unused` compress option for already minified code...Fixes: #321 #917 #1022 kzc

2016-01-19Mark vars with /** @const */ pragma as consts so they can be eliminated....Fixes older browser support for consts and allows more flexibility in dead code removal. Samuel Reed
2016-01-14Never mangle arguments and keep them in their scope...Fixes #892 Helped-by: kzc Anthony Van de Gejuchte
2015-11-12Build label def/refs info when figuring out scope...Fix #862 Mihai Bazon
2015-11-11Rework has_directive...It's now available during tree walking, i.e. walker.has_directive("use asm"), rather than as part of the scope. It's thus no longer necessary to call `figure_out_scope` before codegen. Added special bits in the code generator to overcome the fact that it doesn't inherit from TreeWalker. Fix #861 Mihai Bazon
2015-10-07Add proper support for "use asm"; blocks. Disable -c optimization within "use...kzc
2015-03-16rename --prop-cache to --name-cache...... and support storing there variable names as well, to help with multiple invocations when mangling toplevel. Mihai Bazon
2015-01-04Add an option to prevent function names from being mangled...See #552. This is mostly useful for having the actual function names in traces. Richard van Velzen

2014-09-12Don't warn for an unreferenced exception symbol in a catch block.Arnavion
2014-02-14Mangle name of exception when --screw-ie8. Fix #430....The effect of not mangling it was visible only with --screw-ie8 (otherwise the names would be mangled exactly because they leaked into the parent scope). Mihai Bazon

2013-12-05AST_Catch shouldn't really inherit from AST_Scope. Fix #363...I hereby acknowledge that figure_out_scope has become a mess. Mihai Bazon

2013-09-02Disallow `continue` referring to a non-IterationStatement. Fix #287...Simplifies handling of labels (their definition/references can be easily figured out at parse time, no need to do it in `figure_out_scope`). Mihai Bazon

2013-03-22Keep legit code working even when --screw-ie is not passed....Previously: Without `--screw-ie`, UglifyJS would always leak names of function expressions into the containing scope, as if they were function declarations. That was to emulate IE<9 behavior. Code relying on this IE bug would continue to work properly after mangling, although it would only work in IE (since other engines don't share the bug). Sometimes this broke legitimage code (see #153 and #155). With `--screw-ie` the names would not be leaked into the current scope, working properly in legit cases; but still it broke legit code when running in IE<9 (see #24). Currently: Regardless of the `--screw-ie` setting, the names will not be leaked. Code relying on the IE bug will not work properly after mangling. <evil laughter here> Without `--screw-ie`: a hack has been added to the mangler to avoid using the same name for a function expression and some other variable in the same scope. This keeps legit code working, at the (negligible, indeed) cost of one more identifier. With `--screw-ie` you allow the mangler to name function expressions with the same identifier as another variable in scope. After mangling code might break in IE<9. Oh man, the commit message is longer than the patch. Fix #153, #155 Mihai Bazon
2013-03-13Support mangling toplevel names...Close #127 Mihai Bazon
2013-03-02Add `--screw-ie` option...For now the implication is that UglifyJS will not leak a function expression's name in the surrounding scope (IE < 9 does that). (ref. mishoo/UglifyJS#485) Mihai Bazon

2012-11-08fix API breakage...close #36, #38 Mihai Bazon
2012-11-07add AST_Accessor and AST_SymbolAccessor node types...AST_Accessor will represent the function for a setter or getter. Since they are not mangleable, and they should not introduce a name in scope, we have a new node for their name (AST_SymbolAccessor) which doesn't inherit from AST_SymbolDeclaration. fix #37 Mihai Bazon
2012-11-06add option to mangle names even if eval/with is in use...(for more fair comparison to Closure compiler) Mihai Bazon
2012-11-02use a Dictionary object instead of plain object for hashes...to mitigate the `__proto__` issue related to #30 Mihai Bazon
2012-10-25cripple scope to make IE happy :-(...close #24 Mihai Bazon
2012-10-17the `sort` option is broken anyway, removed it...we need to mangle names from outermost to innermost scope; mangling names from inner scopes before we got to the outer scope won't work correctly, therefore sorting doesn't make sense. Mihai Bazon
2012-10-13fix regression from fb5c01c073d06034815d5f3b782fd11cbdf6d6f5...is_digit takes a char code now, not a string Mihai Bazon
