2015-03-16rename --prop-cache to --name-cacheMihai Bazon
... and support storing there variable names as well, to help with multiple invocations when mangling toplevel.
2015-01-04Add an option to prevent function names from being mangledRichard van Velzen
See #552. This is mostly useful for having the actual function names in traces.

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.Mihai Bazon
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).

I hereby acknowledge that figure_out_scope has become a mess.

Fix #501
2013-09-02Disallow `continue` referring to a non-IterationStatement. Fix #287Mihai Bazon
Simplifies handling of labels (their definition/references can be easily figured out at parse time, no need to do it in `figure_out_scope`).

doesn't break IE9+
2013-03-22Keep legit code working even when --screw-ie is not passed.Mihai Bazon
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
2013-03-13Support mangling toplevel namesMihai Bazon
Close #127
2013-03-02Add `--screw-ie` optionMihai Bazon
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)

2012-11-08fix API breakageMihai Bazon
close #36, #38
2012-11-07add AST_Accessor and AST_SymbolAccessor node typesMihai Bazon
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
2012-11-06add option to mangle names even if eval/with is in useMihai Bazon
(for more fair comparison to Closure compiler)
2012-11-02use a Dictionary object instead of plain object for hashesMihai Bazon
to mitigate the `__proto__` issue related to #30
2012-10-25cripple scope to make IE happy :-(Mihai Bazon
close #24
2012-10-17the `sort` option is broken anyway, removed itMihai Bazon
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.
2012-10-13fix regression from fb5c01c073d06034815d5f3b782fd11cbdf6d6f5Mihai Bazon
