2014-10-20Add option to allow return outside of functions....Close #288 Mihai Bazon
2014-04-18Always quote property names that contain non-ASCII characters....Fix #328 Mihai Bazon
2014-01-21Fix end token for conditionals. Close #404Mihai Bazon
2013-12-22Mark `yield` as reserved word. Close #375.Mihai Bazon
2013-10-30Fix parsing setters/getters (allow keywords for name)....The "key" property was always "set" or "get", which didn't make much sense. Now it'll be the actual name of the setter/getter (AST_Node), and the AST_Accessor object itself, which represents the function, won't store any name. Close #319 Mihai Bazon

2013-10-03Only allow identifier start characters at the beginning of identifiers....Without this fix, the following source: x = {"\u200c": 42}; would incorrectly be converted into a quoteless key. But while \u200c is allowed to be in identifiers, it cannot be at the beginning, as per ES5. (For example, the SockJS client library doesn't work under uglify starting with d9ad3c7c.) David Glasser
2013-09-06Support HTML5 comment syntax (enabled by default!)...See http://javascript.spec.whatwg.org/#comment-syntax https://github.com/mishoo/UglifyJS/issues/503 https://github.com/marijnh/acorn/issues/62 Mihai Bazon
2013-09-02Fix names.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
2013-09-02Better fix for #286Mihai Bazon
2013-09-02Fix parsing `a.case /= 1`...Close #286 Mihai Bazon
2013-09-02Fix parsing regexp after unary-prefix operator...++/x/.y Fix #284 Mihai Bazon
2013-07-15Revert previous patch, it was no good.Mihai Bazon
2013-07-15Add "position" option to parser, to specify initial pos/line/col...(for parsing embedded scripts) Mihai Bazon
2013-07-12Fix typo....Close #239 Mihai Bazon
2013-05-15Add `--expr`, an option to parse a single expression (suitable for JSON)Mihai Bazon
2013-05-14Fix a["1_1"]...Close #204 Mihai Bazon
2013-05-09Fix is_assignable...(not likely to be noticed, it's only used in `strict` parse mode) Mihai Bazon
2013-05-08Fix property names...Close #199 Mihai Bazon
2013-05-07Fixed dot properties not optimizing unicode identifiers. Signed-off-by: Justi...Justin Lau
2013-03-24Don't print the warning on parse error, just throw a JS_Parse_Error....Fix #159 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
2013-02-01Fix end token for Assign nodesMihai Bazon
2013-01-17Fix output for arrays containing undefined values....1b6bcca7 was a first attempt at this. That commit made Uglify stop replacing holes with undefined, but instead it started replacing undefined with holes. This is slightly problematic, because there is a difference between a hole and an undefined value. More problematically, it changed [1,undefined] to [1,] which generally doesn't even parse as a hole (just as a trailing comma), so it didn't even preserve the length of the array! Instead, parse holes as their own special AST node which prints invisibly. David Glasser
2012-12-22Accept string or number as name of an accessor....[not sure I'm happy about this fix] Reference mishoo/UglifyJS#478 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
2012-10-13minorMihai Bazon
2012-10-12use AST_Lambda for object setters/getters...so that the optimization that drops the name if unused doesn't apply. close #12 Mihai Bazon
2012-10-11fix pos in syntax error exceptionMihai Bazon
2012-10-11stealing more hacks from acorn in the name of speedMihai Bazon
2012-10-11using makeComparator from acorn to generate functions that tests whether a...string is keyword, reserved etc. speeds up the parser a bit, though not spectacular.. still far from acorn. Mihai Bazon
2012-10-11cleanup...- use prototype-less objects where feasible (minor speed improvement) - get rid of HOP Mihai Bazon
2012-10-09make `--comments` keep @cc_on tooMihai Bazon
2012-10-09added $propdoc to AST nodes and some cleanups...hopefully we can make the AST documentation self-generating Mihai Bazon
2012-10-04removed some unused variablesMihai Bazon
2012-10-03more cleanup (dropped AST_SwitchBlock)Mihai Bazon
2012-10-02line numbers start at 1Mihai Bazon
2012-10-02"use strict";Mihai Bazon
2012-10-02add AST_SymbolConst for names defined with `const`Mihai Bazon
2012-09-25discard all \uFEFF characters (https://github.com/mishoo/UglifyJS/issues/462)Mihai Bazon
2012-09-21log filename in parse errors / compressor warningsMihai Bazon
2012-09-21better support for multiple input files:...- use a single AST_Toplevel node for all files - keep original source filename in the tokens Mihai Bazon
2012-09-18support for directivesMihai Bazon
2012-09-14more optimizations that v1 does and some cleanups...- a = a + x ==> a+=x - joining consecutive var statements (hoisting is not always desirable) - x == false ==> x == 0, x != true ==> x != 1 - x, x ==> x; x = exp(), x ==> x = exp() - discarding useless break-s Mihai Bazon
2012-09-05cleaned up usage of AST_BlockStatement...The following nodes were instances of AST_BlockStatement: AST_Scope, AST_SwitchBlock, AST_SwitchBranch. Also, AST_Try, AST_Catch, AST_Finally were having a body instanceof AST_BlockStatement. Overloading the meaning of AST_BlockStatement this way turned out to be a mess; we now have an AST_Block class that is the base class for things having a block of statements (might or might not be bracketed). The `this.body` of AST_Scope, AST_Try, AST_Catch, AST_Finally is now an array of statements (as they inherit from AST_Block). Avoiding calling superclass's _walk function in walkers (turns out we walked a node multiple times). Mihai Bazon
2012-09-03an AST_If is too a StatementWithBodyMihai Bazon
2012-09-03a LabeledStatement should be in fact a StatementWithBody...This fixes output for: if (foo) { moo: if (bar) { break moo; } } else { baz(); } (the labeled statement must be outputted inside brackets) Mihai Bazon
2012-09-03Reverting "minor perf. improvements"...Revert "minor perf. improvements" This reverts commit 24bfd55a22afd791d4a97694641831cfbd27fb14. broke the parser somehow; too early to optimize, let's get the other stuff running. Mihai Bazon
2012-09-02minor perf. improvementsMihai Bazon
