2012-11-30Don't messup compressor stack while optimizing Switch...Fix #59 Mihai Bazon
2012-11-24fix #55Mihai Bazon
2012-11-23fix for https://github.com/mishoo/UglifyJS/issues/474Mihai Bazon
2012-11-18fix #51Mihai Bazon
2012-11-17retain (1,eval) as is when it's the expression of an AST_Call...otherwise we change the meaning of eval from global to lexical. Mihai Bazon
2012-11-14Add support for somewhat preserving line numbers....Usage: uglifyjs2 -b "beautify=0,preserve_line=1" /path/to/js ref #46 Richard van Velzen
2012-11-14better solution for the last test in constant switch foldingMihai Bazon
2012-11-14optimize constant switch blocks...ref. mishoo/UglifyJS#441 Mihai Bazon
2012-11-13Merge branch 'optimize_concat' of https://github.com/rvanvelzen/UglifyJS2 int...Mihai Bazon
2012-11-13don't change order in binary expressions if both operands have side effectsMihai Bazon
2012-11-12Add simple optimization for empty-string concats....ref. #43 Richard van Velzen
2012-11-12fix invalid AST produced by dropping unused variable...close #44 Mihai Bazon
2012-11-11convert x.toString() to ""+x instead of x+""...In some places this can save one byte in whitespace, e.g. after return. Example: function f(arg) { // return""+arg - no space between return and "" return arg.toString(); } Dan Wolff
2012-11-08AST_LabelRef no longer inherits from AST_SymbolRefMihai Bazon
2012-11-08fix API breakage...close #36, #38 Mihai Bazon
2012-11-08optimization for if/break as first statement in a loop body... for(...; x; ...) if (y) break; → for(...; x&&!y; ...); similarly for `while` and some combinations (i.e. the `break` appears in the `else` clause, etc.) Mihai Bazon
2012-11-07fix another small regression...we do need parens here: `new (foo.bar().baz)`, but not here: `new foo.bar.baz` Mihai Bazon
2012-11-07fix regression from 5346fb94 (shouldn't parenthesize i++ in x[i++])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
2012-11-07parenthesize property access when it's the expression in New...refs #35 Mihai Bazon
2012-11-07further fix for parens around New (refs #35)Mihai Bazon
2012-11-07parenthesize a Call expression when its parent is New...fix #35 Mihai Bazon
2012-11-07add proper parens around unary expressions...fix #34 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
2012-11-05convert `while` into `for`Mihai Bazon
2012-11-05minorMihai Bazon
2012-11-05minor optimization...for `==` or `!=` against a constant, prefer to display the constant first. should help a bit after gzip, i.e.: typeof foo=="undefined" ^^^^^^ ^^^^^^^^^^^^^ vs: "undefined"==typeof foo ^^^^^^^^^^^^^^^^^^^ (longer sequence that could repeat) idea stolen from closure. Mihai Bazon
2012-11-05print final semicolon...close #28 Mihai Bazon
2012-11-02use a Dictionary object instead of plain object for hashes...to mitigate the `__proto__` issue related to #30 Mihai Bazon
2012-11-01it's safe to negate expression in !EXP only in boolean context...#kendo Mihai Bazon
2012-11-01added unsafe_comps for negating `<=` with `>`...since it has the potential to break code, let's keep it disabled by default Mihai Bazon
2012-11-01fix compressing UnaryPrefix...only try negating the expression if the operator is `!` #kendo Mihai Bazon
2012-10-30don't move expressions containing the binary `in` operator into the `for` ini......(opera can't parse it) close #25 Mihai Bazon
2012-10-25cripple scope to make IE happy :-(...close #24 Mihai Bazon
2012-10-24fix for `if (...) return; else return ...;`...(it was assumed that the first `return` always contains a value) close #22 Mihai Bazon
2012-10-22more sequence optimizations (lift some sequences above binary/unary expressio...Mihai Bazon
2012-10-19minor fix for dropping unused definitions.... function f(x, y) { var g = function() { return h() }; var h = function() { return g() }; return x + y; } now compresses to `function f(x, y) { return x + y }` Mihai Bazon
2012-10-18more optimizations for some break/continue casesMihai Bazon
2012-10-17more small optimizations...(unlikely to help for hand-written code) Mihai Bazon
2012-10-17define aborts on AST_If: true if both branches abortMihai Bazon
2012-10-17employ a better parser for command-line arguments...to support passing commas in strings in for example: uglifyjs2 -cd TEST="'a,b'" <<EOF console.log(TEST); EOF → console.log("a,b") close #14 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
2012-10-17add `semicolons` option in the code generator (default: `true`)...pass `false` to separate statements with newlines instead of semicolons Mihai Bazon
2012-10-16fix small glitches in source map generationMihai Bazon
2012-10-13drop unused function arguments...also add test for "drop_unused" (the last one fails for now) Mihai Bazon
2012-10-13add parens to AST_Seq whose parent is AST_UnaryMihai Bazon
2012-10-13fix compressing benchmark.js (it tried to evaluate a statement)...the following code in benchmark.js triggered the issue: support.decompilation = Function( 'return (' + (function(x) { return { 'x': '' + (1 + x) + '', 'y': 0 }; }) + ')' )()(0).x === '1'; technically that could be resolved into a constant expression, but seems it's being used here for browser bugs detection :-\ Mihai Bazon
2012-10-13minorMihai Bazon
2012-10-13fix regression from fb5c01c073d06034815d5f3b782fd11cbdf6d6f5...is_digit takes a char code now, not a string Mihai Bazon
2012-10-13fix end tokens in spidermonkey ast importMihai Bazon
