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)
2013-03-01Drop last `default:` if it's the last branch and emptyMihai Bazon
Close #141
2013-03-01Compress boolean constants after evaluationMihai Bazon
Close #137
2013-02-19Fix compressing `do {...} while (false)`Mihai Bazon
It's not safe to transform it to {...} because the body might contain `break`. The solution could be more elaborate (detect if body contains `break`) but I don't think it's worth the trouble. Close #129
2013-02-06Force space after literal regexp when used in "instanceof" or "in"Mihai Bazon
Close #118

2013-01-17[AST_Hole] the print function can be a no-op.Mihai Bazon
2013-01-17Fix output for arrays containing undefined values.David Glasser
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.

2012-11-17retain (1,eval) as is when it's the expression of an AST_CallMihai Bazon
otherwise we change the meaning of eval from global to lexical.

2012-11-11convert x.toString() to ""+x instead of x+""Dan Wolff
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(); }
2012-11-08AST_LabelRef no longer inherits from AST_SymbolRefMihai Bazon
2012-11-08fix API breakageMihai Bazon
close #36, #38
2012-11-08optimization for if/break as first statement in a loop bodyMihai Bazon
for(...; x; ...) if (y) break; → for(...; x&&!y; ...); similarly for `while` and some combinations (i.e. the `break` appears in the `else` clause, etc.)
2012-11-07fix another small regressionMihai Bazon
we do need parens here: `new (foo.bar().baz)`, but not here: `new foo.bar.baz`
2012-11-07fix regression from 5346fb94 (shouldn't parenthesize i++ in x[i++])Mihai Bazon
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
2012-11-07parenthesize property access when it's the expression in NewMihai Bazon
