2013-10-26Fix RHS concat (raised in #330)...When attempting to concat the left-side of the rhs, make sure the rhs is a string. Richard van Velzen
2013-10-24Fix #269...Shorten most primitives where possible. Also optimize some edge cases. Richard van Velzen
2013-10-23Fix #280...The `init` of the `ForStatement` is not a `BlockStatement` before it was descended. The descend has to happen first, and *then* the actual checks. Richard van Velzen
2013-10-22Revert #3a81f60 for now...(with it some tests break and it can generate invalid output, see issue #44) Mihai Bazon
2013-10-09wrap upMihai Bazon
2013-10-09Don't drop_unused before compression....Fix #280, #282 Mihai Bazon
2013-10-04Rename clean_getters to pure_getters; add pure_funcs.Mihai Bazon
2013-10-02add `clean_getters` compressor option (default `false`)...allows one to specify if `foo.bar` is considered to have side effects. Mihai Bazon
2013-10-02minor optimization...unlikely to help in hand-written code: (something() ? foo : bar) == foo ==> something() Mihai Bazon
2013-09-30Fix error in the output minifying `Function("return this")()`Mihai Bazon
2013-09-22More attempts to determine when addition is associative...Somebody hit me with bug reports on this. :) Refs #300 Mihai Bazon
2013-09-22Actually let's move away those monsters from the evaluate function...ev() should do a single thing — evaluate constant expressions. if that's not possible, just return the original node. it's not the best place for partial evaluation there, instead doing it in the compress functions. Mihai Bazon
2013-09-22More dirty handling of [ ... ].join() in unsafe mode...Close #300 Mihai Bazon
2013-09-22Evaluate [...].join() if possible: minor bugfix...Follow-up to 78e98d2. Dan Wolff
2013-09-19When `unsafe` is set, evaluate [...].join() if possible...Close #298 Mihai Bazon
2013-09-19Concatenate strings also on the right-hand side of an expression that cannot ......E.g. converts: a+'Hello'+'World' to a+'HelloWorld' Dan Wolff
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
2013-08-20Move support for `negate_iife` in the compressor, rather than code generator...(the code generator doesn't maintain enough context to know whether the return value is important or discarded) Fixes #272 Mihai Bazon
2013-08-18fixes #259: don't unnecessarily quote object properties when --screw-ie8Michael Ficarra
2013-08-07Don't drop unused setter argument....Fix #257 Mihai Bazon
2013-08-04Don't pretend to evaluate lambdas...Fix #255 Mihai Bazon
2013-07-25Reverting "added option for dropping unused params"...Revert "added option for dropping unused params" (turns out we already had the `unused` option for this.) This reverts commit e54df2226f7f3887d2f850cea8caf5c0353dce00. Mihai Bazon
2013-07-25added option for dropping unused paramsDusan Bartos
2013-06-07Don't swap binary ops when "use asm" is in effect....Refs #167 Mihai Bazon
2013-05-14Only compress code in `new Function` if all arguments are strings.Mihai Bazon
2013-05-14Compress code passed to `new Function` if it's a constant....Only for `--unsafe`. Close #203 Mihai Bazon
2013-05-14Fix a["1_1"]...Close #204 Mihai Bazon

2013-04-20fixes #189: use dotted member access when --screw-ie8 option givenMichael Ficarra
2013-04-03Fix typeof evaluation for regex and functionRoman Bataev
2013-03-11Disable `unsafe` by default...Close #147 Mihai Bazon
2013-03-04Fix reordering comparisons...Close #143 Mihai Bazon
2013-03-01Drop last `default:` if it's the last branch and empty...Close #141 Mihai Bazon
2013-03-01Compress boolean constants after evaluation...Close #137 Mihai Bazon
2013-02-19Fix compressing `do {...} while (false)`...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 Mihai Bazon
2013-02-06Give up evaluating (unary-prefix '-' 0)...Close #117 ------ JS, WHY YOU SUCK SO BADLY? ;-( Mihai Bazon
2013-02-06Fix handling of constants...Close #113 Mihai Bazon
2013-01-23Fix #105: property comparison to undefined is not always safeRichard Gibson
2013-01-17Handle String() with no arguments....Fix #91 Mihai Bazon
2012-12-21Optimize new Array(1, 2, 3) → [1, 2, 3]...Close #74 Mihai Bazon
2012-12-05small improvement on merging assignments into hoisted varsMihai Bazon
2012-12-05When hoisting variables, try to merge in assignments that follow.Mihai Bazon

2012-11-23fix for https://github.com/mishoo/UglifyJS/issues/474Mihai 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
