2014-12-31Fix #597...NaN and Infinity were replaced in the output generation, instead of during compression. This could lead to results where `1/0` was inserted without parens leading to invalid output. The nodes are replaced in the compression step now, and the output generation returns their regular names. This should not be a problem, since they're already only constructed from the original name. Richard van Velzen

2014-07-01Evaluate "foo".length ==> 3Dan Wolff
2014-02-08Add option `keep_fargs`....By default it's `false`. Pass `true` if you need to keep unused function arguments. Close #188. Mihai Bazon

2014-01-31Fix if_return dropping the alternative. Close #413Mihai Bazon

2013-11-28Properly scope `catch` identifier when --screw-ie8...Fix #344 Mihai Bazon
2013-11-20Fix faulty compression...`String(x + 5)` is not always the same as `x + "5"`. Overlooked that. :-( Close #350 Mihai Bazon
2013-11-08Only descend twice after drop_unused if it's the same node type....Fix #345 Mihai Bazon
2013-11-06Better fix for #343...We can in fact lift sequences, but only if the operation is assignment and the left-hand side has no side effects nor property access -- that should guarantee that whatever we place before it cannot affect the sense of the assignment. Dropped contrived test case (too hard to support it now), added a more meaningful one. Mihai Bazon
2013-11-06Do not lift sequence from right-hand side of binary operation. Fix #343Mihai Bazon
2013-10-30Fix regression after e4c530240650535d1cb46569dfb013193471af05...`x * (y * z)` ==> `x * y * z` -- the better place to do this is in the compressor rather than codegen. Mihai Bazon

2013-10-29Disallow reversal where lhs has higher or equal precedence...Fixes #267 Richard van Velzen
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

2013-10-09Don'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

2013-09-19Concatenate 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
