2013-07-25Reverting "added option for dropping unused params"Mihai Bazon
Revert "added option for dropping unused params" (turns out we already had the `unused` option for this.) This reverts commit e54df2226f7f3887d2f850cea8caf5c0353dce00.

2013-07-18Fix output for arrays whose last element is a hole: [1,,]David Glasser
1529ab96 started to do this (by considering holes to be separate from "undefined") but it still converted [1,,] (length 2, last element hole, trailing comma) to [1,] (length 1, trailing comma) Unfortunately the test suite doesn't really make this clear: the new test here passes with or without this patch because run-tests.js beautifys the expected output (in "make_code"), which does the incorrect transformation! If you make some manual change to arrays.js to make the test fail and see the INPUT and OUTPUT, then you can see that without this fix, [1,,] -> [1,], and with this fix it stays [1,,].

2013-06-03Escape null characters as \x00Ville Lautanala
Since \0 might be mistakenly interpreted as octal if followed by a number and using literal null is in some cases interpreted as end of string, escape null as \x00.

2013-03-22Keep legit code working even when --screw-ie is not passed.Mihai Bazon
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

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)

2013-02-19Fix 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
