2015-03-14Fix --reserved-fileMihai Bazon
2015-03-14Add property name manglerMihai Bazon
We only touch properties that are present in an object literal, or which are assigned to. Example: x = { foo: 1 }; x.bar = 2; x["baz"] = 3; x[cond ? "qwe" : "asd"] = 4; console.log(x.stuff); The names "foo", "bar", "baz", "qwe" and "asd" will be mangled, and the resulting mangled names will be used for the same properties throughout the code. The "stuff" will not be, since it's just referenced but never assigned to. This *will* break most of the code out there, but could work on carefully written code: do not use eval, do not define methods or properties by walking an array of names, etc. Also, a comprehensive list of exclusions needs to be passed, to avoid mangling properties that are standard in JavaScript, DOM, used in external libraries etc.

2015-01-27Add option to preserve/enforce string quote styleMihai Bazon
`-q 0` (default) use single or double quotes such as to minimize the number of bytes (prefers double quotes when both will do); this is the previous behavior. `-q 1` -- always use single quotes `-q 2` -- always use double quotes `-q 3` or just `-q` -- always use the original quotes. Related codegen option: `quote_style`. Close #495 Close #460 Some `yargs` guru please tell me why `uglifyjs --help` doesn't display the help string for `-q` / `--quotes`, and why it doesn't output the expected argument types anymore, like good old `optimist` did.
2015-01-05Declare boolean type for --keep-fnamesMihai Bazon
2015-01-05Support keep_fnames in compressor, and --keep-fnames. #552Mihai Bazon
Passing `--keep-fnames` will enable it both for compressor/mangler, so that function names will not be dropped (when unused) nor mangled.

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
2013-03-05Read the entire STDIN.Mike Bostock
The problem with reading synchronously from /dev/stdin is that you can get a spurious EOF when the input buffer is empty, even if more content is coming. Now STDIN is read from a loop, and only stops polling when all input has been read. This fixes #70 #85 and other errors related to parsing large files on STDIN.
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)
