Per 0262b4244c - if you're going to stop testing on 0.8, you should be testing on 0.12.
Also allow failures on unstable nodes and "older than two latest" `io.js` versions, and enable "sudo: false" which makes tests run faster.
Discarding unused function arguments affects function.length, which can lead
to some hard to debug issues. This optimization is now done only in "unsafe
mode".
Fix#121
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.
It would be nice to have access to the filename of the file that includes the code that causes a JavaScript error. This is especially handy if uglifying multiple files at once.
Only a small change is needed for this to happen as it's already available in the function that throws the error.
In 992b6b9fcc unit test broke (which I missed). This was due to undeclared variables not being side-effects free.
However, since they're really not side-effect free, just declare them in the test cases.
`-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#495Close#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.
