d5c651a5e5 Allow cli options to be specified in separate definitions 
Fix for #963. This allows stuff like `--define a=1 --define b=1` besides only `--define a=1,b=1`

7691bebea5 Rework has_directive 
It's now available during tree walking, i.e. walker.has_directive("use
asm"), rather than as part of the scope.  It's thus no longer necessary
to call `figure_out_scope` before codegen.  Added special bits in the
code generator to overcome the fact that it doesn't inherit from
TreeWalker.

Fix #861

d5138f7467 add --pure-funcs option 
it has the same effect as specifying `pure_funcs` in `--compressor`
option, however it's much easier to use

instead of:

    --compressor 'pure_func=["Math.floor","debug","console.logTime"]'

it's now possible:

    --compressor --pure-funcs Math.floor debug console.logTime

fixes #684

4d2f7d83af Fix handling of "use asm" when no command line flags are passed to uglifyjs. SCOPE_IS_NEEDED is unconditionally true now. Refactored floating point literal parsing to be more in keeping with the AST class design. 2015-10-07 13:10:53 -04:00

593677d2ff Add proper support for "use asm"; blocks. Disable -c optimization within "use asm"; sections and preserve floating point literals in their original form. Non-asm.js sections are optimized as before. Asm.js sections can still be mangled and minified of whitespace. No special command line flags are required. 2015-10-07 10:00:28 +02:00

ea3430102c Add property name mangler 
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.

fbbaa42ee5 Add option to preserve/enforce string quote style 
`-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.

e1f0747e4c Support keep_fnames in compressor, and --keep-fnames. #552 
Passing `--keep-fnames` will enable it both for compressor/mangler, so that
function names will not be dropped (when unused) nor mangled.
