Using `console.error()` & `console.log()` result in inconsistent formatting across Node.js versions.
Avoid this issue by directly writing to `process.stderr` & `process.stdout` instead.
Miscellaneous

Separate flag for #203 functionality.

Have `minify()` return `Error` in `result.error` rather than throwing it.

Re-order `AST_Binary` properties to make dump more readable.

- rename `screw_ie8` to `ie8`
- rename `mangle.except` to `mangle.reserved`

Clarify docs, help and tests for --support-ie8 and screw_ie8=false
|
|
Patch by @AshleyScirra
Based on: PR #1316
Renamed the CLI debug option to --mangle-props-debug
Fixes: #1321 name collision in --mangle-props=unquoted
|
|
Also clarify documentation a bit more about using regexp as filter
|
|
|
|
For #1307.
|
|
Also removing more code within "loop" while at it.
|
|
|

catch identifier is mangled correctly for ES5 standards-compliant JS engines by default.
Unconditionally use the ie8 if/do-while workaround whether or not --screw-ie8 is enabled.
To support non-standard ie8 javascript use: uglifyjs --support-ie8
|
|
The option added in fbbaa42ee55a7f753f7cab9b1a905ccf73cf26d5 wasn't
being respected inside object literals, so quoted property names would
still be stripped out with this option.
This is mostly a corner-case, but useful when the output is passed to
something like the Closure compiler, where quoted property names can be
used to prevent mangling.

Fixes #974 and #972
|
|
Fix for #963. This allows stuff like `--define a=1 --define b=1` besides only `--define a=1,b=1`
|
|
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

--dump-spidermonkey-ast flag
|
|
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

|
|
SCOPE_IS_NEEDED is unconditionally true now. Refactored floating point literal parsing to be more in keeping with the AST class design.
