In 992b6b9fcce47ca67ecb14675f10b172ce7a99b5 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.
|
|
See #637. This does not produce the optimal result, but it does prevent the removal of non-side-effect-free code.

Because the base reference can be an member expression as well, we have to dig a bit deeper to find the leftmost base reference.
Fixes #451

`-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`.

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.

`"null"` isn't a very usable value. `JSON.parse(null)` also gives `null`, which makes this fully backwards compatible.
Closes #616

The correct format of a sourcemap is acquired
from a mozilla source map generator by calling
toJSON on this object. This patch alters the
toString function on mozilla generators to print
the format that is to spec instead of the generator's
internal representation of itself.

Previously it returned the abort node from the alternative branch. This is
not much use as it can be different from the one in the body
branch (i.e. return vs. throw) and can trick us into issues like #591.

Fix #219. Because the options were not set and `toplevel` is `false` by default, some toplevel names would sometimes not be mangled correctly.

Passing `--keep-fnames` will enable it both for compressor/mangler, so that
function names will not be dropped (when unused) nor mangled.
|
|
See #552. This is mostly useful for having the actual function names in traces.

* Creates a new SourceMapGenerator based on a SourceMapConsumer:
https://github.com/mozilla/source-map#sourcemapgeneratorfromsourcemapsourcemapconsumer
|
|
This allows usage of UglifyJS on build systems which have a flat (or non-matching relative) directory structure for source files.
|
|
See #552. This is useful for stack traces.

`\uFEFF` (ZERO WIDTH NO-BREAK SPACE) is removed when parsing, but was
un-escaped for the output when `ascii_only` was false.
When using
UglifyJS multiple times (creating packages from minified sources, for
example), this would lead to problems because the byte was removed when
parsing for the second time.

Fix max_line_len not working for JSON files

Use yargs instead of optimist.

When no arguments are given to `new Function()`, it should be treated as
a regular anonymous function (http://es5.github.io/#x15.3.2.1)

Fix #597
|
|
NaN and Infinity were replaced in the output generation, instead of
during compression. This could lead to results where `1/0` was inserted
without parens leading to invalid output.
The nodes are replaced in the compression step now, and the output
generation returns their regular names. This should not be a problem,
since they're already only constructed from the original name.
|
|
As `maybe_newline()` is only called when `might_need_semicolon` is `true`, the `max_line_len` option has no effect for files without (or with very few) semicolons (like JSON files). A simple for this problem is to use `maybe_newline()` instead of `noop` as the `newline()` function in non-beautify mode.
