2016-06-30Fix spidermonkey AST (ESTree) export and import, Array holeskzc
Fixes: #1156 #1161 Also add test to exercise Uglify after spidermonkey export/import of itself.
2016-06-30Move OctalEscapeSequence to read_escape_charAnthony Van de Gejuchte
This should simplify and improve implementation, make it easier to implement template strings, and keep master a bit more in sync with harmony. Previous implementation wasn't broken, though the loop gave me the impression it could read infinite numbers and annoyed me a bit. It was also slightly unnecessary because the lookup involved only 3 characters.
2016-06-21Fix conditional expressions of form (x ? -1 : -1)kzc
Fixes #1154, #1153
2016-06-21Don't replace undefined, NaN and Infinity within with scopekzc
2016-06-20Keep master in sync with harmonyAnthony Van de Gejuchte
* Do not mangle when no mangle is required * Improve use_asm reset while printing code
2016-06-19Respect quote style in object literalsShrey Banga
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.

2016-06-19Don't mix strings with directives in outputAnthony Van de Gejuchte
* Don't interpret strings with escaped content as directive * Don't interpret strings after empty statement as directive * Adapt output to prevent strings being represent as directive * Introduce UGLIFY_DEBUG to allow internal testing like EXPECT_DIRECTIVE

2016-02-10Revert "using the original sourcemap as the base"sergeyv
This reverts commit ad18689d926d25c7a25b95c630c2ad05b7b5f5b5. Reason for revert: introduce issue #882 Currently, generated sourcemap contains copy of all existing mappings and adds new mappings from uglified code to original one. However, previous mapping are no longer valid and shouldn't be added.
