2017-02-24Avoid using exports when undefined (#1471)...Makes direct usage within web browser easier, even if officially unsupported.Ondřej Španěl
2016-04-12Actually limit sequence length....Fix #1038 Mihai Bazon
2016-04-07Avoid using inherited hasOwnProperty...Fix #1031 Mihai Bazon
2015-11-12Fix output for "use asm" code from SpiderMonkey AST...(will only work properly if the SM tree contains "raw" properties for Literal number nodes) Mihai Bazon
2015-11-11Rework 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 Mihai Bazon
2015-10-07Fix handling of "use asm" when no command line flags are passed to uglifyjs. ...kzc
2015-09-24No longer use `vm` to load code....Improves performance 2x on node > 0.10. Ref #636 Mihai Bazon
2015-09-24Fix wrap_commonjs to include code first...(code could have directives, i.e. "use strict") Mihai Bazon
2015-01-27Add 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.
