2017-03-08plan B for IE8 do-while semi-colon fix (#1572)...- omitting trailing semi-colon in do-while breaks non-browser parser, e.g. uglify-js 1.x - trailing semi-colon only breaks IE8 if followed by `else` or `while` - always use braces in do-while body to workaround 2nd case with no size loss in compression fixes #1568Alex Lam S.L
2017-03-06suppress semicolons after do/while (#1556)...- unless both `beautify` & `screw-ie8` are enabled - deprecate workaround for if-do-while-else fixes #186Alex Lam S.L
2017-03-05fix handling of shebang and preamble (#1545)...fixes #1332Alex Lam S.L
2017-02-21clean up `max_line_len`...- never exceed specified limit - otherwise warning is shown - enabled only for final output closes #1496 alexlamsl
2017-02-21remove extraneous spaces between ++/+/--/-...fixes #1377 closes #1488 alexlamsl
2017-02-21improve `--beautify bracketize`...reduce whitespaces from if-else statements fixes #1482 closes #1483 alexlamsl
2017-02-21clean up `negate_iife`...- remove extra tree scanning phase for `negate_iife` - `negate_iife` now only deals with the narrowest form, i.e. IIFE sitting directly under `AST_SimpleStatement` - `booleans`, `conditionals` etc. will now take care the rest via more accurate accounting - `a(); void b();` => `a(); b();` fixes #1288 closes #1451 alexlamsl
2016-11-29Do not overwrite options.comments + cleanupAnthony Van de Gejuchte
2016-10-23Don't filter shebangs when using the 'some' comment filter...Also clarify documentation a bit more about using regexp as filter Anthony Van de Gejuchte
2016-10-06Remove console.log and add extra test caseRichard van Velzen
2016-10-06Add an option to wrap IIFEs in parenthesis...For #1307. Richard van Velzen
2016-09-06Make all comment options in cli available in js api...Also removing more code within "loop" while at it. Anthony Van de Gejuchte
2016-08-17Fix negate_iife transform to return a correct tree for nested IIFEs...Fix for #1256, partially reverts d854523783b4 Richard van Velzen
2016-08-17Fix negate_iife regression #1254kzc
2016-08-14Fix unneeded parens around unary args in new expression.kzc
2016-06-30Enable --screw-ie8 by default....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 kzc
2016-06-20Keep master in sync with harmony... * Do not mangle when no mangle is required * Improve use_asm reset while printing code Anthony Van de Gejuchte
2016-06-19Respect quote style in object literals...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. Shrey Banga
2016-06-19Don't mix strings with directives in output... * 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 Anthony Van de Gejuchte
2016-06-12Re-add parens after new expression in beautify modeAnthony Van de Gejuchte
2016-06-12Stop dropping args in new expressionsAnthony Van de Gejuchte
2016-06-12Escape null characters as \0 unless followed by 0-7.David Bau
2016-06-08Fix uglify attempting to rewrite invalid new expressionsAnthony Van de Gejuchte
2016-05-04Retain comments before AST_Constants during mangle.kzc
2016-03-24Escape all ASCII control characters within strings when using ascii_only....Fixes #1017. Tab characters within strings are now output as `\t` in all output modes. kzc
2016-03-14Fix: Uglified Number.prototype functions on big numbersphilippsimon
2016-01-19Add some tests for comment-filters through api...Also never bother comment options to filter comment5/shebang comments as they have their custom filter. Anthony Van de Gejuchte
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
2015-10-28Allow specification beautify options in tests...Caught an error in #847 as well - `output` wasn't passed anywhere which led to an exception. `options` was available though. Richard van Velzen
2015-10-27fixes #845: \v escaping should be restricted to "screw_ie8" modeMichael Ficarra
2015-10-20Fix #836Fábio Santos

2015-10-07Fix handling of "use asm" when no command line flags are passed to uglifyjs. ...kzc

2015-10-06Implement shebang supportAnthony Van de Gejuchte
2015-07-30Fix semicolon printing when restricting max line length...Fixes #755 Richard van Velzen
2015-05-04Fix blank lines in the output....The issue was more obvious when max_line_len has a small value, rather than the default 32K characters. A blank line showed up after most statements. 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. Mihai Bazon
2015-01-26Keep single line comments after nlb, after nlb...Fixes #583 Anthony Van de Gejuchte
2015-01-04Fix #556...`\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. Richard van Velzen
2015-01-04Merge pull request #592 from micschro/patch-1...Fix max_line_len not working for JSON filesRichard van Velzen
2014-12-31Fix #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. Richard van Velzen
2014-12-17Fix max_line_len not working for JSON files...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.micschro
2014-07-18Fix parens for AST_Undefined...Do the same as for AST_Unary, since we output undefined as `void 0`. Reported at https://github.com/mishoo/UglifyJS2/issues/338#issuecomment-48858341 Mihai Bazon
2014-07-01Check for the case an AST_For's init is an EmptyStatement...(lame fix for #503) Mihai Bazon
2014-04-27Actually, even better. #475...- also handle x = + ++y, x = - --y; - don't use parens, a space suffices. Mihai Bazon
