2017-05-14fix bugs with getter/setter (#1926)...- `reduce_vars` - `side_effects` - property access for object - `AST_SymbolAccessor` as key names enhance `test/ufuzz.js` - add object getter & setter - property assignment to setter - avoid infinite recursion in setter - fix & adjust assignment operators - 50% `=` - 25% `+=` - 2.5% each for the rest - avoid "Invalid array length" - fix `console.log()` - bypass getter - curb recursive reference - deprecate `-E`, always report runtime errorsAlex Lam S.L
2017-05-12remove support for `const` (#1910)...As this is not part of ES5.Alex Lam S.L
2017-04-23improve parser under "use strict" (#1836)...- `const` without value - `delete` of expression - redefining `arguments` or `eval` extend `test/ufuzz.js` - optionally generate "use strict" - improve handling of test cases with syntax errors - group IIFE generation - generate bare anonymous functions - workaround `console.log()` for `new function()` - generate expressions with `this` fixes #1810Alex Lam S.L
2017-04-19fix parser bugs & CLI reporting (#1827)...fixes #1825Alex Lam S.L
2017-04-15unify CLI & API under `minify()` (#1811)...- rename `screw_ie8` to `ie8` - rename `mangle.except` to `mangle.reserved` - rename `mangle.properties.ignore_quoted` to `mangle.properties.keep_quoted` - compact `sourceMap` options - more stringent verification on input `options` - toplevel shorthands - `ie8` - `keep_fnames` - `toplevel` - `warnings` - support arrays and unquoted string values on CLI - drop `fromString` from `minify()` - `minify()` no longer handles any `fs` operations - unify order of operations for `mangle_properties()` on CLI & API - `bin/uglifyjs` used to `mangle_properties()` before even `Compressor` - `minify()` used to `mangle_properties()` after `Compressor` but before `mangle_names()` - both will now do `Compressor`, `mangle_names()` then `mangle_properties()` - `options.parse` / `--parse` for parser options beyond `bare_returns` - add `mangle.properties.builtins` to disable built-in reserved list - disable with `--mangle-props builtins` on CLI - `warnings` now off by default - add `--warn` and `--verbose` on CLI - drop `--enclose` - drop `--export-all` - drop `--reserved-file` - use `--mangle reserved` instead - drop `--reserve-domprops` - enabled by default, disable with `--mangle-props domprops` - drop `--prefix` - use `--source-map base` instead - drop `--lint` - remove `bin/extract-props.js` - limit exposure of internal APIs - update documentations closes #96 closes #102 closes #136 closes #166 closes #243 closes #254 closes #261 closes #311 closes #700 closes #748 closes #912 closes #1072 closes #1366 fixes #101 fixes #123 fixes #124 fixes #263 fixes #379 fixes #419 fixes #423 fixes #461 fixes #465 fixes #576 fixes #737 fixes #772 fixes #958 fixes #1036 fixes #1142 fixes #1175 fixes #1220 fixes #1223 fixes #1280 fixes #1359 fixes #1368Alex Lam S.L

2017-03-31sort options in alphabetical order (#1743)...They started off as functional groups I guess, but given the sheer number of options this is becoming too difficult to read.Alex Lam S.L
2017-03-24improve error marker placement (#1644)...For AST_UnaryPrefix, points to the operator rather than end of expression.Alex Lam S.L
2017-03-24fix regression: CLI options with hyphens like -b ascii-only (#1640)...fixes #1637kzc

2016-07-21Legacy octal integer strict mode fixesAnthony Van de Gejuchte
2016-07-15Fix error style for regex errorsAnthony Van de Gejuchte
2016-06-30Various LineTerminator changes...* Escaped newlines should also produce SyntaxError * Fix multiline comment parsing and add tests * Adapt makePredicate to handle \u2028 and \u2029 * Move up nlb check in regex so it's checked before any escape handling * Change error messages to conform ecma standard * Find_eol not recornizing \u2028 and \u2029 as line terminator * Remove \u180e as it is removed in unicode 6.3.0 from the category zs Anthony Van de Gejuchte
2016-06-30Move OctalEscapeSequence to read_escape_char...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. Anthony Van de Gejuchte
2016-06-19Normalize error messagesAnthony Van de Gejuchte
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
2016-06-12Don't allow with statements in strict modeAnthony Van de Gejuchte
2016-06-12Throw errors in strict mode for octal strings...Adds a directive tracker for the parser/tokenizer to allow parsing depending on directive context. Anthony Van de Gejuchte
2016-06-05Do not allow newlines in regexAnthony Van de Gejuchte
2016-05-04Handle CR line endings in comments....Fixes #1050 kzc
2016-04-16Parse comments without recursion to avoid RangeError....Fixes #993 kzc
2016-03-15Do not produce `let` as a variable name in mangle....Would previously occur in large generated functions with 21,000+ variables. Fixes #986. kzc
2016-01-19Allow operator names as getters/setters...Fixes #919 Fix provided by @kzc Anthony Van de Gejuchte
2015-12-27Fix ch that could contain other newline charactersAnthony Van de Gejuchte
2015-12-26Do not allow newlines in string literalsAnthony Van de Gejuchte
2015-12-17Semicolon after do...while statement is optionalAnthony 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
2015-11-09Fix parsing invalid input...i.e. `x = 1.xe` — because parseFloat("1.xe") returns 1, this parsed as `x = 1`. Ref #857 Mihai Bazon
2015-11-09Prevent ReDoS by not using a regexp to verify floating point numbers...`parseFloat` will return `NaN` for invalid numbers anyway, which is the check used to throw the parse error. Fixes #857 Richard van Velzen
2015-10-07Fix handling of "use asm" when no command line flags are passed to uglifyjs. ...kzc
2015-10-07Add proper support for "use asm"; blocks. Disable -c optimization within "use...kzc
2015-10-06Implement shebang supportAnthony Van de Gejuchte
2015-08-27Fix bad parsing of `new new x()()` constructs...Fixes #739 Richard van Velzen
2015-07-29Re-use the caught exception's error message in the parse error call.Chris Cowan
2015-07-29Give a good error message if an invalid regular expression is found.Chris Cowan
2015-05-20Treat \uFEFF as whitespace....Fix #714 Mihai Bazon
2015-05-05Only drop the BOM when it's the first character....Close #704 Mihai Bazon
2015-04-23Fix parsing strings with literal DOS newlines...(should not set newline_before) Fix #693 Mihai Bazon
2015-03-18Fix parsing for U+2028 / U+2029...(they should be treated as whitespace) Mihai Bazon
2015-02-11Add filename to the JS_Parse_Error exception....It would be nice to have access to the filename of the file that includes the code that causes a JavaScript error. This is especially handy if uglifying multiple files at once. Only a small change is needed for this to happen as it's already available in the function that throws the error.Edward Casbon
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
2015-01-20Add unicode digit parsing supportAnthony Van de Gejuchte
2015-01-20Update unicode letterAnthony Van de Gejuchte
2015-01-06Track ending lines/columns; fix end locations in Mozilla AST.Ingvar Stepanyan
