2017-03-24improve error marker placement (#1644)Alex Lam S.L
For AST_UnaryPrefix, points to the operator rather than end of expression.
2017-03-24fix regression: CLI options with hyphens like -b ascii-only (#1640)kzc
fixes #1637
2017-03-21throw parse error on invalid assignments (#1627)Alex Lam S.L
fixes #1626
2017-03-10fixup for #1585 (#1589)Alex Lam S.L
As patched on `harmony`, `statement()` is the only user of `embed_tokens()` with a missing error branch. Updated test case and match up with `harmony` to facilitate future merging.

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 changesAnthony Van de Gejuchte
* 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
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.
2016-06-19Normalize error messagesAnthony Van de Gejuchte
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
2016-06-12Don't allow with statements in strict modeAnthony Van de Gejuchte
2016-06-12Throw errors in strict mode for octal stringsAnthony Van de Gejuchte
Adds a directive tracker for the parser/tokenizer to allow parsing depending on directive context.
2016-06-05Do not allow newlines in regexAnthony Van de Gejuchte
2016-05-04Handle CR line endings in comments.kzc
Fixes #1050
2016-04-16Parse comments without recursion to avoid RangeError.kzc
Fixes #993
2016-03-15Do not produce `let` as a variable name in mangle.kzc
Would previously occur in large generated functions with 21,000+ variables. Fixes #986.
2016-01-19Allow operator names as getters/settersAnthony Van de Gejuchte
Fixes #919 Fix provided by @kzc
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 ASTMihai Bazon
(will only work properly if the SM tree contains "raw" properties for Literal number nodes)
2015-11-11Rework has_directiveMihai Bazon
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
2015-11-09Fix parsing invalid inputMihai Bazon
i.e. `x = 1.xe` — because parseFloat("1.xe") returns 1, this parsed as `x = 1`. Ref #857
2015-11-09Prevent ReDoS by not using a regexp to verify floating point numbersRichard van Velzen
`parseFloat` will return `NaN` for invalid numbers anyway, which is the check used to throw the parse error. Fixes #857
2015-10-07Fix handling of "use asm" when no command line flags are passed to uglifyjs. ↵kzc
SCOPE_IS_NEEDED is unconditionally true now. Refactored floating point literal parsing to be more in keeping with the AST class design.
2015-10-07Add proper support for "use asm"; blocks. Disable -c optimization within ↵kzc
"use asm"; sections and preserve floating point literals in their original form. Non-asm.js sections are optimized as before. Asm.js sections can still be mangled and minified of whitespace. No special command line flags are required.
2015-10-06Implement shebang supportAnthony Van de Gejuchte
2015-08-27Fix bad parsing of `new new x()()` constructsRichard van Velzen
Fixes #739
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.Mihai Bazon
Fix #714
2015-05-05Only drop the BOM when it's the first character.Mihai Bazon
Close #704
2015-04-23Fix parsing strings with literal DOS newlinesMihai Bazon
(should not set newline_before) Fix #693
2015-03-18Fix parsing for U+2028 / U+2029Mihai Bazon
(they should be treated as whitespace)
2015-02-11Add filename to the JS_Parse_Error exception.Edward Casbon
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.
2015-01-27Add option to preserve/enforce string quote styleMihai Bazon
`-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.
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
2015-01-05Fix handling \r\nMihai Bazon
Close #437
2014-10-20Add option to allow return outside of functions.Mihai Bazon
Close #288
2014-04-18Always quote property names that contain non-ASCII characters.Mihai Bazon
Fix #328
2014-01-21Fix end token for conditionals. Close #404Mihai Bazon
2013-12-22Mark `yield` as reserved word. Close #375.Mihai Bazon
2013-10-30Fix parsing setters/getters (allow keywords for name).Mihai Bazon
The "key" property was always "set" or "get", which didn't make much sense. Now it'll be the actual name of the setter/getter (AST_Node), and the AST_Accessor object itself, which represents the function, won't store any name. Close #319
