- rename `AST_Seq` to `AST_Sequence` - raise default sequences_limit from 200 to 800
2017-03-31sort options in alphabetical order (#1743)Alex Lam S.L
They started off as functional groups I guess, but given the sheer number of options this is becoming too difficult to read.
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

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
