2012-11-24fix #55Mihai Bazon
2012-11-08AST_LabelRef no longer inherits from AST_SymbolRefMihai Bazon
2012-11-07add AST_Accessor and AST_SymbolAccessor node types...AST_Accessor will represent the function for a setter or getter. Since they are not mangleable, and they should not introduce a name in scope, we have a new node for their name (AST_SymbolAccessor) which doesn't inherit from AST_SymbolDeclaration. fix #37 Mihai Bazon
2012-10-22more sequence optimizations (lift some sequences above binary/unary expressio...Mihai Bazon
2012-10-18more optimizations for some break/continue casesMihai Bazon
2012-10-12remove the $self hack...operations are destructive anyway, so there's no point to clone the nodes in the transformer. speed++ Mihai Bazon
2012-10-12fix in_boolean_context() (two tests were broken)Mihai Bazon
2012-10-11cleanup...- use prototype-less objects where feasible (minor speed improvement) - get rid of HOP Mihai Bazon
2012-10-10fix node nameMihai Bazon
2012-10-10seems cleaner if AST_Label doesn't inherit from AST_SymbolDeclarationMihai Bazon
2012-10-10small improvements in wrap_commonjs:...- use MAP.splice instead of a BlockStatement to inject code (avoids some warnings in the linter) - use the original symbol in exports, so that we get the proper source mapping Mihai Bazon
2012-10-09add AST_Infinity nodeMihai Bazon
2012-10-09added $propdoc to AST nodes and some cleanups...hopefully we can make the AST documentation self-generating Mihai Bazon
2012-10-09minor AST cleanup (AST_BlockStatement may inherit from AST_Block)Mihai Bazon
2012-10-09add `--ast-help`...displays a rather cruel description of the AST classes, derived directly from the node definitions. Mihai Bazon
2012-10-08added --self to easily get a browser-runnable version of UglifyJSMihai Bazon
2012-10-03more cleanup (dropped AST_SwitchBlock)Mihai Bazon
2012-10-03AST cleanup (dropped AST_StatementBase)Mihai Bazon
2012-10-02"use strict";Mihai Bazon
2012-10-02add AST_SymbolConst for names defined with `const`Mihai Bazon
2012-09-28minorMihai Bazon
2012-09-26checkpoint (refactoring, WIP)Mihai Bazon
2012-09-23properly drop mutually-referring declarations that are not otherwise...referenced and have no side effects Mihai Bazon
2012-09-21better support for multiple input files:...- use a single AST_Toplevel node for all files - keep original source filename in the tokens Mihai Bazon
2012-09-18fixed label scope/manglingMihai Bazon
2012-09-18support for directivesMihai Bazon
2012-09-18added AST_NaN (output as 0/0)Mihai Bazon
2012-09-15figure out label targetsMihai Bazon
2012-09-14more optimizations that v1 does and some cleanups...- a = a + x ==> a+=x - joining consecutive var statements (hoisting is not always desirable) - x == false ==> x == 0, x != true ==> x != 1 - x, x ==> x; x = exp(), x ==> x = exp() - discarding useless break-s Mihai Bazon
2012-09-11fixed some mess with symbols/scope...- all symbols now have a `thedef` property which is a SymbolDef object, instead of the `uniq` that we had before (pointing to the first occurrence of the name as declaration). - for undeclared symbols we still create a SymbolDef object in the toplevel scope but mark it "undeclared" - we can now call figure_out_scope after squeezing, which is useful in order not to mangle names that were dropped by the squeezer Mihai Bazon
2012-09-07checkpointMihai Bazon
2012-09-07fixed tests (need to drop the toplevel block in "expected" if it's a single s...Mihai Bazon
2012-09-05cleaned up usage of AST_BlockStatement...The following nodes were instances of AST_BlockStatement: AST_Scope, AST_SwitchBlock, AST_SwitchBranch. Also, AST_Try, AST_Catch, AST_Finally were having a body instanceof AST_BlockStatement. Overloading the meaning of AST_BlockStatement this way turned out to be a mess; we now have an AST_Block class that is the base class for things having a block of statements (might or might not be bracketed). The `this.body` of AST_Scope, AST_Try, AST_Catch, AST_Finally is now an array of statements (as they inherit from AST_Block). Avoiding calling superclass's _walk function in walkers (turns out we walked a node multiple times). Mihai Bazon
2012-09-03jumps, try and definitions are statements tooMihai Bazon
2012-09-03an AST_If is too a StatementWithBodyMihai Bazon
2012-09-03a LabeledStatement should be in fact a StatementWithBody...This fixes output for: if (foo) { moo: if (bar) { break moo; } } else { baz(); } (the labeled statement must be outputted inside brackets) Mihai Bazon
2012-09-03switch branches must be declared `required` so that the compressor doesn't...replace nodes with a single statement. looks stable for now, though mess begins to sink in. need to review the AST hierarchy. Mihai Bazon
2012-08-28docstring for AST_StatementWithBodyMihai Bazon
2012-08-28fix code generator for this case:...if (foo) { with (bar) if (baz) x(); } else y(); (the compressor removes the brackets since the consequent consists of a single statement, but the codegen must include the brackets because otherwise the `else` would refer to the inner `if`) Mihai Bazon
2012-08-27update (c) yearsMihai Bazon
2012-08-22added licenseMihai Bazon
2012-08-22wrote more of the compressor and added some testsMihai Bazon
2012-08-22declare some properties in the node constructor so that they're copied in cloneMihai Bazon
2012-08-21hint that brackets may be required in AST_BlockStatementMihai Bazon
2012-08-21cleaned up some mess and started the actual compressorMihai Bazon
2012-08-21some reorganization...(moved pretty much everything that relates to scope in scope.js, added a module for NodeJS that can be used with require() and exports everything.) Mihai Bazon
2012-08-21handle labels properly...(they can't be handled the same way as variables in a scope) Mihai Bazon
2012-08-21more fixes:...- added walker for AST_ObjectProperty - handle redefinitions properly (only mangle one symbol, make them all point to a single definition) DynarchLIB seems to run fine after mangling + compressed output. Mihai Bazon
2012-08-20added mangler and other stuffMihai Bazon
2012-08-20doc (WIP)Mihai Bazon
