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:Mihai Bazon
- 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
2012-10-09add AST_Infinity nodeMihai Bazon
2012-10-09added $propdoc to AST nodes and some cleanupsMihai Bazon
hopefully we can make the AST documentation self-generating
2012-10-09minor AST cleanup (AST_BlockStatement may inherit from AST_Block)Mihai Bazon
2012-10-09add `--ast-help`Mihai Bazon
displays a rather cruel description of the AST classes, derived directly from the node definitions.
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 otherwiseMihai Bazon
referenced and have no side effects
2012-09-21better support for multiple input files:Mihai Bazon
- use a single AST_Toplevel node for all files - keep original source filename in the tokens
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 cleanupsMihai Bazon
- 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
2012-09-11fixed some mess with symbols/scopeMihai Bazon
- 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
2012-09-07checkpointMihai Bazon
2012-09-07fixed tests (need to drop the toplevel block in "expected" if it's a single ↵Mihai Bazon
statement)
2012-09-05cleaned up usage of AST_BlockStatementMihai Bazon
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).
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 StatementWithBodyMihai Bazon
This fixes output for: if (foo) { moo: if (bar) { break moo; } } else { baz(); } (the labeled statement must be outputted inside brackets)
2012-09-03switch branches must be declared `required` so that the compressor doesn'tMihai Bazon
replace nodes with a single statement. looks stable for now, though mess begins to sink in. need to review the AST hierarchy.
2012-08-28docstring for AST_StatementWithBodyMihai Bazon
2012-08-28fix code generator for this case:Mihai Bazon
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`)
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 reorganizationMihai Bazon
(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.)
2012-08-21handle labels properlyMihai Bazon
(they can't be handled the same way as variables in a scope)
2012-08-21more fixes:Mihai Bazon
- 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.
