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.

2013-12-05AST_Catch shouldn't really inherit from AST_Scope. Fix #363Mihai Bazon
I hereby acknowledge that figure_out_scope has become a mess.

Fix #344
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

2013-09-02Fix names.Mihai Bazon
2013-09-02Disallow `continue` referring to a non-IterationStatement. Fix #287Mihai Bazon
Simplifies handling of labels (their definition/references can be easily figured out at parse time, no need to do it in `figure_out_scope`).

2013-01-17Fix output for arrays containing undefined values.David Glasser
1b6bcca7 was a first attempt at this. That commit made Uglify stop replacing holes with undefined, but instead it started replacing undefined with holes. This is slightly problematic, because there is a difference between a hole and an undefined value. More problematically, it changed [1,undefined] to [1,] which generally doesn't even parse as a hole (just as a trailing comma), so it didn't even preserve the length of the array! Instead, parse holes as their own special AST node which prints invisibly.
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 typesMihai Bazon
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
2012-10-22more sequence optimizations (lift some sequences above binary/unary ↵Mihai Bazon
expressions so that we can avoid parens)
2012-10-18more optimizations for some break/continue casesMihai Bazon
2012-10-12remove the $self hackMihai Bazon
operations are destructive anyway, so there's no point to clone the nodes in the transformer. speed++
2012-10-12fix in_boolean_context() (two tests were broken)Mihai Bazon
2012-10-11cleanupMihai Bazon
- use prototype-less objects where feasible (minor speed improvement) - get rid of HOP
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

2012-09-23properly 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.
