2009-06-17Change Guile license to LGPLv3+Neil Jerram1-14/+13
(Not quite finished, the following will be done tomorrow. module/srfi/*.scm module/rnrs/*.scm module/scripts/*.scm testsuite/*.scm guile-readline/* )
2009-02-22compile for-inAndy Wingo1-24/+27
* module/language/ecmascript/base.scm (prop-keys): New method, returns the list of keys of props of this instance. * module/language/ecmascript/impl.scm: Refactor the global object into a special kind of module object. Provide a prop-keys implementation for module objects. * module/language/ecmascript/compile-ghil.scm (comp): Compile for-in. * module/language/ecmascript/impl.scm: Reshuffly things, and implement make-enumerator, a helper for use in for-in statements. * module/language/ecmascript/parse.scm (parse-ecmascript): Fix parsing of for (var foo in bar) {}...
2009-02-22add scheme integration to js via `require'Andy Wingo1-0/+26
* module/language/ecmascript/impl.scm: Add <js-module-object>, that wraps a module. Add js-require, a javascript-happy function that returns an object that wraps a Guile module. Bind it to `require' in the default environment.
2009-02-22more arithmetic on non-numbersAndy Wingo1-1/+30
* module/language/ecmascript/compile-ghil.scm (comp): Convert to number on unary +. * module/language/ecmascript/impl.scm: Define -, *, /, <, <=, >=, > operations on non-numbers.
2009-02-22+ for strings, global js object, new Foo() worksAndy Wingo1-1/+51
* module/language/ecmascript/array.scm (*array-prototype*): Declare the constructor. * module/language/ecmascript/base.scm (pput, pdel): Remove some needless checks. (new): Move definition of new here, and use the constructor. * module/language/ecmascript/compile-ghil.scm (compile-ghil): Add a stub so that when we load a compiled JS program, we make sure the runtime has been booted. * module/language/ecmascript/function.scm (js-constructor): Export a js-constructor method instead of a new method. * module/language/ecmascript/impl.scm (<js-global-object>): Define a new class for the global "this" object, wrapping bindings from the current module. (init-js-bindings!): Define the dozen or so global properties, in the current module. (+): Define addition operations for non-numbers. This is efficient because the generics are only dispatched if the fast-path fails.
2009-02-21implement do, while, forAndy Wingo1-3/+2
* module/language/ecmascript/compile-ghil.scm (comp): Use ghil-bind when making temp vars, so that disassembly understands things. Implement do, while, and for. * module/language/ecmascript/parse.scm (parse-ecmascript): Some tweaks. * module/language/ecmascript/impl.scm (language): Export ->boolean.
2009-02-21implement more operationsAndy Wingo1-3/+21
* module/language/ecmascript/base.scm: Implement some more robust property getters that convert strings to symbols. Implement has-property?. * module/language/ecmascript/compile-ghil.scm (comp): Implement lots more mathematical operators. We now do all expressions; on to statements. * module/language/ecmascript/impl.scm: Define some math helpers. They probably need to call ->number on some things. * module/language/ecmascript/parse.scm (parse-ecmascript): Fix a typo.
2009-02-21implement ++, --, new, delete, void, typeofAndy Wingo1-1/+11
* module/language/ecmascript/compile-ghil.scm (@impl): Implement with @implv. (comp): Implement ++ and -- (pre- and post-). Quite a pain. I'll be looking for ways to simplify this notation. Also implement new, delete, and void. * module/language/ecmascript/impl.scm: Implement typeof.
2009-02-21handle "this" in ecmascriptAndy Wingo1-1/+4
* module/language/ecmascript/base.scm: * module/language/ecmascript/compile-ghil.scm: * module/language/ecmascript/impl.scm: * module/language/ecmascript/parse.scm: Compile "method calls" in such a way that "this" gets propagated correctly.
2009-02-21implement more of the standard runtimeAndy Wingo1-212/+8
* module/language/Makefile.am: * module/language/ecmascript/impl.scm: * module/language/ecmascript/array.scm: * module/language/ecmascript/base.scm: * module/language/ecmascript/function.scm: Split out the runtime into different files. Implement more of the spec's runtime.
2009-02-19support foo["bar"] in addition to foo.barAndy Wingo1-23/+22
* module/language/ecmascript/parse.scm (parse-ecmascript): And update the function declaration forms for the new var syntax. * module/language/ecmascript/compile-ghil.scm (comp): Support foo["bar"] in addition to foo.bar. * module/language/ecmascript/impl.scm (pget, pput): Some fixes for when we get non-symbols -- it can happen, yo. I suppose we should allow for non-string keys too..
2009-02-19implement object literalsAndy Wingo1-1/+9
* module/language/ecmascript/impl.scm: * module/language/ecmascript/compile-ghil.scm (comp): Object literals. * module/language/ecmascript/parse.scm (parse-ecmascript): Fix some object literal parsing.
2009-02-19property gets and puts implemented, yaysAndy Wingo1-1/+2
* module/language/ecmascript/compile-ghil.scm (@impl): Ok, don't recurse on args here. (comp): Implement property gets and puts and lexical assignment. (comp-body): Fix scanning of var forms. * module/language/ecmascript/impl.scm (prop-attrs): Allow for the prop attr array to be #f. * module/language/ecmascript/parse.scm (parse-ecmascript): Fix assignment parsing.
2009-02-19add array supportAndy Wingo1-2/+46
* module/language/ecmascript/compile-ghil.scm (@impl): Whoops, fix this macro. (comp): Handle array literals. * module/language/ecmascript/impl.scm: Add support for arrays.
2009-02-19further ecmascript workAndy Wingo1-0/+184
* libguile/vm-i-system.c (drop, return): Declare drop and return as popping one arg from the stack. * module/language/ghil/compile-glil.scm: * module/language/glil/compile-assembly.scm (make-meta): Adjust so that we declare 'drop and 'return calls as popping one arg from the stack. * module/language/ecmascript/compile-ghil.scm (comp, comp-body): Flesh out a bit more. Most significantly, scoping within functions obeys javascript semantics better, modulo bits about with() forms. * module/language/ecmascript/impl.scm: Define some runtime helper routines. * module/language/Makefile.am (SOURCES): Add impl.scm. * module/language/ecmascript/parse.scm (parse-ecmascript): Minor tweaks. * module/language/ecmascript/tokenize.scm (read-identifier): Identifiers now read as symbols, not strings.
