Ian Piumarta	09c41142f3	<type>.eval methods are installed in all built-in object types when TYPECODES=1. println() prints object properties in alphabetical order.	vor 1 Jahr
Ian Piumarta	4ac12f91c5	Add symbols #O, #d, #v and Symbol.setop() primitive. Add primitive method Symbol.setopt(N) to set command-line option at runtime. Add primitive method Symbol.defined() to test if a variable name has been defined. Overload primitive "+" to concatenate strings. Add stack of namespaces, initialised to empty object. refvar() and getvar() search namespaces, from most to least recent, when looking for global variables. setvar() always defines globals in the most recent namespace regardless of any existing shadowed definitions. Make OBJ::NAME a synonym for OBJ.NAME except that OBJ::NAME() applies a function whereas OBJ.NAME() invokes method NAME on OBJ. Add primitive error() to print source location, error message, and backtrace.	vor 1 Jahr
Ian Piumarta	31e6d2ff3d	Primitives have correct names. Primitive Object.keys() returns properties that do not begin with "__". Add method Object.allKeys() that returns properties that do not begin with "__". Add method Object.sorted() to sort indexable elements. Add function sorted() for String and Object. Relations do not consider strings and symbols to be comparable. Printing strings does not include quotation marks at indentation levels 0 and 1. Printing strings escapes control characters at indentation levels other than 0 and 1. Rename SetVar.expr to SetVar.value to be consistent with SetProp and SetArray. Add RefVar, RefProp, RefArray that compute address of assignable value. Add Binops for autoincrement and assignment operators. Any expression can be the subject of increment or assignment operator. Enforce lvalue for increment and assignment operators by semanic check, not in syntax. String literals can contain escaped quotation marks. Keyword:value pairs in parameter lists provide arbitray expressions as default parameter values. Evaluate and assign default parameters values in apply().	vor 1 Jahr
Ian Piumarta	9cc8c3e572	Top-level expressions use the value of symbol __globals__ as the base environment instead of nil. Fix off-by-1 error in nlrPush(). Object.keys() returns keys in alphabetical order.	vor 1 Jahr
Ian Piumarta	057733b85f	Binary operators store pointer to implementation to avoid operator selection during eval.	vor 1 Jahr
Ian Piumarta	2f164a3100	Use spaces instead of tabs to preserve visual alignment in broken tools.	vor 1 Jahr
Ian Piumarta	30facb810c	Add auto increment/decrement and assignment operators.	vor 1 Jahr
Ian Piumarta	4d570df59e	ForToFrom performs update step after continue.	vor 1 Jahr
Ian Piumarta	5ca296eb47	Add return, break, and continue.	vor 1 Jahr
Ian Piumarta	57fe021082	All symbols created with UNDEFINED_TYPECODE by default. AST nodes with undefined typecode are evaluated by invoking the method __eval__ on the node. Typecode is looked up in the immediate delegate of a node only. Object.__eval__() is primitive and returns self.	vor 1 Jahr
Ian Piumarta	4a959a124f	Accessing an undefined variable causes a fatal error.	vor 1 Jahr
Ian Piumarta	ddff3e48e8	Add "let name = value, ... ;" to create local variables.	vor 1 Jahr
Ian Piumarta	3c992f4a13	Remove primitive makeForm (because Closure.fixed is now accessibe from userland).	vor 1 Jahr
Ian Piumarta	72753c6725	All fields of Lambda and Closure are accessible via Object_{get,put}.	vor 1 Jahr
Ian Piumarta	bc3aae1dcb	Block_eval() executes its body in a new environment	vor 1 Jahr
Ian Piumarta	ec29069aa4	import files	vor 1 Jahr
