Ian Piumarta	1acd725af0	Default grammar is part of PEG VM frame. RULE2 and CALL2 change the default grammar for the duration of the rule being called.	пре 10 месеци
Ian Piumarta	1bf9944ff1	String literals make fresh copies of themselves every time they are evaluated.	пре 10 месеци
Ian Piumarta	4065107170	String_append(), _appendAll(), and _format() allocate new memory to allow raw pointers to old content to persist. Add PEG operations TEST (fail if function returns false) and RULE2 (call rule in other grammar). PEG instruction's second operand is object not integer. Initialise top level state.variables with empty object in vmRun(). PEG instruction FAIL removes all actions added by its rule.	пре 10 месеци
Ian Piumarta	7e46198826	Fix double-eval bug in apply(). Grow buffers by more than 1 wherever performance matters.	пре 11 месеци
Ian Piumarta	ea38861c4d	vmCompile() checks that all PC destinations are in range. STRING and CLASS opcodes read the argument length from their string, ignoring the explicit length given in the program.	пре 11 месеци
Ian Piumarta	1ea2557f7e	Fix digitValue() and reading of numerical escaped characters in strings. Indexing a string always returns an unsigned char value. Add PEG VM and corresponding primitive __match__().	пре 11 месеци
Ian Piumarta	c10c320d4e	Add profiling support when compiled with PROFILE=1 and command-line option -p to enable profiling. Add [from:to] syntax for array and string slices. Fix passing of environment between primitive and user-defined __eval__ methods.	пре 11 месеци
Ian Piumarta	4b75732a7e	Support super.id() to call method id in the delegate of the object in which the currently running method was found. Add __extern__ to support foreign function calls.	пре 11 месеци
Ian Piumarta	f2e790cb26	Add String.bitSet, .bitClear, .bitInvert, bitTest, .charClass, .compareFrom.	пре 11 месеци
Ian Piumarta	e57242eb5d	Prefix 'local' constrins variables to be in current scope. Variable references, inrement operator l-values, and function definitions can all be qualified 'local' or 'global'.	пре 11 месеци
Ian Piumarta	4622db9d34	Simplify variable lookup and implicit variable declarations.	пре 11 месеци
Ian Piumarta	2983237af0	Object.push(x) returns self, not x.	пре 11 месеци
Ian Piumarta	2171f47dce	Fold constants during parsing if FOLDCONST=1.	пре 11 месеци
Ian Piumarta	4d396d6170	Fix floating point comparison and assignment operators.	пре 11 месеци
Ian Piumarta	883a9cf7c2	Remove let and ::. Add global keyword. Add Ref/Get/SetSym. Cast the 0 terminator in genericError to oop to ensure va_arg picks it up. Better error messages for broken statements in blocks and broken expressions in argument lists.	пре 11 месеци
Ian Piumarta	dcbef49750	Exceptions are supported with syntax "try {} catch (e) {}", "try {} ensure {}", and "raise e". Add catch to the list of words that can end an expression statement. Most runtime errors are reported using exceptions when EXCEPTIONS=1. Add String_repeat() supporting multiplying a string and an integer. Illegal escape sequence in a string is a warning not an error. Break and continue work properly in while(). ForFromTo evaluates its start and end arguments. Rename primitive fatal() to error().	пре 11 месеци
Ian Piumarta	46c7ef6f32	Run the first non-option command line argument as the program. Set _argv__ to program name plus any following command-line arguments.	пре 11 месеци
Ian Piumarta	2fcfaa962b	Primitives have a unique integer index to identify them. Add String_appendString(base, ext) with the obvious behaviour. Rename newStringEscaped -> newStringUnescaped to describe its operation not its input. Add String_escaped() to replace non-graphic characters. Add String_push() to append characters or strings. Add __primitives__ containing an array of all primitives. Add reverseString() that reverse a string in-place. Add reverseObject() that reverses an object in-place. Add reversed() that returns a reversed copy of an object or string. Fix Let_codeOn() to avoid the # in front of the variable name. Add /* ... */ syntax for multi-line, nesting comments. Add method String.new() to make a new, empty string. Add methods String.escaped(), String.unescaped(). Add method String.push() to append a character or another string. Add method String.pop() to remove and return the last character. Add methods String.asInteger(), String.asFloat(), String.asSymbol(). Provide an implementation of strnstr() for C libraries that lack it. Add method Object.includes() that searches indexable part of an object. Add method String.includes() that searches for characters or strings. Add String.sliced(start, stop) that returns a sub-string. Add method Symbol.asString(). Add method Object.findKey(). Add primitive reversed(). Add methods Symbol.getopt() and Symbol.setopt(). Add method Symbol.defined() that checks the global value, whereas the defined() primitive checks all visible bindings. Add method Symbol.define() to set the global value. Add method Symbol.value() to retrieve the global value. Add method Symbol.allInstances().	пре 1 година
Ian Piumarta	09c41142f3	<type>.eval methods are installed in all built-in object types when TYPECODES=1. println() prints object properties in alphabetical order.	пре 1 година
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.	пре 1 година
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().	пре 1 година
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.	пре 1 година
Ian Piumarta	057733b85f	Binary operators store pointer to implementation to avoid operator selection during eval.	пре 1 година

Ian Piumarta	5ca296eb47	Add return, break, and continue.	пре 1 година
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.	пре 1 година
