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. by

dcbef49
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(). by

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(). by

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. by

Object.dump() uses Object.allKeys() instead of Object.keys(). by
2024-05-16 11:40:21 +0900
31e6d2f
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(). by

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. by
