  • 1acd725 (HEAD -> master) Default grammar is part of PEG VM frame. RULE2 and CALL2 change the default grammar for the duration of the rule being called. by Ian Piumarta 2024-07-10 11:32:25 +0900

  • 4065107 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 Ian Piumarta 2024-07-04 10:11:13 +0900

  • ea38861 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. by Ian Piumarta 2024-06-20 03:24:32 +0900
  • 1ea2557 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__(). by Ian Piumarta 2024-06-20 02:34:32 +0900
  • c10c320 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. by Ian Piumarta 2024-06-18 15:58:54 +0900

  • 1fd5a0b New reference output. by Ian Piumarta 2024-05-30 18:06:08 +0900
  • e57242e 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'. by Ian Piumarta 2024-05-30 14:49:20 +0900
  • 4622db9 Simplify variable lookup and implicit variable declarations. by Ian Piumarta 2024-05-29 14:22:07 +0900
  • 2983237 Object.push(x) returns self, not x. by Ian Piumarta 2024-05-29 11:05:38 +0900

  • ea60878 Add exception tests. New test.txt reference output. by Ian Piumarta 2024-05-26 17:59:13 +0900
  • 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 Ian Piumarta 2024-05-26 17:58:27 +0900
  • 207ef22 Upate test reference output. by Ian Piumarta 2024-05-26 11:00:04 +0900

  • 2fcfaa9 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 Ian Piumarta 2024-05-23 16:43:43 +0900

  • f75c06c Target minproto-opt built with TYPECODES and DELOPT enabled. Target release profiles with -O to disable backtrace. by Ian Piumarta 2024-05-21 09:12:30 +0900
  • 09c4114 <type>.eval methods are installed in all built-in object types when TYPECODES=1. println() prints object properties in alphabetical order. by Ian Piumarta 2024-05-21 09:10:34 +0900
  • c5c29bd Add release target that uses profile guided optimisation. by Ian Piumarta 2024-05-20 08:49:14 +0900
  • 5e59fa5 Restore original benchmark size and number of repeats. by Ian Piumarta 2024-05-20 08:48:18 +0900
  • 4ac12f9 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 Ian Piumarta 2024-05-18 08:50:43 +0900
  • 2761c99 Object.dump() uses Object.allKeys() instead of Object.keys(). by Ian Piumarta 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 Ian Piumarta 2024-05-15 19:20:04 -0700
  • ff3dda9 Include recent results as comments. by Ian Piumarta 2024-05-15 18:38:14 -0700

  • 057733b Binary operators store pointer to implementation to avoid operator selection during eval. by Ian Piumarta 2024-05-14 06:34:30 +0900

  • 57fe021 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 Ian Piumarta 2024-05-10 03:20:02 +0900
