Language

Generic Interfaces and Classes

See Generic Interfaces and Classes.

Conversion to Generic Type

Monitors

Monitors with guards

Must Unify Operator

New operator == (must-unify)

Universal term type

any and the predicate toAny/1->

64 bit preparation

Preparations for supporting 64bit systems: built-in types integerNative and unsignedNative

Foreign language interfacing

Native interfaces support (attributes):

  • inline: Inline structures and strings.
  • union: Functor-less unions.
  • byVal: Passing parameters by value.

External resolution is default for predicates declared with apicall calling convention.

  • They cannot have clauses
  • explicit externally resolution is only legal when a DLL is stated

Other language features

  • The precedence of unary minus is changed (so that power operator has higher precedence)
  • Extended versions of built-in predicates toTerm/2-> and tryToTerm/2-> (type as the first parameter).
  • New built-in predicate fromEllipsis : (...) -> any* Terms
  • Runtime distinction between privately and publicly supported interfaces is removed

New attributes

Warnings:

  • Local object predicates which do not use This (and therefore can be declared as class predicates)
  • Unused local constants
  • Condition of foreach statement which has no backtrack point (i.e. mode is not multi or nondeterm)
  • unheckedConversion's that would be illegal on 64 bit platforms (e.g. pointer -> integer)

IDE

Project tree

The project tree is redesigned and reimplemented. The functionality is more or less unchanged, but the performance is improved.

The IncludedIn and Includes windows has been moved to preview pane of project window.

It is now possible to have several packages with same name in a project (which can make much sense when using namespaces).

Browse dialog

The Browse dialog is improved in several smaller respects, including:

  • It automatically jump to the 1st occurrence of search entity on locate
  • The last dialog position is saved for next appearence

Find In Files

The Find In Files dialog is improved in several respects, including:

  • result window is reused for subsequent searches
  • F8 button for next match (Shift+F8 - previous)
  • Prolog case sensitive search mode
  • state is saved for next appearence

Namespace support

The Namespaces support is improved, so that forms, dialogs, etc can be places in namespaces when created.

IntelliSense

The IntelliSense feature is improved for better overview, speed typing and convenience of work.

Tab navigation dialog

The tab navigation dialog functionality has been extended:

  • use ALT button for filtering [ReadOnly] windows
  • use Del for closing windows

Go to Position on Clipboard

The Go to Position on Clipboard (Shift+F2) has been extended to accept a complete exception dump. F8 will go to the next stack entry.

Sorting in various windows

The Errors Window, the Break points Window, etc. has been extended with sorting capabilities (clicking on the top banner).

  • Optimal Set of Includes improved (output, local scopes, etc.)

Debugger

  • Highlighting changed values in variable window
  • View of long lists improvement
  • Speed of restarting is improved
  • Memory break points and fact access (for some types)
  • Multi-threaded application debugging is improved (thread names, break points handling)
  • Multi-line tool tips

PFC

New entities

  • Collection library
    • Algebraic: redBlackSet, leftistPriorityQueue
    • Modifiable: mapM_redBlack, priorityQueueM_leftist, queueM_fact, setM_redBlack
    • Persistent: mapP_redBlack, priorityQueueP_leftist, queueP_fact, setP_redBlack
  • varM modifiable variable
  • linkControl PFC version of the Link common control
  • richEditControl PFC version of the RichEdit common control
  • treeControl PFC model based version of the TreeView common control
  • gdiplus PFC version of GDI+
  • cryptography hash, sha1, md5 & base64
  • eventSource generalization of event notification/listening
  • monitorQueue thread safe queue class based on the monitor facility
  • reflection basic functionalty for code reflection
  • inputStream_null & outputStream_null media-less streams (input is exhausted; outpt throws away)
  • lZ_fileSystem_native Interface to Lempel-Ziv Decompression API functionality
  • shell_api Api level interface to the Windows Shell
  • winsock2_native native bindings to Windows Sockets 2

Extensions and improvements

  • list package:
    • speed: sort, removeDuplicate, drop, min/max, etc.)
    • functionality: isMemberEq (and similar predicates) that uses a determ predicate as test
  • listControl with owner-drawing capabilities
  • uxTheme_native extended with the rest of the functions and the constants from vsStyle.h, etc.
  • Add moving listener/responder to splitTwoControl
  • Add the fraction handling from format to formatTime
  • Speed improvements for:
    • string
    • fileName
    • listViewControl
  • string::rear/2-> returns the rear part of a string
  • Math package: predicates roundToInteger64/1-> and roundToUnsigned64/1->
  • Better handling of default button size
  • msXLM_api update to version 6.0 of various COMponent classes

Others

  • More efficient memory handling; using typed memory allocation for compound terms and internal facts chains
  • Various optimizations for speed and size of generated code
  • New Demo Examples (Commercial Edition only):
    • Parser Generator
    • LZDecompression
    • TreeControlDemo
  • Help on built-in entities
  • VipBuilder: extra option to ignore #requires directives
  • Extend Win32 library (with more names from MS libraries).
  • More context to consult exceptions
  • Linker speed improvement
  • Vault Integration updated to version 5.0.1
