Visual Prolog 7.3 New Features

Language

• Generic Interfaces and Classes
  • Conversion to generic type
• Monitors with guards
• New operator == (must-unify)
• Universal term type any and the predicate toAny/1->
• The precedence of unary minus is changed (so that power operator has higher precedence)
• New built-in predicate fromEllipsis : (...) -> any* Terms
• Runtime distinction between privately and publicly supported interfaces is removed
• Preparations for supporting 64bit systems: built-in types integerNative and unsignedNative
• Extended versions of built-in predicates toTerm/2-> and tryToTerm/2-> (type as the first parameter).
• Native interfaces support (attributes):
  • inline: Inline structures and strings.
  • union: Functor-less unions.
  • byVal: Passing parameters by value.
• Other new attributes retired, noDefaultConstructorused
• 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

New 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 is redesigned and reimplemented
• IncludedIn and Includes windows is moved to preview pane of project window
• Browse dialog is improved (automatically jump to the 1st occurrence of search entity on locate, save the last dialog position, etc.)
• Find In Files dialog is improved (one result window, F8 for next, mixed case sensitive search mode, state is saved, etc.)
• Namespaces support is improved (it’s possible to put forms, etc. in a namespace)
• IntelliSense feature is strongly improved for typing speed and convenience of work
• Improved tab navigation dialog, use ALT button for filtering [ReadOnly] windows and Del for closing windows
• Simplify project creation: Project Kinds (Console application, GUI application and DLL) instead of UI Strategy and Target Type
• Dump view improvements (Shift+F2)
• Sorting feature in Errors Window, Break points Window, etc
• 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
