How to get involved

  • participate in discussions on the forums at prolog.logtalk.org
  • contribute to this wiki
  • vote at ICLP 2007 in September.
  • join the ISO committee - see [1]

Motivation

Prolog implementations have progressed substantially since the original ISO standard was written and as a result new predicates are commonly available but may be absent, have different names, or have different semantics. A revision to the standard aims to address these limitations.

Plan

Based on Seattle 2006 meeting minutes (Timeframe: September 30 2006?)

  • A 2: built-in predicates omitted from part 1 of the standard
    • predicate_property/2
    • compare/3
    • callable/1
    • forall/2
    • number_vars/3
    • retractall/1
    • sort/2
    • keysort/2
    • ground/1
    • member/2
    • append/3
    • length/2
    • floating-point arithmetic flags
    • common term testing predicates
    • common meta-predicates
    • common evaluable functors
  • A 3. Mutable objects
  • A 4. DCGs
  • A 7. Multi-threading
  • A 8. Read only flag unification
  • A 9. Unicode
  • Other
