PDT 2.1: Added / improved functionality

Global View

The Context View has been complemented by a “Global View”, which shows the complete call graph of the entire loaded code base. To display it, select “Window → Show View → Other… → Prolog → PDT Global View”. The interaction (double klicking, zoomin, etc.) is the same as in the Context View.

For the time being the call relations shown in the two graphical views are just a subset of those found by the search. This is because they do not use the full search yet (in particular, they completely ignore calls via meta-predicates). We have nevertheless released them looking forward to your feedback and suggestions for improvement. The full search, including a refined version of the meta-predicate analysis, will be integrated in PDT 2.2.
  • Improved search for Primary Definition or Declaration:
    • Show a message if a predicate has no source
    • Show a list of similar predicates if a predicate is undefined – Paul Singleton
    • Show a warning if there are no similar predicates.
  • Improved Reference Search. – Joint work with Jan Wielemaker – By using the SWI-Prolog library predicate prolog_walk_code/1 to find references the PDT now
    • finds only proper calls and metacalls (no more uncalled terms that accidentally unify with the searched term)
    • can determine the exact location of calls in reference search results.
  • Improved presentation of Search results:
    • Definitions show the head of the found clause.
    • References show the call representing the reference.
  • New: Show progress bar while searching so that the initial display of “ 0 matches” does not confuse users. – Paul Singleton
  • Fix: Handle predicates without source in search results.

Editor

  • New: Show a warning before opening large files. What “large” means can be configured in the

PDT Preferences. – Paul Singleton

  • New: Outline: Show the first argument of clauses.

If it is a function term show it as Functor/Arity. – Paul Singleton

  • Fix: If a source file started with a clause head, placing the caret

within the head and triggering a search missed the first character of the head. – Paul Singleton

Prolog Process Configurations

Logtalk support

The following features now work also for Logtalk. – Joint work with Paulo Moura
