DATR 2.11.0 is mainly a consolidation release of all the recent changes in the DATR 2.10 series. DATR 2.11 is intended as the final release of DATR 2, with a new DATR 3 currently under development. There may be one or two more bug-fix releases, but no major developments.

winDATR 2.11.0 (the freestanding Windows version) is unchanged apart from its use of DATR 2.11.0.

Examples 2.11.0 is an archive of DATR examples. Note that not all of these work with DATR 2.11.0, due to version differences and a few typos etc..

Features

A few key features of DATR 2.11.0 include:
  • Support for SWI prolog added.
  • Extension to node identifier syntax. Nodes can now be preceded with (Java-style) package identifiers, for example: 
    

    mylex.nouns.House: 


        <> == mylex.core.Noun


	    <root> == house


    .
    Package identifiers are parsed as attributes (lower case first letter) - the capitalisation convention applies to the final node name component.
  • Extension to the variable declaration syntax. Previously, because '-' was a separator between positive and negative ranges, it was not possible to specify '-' as a value in a range. Now you can do this by specifying '-' twice consecutively in a range (positive or negative), for example: 
    

    # vars $x: a - - b.      % range is a, -, b


    # vars $x: a - - - b.    % range is a, - minus b


    # vars $x: a - b - -.    % range is a minus b, -
    The only case not covered is a negative range consisting of just '-', because in three '-' signs, it is always the last one that is interpreted as the separator.
  • #show now supports (restricted) variables and iterates through all specified values.
