  • lib/rgl/dot.rb, lib/rgl/rdot.rb, tests/TestRdot.rb: Move the DOT module into the RGL module

  • Rakefile, lib/rgl/transitiv_closure.rb, lib/rgl/transitivity.rb, tests/TestTransitiveClosure.rb, tests/TestTransitivity.rb: Feature 21641: Added transitive reduction functionality

    • Updated the gem description to announce this functionality * Moved the transitive closure functionality into the transitivity.rb file along with the transitive reduction funtionality * Modifed the transitiv_closure.rb file to simply load the transitivity.rb file for backward compatibility * Moved all transitivity tests into TestTransitivity.rb

2008-08-23 15:45 javanthropus

  • lib/rgl/condensation.rb, lib/rgl/transitiv_closure.rb, tests/TestTransitiveClosure.rb: Defect 21630: Fixed transitive closure

    • The fix is based on the algorithm described in the documentation for the implementation of transitive closure in Boost * Along with the fix, performance is improved to O(|V||E|)
    • This implementation needs graph condensation, so that function was added as well * More tests were added to cover more corner cases

2008-08-23 05:40 javanthropus

  • lib/rgl/dot.rb, lib/rgl/rdot.rb, tests/TestDot.rb, tests/TestRdot.rb: All IDs for DOT objects, including names, options, and values, are now automatically quoted as necessary according to the rules documented at https://www.graphviz.org/doc/info/lang.html and https://www.graphviz.org/Documentation/dotguide.pdf.

    Labels are handled specially in order to account for \l, \r, and \n sequences but are otherwise treated the same as other options.

    New tests were added to confirm proper function.

    Some changes were made in order to remove explicit quotes from labels which are no longer necessary.
