Set Theory 0.30.d "sets (agent specifications)"

0.30.d:
    • Specifications, properties, implementation and tests were rewritten as much as possible to leverage from using agents.
    • Several new features, intended to be used instead of in-line agents, were specified, implemented and tested.
    • Documentation:
        ◦ Still no diagram included (please see the reason in previous release);
        ◦ EiffelStudio still can not render right some samples of code that use class (instance-free) features, causing the classes that have such kind of code be rendered incompletely on automatic documentation (e.g. STI_SET).
0.30.c:
    • Some agent-oriented features were added to classes that model sets and n-tuples; all of such features were specified, implemented and tested.
    • Overall refactoring has heavily reorganized the cluster hierarchy, in order to ease visual (i.e. via diagrams) documenting.
    • Documentation:
        ◦ Though the automatic HTML documentation has been updated (file://$(system_path)/doc/html/index.html), it includes no diagram, which could not be rendered due to the same bug in EiffelStudio already mentioned on release 0.30.a.
0.30.b:
    • Implementation-specific features of sti_sets cluster were put under tests, uncovering several errors unseen when testing only specification features.
0.30.a:
    • General refactoring removed redundant code, saving some 1910 lines of code.
    • Documentation:
        ◦ due too a bug (not yet understood) in EiffelStudio’s documentation generator, the system HTML documentation (file://$(system_path)/doc/html/index.html) was not updated to reflect the current state of the system; inside EiffelStudio, however, clusters’ diagrams were updated properly.
0.30:
    • Implemented features: "sets" clusters, which consist of
        ◦ sts_sets cluster: minimal specification of core concepts in set theory;
        ◦ stp_sets_properties cluster: extended specification of core concepts in set theory;
        ◦ sti_sets cluster: implementation of core concepts in set theory, grounded on previous clusters;
        ◦ stt_sets_tests cluster: test suites for the implementation in sti_sets.
    • Pending features:
        ◦ numbers-related clusters: numeric sets, i.e. N, Z, R and C, specified, implemented and tested according to all previous clusters.
Major releases ahead
Once the current release is consolidated, I will add to the project the clusters “relations”, “functions” and “operations”.
