SET THEORY 0.30.a

Overview
This software project, called set_theory,
aims to provide the Eiffel
(programming language) Community with a rich and expressive
library of classes modeled upon the concepts of set
theory. In order to get details about motivations, design
decisions and a sketch of road-map,
please see https://www.eiffel.org/blog/rosivaldo/2017/09/set-theory.
In the current
state (https://launchpad.net/set-theory/+milestone/0.30.a),
this project deviates
significantly from the one firstly released at
https://launchpad.net/set-theory/trunk.
Instead of rendering here a lengthy justification for the adopted
changes, I prefer to answer any question on that or any other aspect
of the project via e-mail (rosivaldo.fa@gmail.com)
or at https://answers.launchpad.net/set-theory/+addquestion.
Release notes
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”.
