Overture

On the code generator side their is a development version of a C++ code generator back end from another student at Aarhus. KP is working on an Arduino (restricted C++) backend and PJ is helping out with that.

A tool for automatic generation of user interfaces for VDM models has been integrated into Overture. Currently, only VDM++ models are supported. The tool is run as a launch configuration, although breakpoints are not correctly supported yet. For more about the tool, see http://www.thinkmind.org/index.php?view=article&articleid=icsea_2011_17_20_10244

Release Planning

Version 2.1.4 released

Version 2.1.4 was released 20 November, with small bugfixes (grab it at GitHub), with the main legwork done by Luís.

Release Process

From watching Luís go through the release process, Joey has noted some improvements that must be made to the process document, and will deal with them as time permits. Another not-done-by-Joey release is tentatively planned for either 2.1.8 or 2.1.10

Version 2.1.6

Expected in the new year.

Interesting Overture projects:

Separate Git repository for the Overture documents

With the migration of the LRM and Language Board issue tracker to a GitHub repository (https://github.com/overturetool/language), the examples and all of the documents (with a few exceptions, like release notes) were migrated to the new repository. Joey announced to the overture-core list that that should be considered the canonical place for them, and that bug reports pertaining to the examples should be submitted there; this was also noted in Net Meeting 83 minutes with no objection. Marcel has objected, as there is a preference that that issue tracker only be used for LB issues.

During the meeting it was decided to use the LB tracker solely for RMs and not for the LRM. The content of the LB repository moves to a new documentation repository instead. The Overture repository and the associated issues tracker will remain unchanged. An action on Joey has been created - see Net-Meeting 84
