mdds 0.5.2 released

I’m happy to announce that version 0.5.2 of Multi-Dimensional Data Structure (mdds) is available for download from the link below.

This is a bug fix release. I would like to thank David Tardon for fixing several important bugs as well as implementing some new API’s for flat_segment_tree. In fact, the majority of changes between 0.5.1 and 0.5.2 are from David.

Here is the run-down of the major changes since 0.5.1:

  • flat_segment_tree
    • fixed a crash on assignment by properly implementing assignment
    • fixed several bugs in shift_right():
    • shifting of all existing nodes was not handled properly.
    • leaf nodes were not properly linked under certain conditions.
    • shifting with skip node option was not properly skipping the
      node at insertion position when the insertion position was at
      the leftmost node.
    • implemented min_key(), max_key(), default_value(), clear() and
    • fixed a bug in operator==() where two different containers were
      incorrectly evaluated to be equal.
    • added quickcheck test code.

There is no API-incompatible changes since 0.5.1, so if you are currently using mdds 0.5.1, your code should compile with 0.5.2 without any modifications.

Named range as data source in DataPilot table

I have hinted in my previous post that you can now use a named range as the data source of a DataPilot table, but you couldn’t create a new DataPilot table with a named range as the source.

Well, now you can.

I tried to come up with a clever way to add this functionality, but ended up with just another radio button in the existing source selection dialog (the dialog that pops up when you select Data – DataPilot – Start without an existing DataPilot table).

Here is a screenshot of the new dialog as evidence:

This functionality is currently available on the master branch of LibreOffice. For those of you who can build LibreOffice directly from the repository, go check it out!

For those of you who would rather wait for a released version, this will be available in 3.4 – the next minor release. Refer to this page for more detailed release plan of the upcoming versions of LibreOffice.
