[imp-dev] dates and times for pdb
|
Dear imps,
My colleague at CWI, Mark Hills, has constructed an extension to PDB
to be able represent dates and time. He's added the DateTime type and
value representations, parallel to the other types (location, integer,
relation).
This feature is very much wanted by the Rascal team for representing
source code facts that are tied to version repositories. By having
this information first class, instead of encoded in integers or
something, we can provide standard
API and standard visualizations that can interpret dates and times in
a meaningful manner. For example, charts that have dates on the X axis
and code churn on the Y axis can now be fed by a relation with such a
type: rel[datetime, int],
and so on.
I plan to apply the patches soon (i.e. in the next two weeks).
Cheers,
Jurgen
