Ok, maybe I expected a bit too much for the initial version 1.0. But
is it already possible or planned to allow recsel deliver field values
from two tables, joined together with a foreign key or what does the
manual mean with "the ability of records to refer to other records
(sort of foreign keys)"?
Right now the recutils use the information of the "foreign keys"
(compound fields) just to pick the type of the field in the "referenced"
record descriptor.
For the next version it is planned to support joins in recsel. For
example, having a database like:
%rec: Hacker
%key: Name
Name: Mr. foo
%rec: Package
Name: GNU foo
Hacker:Name: Mr. foo
Name: GNU bar
Hacker:Name: Mr. foo
It will be possible to invoke recsel like:
$ recsel -t Hacker -p Name,Package:Name foo.rec
Name: Mr. Foobar
Package:Name: GNU foo
Name: Mr. Foobar
Package:Name: GNU bar
