We are pleased to announce a beta release of an Object-Relational Mapper
(ORM) library for OCaml. It is implemented as a type-conv syntax extension
which auto-generates database save and query functions based on type
declarations.
You can obtain the ORM from Github at http://github.com/mirage/orm , and
GODI packages and MacPorts will be available shortly. Please report issues
to mir...@recoil.org or use the Github issue tracker.
Some example code is:
type t = { foo: string; bar: int } with orm
let db = t_init "my.db" in
t_save { foo="t1"; bar=1 } db;
t_get ~foo:(`Contains "t") db
The only backend supported currently in SQLite, but we are working on some
alternative non-SQL backends (such as Tokyo Cabinet and a git-based version
controlled database). This beta release is a preview to get feedback and
testing from a wider audience.
The Dyntype library provides a convenient way of manipulating types and
values at run-time without having to dive into camlp4. It is described more
fully in a WGT2010 paper at:
