Scala 2.13 and Doobie 0.8.4

v0.5.0

Scala 2.13, Doobie 0.8.4

Count and Exists methods

• count filtered rows
• check if filtered rows are non-empty
• more build-in filters (IN, BETWEEN, LIKE)
• various fixes to issues detected during testing

Filtering redesigned

Filtering was redesigned to use power of higer-kinded data more efficiently - instead of a select object that checks if particular field is equal to some value, now we have the option to extend filtering.

Repositories joining functionality

• repositories can be joined to filter and return tuples of entities
• fixed bug with limit SQL generation in pagination
• DefaultColumnNames utility for providing a sane defaults for column names settings
• repository.emptySelect utility as for creating filters/updates from an empty value and providing only changes

Reworked initial design

• instead of "obligatory" and "selectable" fields, for simpler cases all fields can be wrapped in the same F[_] - where and set part will be done using different objects in update query instead of one with different roles of particular fields,
• this way for simple vases you need only one F[_] - another one is needed only when you your create object differs from fetched entity because some fields are generated by database,
• fetching supports now pagination,
• queries in Repo are now generated by utilities that can be used by API user as well.

Initial release

• proof of concept
• basic CRUD operations
