Lektorlib

A few bits which may possibly be useful to developers of Lektor plugins.

Bits Included

lektorlib.query.PrecomputedQuery

A subclass of lektor.db.Query which yields a pre-computed sequence of children.

This is useful in (at least) two circumstances:

First, when the children to be queried are virtual source objects, the standard lektor.db.Query will not work. This version will.

Second, when we would like to generate a query of a pre-computed subset of a resource's children, this prevents intruducing unnecessary build dependencies. If we used a standard query with a filter applied, it still iterates over all of the parent node’s children, registering dependencies on all of them.

lektorlib.context.disable_dependency_recording

A python context manager which (temporarily) disables lektor’s dependency recording system.

lektorlib.recordcache.get_or_create_virtual

This function is a helper to streamline the caching of virtual source objects in the lektor record cache.

Lektor.db.Pad.get() handles caching for regular records. At present, however, it does not appear that it ever caches virtual source objects, even though its record cache is perfectly capable of doing so.

lektorlib.testing.assert_no_dependencies(match=None)

This context manager is a testing helper which can be used to check that no dependencies are recorded with lektor’s dependency tracking system.
