A basic file-based persistency solution for use with frames.
This is an add-on for frames, so you'll need that! See the included settings.lgt for an example of how to include third-party libraries, or even better the settings.lgt included in your installation of Logtalk.
It also depends on a logtalk_library_path(storage, Path) having been defined,
where Path is the directory the files will be persisted too. See the included
settings.lgt for an example of how to do this.
Most of the actual work should just look like magic. Everytime you send a query
to frames::add_frame/4, frames::update_frame/4, or
frames::delete_frame/3-4 the subject of that query will be persisted (or
deleted as appropriate) from the disk. This is done using the daemon mechanism
built into frames.
Additionally two useful predicates are provided:
frames_persistency::persist/1, which will manually persist a collection of frames when that nested dictionary is given as an arguement.frames_persistency::restore/1, which will load a collection of frames from the disk.
