Function Repository Resource:

LocalResourceObjects

Source Notebook

Get a list of locally stored resource objects

Contributed by: Bob Sandheinrich

ResourceFunction["LocalResourceObjects"][]

returns a list of all resource objects stored on the computer.

ResourceFunction["LocalResourceObjects"][types]

only returns resources of the specified types.

ResourceFunction["LocalResourceObjects"][types,prop]

gives the property prop for each resource.

Details and Options

Locally stored resources include both cached resources from the public repositories and custom resources created on the computer.
Published resources are considered locally cached if the resource object information has been retrieved, even if the contents or data of the resource have not been downloaded from the repository.
Typically, resource types correspond to a published repository:
The types can be either a single resource type or a list.
The property prop supports any property supported by ResourceObject[][prop], including "Name", "Description" and "ResourceType".
LocalResourceObject supports the option MaxItems with default value Infinity.

Examples

Basic Examples (2) 

List all locally stored resource objects:

In[1]:=
ResourceFunction["LocalResourceObjects"][] // Short
Out[1]=

Find a few locally stored neural net resource objects:

In[2]:=
ResourceFunction["LocalResourceObjects"]["NeuralNet", MaxItems -> 3]
Out[2]=

Scope (6) 

Find resources of multiple types:

In[3]:=
ResourceFunction["LocalResourceObjects"][{"Data", "Function"}, MaxItems -> 10]
Out[3]=

Display names for all local data resources:

In[4]:=
ResourceFunction["LocalResourceObjects"]["Data", "Name"] // Short
Out[4]=

Retrieve a NetModel for each "NeuralNet" resource using the name for a label:

In[5]:=
Labeled[NetModel[#], #] & /@ ResourceFunction["LocalResourceObjects"]["NeuralNet", "Name", MaxItems -> 3]
Out[5]=

Retrieve a ResourceFunction for each "Function" resource:

In[6]:=
ResourceFunction /@ ResourceFunction["LocalResourceObjects"]["Function", MaxItems -> 10]
Out[6]=

Find a few locally cached resources from the public resource system:

In[7]:=
RandomChoice[
 Select[ResourceFunction[
   "LocalResourceObjects"][], #["RepositoryLocation"] === URL[$ResourceSystemBase] &], 7]
Out[7]=

Find a random ResourceObject created on this computer:

In[8]:=
RandomChoice[
 Select[ResourceFunction[
   "LocalResourceObjects"][], ! MatchQ[#["RepositoryLocation"], _URL] &]]
Out[8]=

Neat Examples (1) 

Create a dynamic tool for browsing locally cached resource functions:

In[9]:=
ResourceFunction["DynamicListView"][
 With[{n = #}, Button[n, CopyToClipboard[ResourceFunction[n]]]] & /@ Sort[ResourceFunction["LocalResourceObjects"]["Function", "Name"]], 10]
Out[9]=
