Generate a pattern that matches a resource function

Contributed by: Bob Sandheinrich

ResourceFunction["ResourceFunctionPattern"][rf]

creates a pattern that will match instances of the ResourceFunction rf.

ResourceFunction["ResourceFunctionPattern"]["name"]

creates a pattern that will match ResourceFunction objects with the named "name".

Details

ResourceFunction["ResourceFunctionPattern"]["name"] creates a pattern will match any resource function with the same name.

ResourceFunction["ResourceFunctionPattern"][rf] matches based on the unique ID inside rf and will not match other resource functions.

Attempting to match objects with a ResourceFunction head is more likely to success using ResourceFunction["ResourceFunctionPattern"][rf].

ResourceFunction["ResourceFunctionPattern"][ResourceFunction["name"]] is a convenient way to ensure the more powerful matching.

Examples

Basic Examples (3)

Test if a ResourceFunction matches a pattern based on the name:

In[1]:=

Out[1]=

See the pattern for a name:

In[2]:=

Out[2]=

Test against a pattern created from the ResourceFunction:

In[3]:=

Out[3]=

Other functions do not match:

In[4]:=

Out[4]=

Scope (3)

Filter values using Cases:

In[5]:=

Out[5]=

Filter in values using Select with a MatchQ operator:

In[6]:=

Out[6]=

Create an operator:

In[7]:=

Out[7]=

Match it against a pattern based on the ResourceFunction:

In[8]:=

Out[8]=

Applications (2)

Create a function that takes a specific ResourceFunction as an argument:

In[9]:=

In[10]:=

In[11]:=

Use the function:

In[12]:=

Out[12]=

Create an expression containing resource functions used a objects:

In[13]:=

mathoperations = {
ResourceFunction["FlipFunction"][Divide],
Plus,
ResourceFunction["FlipFunction"][Power],
Times
}

Out[13]=

Replace the objects:

In[14]:=

$mathoperations /. {ResourceFunction["ResourceFunctionPattern"][ ResourceFunction["FlipFunction"]][f_, args___] :> OperatorApplied[f, args]}$

Out[14]=

Properties and Relations (3)

Define two resource functions with the same name:

In[15]:=

Out[15]=

In[16]:=

Out[16]=

They both match a pattern defined with the name:

In[17]:=

Out[17]=

In[18]:=

Out[18]=

They do not match a pattern based on the other ResourceFunction:

In[19]:=

Out[19]=

In[20]:=

Out[20]=

Possible Issues (3)

Create an operator:

In[21]:=

Out[21]=

The match fails based only on a name:

In[22]:=

Out[22]=

Match it against a pattern based on the ResourceFunction:

In[23]:=

Out[23]=
