Evaluate code in a resource function definition notebook

Contributed by: Richard Hennigan and Bob Sandheinrich

ResourceFunction["EvaluateDefinitionNotebookSection"][]

evaluates the definition section in the current InputNotebook[].

ResourceFunction["EvaluateDefinitionNotebookSection"]["section"]

evaluates the named section in the current InputNotebook[].

ResourceFunction["EvaluateDefinitionNotebookSection"][nb]

evaluates the definition section in the given notebook.

ResourceFunction["EvaluateDefinitionNotebookSection"][nb,"section"]

evaluates the named section in the given notebook.

Details and Options

The notebook nb should be a NotebookObject expression, typically given by functions like EvaluationNotebook, InputNotebook, Notebooks or ResourceFunction["ClickedNotebook"].

Some typical sections include "Definition", "Examples" and "Tests".

Definitions are defined as standard symbols in the current $Context, not as ResourceFunction objects.

Re-evaluating definitions from a definition notebook is not guaranteed to give the same definitions as the resource function itself.

Using ResourceFunction["EvaluateDefinitionNotebookSection"] to evaluate a section is equivalent to selecting that section's cell group and pressing

.

Examples

Basic Examples (2)

Evaluate the definition section of a function resource notebook:

In[1]:=

Out[1]=

In[2]:=

Out[2]=

View the evaluated cells:

In[3]:=

Out[3]=

Verify that the function is defined:

In[4]:=

Out[4]=

In[5]:=

Retrieve a resource function definition notebook and evaluate the definitions:

In[6]:=

Out[6]=

The function is now defined:

In[7]:=

Out[7]=

Scope (4)

Get a definition notebook:

In[8]:=

Out[8]=

Define the function by evaluating the "Definition" section:

In[9]:=

Out[9]=

Run the tests:

In[10]:=

Out[10]=

Run the examples:

In[11]:=

Out[11]=

In[12]:=

Properties and Relations (2)

Evaluate the "Data Definitions" section of a data resource notebook:

In[13]:=

Out[13]=

In[14]:=

Out[14]=

View the evaluated section:

In[15]:=

Out[15]=

In[16]:=

EvaluateDefinitionNotebookSection can work on any notebook that has cell groups with CellTags set for the first cell in the group:

In[17]:=

nb = CreateDocument[{
Cell["First Section", "Section", CellTags -> "ThisOne"],
ExpressionCell[Defer[1 + 1], "Input"],
Cell["Second Section", "Section", CellTags -> "ThatOne"],
ExpressionCell[Defer[2 + 2], "Input"],
ExpressionCell[Defer[3 + 3], "Input"]
}]

Out[17]=

Evaluate the first section:

In[18]:=

Out[18]=

Evaluate the second section:

In[19]:=

Out[19]=

In[20]:=

Possible Issues (1)

If the section does not exist in the notebook, an error message will be printed:

In[21]:=

Out[21]=

In[22]:=

Out[22]=
