Find what version of the Wolfram Language you need to define a function

Contributed by: Peter Cullen Burbery

ResourceFunction["WLMinVersion"][func]

gives the minimum Wolfram Language version required to evaluate func.

ResourceFunction["WLMinVersion"][ls]

gives the minimum Wolfram Language version required to evaluate functions in the list ls by taking the maximum.

Details

ResourceFunction["WLMinVersion"] uses the resource function SymbolDependencies. This determines the built-in functions used in defining func. Then WolframLanguageData is used to find the most recent version in which one or more of these were introduced.

Examples

Basic Examples (2)

Define a function:

In[1]:=

$OEISLookup[numbers : {__?NumericQ}] := Dataset[MapAt[Map[Association], Key["results"]]@ Association[ URLExecute[ URLBuild[<|"Scheme" -> "https", "User" -> None, "Domain" -> "oeis.org", "Port" -> None, "Path" -> {"", "search"}, "Query" -> {"q" -> StringRiffle[numbers, ","], "fmt" -> "json"}, "Fragment" -> None|>]]]]$

Find what version of the Wolfram Language you need to define this function:

In[2]:=

Out[2]=

Scope (1)

The function works on lists of defined functions by taking the max:

In[3]:=

$randomWordCloud[] := WordCloud[RandomChoice[RandomWord[10], 30]]; randomGraphProduct[{n_, m_}] := GraphProduct[RandomGraph[{n, m}], RandomGraph[{n, m}]];$
