Find Functions by Signature

Search for functions using input/output examples. Perfect for discovering the right function when you know what you want to achieve but not which function to use.

To search for a function enter arguments separated by commas and result after another comma. For example to search for function that concatenates two arrays enter "[:first, :list], [:plus, :second], [:first, :list, :plus, :second]".

Search Results

Enum.concat([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

Kernel.++([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

List.flatten([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

:erlang.++([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

:erlang.append([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

:lists.append([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

:lists.flatten([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

:lists.merge([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

:lists.umerge([:a, :b], [:c, :d]) → [:a, :b, :c, :d]

:string.concat([:a, :b], [:c, :d]) → [:a, :b, :c, :d]
