Telepath

Official documentation: hexdocs.

Installation

Add the following lib to your mix.exs.

defdepsdo[{:telepath,"~> 0.1.0"}]end

Quickstart

Telepath allows you to easily reach data from any elixir struct given a path (like you do in jsonpath or xpath).

Importing Telepath allows you to use the sigil ~t to generate the struct path.

e.g.

~t/hello.world[0]/# ["hello", "world", 0]

With the a modifier, you can exctract atoms instead of strings.

e.g.

~t/hello.world[0]/a# [:hello, :world, 0]

When your struct path is generated, you can use the &Telepath.get/2 function to access the data.

e.g.

importTelepath# for `~t` sigildata=%{node: [%{attr: "value"},%{attr: "value"}]}Telepath.get(data,~t/node/a)# [%{node: "value"}, %{node: "value}]Telepath.get(data,~t/node.attr/a)# ["value", "value"]Telepath.get(data,~t/node[0]/a)# %{node: "value"}Telepath.get(data,~t/node[0].attr/a)# "value"Telepath.get(%{"string_key"=>"value"},~t/string_key/)# "value"
