View Source Surface.Catalogue.Data (Surface v0.12.1)
Experimental module that provides conveniences for manipulating data in Examples and Playgrounds.
Provide wrappers around built-in functions like get_in/2 and update_in/3
using a shorter syntax for accessors.
Accessor Mapping
[_]:Access.all/0[fun]:Access.filter(fun)[index]:Access.at(index)(Shorthand for[index: i])[index: i]:Access.at(i)[key: k]:Access.key(k)[first..last]:Surface.Catalogue.Data.slice(first..last)
Example
Data.get(props.lists[_].cards[& &1.id == "Card_1"].tags[-1].name)The code above will be translated to:
get_in(props, [:lists, Access.all, :cards, Access.filter(& &1.id == "Card_1"), :tags, Access.at(-1), :name])Summary
