All your favorite functions that act on maps/hashes in clojure, but for ruby like:

• assoc_in
• update_in
• update
• get_in

NOTE:

These functions all return a new hash, they do not modify the original hash

Usage

• assoc_in

RLC.assoc_in({a: 1},[:b],3)# => {a: 1, b: 3}

RLC.assoc_in({a: 1},[:b,:c],3)# => {a: 1, b: {c: 3}}

• update_in

RLC.update_in({},[:a,:b]){ |other| (other || 0) + 2}# => { a: { b: 2 } }

RLC.update_in({a: {b: 1}},[:a,:b]){ |other| (other || 0) + 2}# => { a: { b: 3 } }

• update

RLC.update({},:a){ |other| (other || 0) + 2}# => { a: 2 }

RLC.update({a: 1},:a){ |other| (other || 0) + 2}# => { a: 3 }

• get_in

RLC.get_in({a: 1},[:a])# => 1

RLC.get_in({a: [1,3]},[:a,1])# => 3

RLC.get_in({a: {b: 2}},[:a,:c])# => nil

RLC.get_in({a: {b: 2}},[:a,:c],4)# => 4

my_report_hash.then{RLC.update_in(_1,%w[reportsgroup1], &method(:fill_in_things))}.then{RLC.update_in(_1,%w[reportsgroup2], &method(:add_things))}# => new my_report_hash

Feel free to suggest other functions we can implement in ruby that you miss in clojure
